有关人口老龄化的英语作文(优秀20篇)

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.

In todays world there is no big problem as a population. People began to worry about the support of the earth. And theres probably only standing room for everyone in the future.

The population of Lima is 5. It was 7 million in 1985, but it grew to 9. 1 million in 2000. Tianjin was 790 million in 1985. In 2000, it increased to 9. 7 million dollars. London, Osaka, Moscow, Beijing, Karachi, New Delhi, Jakarta, Seoul and Tehrans population growth has a similar city. Calcutta, Shanghai, New York, St Paul and STO saw a faster population explosion. Tokyo has 18 million 800 thousand in 1985. It became 20 million 200 thousand in 2000. Mexico City had 17 million 300 thousand people in 1985, but in 2000, its population reached 25 million 800 thousand!

What does population growth mean? This means increasing consumption and greater soil pressure. If more people are added to our world, the population has not been warned or taken any action, we will only stand in the end of twenty-first Century.

Each government and the United Nations should see that each countrys population and each city stay for the next 50 years.

Population officials and demographers have much to worry about China’s increasingly aging population. It is estimated that the proportion of people aged 60 or older in China will rise to 11.8 percent in 2020. By the middle of this century, people aged beyond 60 will take up 27.4 percent of the total population — that means one out of every four people will be senior!

The aging population poses a serious challenge to families and the society. On the one hand, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. On the other hand, aging causes a relative decline in working force. Consequently, the productivity of the whole society will be affected to some extent.

The rapidity of the population’s aging has made it more urgent for the adoption of countermeasures. There is no doubt that the key is to build a solid economic foundation. Meanwhile, importance should be attached to overall social progress by changing the backward situation in social security, welfare and service. What’s more, family care and community-based services should also be encouraged.

Given is a table which clearly illustrates the striking trend of aged population in China from 1990 to 2050. During the first 22 years, the number of people aged 60 and above ascended slightly from 97.19 to 136 million, and since 2012 it is predicted that this number will surge remarkably, reaching 410 million in 2050. Meanwhile, the proportion of aged citizens revealed and will reveal the similar trend, and it will reach 27.4% in total population.

(二段版本一：分析老龄化社会问题和挑战)

Such a scenario can be naturally associated with various problems in aged society. For one thing, aged society is best characterized by the more burden for youngsters to support parents, which will enable younger generation to work harder. For another, compared with the past and today, the aged citizens will play a more important role in society. A case in point is their age for retiring will be extended. Therefore, a larger proportion of senior citizens have to take more responsibilities in work, family and society.

Accordingly, it is advisable for Chinese government to focus more eyesight on the coming challenges in the forthcoming future. Meanwhile, it is essential for China to work out comprehensive strategies to strengthen its social welfare to reduce young people’s stress.

Such a scenario can be naturally associated with various problems in aged society, but what resulted in this change above? For one thing, the past 30 years was best characterized by the policy of Family Plan in China, which enabled a host of families to have only one kid and enabled the proportion of youngsters to decline. For another, compared with the past, medical care and quality of life is and will be better; therefore, a larger proportion of people live longer. Consequently, the percentage of aged people showed and will show a trend of rise.

所给是一个表格，清晰展示了中国老龄人口从1990年到2050年的明显趋势。在最初的22年中，60岁以上的人口数量从9719万缓慢增长至1.36亿;自2012年之后，据估计这个数字将飙升，并在2050年达到4.1亿。同时，老龄人口的比例也表现出并且将表现出类似趋势，将达到总人口的27.4%

这样的场景能自然联系到社会老龄化的各种问题。一方面，老龄社会典型特征将是年轻人更多的养老负担，这将使年轻一代更辛苦。另一方面，与过去和今天相比，老年人将在社会中发挥更重要的作用。典型例子就是他们的退休年龄将会延迟。因此，一大部分老年人不得不承担更多家庭、工作和社会责任。

因此，中国政府应更多关注未来的挑战。同时，中国应制定出综合性策略来提升社会福利并减轻年轻人的压力。

(此外二段还可以分析老龄化社会原因)

