Light pollution is when too much artificial light makes the night sky bright, like a big blanket covering the stars. It happens because people use lights at night, such as streetlights and signs, which can hurt our ability to see the stars and affect animals that rely on darkness.
Examples
- A streetlight shining bright all night hides the stars above.
- Birds get confused by too many lights on buildings at night.
