Montreal Protocol on Substances that Deplete the Ozone Layer

The Montreal Protocol is an international treaty established in 1987 aimed at protecting the Earth's ozone layer, which shields us from harmful ultraviolet (UV) radiation. The agreement focuses on phasing out substances, such as chlorofluorocarbons (CFCs), that deplete the ozone. Countries around the world committed to reducing and eventually eliminating these harmful chemicals, leading to significant recovery of the ozone layer. The Protocol has been successful and is considered one of the most effective environmental agreements, demonstrating global cooperation in addressing a pressing environmental issue.
