[17] [18] [19] Light pollution is a side-effect of industrial civilization. Its sources include building exterior and interior ...
Ecological light pollution [1] is the effect of artificial light on individual organisms and on the structure of ecosystems as a whole.. The effect that artificial light has upon organisms is highly variable, [2] and ranges from beneficial (e.g. increased ability for predator species to observe prey) to immediately fatal (e.g. moths that are attracted to incandescent lanterns and are killed by ...

The dark-sky movement is a campaign to reduce light pollution.The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of electric lighting on the environment, improving the well-being, [1] health [2] and safety [3] of people and wildlife, [4] and cutting down on energy usage.
Globe at Night is an international scientific research program that crowdsources measurements of light pollution in the night sky. At set time periods within each year, the project asks people to count the number of stars that they can see from their location and report it to the project's website.
Light pollution is the presence of unwanted, inappropriate, or excessive artificial lighting in the visible spectrum. It may also refer to: Radio spectrum pollution; Polarized light pollution, the form of light pollution specific to polarized light
Light pollution is a growing problem in reaction to excess light being given off by numerous signs, houses, and buildings. Polluting light is often wasted light involving unnecessary energy costs and carbon dioxide emissions. Light pollution is described as artificial light that is excessive or intrudes where it is not wanted.
Light poverty is the state or condition in which people or communities lack artificial or electric light after sunset. This originates from many social and economic reasons, including inability to afford efficient lighting.
