What is Greenhouse Effect?
Greenhouse Effect
Our earth reflects a lot of energy back into the atmosphere. But presence of heavy carbondioxide in the atmosphere prevents some of this heat escaping just as a glass or plastic sheet stops escaping heat from the so called “Greenhouse” used to protect groing plants.
The main Greenhouse gas is carbondioxide(Co2). The source of this gas is from fossil fuel combustion like coal, petroleum and natural gas. Methane(CH4), Chlorofluorocarbons(CFCs) and Nitrousoxide(N2O) are among the other Green house gases. The sources of such gases range from Bio-mass buring fumes emitted from refrieration and air conditioning plants industrial fumes and enteric fermentation of cattle, insects and different crops.
