Lumekoristuse

Lumekoristuse, also known as light pollution, refers to the excessive or obtrusive artificial light in the night environment. This phenomenon is primarily caused by human activities, such as the use of poorly designed outdoor lighting, excessive use of light, and the lack of shielding in lighting fixtures. Light pollution has significant environmental, ecological, and health impacts.

Environmentally, light pollution can disrupt the natural day-night cycle of plants and animals, affecting their reproductive cycles, migration patterns, and overall behavior. It can also lead to increased energy consumption and carbon emissions due to the inefficient use of light.

Ecologically, light pollution can alter the behavior of nocturnal animals, leading to increased predation and reduced reproductive success. It can also affect the visibility of stars and other celestial bodies, making it difficult for astronomers to conduct research and observe the night sky.

Health impacts of light pollution include disrupted sleep patterns, increased risk of certain cancers, and potential effects on mental health. The artificial light at night can interfere with the production of melatonin, a hormone that regulates sleep-wake cycles.

Mitigation strategies for light pollution include the use of energy-efficient lighting, proper shielding of light fixtures, and the implementation of lighting ordinances that regulate the use of outdoor lighting. Public awareness and education are also crucial in addressing the issue of light pollution.
