人类人口问题的英语作文（热门20篇）

In this new century 21, there are some "momentum" like tide coming toward us these the people. Brush weibo, QQ chat, grab a red envelope, brush WeChat circle of friends... . But the most popular or families are now talking about "two".

Two-child policy fully opened in 2015, for the policy decision, of course, someone glad someone is sick, and our family, also formed a "two sides" grandma and grandpa insist to have two children, dad neutral, mom, and I? , of course, is opposed to the reason, that is afraid of jumping out of a small one they called bean rivalry with me! Of course, this is the reason of my childhood, but now I grow up, but still hit the bottom of my heart against a second child.

If the second child, cause my family is the most direct economic burden. Circulated online, like a word "two-child policy to stimulate the building potential, stimulates the baby products market price, also stimulate the Australian cows, is not to stimulate our wages." Yes, two children come, will make money not much, but one more eat rice, how it makes family funds flows to come over? One is money, and the other is the effort.

Now most family are three living in the city, and the older generation of either in the local rural or at long distance, the parents go out to work during the day, children go to school, no one in the home, and let the child who is going to take? At that time, the older generation of the grandma and grandpa went out: "you dont have time to raise, we raise!" But what parents really comfortable leaving their kids with their parents.

Another is education. When a life after the second child, dont focus on the childs education, but to make money, some families have not a live, after all is a problem. If there is no education of children, when in the future is also increase the burden?

The last is the health problems. Now many women are already is "women", Eva is risky, as an old saying goes, cherish life, away from the second child.

Since the two-child policy is open, every New Years day is a holiday, relatives to come to the house a guest, and topic no matter talking about east or west, or south or north, will eventually pull back to the "two children" this topic. No matter to talk for hours, they were still relish. Finished talking, you should put the "target" to me.

"Jing art, how are you let your mother give you give birth to a baby brother!"

"Jing art, hurriedly to your mother for a brother and sister, after grow up or have a rely on!"

"......"

I wonder why they are said to have two children so simple, just cut the melon with chopping vegetables. They may never consider the mothers mood and pressure! So, no matter how they "alarmist" I remain the same beginners mind!

在21这个新世纪，不断有一些“势头”如潮流般向我们这些广大人民群众袭来。刷微博，聊QQ，抢红包，刷微信朋友圈…….但最热门还是属现在家家户户都在谈论的“生二胎”。

二胎政策于2015年全面开放，对于这个政策的决定吗，当然是有人欢喜有人忧，而我们家，也形成了“两派”爷爷奶奶坚持生二胎，爸爸中立，妈妈反对，而我呢?当然是反对了，理由嘛，还是怕蹦出个小豆丁和我争宠!当然，这已是我儿时的理由，可现在我长大了，却依然打心底反对二胎。

如果二胎来了，给我的家庭造成的最直接的就是经济负担了。就像网上所流传的一句话“二胎政策，刺激了楼房股势，刺激了婴儿用品的市场价，还刺激了澳大利亚的奶牛，就是没有刺激我们的工资。”是呀，二胎来了，会赚钱的人没多，反倒多了一个吃白饭的，这让家庭的资金如何流动得过来?其一是资金，其二就是精力了。

现在绝大多数的家庭都是一家三口生活在城市里，而老一辈要么在当地农村要么就在异地，白天父母外出工作，子女上学，家里无人，又让谁来带小孩?这时候，老一辈的那些爷爷奶奶就跳出来了：“你们没时间养，我们来养!”可是又有哪些父母真真正正能安心把孩子交给自己的爸妈。

再一个就是教育方面。当一个人生了二胎后，不会再把精力放在孩子的教育上，而是赚钱，毕竟有些家庭养不养的活都是个问题。如果没有在适时的时候教育孩子，那将来不也是徒增负担?

