Ozone Layer and Climate Change

The video discusses the ozone layer crisis of the 1980s, highlighting the discovery of the ozone hole over Antarctica and its potential catastrophic impacts. It details the scientific investigation led by Dr. Susan Solomon, which identified CFCs as the main cause. The global response, including the Montreal Protocol, successfully curbed CFC emissions, leading to the healing of the ozone layer. However, the video emphasizes ongoing environmental challenges, particularly climate change, and the need for continued global action.
