How to bring back the stars in the sky and take away the glare from our eyes.

What Is Light Pollution?

"Light pollution is the effects of artificial lighting that harm the environment or interfere with people's view of the night sky."¹


Here is an example of a night sky without major light pollution. Isn't this something worth working towards?

Light pollution isn't that big of a deal, is it?



  • The night sky—when unimpeded with light pollution—is a scientific laboratory in its own right. Filling it with unnecessary artificial light takes that laboratory away from both professional and amateur astronomers.


  • Light pollution also takes it away from children who might otherwise be inspired to become scientists.




  • Can the driver coming towards you in the opposite lane see you when you're on the road? Wasted light from streetlamps, businesses, and the like can cause glare in a driver's eyes.


Not convinced? Here are even more reasons why unnecessary artificial light is harmful (under The Negative Effects of Light Pollution).
