有关人口老龄化的英语作文（合集19篇）

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。

It has been estimated that a thousand years ago there were less than 400 million people on earth. However, in the recent thousand years human population has increased nearly 20 times. Nowadays the world population has reached more than 7000 million. The population.

First, a lot of people cant get employment, which is a universal problem in the world. Second, in developing countries there are not enough shelters for too many people and so some people are not properly housed and even are exposed to the elements. Third, in underdeveloped countries a lot of people suffer from hunger because of food shortage, which in turn causes many other problems, malnutrition, disease, etc. Fourth, there are not enough schools for so many people and so a lot of people are illiterate.

Therefore, to eliminate these problems, human beings should take effective measures to control population.

人口问题是当今世界上最大的问题之一，中国是世界上人口最多的国家，如果人口增长过快，将会带来许多严重问题，我们应控制人口增长。

China has a huge population, so the population of china will be very hard to control. Many specialists to solve this problem, but no one have a good

way to solve. Now, the population of china have about 1.3 billion population, and land holdings per head average only 0.82 hectares, also the plough holdings per head average only 0.106 hectares. It take up 43% of the world, so that means the resource of our country is very less now, and didnt surpass the half percentage of the world.

In this article, I will show you some information about the Chinese population policy.

The history of Chinese policy

Start with 1949, china was liberate. The leader of china Mao Zedong was make a policy which is encourage people to bear, because the Mao think a strong country need a huge population. So, in that time if a woman burn many children, then the woman will called “hero woman”.

And many people were born, that is why the population of china were very huge new.

In 1978, the family plan were start to use, because the population of china is too huge, and need some policy to control it. So Chinese government was start to use the family planning to control, that is the most useful way to control, they do many thing like welfare to the Chinese people.

At that time, many of the population were like thispolicy, because they can get much benefit from this event.

I have seen some poster of the family planning in 1978, and I think it is fool the common people in that time. So I always pity for all elderly Chinese

people, and my parent tell me it was very cruel that time. When you born more than one child, you will have much and much punishment from the government, like to injure your house, increase your tax levy, but not cruel as kill you, so Chinese is very kind that time!

Now, the government have been thinking the problem of the population, some peoplesay that we have been keeping the family planning, and other people think we have to stop the family, so it have two choose of family planning, each of it will have a big change in china.

Family planning

Family planning is a kind of population policy in the world which is very common, many country were use this policy to control the population, because it is very easy to use, and very convenient to manage the population. Also is very low-cost to use.

But it have some bad way, like it will have a big problem called aging of population, it made the many young peoples burden very huge, very hard to care two parent or more.

Conclude, family planning isnt the best way to control the population, and it can bring many problem to the country. But we cant find another way to control the population, so we just can use this policy.

The policy of population now

One Chinese leader of family planning department said that we have to keep going for family planning forever, and china need much and much strict family planning to control our population.

Then many specialist to publish their own idea of family planning, all of

ideas were talk about to weaken or stop the family planning, and give some advice of population. Here I would like introduce some specialist ideas.

Chinese population is very large now, if we stop growing immediately, it will have a big problem call aging of population. If this problem happen, the young people will be very hard to provide their family.

Population will be stop growing to 1.8 milliard if we dont do anything, so that is a good way to control the population and dont have much shortcoming. It can be a better way to control the population, isnt it

If we still using the policy of family planning, it will have a large population decrease, and will have aneffect of many thing. Productivity of china will be less, and manpower resource will be less too.

This is all my thinking

Almost every country in the world faced the population

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.

China has already begun to face an aging population. It is reported that by 2003 in China, the population over 65 years of age the proportion of the total population will reach 7%, which will allow China into the United Nations in 1956 set the population aging countries in the world. By 2020, this proportion will be increased to 10.85%, while in 2050, it will reach 20.43%.

At present, the time being will not become the worlds largest country in the elderly population. However, it is the process of aging faster than any other developing country. In fact, China will become the worlds population, one of the fastest aging process, this change brought to China unfavorable factors, it needs China to take a unique way to take care of the aging population.

