关于人口增长的问题【13篇】

篇1：世界人口问题

目前，关于人口构成变化的可能影响，主观臆测要多过可靠结论。但这种情形应该会引起广泛的比较研究，而且这种研究可能会对欧洲和中国的政策制定具有非常重要的借鉴意义。

人口普查是当今世界搜集人口资料的一种最基本的科学方法，世界各国都异常重视，但基于国情的不同，各国的人口普查又各有特点。

世界人口结构中，欧洲将持续边缘化

人口构成的这些变化将给政治革新和社会研究带来更大的挑战。

人口构成变化的可能影响，目前还是臆测为主

人口构成变化还将产生其他影响。从农村向城市的地理性移民将会同时向高速发展的城市和遭遇净人口损失的农村提出挑战。比如男女比例失调，在中国，男女新生儿比例为117：100，农村地区这个比例更为悬殊。家庭模式也可能产生变化，比如婚龄推迟、离婚率上升等等，所谓的“第二次人口构成变化”也可能加剧（“第二次人口构成变化”是指同居、单亲家庭、非婚生育以及低生育率等现象大幅度增多，以及更多人不愿结婚和接受约束性行为的传统规范的现象）。

挪威社会学家、联合国教科文组织国际社会科学委员会主席古德蒙·赫内斯认为，目前，关于人口构成变化的可能影响，主观臆测要多过可靠结论。但这种情形应该会引起广泛的比较研究，而且这种研究可能会对欧洲和中国的政策制定具有非常重要的借鉴意义。

世界人口普查

俄罗斯 根据俄罗斯联邦《居民人口普查法》，俄罗斯每十年至少应该举行一次人口普查。人口普查的时间精确到时，即年、月、日、时。20xx年的人口普查是苏联解体后俄罗斯进行的首次人口普查，对于国家掌握居民情况和制定社会发展计划发挥了重要作用。那次人口普查使政府获得了关于人口数量、年龄、性别、婚姻状况、民族成分、受教育程度、家庭副业、就业与收入、住宅状况等资料，既有联邦范围的，也有地区的。最重要的是获得了社会民族结构方面的信息。政府根据这些信息及时调整了国家和地区的社会发展规划。

篇2：关于人口问题的作文

中国是一个发展中国家，面积约为96万平方千米，位居世界第三，而且我国还是世界上人口最多的.国家，位居世界第一，这是我国的重要国情。

据统计，中国每年约有50000人死亡，其中一半死于非命。金鸡年，人口死亡路程上升趋势。中国正在一步步的发展，为什麽人口死亡率却逐年增加？中国现在仍处于贫困时期，随人中国从建国以来一直实行改革开放政策，但却不见成效。（如：1993年，我国国内总产值达5446亿美元，居世界第7位，人均占有量却处在第125位）当触及中国的资源问提时，国人总会骄傲的答曰，我国是资源种类繁多，数量丰富，是世界上的资源大国。殊不知，由于我国人口众多，资源早已被分割的寥寥无几（如：我国耕地在低26位）由于资源分布不均，从而导致有的人占有极少的资源，贫困潦倒，且缺水严重，从而导致许多人渴死，饿死。

中国由于人口众多，曾被称作“骑在自行车上的国家”，现在，虽然家家户户都有了自己的私车，但交通繁忙，很可能导致交通事故，且许多司机“执法而不依法行事”（如：酒后驾车，硬闯红路灯，横冲马路）从而导致许许多多的人死于非命。

我国的工业不仅发达，而且工厂遍布全国各地，人们的环保意识越来越差。截至至今，我国的环境污染，生态破坏仍相当严重。无锡人有一段歌谣，描述了大运河税制的变化：“50年代淘米洗菜；60年代水质变坏；70年代鱼虾绝代；80年代洗不净马桶盖”环境的污染，更是威胁着人类的生命，向肺结核，矽肺病，肺典等不易治疗的病症，像一把锋利的尖刀，刺杀了许许多多无辜的生命。综上所述，是中国死亡人数的主要原因。

我认为，国家应该用可施行的好办法，使人懂得生命的重要性；更好的落实改革开放政策。

我呼吁：保护环境，人人有责！

A closed culture system goes into inevitable decline and even demise. The strong vitality of culture is very closely tied to constant collision, exchange and integration among cultures.

一个封闭的文化系统，必然走向衰落以至死亡。文化强大的生命力与文化间的不断碰撞、交流和融合密不可分。

篇6：人口问题过多英语作文

Everything grows in modern times, and it seems that nothing grows as quickly as population. Population keeps growing, and grows rapidly, firstly because peoples living standards keep going up, with better houses, better clothing, better food, secondly because people know how to preserve themselves so as to live longer, and thirdly

because they have modern medicine and medical care to ensure that usual diseases can be easily cured. There is another cause for the growth of population. Few countries or governments have realised the importance of family planning. On the contrary, some encourage child-birth.

