of the ozone layer is serious problem all over the world. More ozone-depleting
gases have been identified in the atmosphere by scientists. Researchers at the University
of East Anglia have found two new types of man-made gases. The gases which have

one, and are unlikely to pose a threat to the ozone layer. We must controls on
CFCs to preserve ozone in the stratosphere that protects life on Earth by
absorbing harmful ultraviolet radiation from the sun came.
