Efforts are being made for substituting the chemicals like CFCs. Why?
CFCs are chlorofluorocarbons are the synthetic chemicals which are made by humans artificially, that means they are not the natural products. Excessive use of these CFCs in refrigerators, ACs, fire-extinguishers, etc. causes the depletion of ozone layer. Because then UV radiations will reach the earth’s surface destructing the survival of plants and organisms.
