Visual pollution

Light pollution exceeding its limit has the potential to harm not only human health but can also affect our environment. Did you know photo pollution increases air pollution by suppressing a naturally occurring radical that cleans the air at night? Artificial lights from buildings, cars, and streetlights, although 10,000 times dimmer than sunlight, also affect nitrate radical and slow down the cleansing process by 7%. Artificial light also increases the chemicals for ozone pollution by 5%.
