Ozone is also destroyed naturally in the stratosphere, being dissociated by ultraviolet radiation: This is the reaction that is responsible for O3's absorbtion of uv radiation that would otherwise reach earth.
The depletion of ozone in the ozone layer results in increased amounts of this damaging radiation reaching Earth's surface and an increased occurrence of these problems in humans and other living beings.he stratospheric ozone layer has become substantially depleted throughout much of the globe since the 1980s because of enhanced human production and use of ozone-depleting chemicals, such as chlorofluorocarbons, halons, and others, during the 20th century.