最后一个就是健康问题了。现在许多妇女都已是“高龄产妇”了，生娃都是有风险的，俗话说得好：珍爱生命，远离二胎。

自从二胎政策开放后，每逢过年过节，亲戚来家里做客，话题不管聊到东或西，还是南或北，终究会扯回“二胎“这个话题。不管聊上几个小时，他们还是津津乐道，乐此不疲。聊完了，就该把”矛头“指向我了。

“婧艺啊，你好让你妈妈给你生个小弟弟咯!“

“婧艺啊，赶紧去向你妈妈要个弟弟妹妹，以后长大也好有个依靠啊!”

“………”

我很不解，为何他们都把生二胎说得如此简单，就跟砍瓜切菜似的。他们或许压根没考虑到妈妈的心情与压力!所以，不论他们怎样“危言耸听“我依然不变初心!

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！

The problem of old age is known as one of the most serious problem in todays world. The old people can be seen everywhere. As is shown in the graph, the number of people in the world over the age of sixty will have increased to 600 million by the end of this century. And by the time, there will also be twice as many people over the age of eighty. In the ten years between 1970 and 1980, there was a 23.7% increase in the number of people aged over sixty-five in the industrial world, and an even bigger increase of 38.2% in the developing world.

With the development of economy, the rise in peoples living standards and the improvement of medical conditions, people are living longer and longer. Furthermore, birth rates are falling as the pace of population growth slows down. As a result, the number of old people in the world is experiencing an increase. Though the increase will cause manifold social and economic consequences, we can take effective measures to deal with it. So I believe a bright tomorrow for old people will be achieved through efforts of every person.

【参考译文】

老年问题被认为是当今世界最严重的问题之一。到处都可以看到老年人。如图所示，到本世纪末，六十岁以上的世界人口将增至6亿人。到那时，也会有两倍于八十岁以上的人。在1970至1980年间的十年间，工业世界六十五岁以上人口增加了23.7%，发展中世界人口增长了38.2%。

随着经济的发展，人民生活水平的提高，医疗条件的改善，人们的寿命越来越长。此外，随着人口增长速度放慢，出生率也在下降。结果，世界上老年人的数量正在增加。虽然增加会造成多种社会和经济后果，但我们可以采取有效措施加以处理。所以我相信，老年人的光明明天将通过每个人的努力来实现。

As in modern times of birth control being the basic policy of China,core families made of 3 people in which the parents were born after 1980 have a heavy burden of lives.That is to say,they have parents,father-in-law and mother-in-law,grand parents to care and a child to bring up which means two ones have to care 6 olders and bring up one child.It is such a big burden for a family two of whom are workers, when they have to pay for the housing loan , work and care for the olders.Especilly for those who get married not long ,whose olders coming from countries and having no insurance, the burden is more heavy.

In the tranditional culture of China, married conditions of men are different from women.Generally,men should collect enough money and give a wedding feast.This has accomplished an actuality ,if you have a girl baby,you just have to bring her up,and if you have a boy baby,you have to prepare rather many lots of money which you will have earned all your life to pay for your son’ house and his wedding,besides bringing him up.A jok has described the state lively , your boy baby is called a bank of economic construction you have to construct,while your girl baby is called China Merchants Bank on which you needn’t care too much ,and then someone will invest.As a result ,even if it is allowed to have a second child,families who have had a son would not be willing to have a second one.

Most ones born in 1980s(80s) are singletons which generation had received so much hope and love from their parents.Many coming from rich family are poor in living themselves,and not ready to bear hardships,so that pregnant women in them prefer caesarean birth when they deliver,so as to advoid the serious pain,although it had been proved better in science to bear naturally.The 80s parents even don’t want to pay their attention to the babies who will be taking care of by their grandparents.These mathers don’t want to suffer the pregnant process ,and will be still at the front of the pain,even if they woule like to have second ones.

For the young couples whose ideas are traditional,being like to own a big family,they do like have a second baby,but they can only hang back under the pressure of the cruel reality .For the nation,if it demand contradictions between ageing and low fertility relieved,it should entirely relieve the control of having a second single baby,which will rise the ratio of population steadily.The more important is to have most people share the gain of Reform and Openness,to solve the problem of housing loan of people,turning the commercial residential building into welfare building,to improve and perfect the service system of the society,to improve the medical security ,to narrow the gap between the wealthy and poor,to raise the pay of people.Then, the government needn’t to encourage people to do anything,and they would to have more babies all themselves.

