The green house gases can be reduced up to a limit by eliminating the fossil fuels and chlorofluorocarbons. Fossil fuels are the major source of greenhouse gases.
<h3>What are green house gases?</h3>
Greenhouse gases are those which are capable of intense absorption of the temperature radiated from the earth's surface and make the earth atmosphere warm up.
Greenhouse gases are the main cause of global warming. Carbon dioxide, methane oxides of nitrogen and sulphur are the green house gases.
Fossil fuels are rich in hydrocarbons and they release these gases when burned. Mainly methane and other hydrocarbon gases intensely absorbs the temperature which is radiating away from the earth and thus the heat is trapped inside.
Therefore, by eliminating fossil fuels, greenhouse effect can be prevented.
