View of two children

The current family planning policy is unfair, urban residents having only one child, rural residents the first child is female of, can have two children. To have two children, however, leads to the housing problem, population increase, also takes more house, now scientists show that Chinas housing life for 30 years, while western countries housing service life is 2 times of our country, therefore, our countrys house of fast, down too fast, the house is always not enough, so a few people who are facing problems dont have a house to live.

Today, our countrys arable land has also been a lot of problems, such as: 1, due to the large area reclamation woodland lawn, cultivated land is widening. 2, due to the large-scale afforestation, reduce cultivated land quickly. 3, due to water loss and soil erosion, land desertification, human development blindly, arable land decrease quickly. 4, due to the impact of foreign agricultural products, a large number of cultivated land desolate. Because of population increase, to a large number of land reclamation, to a large number of occupation of land, only in this way can we have a new technology, will have a house to live in. So, our countrys land area is greatly reduced. But, our country a lot of land is occupied, can continuously reduce the cultivated land area, arable land decrease, many kinds of food less, even some people starve to death. Two population increase, the employment problem also more and more competition, such as: 1, the our country population base is big, need more employment, employment peak last a long time. 2, needs to improve employment mechanism, talent market, labor market development has yet to be perfected, labor elements configuration has not yet reached full optimization. 3, employment concept updating, lack of initiative entrepreneurial enthusiasm, "such as" "by" the ideas of the "to" still exist, not from their own and realistic environment, employment expectations are too high. So, young people in employment in our country may not work, cant bring home the bacon. In order to themselves and others in the future, please have fewer, eugenics. Boy or girl, is the backbone of the motherland in the future.

对二胎的看法

现在，我国的人数直线上升，因为生二胎人口增多，造成的一系列问题，下面，我给大家加讲一讲吧!

现行的计生政策不公平，城市居民只能生一胎，农村居民第一孩字是女的，能生二胎。可是，生二胎会导致住房问题，人口增多，需要的房子也多，如今科学家证明我国的住房寿命达30年，而西方国家的住房寿命是我国的2倍以上，所以，我国的房子修的快，拆的也快，房子始终不够，因此少数人正面临没有房子住的问题。

如今，我国的耕地也受到了很大的问题，如：1、由于大面积垦林地草地，耕地不断扩大。2、由于大规模造林，使耕地迅速减少。3、由于水土流失，土地沙漠化，人类盲目开发，耕地面积迅速减少。4、由于外国农产品冲击，大批耕地荒芜。就是因为人口增多，才大量的开垦，才大量占用土地，就只这样我们才能有新科技，才会有房子住。所以，我国的耕地面积大大减少。可是，我国大量的土地都被占用，耕地面积就只能不断的减少，耕地减少，种的菜就少了许多，甚至有些人被饿死。生二胎人口增多，就业问题竞争的人也越来越多，如：1、我国人口基数大，需要就业人员多，就业高峰持续时间长。2、就业机制有待完善，人才市场、劳动力市场发育还有待完善，劳动力要素的配置还未达到完全优化。3、就业观念有待更新，缺乏主动择业创业的积极性，“等”“靠”“要”的思想仍然存在，不从自身和现实环境出发，就业期望值过高。所以，我国年青人在就业方面有可能没有工作，就不可以养家糊口。为了自己和他人的未来，请少生、优生。生男生女都一样，都是祖国未来的栋梁。

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。

The first fifty years of the next millennium will be critical for the worlds population. By 2050 population growth should have leveled off, but by then well have 10 billion people--two-thirds as many again as we have today.The rate of population growth is something we can choose right now, though: its not something that just happens, but a matter of human choice. The choice is a complicated one,with many variables, but it remains a choice.

If we want to prevent a population explosion, we should take action now -or assist the poorer countries to do so. They need better government, better institutions, better labor and capital markets, better schools.

Anything that increases the value of womens time and adds to the cost of caring for a child makes a woman less likely to have that child. Since big families are often seen as safety nets for illness and old age, improving poor peoples access to insurance, pensions and welfare institutions also has a major impact. This can be as simple as rural credit, providing a means of saving. Finally, there is education--both for women and, perhaps even more important, for the next generation of children.

These steps are there to be taken, but there appear to be some countries that are not seriously trying at the moment. If we cannot achieve that we will certainly not control population.

