Stratosphere contains ozone layer. It protects us from harmful UV rays of the sun.
mesosphere
The ozone layer is at base of stratosphere. It is a pool of ozone molecules.
Lightning is a massive flow of electrons, that superheats gas to a conductive plasma state, and radiates broad spectrum energetic radiation... including ionizing radiation. Either the oxygen atoms in the plasma, or the ionizing radiation breaks apart oxygen molecules to make oxygen atoms, then some of these now-loose oxygen atoms combine with oxygen molecules to make ozone.
The ozone layer protects your eyes from developing cataracts (as fast). So Sight. The ozone layer protects your skin from developing tumors (as fast). So Touch. The ozone layer protects the rest of the surface world, including birds, and crops, and without it you would have nothing to eat except dirt and rock, and no animals to hear, so Taste, Smell (since it is an important part of Taste), and Hearing.
It does impact the ozone depletion. They act as a base for the depletion of ozone.
There is a ozone hole in Antarctica. It is because PSC's act as a base for reactions.

Polar Stratospheric clouds are formed at poles. They act as a base for ozone depletion.
Due to ozone depletion the harmful UV radiations enter the earth and cause a number of problems. Some of them are: 1) UV radiations cause skin cancer,eye cataract and suppression of immune system. 2) Photoplankons, the base of most of the food chains are destroyed by these radiations. 3) Ozone depletion leads to Global Warming which increases the global temperature of the surface of earth.
The base layer is polycarbonate plastic. Then an aluminium layer is sandwiched between this base layer and a protective (clear) acrylic coating.
One can purchase a thermal base layer from icebreaker website. Eskeez has all types of base layers and for all occasions to keep one warm at the same time.
Polar stratospheric clouds or PSC's are formed at cold regions. These form the base for the various ozone depleting reactions at the poles.
