关于地球我们知道些什么人类生活在地球上,但大多数人对地球的了解仍处于蒙昧状态。我们砍伐大片大片的原始森林,我们将工业废水汩汩地排放到江河湖泊中去,我们绞尽脑汁地捕杀动物,我们为制造出原子弹核武器而发动竞赛。无知带来人的狂妄,功利使人忘记一切。美国人曾在一份有关环境问题的报告中写下了这样的警世之句:人类——地球的癌症。 About the Earth What we know about human life on Earth, but most people’s understanding of the Earth is still in a state of ignorance. We deforested large tracts of virgin forest. We ridiculously discharge industrial waste into rivers and lakes. We racked our brains to kill animals. We started the race to make atomic bomb nuclear weapons. Ignorance brings man’s arrogance, utilitarian makes people forget everything. The Americans wrote a precautionary phrase in a report on the environment: human beings - cancer of the earth.
