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.在我很小的时候，我在家乡度过了一个快乐的童年。每天，我都会和我的朋友去小河边抓鱼。河水很干净，我可以看到鱼儿游来游去。冬天来临，会有很多鸟在天上飞，我抬头看着天空，看着它们南飞。但是现在当我回到家乡，在河流和道路上我看到很多垃圾。美丽的大自然遭到严重污染。在细节方面，人们乱扔垃圾，砍伐树木，因此，绿色褪化。在大方面，许多行业以污染环境为代价追逐利润。为了拯救下一代，我们需要让绿色返回世界。
