Parks awash in light pollution


  • Randy Showstack


The first-ever nationwide survey of light pollution impacts on the U.S. National Park System has found that light pollution is a pervasive threat to national parks, and interferes with visitors' ability to observe stars and the night sky. The survey, which queried National Park Service (NPS) staff, found that dark night skies are a vital park resource, and that light pollution is considered a resource problem in many parks.

The survey credited the National Park Service with already taking some steps to reduce light pollution within parks, but added that the agency can do more to deal with the problem.
