Light Pollution and Our Ecosytem

Until recently, light pollution has been a little known environmental problem. Glare, light trespass, and energy waste are primary ingredients of poorly designed outdoor lighting, but light pollution also causes the loss of our beautiful, star-filled, night skies. It also has potentially serious effects on many aspects of the ecosystem, including human health.

With good quality nighttime lighting, we can improve visibility, safety, and security, minimize energy waste, and have a more comfortable nighttime environment. In addition, all living things have evolved with a day-to-night cycle of brightness and darkness (circadian rhythm). This rhythm is part of our nature, and we need it. Ongoing research indicates there may be serious impacts on human health from overly bright lights and that it severely impacts many forms of nocturnal wildlife.
