Light pollution is bad because it dispruts the natural process of the environment. An example of light pollution causing problems is for sea turtles. Sea turtles come to shore to lay eggs. When it is time for their eggs to hatch the baby turtles are programmed to go in the direction of the light from the moon which would lead them into the ocean. If the houses near the hatchlings have lights on the baby turtles will go towards the houses and die because they do not make it to the ocean.
