Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

• Paper: 2-4 weeks
• Orange peel: 6 months
• Milk carton: 5 years
• Plastic bag: 15 years
• Tin can: 100 years
• Plastic bottle: 450 years
• Glass bottle: 500 years
• Styrofoam: Never

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Environmental pollution is the unwarranted discharge of mass or energy into the planet’s natural resource pools, such as land, air, or water, which detriments the environment’s ecological stability and the health of the living things that inhabit it. There is an intensified health risk and pollution in middle and low-income countries due to the increased use of pesticides, industrialization, the introduction of nitrogen-based fertilizers, forest fires, urbanization, and inadequate waste management (Appannagari, 2017). Air pollution, lead and chemicals exposure, hazardous waste exposure, and inappropriate e-waste disposal all result in unfavorable living conditions, fatal illnesses, and ecosystem destruction. The essay will provide an overview of pollution and proffer solutions to combating pollution for a sustainable environment and health.

In addition to hindering economic development and considerably accelerating climate change, pollution exacerbates poverty and inequality in urban and rural areas. The most pain is always experienced by the poor, who cannot afford to protect themselves against pollution’s harmful effects. The main environmental factor contributing to sickness and early mortality is pollution due to premature deaths resulting from pollution (Appannagari, 2017). Due to the unacceptably high cost to human capital and health, as well as the resulting GDP losses, pollution must be addressed. Through initiatives like reducing black carbon and methane emissions, which are responsible for air pollution and climate change, pollution management can also significantly contribute to climate change mitigation (Appannagari, 2017). Additionally, pollution control can promote competitiveness through, for instance, job growth, increased energy efficiency, better transportation, and sustainable urban and rural development. Below are the various approaches for solutions to health and pollution problems.

First, governments should evaluate pollution as a national and international priority and integrate it into the city and country planning process. Pollution affects the health and well-being of societies and, as such, cannot be solely viewed as an environmental issue (The Lancet Commission on Pollution and Health, 2017). All levels of government should give pollution prevention a high priority, incorporate it into development planning, and tie it to commitments regarding climate change, SDGs, and the prevention of non-communicable diseases. Some options are both affordable and offer good returns on investment.

Secondly, governments should increase funding for pollution control and prioritize it by health impacts. There should be a significant increase in the financing for pollution management in low- and middle-income nations, both from national budgets and international development organizations (The Lancet Commission on Pollution and Health, 2017). The most effective international support for pollution reduction is when it mobilizes additional actions and funding from others. Examples include helping towns and nations that are quickly industrializing concerning technical capacity building, regulatory and enforcement support, and support for direct actions to save lives. Monitoring financing initiatives are necessary to determine their cost-effectiveness and to raise accountability.

Thirdly, organizations should work to build multicultural partnerships for pollution control. Public-private partnerships and interagency cooperation can be powerful tools in creating clean technology and energy sources that will ultimately prevent pollution at its source (The Lancet Commission on Pollution and Health, 2017). Collaborations between ministries that include the ministries of finance, energy, development, agriculture, and transport, as well as the ministries of health and the environment, are crucial in pollution control. Governments should promote monitoring systems that could identify and apportion pollution sources, measure pollution levels, guide enforcement, and assess progress toward goals. The use of new technology in pollution monitoring, such as data mining and satellite images, can boost effectiveness, broaden the monitoring area, and cut costs.

One of the main issues facing the world in the current period is pollution. Natural resources are depleting daily due to car emissions, new technologies, factories, and chemicals added to food. All of these factors seriously harm the world. However, the problems caused by pollution can be prevented by building multicultural partnerships, increasing funding for pollution control, integrating it into the country’s planning process, and adopting new technology for monitoring pollution. Preventing pollution lowers the cost to the environment and the economy.

Long Essay On Environmental Pollution

Environmental pollution is one of the biggest threats to our planet today. It affects both the environment and human health, and it’s becoming more and more pervasive in our daily lives. In this essay, we’ll explore what environmental pollution is, how it affects us, and what the most effective solutions are to reduce its impact on people and the planet.

Introduction

There are many different types of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination. Each type of pollution has different causes and effects. Air pollution is typically caused by emissions from factories and automobiles. These emissions can contain harmful chemicals that can cause respiratory problems, heart disease, and cancer. Water pollution is often caused by sewage or agricultural runoff. This pollution can contaminate drinking water supplies and make people sick. Soil contamination can be caused by hazardous waste disposal or mining operations. This contamination can make crops unsafe to eat and cause health problems in people who come into contact with it.

Causes of Environmental Pollution

There are many causes of environmental pollution. The most common cause is the release of harmful chemicals into the environment. These chemicals can come from factories, power plants, cars, and other sources. They can pollute the air, water, and soil. They can also cause health problems for people and animals.

Other causes of environmental pollution include sewage, agricultural runoff, and mining. Sewage can contain harmful bacteria and viruses that can pollute water supplies. Agricultural runoff can contain pesticides and fertilizers that can pollute rivers and lakes. Mining can release harmful metals and minerals into the environment.

Types of Pollutants and Their Impact on the Environment

There are many different types of pollutants that can have an adverse impact on the environment. Some of the most common pollutants include:

• Air pollution – This is one of the most visible forms of pollution and can cause a range of health problems, including respiratory illnesses.

• Water pollution – This can lead to contamination of drinking water supplies and also harm marine life.

• Soil pollution – This can contaminate crops and lead to soil erosion.

• Light pollution – This can disrupt the natural circadian rhythms of animals and cause light-sensitive species to suffer.

All of these pollutants can have a serious impact on the environment, both in terms of the immediate damage they cause and also the long-term effects. It is therefore important to be aware of the different types of pollutants and their potential impacts.

Effects Of Environmental Pollution

There are many effects of environmental pollution. Some of the most common include air pollution, water pollution, and soil contamination.

Air pollution is one of the most harmful forms of environmental pollution. It is a major contributor to respiratory problems, heart disease, and cancer. Air pollution is also a leading cause of climate change.

Water pollution is another major problem caused by environmental pollution. It can contaminate drinking water supplies, damage aquatic ecosystems, and make recreation in waterways unsafe.

Soil contamination can occur when pollutants such as chemicals or oil spills enter the ground. This can make crops difficult to grow and can contaminate food supplies. Soil contamination can also cause health problems if people come into contact with contaminated soil or eat contaminated food.

Prevention and Control Measures

There are a number of things that individuals can do to help prevent and reduce environmental pollution. One of the most important things is to educate yourself and others about the issue and its causes. This can help raise awareness and create a demand for change. Another key prevention measure is to support businesses and industries that are working to reduce their pollution output. This includes voting with your wallet by patronizing companies that have green policies in place, and investing in cleaner energy sources. Finally, you can take action in your own life to reduce your impact on the environment. This includes conserving energy, recycling, driving less, and composting.

In conclusion, environmental pollution has become a major global concern and it is important for us to take proactive steps to reduce the amount of pollutants that are entering our environment. We can start by reducing our consumption of single-use products, switching to renewable energy sources such as solar or wind power, and engaging in conscientious recycling habits. By taking these actions we can help protect our planet from further harm caused by environmental pollution.

What is water pollution?

Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste , petroleum , and disease-causing microorganisms .

What human activities cause water pollution?

Human activities that generate domestic sewage and toxic waste cause water pollution by contaminating water with disease-causing microorganisms and poisonous substances. Oil spills are another source of water pollution that have devastating impacts on surrounding ecosystems.

Sewage can promote algae growth, which can eventually result in eutrophic “dead zones” where aquatic life cannot survive because of a lack of oxygen. Microplastics are often found in marine wildlife and can become concentrated in humans who consume seafood because of biomagnification . Oil spills, such as the Deepwater Horizon oil spill in 2010, strand and kill many different marine species.

While some studies point to human activity as a catalyst for red tide, scientists are unsure about its cause. Red tide is a common term for harmful algal blooms that often poison or kill wildlife and humans who consume contaminated seafood. Red tides can severely impact ecosystems and local economies.

water pollution , the release of substances into subsurface groundwater or into lakes , streams, rivers , estuaries , and oceans to the point that the substances interfere with beneficial use of the water or with the natural functioning of ecosystems . In addition to the release of substances, such as chemicals , trash, or microorganisms, water pollution may include the release of energy , in the form of radioactivity or heat , into bodies of water.

Types and sources of water pollutants

Water bodies can be polluted by a wide variety of substances, including pathogenic microorganisms, putrescible organic waste, fertilizers and plant nutrients , toxic chemicals, sediments, heat , petroleum (oil), and radioactive substances . Several types of water pollutants are considered below. (For a discussion of the handling of sewage and other forms of waste produced by human activities, see waste disposal and solid-waste management .)

Water pollutants come from either point sources or dispersed sources. A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system . A dispersed (or nonpoint) source is a very broad unconfined area from which a variety of pollutants enter the water body, such as the runoff from an agricultural area. Point sources of water pollution are easier to control than dispersed sources, because the contaminated water has been collected and conveyed to one single point where it can be treated. Pollution from dispersed sources is difficult to control, and, despite much progress in the building of modern sewage-treatment plants, dispersed sources continue to cause a large fraction of water pollution problems.

Domestic sewage is the primary source of pathogens ( disease -causing microorganisms) and putrescible organic substances. Because pathogens are excreted in feces , all sewage from cities and towns is likely to contain pathogens of some type, potentially presenting a direct threat to public health . Putrescible organic matter presents a different sort of threat to water quality. As organics are decomposed naturally in the sewage by bacteria and other microorganisms, the dissolved oxygen content of the water is depleted. This endangers the quality of lakes and streams, where high levels of oxygen are required for fish and other aquatic organisms to survive. In addition, domestic sewage commonly contains active pharmaceutical ingredients, which can harm aquatic organisms and may facilitate antibiotic resistance . Sewage-treatment processes reduce the levels of pathogens and organics in wastewater, but they do not eliminate them completely ( see also wastewater treatment ).

Domestic sewage is also a major source of plant nutrients , mainly nitrates and phosphates . Excess nitrates and phosphates in water promote the growth of algae , sometimes causing unusually dense and rapid growths known as algal blooms . When the algae die, oxygen dissolved in the water declines because microorganisms use oxygen to digest algae during the process of decomposition ( see also biochemical oxygen demand ). Anaerobic organisms (organisms that do not require oxygen to live) then metabolize the organic wastes, releasing gases such as methane and hydrogen sulfide , which are harmful to the aerobic (oxygen-requiring) forms of life. The process by which a lake changes from a clean, clear condition—with a relatively low concentration of dissolved nutrients and a balanced aquatic community —to a nutrient-rich, algae-filled state and thence to an oxygen-deficient, waste-filled condition is called eutrophication . Eutrophication is a naturally occurring, slow, and inevitable process. However, when it is accelerated by human activity and water pollution (a phenomenon called cultural eutrophication ), it can lead to the premature aging and death of a body of water.

The improper disposal of solid waste is a major source of water pollution. Solid waste includes garbage, rubbish, electronic waste , trash, and construction and demolition waste, all of which are generated by individual, residential, commercial, institutional, and industrial activities. The problem is especially acute in developing countries that may lack infrastructure to properly dispose of solid waste or that may have inadequate resources or regulation to limit improper disposal. In some places solid waste is intentionally dumped into bodies of water. Land pollution can also become water pollution if the trash or other debris is carried by animals, wind, or rainfall to bodies of water. Significant amounts of solid waste pollution in inland bodies of water can also eventually make their way to the ocean. Solid waste pollution is unsightly and damaging to the health of aquatic ecosystems and can harm wildlife directly. Many solid wastes, such as plastics and electronic waste, break down and leach harmful chemicals into the water, making them a source of toxic or hazardous waste.

Of growing concern for aquatic environments is plastic pollution . Since the ocean is downstream from nearly every terrestrial location, it is the receiving body for much of the plastic waste generated on land. Several million tons of debris end up in the world’s oceans every year, and much of it is improperly discarded plastic litter. Plastic pollution can be broken down by waves and ultraviolet radiation into smaller pieces known as microplastics , which are less than 5 mm (0.2 inch) in length and are not biodegradable. Primary microplastics, such as microbeads in personal care products and plastic fibers in synthetic textiles (e.g., nylon ), also enter the environment directly, through any of various channels—for example, from wastewater treatment systems , from household laundry, or from unintentional spills during manufacturing or transport. Alarmingly, a number of studies of both freshwater and marine locations have found microplastics in every aquatic organism tested. These tiny plastics are suspected of working their way up the marine food chains , from zooplankton and small fish to large marine predators, and have been found in seafood. Microplastics have also been detected in drinking water. Their health effects are unknown.

