Light pollution is the presence of any unwanted, inappropriate, or excessive artificial lighting. [1] [2] In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind ...
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.
To make that assumption work, astronomers have used the concept of dark energy. For a century, scientists have thought that the universe was expanding in all directions.
Light pollution, the introduction of artificial light into formerly dark ecosystems, has numerous adverse ecological effects. Exposure to artificial light can prove fatal for some organisms (e.g. moths that fly into a burning flame), can interrupt a life cycle phase for others (e.g. glowworms are unable to attract mates), and can reduce the ...
One consequence of artificial light pollution [3] is that even brief periods of relatively bright light during the night may prevent plants or animals (including humans) from measuring the length of the dark period, and therefore from behaving in a normal or required manner. This is a critical aspect of scotobiology, and one of the major areas ...
Humans cannot perceive this pattern, but some arthropods can. Skyglow, and more generally light pollution, has various negative effects: from aesthetic diminishment of the beauty of a star-filled sky, through energy and resources wasted in the production of excessive or uncontrolled lighting, to impacts on birds [22] and other biological ...
Light pollution is the adverse effects of artificial light. [8] Affected parties of light pollution include: [9] Astronomers: By increasing the number of participants, the quality of viewing the sky and stars will be temporarily improved. This is of benefit to astronomers who are faced with light pollution issues such as light trespass and ...
