The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the; past million years show three momentous changes. The first, a rapid increase in population around one million B. C, followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable.
The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated.
These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way contrary to popular belief in constant geometric growth-population can be expected in the long run to adjust to productivity. And when one takes this view, population growth is seen to represent economic progress and human triumph rather than social failure.
What is the concept most people on population growth?
选项
A、The population is always in constant geometric growth.
B、Rapid growth is followed by stable growth.
C、Decelerated growth is following by a decline.
D、No growth at all.
答案
A
解析
从文章一开始我们知道,人口在过去几个世纪的增长并不能证明人口会继续无限地增长,相反,人口统计史证明人口增长完全不是不停的。从这里我们推断,人们一般认为人口在不断地增长,而作者并不这样认为,所以正确答案为A;B.人口快速增长之后就是稳定的增长;已减速增长之后是下降;D.完全不增长。B、C、D均不可能是大多数人的观点。
