The ozone hole over the Antarctic region is a seasonal depletion of the stratospheric ozone layer that occurs during the Southern Hemisphere's spring, which is caused by a combination of low temperatures, high altitude, and polar winds. While human-made pollutants such as chlorofluorocarbons (CFCs) have been shown to contribute to ozone depletion, they are not the primary cause of the Antarctic ozone hole.
