39、来拯救环境。我不同意她的观点，因为那样的话，许多人将会失去工作。我认为人类比鱼类和树木更加重要。However,I do agree that we should produce more things from materials that have been recycled,and less from raw materials,the supply of which is growing smaller and smaller.What we need are better laws to preservethe environment and still allow our coun
