Learn How to Proect the Night from Light Pollution

Light pollution is increasing worldwide at twice the rate of global population growth. Eight out of ten people live under a light-polluted night sky, at least three billion dollars is wasted on outdoor lighting each year in the U.S., and virtually every species studied has been harmed by light pollution. But the solutions to reversing these trends are simple. Learn more about IDA’s work to protect the night from light pollution.
