Global warming means raise of atmosphere temperature due to green house gases. We should stop it. It can create big problems and threat to ozone layer and mankind. It can cause cataract , skin cancer , etc. Fortunately we r getting an early warning. We have to save our death as it is very precious to us. It is rightly said that, " Global Warming is a Global Warning". So take a pledge to save mother Earth.