Waste is considered toxic if it is poisonous , radioactive , explosive , carcinogenic (causing cancer ), mutagenic (causing damage to chromosomes ), teratogenic (causing birth defects), or bioaccumulative (that is, increasing in concentration at the higher ends of food chains). Sources of toxic chemicals include improperly disposed wastewater from industrial plants and chemical process facilities ( lead , mercury , chromium ) as well as surface runoff containing pesticides used on agricultural areas and suburban lawns ( chlordane , dieldrin , heptachlor). (For a more-detailed treatment of toxic chemicals, see poison and toxic waste .)

Sediment (e.g., silt ) resulting from soil erosion or construction activity can be carried into water bodies by surface runoff . Suspended sediment interferes with the penetration of sunlight and upsets the ecological balance of a body of water. Also, it can disrupt the reproductive cycles of fish and other forms of life , and when it settles out of suspension it can smother bottom-dwelling organisms.

Heat is considered to be a water pollutant because it decreases the capacity of water to hold dissolved oxygen in solution, and it increases the rate of metabolism of fish. Valuable species of game fish (e.g., trout ) cannot survive in water with very low levels of dissolved oxygen . A major source of heat is the practice of discharging cooling water from power plants into rivers; the discharged water may be as much as 15 °C (27 °F) warmer than the naturally occurring water. The rise in water temperatures because of global warming can also be considered a form of thermal pollution.

Petroleum ( oil ) pollution occurs when oil from roads and parking lots is carried in surface runoff into water bodies. Accidental oil spills are also a source of oil pollution—as in the devastating spills from the tanker Exxon Valdez (which released more than 260,000 barrels in Alaska’s Prince William Sound in 1989) and from the Deepwater Horizon oil rig (which released more than 4 million barrels of oil into the Gulf of Mexico in 2010). Oil slicks eventually move toward shore, harming aquatic life and damaging recreation areas.

Groundwater —water contained in underground geologic formations called aquifers —is a source of drinking water for many people. For example, about half the people in the United States depend on groundwater for their domestic water supply . Although groundwater may appear crystal clear (due to the natural filtration that occurs as it flows slowly through layers of soil ), it may still be polluted by dissolved chemicals and by bacteria and viruses . Sources of chemical contaminants include poorly designed or poorly maintained subsurface sewage-disposal systems (e.g., septic tanks ), industrial wastes disposed of in improperly lined or unlined landfills or lagoons , leachates from unlined municipal refuse landfills, mining and petroleum production, and leaking underground storage tanks below gasoline service stations. In coastal areas, increasing withdrawal of groundwater (due to urbanization and industrialization) can cause saltwater intrusion: as the water table drops, seawater is drawn into wells.

Although estuaries and oceans contain vast volumes of water, their natural capacity to absorb pollutants is limited. Contamination from sewage outfall pipes, from dumping of sludge or other wastes, and from oil spills can harm marine life, especially microscopic phytoplankton that serve as food for larger aquatic organisms. Sometimes, unsightly and dangerous waste materials can be washed back to shore, littering beaches with hazardous debris. In oceans alone, annual pollution from all types of plastics was estimated to be between 4.8 million and 12.7 million tonnes (between 5.3 million and 14 million tons) in the early 21st century, and floating plastic waste had accumulated in Earth’s five subtropical gyres, which cover 40 percent of the world’s oceans.

Another ocean pollution problem is the seasonal formation of “ dead zones” (i.e., hypoxic areas, where dissolved oxygen levels drop so low that most higher forms of aquatic life vanish) in certain coastal areas. The cause is nutrient enrichment from dispersed agricultural runoff and concomitant algal blooms. Dead zones occur worldwide; one of the largest of these (sometimes as large as 22,730 square km [8,776 square miles]) forms annually in the Gulf of Mexico , beginning at the Mississippi River delta.

Although pure water is rarely found in nature (because of the strong tendency of water to dissolve other substances), the characterization of water quality (i.e., clean or polluted) is a function of the intended use of the water. For example, water that is clean enough for swimming and fishing may not be clean enough for drinking and cooking. Water quality standards (limits on the amount of impurities allowed in water intended for a particular use) provide a legal framework for the prevention of water pollution of all types.

There are several types of water quality standards. Stream standards are those that classify streams, rivers , and lakes on the basis of their maximum beneficial use; they set allowable levels of specific substances or qualities (e.g., dissolved oxygen , turbidity, pH) allowed in those bodies of water, based on their given classification. Effluent (water outflow) standards set specific limits on the levels of contaminants (e.g., biochemical oxygen demand , suspended solids, nitrogen ) allowed in the final discharges from wastewater-treatment plants. Drinking-water standards include limits on the levels of specific contaminants allowed in potable water delivered to homes for domestic use. In the United States , the Clean Water Act and its amendments regulate water quality and set minimum standards for waste discharges for each industry as well as regulations for specific problems such as toxic chemicals and oil spills . In the European Union , water quality is governed by the Water Framework Directive, the Drinking Water Directive, and other laws . ( See also wastewater treatment .)

What is the life-cycle approach and how can it help tackle plastic pollution?

Later this year, negotiators will gather in the Republic of Korea for a fifth round of discussions aimed at developing a legally binding international agreement to end plastic pollution.   

The negotiations are designed to help counter the mounting toll plastic pollution is taking on the planet. Every year, the world produces around 430 million tonnes of plastic, most of which soon becomes waste. This rising tide of plastic debris damages fragile ecosystems, stokes climate change and can result in human exposure to harmful chemicals .  

Central to any solution to plastic pollution is a concept known as the life-cycle approach . It aims to go beyond recycling and reduce the environmental toll that plastic pollution takes at every stage of the life cycle of plastics, from production to its use and disposal. In March 2022, UN Member States agreed to forge an international agreement on plastic pollution embracing the approach .   

“Plastic pollution is a wide-ranging problem and there are many solutions that include shifting away from single-use and short-lived plastic, to ensuring the prolonged use of plastic through reuse systems, to better waste management and recycling,” said Sheila Aggarwal-Khan, the director of the Industry and Economy Division with the United Nations Environment Programme (UNEP). “Recycling alone will not get us out of the plastic pollution crisis. We need a combination of approaches working in tandem across the life cycle of plastic to have a world free of plastic pollution.”  

So, what exactly is the life-cycle approach and how can it help the world deal with plastic pollution in a systemic way? Read on to find out. 

Why is plastic pollution so damaging?  

Plastic products often need to have chemicals added to them to give them their functionality. Some of these are harmful chemicals and may enter the environment or human bodies depending on the production practices, use and disposal. As a result, there is a risk of pollution to the soil, groundwater, the marine environment, or harm to human health. The production of plastic is also responsible for more than 3 per cent of global greenhouse gas emissions, contributing to the climate crisis. This all makes plastic pollution a driver of the triple planetary crisis of climate change , nature and biodiversity loss , and pollution and waste .  

When people talk about the life cycle of plastic, what do they mean?  

Experts refer to the extraction of raw materials, their conversion into products, and use and disposal of a product as its life cycle. In the case of plastic, the story usually begins in the ground . For most of plastic that is fossil fuel based, oil and gas are extracted from the earth and sent to refineries. There, they are transformed into plastic polymers, which are then moulded into products from water bottles and other single-use packaging material—including containers for food and beverage commodities—to fishing gear and products for use in agriculture or in transportation . After they have served their purpose, such products usually find their way to one of four places: a landfill (although often an uncontrolled dumpsite), an incinerator, a recycling or re-use centre and, most damagingly, the environment. 

What is the life-cycle approach to plastic pollution?  

The life-cycle approach looks to limit the potential problems caused by plastic products at every stage of their life, from their production to their disposal. UNEP research has found there are dozens of things that governments and businesses can do to accomplish that goal.  

For example, countries could ban or restrict single-use plastic products or incentivize the development of plastic alternatives. Governments could provide the necessary regulation to send the signal to manufacturers to reduce and eliminate single-use plastic products, and change the product design to ensure plastic products are made of materials that are reusable, prolong their useful life, and that can be recycled at the end of their use. This means having plastic products designed to reduce environmental and human exposure to harmful chemicals across the life cycle of these products.   

Since the plastics sector depends on legions of people around the world, including millions of informal waste pickers , the life-cycle approach also aims to balance socio-economic needs with concerns over plastic pollution.  

Why is the life-cycle approach important?  

Plastic is deeply embedded in our lives and our economies – and plastic pollution continues to mount. Research shows the life-cycle approach could save governments US$70 billion in waste management expenses, and save society US$4.5 trillion in social and environmental costs by 2040. It could also massively reduce the volume of plastics entering the ocean.  

These benefits could be achieved by using the life-cycle approach to inform common design standards, create market incentives and disincentives, and expand reuse schemes, among other things. 

The life-cycle approach is also essential to delivering on key multilateral environmental agreements, such as the Paris Agreement on climate change, and to achieving the United Nations Sustainable Development Goals.  

Why can’t we solve plastic pollution with recycling?  

Recycling is important but it alone isn’t enough to end the plastic pollution crisis. For a start, close to 80 per cent of the plastic in single-use plastic products is not economically viable to recycle . This can be due to design decisions for a plastic product, such as the type of polymer used, and absence of adequate recycling infrastructure, the use of colour additives and combination of materials in a single product, or the use of additives that if harmful, can also pose a health threat to workers in waste management and recycling.  

Additionally, more than 2.7 billion people do not have access to solid waste collection and scaling up recycling infrastructure is challenging.  

“To phase out and ultimately end plastic pollution, there needs to be a combination of solutions across the life cycle of plastics,” said Aggarwal-Khan. “The only way to do that, is with the life-cycle approach.” 

To fight the pervasive impact of pollution on society, UNEP launched #BeatPollution , a strategy for rapid, large-scale and coordinated action against air, land and water pollution. The strategy highlights the impact of pollution on climate change, nature and biodiversity loss, and human health. Through science-based messaging, the campaign showcases how transitioning to a pollution-free planet is vital for future generations.

Essay on Environmental Pollution for Students and Children

500+ words essay on environmental pollution.

Essay on Environmental Pollution – Environment is the surroundings in which we live. But the contamination of our environment by pollutants is environmental pollution. The current stage of the earth that we are seeing is the cause of centuries of exploitation of earth and its resources.

Moreover, the earth cannot restore its balance because of environmental pollution . The human force has created and destroyed life on earth. Human plays a vital role in the degradation of the environment.

Effect of pollution on the health

The environmental pollution, directly and indirectly, affects the lives of humans and other species. These living beings co-existed on the earth with human from centuries.

Effect on Air

Carbon and dust particles string up with the air in the form of smog, damaging respiratory system , haze, and smoke. These are caused by the emission of industrial and manufacturing units by burning of fossil fuels, vehicle combustion of carbon fumes.

Moreover, these factors affect the immune system of birds which become a carrier of viruses and infections.

Besides, it also affects the body system and body organs.

Effects on Land, Soil, and Food

Human’s organic and chemical both waste harm the land and soil with its decomposition. Also, it introduces some chemical in the soil and water. Land and soil pollution mainly caused by the use of pesticides, fertilizers , soil erosion, and crop residues.

Effect on Water

Water gets contaminated easily with any pollutant whether it is human waste or chemical discharge from factories. Also, we use this water for irrigation of crops and drinking. But, because of infection they become contaminated too. Besides, an animal dies because they drink this same contaminated water.

Moreover, around 80% of pollutants of land such as chemical, industrial and agricultural waste end up in the water bodies.

Besides, these water bodies ultimately connect to the sea which means it indirectly pollutes the biodiversity of the sea.

Effect on Food

Because of contaminated soil and water, the crop or agricultural produce also get toxic. Furthermore, this contaminated food effect our health and organs. From the beginning of their life, these crops are laced with chemical components that reach a mass level until the time of harvest.

Effect on Climate

Climate change is also a cause of environmental pollution. Also, it affects the physical and biological components of the ecosystem.

Moreover, ozone depletion, greenhouse gases, global warming all these climate changes are a cause of environmental pollution.

Furthermore, some unstable climate changes are earthquakes, famine, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruption, and avalanches are all because of climate change that happens all because of environmental pollution.

In conclusion, man has exploited the wealth of nature at the cost of his and environments health. Also, the effect that is now emerging rapidly is all because of the activities of humans for hundreds or thousands of years.

Above all, if we wish to survive and continue our life on earth then we have to take measures. These measures will help is securing our as well as our next generation future.

Pollution revealed as the greatest threat to healthy soils

Food security and biodiversity are threatened by the chemicals contaminating our soils.

Earthworms, insects and mites are all at risk from soil pollution, and scientists are worried that we know very little about the damage it’s causing.

Toxic metals and the overuse of pesticides are threatening subterranean life around the world.

New research published in the journal iScience found that soil pollution was the leading cause of declines among organisms living underground. The finding has surprised scientists, who expected farming intensification and climate change to have much greater impacts.

