What Causes ‘Light Pollution’ and How Does It Affect Us?

Light pollution is like when too many lights are shining in the sky, making it hard to see the stars. It happens because cities have lots of bright lights from buildings and streets. These lights go up into the air and make the night look brighter than it should be. This can confuse animals and even affect how humans sleep.
