The nonprofit group known as the International Dark-Sky Association (IDA) has been working since 1988 “to preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.” Members of the organization have worked as advocates to protect the night sky and to educate the public, while also playing policymaker to help conserve the night sky, promote environmentally responsible outdoor lighting and empower the public to help bring back the night sky. By May 2019, IDS had declared 115 communities, parks, reserves and sanctuaries around the world with their International Dark Sky designation.
Not only does light pollution limit human enjoyment of the night sky, but research has shown it impacts the activity of phytoplankton and the egg-laying cycle of sea turtles. Shown here, the silhouette of an ancient pueblo at Wupatki National Monument near Flagstaff, Arizona, which highlights the splendor of a natural, dark sky.