Dr Victoria Burton , a co-author of the new research based at the Natural History Museum, says that the findings are “concerning”.

“Above ground, land use, climate change and invasive species have the greatest impact on biodiversity, so we assumed that this would be similar below ground,” Victoria says. “Our results show, however, that this isn’t the case.”

“Instead, we found that pesticide and heavy metal pollution caused the most damage to soil biodiversity. This is worrying, as there hasn’t been a lot of research into the impacts of soil pollution, so its effects might be more widespread than we know.”

“Amid concern over soil degradation, we need to investigate what impacts other sources of pollution, such as microplastics , hydrocarbons and persistent chemicals, are having on the life beneath our feet.”

The secret life of soils

Compared to life above ground, what’s living in soils is relatively unknown. This is because, in addition to the difficulty in finding the organisms that live down there, soil is actually made up of multiple habitats all sitting on top of each other.

“Soil isn’t just a homogenous lump of dirt,” Victoria says. “It’s a complex environment containing many different structures, nutrients and minerals. While the majority of life is found within 10 centimetres of the surface, some organisms can live much deeper .”

“But with so few specialists who can identify subterranean organisms, we know much less about life below than above ground.”

This means that when it comes to finding out how soil communities are faring, there are a lot of open questions. While it’s known that habitat destruction and persecution are some of the biggest impacts for above ground biodiversity , only a few studies have tried to tackle their subterranean equivalents.

To try and account for this in their new research, the team performed what is known as a meta-analysis. This is where scientists take data from many existing studies and re-analyse them to answer new questions that the original research didn’t focus on.

For this meta-analysis, Victoria and the rest of her team reused the data of more than 600 studies, including thousands of different datapoints, to see what the greatest impacts humans were having on the health of soils globally.

Digging into soil research

Based on their results, wildlife above and below ground generally respond very differently to the same issues.

While the loss of a forest above ground might be devastating to the plants and animals that live there, the researchers’ predictions that subterranean organisms would also be affected weren’t proven. Instead, it seemed that the soil provided a buffer, helping its organisms to be more resilient to certain changes.

“Soils can store moisture and nutrients, which can help life living underground to withstand changes, at least in the short term,” Victoria explains. “For instance, while climate change is affecting more and more species on the surface, its underground impacts appear to be limited for now.”

“However, the effect of these impacts in the long-term is less well-known , meaning this buffering effect may only provide temporary relief for soil communities.”

While the majority of the changes, like rising temperatures or chemical pollution, were negative for soil biodiversity, there were a few positives. The most important was the use of organic fertilisers and mulch, which introduces more carbon into the soil. This is especially beneficial for earthworms, which feed on the nutrients and cycle them in the soil.

Though this study has provided a deeper insight into the changes affecting soils, it’s still barely scratched the surface. The team hope that future research will focus on how the interactions between factors like climate change and pollution, might enhance or limit their joint impacts

They also hope to get more people looking into soils. Victoria is keen to inspire the next generation of researchers while working with students as part of the National Education Nature Park , which is being led by the Natural History Museum.

“I’m excited to include soil biodiversity work within the National Education Nature Park,” Victoria says. “It’s a good opportunity to get young people excited about the life under their feet, and to get them interested in the life cycles of animals like craneflies and beetles which they might not know about.”

“It’s not just an opportunity to inspire them, but to do some important science that is currently being overlooked.”

Essay on Environmental Pollution

The environment is the surrounding of an organism. The environment in which an organism lives is made up of various components like air, water, land, etc. These components are found in fixed proportions to create a harmonious balance in the environment for the organism to live in. Any kind of undesirable and unwanted change in the proportions of these components can be termed as pollution. This issue is increasing with every passing year. It is an issue that creates economic, physical, and social troubles. The environmental problem that is worsening with each day needs to be addressed so that its harmful effects on humans as well as the planet can be discarded.

Causes of Environmental Pollution 

With the rise of the industries and the migration of people from villages to cities in search of employment, there has been a regular increase in the problem of proper housing and unhygienic living conditions. These reasons have given rise to factors that cause pollution. 

Environmental pollution is of five basic types namely, Air, Water, Soil, and Noise pollution. 

Air Pollution: Air pollution is a major issue in today’s world. The smoke pouring out of factory chimneys and automobiles pollute the air that we breathe in. Gases like carbon dioxide, carbon monoxide, and sulphur dioxide are emitted with this smoke which mixes with air and causes great harm to the human body, flora, and fauna. The dry-farm waste, dry grass, leaves, and coal used as domestic fuels in our villages also produce harmful gases. Acid rain occurs due to an excess of sulphur dioxide in the air.

The Main Sources of Air Pollution are as Follows:  

Automobile pollution 

Industrial air pollution 

Burning garbage 

Brick kilns 

Indoor air pollution 

Decomposed animals and plants 

Radioactive elements

Water Pollution: Water pollution is one of the most serious environmental issues. The waste products from the growing industries and sewage water are not treated properly before disposing of the wastewater into the rivers and other water bodies, thus leading to water pollution. Agricultural processes with excess fertilizers and pesticides also pollute the water bodies. 

The Main Sources of Water Pollution as Follows:  

Marine commerce. 

Industrial effluents joining seas and oceans. 

Dumping of radioactive substances into seawater. 

Sewage is disposed of into the sea by rivers. 

Offshore oil rigs. 

Recreational activities. 

Agricultural pollutants are disposed of into the water bodies.

Soil or Land Pollution: Soil pollution or land pollution results from the deposition of solid waste, accumulation of biodegradable material, deposition of chemicals with poisonous chemical compositions, etc on the open land. Waste materials such as plastics, polythene, and bottles, cause land pollution and render the soil infertile. Moreover, the dumping of dead bodies of animals adds to this issue. Soil pollution causes several diseases in man and animals like Cholera, Dysentery, Typhoid, etc.

The Main Causes of Soil Pollution are as Follows:  

Industrial waste 

Urban commercial and domestic waste 

Chemical fertilizers 

Biomedical waste 

Noise Pollution: With an increasing population, urbanization, and industrialization, noise pollution is becoming a serious form of pollution affecting human life, health, and comfort in daily life. Horns of vehicles, loudspeakers, music systems, and industrial activities contribute to noise pollution. 

The Main Sources of Noise Pollution as Follows:  

The machines in the factories and industries produce whistling sounds, crushing noise, and thundering sounds. 

Loudspeakers, horns of vehicles. 

Blasting of rocks and earth, drilling tube wells, ventilation fans, and heavy earth-moving machinery at construction sites.

How Pollution Harms Health and Environment

The lives of people and other creatures are affected by environmental pollution, both directly and indirectly. For centuries, these living organisms have coexisted with humans on the planet. 

1. Effect on the Environment

Smog is formed when carbon and dust particles bind together in the air, causing respiratory problems, haze, and smoke. These are created by the combustion of fossil fuels in industrial and manufacturing facilities and vehicle combustion of carbon fumes. 

Furthermore, these factors impact the immune systems of birds, making them carriers of viruses and diseases. It also has an impact on the body's system and organs. 

2.  Land, Soil, and Food Effects 

The degradation of human organic and chemical waste harms the land and soil. It also releases chemicals into the land and water. Pesticides, fertilisers, soil erosion, and crop residues are the main causes of land and soil pollution. 

3. Effects on water 

Water is easily contaminated by any pollutant, whether it be human waste or factory chemical discharge. We also use this water for crop irrigation and drinking. They, too, get polluted as a result of infection. Furthermore, an animal dies as a result of drinking the same tainted water. 

Furthermore, approximately 80% of land-based pollutants such as chemical, industrial, and agricultural waste wind up in water bodies. 

Furthermore, because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly. 

4. Food Reaction

Crops and agricultural produce become poisonous as a result of contaminated soil and water. These crops are laced with chemical components from the start of their lives until harvest when they reach a mass level. Due to this, tainted food has an impact on our health and organs. 

5. Climate Change Impact 

Climate change is also a source of pollution in the environment. It also has an impact on the ecosystem's physical and biological components. 

Ozone depletion, greenhouse gas emissions, and global warming are all examples of environmental pollution. Because these water basins eventually link to the sea, they contaminate the sea's biodiversity indirectly. Furthermore, their consequences may be fatal for future generations. The unpredictably cold and hot climate impacts the earth’s natural system. 

Furthermore, earthquakes, starvation, smog, carbon particles, shallow rain or snow, thunderstorms, volcanic eruptions, and avalanches are all caused by climate change, caused entirely by environmental pollution.

How to Minimise Environmental Pollution? 

To minimise this issue, some preventive measures need to be taken. 

Principle of 3R’s: To save the environment, use the principle of 3 R’s; Reuse, Reduce and Recycle. 

Reuse products again and again. Instead of throwing away things after one use, find a way to use them again.  Reduce the generation of waste products.  

Recycle: Paper, plastics, glass, and electronic items can be processed into new products while using fewer natural resources and lesser energy. 

To prevent and control air pollution, better-designed equipment, and smokeless fuels should be used in homes and industries. More and more trees should be planted to balance the ecosystem and control greenhouse effects. 

Noise pollution can be minimised by better design and proper maintenance of vehicles. Industrial noise can be reduced by soundproofing equipment like generators, etc.  

To control soil pollution, we must stop the usage of plastic. Sewage should be treated properly before using it as fertilizers and as landfills. Encourage organic farming as this process involves the use of biological materials and avoiding synthetic substances to maintain soil fertility and ecological balance. 

Several measures can be adopted to control water pollution. Some of them are water consumption and usage that can be minimized by altering the techniques involved. Water should be reused with treatment. 

The melting icebergs in Antarctica resulted in rising sea levels due to the world's environmental pollution, which had become a serious problem due to global warming, which had become a significant concern. Rising carbon pollution poses a risk for causing natural disasters such as earthquakes, cyclones, and other natural disasters. 

The Hiroshima-Nagasaki and Chernobyl disasters in Russia have irreversibly harmed humanity. Different countries around the world are responding to these calamities in the most effective way possible. 

Different countries around the world are responding to these calamities in the most effective way possible. More public awareness campaigns are being established to educate people about the hazards of pollution and the importance of protecting our environment. Greener lifestyles are becoming more popular; for example, energy-efficient lighting, new climate-friendly autos, and the usage of wind and solar power are just a few examples. 

Governments emphasise the need to plant more trees, minimise the use of plastics, improve natural waste recovery, and reduce pesticide use. This ecological way of living has helped humanity save other creatures from extinction while making the Earth a greener and safer ecology. 

 Conclusion

It is the responsibility of every individual to save our planet from these environmental contamination agents. If preventive measures are not taken then our future generation will have to face major repercussions. The government is also taking steps to create public awareness. Every individual should be involved in helping to reduce and control pollution.

Soil pollution surpasses climate change as top threat to underground biodiversity, study finds

by James Ashworth, Natural History Museum

Earthworms, insects and mites are all at risk from soil pollution, and scientists are worried that we know very little about the damage it's causing.

New research published in the journal iScience found that soil pollution was the leading cause of declines among organisms living underground. The finding has surprised scientists, who expected farming intensification and climate change to have much greater impacts.

Dr. Victoria Burton, a co-author of the new research based at the Natural History Museum, says that the findings are "concerning."

"Above ground, land use, climate change and invasive species have the greatest impact on biodiversity, so we assumed that this would be similar below ground," Victoria says. "Our results show, however, that this isn't the case."

"Instead, we found that pesticide and heavy metal pollution caused the most damage to soil biodiversity. This is worrying, as there hasn't been a lot of research into the impacts of soil pollution, so its effects might be more widespread than we know."

"Amid concern over soil degradation , we need to investigate what impacts other sources of pollution, such as microplastics, hydrocarbons and persistent chemicals, are having on the life beneath our feet."

The secret life of soils

Compared to life above ground, what's living in soils is relatively unknown. This is because, in addition to the difficulty in finding the organisms that live down there, soil is actually made up of multiple habitats all sitting on top of each other.

"Soil isn't just a homogenous lump of dirt," Victoria says. "It's a complex environment containing many different structures, nutrients and minerals. While the majority of life is found within 10 centimeters of the surface, some organisms can live much deeper ."

"But with so few specialists who can identify subterranean organisms, we know much less about life below than above ground."

This means that when it comes to finding out how soil communities are faring, there are a lot of open questions. While it's known that habitat destruction and persecution are some of the biggest impacts on aboveground biodiversity, only a few studies have tried to tackle their subterranean equivalents.

To try and account for this in their new research, the team performed what is known as a meta-analysis. This is where scientists take data from many existing studies and re-analyze them to answer new questions that the original research didn't focus on.

For this meta-analysis , Victoria and the rest of her team reused the data of more than 600 studies, including thousands of different datapoints, to see what impact humans were having on the health of soils globally.

Digging into soil research

Based on their results, wildlife above and below ground generally respond very differently to the same issues.

