Text, Myth vs. Reality 
Myth. Abundant nighttime lighting has no negative effects on human health and nature. 
Reality. Bright city lights can disrupt the natural rhythms and processes of animals, insects, plants, and even people. Too much light at night can cause animal deaths and lead to illnesses in humans.
