Why is this important?

Ozone is an extremely reactive gas composed of three oxygen atoms. It is the primary ingredient of smog air pollution and very harmful to breathe. Ozone essentially attacks lung tissue by reacting chemically with it. It also damages crops, trees and other matter -- even breaking down rubber compounds.
