翻译一下!
Perhaps there will not be enough room for everybody on earth. So people may live in space stations on the moon. They must be able to grow vegetables there.
Perhaps there will be no air pollution in the world. And there will be green everywhere. There will be a lot of flowers and grass. It will be so beautiful!
Perhaps there will be no wars in the world. The world will be very peaceful and quiet.
I think it will be nice!
