Ozone absorbs UV-B. UV-B would otherwise damage the DNA of all DNA-based life on / near Earth's surface.

ozone is the chemical in our atmoshere that traps heat from the sun. It acts as a greenhouse, sunlight can come in but it can't go out. Ozone protects Earth by keeping it warm. Ozone is a protectant in the upper atmospere but if found in the lower atmoshere where we live, it is poisonous. Global Warming is caused by having to much ozone in the atmoshere. So in some ways ozone protects Earth by keeping it warm, but it could be a danger to Earth by keeping it too warm.

The Ozone layer protects us from the harmful ultraviolet radiations of the sun which can cause serious damage to the human life causing eye cataract, skin cancer and depressed immune system.
Basically UV-rays. UV-rays convert Oxygen (O2) to Ozone (O3). And Ozone blocks UV-rays. Ozone will eventually fall back to Oxygen. So the Ozone layer is pretty much selfsustaining.

ozone is poisonous and we are lucky that it is not stable nearer to the earth's surface. but it performs an essential function where it is found. it absorbs harmful radiatios from the sun. this prevents those harmful radiations from reaching the surface of the earth where they may damage many forms of life!
