Every year , the South has the floods . It is an act of God .   Do you really think so ?   Yeah , you have some other ideas ?   Think , in some way it is an act of God , but in another way , it just is caused by us .   For example ?   We didn't pay attention to the environment , cut down trees and polluted the air .   Oh , I see . Fortunately government has taken some action to prevent such things .
