ABSTRACT
The article focuses on the condition of the Earth's ozone layer. The ozone layer is a three-millimeter thick layer of gas that encircles the Earth. Such layer protects the planet from dangerous ultraviolet (UV) radiation, which promotes human skin cancers and cataracts and weakens the human immune system. Chlorofluorocarbons (CFC), halons and other man-made chemicals destroy the ozone layer. As the layer thins out, it promotes health problems and may even affect the environment. But steps are being taken now to reduce ozone-depleting gases.