Here are some examples of population growth from 1985 to 2000 (as anticipated).

Lima had 5.7 million people in 1985 but there were 9.1 million by 2000. Tianjin used to have 7. 9 million in 1985. By 2000 its population reached 9. 7 million. Such cities as London, Osaka, Moscow, Beijing, Karachi, Delhi, Jakarta, Seoul, and Teheran are having a similar population growth. We would not be shocked if all other cities have this rate. But some cities, like Calcutta, Shanghai, New York, and Sto Paulo boost their population even more quickly than the above-mentioned cities. Tokyo had 18.8 million in 1985. The year 2000 found 20.2 million Tokyo citizens. Mexico city had 17.3 million people in 1985, but as population specialists had predicted, that reached 25.8 million in 2000 !

The population problem is a universal concern nowadays. Any government is a failure if it does nothing about its population growth.

篇7：解决人口增长英语作文

Progress in science and the improvement of living conditions have led m the rapidgrowth of the world population. Modern medical science, for example, has made it possible for babies to grow up healthily and for people to live longer.With improved living conditions, particularly in the countryside, people tend to have larger families. As a resuit, the world population has increased so rapidly that it has now exceeded 5 billion. But the overgrowth of population presents a threat to the existence of human society. A large population demands a great deal of food supply and shelter space. However,the limited productivity and scarce natural resources can hardly meet the needs of the ever-Increasing population. Thus in the long run, the overgrowth of the world population will only harm mankind.4ia英语作文网

To guarantee the steady development of human society, mankind must realize the consequences resulting from a fast population growth and the importance of carrying out a family planning programme. Only by adopting effectual measures can human society de velop steadily and have a bright future.

控制人口

科学的进步和生活条件的改善导致了世界人口的迅速增长。譬如，现代医学可以使幼儿健康成长，使人们长寿。由于生活条件的改善，特别是农村生活条件的改善，家庭人门日渐增多。结果，世界人口增长如此迅猛以致于现在人口超过了50亿。

但是，人口过分增长对人类社会的存在构成了威胁。大量的人口需要大批的粮食供给和大量的住宅。然而，有限的生产能力和不足的自然资源几乎不能满足日益增长的人口的需要。因此，从长远的观点看，过多的世界人口将会危害人类。

为了保证人类社会的稳定发展，人类必须意识到人口迅速增长所造成的后果和执行计划生育方针的重要性。只有采取有效措施，人类社会才能稳步发展，才会有光明的未来

篇9：英语作文关于人口问题

Population expansion is one of the most serious problems in the world. With better hygienic conditions and better medical care, fewer babies die today. But the birth rate remains unchanged. Moreover, the death rate has been lowered considerably by various kinds of progress. People generally live longer than they used to. All these contribute to a series of problem: shortage of national resources and food supply crowded cities and high rate of unemployment.

To solve all these problems, we must take measures to control birth rate. The first important step is to educate people-to help them understand the advantages of small families. Another important measure is to raise peoples living standards. When people full understand the consequences of population expansion, and when their standard of living is raised, the birth rate will decline without compulsion.

Though it is a difficult task, we should try in a thousand and one ways to carry out birth control If we fail to do so, the world will be too crowded to live in, and the natural resources will be used up. Then we will no longer survive on earth.

人口快速增长带来的问题（图表作文强化练习）

[题目要求]

Directions: Study the following graphs carefully and write an essay in at least 150 words. Your essay should cover these points;

1. effect of the country’s growing human population in its wildlife

2. possible reasons for the effect

3. your suggestion for wildlife protection (15 points)

【参考范文】 the ups and downs of population growth

As is seen from the two graphs, it is clear that with the rapid growth of U.S. population from 1800 to 1990, the number of its wildlife species no longer existing soared during the same period. Naturally, we can draw the conclusion that the sharp decline of wildlife species resulted from the population growth.

Two reasons may account for this phenomenon. To begin with, as the population grows, people consume much more natural resources, which often leads to excessive hunting. Second, with the increase of human activities, modern people take up more and more space. Which has a great impact on other species. Finally, the problem of pollution becomes more and more serious with the development of modern industry. More and more animals have to adapt themselves to the decaying environment or move to a totally different place, but not all of them are fortunate enough to survive the changes.

Solving this problem calls for, above all, the government’s efforts to control population growth, to decrease industrial pollution and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should be aware of this ecological crisis and take on the responsibility of wildlife protection. In a word, only when the government and the common people make joint e f forts can we hope to find a satisfactory solution to this problem

篇12：英语作文人口问题

The two charts show that the increase in the U.S. population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to ecological balance.

As the human population expands, more and more wild animals are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if man is able to share this planet in harmony with other life forms.

In my opinion, it is imperative to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more imporantly, man must learn to stop polluting the environment, or he himself will become extinct.
