Fighting Light Pollution
Artificial light includes light from signs and streetlamps. These help people see once the sun goes down. But too much artificial light becomes light pollution. This makes it difficult to see a starry sky. And it affects animal behavior.
From April 21 to 28, people will celebrate International Dark Sky Week. It’s an annual event intended to inspire people to reduce light pollution. Started in 2003 by a teenager, the event is now organized by DarkSky International. The group’s website recommends that people use outdoor lighting “only when needed.” It also suggests that people “help spread the word about light pollution.” One way to do this is by gathering outdoors with friends, family, and neighbors to enjoy the glittering night sky.
