Saving Earth's Ozone: A Look at the Disappearing Antarctic Ozone Layer

Explore the urgent issue of the depleting Antarctic ozone layer in 2006 caused by chlorofluoromethanes. Understand the role of polar stratospheric ice clouds and the catalyst effect of stratospheric clouds. Learn why the ozone layer was vanishing faster than expected and how the Montreal Protocol of 1987 led humanity to agree on reducing ozone-destroying CFCs to combat this environmental threat.
