A very important world problem is the increasing number of people who actually inhabit this planet. The limited amount of land and land resources will soon be unable to support the huge population if it continues to grow at its present rate.
So why is this huge increase in population taking place? It is really due to the spread of the knowledge and practice of what is becoming known as "Death Control". You have no doubt heard of the term "Birth Control". "Death Control" is something rather different. It recognizes the work of the doctors and scientists who now keep alive people who, not very long ago, would have died of a variety of then incurable diseases. Through a wide variety of technological innovations that include farming methods and the control of deadly diseases, we have found ways to reduce the rate at which we die. However, this success is the very cause of the greatest threat to mankind.
If we examine the amount of land available for this ever-increasing population, we begin to see the problem. If everyone on the planet had an equal share of land, we would each have about 50,000 square metres. This figure seems to be quite encouraging until we examine the amount of usable land we actually have. More than three-fifths of the world’s land cannot produce food.
Obviously, with so little land to support us, we should be taking great care not to reduce it further. But we are not! Instead, we are consuming its "capital" — its nonrenewable fossil fuels and other mineral deposits that took millions of years to form but which are now being destroyed in decades. We are also doing the same with other vital resources not usually thought of as being nonrenewable such as fertile soils, groundwater and the millions of other species that share the earth with us.
It is a very common belief mat the problems of the population explosion are caused mainly by poor people living in poor countries who do not know enough to limit their reproduction. This is not true. The actual number of people in an area is not as important as the effect they have on nature. Developing countries do have an effect on their environment, but it is the populations of richer countries that have a far greater impact on the earth as a whole. [br] Land to support human beings is insufficient because______.
选项
A、most of the world’s land is unusable
B、farm land becomes desert due to climate change
C、populations in poor countries take up greater land
D、the world’s land is not distributed equally
答案
A
解析
根据题干中的Land和support将本题出处定位到第四段首句。题干中的Land to support human beings is insufficient与该句提到的solittle land to support us对应,前一段末句对此进行了解释说明:世界陆地面积大约有五分之三是无法生产食物的,[A]中的most of the world’s land与More than...land对应,unusable与cannot produce food对应,故答案为[A]。[B]是基于常识设的干扰项。[C]在文中未提及;[D]是针对第三段第二句中的If条件句设的干扰项。
