The document discusses the ozone layer in the Earth's stratosphere that protects the planet from harmful UV radiation. It is formed through a reaction involving oxygen and ultraviolet light. While ozone itself is poisonous at ground level, the ozone layer is beneficial as it prevents excessive UV radiation from reaching the surface and causing issues like skin cancer. However, the ozone layer is under threat due to ozone depleting substances released into the atmosphere such as CFCs, halons, HCFCs, and methyl chloroform which are used in products like refrigerants and aerosol sprays.
