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...

Mar 13, 2020 · A recent study, Light pollution is a driver of insect declines, says habitat loss, pesticide use, invasive species and climate change have all played a role in insect declines globally, but that artificial light at night is another important—but often overlooked—cause.
Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. In practical terms, light pollution is the presence of unwanted, inappropriate, or excessive artificial lighting.
