Why are scientists worried about the Ozone Layer?

• Because it is preventing some of our satellites from reaching the thermosphere.

• Because it's not as pretty as it once was.

• Because people are putting things (like burning fossil fuels) into the atmosphere that are causing holes in the ozone layer which will allow more of the sun's radiation to reach the surface of Earth, making Earth warmer than it's ever been.

• Because it's growing larger and larger and soon it won't allow any of the sun's heat to reach the Earth and it will then become too cold on Earth to support life.
