答案

A Letter of Appeal
To everyone on our planet,
Over the past years, floods, droughts, landslides, and duststorms have frequented our planet, the only habitat of human beings. We can"t forget tsunami(海啸) swept the Southeast Asia, which caused enormous damage. All these have sounded an alarm to human beings.
Man has damaged the environment almost to the extent of ruining his own living space. If we pay no attention to the present destructive human activities, our planet will become a tomb instead of a comfortable home. What"s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.
If we want to continue to live in this world, we had better try our best to protect our natural environment. Counter-measures must be taken to stop the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts.
Sincerely yours,
Li Hua