Respect for the elderly project

In recent years, Chinas economy developed rapidly, with the strength becomes stronger, the state since 1990, security expenses for the elderly are more than 100 billion yuan every year, but also the state was increasing year after year, while also encouraging social and personal fund-raising, donations of non-juvenile welfare facilities set up to address a number of elderly people a sense of security, old age care issues. However, for a big country like China, but also there are other ways to those who need help to provide assistance for lonely elderly people. Care in the community, a warmth of respect for the elderly project in China, the rise of many young people took part in respecting the obligation to engineering work, they not only raised in all directions to bring the material assistance to the elderly, but also for their daily needs and get a wide range of help, thus bringing the warmth and love dedicated to the lonely and helpless old man.

This shows that the "senior citizen project," is Chinas aging population on the eve of a large number of old age to solve the problem of looking into a way to have multiple meanings, which not only brought the Gospel to the lonely elderly, but also carry forward the socialist spiritual civilization.

中国已经开始面临人口老龄化。据报道，到2003年，中国65岁以上人口占总人口的比例将达到7%，这将使中国在1956年联合国世界上人口老龄化国家。到2020年，这一比例将上升到10.85%，而在2050年，它将达到20.43%。

目前，暂时不会成为世界上最大的国家的老年人口。然而，它是一个过程，老化速度比其他发展中国家。事实上，中国将成为世界上人口老龄化最快的一个过程，这一变化将对中国不利的因素，它需要中国采取一种独特的方式照顾老年人。

The world’s population problem is the greatest one because it brings lots of problems, such as water resources problem, more and more people losing their jobs and so on.

老龄化现象The Aging Phenomenon

The Family Plan has been adopted for several years, most of the young generation are only child because their parents follow the government’s policy. Over more than 30years, most family are made up of grandparents, parents and a child. Here comes the problem, the society is facing an aging situation, more and more people are getting old while the young people are less. For a typical family, four grow-ups are at the age of over 40 with a young kid less than 20years old. The aging society is getting more and more obvious, such phenomenon has been catch mass media’s attention. The policy of one child has been doubted, it has been strongly advised that a family is allowed to raise two kids. I totally agree with that, it not only bring happiness to family, but also relieve the pressure of aging problem.

计划生育已经执行了很多年了，年轻一代大都是独生子，因为他们的父母执行国家的计策。30多年过去了，很多家庭是由祖父母，父母和一个孩子组成。问题也出现了，社会面临着老龄化处境，很多人变老，然而年轻人却少。对与一个典型的家庭来说，四个成年人已过四十和一个不到20岁的孩子。老龄化社会越来越突出，这样的现象引起了大众媒体的注意。一个孩子的政策遭到了质疑，强烈一个家庭应该允许有2个孩子。我完全同意，这不仅给家庭带来欢乐，而且减轻了老龄化问题的压力。

Many countries will experience aging populations in the next century because of declining birth and mortality rates. China will soon join their ranks.

As for the issue of aging, its situation has been growing increasingly severe in spite of the fact most people are still ignorant of the problems it brings about. Firstly, with families becoming smaller and living pace escalating, it is even graver for families to care for aged members adequately. Secondly, aging causes a relative decline in working force in that fewer people have to support the increasing aged people. Consequently, the productivity of the whole society is affected to some extent. Thirdly and most importantly, the aging of population in China resulted from the successful implementation of family planning has not been synchronized with national economic progress.

The rapidity of the populations aging has made it more urgent for the adoption of countermeasures. No doubt they key is to build a solid economic foundation. Meanwhile, importance shall be attached to overall social progress by changing the backward situation in social security, welfare and service. Whats more, family care and community services shall also be encouraged.

[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

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.

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。

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."

[世界人口日英语作文

人口老龄化是指一个国家或地区在一个时期内老年人口比重不断上升的现象或过程。人口老龄结构的老龄化是世界人口发展的基本趋势。

人口问题是当今世界人们最为关心的问题之一。人口的发展受社会、政治、经济的制约，同时它对社会的发展也起着促进或延缓的作用。经过30年的努力，我国在人口控制的问题上取得了卓效可喜的成绩。根据国家统计局近期的统计，在计划生育政策实施后，我国人口总和生育率从20世纪70年代初的5.8%下降到现在1.8%左右，这种生育率的下降让我国13亿人口日到来推迟了整整4年。从另一方面来看，随着生育率的下降，人口的发展也使得人口老龄化问题尤为突出。