That said, I dont feel pessimistic that we are going to run out of resources: we are becoming more efficient at producing food faster than the rate at which population is increasing. There is, however, a risk that we will wreck the environment so effectively that the world will no longer be an attractive place to live. That really would be a dismal outcome, to reach world population equilibrium only to find wed destroyed the natural environment in the process.

翻译：

第一个五十年的下一年世界人口将至关重要。到2050年人口增长应该趋于平稳,但那时我们将有100亿人——我们今天三分之二尽可能多的再次。人口的增长是我们可以选择现在,尽管:这不是刚好,但人类选择的问题。选择是一个复杂的,有许多变量,但它仍然是一个选择。

如果我们想避免人口爆炸,我们现在应该采取行动或者帮助贫穷国家。他们需要更好的政府,更好的制度,更好的劳动力和资本市场,更好的学校。

任何增加的价值,女性的时间和增加了的成本照顾一个孩子会让一个女人更不可能有孩子。自大家庭往往被视为安全网疾病和衰老,改善贫困人口获得保险、退休金和福利机构也有重大影响。这可以简单如农村信用,提供储蓄的一种手段。最后,还有教育,对于女性来说,也许更重要的是,对于下一代的孩子。

有采取这些步骤,但似乎有些国家不认真努力。如果我们不能实现,我们将肯定不是控制人口。

说,我不觉得悲观,我们将耗尽资源:我们正变得更有效地生产粮食的速度比人口增长的速度。然而,风险,我们将有效地破坏环境,世界将不再是一个吸引人居住的地方。这确实是一个可悲的结果,实现了人口的平衡却发现在这个过程中我们破坏了自然环境。

st On January 2016, our country started to carry out two-child policy. It is good

and right for the development of our country now, because our country need more young workers. Many parents also want to have one more child. Althouth they may have some difficulties in affording another child’s life, education and so on, they will have another child to be with them. As for me, the only child in my family, I want to have a sister or a brother. Not only can we share happiness, but also we can help each other in our daily life.

2016年1月,我国开始实施的二胎政策。它是好的

现在对我们国家的发展,因为我们的国家需要更多的年轻工人。许多家长也想要一个孩子。虽然他们可能有困难提供另一个孩子的生活,教育等等,他们会有另一个孩子。至于我,我家里唯一的孩子,我想有一个姐姐或者哥哥。不仅我们能分享快乐,而且在我们的日常生活中我们可以互相帮助。

Nowadays,with the rapid increase of population,the problems of overloading in cities is becoming more and more serious around the world.

For instance,the resources such as education,jobs,health care that a city can supply is limited.So more populations mean that everyone living in the city have less welfare.In addition,the phenomenon of pollution can also be aggravating.And the traffic jams will disturb drives frequently.

In order to deal with the problems caused by overloading,in my opinion,Lowering the birth rate is the essential methods.On the other hand,another way which is executable to reduce the pressure of population in cities is to move people from cities to suburban areas.Of course,this need the help of governments.

In a nutshell,it is time for us to make efforts to control the population timely.

Human Activity and the Earth

There is no doubt that human activity has an effect on the planet. We see the evidence of mankind’s endeavors all around us. While some of man’s accomplishments, such as the building of transportation systems and the consistent supply of potable water, have made Earth a better place for people to live, they have not come without cost. Overall, it seems that human activity harms the Earth more than it benefits it.

For example, the transportation systems that benefit mankind also create pollution and use up valuable energy resources. While we cannot do without transportation these days, we cannot ignore the fact that it has an adverse effect on the planet. Furthermore, those advances that benefit people do not benefit al the life on Earth. Deforestation endangers many animals, and mankind’s great thirst for water and other resources leads to the extinction of many plant forms. In addition, accomplishments such as the supply of potable water to a community are only response to problems that mankind created in the past. It was man that made the water unfit to drink in the first place. Finally, the damage that human activity causes will eventually have a negative effect on people. They will also suffer the effects of pollution and diminishing natural resources.

In conclusion, it seems apparent that man’s activity benefits primarily himself, not the Earth. Moreover, those benefits are only short-term advantages, and man will also suffer the negative effects of his activity in the future. The Earth does not have an inexhaustible supply of resources, so every effort should be made to conserve resources and limit the impact of human activity on the planet.

