人类人口问题的英语作文(热门19篇)

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.

Its estimated that 26 million people will be living in Mexico City by the year 2000, with Sao Paulo in Brazil not far behind.

Last weekend, I wanted to swim in the river that I usually wen in the childhood. When I went there, I was shock. The river is no longer like before. It was full of rubbish. It seemed that the rubbish is from the villagers themselves. In order to put the rubbish nearer, they put all of them into the river. Not only the water is not clean any more, the river also smelt bad. I real touched. Why human and the environment couldn’t live harmonious? Long time ago, they could get along with each other. Why not now? People have to stop their behavior to harm the environment. Otherwise, it would cause destruction to both sides.

上周末，我想去我小时候经常去的那条河里游泳。当我去那里的时候，我很震惊。河水再也不像以前那样了。河里面到处都是垃圾。似乎这些垃圾都是村民丢的。为 了不走那么远丢垃圾，他们把垃圾都丢到河里了。水不仅仅不干净还会散发出臭味。我真的触动了。为什么人类和环境不能和谐地相处呢？很久以前，他们可以好好 相处。为什么现在不可以了呢？人们必须停止他们伤害环境的行为。否则，最后会是两败俱伤。

参考范文：Aging of the Population

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.

参考译文：

人口官员和人口统计学家担心中国日益老化的人口。据估计,在中国60岁以上的人口比例将上升到2020年的11.8%。到本世纪中叶,年龄超过60岁的人将占总人口的27.4%,这意味着每四个人中就有一个将高级!

老年人对家庭和社会造成严重的挑战。一方面,随着家庭变得较小,生活节奏不断升级,甚至严重的家庭照顾年龄成员充分。另一方面,老化导致工作相对衰落的力量。因此,整个社会的生产力将受到影响在某种程度上。

人口老龄化的速度使采取应对措施变得更为紧迫。毫无疑问,解决问题的关键是建立稳固的经济基础。与此同时,应该重视整体的社会进步,改变落后的状况在社会保障、福利和服务。除此之外,应该鼓励家庭照料和社区服务。

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.

As the technology and economic is developing, the environment problem is becoming a severe problem, and the people are seriously affected.

随着科技和经济的发展，环境问题变得严峻，人们也受到严重的影响。

The sustained damage to the environment has caused a serious problem, such as air pollution, sand storm, extraordinary weather, and diseases etc., people suffer from what they have done to the environment.

对环境的持续破坏已经导致了一系列问题，例如大气污染，沙尘暴，反常气候还有疾病等等，人们对环境的破坏让他们尝到苦果。

However. People have realized that it will be too late if they don’t do anything to prevent things from getting worse. For example, there is an “Earth Hour” on a Saturday of March of each year. It is a global movement, usually it lasts from 8:30pm to 9:30pm. It is also called “Light-off for One Hour”. During this hour, all the light will be turned off. The purpose of this movement is not only to save energy, but also to warn the people to realize the importance of protecting the mother earth, and to stop violating the environment.

然而，人们已经意识到，如果他们不做些事情来防止情况继续变糟的话，就太晚了。例如，每年三月的一个周六，有一个“地球一小时”，这是一个全球性的运动，通常从晚上8:30持续到晚上9:30。也叫做“熄灯一小时”。在这一小时里，所有的灯将会被关掉。这个运动的目的不仅仅是节约能源，还警示人们意识到保护地球母亲的重要性，停止对环境的破坏。

Anyway, people and the environment have to keep a balance relationship. People take from the environment, and have to protect it too.

无论如何，人与环境必须要保持一种平衡关系。人从环境索取，也要保护它。

Environmental Protection No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way. There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .

