Now I'm going to talk about global warming which is a huge problem currently in our world and its affecting our planet. Global warming as we know refers to rising temperatures of air and ocean caused by greenhouse effect. Many of the data's show that the rising temperature average is 0.5ºC during the last century. We must remember that the causes of this increase are mainly because of man, many people aren't really worried with what's happening to our planet and still doing inedaquate behaviours to the pollution. However many are done by Quioto Protocol
in a way which it warns people to change their behaviours but the truth is that the biggest polluter is the USA, they hasn't signed the deal.

The climate is changing and causing catastrophies.
We confront problems more intractable than any previous gerenation, some of them apparently insoluble at the moment.
Environmentalists say we can still save the Earth as long as we try to change our habits and consumer lifestyle.
Our planet is under pressure and we must to save him.
