"Ozone destruction" refers to the process in which the ozone layer, a protective layer in the Earth's atmosphere, is being damaged or depleted. This usually occurs due to the release of certain chemicals, like chlorofluorocarbons (CFCs), into the atmosphere. Ozone destruction is a significant environmental issue, as it allows harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, leading to various health and environmental problems.