这样的场景能自然联系到社会老龄化的各种问题，但什么导致以上变化?一方面，过去的30年计划生育政策是个突出特征，这使得很多家庭只有一个孩子，也使得年轻人的比例下降。另一方面，于过去相比，今天的医疗和生活质量更好，将来也会持续更好。因此，很多人们寿命延长。因此，老龄人口的比重表现出并将继续表现出上升趋势。

我国人口老龄化的主要特点是：第一，人口老龄化提前达到高峰。20世纪后期，为控制人口的急剧增长，国家推行计划生育政策，使得人口出生率迅速下降，加快了我国人口老龄化的进程。由于下世纪前半叶人口压力仍然沉重，还要继续坚持计划生育的国策，其结果将不可避免地使我国提早达到人口老龄化高峰。第二，在社会经济不太发达状态下进入人口老龄化。先期进入老龄化社会的一些发达国家，目前人均国民生产总值达到20000美元以上，呈现出“先富后老”，这为解决人口老龄化带来的问题奠定了经济基础。而我国进入老龄化社会时，人均国民生产总值约为1000美元，呈现出“未富先老”，由于经济实力还不强，无疑增加了解决老龄化问题的难度。第三，在多重压力下渡过人口老龄化阶段。下个世纪前半叶，我国在建立和完善社会主义市场经济体制过程中，改革和发展的任务繁重，经济和社会要可持续发展，社会要保持稳定，各种矛盾错综复杂，使得解决人口老龄化问题相对发达国家和人口少的国家更为艰巨。

那么，对于我国的人口老龄化问题我们该怎样去解决呢：中国人口变化的最大特点是“未富先老”，2000年，中国65岁以上老人占人口结构比重为6。8%，与世界平均水平完全一样，至2009年，中国的老龄化比例已达8。3%，显着赶超世界平均水平7。5%。这是中国社科院人口与劳动经济研究所所长蔡昉在中国经济50人论坛2011年年会的演讲重点，“未富先老”将成为“十二五”最重要的挑战。

2004 marks the 10th anniversary of the groundbreaking International Conference on Population and Development (ICPD) in Cairo, Egypt, in 1994.

Ten years ago, on the eve of World Population Day, a new campaign was launched to raise awareness of how international family planning helps save women and childrens lives, safeguard the environment, and slow population growth. 179 governments committed to it when they signed the Program of Action of ICPD, which prescribes the steps that will not only save millions of womens lives but empower（授权, 使能够）societies to achieve a better future.

Today, there are more than 6 billion people on the planet, with half of the worlds population under the age of 25-at or just reaching their childbearing（分娩）years.

Nearly 600,000 women still die each year from pregnancy-related causes. And an estimated 90 percent of infants whose mothers die at childbirth will not survive to their first birthday.

Wild species are becoming extinct 50 to 100 times faster than they naturally would, because of the impact of rapid population growth and increased population density in many countries.

Though population growth is slowing worldwide, more than 90 percent of current growth occurs in the developing world where needs are great and resources are scarce. And these nations have a huge unmet need for family planning services-over 150 million married women of reproductive age in the developing world indicate that they would prefer to postpone childbearing but are not using any method of contraception.

"Girl born today in the developing world faces better prospects than a girl who was born 10 years ago. School enrolment rates are increasing, mortality is declining and life expectancy（平均寿命） is rising, more and more women and couples are able to choose the number and spacing of their children and many countries are taking additional steps to confront HIV/AIDS. But progress is uneven, and in some cases slipping backwards. We need the strength and determination of a marathon（马拉松赛跑）runner to meet our goals during the next decade."

Population control

Progress in science and the improvement of living conditions have led to the rapid growth of the world population. Modern medicine, 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 result, the world population has increased so rapidly that it has now exceeded 6 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, limited productivity and scarce world 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.

