One possible version：
Our Environment in Ten Years: for Better or Worse?
Many students are optimistic about environment in ten years. In fact，they think that the world will be a better place than it is now. More and more people are becoming volunteers to protect environment. The government will take more measures to improve the environment.
However, other students are worried about the future.A large number of trees will be cut down. More and more private cars will be on the road. They say the world will become more crowded.
But in my opinion, I think we should plant more trees and pick up litter around us. We should work together to protect our homes.
