The Ozone Layer

The video explains the ozone layer's role in protecting Earth from harmful UV-B light, the causes of its depletion, primarily due to CFCs, and the subsequent recovery efforts. It highlights the impact of climate change on the ozone layer's ability to repair itself, noting that while ozone depletion doesn't cause global warming, climate change affects ozone recovery. The video also discusses the historical context of CFC usage and the observed changes in the ozone hole over Antarctica.
