The phenomenon that describes the deficiency of the ozone layer in the atmosphere is known as ozone depletion. Ozone depletion primarily occurs due to the release of man-made chemicals, such as chlorofluorocarbons (CFCs), which break down ozone molecules in the stratosphere. This thinning of the ozone layer has significant consequences, including increased ultraviolet (UV) radiation reaching the Earth's surface, leading to higher rates of skin cancer and affecting ecosystems. Global efforts, such as the Montreal Protocol, aim to protect and restore the ozone layer.
