The stratospheric ozone layer makes it possible for life to exist by shielding the earth from harmful ultraviolet (UV-B) rays generated from the sun. There is a substantial amount of scientific evidence that suggests man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). Decreased concentration of stratospheric ozone allows increased levels of UV-B rays to reach the earth's surface.
Simple answer: it is believed CFC destroys the ozone layer in the atmosphere which creates problems with the environment we all live in.
CFC is an abbreviation for the class of chemical compounds known as Chloro-Fluoro-Carbons.
CFC's are dangerous. These CFC's result in mass depletion of ozone layer.
Humans produce CFC's. These CFC's react with ozone to deplete it.
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.
lead additive to fuel and CFC gases
they are not harmful to the environment
CFC's are stable. They are compounds of carbon, Chlorine and Fluorine.
CFC's are destroying our ozone layer. These CFC's are one of the most harmful chemicals of the environment.
Yes, it is. It contains CFC's.
Man can keep environment ozone friendly. It is by curbing the use of CFC's.
CFC's are man made compounds. They are bad for ozone as they deplete it.
Simple answer: it is believed CFC destroys the ozone layer in the atmosphere which creates problems with the environment we all live in.
A CFC (Chlorofluorocarbon) comprises carbon, chlorine, and fluorine atoms. These compounds are typically used as refrigerants, propellants, and solvents, but they are harmful to the environment as they contribute to ozone depletion in the atmosphere.
We switched to using smokeless fuels, and spearheaded the campaign for the abolition of CFC's from aerosols.
The number of CFC's are to be contained. If we want to save Antarctic.
Hairspray contain CFC's. They react with ozone to deplete them.
