Antarctica is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. 

The Antarctic Ozone Hole

You will no doubt have heard of the hole in the ozone layer above the Antarctic. CFCs (chlorofluorocarbons) cause ozone depletion when they are released into the atmosphere. It is thought, however, that the extreme cold of the Antarctic may also be a factor in ozone depletion, as there is a similar hole over the Arctic. The decline of Antarctic ozone could be a sign of a more worrying global ozone breakdown.
