人口过剩

On the other hand, more and more people are becoming alarmed about the dangers of overpopulation.

另一方面，越来越多的人们正警觉到了人口过剩的危机。

Some of the great dystopias of the past – I think of John Brunner's novels from the early 1970s– centered on what was then the alleged nightmare of overpopulation; but that was a modernist nightmare, and what we confront today is perhaps not a dystopia either, but rather a certainty lived in a rather different way and with a properly postmodern ambivalence; which at any rate distinctly forecloses the possibility of progress or of solutions.

一些过去的伟大的反乌托邦作品——我想到20世纪70年代约翰·布鲁纳的小说——曾集中描写当时公认的人口过剩的梦魇；但那是现代主义的梦魇，而我们今天所面对的也许不是反乌托邦的，而是以一种相当不同的方式实际经历的东西，带有真正的后现代的模糊性；它俨然排除了进步或解决的可能。

In all ages, the issue of population overmuch have never been that standing out.

历史上，人口过剩的问题从来没有比现在更加突出。

Hand in hand with this we must frankly recognize the overbalance of population in our industrial centers and, by engaging on a national scale in a redistribution, endeavor to provide a better use of the land for those best fitted for the land.

与此同时，我们还必须认识到工业中心已经人口过剩，因此应尽力把土地提供给最善於耕种的人，一方面使土地得到更好的利用，一方面在全国范围重新分配人口。

But the overgrowth of population presents a threat to the existence of human society.

但是人口过剩对人类社会的存在造成了威胁。

In history, overplus of population is outstanding question even than any other period before.

历史上，人口过剩的问题从来没有比现在更加突出。

Here the country is overpopulated, so everybody gives in.

这个国家人口过剩，所以每个人都容易向现实屈服。

No wonder the world was getting overpopulated—with such pressure at the elemental urge within every individual!

怪不得世界上越来越人口过剩-在这种压力下，在元素促请内每一个人！

Since to provide increased goods and services for more people does require technological advances, capital investment, and skilled labor, there must be a point beyond which an increase in population leads to a lowering of real income and a decline the level of well-being, Thus it came to be said that when a population should experience in the long run an ever-falling supply of goods and services, per capita, it was no longer of best size.

既然为更多的人口提供更多的商品和服务确实需要技术进步，资本投资和有技术的工人，那么总有那么一个限度，如果人口增长超过这个限度就会导致国民实际收入的减少和生活水准的降低。因此，有人提出，如果一个国家的人民长期以来的人均商品供应和服务水平不断下降，这个国家就已经人口过剩了。
