The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation.
The gradual depletion of the ozone layer and the related greenhouse effect has now reached crisis proportions as a consequence of industrial growth, massive urban concentrations and vastly increased energy needs. The ozone depletion potential (odp) of a chemical compound is the relative amount of degradation to the ozone layer it can cause, with trichlorofluoromethane (r-11 or cfc-11) being fixed at an odp of 10. The emission of ozone depleting substances has been damaging the ozone layer but through domestic and international action, the ozone layer is healing and should fully recover by about 2065 this website addresses stratospheric ozone issues, including the science of ozone depletion, epa's regulatory approach to protecting the ozone layer, epa.