While the loss of a forest above ground might be devastating to the plants and animals that live there, the researchers' predictions that subterranean organisms would also be affected weren't proven. Instead, it seemed that the soil provided a buffer, helping its organisms to be more resilient to certain changes.

"Soils can store moisture and nutrients, which can help life living underground to withstand changes, at least in the short term," Victoria explains. "For instance, while climate change is affecting more and more species on the surface, its underground impacts appear to be limited for now."

"However, the effect of these impacts in the long-term is less well-known, meaning this buffering effect may only provide temporary relief for soil communities."

While the majority of the changes, like rising temperatures or chemical pollution, were negative for soil biodiversity, there were a few positives. The most important was the use of organic fertilizers and mulch, which introduces more carbon into the soil. This is especially beneficial for earthworms, which feed on the nutrients and cycle them in the soil.

Though this study has provided a deeper insight into the changes affecting soils, it's still barely scratched the surface. The team hope that future research will focus on how the interactions between factors like climate change and pollution, might enhance or limit their joint impacts

They also hope to get more people looking into soils. Victoria is keen to inspire the next generation of researchers while working with students as part of the National Education Nature Park, which is being led by the Natural History Museum.

"I'm excited to include soil biodiversity work within the National Education Nature Park," Victoria says. "It's a good opportunity to get young people excited about the life under their feet, and to get them interested in the life cycles of animals like craneflies and beetles which they might not know about."

"It's not just an opportunity to inspire them, but to do some important science that is currently being overlooked."

What is Plastic Pollution?

The accumulation of plastic substances and objects in our natural environment, like waterbodies, soil, etc. is known as plastic pollution. This pollution hurts the natural environment, our resources, and even on animals around us. According to a UN report, more than 100 million marine animals die every year due to plastic waste alone. Some of the common plastic wastes are cigarette butts, food wrappers, plastic bottles, plastic grocery bags, plastic straws, etc. 

Also Read: Types of Water Pollution

Causes of Plastic Pollution

Several causes can be cited as reasons for plastic pollution. It is our improper disposal and management of plastic materials that causes plastic pollution. Plastic is often called ‘unnatural’ as it is created by humans and negatively affects the environment. Plastic is cheap and its elements are in abundance. 

1. Single Use Plastic

It is the major cause of plastic pollution. Most of the plastic produced is used only once. Hence, named single-use plastic. The billions of plastic bags, bottles, food packaging and trays produced end up in landfills and water bodies. Even if we try our best to stop this single-use plastic, it will still end up in the same place. 

2. Lack of Recycling Infrastructure

In developing and underdeveloped countries, there is a lack of plastic recycling infrastructure, which threatens the environment. These countries lack the necessary infrastructure for plastic waste disposal, which results in landfills and water pollution. 

3. Improper Disposal

Improper disposal of plastic waste affects our food chain. Inadequate waste management and improper disposal of plastic items are major contributors to plastic pollution. Littering, dumping plastics in landfills, and improper disposal practices can result in plastic entering water bodies, soil, and the air.

5. Overconsumption of Plastic Products

Since its invention, plastic demand has always reached a new peak, driven by factors like population growth and consumer preferences, leading to higher production and disposal of plastics. This contributes to the accumulation of plastic waste in various ecosystems.

6. Inadequate Regulations

Not everybody considers plastic a threat to the environment. That’s why, there are weak or insufficient regulations on the production, use, and disposal of plastic products. Lack of enforcement and oversight allows for improper disposal and management practices.

Consequences of Plastic Pollution

Our environment is not the only victim of plastic pollution. Our ecosystems, wildlife and our health are also affected by plastic waste. Plastic chokes marine wildlife, killing millions of marine animals every year. Plastic production is energy-intensive as the machines used require a significant amount of energy.

1. Water Pollution

Every year, around 14 million tonnes of plastic waste ends up in our oceans, damaging the marine environment and animals. The accumulation of plastic waste in water bodies can have long-term ecological consequences.

2. Soil Contamination

Improper disposal of plastic waste results in soil contamination. Plastics release harmful chemicals as they break down, affecting soil quality and potentially harming plants, animals, and microorganisms.

3. Harm to Wildlife

Domestic animals are often fed food entangled in plastic items. In India, a large number of cows and buffalos die as most people often have their food wrapped in plastic bags. The ingestion of plastic can lead to internal injuries, blockages, malnutrition, and death. Marine animals, in particular, are at risk as they can easily ingest or become entangled in plastic debris.

4. Microplastic Contamination

Although plastic takes hundreds of years to decompose, the larger plastic items break down into smaller particles called microplastics. Microplastics can contaminate water bodies, soil, and air, posing risks to aquatic and terrestrial ecosystems. They can also enter the food chain, potentially affecting human health.

5. Disruption of Ecosystem

Plastic pollution disrupts ecosystems by affecting the balance of various species and their interactions. The presence of plastic debris in natural habitats can lead to changes in biodiversity, nutrient cycles, and ecosystem function. 

6. Risk to Human Health

Microplastics and the chemicals associated with plastics can enter the human food chain, primarily through the consumption of contaminated seafood and other food items. 

How to Beat Plastic Pollution?

Remember the 3Rs: Reduce, Reuse, and Recycle strategy? Here’s a little different approach introduced by the United Nations Environment Protocol (UNEP): Reuse, Recycle, and Reorient. Through this approach, the UNEP has planned to reduce plastic waste by 80% in the next two decades. 

We as plastic producers and consumers must take environmentally friendly actions and effectively implement this approach in our daily lives. 

• Firstly, we must eliminate unnecessary plastic, such as plastic packaging, reusing refillable water bottles, and every single-use plastic item. 
• Reducing plastic production will be the next step. We must advocate and support policies that regulate the plastic production, use, and disposal of plastics. Encouraging local representatives can greatly reduce overall plastic production and promote anti-plastic pollution measures
• Promoting and implementing recycling programs and guidelines will help reduce the overall production of plastic waste. It can be done by practising the separation of recyclables from non-recyclables and ensuring their proper disposal.
• Identification of which plastic item is useful and which is not must be done. Recycling is a great way to beat plastic pollution, but it alone cannot achieve the desired goals. 
• Avoiding microplastics can help in combating plastic pollution. We must choose personal care products that do not contain microbeads. The plastic clothes are made of synthetic fabrics, which shed microfibers during washing.

To eliminate plastic pollution, we must unite as one and take immediate action. We only have one home and we must do everything in our power to save it from such harmful events.

Ans: The accumulation of plastic substances and objects in our natural environment, like waterbodies, soil, etc. is known as plastic pollution. This pollution hurts the natural environment, our resources, and even on animals around us.

Ans: Plastic is everywhere. From our clean bedrooms to large ocean bodies, our life is surrounded by plastic. Did you know that the world annually produces around 35 crore tonnes of plastic waste? In the modern world, plastic has become one of the major sources of pollution. Plastic is a non-biodegradable component, which takes hundreds of years to decompose. Most of the used plastic ends up in landfills, which releases toxic chemicals into the soil and water. The burning of plastic causes air pollution, as it releases volatile organic compounds. 

Ans: Improper disposal of plastic waste results in soil contamination. Every year, around 14 million tonnes of plastic waste ends up in our oceans, damaging the marine environment and animals. In developing and underdeveloped countries, there is a lack of plastic recycling infrastructure, which threatens the environment. Plastic pollution disrupts ecosystems by affecting the balance of various species and their interactions. Microplastics and the chemicals associated with plastics can enter the human food chain, primarily through the consumption of contaminated seafood and other food items.

The world is pumping out 57 million tons of plastic pollution a year

A new study finds that every year people create 57 million tons of plastic pollution. The material ends up everywhere, from the deepest oceans to the highest peak to inside people’s bodies. More than two-thirds of it is in the Global South. (AP Video: Teresa de Miguel)

The world creates 57 million tons of plastic pollution every year and spreads it from the deepest oceans to the highest mountaintop to the inside of people’s bodies, according to a new study that also said more than two-thirds of it comes from the Global South.

It’s enough pollution each year — about 52 million metric tons — to fill New York City’s Central Park with plastic waste as high as the Empire State Building, according to researchers at the University of Leeds in the United Kingdom. They examined waste produced on the local level at more than 50,000 cities and towns across the world for a study in Wednesday’s journal Nature.

The study examined plastic that goes into the open environment, not plastic that goes into landfills or is properly burned. For 15% of the world’s population, government fails to collect and dispose of waste, the study’s authors said — a big reason Southeast Asia and Sub-Saharan Africa produce the most plastic waste. That includes 255 million people in India, the study said.

Lagos, Nigeria, emitted the most plastic pollution of any city, according to study author Costas Velis, a Leeds environmental engineering professor. The other biggest plastic polluting cities are New Delhi; Luanda, Angola; Karachi, Pakistan and Al Qahirah, Egypt.

India leads the world in generating plastic pollution, producing 10.2 million tons a year (9.3 million metric tons), far more than double the next big-polluting nations, Nigeria and Indonesia. China, often villainized for pollution, ranks fourth but is making tremendous strides in reducing waste, Velis said. Other top plastic polluters are Pakistan, Bangladesh, Russia and Brazil. Those eight nations are responsible for more than half of the globe’s plastic pollution, according to the study’s data.

The United States ranks 90th in plastic pollution with more than 52,500 tons (47,600 metric tons) and the United Kingdom ranks 135th with nearly 5,100 tons (4,600 metric tons), according to the study.

In 2022, most of the world’s nations agreed to make the first legally binding treaty on plastics pollution, including in the oceans. Final treaty negotiations take place in South Korea in November.

The study used artificial intelligence to concentrate on plastics that were improperly burned — about 57% of the pollution — or just dumped. In both cases incredibly tiny microplastics, or nanoplastics, are what turn the problem from a visual annoyance at beaches and a marine life problem to a human health threat, Velis said.

Several studies this year have looked at how prevalent microplastics are in our drinking water and in people’s tissue, such as hearts , brains and testicles , with doctors and scientists still not quite sure what it means in terms of human health threats.

“The big time bomb of microplastics are these microplastics released in the Global South mainly,” Velis said. “We already have a huge dispersal problem. They are in the most remote places ... the peaks of Everest , in the Mariana Trench in the ocean, in what we breathe and what we eat and what we drink.”

He called it “everybody’s problem” and one that will haunt future generations.

“We shouldn’t put the blame, any blame, on the Global South,” Velis said. “And we shouldn’t praise ourselves about what we do in the Global North in any way.”

It’s just a lack of resources and ability of government to provide the necessary services to citizens, Velis said.

Outside experts worried that the study’s focus on pollution, rather than overall production, lets the plastics industry off the hook. Making plastics emits large amounts of greenhouse gas that contribute to climate change .

“These guys have defined plastic pollution in a much narrower way, as really just macroplastics that are emitted into the environment after the consumer, and it risks us losing our focus on the upstream and saying, hey now all we need to do is manage the waste better,” said Neil Tangri, senior director of science and policy at GAIA, a global network of advocacy organizations working on zero waste and environmental justice initiatives. “It’s necessary but it’s not the whole story.”

Theresa Karlsson, science and technical advisor to International Pollutants Elimination Network, another coalition of advocacy groups on environment, health and waste issues, called the volume of pollution identified by the study “alarming” and said it shows the amount of plastics being produced today is “unmanageable.”

But she said the study misses the significance of the global trade in plastic waste that has rich countries sending it to poor ones. The study said plastic waste trade is decreasing, with China banning waste imports. But Karlsson said overall waste trade is actually increasing and likely plastics with it. She cited EU waste exports going from 110,000 tons (100,000 metric tons) in 2004 to 1.4 million tons (1.3 million metric tons) in 2021.

Velis said the amount of plastic waste traded is small. Kara Lavender Law, an oceanography professor at the Sea Education Association who wasn’t involved in the study, agreed, based on U.S. plastic waste trends. She said this was otherwise one of the more comprehensive studies on plastic waste.

Officials in the plastics industry praised the study.

“This study underscores that uncollected and unmanaged plastic waste is the largest contributor to plastic pollution and that prioritizing adequate waste management is critical to ending plastic pollution,” Chris Jahn, council secretary of the International Council on Chemical Associations, said in a statement. In treaty negotiations, the industry opposes a cap on plastic production.

The United Nations projects that plastics production is likely to rise from about 440 million tons (400 million metric tons) a year to more than 1,200 million tons (1,100 million metric tons, saying “our planet is choking in plastic.”

