The video explains the importance of the ozone layer in protecting Earth from harmful UV rays. It discusses the discovery of the ozone hole over Antarctica, primarily caused by CFCs used in aerosols and fridges. Although CFCs were banned in the 1990s, their effects persist for decades. The ozone layer is slowly recovering, but full repair will take time due to links with global warming. Protecting the ozone layer is crucial for life on Earth.
