Twenty years from now, the world will be a better place to live in", it is an interesting statement. I agree absolutely. There are lots of problems going on right now, example like: environment pollutions, traffic trams, ect. It makes our life worse day by day. Why in the past, the trees were good, the air was fresh, but now when you go out , the streets are full of dust? Why many years ago, people were so friendly but now they are so insensitive? And if we go on like this, what will happen to the future? so we need to rebalance life and to improve things from now on. We need to solve these problems to have a better life in the future. There are many ways to do that but why we do not do? Everyone can do a little bit to help the world better by small things . Let's start now. Next twenty years, you will live in the world that you want .
