Dear friends,
am writing this letter to call on everyone to pay attention to the present disasterscaused 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. Allthese have sounded an alarm to human beings. So it is high time that we join efforts to saveour planet.
Above all, a task of top priority for us is to plant trees as many as possible, especially inthe arid areas. At the same time, we should stop deforesting in large amount. And we cansave 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 ourplanet. Please join us in the action of protecting our planet. lf you are willing to do somethingto save our planet, please start from the little thing right around you. Thank you!
Sincerely yours
Li Ming
