Stop Polluting the River 别再污染这条河了

I am a girl of ten in a primary school. I live near a small river. It was a beautiful river several years ago, and we could see fish in it. But now things have changed. I find some people pouring waste into the river every day. I have told them again and again not to do so, but they don't listen to me, maybe because I'm just a little girl. I think we should think out some ways to stop polluting the river, and call on people to fight against pollution.
我是一名在小学读书的十岁女孩。我住在一条小河附近。几年前，这还是一条美丽的河流，我们能看到河里的鱼。可是现在情况变了。我发现每天都有人向河里倾倒废物。我多次告诉他们不要这样做，可是他们就是不听，可能是因为我是个小女孩。我认为我们应该想出一些办法制止他们污染这条河，并号召人们同污染做斗争。
