Ozone depletion refers to the reduction in the concentration of ozone (O3) in the Earth’s stratosphere, a layer of the atmosphere that protects us from harmful ultraviolet (UV) radiation from the sun. Depletion of the ozone layer has been caused by the release of man-made chemicals, primarily chlorofluorocarbons (CFCs), into the atmosphere.
Protecting the ozone layer is crucial for several reasons. It shields us from harmful UV radiation, which can cause skin cancer, cataracts, and immune system suppression. It also protects plants and marine life, and plays a role in regulating the Earth’s climate.
