I'm looking for information on the ozone layer and the effects of pollution on it.

The Ozone Layer is a region in the upper atmosphere that absorbs most of the sun's harmful ultraviolet (UV) radiation, protecting life below. It is composed of three main layers: the troposphere, stratosphere and mesosphere. The Troposphere is the lowest layer and extends from the surface to about 10-12 km above sea level. The Stratosphere starts at about 12 km and ends at about 50 km. The Mesosphere begins at about 50 km and goes up to about 80 km. The Ozone Layer absorbs UV radiation which causes damage to living organisms such as plants and animals. Pollution can cause an increase in UV radiation, which has been linked to increased skin cancer rates among humans.
