Light pollution is the alteration of the natural patterns of light and dark in ecosystems, resulting from artificial lighting. In a descriptive sense, light pollution occurs when artificial light is used in a poor or excessive way, especially at night, causing negative effects in the environment and the view of the night sky. Light pollution doesn't just negatively affect human health, but also the plants and animals that live within the wide surrounding regions affected by artificial lighting.
