一封倡议书

　　Dear friends,

亲爱的朋友们，

　　I am writing this letter to call on everyone to pay attention to the present disasters caused by human activities. As some of you may know, over the past years, floods, droughts, landslides, and dust storms have frequented our planet. Not long ago, tsunami swept the Southeast Asia, which caused enormous damage. All these have sounded an alarm to human beings. So it is high time that we join efforts to save our planet.

我写这封信是想呼吁大家关注目前由人类活动造成的灾害。你们有些人可能知道，在过去的几年中，洪水，干旱，滑坡，和沙尘暴时常发生在我们的星球。不久前，海啸横扫东南亚，造成了巨大的损失。所有这些都给人类敲响了警钟。所以现在正是我们共同努力拯救我们的地球的时候。

　　Above all, a task of top priority for us is to plant trees as many as possible, especially in the arid areas. At the same time, we should stop deforesting in large amount. And we can save our planet through many other ways, such as saving water and using recycled paper.

首先，我们首要的任务就是尽可能多地植树造林，特别是在干旱地区。同时，我们应该停止大量砍伐森林。我们还可以通过很多其他的方式来拯救我们的地球，如节约水和使用再生纸。

　　So don’t hesitate to act out these measures. Even a small action is meaningful to our planet. Please join us in the action of protecting our planet. If you are willing to do something to save our planet, please start from the little thing right around you. Thank you!

所以不要犹豫采取这些措施。即使是很小的行动对我们的地球也是有意义的。请加入我们保护地球的行动。如果你愿意做一些事来拯救我们的地球，请从你身边的小事做起。谢谢！

　　Sincerely yours,
　　Li Ming
