Cfcs Cause Deterioration of the Ozone Layer


The deterioration of the ozone layer , caused by Cfcs, endangers the
lives of humans'. Cfcs have a diminishing effect on the ozone layer.
Furthermore, the deterioration of the ozone cause an increase of Ultraviolet
(UV) radiation which can have a negative effect on human skin and eyes. As a

ozone.
This atmosphere extends many miles out from the earth's surface.
However, this layer is not a uniform layer, from top to bottom. As one moves

The first region is the troposphere which extends about......
