世界上假如没有树怎么办

树是绿色的。它们能减少水土流失，制造氧气，但世界上假如没有树怎么样呢？
如果没有树，沙尘暴会袭来，把整个城市吞没，从此不再纤扮贺有这个城市，而是沙漠，沙子把人们都埋没了，让人死亡。水土流失，就会有泥石流等等的自然灾害，水和泥沙一块从山上冲下来，把人、房子、汽车等冲下来，造成巨大损失。树没了，制造不了氧气，氧气从无限到了有限，人们呼吸完了氧气，没了氧气，人类无法呼吸，窒息死亡。
这上面缺颤三种因素告诉了我们假如没有树我们就会这么样，所以，现在我们要要爱护树木，保护树木，不能毁派让美丽的地球变成那样子！

Trees are green. They can reduce soil erosion, produce oxygen, but if there are no trees in the world how to do?
If there are no trees, dust storms will hit, the entire city engulfed the city no longer there, but the desert, sand, the people are buried, people die. Soil erosion, landslides, and so there will be natural disasters, a water and sediment washed down from the hills, the people, houses, cars and other washed down, causing huge losses. The tree is gone, can not manufacture oxygen, the oxygen from unlimited to limited oxygen that people breathe finished, no oxygen, humans can not breathe, choking death.
This tells us three factors above, if there are no trees so we would like, so now we have to want to care for trees, tree preservation, can not let the beauty of the earth goes like that!

Trees are our good friends. They clean the air and bring us enough oxygen. They help keep the balance of nature. The green leaves and the different gestures of the trees add beauty to our city. With trees,many birds come to our city. They make our life vivid and interesting. We should protect the trees.Don't hurt our friends -- trees.
