When I was very small, I lived in my hometown, where I spent a happy childhood. Every day, I went to the small river and caught fish with my friends. The river was so clean that I even could see fish swimming. When winter came, there would be a lot of bird flying in the sky. I looked at the sky and watched them heading south. But now when I go back to hometown, all I see is the trash, which is in the river and the country road. The beautiful nature has been polluted badly. In the small side, people throw rubbish away and cut the trees, thus the green is fading. In the big side, many industries chase the profit at the cost of polluting environment. In order to save the next generation, we need to return green to the world.
