6 days ago · light pollution, unwanted or excessive artificial light. Like noise pollution, light pollution is a form of waste energy that can cause adverse effects and degrade environmental quality.
Light pollution is caused by inefficient or unnecessary use of artificial light. Specific categories of light pollution include light trespass, over-illumination, glare, light clutter, and skyglow. A single offending light source often falls into more than one of these categories.
Light pollution can also sometimes refer to the (mostly human-centred) effects of light, which include glare (disruption of vision due to overly high luminance), light trespass (light shining...

One of the immediate effects light pollution has on our environment is to obscure our view of the true night sky, according to telescope manufacturer Celestron. Without the presence of artificial light, the night sky is awash with celestial bodies, far away galaxiesand constellations. However, if you’re looking up from the belly of a big city, you’...
Other than depriving us of a starry star, there are many more implications to excess use of artificial light, such as throwing the human body's natural cycle out of whack. Circadian rhythms are a group of physiological and neurological changes that occur in the body over a 24-hour-period. Collectively they’re also known as our body clock and is rel...
Along with health issues, light pollution can interfere with the behaviours of wildlife. Nocturnal predators such as batsare among the most affected by light pollution. These flying mammals are well adapted to hunting at night and actively avoid illuminated areas. Unfortunately, their insect prey is attracted to light sources, which leads to barren...

Light pollution takes many forms, like the sky glow visible in metropolitan areas and the cluttering effect common around brightly lit baseball stadiums and highways. Trespass is another, when unwanted light spills into unlit areas. Light pollution can affect animals in many ways.