For individual ,if you want a second baby and you are rich ,while your parents have old-age pension and could help bring up baby for you,you may as well have another one.

But if you are in pressure of living,while you parents have no retired pension and are in poor health,you’d better concentrate all your energies on your only baby ,and pay no attention to matter of the second baby ,in which it is the best choice for either you or your baby.

导语：环境问题的英语作文有哪些?以下是小编精心为大家整理的有关环境问题的英语作文，希望对大家有所帮助，欢迎阅读。 环境问题的英语作文篇一

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves. 环境问题的英语作文篇二

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

When I walk on the street, I found most people don’t obey the traffic rules, they just ignore the rules, when there are a lot of people go across the street, they just follow them. It is so dangerous, the accident is very easy to happen, the car will hit the people any time. For the safety, we should obey the traffic rules.

当我走在街上的时候，我发现很多人不遵守交通规则，他们忽视规则，当很多人过马路的时候，他们跟着人群。这是很危险的，很容易发生意外，车子会随时撞到人。出于安全问题，我们应该遵守交通规则。

写作要求：

1.短文开头已给出，不计入总词数；

2.考生可适当发挥，使文章内容充实、连贯；

3.词数120左右；

4. 文中不能出现考生的具体信息。

参考词汇:pave the way

【参考范文】

From the picture we can see a family of three walking on a long red carpet. The son , well dressed, waves proudly in the middle while the father behind bends forward to hold the jacket and the mother in front rolls out the carpet, sweating.

It shows a common phenomenon nowadays that children are the focus of families, shouldering the hope of their parents. Parents arrange everything for their children and spare no effort to pave the way for their success. As a consequence, children become so reliant on their parents that they have no independent thought or creative ideas.

Such a situation is of great concern. In my opinion, overprotection and too much care are extremely bad for children’s development. Instead of doing everything for them, parents should encourage their children to overcome difficulties and inspire them to develop by themselves. Only in this way can they grow up to be independent and become truly successful.

关于交通问题的中考英语作文

With more and more cars coming into our families, we are happy that it has greatly improved our life. But unluckily, it has also brought many problems, such as heavy traffic and traffic accidents.

Traffic safety is everybodys business. We must obey the rules. For example, we must walk on walk side, when we cross zebra – crossing, stop and look right and left, then go across fast. Dont play football on the road .we can tell our parents not to drink before they drive, not to run through red lights, not to talk and laugh while driving etc.

We can say cars are coming into our life, but only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

【参考译文】

随着越来越多的汽车走进我们的家庭，我们很高兴它大大改善了我们的生活。但不幸的是，它也带来了许多问题，如交通拥挤和交通事故。

交通安全人人有责。我们必须遵守规定!例如，我们必须走在一边，当我们过斑马线，停下来，看左，右，然后跨越快速。不要在马路上踢足球，我们可以告诉父母开车前不要喝酒，不要闯红灯，开车时不要说话和笑。

我们可以说汽车正在进入我们的生活，但只有当每个人都认为交通安全是每个人的业务，我们可以安全驾驶道路和人行道上行走。

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.

[人口增长小学生英语作文

Today the quality of our natural environment has become an important issue.

The world population is rising so quickly that the world has become too crowded.We are using up our natural resources and at the same time polluting our environment with dangerous chemicals.

If we continue to do this,life on earth cannot survive.Concerned people have made some progress in environmental protection.

Governments of many countries have established laws to protect the air,forests and sea resources and to stop environmental pollution.Still more measures should be taken to solve environmental problems.

People should be further educated to recognize the importance of the problems,to use modern methods of birth control,to conserve our natural resources and recycle our products.

We are sure that we can have a better and cleaner place in the future.

