If ozone in the stratosphere. Reached the stratosphere 30 miles above the ground, and on top of the page contains ozone. The sun's rays by ozone in the stratosphere, and not from the earth.

Ozone is a bluish, consisting of three oxygen atoms. Form of the oxygen we breathe, man consists of two oxygen atoms, O2. If on the surface of the planet, ozone is considered one of the most dangerous pollutants, and is a feedstock for the production of greenhouse gases.

The largest part of the stratosphere contains about 90% of all ozone.

In recent years, the ozone layer is the subject of numerous discussions. And rightly so, the ozone layer, the protection of its fauna and flora on the planet.

The fact that the ozone layer, the depletion was in the mid-1980. The main reason is the release of CFCs, HCFCs.
