Ozone watch

The ozone layer protects the Earth from about 98% of the Sun’s harmful ultraviolet light.

Ozone Hole

Unfortunately, human use of chlorofluorocarbons (CFCs) has damaged the ozone layer and now, from September to December every year a great big “hole” (actually an area of low concentration) appears over the Antarctic.

You can track the damage to the ozone layer via NASA’s Ozone Hole Watch.
