ozone depletion

The ongoing reduction of ozone in the stratosphere. Ozone (O3) is present in 1 ppm in the upper stratosphere, and it absorbs virtually all of the UV radiation from the sun; increased rates of sun-induced malignancies (e.g., melanomas) have been attributed to the destruction of the ozone layer. Ozone depletion is caused by the release of chloride ions from CFCs (chlorofluorocarbons) after release from air conditioners, spray cans, and manufacturing plants that produce electronics and plastics. CFCs degrade in the atmosphere, release chlorine and cause ozone destruction, remain free, or react with ozone to form ClO (chlorine monoxide); O3 is being depleted at a rate of 4–5% per decade.
