Our Environment in Ten Years：for Better or Worse？

Many students are optimistic about our environment in ten years．　In fact，they think that more and more people will take part in the environmental protection and our government will take more measures to improve our environment．As a result，our world will be more beautiful and we will have better lives．

However，other students are worriedabout the future．They say a number of trees will be cut down and there will be more and more private cars．．Therefore，we will have even more environmental problems and live in a world with less energy available．

But in my opinion，I think we will find ways to solve our problems and everyone will live more happily．　．
