Light Pollution

Learn about the effects of excess light coming from cities at night.

In most situations, light helps us see. But when it comes to looking at the night sky, light is actually a kind of pollution.

It hampers our view of some of life’s most spectacular sights: stars, planets, and even galaxies. “When I was a little boy, I loved the night sky,” recalls Robert Gent of the International Dark-Sky Association, an organization working to reduce light pollution.

“I remember looking up and the sky was filled with stars, and I asked, ‘How many are there? How far away are they? Can we visit them?’ I became an astronomer because I was amazed by their beauty,” he says. “Now in most big cities kids can’t see the stars like I did.”

Normally, about 2,500 individual stars are visible to the human eye without using any special equipment. But because of light pollution, you actually see just 200 to 300 from today’s suburbs, and fewer than a dozen from a typical city.

Only one in three Americans can see our own galaxy, the dazzling Milky Way, with the naked eye. Those people live far away from the lights of big cities, office buildings, and shopping malls.

Fortunately, there is a solution that is inexpensive and has benefits right away, says Gent. “If we shine lights down at the ground instead of up into the sky, and use lower brightness levels, we can save enormous amounts of energy and preserve the beauty of the night skies.”

Many cities and towns have passed laws limiting lights at night, making sure enough shine for safety without creating a lot of light pollution.

Light pollution affects more than our view of the heavens. Research shows that lots of nighttime light can harm wildlife.

Migrating birds sometimes fly over cities and become confused by the brightness, flying in circles until they drop from exhaustion. Sea turtles need dark beaches for nesting and won’t approach bright lights. Too much light at night may even affect human health; scientists are still learning more.

For all these reasons, researchers are working on ways to use lights only when and where they are truly needed. “Everyone deserves to look up at the infinite sky and wonder about the unbounded universe,” says Gent.

Boats, buildings, street lights, and even fireworks contribute to the light pollution in Victoria Harbor, Hong Kong. Light pollution can be detrimental to the health of people and animals in the area.

Most environmental pollution on Earth comes from humans and their inventions. Take, for example, the automobile or that miraculous human-made material, plastic . Today, automobile emissions are a major source of air pollution contributing to climate change, and plastics fill our ocean, creating a significant health hazard to marine animals.

And what about the electric lightbulb, thought to be one of the greatest human inventions of all time? Electric light can be a beautiful thing, guiding us home when the sun goes down, keeping us safe and making our homes cozy and bright. However, like carbon dioxide emissions and plastic , too much of a good thing has started to negatively impact the environment. Light pollution , the excessive or inappropriate use of outdoor artificial light, is affecting human health, wildlife behavior, and our ability to observe stars and other celestial objects.

That Earthly Sky Glow

Light pollution is a global issue. This became glaringly obvious when the World Atlas of Night Sky Brightness , a computer-generated map based on thousands of satellite photos, was published in 2016. Available online for viewing, the atlas shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East, and Asia are glowing with light, while only the most remote regions on Earth (Siberia, the Sahara, and the Amazon) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.

Sky glow is the brightening of the night sky, mostly over urban areas, due to the electric lights of cars, streetlamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.

People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers are particularly concerned with sky glow pollution as it reduces their ability to view celestial objects.

More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow. It sounds pretty, but sky glow caused by anthropogenic activities is one of the most pervasive forms of light pollution .

Is it Time to Get Up?

Artificial light can wreak havoc on natural body rhythms in both humans and animals. Nocturnal light interrupts sleep and confuses the circadian rhythm—the internal, twenty-four-hour clock that guides day and night activities and affects physiological processes in nearly all living organisms. One of these processes is the production of the hormone melatonin , which is released when it is dark and is inhibited when there is light present. An increased amount of light at night lowers melatonin production, which results in sleep deprivation, fatigue, headaches, stress, anxiety, and other health problems. Recent studies also show a connection between reduced melatonin levels and cancer. In fact, new scientific discoveries about the health effects of artificial light have convinced the American Medical Association (AMA) to support efforts to control light pollution and conduct research on the potential risks of exposure to light at night. Blue light, in particular, has been shown to reduce levels of melatonin in humans. Blue light is found in cell phones and other computer devices, as well as in light-emitting diodes (LEDs), the kinds of bulbs that have become popular at home and in industrial and city lighting due to their low cost and energy efficiency.

Animals are Lost and Confused, Too

Studies show that light pollution is also impacting animal behaviors, such as migration patterns , wake-sleep habits, and habitat formation. Because of light pollution , sea turtles and birds guided by moonlight during migration get confused, lose their way, and often die. Large numbers of insects, a primary food source for birds and other animals, are drawn to artificial lights and are instantly killed upon contact with light sources. Birds are also affected by this, and many cities have adopted a “Lights Out” program to turn off building lights during bird migration.