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

科学的进步和生活条件的改善有LED到世界人口的快速增长。例如，现代医学，可以使幼儿健康成长，使人们活得更长命。随着生活条件的改善，特别是在农村地区，人们往往会有更大的家庭。作为一个结果，世界人口增长如此迅速，它现在已经超过6000000000。

但人口过度增长对人类社会的存在构成了威胁。大量的人口需要大量的食物供应和住房的空间。然而，有限的生产力几乎不能满足日益增长的人口需求。因此，从长远来看，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，并开展计划生育。只有采取有效措施，人类社会才能稳步发展，有一个光明的未来。

Currently, there is a widespread concern about the previously neglected connection between growing human population and decreasing wild species. As the two graphs obviously portrayed, American population in 1980 was 250 times than that in 1800, a trend accompanied by the extinction of nearly 70 kinds of wildlife in the past 300 years. A clear correlation is suggested that mankind has exerted a tremendously negative influence on natural species.

There are many factors responsible for the aforementioned tendency. First and foremost, to satisfy the space demand for the booming population, the only available solution for Americans is to take occupation of forests and grassland. that used to be habitat of wild animals and plants. Furthermore, the process of industrialization and urbanization has generated severe pollution that essentially destroys environment and ecosystem.

In my point of view, the dearth of wildlife today forecasts an unpromising future for humans tomorrow. In order to eliminate species extinction, relevant laws and regulations must be established and enforced to maintain a large portion of unspoiled areas. Effective measures should also be applied to ensure that the impact of pollution be removed.

目前，人们普遍关注以前忽视的人口增长与减少野生物种之间的关系。正如这两幅图所描绘的，1980的美国人口是1800年的250倍，这是近300年来近70种野生动物灭绝的趋势。一个明显的相关性表明，人类对自然物种产生了巨大的负面影响。

有许多因素负责上述趋势。首先，为了满足人口增长的空间需求，美国人唯一可行的解决办法是占领森林和草原。那曾经是野生动植物的栖息地。此外，工业化和城市化进程产生了严重的污染，基本上破坏了环境和生态系统。

在我看来，今天的野生动物缺乏预测人类没有未来的明天。为了减少物种灭绝，应该制定相关的法律法规和执行保持大部分的原始生态区。还应采取有效措施，以消除污染的影响。

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.

从这两个图,很明显,美国人口的快速增长从1800年到1990年,其野生动物物种的数量不再现有同期飙升。自然,我们可以得出结论,野生动物物种的急剧下降导致的人口增长。

两个原因可以解释这一现象。首先,随着人口的增长,人们消耗更多的自然资源,这常常会导致过度的狩猎。其次,随着人类活动的增加,现代人越来越多的空间。有一个伟大的对其他物种的影响。最后,污染变得越来越严重的问题,随着现代工业的发展。越来越多的动物必须适应的环境或搬到一个完全不同的地方,但并非所有都幸运地在变化中生存下来。

要求解决这个问题,最重要的是,政府的努力来控制人口增长,减少工业污染和提高法律禁止野生动物狩猎。此外,普通公民都应该意识到这种生态危机和野生动物保护的责任。总之,只有当政府和老百姓共同e f堡垒我们希望能找到一个满意的解决这个问题。

problem.China has the largest population, so the one-child policy was necessay. In America, there were 2 billion people 20 years ago, now there were 3 billion. Some day they will have the same amount people as we had in china, will they apply our population control policyAnyway we could be sure they will not critize our population policy at that time.

The human race has experienced a consistent increase in population since the beginning of its history. Famine and disease have done little to offset this steady increase. Too many people are added annually to the population of the world. So both the causes of population increase and the results of having more people are worth careful study.

Culture evolution is the major factor responsible for population increase. Early in human development, people invented tools to hunt animals. Later they built shelters to protect themselves. Step by step, they made life easier. As a result, fewer died from natural forces, such as harsh climate and disease.

In the past, when population grew, there was unexplored territory to inhabit. But now, almost all the habitable land has been explored.From joozone.com.

The worlds population may reach 8.7 billion in 2033. It is clear that world population is a serious issue that needs careful attention. Human beings are unique to solve problems through cultural evolution.Facing the world population explosion in the near future.

