Hi! Chaobo

I think the scientists have reasons to say so. However, I don't think we can live at this time.The most important thing that we should keep our environment clean and green to avoid the green house effect . It will make us suffer in the disaster such as tidy waves, earthquakes, typhoon,cyclone..etc..You're Chinese,do you live nearTaiwan?There are a lot of storms in your country recently, do you feel afraid about pollution?Your industrial tcchnique is developing faster than never before, so there is a lot of pollution, isn't it?I'm very interested in using your productions.They are very cheap and beautiful: MP3,MP4, USB,Radio, VCD, Comestics and even clothes.......Your country is very large,if you don't keep your  forests, it will give a lot of flood to all around the world.And the futureabout the Mars and the ice age , I will wait for the after-life to affirm it is really right or wrong.Hope to receive your answer as soon as possible.

yeah,i also come from china,and I know that the environment situation doesn't seem to be so sound as before as the economy grows dramatically.I think this is a problem that every country must face on the road of persuiting a mighty power.but the final outcome still depends on that how the contry handle the issue.a capable government will put everything under control,for example,in china, many efficient measure have been taken to deal with them.

of course,the global weather is a worldwide issue,every country has the obligation to the earth a better place to live.