Negotiations for a global treaty on plastic pollution 1 will shape future policies on plastics production, use and waste management. Its parties will benefit from a high-resolution baseline of waste flows and plastic emission sources to enable identification of pollution hotspots and their causes 2 . Nationally aggregated waste management data can be distributed to smaller scales to identify generalized points of plastic accumulation and source phenomena 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 . However, it is challenging to use this type of spatial allocation to assess the conditions under which emissions take place 12 , 13 . Here we develop a global macroplastic pollution emissions inventory by combining conceptual modelling of emission mechanisms with measurable activity data. We define emissions as materials that have moved from the managed or mismanaged system (controlled or contained state) to the unmanaged system (uncontrolled or uncontained state—the environment). Using machine learning and probabilistic material flow analysis, we identify emission hotspots across 50,702 municipalities worldwide from five land-based plastic waste emission sources. We estimate global plastic waste emissions at 52.1 [48.3–56.3] million metric tonnes (Mt) per year, with approximately 57% wt. and 43% wt. open burned and unburned debris, respectively. Littering is the largest emission source in the Global North, whereas uncollected waste is the dominant emissions source across the Global South. We suggest that our findings can help inform treaty negotiations and develop national and sub-national waste management action plans and source inventories.

Plastic pollution is a global challenge requiring immediate action owing its environmental persistence and negative impact on ecosystems 14 , infrastructure 15 , society and the economy 16 . The importance of this burgeoning issue has recently been recognized by the ratification of a United Nations draft resolution to create an internationally legally binding instrument to end plastic pollution 1 , hereafter the ‘Plastics Treaty’. A global plastic pollution emissions inventory has been suggested as being critical to the success of the Plastics Treaty 17 and such inventories have already been applied in the climate change field 18 and as early evidence for a global legally binding agreement on mercury 19 , 20 —eventually the Minamata Convention 21 .

Previous efforts to model global plastic waste emissions and movement through the environment have demonstrated the scale of the issue, highlighting large macroplastic emissions from countries with extensive coastlines, large populations and insufficient waste management 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 . Yet there is a growing understanding that a much higher (sub-national) resolution is required, which identifies plastic pollution hotspots and accounts for specific local solid waste management, behavioural, cultural and socio-economic conditions 12 , 17 . We believe that the very concept of ‘emissions’ also requires clarification, owing to the complexity of the phenomena ( Methods and Extended Data Fig. 1 ). We use it here for clarity rather than the loosely defined terms of ‘leakage’ and ‘mismanaged waste’ described elsewhere 22 and we deliberately avoid the term ‘release’ suggested by the United Nations Economic Commission for Europe (UNECE) 23 , which could imply deliberate activity. We define plastic emissions as material that has moved from the managed or mismanaged systems (in which waste is subject to a form of control, however basic; contained state) to the unmanaged system (the environment; uncontained state) with no control. We further classify emissions according to two categories: (1) debris (physical particles >5 mm) and (2) open burning (mass combusted in open uncontrolled fires). For clarification, open burning emissions relate to the mass of material that is subjected to the practice, rather than the gaseous, liquid or solid matter emitted by the process. Further definitions and scope are in Supplementary Information Section S.2 .

Mapping and quantification of plastic waste material flows is hindered by the lack of sufficiently detailed and up-to-date records of waste management practices and quantities at a local level 24 , which prevents the complete assessment of emissions from human systems 25 . Although coordinated work is underway to remedy this data paucity 24 , a measurable baseline is urgently required to inform Plastics Treaty obligations 17 . As with greenhouse gas 18 or mercury 19 , 20 emissions inventories, this baseline would enable a more rational distribution of overseas development assistance, empower policymakers with scarce resources to develop evidence-based specialized national and sub-national strategies, action plans and targets 25 , and create a strong evidential basis for the reorganization of material systems that have been the focus of Plastics Treaty proposals 26 and negotiations 27 . Therefore, we created a macroplastic emissions inventory using a new methodology to quantify emissions for 50,702 municipality-level administrations from five land-based sources: (1) uncollected waste; (2) littering; (3) collection system; (4) uncontrolled disposal; and (5) rejects from sorting and reprocessing (Fig. 1 ). Unmeasured data were predicted using machine learning and flows were mapped using probabilistic material flow analysis (MFA) for the year 2020. See  Methods and Supplementary Information for detailed methodology.

Key plastic pollution sources and generalized waste management and circular economy flows are shown in this explanatory framework. Detailed materials and methods are available in the  Supplementary Information .

Global emissions of plastic waste

We estimate that 52.1 Mt year −1  [48.3–56.3] of macroplastic waste were emitted into the unmanaged system in 2020, representing 21% (wt.) of all the municipal plastic waste generated (251.7 Mt year −1  [233.1–272.4]) globally (statistics reported are the arithmetic mean of all iterations—simulation runs; the 5th and 95th percentiles are in square brackets). Approximately 43% (wt.) (22.2 Mt year −1  [20.6–24.0]) is unburned ‘debris’, meaning that it is no longer subject to any form of management or direct control and is at risk of transport across land and into the aquatic environment.

Most plastic pollution models do not report emissions in a way that is comparable with the present work, instead reporting emissions to ‘the aquatic environment’ 3 , ‘aquatic ecosystems’ 6 , ‘the ocean’ 8 , 28 , ‘mismanaged plastic waste’ 5 and ‘riverine outflows’ 29 . However, two studies report comparable data. Ryberg et al. 11 estimated macroplastic debris emissions to the environment at 6.2 Mt year −1 (confidence interval (CI): 2.0–20.4) in 2015. The upper end of the CI is within the range of our 5th percentile for debris emissions but the central estimate is approximately 3.5 times lower than our mean. The categories reported by Ryberg et al. 11 include sea-based, industrial and construction sources, which are all outside the scope of our model. Removing these would reduce their central estimate to 4.9 Mt year −1 , 4.5 times lower than our mean estimate. The sum of ‘terrestrial’ and ‘aquatic’ emissions estimated by Lau et al. 9 for 2016 was 29 Mt (95% CI: 22–39). This estimate includes microplastics and material emitted at sea but is otherwise congruent with our debris emissions category. Although the average reported by Lau et al. 9 is approximately 23% higher than our mean estimate, the lower CI is approximately the same as our mean debris emissions.

Our model improves on earlier works and provides new information in five ways: (1) in this model, we used a bottom-up approach rather than regional 10 and archetypal 9 averages distributed to finer resolution (top-down approach); (2) our finer resolution accounts for spatial heterogeneity in sub-national waste management data; (3) we modelled emissions from five separate downstream sources rather than the single homogenous source used in other models 3 , 4 , 5 , 6 , 7 , 8 , 28 —‘mismanaged (plastic) waste’ 22 , an umbrella term that encompasses a range of insufficiencies in waste management 12 ; (4) our definition of ‘emission’ includes waste that escapes from ‘dumpsites’ 24 (defined in Methods ) but excludes that retained within them because it is mostly buried beneath the waste mass 30 and poses a low risk of being blown or washed into the unmanaged system 31 . Only the ‘working face’ of these sites contains material at risk of transmission through the action of wind and surface water runoff 32 (Supplementary Information Section S.8.9 ). Conversely, it is self-evident that waste that is uncollected, scattered on land or accumulated in smaller ‘informal dumps’ has a much higher probability of being mobilized and transported across the terrestrial surface and into the aquatic environment; and 5) We account for the open burning of waste (Supplementary Information Section S.8.11 ), which is not specifically considered in most plastic pollution models 3 , 4 , 5 , 6 , 7 , 8 , 11 , 28 and which our results indicate contributes to 57% (29.9 Mt year −1  [27.6–32.4]) of all plastic waste emitted, resulting in widespread risk to human health and the environment 33 . As far as we are aware, only Lau et al. 9 report a comparable estimate of open burning of municipal solid waste plastic of 49 Mt year −1 (95% CI: 40–60) for 2016, two-thirds more than our estimate. The reason for this difference is the method of calculation. Whereas Lau et al. 9 used emission factors derived from expert assumptions published by the Intergovernmental Panel on Climate Change (IPCC) 18 and extrapolated from Wiedinmyer et al. 34 , our study uses census and survey activity data from 44 countries (Supplementary Information Section S.8.11 ).

Plastic emission hotspots outlook

On an absolute basis, we find that plastic pollution emissions are highest across countries in Southern Asia, Sub-Saharan Africa and South-eastern Asia (Fig. 2a–c ), with the largest amount (9.3 Mt year −1  [6.5–12.7]) emitted by India, equivalent to nearly one-fifth of global plastic emissions. In contrast to previous plastic pollution models that positioned China as the world’s highest plastic polluter 5 , 8 , it is ranked fourth in our results, with emissions of 2.8 Mt year −1  [2.1–3.7], less than Nigeria (3.5 Mt year −1  [2.6–4.6]) and Indonesia (3.4 Mt year −1  [2.5–4.3]). This lower contribution to plastic emissions from China reflects our use of more up-to-date data 35 that shows its substantial progress in adopting waste incineration and controlled landfill 36 . Conversely, India reports that its dumpsites (uncontrolled land disposal) outnumber sanitary landfills by 10:1 (ref.  37 ) and, despite the claim that there is a national collection coverage of 95%, there is evidence that official statistics do not include rural areas, open burning of uncollected waste or waste recycled by the informal sector 38 . This means that India’s official waste generation rate (approximately 0.12 kilograms per capita per day (kg cap −1  day −1 )) is probably underestimated and waste collection overestimated. Our model corrects for flows missing in officially reported statistics, resulting in a waste generation rate for India of 0.54 kg cap −1  day −1  [0.39–0.73], which is similar to and between other comparable estimates 38 , 39 , 40 .

a , Mean macroplastic emissions by country. Inset illustrates mean municipal-level emissions for India, from which the national results are calculated. Box plots show distribution of probabilistic material flow analysis results for the three highest macroplastic emitting countries in each United Nations sub-region. Box plot statistics: lower and upper hinges correspond to the first and third quartiles and the central line is the median. Whiskers extend to the data point no further than 1.5 times the interquartile range from the hinge, with outlier values beyond this denoted as dots. b , Emissions by United Nations sub-region and settlement typology 54 . Two groups of United Nations sub-regions are merged for simplicity into ‘Rest of Europe’ (Northern Europe, Southern Europe, Western Europe) and ‘Oceania’ (Polynesia, Australia and New Zealand, Melanesia, Micronesia). c , Mean emissions by United Nations sub-region and emission type. d , Mean proportion of macroplastic emissions by plastic format for the income categories of HIC and low-income or middle-income countries (LMIC).

Our data for India indicate a collection coverage of 81% [80–82], meaning that nearly 53% (wt.) [51–56] of the country’s plastic waste emissions (30% wt. [29–32] debris and 23% wt. [22–25] open burning) come from the 255 [241–270] million people (18% [17–19] of the population) whose waste is uncollected. Most of the remaining emissions (38% wt. [36–40]) are as a result of open burning on dumpsites, in which fires are reported to be common 38 . Overall, we estimate that 56.8 Mt year −1  [40.0–77.7] of municipal solid waste is open burned in India, of which 5.8 Mt year −1  [4.1–7.9] is plastic. This is within the lower end of the ranges modelled by Chaudhary et al. 38 of 74.0 Mt year −1 (uncertainty: 30–92) and Sharma et al. 39 of 68 Mt year −1 (range: 45–105).

Open burning rather than intact items (debris) is the predominant emission type across most United Nations sub-regions, except for those which are predominantly in the Global North (Northern America, Northern Europe, Western Europe and Australia and New Zealand) and Sub-Saharan Africa, in which debris emissions (7.4 Mt year −1  [6.7–8.2]) are slightly higher than open burning emissions (5.9 Mt year −1  [5.2–6.6]) (Fig. 2c ). This result is driven by data that indicate lower levels of open burning in the rural areas of low-income countries (LICs), of which there are many in the Sub-Saharan Africa region (Supplementary Fig. S.24d,f ).

Approximately 69% (35.7 Mt year −1 ) of the world’s plastic waste emissions come from 20 countries, of which four are LICs, nine are lower middle-income countries (LMCs) and seven are upper middle-income countries (UMCs). Despite high-income countries (HICs) having higher plastic waste generation rates (0.17 kg cap −1  day −1  [0.15–0.20]), none are ranked in the top 90 polluters, because most have 100% collection coverage and controlled disposal. Furthermore, our modelling accounts for the mitigating impact of street sweeping activity on emissions, which is greater in HICs (Supplementary Information Section S.8.5 ). We acknowledge that we may have underestimated plastic waste emissions from some HICs because we deliberately excluded plastic waste exports from our analysis. As explained in Supplementary Information Section S.2 , plastic waste exports from the top ten Organisation for Economic Co-operation and Development (OECD) exporters to non-OECD countries and Turkey have substantially decreased from nearly 5.4 Mt year −1 in 2017 to less than 1.7 Mt year −1 in 2022 (ref.  41 ), contributing approximately 0.03 Mt year −1 of emissions. Although this might affect some individual country results, the overall effect would be negligible in comparison with other sources.

