La capa de ozono

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 and attributes its cause to chlorofluorocarbons (CFCs) used in aerosols and refrigerators. Despite bans on CFCs in the 1990s, their long-lasting effects continue to damage the ozone layer. However, recovery efforts are underway, and scientists predict the ozone hole will close in 50 years. The video emphasizes the need for continued protection of the ozone layer to safeguard life on Earth.
