What is the term used to refer to the thinning of the ozone layer?

The term used to refer to the thinning of the ozone layer is "ozone depletion." This phenomenon occurs primarily due to the release of certain chemicals called chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the stratosphere. The ozone layer is essential for life on Earth because it absorbs the majority of the Sun's harmful ultraviolet (UV) radiation. When the ozone layer becomes thinner, it allows more UV radiation to reach the Earth's surface, which can lead to increased rates of skin cancer, cataracts, and other environmental issues. Understanding ozone depletion is critical for the protection of both human health and the environment.
