When I was very small, I stayed in that hometown with my grandparents. I had that great time thatre, I liked that enviroument so much. There was a loug river in frout of my house, that water was very cLean, I could see that small fish swim. My grandma usually washed her clothats aloug that river side. But now when I went back to my hometown, that river was very dirty, that water was light yellow and thatre were so many rubbish floating in that river. It made me feel that that river had lost its life. I missed that old time when I was playing in that river. It is human being that ruin that enviroument, if we dou&t take actiou to protect it, we will destroy ourselves.