人口老龄化是指某一人口中老年人口的比重增加，总人口年龄结构发生变化的过程。按国际通用标准，60岁人口占总人口的10%以上，或65岁以上人口占总人口的7%以上，便可以称为“老龄化社会”。美国《纽约时报》指出，我国的老龄化速度太快，从而飞速经过了这个原来西方社会可以建立起一个中产阶级的时间段。联合国的统计数据也表明，我国的老龄化速度是全球最快的。根据我国老龄协会提供的数据，我国老龄高峰将于2030年左右到来，并持续20余年。到2l世纪中期，60岁及以上的老年人可能超过4亿，65岁及以上的老年人则会达到3亿左右。我国人口的老龄化不仅速度是全球最快的，而且这种人口老化趋势也超过了国家经济社会的现代化的发展速度。我国社会的人口是在经济高速发展阶段，人均收入水平低、综合国力不强、社会保障体系不健全的前提下进入老龄化的。这种情况与发达国家老龄化是截然相反的，发达国家的人口老龄化工业化完成之后经济达到高度的发展水平之下才出现。此外，我国人口老龄化还存在着区域失衡的特点。我国各地区老龄化程度自西向东呈阶梯上升，地区间差距较大。东部沿海地区65岁以上老年人口比例已超过8%，其中上海达就到11.46%。而西部地区老年人口比例均在5%以下，部分地区仍是典型的年轻型人口结构。老龄化程度的差异，进一步加剧了地区经济发展的不平衡。因此，老龄化的问题不仅仅是一个人口问题，同时它也成为了制约经济社会发展的问题。

那么，13亿人口大国的养老问题该如何应对?目前，国家有关部门以及众多人口学学者都提出通过完善社会养老保障体制来缓解这股银色浪潮的汹汹来势。但是，我国的社会养老保障体制却面临着资金严重短缺、体制不健全等问题。根据麦肯锡咨询公司预测，我国养老保障的短缺金额到2010年将达1 100亿美元，而未来30年内将会出现3.7万亿的资金缺口。美国战略与国际问题研究中心在研究报告《银发中国——中国养老政策的人口和经济分析》中指出，即使在我国的城市也有近一半的劳动力人口享受不到公共养老体系的保障。全国职工有近3/4的人没有任何退休保障。报告还指出，目前我国的社会养老基金的运作是拆东墙补西墙的现收现付制，即是用现在工人的税来养活目前的退休人员，不做任何基金积累。虽然，目前我国正努力促使“现收现付”制向基金积累制转换，但是由于各种原因，养老基金仍然存在巨大的收支缺口。到2004年，我国全国养老保险欠费达到了450多亿元，在全国范围内，许多省市都面临着养老保险收不抵支的情况，甚至是积累亏空。加之农村养老问题也日益提高到政策议程上来，我国的养老保障制度面临着艰巨的挑战。

[关于人口老龄化的作文

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.

It has been estimated that a thousand years ago there were less than 400 million people on earth. Today, however, the worlds population has amounted to 5,000 million. What is worse, it keeps growing at a surprising speed. If this trend continues, the worlds population will shoot up to 7,000 million by the year 2000. This is what we call population explosion.

The rapid development of science and technology is the main cause of population explosion. We can see that the population has been growing at a tremendous speed since the Industrial and Agriculture Revolution in 1650, which raised the peoples standard of living, and the emergence of modern medicine in 1550, which lowered the peoples death rate.

Population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment. It is time that we acted quickly to carry out the policy of birth control otherwise, mans survival on the earth will be threatened.

【参考译文】

据估计，一千年前地球上只有不到4亿人。然而，今天，世界人口已达50亿。更糟糕的是，它以惊人的速度持续增长。如果这种趋势继续下去，到2000年，世界人口将增长到70亿。这就是我们所说的人口爆炸。

科学技术的迅速发展是人口爆炸的主要原因。我们看到，自1650工农业革命以来，人口数量以惊人的速度增长，人民的生活水平提高了，现代医学的出现在1550，人民的死亡率下降了。

人口激增会导致食物短缺、住房短缺和失业等许多问题。该是我们迅速采取实行计划生育政策的时候了，否则人类的生存将受到威胁。

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.
