Ozone Layer & UV Radiation
Explore the stratospheric ozone layer that absorbs harmful ultraviolet (UV) radiation, protecting life on Earth. Understand how chlorofluorocarbons (CFCs) from aerosols and refrigerants catalytically destroy ozone molecules, creating the ozone hole over Antarctica. Learn about the Montreal Protocol (1987), the most successful international environmental agreement, which phased out ozone-depleting substances and enabled ozone layer recovery.
