Nitrous Oxide or N2O: It is created by the degradation of microorganism such as bacteria. The reason of nitrous oxide increases in the present is because the industrial sectors such as Nylon Fiber, Chemical and Plastic industries have used Nitric Acid in their production. The increase of N2O affects directly the increase of heat in the atmosphere around 0.14 watts per square meter. Besides, N2O also reacts with ozone gas leading to destroy the UV radiation protection.
