Ozone depletion is the thinning of the ozone layer in the stratosphere, caused by the release of harmful chemicals such as chlorofluorocarbons (CFCs) and halons into the atmosphere. These chemicals are broken down by ultraviolet light, releasing chlorine and bromine atoms that then react with ozone molecules, destroying them. This process creates a hole in the ozone layer, which allows more harmful ultraviolet radiation from the sun to reach the earth's surface. Additionally, other chemicals, such as carbon tetrachloride and methyl chloroform, also contribute to ozone depletion. It's important to reduce the emissions of these chemicals to protect the ozone layer and prevent further depletion.

Ultraviolet (UV) radiation is a form of electromagnetic radiation that is harmful to many living organisms, including humans, animals, plants, ________ ___________ _______ ___________ _____________ ____ _____.
