As we know, the nature is the most important to human. People depend on the nature to live and human need fresh air, water, vegetable, which al come form the nature. The industry need fuel, raw material, which also root form the nature. What’s more, human also belong to the nature, he is high animal existing in nature. As a consequence, if we destroy the nature, in some extent, we will diminish ourselves.

　　However, human beings haven’t paid more attention to this argument. They upset the ecological balance and destroy the environment surrounding. For example, smoke stacker have disgorged poisonous gases into the atmosphere; factories have dumped waste into rivers and streams; forests have been felled out; citizens haven dumped rubbish everywhere; groundwater have been drawn out unrestrictedly. As the scientists predict, it become dangerous to us if we continue to do so. And in some day, human being will destroy the whole earth and can’t to live any longer.

　　我们知道,人类的自然是最重要的。人依靠自然生活和人类需要新鲜的空气,水,蔬菜,这来自大自然。这个行业需要燃料,原料,也根形成自然。更重要的是,人类也属于自然,他是高的动物存在的本质。因此,如果我们破坏大自然,在某种程度上,我们自己也会减少。

　　然而,人类没有更多的关注这个论点。他们打乱了生态平衡,破坏周围的环境。例如,烟堆垛机石灰有毒气体到大气中,工厂将垃圾倒入河流和小溪,森林被砍伐,公民还到处倾倒垃圾;地下水抽出无限制。科学家预测,我们变得很危险,如果我们继续这样做。在某一天,人类将毁灭整个地球,不能住了。