Better City ，Better life

优质的城市，优质的生活

Environmental problem has become an important and crucial issue. The abysmal lack of fresh water, the desertification, the green house effect and the extinction of creatures are the main issues in environment.

环境问题已成为一个重要和关键的问题。恶化的淡水缺乏，沙漠化，温室效应和生物灭绝是环境的主要问题。

With each second that passes, a water crisis takes another step closer to reality. Consumption of fresh water has tripled since 1950; and fresh water is becoming a very scarce resource. Agricultural practices, mainly irrigation, account for 67% of world water consumption. Over one billion people worldwide dont have access to clean drinking water. So it is incumbent upon all to respect every drop of water and avoid the generation of waste.

随着每一秒的过去，水危机用其他的方法去接近现实。新鲜水用量自1950年以来已经翻了两番;和淡水已成为一个非常稀缺的资源。农业实践，主要是灌溉，为世界用水量67％以上。全世界十几亿人无法获得干净的饮用水。因此，呼吁所有有责任尊重每一滴水，避免废物的产生。

The soil under our feet is also getting away from us. Removal of the natural vegetation leaves extensive tracts of land devoid of a plant cover and susceptible to wind and water erosion. Finally, desertification is accomplished. Four specific activities have been identified as major contributors to the desertification processes: over-cultivation, overgrazing, firewood gathering, and over-irrigation. The extreme seriousness of desertification results from the great difficulty in reversing or even slowing the process. Once the soil has been removed by erosion, only the passage of centuries or millennia will enable new soil to form. The tree planting is a dominant contributor to the development of the disaster. Another effective measure is to restrain the utilization of the land and to exploit the new technology to improve the productiveness of the arable land.

在我们脚下的土地也越来越远离我们。自然植被因为缺乏土地植被和易受风蚀和水蚀而死亡。最后，荒漠化完成。四项具体活动已被确定为对荒漠化的主要导致的过程：过度农垦，过度放牧，薪柴采集和过度灌溉。荒漠化的极端严重性，导致减缓甚至逆转这一过程非常困难。一旦土壤被侵蚀，只有几百年或几千年的才能抵御，使新的土壤形成。主要控制灾情发展都归功于植树。另一个是抑制土地利用率和利用新科技来提高耕地生产率的有效措施。

Our globe is warming up. GHG gases are the main contributor. Carbon dioxide emissions to air are almost exclusively associated with the conversion of energy carriers like natural gas, crude oil, and so forth. Optimization of energy efficiency and, thus, reduction of CO2-emissions and reduction of other GHG emissions contributed from production processes may be the first to be

discussed. And the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation, represents one way of managing a carbon footprint.

我们的地球正在变暖了。温室气体是主要的来源。二氧化碳排放到空气中几乎都是在像天然气，原油等能源载体的转换有关。能源效率，因此优化，二氧化碳的排放和其他温室气体减排贡献减少，生产工艺，第一次将要被讨论。发展减缓碳排放量，如通过太阳能或风能或重新造林的替代项目，代表一个管理方式的碳足迹。

The greed of human beings is using up the plants and animals. Tigers once roamed over most of Asia and we can only see them in the zoo. Whales are once the dominant species in the ocean and now they have got out of our sight because of over-harvesting. We must stop harvesting natural resources to excess and bring them back from the brink of extinction. If we take from the wild we must do it in ways that allow natural populations to recover and last long into the future.

人类的贪婪是使用了植物和动物。猛虎组织一度横跨了亚洲大部分地区，我们只能在动物园里看到它们。鲸是海洋中的一次优势种，现在他们现在已经离开了我们的视线，因为过度捕捞。我们必须停止过度采伐天然资源，从他们来的地方，带来了灭绝的边缘。如果我们在野外，我们必须采取的这样的方式使自然种群的恢复和持续，一直持续到未来很长的时间里。

The earth is not the human’s planet, it is our planet. It’s time to take measures to improve the environment for both humans and other creatures. A safe, clean and sustainable environment depends on more than lip service. Both the government and individuals have the responsibility to minimize direct impacts against the environment. All of us can start planting plants in our home, limiting the use of private cars and using public transportations. And the government should impose necessary standards upon the whole society. The beautiful and vigorous earth will come back soon.