首先，随着人口的增长，人们消耗更多的自然资源，这往往导致过度狩猎。第二，随着人类活动的增多，现代人占据了越来越多的空间。对其他物种有很大的影响。随着现代工业的发展，污染问题变得越来越严重。越来越多的动物不得不适应腐烂的环境或迁移到一个完全不同的地方，但不是所有的人都幸运地生存的变化。

一、产生老龄化的原因只有二个：寿命延长和少生孩子。

二、解决老龄化的措施，依据产生的原因不同而有所区别：

1、由于人们的寿命延长而产生老龄化。这是人们生活水平和保健水平提高的必然结果，是民富国强的标志。要解决的问题，不是如何防止老龄化(这是没法防止的，难道将较大年纪的老人杀死?)，而是如何应对由此造成老龄化后所带来的养老金不足和养老服务不足的问题。主要措施是延迟退休和加强养老服务。

2、由于人们少生孩子而产生的老龄化。这是人们生活压力加大和及时行乐盛行的必然结果，是家灾国难的开始。解决的措施只能是充许多生、奖励多生、补助多生。

3、中国的老龄化是由人们寿命延长和少生孩子共同作用产生的。

由于寿命延长而产生老龄化是不可避免的，只能通过延迟退休和加强养老服务，来解决由此造成老龄化后所带来的养老金不足和养老服务不足的问题。

因人们少生孩子而产生的老龄化，是能够通过人们多生孩子来解决的;所以，中国降低老龄化的唯一办法就是充许多生、奖励多生、补助多生;这是解决中国老龄化问题最重要最可行的办法。

由于进入到严重少子化社会之后(年人口出生率低于13。0‰或0～14岁人口占总人口的比例低18%或总和生育率低于1。8)，会造成严重的社会灾难，并且难以恢复到人口的代际均衡的水平;中国在2000年前后就进入了严重少子化社会，就算现在放开生育，也已经难于恢复到世代交替的正常水平了;鼓励生育势在必行，否则，人口快速衰退不可避免!

我国人口老龄化的主要特点是：第一，人口老龄化提前达到高峰。20世纪后期，为控制人口的急剧增长，国家推行计划生育政策，使得人口出生率迅速下降，加快了我国人口老龄化的进程。由于下世纪前半叶人口压力仍然沉重，还要继续坚持计划生育的国策，其结果将不可避免地使我国提早达到人口老龄化高峰。第二，在社会经济不太发达状态下进入人口老龄化。先期进入老龄化社会的一些发达国家，目前人均国民生产总值达到20000美元以上，呈现出“先富后老”，这为解决人口老龄化带来的问题奠定了经济基础。而我国进入老龄化社会时，人均国民生产总值约为1000美元，呈现出“未富先老”，由于经济实力还不强，无疑增加了解决老龄化问题的难度。第三，在多重压力下渡过人口老龄化阶段。下个世纪前半叶，我国在建立和完善社会主义市场经济体制过程中，改革和发展的任务繁重，经济和社会要可持续发展，社会要保持稳定，各种矛盾错综复杂，使得解决人口老龄化问题相对发达国家和人口少的国家更为艰巨。

那么，对于我国的人口老龄化问题我们该怎样去解决呢：中国人口变化的最大特点是“未富先老”，2000年，中国65岁以上老人占人口结构比重为6。8%，与世界平均水平完全一样，至2009年，中国的老龄化比例已达8。3%，显着赶超世界平均水平7。5%。这是中国社科院人口与劳动经济研究所所长蔡昉在中国经济50人论坛2011年年会的演讲重点，“未富先老”将成为“十二五”最重要的挑战。

由于老龄化问题，其情况已越来越多的事实，但日益严重的大多数人带来的问题仍然一无所知。首先，与家庭变得更小，生活的步伐不断升级，甚至更严重的家庭充分照顾岁成员。其次，老龄化导致的人少，以支持增加的老人的劳动人口的相对下降。因此，一定程度上影响整个社会的生产力。第三，也是最重要的是，中国的人口老龄化导致的成功实行计划生育的不同步，与国家的经济进步。

From these graphs, we can draw a conclusion that, with the growth of human population, the number of species has decreased rapidly in America, and some species have even vanished from our planet.

Why does this phenomenon appear? There are several possible reasons for this. Above all, as the human population grows rapidly, a growing number of people came to live where some wild species have been living. Then these species have to move to other places. Some of them probably can not adapt to the new environment and die. In addition, although many people look on the wildlife as their friends, some people may not think so. They catch a lot of wild animals and sell them in order to get more money. Even worse/More importantly, as the result /consequence of the industry, the natural balance and the ecologic environment are destroyed. The clear cutting has become increasingly serious. So some of the wildlife become homeless and extinct.

