After some research I found out a very surprising fact about greenhouse gases.

Most of us think greenhouse gases are just damaging the Earth but in actually fact without greenhouse gases the Earth will be cold and dead , no life form can ever survive. 

Surprisingly , water vapor is a greenhouse gas as well. So in a way trees are contributing to global warming but taking in CO2 will overall help the Earth.

Greenhouse gases are useful in some ways such as help maintain the Earth's average temperature.

Human activities have made a big rise in green house gases in the 20th century. That will explain the rise in the Earth's average temperature because greenhouse gases emit and absorb the heat from the Sun. 

Interesting Fact : When you fart you are contributing to global warming as methane is a greenhouse gas.

Slowing down global warming

Global Warming

What we can do about it?

The goal is to bring global warming under control by curtailing the release of carbon dioxide and other heat-trapping "green house gases into the atmosphere.

Reduce electricity usage in our homes.

Switch the normal lightning in our households to energy conserving lightning. The largest source of GREENHOUSE gases are the electric generators.

Drive less

You will be saving energy if you take public transport or walk and cycling to your destination.

Use your air-con less

Air-cons contribute a lot to the GREENHOUSE gases. In the US , air-cons only produce half a billion tons of carbon dioxide.

All this simple things can help the prevention of global warming. So start helping in every way you can
