In the past hundred years, there have heen frequent natural disasters, such as floods, droughts, mud-rock flows, seismic sea waves, earthquakes, windstorms and the stretching of new deserts. The disasters have killed millions upon millions of people, destroyed countless homes, and wiped out numerous pieces of fertile land.

Now more and more people become aware that those disasters have much to do with what we have done to the earth. We have cut down too many trees in the forests,we have badly polluted the environment, we have shocked our own home-planet time and against with tremendously powerful explosions of nuclear bombs. As a result, climates have become abnormal, rainwater rushes down hillsides angrily, and the underground energy goes up to revenge itself on us.

The earth is our only home-planet. It is urgent for us to stop damaging it, and to do our best to protect it and make it a lovely place suitable to live in, for we have nowhere to go and survive except where we are now.

在过去的一百年，有频繁发生的自然灾害，如洪水，干旱，泥石流，海啸，地震，风暴和新的沙漠延伸。灾害杀害了成千上万的人，摧毁了无数的房屋，摧毁了许多块肥沃的土地。

现在越来越多的人意识到这些灾害都与我们对地球所做的有关。我们在森林中砍伐太多的树木，严重污染环境，我们已经让自己的家园震惊了，我们要与极度强大的核弹爆炸对抗。结果，气候变得异常，雨水一气之下冲下山坡，地下能量升起用它自己来报复我们。

地球是我们唯一的家园地球。因此，当务之急就是停止破坏它，并尽力保护它，使它成为一个可爱的适合居住的地方，因为除了我们现在生存的地方，我们已经无处可去。