A study of blackbirds ( Turdus merula)  in Germany found that traffic noise and artificial night lighting causes birds in the city to become active earlier than birds in natural areas—waking and singing as much as five hours sooner than their country cousins. Even animals living under the sea may be affected by underwater artificial lighting. One study looked at how marine animals responded to brightly lit panels submerged under water off the coast of Wales. Fewer filter feeding animals, such as the sea squirt and sea bristle, made their homes near the lighted panels. This could mean that the light from oil rigs, passing ships, and harbors is altering marine ecosystems .

Even in places meant to provide protected natural habitats for wildlife, light pollution is making an impact. The National Park Service (NPS) has made maintaining a dark night sky a priority. The NPS Night Skies Team has been monitoring night sky brightness in some one hundred parks, and nearly every park showed at least some light pollution.

You Shouldn’t Need Sunglasses at Night

There are three other kinds of light pollution: glare, clutter, and light trespass. Glare is excessive brightness that can cause visual discomfort (for example, when driving). Clutter is bright, confusing, and excessive groupings of light sources (for example, Times Square in New York City, New York). Light trespass is when light extends into an area where it is not wanted or needed (like a streetlight illuminating a nearby bedroom window). Most outdoor lighting is poorly positioned, sending wasted electricity up into the sky.

Bring Back the Dark Sky

There are several organizations working to reduce light pollution. One of these is the U.S.-based International Dark Sky Association (IDA), formed in 1988 to preserve the natural night sky. IDA educates the public and certifies parks and other places that have worked to reduce their light emissions. In 2017, the IDA approved the first U.S. dark sky reserve. The massive Central Idaho Dark Sky Reserve, which clocks in at 3,667 square kilometers (1,416 square miles), joined eleven other dark sky reserves established around the world. As of December of 2018, IDA lists thirteen dark sky reserves on their site.

Stop Wasting Energy: Things We Can All Do

More people are taking action to reduce light pollution and bring back the natural night sky. Many states have adopted legislation to control outdoor lighting, and manufacturers have designed and produced high-efficiency light sources that save energy and reduce light pollution.

Individuals are urged to use outdoor lighting only when and where it is needed, to make sure outdoor lights are properly shielded and directing light down instead of up into the sky, and to close window blinds, shades, and curtains at night to keep light inside.

Many inventions have changed human life. But they have also caused pollution . One source of pollution you may not have considered is the electric light bulb.

As one of the greatest inventions of all time, it helps us in many ways. Yet light pollution , the excessive or inappropriate use of outdoor artificial light, affects human health, wildlife behavior and our ability to observe objects in the sky.

Where Light Pollution Happens

Light pollution is a global issue. This became glaringly obvious when a computer generated map called the World Atlas of Night Sky Brightness was published in 2016. The atlas is based on thousands of satellite photos and shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East and Asia glow with light, while only the most remote regions on Earth, such as Siberia, the Sahara Desert and the Amazon, are in total darkness.

Sky glow is the brightening of the night sky. It occurs mostly over urban areas due to the electric lights of cars, street lamps, offices, factories, outdoor advertising and buildings. These lights turn night into day for people who work and play long after sunset.

More than 80 percent of the world's population, and 99 percent of Americans and Europeans, live under sky glow. It is one of the most pervasive forms of light pollution . People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers are concerned about sky glow as it reduces their ability to view planets, stars, and other celestial objects.

Health Effects of Light Pollution

Beyond sky glow, constant exposure to light can impact health. Artificial light can ruin natural body rhythms in humans and animals. Nighttime light interrupts sleep and confuses the circadian rhythm, which is the body's internal clock that guides day and night activities and affects physiological processes.

One of these processes is the production of a hormone called melatonin , a chemical produced naturally by the body to help promote sleep. The body releases melatonin when it is dark and inhibits release when there is light. Increasing exposure to nighttime light lowers melatonin production. Consequently, this results in sleep deprivation, fatigue, headaches, stress, anxiety, and other health problems.

Blue light, in particular, reduces levels of melatonin in humans. It's used in cell phones, computer devices and light-emitting diodes (LEDs), the kinds of light bulbs that have become popular due to their low cost and energy efficiency.

Animals Are Affected Too

Studies show that light pollution also affects animal behaviors. Sea turtles and birds guided by moonlight during migration get confused by light pollution , lose their way and often die. Large numbers of insects, a primary food source for birds and other animals, are drawn to artificial lights and are instantly killed upon contact with light sources. A study of blackbirds in Germany found that traffic noise and artificial light causes birds in cities to become active earlier than birds in natural areas. Many cities have adopted a "Lights Out" program to turn off building lights, especially during bird migration.

Even animals living under the sea may be affected by underwater artificial lighting. One study in the United Kingdom found that fewer filter feeders make their homes near submerged bright lights. Filter feeders are marine animals that feed on small particles by sifting water through their bodies, such as mussels or oysters. This could mean that the light from oil rigs, passing ships and harbors alters marine ecosystems .

Light pollution is having an effect on places meant to provide protected natural habitats for wildlife. The National Park Service monitors night sky brightness in about 100 parks, and nearly every park shows at least some light pollution.