In order to protect the wildlife, I have some suggestions. First, the governments should make laws to prevent them from being caught and killed. Second, the governments should educate people to love nature and protect it. Third, as for ourselves, we should take practical actions to protect our living environment.

In Britain we are often told that people are leaving the big cities to live in the countryside but is this the case worldwide?

Not at all. If you look at the biggest cities in 1950, seven out of the top ten were in the developed countries but by the year 2000, the developing countries will have eight out of the top ten. New York, which in 1950 was number one with a population of around 12 million, will only be the sixth largest city in the world but with an extra 2 million. And London? London, which was number two, wont even be in the top ten. Its population in 1950, by the way, was about 10 million. And why is this happening? Why are people moving to the big cities from the country in developing countries? The reasons are complex but many are moving to look for work. And the problems this creates are enormous.

The large number of our population has become one of the most serious problems of our society. According to a recent survey of the National Bureau of Statistics, there are more than 1.3 billion people in our country, which account for about 1/5 of all the people in the world. The same survey also predicts that our population will grow quickly in the years to come.

Overpopulation has brought about a series of negative effects to our economic development and social security. In the first place, too many people impose a heavy burden on our environment. As a result, we suffer from a shortage of fresh water and natural resources. In the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. This is a source of social unrest. Last but not least, we have to manufacture all kinds of products to meet the needs of the people, which causes environment pollution to our lakes and land.

Serious though the problem seems, we have to take some measures to tackle it. On the one hand, the government should carry out more strictly the policy of family planning, thus reducing the total number of population. On the other hand, all the people should realize the harms of overpopulation. With the concerted efforts of all the parties concerned, we’re sure to solve the problem in the future.

两个方面含义：一是指老年人口相对增多，在总人口中所占比例不断上升的过程;二是指社会人口结构呈现老年状态，进入老龄化社会。国际上通常看法是，当一个国家或地区60岁以上老年人口占人口总数的10%，或65岁以上老年人口占人口总数的7%，即意味着这个国家或地区的人口处于老龄化社会。老龄问题包括老年人问题与老龄化问题，而老年人问题与老龄化问题相联系，但又不完全相同，一般把有关老年人的社会保障和权益保护看作“老年人问题”，把有关老年人增加对社会经济发展的影响称为“老龄化问题”，这是从人类社会经济发展的范畴来认识老龄问题。

目前，全世界60岁以上老年人口总数已达6亿，有60多个国家的老年人口达到或超过人口总数的10%，进入了人口老龄化社会行列。像古巴、俄罗斯、东欧、芬兰、中国、澳大利亚、还有非洲的一些国家。基本上人多的国家和发达国家占主要。人口老龄化的迅速发展，引起了联合国及世界各国政府的重视和关注。80年代以来，联合国曾两次召开老龄化问题世界大会，并将老龄化问题列入历届联大的重要议题，先后通过了《老龄问题国际行动计划》、《十。一国际老年人节》、《联合国老年人原则》、《1992至2001年解决人口老龄化问题全球目标》、《世界老龄问题宣言》、《1999国际老年人年》等一系列重要决议和文件。提醒各会员国“铭记着二十一世纪的社会老龄化是人类历史上前所未有的，对任何社会都是一项重大的挑战”，吁请各会员国“加强或设立老龄化问题国家级协调机构”，“在国家、区域和地方各级制定综合战略，把老龄问题纳入国家的发展计划中”，“为老龄化社会的来临做好各项准备工作”，提出了“建立不分年龄人人共享的社会”的口号，以期增强人们对人口老龄化问题和老年人问题的重视。

老龄化为什么会成为问题?根据美国普查的研究，世界性的人口老龄化是“历史上未曾出现的社会现象”。人们可以把这一现象当作历史进步来庆祝。从根本上讲，这种人口转变是医疗进步、教育水平明显提高和经济发展的直接成就，也是公共卫生事业，例如饮用水卫生、克服营养不良、克服传染病和寄生虫疾病，以及降低母婴死亡率的结果。
