One possible version：

Life in the future：for better or worse?

Many students are optimistic(乐观的)about the next fifty years．In fact，they think that the world will be a better place than it is now and our lives will be greatly improved.As a result，people will have a higher standard of living and live longer．

However，other students are worried about the future．They say the world will become more crowded．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．