Addressing Light Pollution

There are several organizations working to reduce light pollution. One of these is the International Dark Sky Association (IDA).

  • Set up a piece of white paper so that it is equally illuminated by indirect natural light. Choose a place where the light is bright. The most important thing is that the paper is illuminated evenly. Choose a time and place during which it is unlikely there will be any changes in how much light is present.
  • Set up your digital camera so that the white paper fills the entire field of view. The distance from the camera to the paper is not important.
  • Put the camera in manual mode and make the following changes:
  • Adjust the focus so that the camera is focused on the white piece of paper. Once you set the focus, do not change it.
  • Set the camera’s sensitivity to ISO 200.
  • Set the aperture to f/2.8.
  • Set the image resolution to a low setting.
  • If your camera has a self-timer feature, set it so that the camera shutter opens a few seconds after you take a picture. This minimizes shake.
  • Now that your camera is focused on the paper, with the settings adjusted correctly, take a series of photos at different shutter speeds, changing by a factor of 2. (I used: 30, 15, 8, 4, 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, and 1/1,000 sec shutter speeds.)
  • Repeat step 4. This will give you two sets of calibration photos. You will compare these later in this procedure.
  • Download all of the calibration photos onto your computer.
  • Make two data tables in your lab notebook to keep track of the pixel value for each calibration photo. One data table will be for the first set of calibration photos, the other for the second.
  • Measure the average pixel intensity of each photo using ImageJ.
  • Start ImageJ.
  • Open the first photo using “File/Open”... command.
  • Click on “Analyze” and select “Histogram”.
  • A histogram of the pixel values in the photo will open in its own window. You will use the histogram to measure the average pixel gray value in each photo.
  • Record the Mean, StDev, Min, Max, and Mode in your data tables. StDev is short for “standard deviation”. Min and Max are short for minimum and maximum, respectively. Mean is another name for the average. The mean of this histogram is the average pixel value.
  • Click on “File” and select “Open Next” to open the next file.
  • Make a calibration curve by graphing the average pixel value (the mean of the histogram) on the x-axis and exposure time (in seconds) on the y-axis. Your graph will have two data series, one for each set of calibration photos.
  • This is a “semi-log” plot.
  • Look at your graph and check the calibration curves from each set. The two curves should cross or only be a little bit apart. If there is a large amount of space between the two calibration curves or if one of the curves has a drastically different shape from the other, you will need to repeat steps the whole process, making sure that the lighting conditions are the same for both sets.

Paragraph on Light Pollution

Students are often asked to write a paragraph on Light Pollution in their schools. And if you’re also looking for the same, we have created 100-word, 200-word, and 250-word paragraphs on the topic.

Let’s take a look…

Paragraph on Light Pollution in 100 Words

Light pollution is when there are too many bright lights in the night sky, making it hard to see the stars. It’s like when lots of people turn on their flashlights and point them up, and you cannot see the moon anymore. This happens because cities have lots of lights from buildings, street lamps, and cars. These lights make the sky glow and can confuse animals that need the dark, like owls and fireflies. We can help by turning off lights we don’t need and using special covers that stop light from spreading everywhere. This way, we can all enjoy the beautiful, starry night sky.

Paragraph on Light Pollution in 200 Words

Light pollution is like a blanket of unwanted light that covers the night sky. Imagine you’re trying to sleep, but someone keeps turning on the lights; that’s how the Earth feels because of too much light at night. Big cities have lots of bright lights from buildings, streetlights, and cars that make it hard to see the stars. This doesn’t just make it tough for us to spot constellations or make a wish on a shooting star; it also confuses animals that need darkness to find their way or get some rest. Birds that travel at night can get mixed up, and baby sea turtles might crawl towards the city glow instead of the ocean. Even for us, too much light can make it harder to sleep well. Scientists and smart people who care about our planet are trying to fix this problem by making lights that point down to the ground, where we need them, instead of up into the sky. They also suggest using lights only when and where we really need them. By doing these little things, we can bring back the dark night skies, full of twinkling stars, for everyone to enjoy.

Paragraph on Light Pollution in 250 Words

Light pollution is when there is too much artificial light at night. Imagine when you turn on a flashlight in a dark room; it’s easy to see because the light is bright and the room is dark. But what if every light in your house was on at the same time? It would be too bright, and that’s what happens outside at night in many places. This extra light can cause problems for both people and animals. For us, it can make it harder to see the stars in the sky. Stars are like tiny dots of light far away in space, and when the sky is too bright from streetlights and signs, these dots get lost in the glow. Animals can also get confused by all this light. Birds that fly at night might go the wrong way, and baby sea turtles can head towards roads instead of the ocean because they think the road lights are the moon shining on the water.

Scientists are worried about light pollution because it’s not just about not seeing the stars; it can also affect our health. Too much light at night can mess with our sleep, and good sleep is really important for staying healthy. So, what can we do?
