2. Light pollutionLight pollution, also known as photopollution or luminous pollution, is excessive or obtrusive artificial light. The International Dark-Sky Association (IDA) defines light pollution as: Any adverse effect of artificial light including sky glow, glare, light trespass, light clutter, decreased visibility at night, and energy waste. This approach confuses the cause and the result, however. Pollution is the adding-of/added light itself, in analogy to added sound, carbon dioxide, etc.