Countries in low-income and middle-income categories have much lower plastic waste generation (LICs: 0.04 kg cap −1  day −1 ; LMCs: 0.07 kg cap −1  day −1 ; UMCs: 0.10 kg cap −1  day −1 ). However, in contrast to HICs, a large proportion of it is either uncollected (LICs: 55% wt.; LMCs: 26% wt.; UMCs: 11% wt.) or disposed of in dumpsites (uncontrolled disposal) (LICs: 36% wt.; LMCs: 57% wt.; UMCs: 19% wt.). The nine countries that make up the Southern Asia region emit a similar amount of plastic waste (15.1 Mt year −1  [12.1–18.7]) to the 51 countries in Sub-Saharan Africa (13.3 Mt year −1  [12.0–14.7]) (Fig. 2b,c ), with Nigeria contributing to approximately one-quarter (3.5 Mt year −1  [2.7–4.6]) of the Sub-Saharan African burden. Urban areas (cities, towns and semi-densely populated areas) account for most emissions in all regions (Fig. 2b ) because of low rural populations (Supplementary Information Section  7.1 ) and much lower plastic waste generation. However, we acknowledge that notable data gaps on solid waste management in rural communities exist and future efforts to address plastic pollution must include these often overlooked communities 42 .

Flexible plastic debris has a higher probability of being emitted into the environment in the Global South compared with rigid debris (mean ratio 56:44), driven by its greater prevalence (waste composition) and its propensity for mobilization under the action of wind and surface water (Fig. 2d ). In the Global North (for example, Northern America), the opposite is true (mean ratio 33:67) because rigid plastics are more prevalent in the waste and because emissions are driven by littering rather than meteorological forcing.

Per-capita emission hotspots

The contrast between absolute plastic waste emissions from the Global North and the Global South is stark (Fig. 3a,c ). However, on a per-capita basis, insufficiencies in local and national waste management systems are more apparent (Extended Data Figs. 2 – 6 ). For example, China, the world’s fourth largest absolute emitter, is one of the least polluting UMCs, ranked 153 of all countries on a per-capita basis (1.97 kg cap −1  year −1  [1.48–2.61]), and India, the world’s largest absolute emitter, is ranked 127 on a per-capita basis (6.64 kg cap −1  year −1  [4.66–9.08]). Conversely, Russia, the world’s fifth largest emitter on an absolute basis, also has high emissions on a per-capita basis (11.71 kg cap −1  year −1  [7.80–16.17]) because it is reported to have very low levels of controlled disposal 43 , 44 . Many countries in Sub-Saharan Africa that show low absolute plastic emissions are hotspots on a per-capita basis (Extended Data Fig. 4 ). Given the anticipated population boom in the region 45 , it is conceivable that, with an average emission rate of 12.01 kg cap −1  year −1  [10.83–13.25], Sub-Saharan Africa will become the world’s largest absolute source of plastic pollution within the next few decades.

Black dots are individual country results in each income category. The lower and upper hinges of the box plots correspond to the first and third quartiles and the central line is the median. Whiskers extend to the data point no further than 1.5 times the interquartile range from the hinge.

Municipal-scale probability distributions indicate substantial uncertainty within municipalities for some of our model outputs (Fig. 3b ). For example, the 5th and 95th percentiles of plastic emissions are 0.77–11.87 kg cap −1  year −1 (median 3.62 kg cap −1  year −1 ) for Agra (India) and 0.11–4.72 kg cap −1  year −1 (median 0.34 kg cap −1  year −1 ) for Maracaibo (Venezuela). The large ranges within many municipalities and relatively high kurtosis, for example, Shenzhen (42.3) and Maracaibo (19.9), are a consequence of our conservative application of probability density functions for many of the model’s input data, which have propagated through to the results.

Despite the wide uncertainty within each municipality, there are very large differences between many of them, enough to differentiate the most challenging locations from the least (Fig. 3b ). For example, median plastic emissions for Hamburg (Germany) are estimated at 0.02 kg cap −1  year −1  [0.01–0.06] compared with Mogadishu (Somalia), which has almost 680 times more (13.63 kg cap −1  year −1  [4.05–36.70]). Such large differences demonstrate that substantial reductions in plastic emissions are feasible, reiterating the importance of measuring sound solid waste management activity data. Continuing efforts to gather more reliable municipal-scale information 24 for SDG indicator 11.6.1 will gradually improve the accuracy of our model. However, much more comprehensive measurement and monitoring is required to improve the accuracy of flows that are rarely measured and that have been populated here using our conceptual sub-models.

Sources of plastic emissions

Uncollected waste is the largest contributor to plastic pollution in the Global South, accounting for 68% (35.6 Mt year −1 ) of all plastic waste emissions and 85% (18.7 Mt year −1 ) of all debris emissions. On a per-capita basis, uncollected waste represents 69%, 66% and 80% (wt.) of emissions in UMCs, LMCs and LICs, respectively (Fig. 4b ). Approximately 56% (19.9 Mt year −1  [17.8–22.3]) of emissions from uncollected waste come from LMCs, in which the mean collection coverage is 74% [72–75] (Fig. 4a ). Uncollected waste in LMCs accounts for 38% of total global plastic emissions and 51% (11.3 Mt year −1 ) of debris emissions. As far as we are aware, none of the other global plastic pollution models 3 , 4 , 5 , 6 , 7 , 8 , 11 , 28 has explicitly highlighted uncollected waste as the main source of plastic pollution, instead grouping it in the ‘mismanaged waste’ category or, in one case 9 , together with disposal site debris emissions. Here we show that plastic waste emissions from uncontrolled land disposal sites (dumpsites), although important, contribute 25% (12.8 Mt year −1  [11.5–14.3]) of global plastic waste emissions, of which 98% (wt.) is open burned. This means that just 0.25 Mt year −1 is emitted from land disposal sites as debris, approximately 0.4% (wt.) of plastics deposited in uncontrolled disposal sites worldwide. This is substantially less than has been inferred elsewhere. For example, Lau et al. 9 estimated that between 1% and 1.5% of rigid plastics and 8% and 13% of flexible and multimaterial plastics deposited in uncontrolled disposal sites would reach the aquatic environment each year. The difference is that Lau et al. 9 used expert judgement to derive their transfer coefficients, whereas this work used a more detailed sub-model based on the surface area and runoff characteristics of dumpsites detailed in Supplementary Information Section S. 8.9 .

Shown by: a , absolute mass and income category; b , per capita and income category; c , absolute mass and United Nations sub-region; and d , per capita and United Nations sub-region. Absolute mass of emissions ( a , c ) has unit Mt year −1 , whereas per-capita emissions ( b , d ) has unit kg cap −1  year −1 . Two groups of United Nations sub-regions are merged for simplicity into ‘Rest of Europe’ (Northern Europe, Southern Europe, Western Europe) and ‘Oceania’ (Polynesia, Australia and New Zealand, Melanesia, Micronesia). LIC, low-income country; LMC, lower middle income country; UMC, upper middle income country; HIC, high-income country.

HICs contribute 0.3% (0.16 Mt year −1  [0.14–0.19]) of global plastic waste emissions. Among HICs, uncollected waste is the source of 21% [15–27] (0.03 Mt year −1  [0.02–0.05]) of plastic waste emissions, just 0.06% of the global emissions burden, largely because collection coverage is nearly 100%. The largest source of debris emissions in HICs is littering (see ‘Uncollected litter’ defined in Supplementary Table S.3 ), accounting for 53% of debris emissions and 49% (0.08 Mt year −1 , 0.06 kg cap year −1 ) of all plastic emissions in the Global North (Fig. 4a,b ). Of this, 0.03 Mt year −1 takes place in Northern America and 0.03 Mt year −1 in the Rest of Europe region (Fig. 4c ), representing 0.09 kg cap year −1 and 0.07 kg cap year −1 , respectively (Fig. 4d ). The behavioural nature of littering 46 contrasts with the underlying drivers of other emission sources, especially those in the Global South. This is because, although littering is negatively correlated with waste receptacle provision 47 , it is largely driven by the decisions of individuals 46 . By contrast, the 1.5 billion individuals whose waste is uncollected in the Global South have little choice but to self-manage it (defined in Supplementary Information Section S.4.1 ).

The mismanagement of rejects from plastics sorting and reprocessing (recycling system) in both the Global North and the Global South results in 1.0 Mt year −1  [0.9–1.1] of plastic waste emissions to the environment. These emissions have often been the focus of attention, particularly in relation to the transboundary trade (exports) in waste plastics 48 . However, here we show that the emissions burden from recycling macroplastic rejects is comparatively very small.

An inventory to support the treaty

The purpose of our study was to create a macroplastic pollution inventory method for baselining and monitoring emissions at the local scale, at which on-the-ground actions can be applied. Such an emissions inventory, explaining the mechanisms for emission from the waste management and societal systems, could form a basis for a more detailed and comprehensive assessment of possible interventions. Once macroplastics have entered the environment, they are technically and economically challenging to remove 49 and, over time, will inevitably fragment into innumerable microplastics 50 , making clean-up efforts even more challenging. Minimizing plastic pollution at source by preventing the emission event in the first place must be a priority of the Plastics Treaty 17 and our insight indicates that tackling uncollected waste would have a bigger impact than mitigating all other land-based macroplastic sources combined. Notably, we already have a large global workforce of informal recyclers, entrepreneurs who our model shows collect more than 49.8 Mt year −1  [45.1–54.9] of waste plastics annually, much of which would otherwise be mismanaged.

We suggest that interventions to reduce uncollected plastic waste would focus on upstream material reduction to reduce waste generation and/or substantial improvement of waste collection services and infrastructure, and our emissions inventory sets a detailed basis for this. As highlighted elsewhere 9 , 51 , mitigating plastic waste emissions will require a multisectoral approach that includes addressing insufficiencies across the lifecycle, including redesign of product systems, source reduction and improving recycling systems worldwide. The plausibility of timely and at-scale deployment of such interventions needs to be carefully reassessed in the context of our new results.

The large mass of waste that is burned in open uncontrolled fires has not formed a central part of discussions at Plastics Treaty negotiations 26 , 27 . Yet, according to our model, more plastic waste is burned than is emitted as debris worldwide, releasing a cocktail of potentially hazardous substances and climate forcing emissions, which may have a substantial impact on human health and ecological systems 33 . An unintended consequence of interventions to mitigate the release of debris could result in an increase in emissions from open burning and vice versa 52 . Therefore, we propose that the inclusion of this phenomenon is a critical component of the forthcoming negotiations: clearly, choosing between two main forms of plastic pollution should not be an option.

We acknowledge that there is a dearth of robust, quality-controlled and verifiable waste management activity data. We have tediously screened, assessed, harmonized and corrected relevant data, incorporating uncertainty using a probabilistic approach. We have designed a conceptual framework that allows the model’s input data and structure to be continuously updated. As more quality-controlled locally obtained measurements from across the waste and resources system become available, and our understanding of release mechanisms improves, the model’s precision and accuracy can be ameliorated.

As with international climate change agreements 53 , signatories to the Plastics Treaty will require a method to calculate and baseline their plastic waste emissions so that they can compare them with others. Our emissions inventory enables them to carry out these estimates at high resolution by conceptualizing the mechanisms of emission, providing insights into the nature, extent and causes of plastic pollution and, therefore, enabling development of evidence-based national and sub-national action plans to eliminate plastic in our environment.

We created a macroplastic emissions inventory using a new methodology to quantify emissions from land-based sources for 50,702 municipality-level administrations 55 (see  Supplementary Information for details on the method). We define plastic emissions as material that has moved from the managed or mismanaged systems (in which waste is subject to a form of control, however basic) to the unmanaged system (the environment) with no control. For example, open dumpsites, defined here as structures that contain concentrations of collected waste with only basic control to prevent its interaction with the environment, are a form of control, because most of the material buried beneath the waste mass is unlikely to undergo further movement into the environment.

Material was mapped through 81 downstream (after-use phase) processes to simulate the flow of municipal solid waste through globally diverse waste management systems (Fig. 1 and Supplementary Information Section  4 ). Emissions of land-based macroplastic debris (physical particles >5 mm) and open burning (combustion in open uncontrolled fires) from municipal solid waste (defined in Supplementary Information Section S.2 ) were quantified for flexible and rigid plastics (format). Activity data (the intensity of waste and resources recovery management activity) were obtained from four global 56 , 57 , 58 , 59 and two national 35 , 60 waste management databases. These were checked for errors, harmonized to a consistent basis and corrected if necessary, creating the first comprehensively quality controlled city-level solid waste management database with worldwide coverage (Supplementary Data  1 ). Our primary input data represent 12.2% of the 2015 global population, spanning each of the World Bank income categories (LICs: 12.0%; LMCs: 11.4%; UMCs: 13.5%; HICs: 11.2%). Further discussion on the representativeness of our input data is presented in Supplementary Information Section S.6.7 .

