我曾看过一个电视节目叫做《科学世界》,这个电视节目叙述的是科学家推测500年后的北美洲海洋,因为地壳运动的变化,陆地和陆地互相碰合,造成海洋被封锁,海水不能流动,那里因为天气炎热海水才容易蒸发得快,过不了多久全部的海水被蒸发了,变成了干旱的土地,一些动物因环境的变化慢慢地进化成了另一种形状,就连性格也改变了,一只性格温柔的松鼠竟变成了性格凶猛狡猾的松鼠了……
I once saw a TV program called "science world", which is about the sea of North America that scientists speculated 500 years later. Because of the change of crustal movement, the land and the land collided with each other, causing the ocean to be blocked and the sea water can't flow. Because of the hot weather, the sea water is easy to evaporate quickly. Soon all the sea water will evaporate and become dry In the dry land, some animals gradually evolved into another shape due to the change of environment, even the character changed. A squirrel with gentle character turned into a squirrel with fierce and cunning character
我还看过一本新编的《十万个为什么》,里面说:“自古以来,古人们都会节约用木头,即使他们去砍树来烧饭做菜也会利用树木,他们只是砍掉一棵树的顶端部,使树木不会断绝生机,让它们还会继续生长,这样就不会毁坏大自然。可是到20世纪90年代初,全球本来100﹪的树木却一瞬间用去了25﹪的树木,那个时候还剩75﹪的树木。从那起,人们就开始疯狂砍伐树木,弄得树木越来越少。美国和英国每天砍伐树木约80亩,这样一来没过多久,全球的树木要全被砍光了!”
