Everywhere man is altering the balance of nature. He is facilitating the spread of plants and animals into new regions,sometimes deliberately,sometimes unconsciously.He is covering huge areas with new kinds of plants,or with houses,factories,slag-heaps and other products of his civilization.He exterminates some species on a large scale,but favors the multiplication of others. In brief,he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million.
选项
答案
人类正无处不在地改变着大自然的平衡。人们有意或无意地使动植物向其他领域扩展变得更加容易。大片的土地被覆盖上了新的各种各样的植物,或者是楼房,工厂,一堆堆的矿渣和人类文明的其他产物。人类使一些物种大规模地灭绝,而又倾向于使另一些物种大量地繁衍。总之,人类在五千年内使地球的生物圈发生的变化远远大于大自然自身五百万年里所发生的变化。
