Stratospheric Ozone Destruction is a Health Risk

Ozone in the earth's stratosphere protects the earth from the penetration of harmful ultraviolet (primarily UV-B) solar radiation by absorbing most of this harmful UV-B, allowing only a small amount to reach the earth's surface. Without the filtering action of the ozone layer, more of the Sun's UV-B radiation would penetrate the atmosphere and reach the earth's surface. Increased UV-B radiation can lead to increased incidence of certain skin cancers and cataracts, as well as other human health and environmental consequences.
