　　A:the pictures exhibit a man is sawing down another tree in the area.

　　Forests in china are getting smaller and smaller.there are much flood every years in china,many wild animal have disappeared ,dessert is getting larger and larger,sandstroms are emerging in most of cities in china.

　　there are at least one reason to explain the issue.

　　people cut trees for money,they think these trees will be grow naturally and they don't need much time to care for them.

　　We should protect environment,if we don't protect environment ,it is getting worse and worse.we destory our earth and actually destory oursleves.those people cutting trees should be punished severely.

　　B:I agree with you.Once destroy has been done,it is impossible to recover.in the past 20 to 30 years,there are nartural disaster occuring each year.even if we stop destroying environment,there are no way to restore our planet.if we continue destroying our environment,we can imagined that people will completely destroy earth.
