According to a 2016 report by the New World Atlas of Artificial Night Sky Brightness on global pollution, more than 80% of the world is affected by Light pollution
Light pollution affects human health, wildlife, and the ecosystem adversely
Here are some facts about light pollution
Research by American Ornithological Society points out that artificial light deviates birds migrating at night from their path hundreds of miles away
Bright lights on buildings attract birds due to which several birds are killed after collision
The report also states that trees get illuminated by the surrounding light and shed off their buds and leaves earlier
Exposure to artificial light for a long time suppresses the secretion of melatonin, a hormone essential for the regulation of the sleep-wake cycle

The same study found that the blue wavelength in bright light activates special cells in the retina that affects the brain's mood, memory, and learning
The International Agency for Research on Cancer classified night shift work as a probable carcinogen for women exposed to higher levels of light
A study by Bangor University and the University of Plymouth shows that artificial lights disrupt lunar understanding of coastal creatures migrating at night
Using natural light or incandescent bulb that radiate light from heat alone reduces the impact of light pollution