点评：环境问题也是四级作文命题重点话题之一。大学英语四级考试曾经考过Make our Cities Greener.近年来，全球气候异常，造成许多自然灾害的频繁，保护环境刻不容缓，已成为全社会乃至全人类共同关注的热点。

Presently, the world is faced with serious water problems. But these problems witt become more intense and more complex in the future. Our increasing population witt tremendously increase urban waters, primarily sewage. On the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce large volumes of liquid wastes. Many of thesewitt contain chemicals that are poisonous. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever increasing quantities of agriculture chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.

There are two ways by which these pollution problems can be lessened. The first relates to the treatment of wastes to decrease their pollution hazard. This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal. The second approach is to develop an economic use for all or part of the wastes. Farm manure is spread in fields as a nutrient. Wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Liquid wastes from other processing plants may also be used as a supplemental source of water. Only by doing these promptly now can we expect to solve the serious water problems in the future.

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.

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。

范文 (One possible version)

Hello, everyone,

Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.

As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.

It is reported that the world’s population was 6 billion in the year 2,000, and it is growing faster and faster. 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. These problems are mainly in the developing countries because the population of the developing countries is over 4/ 5 of the world’s popuation. So China, the largest developing country, has kept the policy “one couple, one child.”

翻译：

据报道,60亿年世界人口在2000年,它增长得越来越快。世界人口问题是最大的一个,因为它带来了很多问题,比如水资源问题,越来越多的人失去工作,等等。这些问题主要是发展中国家,因为发展中国家的人口超过世界popuation的4/5。最大的发展中国家,因此中国的政策“一对夫妻,一个孩子。”

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.

What Can We Do for the Environment

our environment is becoming worse and worse，what can we do for the environment?I think each of us can do a little bit to help with this problem。

The first thing we can do is to use cloth bags instead of plastic bags when we go shopping. It helps to protect the environment. The second thing we can do is to reuse the old textbooks as possible as we can. We should also never forget to turn off the lights when we leave the classrooms in order to save energy. Whats more，it would be better if we walk or ride a bike to school. We should try our best to reduce pollution and waste。

In fact，even the simplest everyday activities can make a real difference to the environment. I believe we can make the world a better place to live in.

导语：现如今，在高校学生中有一个很热门的讨论话题是他们应该独自在校园外居住还是与室友一起在学生宿舍居住，在这个问题上不同人的看法分歧很大。下面是yuwenmi小编为大家整理的相关英语作文，欢迎阅读与借鉴，谢谢!

Living alone or Living with Roommates

Nowadays, there has appeared a heated discussion among the college students as to whether they should live alone outside the campus or live together with other roommates in the students’ dormitory. Opinions are divided over the matter.

Those who are in favor of Living alone maintain that it is very convenient to live by themselves. They can enjoy absolute freedom in a room of their own. They can have their own timetable without disturbing others. They are also free to equip the room with a personal computer so that they can have easy access to the Internet. From www.joozone.com.

But others argue that living with roommates has attractions of its own. With several students sharing the same room, each person’s experiences can be greatly enriched. They can learn a lot from talking to one another. By learning to tolerate the differences between individuals, they can become more mature.

As far as I’m concerned, I prefer to live with roommates because I love the feeling of belonging. Besides, it is a lot cheaper to live in a dorm than to rent a apartment outside the campus.

现如今，在高校学生中有一个很热门的讨论话题是他们应该独自在校园外居住还是与室友一起在学生宿舍居住，在这个问题上不同人的看法分歧很大。

那些喜欢独自生活的学生认为自己生活很方便。他们在自己的房子里能够享受完全的自由。他们可以随意安排自己的时间而不干扰别人。他们也可以自由的将个人电脑搬进房间，这样他们就可以很方便的上网。

但是其他人则认为和室友同住有它自己的优点。很多人同住一个房间，个人的经历会丰富许多。他们可以在互相交谈中学到许多。通过学习包容彼此的不同，他们会变得更加成熟。

就我自己而言，我更愿意与室友同住，因为我喜欢相处的感觉。另外，住学生宿舍要比在校外租住公寓便宜许多。

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.

此外二段还可以分析老龄化社会原因

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。
