Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, [16] and, like any other form of pollution, disrupts ecosystems and has adverse health effects. [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 ...
Light pollution in Hong Kong. Hong Kong has been named the world's worst city for light pollution. Commercial and residential areas Mong Kok, Tsim Sha Tsui and Causeway Bay are found to be the most severe areas of light pollution. Due to the spotlights and LED billboards, Hong Kong’s sky is many times brighter than other cities.
Data showed that Earth's artificially lit outdoor surface at night grew by about 2 percent annually in brightness and area from 2012 to 2016.
Bortle scale. The Bortle dark-sky scale (usually referred to as simply the Bortle scale) is a nine-level numeric scale that measures the night sky 's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution.
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. The coordinating researchers compile this ...
Polarized light pollution [1] is a subset of the various forms of light pollution referring specifically to polarized light. In nature, water and water vapor polarize the sunlight (which itself is slightly polarized). By receiving the direction of polarized photons, some species can correct their course during migration.
