_________________________________________________答案：
Every day I walk along the Pearl River, I can often see quantities of rubbish such as plastic bags, litter, fruit peels and so on floating on the river. There is no denying that it is the rubbish that results in the dirty water in the Pearl River. As we can see, many people keep on throwing rubbish，so I wonder how this sort of bad habit comes about. On the whole，l am strongly opposed and can't put up with the behavior of this kind，for we have to realize that the earth is facing global warming because of pollution.
On behalf of those who take good care of the environment, I would like to say we can create a beautiful environment as long as we can behave ourselves. There is no doubt that everyone can start from themselves to protect the earth.
