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 breakdown of ozone in the stratosphere results in reduced absorption of ultraviolet radiation. Consequently, unabsorbed and dangerous ultraviolet radiation is able to reach the Earthâs surface at a higher intensity. Ozone levels have dropped by a worldwide average of about 4% since the late 1970s.