Quantile regression random forest models 61 predicted data for all global municipalities using national and sub-national socio-economic indicators. Waste management, circular economy and plastic waste emission characteristics, variables that are not commonly measured or reported, were estimated using data from the literature or through the creation of new conceptual models. These newly developed ‘sub-models’ (Supplementary Information Sections S.8.2 , S.8.3 , S.8.3.4 , S.8.5 , S.8.5.2 , S.8.8 , S.8.9 , S.8.11.1 and S.9.1.2 ) used data on human behaviour, material value, socio-economic development, population density and solid waste management performance, creating an explanatory framework through which to estimate unmeasured system characteristics. The use of ‘process-level sub-models’ to describe larger systems has recently been advocated for plastic pollution modelling 13 .

Probabilistic (Monte Carlo simulation) MFA mapped flows of municipal solid waste (5,000 iterations) throughout the system (Supplementary Information Section S.4 ), resulting in detailed information on municipal solid waste and plastic waste management for each global municipality (Supplementary Data  5 ). Emissions into the unmanaged system, defined here as uncontained waste that is no longer subject to any form of management or control, were estimated for five key sources: (1) uncollected waste; (2) littering; (3) collection system; (4) uncontrolled disposal; and (5) rejects from sorting and reprocessing (Extended Data Fig. 1 ). The probabilistic MFA used probability density functions from two sources: (1) the results of the machine learning predictions and (2) from the secondary data collection and processing step detailed in Supplementary Information Section S.8 . A full list of probability density functions used in our model is available in Supplementary Data  6 and the MFA equations are shown in Supplementary Data  2 .

These flows and their associated uncertainty were aggregated to the national scale (Supplementary Data  3 ) to align with reporting for SDG indicator 11.6.1 (ref.  24 ) and to the regional and global scales (Supplementary Data  4 ) to create a multiresolution global plastic emissions inventory (Fig. 1 and Extended Data Fig. 7 ). This inventory is the first-stage prerequisite for a second terrestrial transport model (not discussed further here), collectively named the ‘Spatio-temporal quantification of plastic pollution origins and transport’ model (SPOT). Although we acknowledge that upstream processes during the production, conversion and use phases result in a range of emissions from plastics, they are outside the scope of our modelling. We also exclude textiles, sea-based sources of plastic pollution and waste electrical and electronic equipment. To improve comprehension of proportionality, the results are reported as the mean of all iterations (simulation runs). Numbers in square brackets are the 5th and 95th percentiles of all iterations. As there are no datasets with which to validate our model outputs, we took the same approach as Lau et al. 9 and carried out global sensitivity analysis to assess the influence of the model inputs and structure on its results (Supplementary Information Section S.10 ).

We warn readers to consider the full uncertainty in our MFA results, particularly for municipal-scale outputs at which the ranges are generally much larger than national-scale or regional-scale aggregations. The origins of uncertainty in our model are discussed at length in Supplementary Information Section S.9.2.2 . We also explain in Supplementary Information Section S.9.1.1 a specific circumstance in which we decided not to quantify uncertainty for the uncontrolled disposal coefficient (tC3) owing to limitations of the quantile regression random forest predictive capability for that particular aspect of the system.

500 Words Essay on Nature and Pollution

As we stride into the 21st century, mankind is confronted with a paradox of its own making. The same technological advancements that have propelled us into an era of unprecedented prosperity have also spawned an insidious adversary: pollution. This essay explores the intricate relationship between nature and pollution, focusing on the delicate balance that must be maintained to ensure the survival of our planet.

The Harmony of Nature

Pollution disrupts the natural order in myriad ways. Air pollution, primarily from industrial emissions and vehicle exhaust, contributes to global warming and climate change. These changes in climate patterns can result in extreme weather events and shifts in habitat conditions, affecting species survival.

Water pollution, often from industrial waste and agricultural runoff, contaminates our rivers, lakes, and oceans. This not only endangers aquatic life but also affects land-dwelling species that rely on these water bodies for survival. Soil pollution, largely due to improper disposal of waste and excessive use of pesticides, can degrade soil quality, affecting agriculture and disrupting food chains.

The Human Factor

The path to reconciliation.

Reversing the damage caused by pollution requires a fundamental shift in our attitudes and behaviors. We need to transition from a linear economy, where we take, make, and dispose, to a circular one, where waste is minimized, and resources are reused and recycled.

Innovation and technology can play a pivotal role in this transition. Renewable energy sources, like solar and wind, can replace fossil fuels, reducing air pollution. Technological advancements in waste management can help reduce water and soil pollution.

The interplay between nature and pollution is a stark reminder of the consequences of our actions. As we continue to exploit nature, we must also bear the responsibility for preserving it. The balance between progress and preservation is delicate, but it is within our grasp. By embracing sustainability, innovation, and education, we can chart a course towards a future where nature and mankind can coexist harmoniously.

That’s it! I hope the essay helped you.

► What is Pollution?

Pollution has become a major concern today. Man has interfered too much with nature. As a result, the environment including air, water, soil, etc… has been polluted.

If the environment is polluted, all sorts of life- human, animal, and vegetation are affected directly or indirectly. It is the introduction of harmful substances or pollutants into the environment.

◉ Pollution Meaning

• Pollution is the term derived from the Latin word “Pollutus”, which means foul and dirty.
• Pollution simply means dirt, impurity, or damage to the element of environment.
• Meaning of Polluting is making something impure.
• Pollution is damaging the earth’s environment in many ways i.e. air and water pollution.

◉ Definition of Pollution

Pollution can be defined as the introduction of contaminants into an environment that causes instability, disorder, harm, or discomfort to the ecosystem i.e. physical systems or living organisms.

Pollution can take the form of chemical substances or energy, such as noise, heat, or light.

Pollution has been defined as the “adverse effect on the natural environment. including human, animal or plant life or a harmful substance that does not occur naturally, such as industrial and radioactive waste, or the concentration to harmful levels of naturally occurring substance such as Nitrate.” – Robinson M (1996, Ecological Principles and Environmental issues)

Environmental pollutant means any solid, liquid, or gaseous substances present in such concentration as may be or tend to be injurious to the environment. – Sec 2(b), Environment Protection Act 1986

Pollution is the addition of various materials as a result of human activities to the environment and usually exerts a harmful influence on the environment. – RTM Sutanmihardja

An environment is called polluted if it has several elements, including; (1) if a substance, organism, or other elements such as gas, light, or energy has been mixed into a particular resource or environment. (2) and therefore inhibit or interfere with the function or designation of these resources or the environment. – Otto Soemarwoto

► Types of Pollution

There are mainly 4 kinds of pollution that are as listed below;

• Air Pollution
• Water Pollution
• Soil Pollution

◉ 1. Air Pollution (Essay on Pollution)

Air Pollution is brought about by the smoke of industries, manufacturing plants, engine vehicles, smoking, and consuming waste. Air pollution influences our well-being, it causes hacking, asthma, and other lung illnesses.

Air pollution refers to any physical, chemical, or biological change in the air. Pollution is the contamination of air by harmful gases, dust, and smoke that affects plants, animals, and humans drastically. There is a sure level of gases present in the environment. An expansion or reduction in the arrangement of these gases is unsafe for endurance.

✔ Causes of Air Pollution

• Burning of fossils fuels
• Agriculture Activities

✔ Effects of Air Pollution

• Global warming
• Respiratory disorders
• Ozone layer depletion.

◉ 2. Water Pollution

It is said to occur when toxic pollutants and particulate matter are introduced into water bodies such as lakes, rivers, and seas. Their contaminants are generally introduced by human activities like improper sewage treatment and oil skills.

Water Pollution is the tainting of water bodies (like seas, oceans, lakes, waterways, springs, and groundwater) typically caused because of human exercise.

Water pollution is any change, minor or major in the physical, substance, or natural properties of water that ultimately prompts an unfavorable outcome for any living creature.

Drinking water also known as Potable Water, is viewed as protected enough for human and creature utilization.

✔ Sources / Causes of Water Pollution

• Homegrown Wast
• Modern effluents
• Bug sprays and pesticides
• Cleansers and Fertilizers

A portion of the water pollution is brought about by direct Sources, like plants, which squander the executive’s offices, treatment facilities, and so on, that straightforwardly deliver squander and risky results into the closest water source without treating them.

Circuitous sources incorporate contaminations that implant in the water bodies using groundwater or soil or using the climate through acidic rain.

◉ 3. Soil Pollution (Essay on Pollution)

It portrays the tainting of soil because of the presence of harmful substances like unreasonable utilization of manures and pesticides, deforestation, modern waste, and so on…Soil pollution is an element that is utilized for the decay of soil because of surface, mineral, or quality substance of soil is decreased.

Additionally, this upsets the natural equilibrium of the living beings dependent on the dirt. Also, there are antagonistic impacts of soil contamination on the development of plants.

Normally, soil contamination is caused because of the presence of man-made applications like the permeation of tainted surface water, pesticides, fuel unloading, oil unloading, and so on.

◉ 4. Noise Pollution (Essay on Pollution)

It is dangerous to life. It is said that 85 decibels cause deafness and other diseases. The common reason behind noise pollution is the sound that comes from industry, planes, and other sources that reach beyond the permissible limits.

Noise pollution is a type of pollution that has become destructive these days.

This pollution is expanding just and establishes a hazardous climate. Commotion contamination is the point at which the degree of noise increments more than the typical level.

Whenever how much clamor surpasses, it becomes risky for living creatures. Additionally, these undesirable sounds goal a few unsettling influences and establish an unevenness in the climate.

► How to Reduce Pollution?

It is a global problem. It is an aggregate issue and accordingly, it needs an aggregate way to deal with ending it.

We should focus on going green, planting more trees, and eliminating waste in nature. We need to save agriculture.

We should quit utilizing unnecessary synthetic compounds and so on in horticulture to save our water from being contaminated. The world ought not just to glance at the business.

Alongside it, we want to find some kind of harmony between modern advancement and the introduction of nature. The role of government, mass media, and civil society are necessary.

It refers to the contamination of the natural environment by various harmful substances, resulting in adverse effects on human health, wildlife, and the ecosystem as a whole. The sources of pollution are numerous and diverse, ranging from industrial activities and transportation to improper waste disposal and deforestation. Pollution knows no borders and affects all living organisms, making it a global menace that requires immediate attention and action.

One of the most prominent types of pollution is air pollution. The burning of fossil fuels in industries, vehicles, and power plants releases harmful gases like carbon dioxide, sulfur dioxide, and nitrogen oxides, contributing to the greenhouse effect and climate change. Additionally, particulate matter and toxic pollutants in the air pose severe health risks, leading to respiratory illnesses and cardiovascular diseases.

Water pollution is equally concerning. Industrial waste, agricultural runoff, and untreated sewage find their way into rivers, lakes, and oceans, contaminating the water supply. This not only endangers aquatic life but also impacts human communities that depend on these water sources for drinking, irrigation, and recreation. The growth of massive oceanic garbage patches highlights the detrimental impact of plastic waste on marine ecosystems.

Furthermore, soil pollution is an often overlooked yet critical aspect of environmental degradation. The excessive use of chemical fertilizers and pesticides in agriculture leads to soil degradation and the loss of fertile land. This, in turn, affects crop yields and the quality of food produced.

Noise pollution, caused mainly by urbanization and industrialization, has detrimental effects on human health and wildlife. Prolonged exposure to loud noise can result in hearing loss, stress, and sleep disturbances, while disrupting the natural communication and behavior of animals.

The consequences of pollution are far-reaching. It affects not only the environment but also the economy and society. Healthcare costs rise due to pollution-related illnesses, and industries suffer from regulations and clean-up efforts. Biodiversity loss and ecosystem degradation jeopardize the delicate balance of nature, posing significant challenges to food security and sustainable development.

Addressing pollution requires collective efforts at both individual and governmental levels. Implementing and enforcing stricter environmental regulations for industries, promoting clean and renewable energy sources, and investing in sustainable transportation are crucial steps to curb pollution. Recycling and waste management practices should be encouraged, and public awareness campaigns can help educate people about their roles in preserving the environment.

In conclusion, pollution is a grave threat that demands urgent action. To protect our planet and ensure a sustainable future, we must all come together and adopt environmentally responsible practices. By recognizing the impact of pollution and taking proactive steps, we can create a cleaner, healthier, and more vibrant world for generations to come.

Environmental Pollution Essay 100 words – Sample 1

Environmental pollution refers to the introduction of undesirable polluting substances into the environment. These substances are produced mainly due to human activities like transportation, industrialization and urbanization among others. There are even some natural factors that cause environmental pollution like volcanic eruption, storms etc., but their impact on the environment is temporary as well as negligible as compared to the human induced pollution.