地球不是人类的星球，它是我们的星球。现在是时候应该采取措施改善人类和其他生物的环境了。一个安全，清洁和可持续的环境不是取决于纸上谈兵。无论是政府和个人都有责任，尽量减少对环境的直接影响。我们都可以在我们的家开始种植植物，限制私家车的使用和使用公共交通。政府应强加给整个社会所必需的标准。美丽和活力地球将会很快回来。

As is known to us,China has the biggest population in the world,which is more than 1,300,000,000.Such a large population causes some problems in cities,thats the unemployment.Too many people gather in cities and the jobs are not enough.Some graduates cant find a job though they have left school for years.In addition,traffic jam is another problem resulting from the big population.There are too many cars on the roads and streets.

The situation of the countryside is not good.Too many people live in the countryside and we dont have enough farm land for them.

Fortunately,our government has realized the problems and has attached great importance to them.The government is trying its best to create more jobs and improve traffic systems.Moreover,the one-child policy has helped a lot.

look at your watch for just one minuite.During that time,The popuiation of the world increased by 259.Perhaps you think that is notmuch.Hoever,during the next hour,over15540 more babies will be born on the world.

So it goes on,hour after hour.In oneday,people have to produce food fover 370000 more mouths.Multiply this by365.justthink how many more there will be in one year!What will happen in a hundred years?

The increasing population

may be the greatest challenge of the world today.The worlds population is growing faster and faster.Two thousang years ago,there only 250millon people on the earth. At the beining of the20thcentury,the worldspopulation was about 1.7billion.In 1990,it reached more than five billion.Now at the beininjg of the 21stcentthe worlds population has passed six billion.people say that by the yeay 2010it may be seven billion.That means in about 600 years,there will br standing room only on the earth.Each person will have one half to one square metre of space to live in.There will be hardly enough space ror angbody else.

翻译：

众所周知,中国拥有世界上最大的人口超过1300000000。如此大的人口在城市造成一些问题,这是失业。很多人聚集在城市和工作是不够的。一些毕业生找不到工作,尽管他们已经离开学校好多年了。此外,交通堵塞造成的另一个问题是巨大的人口。有太多的汽车在公路和街道。

农村的情况是不好的。太多的人生活在农村,我们没有足够的农田。

幸运的是,我们的政府已经意识到问题,并重视他们。政府正在尽力创造更多的就业机会,改善交通系统。此外,独生子女政策已经帮助很多。

看看你的手表只有一个秒。在此期间,世界人口增加了259人。也许你认为这是更高的。Hoever,在接下来的一个小时里,over15540更多宝宝将出生在世界。

就这样,一个小时又一个小时。在某一天,人们要生产粮食fov 370000多的嘴。把这个by365。justthink多少会有一年!一百年后会发生什么事?

增加的人口

可能是当今世界最大的挑战。世界人口增长越来越快。述说两年前,地球上只有250米隆人。the20thcentury拜因的,世界人口约为17亿。在1990年,它达到了超过五十亿人。现在的beininjg 21 stcentthe世界人口已经超过六十亿。人们说2010 yeay可能是七十亿年。这意味着在大约600年,地球上只br站立的空间。每个人将有一半生活在一平方米的空间。会有其他几乎没有足够的空间。

Today，pollution has become a serious problem to us. It means that the air，seas，rivers and land are polluted by waste or poisonous things.

It does harm not only to human beings but also to animals .

We cannot have fresh air because many factories have the poisonous smoke sent into the air. Beautiful parks are made dirty by plastic tins and bags.

Fish die from the polluted water. It is said that strange diseases have appeared in some places because of pollution.

I hope scientists can find ways to solve the serious problem.

We are looking forward to seeing the clear sky，clean rivers and beautiful parks again.

