Ozone depletion refers to the thinning of the ozone layer, which is crucial for protecting life on Earth from harmful ultraviolet (UV) radiation. This phenomenon is primarily caused by human-made chemicals, particularly chlorofluorocarbons (CFCs), which break down ozone molecules in the stratosphere. The consequences of ozone depletion include increased rates of skin cancer, cataracts, and other health issues, as well as negative impacts on ecosystems. Global efforts, such as the Montreal Protocol, have been implemented to phase out the use of ozone-depleting substances, leading to signs of recovery in the ozone layer.