Pollution poses a serious threat to the environment and also to the life and heath of humans, plants and animals. Any living species could only survive if the environment remains clean and pure, otherwise life on the planet would be really difficult and impossible to imagine.

Environmental Pollution Essay 150 words – Sample 2

Very often we hear the term environmental pollution while talking about harm human’s quest for progress is doing to the environment and what impacts it has on the health of humans and other species as well.

Pollution of the environment happens when our natural environment is disturbed by the introduction of unwanted and harmful substances known as pollutants. Many human activities like use of fossil fuels in the vehicles, dumping of industrial waste, cutting down trees and forests for urban settlements and large use of plastic are some of the main human induced causes of environmental pollution.

Causes of Polluiton

Environmental pollution leads to a series of undesirable outcomes like global warming, acid rain, species depletion, flood and famines among several other severe consequences. If we want the planet to be green and inhabited for millions of more years then it is very necessary that we should take all the necessary steps to prevent environmental pollution.

Environmental Pollution Essay 200 words – Sample 3

Environmental pollution is described as the introduction of external pollutants into the environment. Our natural environment consists of the air, forests, rivers, streams, land, soil, vegetation etc. If anything unwanted generated due to human activities enter this otherwise pristine environment, this phenomenon is termed as environmental pollution.

Some of the major human activities causing environmental pollution are industrialization, deforestation, urbanization, nuclear spills etc. Often the production industries are set up near the natural water sources as water is a major resource for several kinds of industrial works.

Water used as coolant and also used for purposes like cleaning, washing etc. But also the waste produced by industries dumped into the water bodies resulting in their pollution.

Water a precious natural resource and though, almost 70% of earth’s surface is covered with water, only 1% of it is actually fresh water and suitable for consumption. Industrial waste pollutes that 1% of extremely rare reserve of fresh water, which has actually taken hundreds of years to be build.

It is very necessary therefore to prevent any damage to the environment and natural resources caused by the human activities. Environmental pollution is a global threat and it must be prevented by making new laws and implementing them with full diligence.

Environmental Pollution Essay 250 words- Sample 3

The term environmental pollution used to describe the contamination of environment by external substances called pollutants. These pollutants generated due to human activities and could be in gaseous, solid or liquid state, depending on their respective process of generation.

Gaseous pollutants include gases like Carbon dioxide (CO 2 ), Carbon Monoxide (CO), Sulphur Dioxide (SO 2 ) generated due to the combustion of fossil fuels. These gases are toxic in nature and harmful to breathe in, when present in the atmosphere in large quantities.

Solid pollutants include industrial waste and waste from human settlements. They consists of all types of solid compounds like plastic, metal, wood, leaves, etc. Solid pollutants not only cause land and soil pollution but also reach our water bodies and pollute them.

Liquid pollutants on the other hand consist of oil and other petroleum products, chemicals, acids etc. The main source of liquid pollutants is petroleum and fuel production industries.

Environmental pollution has an adverse effect on the vital resources like air, water and plants as well as on the health and life of humans. Air pollutions causes respiratory ailments while the pollution of water bodies leads to water borne diseases. Soil pollution also causes contamination of soil affecting the crop production in that particular area.

There is an urgent need to control the environmental pollution by effectively controlling the production of pollutants by adopting more environment friendly policies. Use of more eco friendly fuel sources and proper collection and disposal of waste are some of the methods that could adopted to control environmental pollution.

• Pollution is a serious health concern for people around the world, including the children and adults. Nearly 10 million people worldwide are suffering due to pollution related issues and it is also responsible for the death of more than 2 million children under the age of 5.
• Water pollution in developed countries is chiefly due to industrial waste. Around 70% of industrial waste in developed countries dumped into water, making the lakes and rivers too polluted for any activity.
• Pollution of fresh drinking water is one of the main causes of loss of life throughout the world. Every year at least 250 million cases of water borne diseases reported, which subsequently causes 2 to 10 million deaths.
• A normal human being breathes in around 11,000 liters of air per day. Therefore, breathing polluted air causes severe lung diseases and people living in places with poor air quality are more susceptible to it.
• Motor vehicles are the main source of air pollution than anything else. An average car produces at least half a ton of carbon dioxide.

Though, the pollution affects the environment and the health of flora and fauna; it is the children who are more susceptible to it health hazards. We must take necessary steps to curb pollution in order to safeguard the health and future of our children.

Environmental Pollution Essay 350 words- Sample 5

Environmental Pollution refers to the introduction of external pollutants into the environment. These pollutants primarily generated from several human activities like transportation, industrialization etc. Environmental pollution has many effects on the environment. Some of the major effects of environmental pollution described below.

Major Effects of Pollution

• Global Warming

Global warming refers to the rise in average surface temperature of earth. The main reason of global warming is the greenhouse effect which in turn caused due to a large concentration of green house gases into the atmosphere. Gases like Carbon dioxide (CO 2 ), Water vapor (H 2 O), Methane (CH 4 ) and Nitrous Oxide (N 2 O) are green house gases and emitted mainly due to the fossil fuel combustion. Greenhouse gases help retain the sun’s heat into the atmosphere, consequently resulting in a rise in earth’s surface temperature.

Acid rain is another environmental degrading effect of pollution. It refers to a rain or a kind of precipitation that is acidic in nature with more concentration of Hydrogen ions, in other words the pH level of Acid Rain is low. It is very harmful to the plants, aquatic species and buildings also. The main human induced causes of acid rain are nitrogen and sulfur compounds generated due to activities like generation of electricity, meat production industries and transportation.

• Species Depletion

One of the most serious effects of environmental pollution is species depletion both on land and in water. Water pollution severely impacts the quality of water, making it toxic and harmful to live in for the aquatic animals like fishes and tortoise etc. They are highly sensitive to the pollution and often succumb to it. Land pollution and air pollution also causes the depletion of the species of flora and fauna respectively. Air pollution causes some serious respiratory ailments in humans as well as animals.

Pollution not only effects the environment, but it also threatens the very existence of life on earth. It has a large degrading effect on the environment and we must take necessary remedial measures for its prevention if we want our planet to stay healthy and green.

Environmental Pollution Essay 400 words Sample 6

Environmental pollution refers to the inclusion of unwanted toxic pollutants into the environment. These pollutants mainly generated due to several human activities and causes environment degradation. Different types of pollutants lead to different types of environmental pollution which we will discuss below.

Types of Environmental Pollution

Water Pollution

Water Pollution occurs when toxic substances like chemicals, plastic and other waste enters our water resources. The pollutants could include chemicals from agricultural runoff, industrial waste, urban sewage, oil spills by boats etc. Fresh water is very precious natural resource and must kept clean at any cost. As per an estimate provided by the Environment Protection Agency (EPA), 64% of lakes are not suitably clean for activities like fishing and swimming.

• Air Pollution

Air Pollution occurs when particles and other harmful gases generated due to human activities get mixed with the environmental air and causes its degradation. A main cause of the air pollution is the production and use of fossil fuels. The fossil fuel production industry produces harmful gases like SO 2 (Sulphur dioxide), CO 2 (Carbon dioxide) etc. These gases are toxic in nature and cause other serious complications like greenhouse effects and acid rain.

• Land/Soil Pollution

The main cause of land/soil pollution is urban waste and agricultural runoff. Urban waste consists of all type of degradable, and non degradable waste likes vegetables, waste food, plastic, hospital waste etc. In the absence of a proper waste collection and disposal mechanism, these wastes get disposed on land resulting in land pollution. Moreover, the use of chemical fertilizers in the agricultural industry causes the chemical pollutants to get absorbed in the soil, causing soil pollution.

• Noise Pollution

Noise pollution also known as sound pollution and caused when the noise level into the environment reaches up to dangerously high level so as to interfere with normal activities of humans and animals. Transportation vehicles, heavy machineries, aircrafts are the main sources of noise pollution. Noise level is measured in Decibel (dB) and the permissible limit of noise as described by the World Health Organization (WHO) is 50 dB. Though, in the areas of dense population, urban settlement and traffic it often reaches up to 98 dB, which is very harmful to the humans and animals.

There many types of pollution depending on the activities they generated from; nevertheless, the ability to deal with all of them lies only with humans. It required that we take immediate responsibility of our environment and also take necessary steps towards preventing its pollution.

Environmental Pollution Essay 500 words – Sample 7

Everything that surrounds us constitutes the environment. It is the condition in which humans, plants, animals and other creatures live and operate. Environmental Pollution on the other hand is the introduction of unwanted and often toxic substances in to the environment. These substances termed as pollutants and mainly produced due to human activities. In the following essay we will go through causes, effects and control of environmental pollution.

Causes of Environmental Pollution

Many causes of environmental pollution including oil spills, burning of fossil fuels, industrial waste, use of chemical fertilizers in agriculture, use of plastic etc. for instance, transportation industry relies on fuel like petrol and diesel that has derived formed due to anaerobic decomposition of buried dead organisms. The main pollutant gas emitted when fossil fuel burned in a transport vehicle are CO 2 (Carbon dioxide) and CO (Carbon Monoxide). Former is a potent greenhouse gas while the latter is toxic in nature.

Industrial waste generated in industries throughout world carelessly dumped in to environment due to lack of proper planning. It pollutes our water bodies, land and is also harmful to the health of human and other living species.

Effects of Environmental Pollution

Effects of Environmental Pollution are on number of factors including human health as well as survival and health of other living organisms, animals and plants.

Air pollution causes severe respiratory ailments in humans and animals alike. Water pollution renders water toxic and natural water resource unusable. It also causes depletion of aquatic species and flora and fauna that depends on it.

Above mentioned effects of environmental pollution, some more severe effects like global warming, floods and acid rain. Global warming caused due excess environmental concentration of gases like CO 2 (Carbon dioxide), CH 4 (Methane), N 2 O (Nitrous Oxide) and O 3 (Ozone). These gases primarily released due to human activities like transportation, industrialization etc.

Environmental Pollution Control

Pollution control refers to the controlling of emissions from human activities, into the environment. The waste products that generated by transportation, industrialization, and several other similar activities; leads to the degradation of the environment.

Pollution caused by these waste products could controlled by adapting to new environmental friendly norms for industries. And by allowing recycling or proper disposal of waste.

Methods like dust collection system and electrostatic precipitation can used to control air pollution; sewage treatment like sedimentation can used for treating industrial and urban waste.

Environmental pollution is one of the greatest threats to health of the planet. Ever growing human needs and man’s quest for progress is consistently degrading the atmosphere and its elements. An urgent need to take necessary action for controlling environment pollution caused due to human activities by taking remedial measures.

COSTA RICA'S LEADING ENGLISH LANGUAGE NEWSPAPER

Unions and Students March in San José for Education Funding

Costa rica joins global rejection of venezuelan vote, air pollution in san josé surpasses mexico city, raising alarm bells, costa rica proposes groundbreaking law to combat noise pollution, the forgotten helicopter: a glimpse into costa rica’s osa peninsula logging past.

In a shocking revelation, our capital city’s air quality has deteriorated to levels worse than those of Mexico City, long considered one of the most polluted urban areas in Latin America. This alarming news comes as the Defensoría de los Habitantes (Ombudsman’s Office) calls for urgent action to address the growing air pollution crisis in Costa Rica.

Recent data shows that the concentration of particulate matter (PM10) in San José’s air has reached a concerning 27.1 micrograms per cubic meter (µg/m³), significantly higher than Mexico City’s 21.7 µg/m³. These tiny particles, primarily produced by vehicle emissions, factories, and other human activities, pose serious health risks to our population.

The gravity of the situation is further underscored by an Organization for Economic Cooperation and Development report, which found that a staggering 88% of Ticos are exposed to harmful levels of air pollution. Defensora de los Habitantes, Angie Cruickshank, emphasized the need for collective action: “The air we breathe affects us all. We must unite across all sectors of society to strengthen public policies that protect our right to a healthy environment and prioritize public health.”

José Félix Rojas, an expert from the Universidad Nacional, pointed out that while Costa Rica has regulations for critical pollutants, there’s an urgent need for sustained funding for air quality monitoring and greater involvement from key stakeholders. “Our national challenge is to establish a comprehensive air quality management model and integrate local governments into this effort,” Rojas explained.

The impact of this pollution crisis extends beyond our capital. Ronald Flores, a public transportation specialist, highlighted how traffic congestion contributes to energy waste, air quality deterioration, and global warming through various emissions. He stressed that improving our public transportation system could significantly mitigate these issues.

As Ticos, we’re known for our commitment to environmental conservation. Now, we face a critical challenge in our own backyard. The Defensoría urges all Costa Ricans to join in the effort to combat air pollution, reminding us that clean air is essential for our health, our children’s future, and the preservation of our beloved país verde.
