Montreal Protocol

Ozone Layer: The layer in Earth's atmosphere that contains a high concentration of ozone molecules, which help protect us from harmful ultraviolet (UV) radiation.

Chlorofluorocarbons (CFCs): Synthetic chemicals used in various industries, such as refrigeration and aerosol propellants, which were found to be major contributors to ozone depletion.

Ozone Depletion: The gradual thinning or reduction of the ozone layer due to human-made chemicals releasing chlorine and bromine atoms into the atmosphere, leading to increased UV radiation reaching Earth's surface.
