Ozone
In the upper layers of the atmosphere, the ozone acts like a protector shield, absorving the UV rays that come from the sun.
However, the ozone is easily destroyed by gases as CFC’s, halogenated compounds, carbon tetrachloride, methyl bromide, HCFC’s and HBFC’s, that are emitted by activities related to industry.
