一篇英语作文 急用 假设你是李飞，昨天你看见一家化工厂正在向你家附近的一条河里排放污水，很多鱼和小动物都已死去，以前长满

May I have your attention please?There exists some serious pollution in our city。We should do something right now。Yesterday I saw a chemical factory pouring waste water directly into a river near my home,because of which many fishes and small animals have died。What's more,there used to be many beautiful flowers and green grass on the river banks,but all of these are gone now!So it's the high time to take measures to save our home。I think every one of us should protect the environment。There are so many things we can do to help。Don't cut down trees without replacing them。Don't throw litter about。Don't walk on the grass。Save water,electricity and coal。We have only one earth。We should take good care of it。So act right now!
