Several groups have formed to fight light pollution. States and cities have passed laws to cut down on nighttime light. Some of these laws require outside lights to have shields above them. The shields direct the light toward the ground. They keep the light from shining up into the sky.
Many people are also concerned about the electricity that is wasted in lighting the sky.
Something to Do 1. With an adult family member, go outside on a dark night, as far from lights as you can go. Look at the stars. Then turn on a flashlight or stand under a streetlight.
