　　A Letter of Appeal

　　June 13, 2008

　　Dear friends,

　　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.

　　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.

　　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!

　　Sincerely yours,

　　Li Ming
