WEAKENING OF THE OZONE LAYER

In the average and high altitudes a remarkable reduction of the stratospheric ozone layer has taken place, catalyzed by the residues of hydrogen, nitrogen and free radicals of halogenous. These chemical substances are of natural origin but their concentrations in the atmosphere have increased during the past few years because of the industrial activity. The majors reduction degrees take place in the polar regions. The consequence of the reduction of the stratospheric ozone layer is the increase of proportion of ultraviolet radiation to pave that it arrives at the Earth surface, the ultraviolet radiation will have a direct hit in the health of the people with increase of the incidence of the cancer in the skin and the incidence of ocular injuries, like the cataracts.
