18. Dear Editor, I’m a student at a Shandong middle school. My hometown used to be a beautiful place. Thick forest and green grass could be seen everywhere. However, because of climate changes, it rains little now. In order to build houses and grow more crops, people there cut down more and more trees. As time went on, the forests were seriously destroyed. As a result, sandstorms struck us now and then, from which people suffered a lot. To prevent the process of desertification, I hope that all the people take good care of the forest and plant more trees instead of cutting them down. Then our living conditions will soon be improved.
