Whatever Happened to the Hole in the Ozone Layer?

The damage caused by chlorofluorocarbons (CFCs) came to light in the 1980s when scientists discovered a huge hole in the ozone layer.
Since the ban on CFCs came into effect, the ozone layer has been recovering, but only very slowly. CFCs released from aerosol cans, refrigerators and air conditioning systems continue to damage layers of the stratosphere decades after their release.