Good afternoon, everyone!

We are studying in this school, and it is our duty to keep it clean and tidy. It’s not good to spit in public places, such as in the school library, in the classroom, etc. We should neither draw pictures on the walls nor throw rubbish here and there. I think we must make it a rule to do some cleaning every day. If everyone tried his best to do something useful for our school, I’m sure it will be more and more beautiful.

That’s all. Thank you.

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.

[介绍人口英语作文

(一)全球气候变暖

由于人口的增加和人类生产活动的规模越来越大，向大气释放的二氧化碳(CO2)、甲烷(CH4)、一氧化二氮(N2O)、氯氟碳化合物(CFC)、四氯化碳(CCl4)、一氧化碳(CO)等温室气体不断增加，导致大气的组成发生变化。大气质量受到影响，气候有逐渐变暖的趋势。由于全球气候变暖，将会对全球产生各种不同的影响，较高的温度可使极地冰川融化，海平面每10年将升高6厘米，因而将使一些海岸地区被淹没。全球变暖也可能影响到降雨和大气环流的变化，使气候反常，易造成旱涝灾害，这些都可能导致生态系统发生变化和破坏，全球气候变化将对人类生活产生一系列重大影响。

(二)臭氧层的耗损与破坏

在离地球表面10~50千米的大气平流层中集中了地球上90%的臭氧气体，在离地面25千米处臭氧浓度最大，形成了厚度约为3毫米的臭氧集中层，称为臭氧层。它能吸收太阳的紫外线，以保护地球上的生命免遭过量紫外线的伤害，并将能量贮存在上层大气，起到调节气候的作用。但臭氧层是一个很脆弱的大气层，如果进入一些破坏臭氧的气体，它们就会和臭氧发生化学作用，臭氧层就会遭到破坏。臭氧层被破坏，将使地面受到紫外线辐射的强度增加，给地球上的生命带来很大的危害。研究表明，紫外线辐射能破坏生物蛋白质和基因物质脱氧核糖核酸，造成细胞死亡;使人类皮肤癌发病率增高;伤害眼睛，导致白内障而使眼睛失明;抑制植物如大豆、瓜类、蔬菜等的生长，并穿透10米深的水层，杀死浮游生物和微生物，从而危及水中生物的食物链和自由氧的来源，影响生态平衡和水体的自净能力。

(三)生物多样性减少

《生物多样性公约》指出，生物多样性“是指所有来源的形形色色的生物体，这些来源包括陆地、海洋和其他水生生态系统及其所构成的生态综合体;它包括物种内部、物种之间和生态系统的多样性。”在漫长的生物进化过程中会产生一些新的物种，同时，随着生态环境条件的变化，也会使一些物种消失。所以说，生物多样性是在不断变化的。近百年来，由于人口的急剧增加和人类对资源的不合理开发，加之环境污染等原因，地球上的各种生物及其生态系统受到了极大的冲击，生物多样性也受到了很大的损害。有关学者估计，世界上每年至少有5万种生物物种灭绝，平均每天灭绝的物种达140个，估计到21世纪初，全世界野生生物的损失可达其总数的15%~30%。在中国，由于人口增长和经济发展的压力，对生物资源的不合理利用和破坏，生物多样性所遭受的损失也非常严重，大约已有200个物种已经灭绝;估计约有5000种植物在近年内已处于濒危状态，这些约占中国高等植物总数的20%;大约还有398种脊椎动物也处在濒危状态，约占中国脊椎动物总数的7.7%左右。因此，保护和拯救生物多样性以及这些生物赖以生存的生活条件，同样是摆在我们面前的重要任务。

