What is Light Pollution?

When you look outside, can you see stars? Probably not. How about the galaxy? No? Well that is because of light pollution. Light pollution is excessive, misdirected, or obtrusive artificial (usually outdoor) light.Too much light pollution has consequences: light pollution washes out starlight in the night sky, interferes with astronomical research, disrupts ecosystems, has adverse health effects and wastes energy. ... affects our sky, humans and animals. Light pollution causes use to not be able to see the stars and sometimes will cause seasons to come earlier. Light pollution can even cause cancer.

The Problem!

The problem that occurs with light pollution is that light pollution effects a lot of living things and even our sky here are some problems light pollution can cause. Light pollution It can confuse the migratory patterns of animals, alter competitive interactions of animals, change predator-prey relations, and cause physiological harm.Nighttime death tolls are just part of the picture. The American Bird Conservancy estimates that 300 million to 1 billion birds each year perish from building collisions, the leading human-related cause of bird deaths.Light pollution shown to affect plant growth, food webs. Artificial night time light from sources such as street lamps affects the growth and flowering of plants and even the number of insects that depend on those plants for food. This picture shows light pollution spread all over the world

The Solution We Can Use

The solution we can use to solve this world wide problem is we can all turn off our lights more often and remove a lot of the city street lights to decrease some of the light pollution. We can also replace lights with CFL and LED lights. This will help a lot because it saves energy Switching to LED lighting allows for reduced illuminance without compromising visibility. And also avoid using blue lights at night. Blue-rich white light sources are also known to increase glare and compromise human vision, especially in the aging eye.

If It Continues

If light pollution continues then some birds will become extinct or endangered. There are 400 billion birds in the world and 300 million to 1 billion birds die every year so causing major food lose for animals who eat birds. This will also affect us humans because it causes glare in our vision and cancer which will damage our health a lot. Some lights even harm other living things such as bees hummingbirds humans and plants.

How Will I Help

To help stop light pollution I will turn off unnecessary lights. I will also tell my family members and peers about it and ways they can help stop this really big problem so it doesn't worsen into a even bigger problem. Another thing I will do is talk about how we can use LED lights to help the cause.
