This interactive activity adapted from the National Park Service describes how humans impact the environment by creating light pollution such as light trespass, glare, and sky glow. Learn how unnecessary light wastes energy, obscures the view of the night sky, and affects wildlife. In addition, explore possible solutions to save energy and minimize light pollution.
This media asset was adapted from "The Disappearing Dark Sky" on the National Park Service’s Webrangers Web site.