(四)酸雨蔓延

酸雨是指大气降水中酸碱度(PH值)低于5.6的雨、雪或其他形式的降水。这是大气污染的一种表现。 酸雨对人类环境的影响是多方面的。酸雨降落到河流、湖泊中，会妨碍水中鱼、虾的成长，以致鱼虾减少或绝迹;酸雨还导致土壤酸化，破坏土壤的营养，使土壤贫瘠化，危害植物的生长，造成作物减产，危害森林的生长。此外，酸雨还腐蚀建筑材料，有关资料说明，近十几年来，酸雨地区的一些古迹特别是石刻、石雕或铜塑像的损坏超过以往百年以上，甚至千年以上。世界目前已有三大酸雨区。我国华南酸雨区是唯一尚未治理的。

(五)森林锐减

在今天的地球上，我们的绿色屏障——森林正以平均每年4000平方公里的速度消失。森林的减少使其涵养水源的功能受到破坏，造成了物种的减少和水土流失，对二氧化碳的吸收减少进而又加剧了温室效应。

(六)土地荒漠化

全球陆地面积占60%，其中沙漠和沙漠化面积29%。每年有600万公顷的土地变成沙漠。经济损失每年423亿美元。全球共有干旱、半干旱土地50亿公顷，其中33亿遭到荒漠化威胁。致使每年有600万公顷的农田、900万公顷的牧区失去生产力。人类文明的摇篮底格里斯河、幼发拉底河流域，已由沃土变成荒漠。中国的黄河流域，水土流失亦十分严重。

(七)大气污染

大气污染的主要因子为悬浮颗粒物、一氧化碳、臭氧、二氧化碳、氮氧化物、铅等。大气污染导致每年有30-70万人因烟尘污染提前死亡，2500万的儿童患慢性喉炎，400-700万的农村妇女儿童受害。

(八)水污染

水是我们日常最需要，也上接触最多的物质之一，然而就是水如今也成了危险品。

(九)海洋污染

人类活动使近海区的氮和磷增加50%-200%;过量营养物导致沿海藻类大量生长;波罗的海、北海、黑海、东中国海(东海)等出现赤潮。海洋污染导致赤潮频繁发生，破坏了红树林、珊瑚礁、海草，使近海鱼虾锐减，渔业损失惨重。

(十)危险性废物越境转移

危险性废物是指除放射性废物以外，具有化学活性或毒性、爆炸性、腐蚀性和其他对人类生存环境存在有害特性的废物。美国在资源保护与回收法中规定，所谓危险废物是指一种固体废物和几种固体的混合物，因其数量和浓度较高，可能造成或导致人类死亡，或引起严重的难以治愈疾病或致残的废物。

the ups and downs of population growth

while the problem of the explosively-growing human population has become this century’s focus , the mas s media , during the r ecent decades , have been conveying another sensational is sue near ly to every household — the world’s wildlife extinction . take the u .s . alone for example . during the past one hu ndr ed-odd yea rs , especially f rom 1940 to 1990 , its population has been increasing so rapidly that it has now amounted to 250 million . howeve r , we have, at the same time , surprisingly discovered that the number of wildlife species has been propor tionally decreasing . this is enough to explain what effect“ the ups”of human population has brought to“ the downs”of wildlife population .

investigations so fa r made s how that the extinction of wild animals and c reatur es is att ributed to various r easons , the inc reasing h uman occupa tion of space and environmental pollution being the two impor tant factors obviously k nown to everyone . howeve r , in my mind , nowadays the cruelty of killing and eating wild animals is simply beyond conceivability .

mer ciles s hunters capture them and then sell them for a good price; greedy vintner s try to procur e the best recipes for dressing the meat to pe rfection and con sequently have their restaurants frequented by fine gentlemen; skillful cook s , who under - stand how to oblige the guests , cont rive to make it as expensive as they please; fashion designer s and tailors make the skin into admirable gloves , shoes , handbags , girdles for rich ladies . in this way , the wildlife cont ribute to the feeding , and partially to clothing , of many thousands .

for tunately , the world’s at tention has nowadays been shifted to ecological balance . most people have become aware of the danger of the extinction of wildlife . for the protection of wildlife the government is respon sible, the law is r esponsible, and i should , in the sincerity of my hear t , say eve ry human being is r esponsible .
