It’s increasingly common in today’s society to use outdoor lighting around our homes and businesses to draw attention to a sign, provide security and allow people to be more active at night. However, according to a recent article at Discovery-News. com, scientists suggest that light pollution is a growing problem for wildlife. Migratory birds are getting confused and flying into the sides of skyscrapers. Nocturnal(夜间活动的)creatures have to hurry when they’re out looking for dinner(while becoming easier to be dinner when they’re out looking for food). And newborn sea turtles are crawling inland rather than heading out to sea.
Travis Longcore, director of the California-based Urban Wild-lands Group said, “We’ve turned many places of the globe into permanent full moon, or more. ”And this “permanent full moon” effect is causing animals that depend on the darkness of night for their survival to lose all sense of direction.
Instead of totally pulling the plug on lights, there are a few ways we can cut down on the amount of nightly light pollution we help create. Some communities and cities have passed Dark Sky laws to preserve and protect the night-time environment through quality outdoor lighting.
Chicago, for example, became the first city in the United States to dim their tall buildings at night during spring and fall bird migrations. The Windy City does this for nearly five months a year, in an effort to help save birds’ lives.
