Why is Ozone so critical?

16 Sep 2015

It is found that ozone is very rare, only three out of 10 million molecules in the air is ozone. If we gather all scattered ozone together, it will be only 3 millimeters thick covering the earth's surface. Besides of ozone, the atmosphere contains of a variety of radiation i.e. UVA and UVB, and gases as well. Some types of gases such as chlorine oxide and bromine oxide can react with the ozone, and catalyze the ozone breakup. From a study, a chlorine molecule can destroy up to 100,000 ozone molecules, this reaction adversely affects the ozone life cycle.

If the stratospheric ozone can not resist this destruction process, what else can help our blue planet to absorb the UVB radiation?
