Our Earth...

I find a problem about the global warming. It says the temperature has increase the ice was melt and some animal species is become extinct. I am interested about the problem. I want to present to my friends and this is my opinion.

In our Earth have many living thing lives and stays. Such as, plants, human, insect and animal. All living thing use many materials in our world. It can make our Earth be decay. The important factor that makes the Earth decay is human. Human uses benefit from the Earth to let them be convenient. Previous times the human didn’t care about Earth they make the Earth going bad. They used too much material in the Earth to make them had a good life. They make many problems some problem we have to use long time to repair. Global warming is the example problem that they made by many cause. For example Co2, CFC[Chlorofluorocarbon that used in air conditional],Methane gas etc.. .

Global warming

Global warming makes a climate change. The temperature increases very quickly in this 40 years .The main cause is human. Previous times the human never care about effect that will happen in the future. They used a lot of material and poison gas. The main cause is greenhouse gas that absorbs heat in the Earth. Example gas is Co2 that produce by the machine car.
