What are the Effects of Light Pollution?
When we over-light, fail to use timers and sensors, or use the wrong color of light, we can negatively affect many parts of our world.
Destroys critical wildlife habitat
Plants and animals depend on Earth’s daily light and dark cycle to govern life-sustaining behaviors. Research shows that artificial light at night has adverse and even deadly effects on many species.
Decreases safety and security
There is no clear scientific evidence that increased outdoor lighting deters crime. In fact, glare from unshielded streetlights can decrease personal safety, contributing to both crime and accidents.
Wastes energy and money
Most outdoor lighting is wasted. This energy waste increases greenhouse gas emissions contributing to climate change and wastes billions of dollars each year.
Robs us of our night sky heritage
Our ancestors experienced a night sky that inspired science, religion, philosophy, art, and literature. Now, millions of children across the globe will never know the wonder of seeing the Milky Way.
Harms human health
Studies indicate that artificial light at night negatively affects human health by increasing our risks for obesity, sleep disorders, depression, diabetes, breast cancer, and more.
