It is a lot of gases. It is not just one gas.
The gases that come from humans that deplete ozone are many. CFC's are one of the most dangerous of them.
The gases that destroy the ozone layer which protects the earth are various. CFC is one.
There is not just one CFC but a whole family of them and the ratios vary from one member of the family to another.
Not one but various gases are responsible for the destruction of ozone. Carbon dioxide, CFC's, monoxide etc are some. They might not be responsible directly but indirectly too.CFCs. Chlorofluorocarbons.
The man-made gases of CFCs (chlorofluorocarbons). Chlorines and bromines from these gases stay in the atmosphere for years, destroying ozone molecules. This allows the sun's dangerous ultra violet (UV) radiation to reach earth, causing human cancers and damage to crops.
The main one is Carbon Dioxide (or CO2). Also, methane and nitrogen are all trapped in the Earth's atmosphere, and CFC's also.
There are lots of rare gases in the world. One such is helium and other rare gases are neon and krypton.
CFC's are used in refrigerators. One of a CFC is R-12.
CFC's are liberated from AC's. They are one of the main source. CFC's damage the ozone significantly.
An Air Conditioner releases CFC's. A CFC can destroy large number of ozone molecules.
CFC's are destroying our ozone layer. These CFC's are one of the most harmful chemicals of the environment.
