The Antarctic Ozone Hole is an annual springtime event above Earth's frozen, southernmost continent. Manmade CFCs, naturally occurring Polar Stratospheric Clouds, and the return of sunlight set off incredible destruction of the protective Ozone Layer. This video presents these complicated processes with simple to understand animations.
