Global warming is the process by which the earth absorbs and traps the sunlight with the help of greenhouses gases like carbon dioxide. Global warming is necessary for life on planet Earth.

Life without global warming - 

LIfe on Earth without global warming would be very cold. Plants wouldn't ne able to grow thus affecting the entire food chain.

Green house gases-

Green house gases are the gases which trap the heat. Some green house gases are Carbon dioxide, methane, water vapour and nitrous oxide.The increase of these gases will lead to many unfortunate events.

Overheating of the Earth - 

The incerase in these gases will lead to over heating of the Earth which will make it a dufficult and hard place to live in. The cool oceans and seas will heat up and the marine animals will not be able to live in them. The ice caps will start to melt and join the water bodies which can cause floods. The animals living in the polar regions, like polar bears etc. will die without being able to adapt to a hot and humid climate.Earth will be a too hot place for humans to live in too. There will be many heat waves and diseases will increase alot.

So lets all take steps to help build a cool and happy earth.
