Light Pollution –The effects on animals and humans

Light Pollution, is one of the lesser-known forms of pollution. Even though it is not well known, it is still a problem and affects us, and our environment in many ways. 

‘Light pollution’ can be described as the inappropriate or excessive use of artificial light at night. In recent years, public concern about the environmental and health effects of light pollution has increased, particularly in North America, Europe and some Asian cities.

"The non-visual impacts of light at all hours can affect our mood, behaviour and our circadian rhythm",  

For Animals, artificial nighttimes light can have devastating effects because it affects their migratory patterns, sleep and wake cycles and even habitat formation, National Geographic reports. Countless insects are killed because they are attracted to artificial lights and then die on contact with the light source. And many birds and even sea turtles die because artificial light causes them to lose their way while migrating.

Even Humans, can be out of whack because artificial night light can interrupt our sleep cycles and effect our circadian rhythm. Among the many processes regulated by the circadian rhythm is the production of melanoma, a hormone that plays a role in sleep. Increased light at night, when it should be dark, slows melanoma production, which can cause anxiety, fatigue, headaches and sleep deprivation,
