Light pollution is the human-caused alteration of outdoor light levels from those occurring naturally. It threatens ecological and commemorative integrity, interferes with amateur and research astronomy, degrades the appreciation of mythologies and cultural practices related to the night sky, mars wilderness experience and landscape beauty, carries risks to human health and wastes energy. Counterintuitively, excess outdoor lighting reduces safety and security.
