Is there a hole in the ozone layer?
The ozone layer consists of gas, a form of oxygen, which floats about 15 miles above the surface of the Earth, protecting it from ultraviolet radiation.
But British scientists announced 30 years ago that it had begun to break up around the South Pole.
This could mean too much UV is let through putting humans and other animals at risk from skin cancer.

What is causing depletion?
Chlorofluorocarbons, which were commonly used in aerosol cans in the 1980s, were thought to be the culprit.
The gases were thought to float up into the atmosphere and damage the ozone layer.
They have now been banned across the world.
