Reduction and prohibition of CFC and greenhouse gases is one of the strategies to deal with Global warming. Due to increase of emission of greenhouse gases like carbon dioxide, nitrous oxide, ethane, methane, sulphur dioxide, CFC11(chlorofluoro carbon), CFC12, CFC113, and CFC114, the amount of heat that could be radiated back into space at night is reduced considerably and as a result the temperature of earth is increased.