例如，运输系统对人类有利，却会制造污染，并用尽珍贵的能源。现在我们虽然不能没有运输工具，却也不能忽视运输工具对地球有不良影响的事实。此外，使人类获益的这些进步不一定能使地球上所有生物都获益

环境保护问题英语作文篇一

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.

环境保护问题英语作文篇三

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.

The proposal is from Wang Yuqing, a deputy director of the Committee of Population, Resources and Environment.

He is being quoted as saying he favors a gradual opening of a two-child per family policy, and says he believes the current limitations will be lifted by the end of the five-year plan in 2015.

The current family planning policy was initiated in 1979 to control Chinas rapidly growing population.

But some negative side effects have emerged, including a rapidly aging population.

Peng Xizhe is the Director of the Institute of Population Research at Fudan University.

"The one-child policy has fulfilled the goal initially set. Negative effects will pile up if it continues."

The President of Renmin University, Ji Baocheng, claims the labor force population between the ages of 28 and 40 will be halved in 10 years.

As an example, in Shanghai, which has the highest urban population in China, the number of Shanghai natives -- as in those with a Hukou -- has actually been dropping for the last 17 years in a row, even though the citys population has been increasing.

A possible reason for Shanghai parents not choosing to have a second child could be the rising cost of everyday expenses, particularly the cost of education.

"I dont think Ill have a second child if the limit is removed. Im simply a wage-earner, and I find it difficult enough to raise one child, so I wont consider the second."

But at the same time, there are still people who think it would be nice to have two children.

"I will think about it. A lot of parents now are the only child in families, to have two kids means they can look after each other in the future, and of course, therell be financial burden."

One-Child Policy has been relaxed in certain ways over the years.

In cities such as Shanghai and Beijing, if a couple is both the product of the one-child policy, theyre allowed to have two kids.

Certian ethnic minority groups have been exempt from the rules entirely.

And families in rural areas whose first child is a girl are also allowed to have a second child without punishment.

It remains unclear as to how the proposed two-child policy will work, though its being suggested that several big cities will be selected to try it before its brought in around the country.

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。

the lucky-number has become increasingly popular in daily life of mordern socialty. for example, the number eight means big money which people like most, while the number four means death.

some people believe lucky numbers so deeply that they will afford a telephone with numbers without four and others which is bad in their mind. they argue that the lucky-number really can bring good luck, and, at least, no evidence testify they can not.

as far as i am concerned, there is no such relationship betwwen the numbers and lucky, for the reason that numbers theirself are given certain meaning for the purpose of application of mathmetic. and, in addition, man should not depend on lucky which, in their mind, the numbers gives them.

It is a fact that college is becoming more and more expensive and college life is becoming especially hard for the students who were born in needy families. However, there are several ways in which these students can cover their tuition that their parents are not able to afford. Finding a part-time job, for example, is an ideal way. Besides, one can ask the bank for a loan and repay it when he has the ability. Finally, one can seek assistance from the society.

For me, earning tuition by doing part-time jobs is the most suitable way. First, I learn to be independent both mentally and economically in this way. Apart from this, I no longer need to wor-ry my parents with so heavy a burden. Finally, since I earn my own living, I will be more confi-dent with myself and, therefore, I can live a busy but meaningful college life.

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

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.

As we all know,Chinas mainland population grew to 1.339 billion by 2010,according to census figures released on Thursday,so the government take many action to reduce population.In the most families only have one children,for example me,in my home,my parents only have one children.In fact,I really want to have a brother or sister,because if I have a brother or sister,I will not feel lonely.And if I have some problems,he or she can help me.We can play together and grow up together,when I saw other children play with his brother pr sister in my childhood,I’m admired him very much.Until now,I also want to have a brother,if I have something can’t tell others,I can tell him,and he will protect me.

So in the future,when I have my own family,I will be a parent,I hope I will have two children,one is a boy,the other is a girl.They can accompany with each other,and the brother can protect sister if she have some problems in the outside,and they can study how to cooperate.When they grow up,we will be old,he and she also have many babies,and we will live together very happy.

how to solve the energy shortage（如何解决能源短缺问题）

energy shortage is a very serious problem in the world. many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. this, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind .

on the one hand, most people agree that the problem can be solved in one way or another. one is to conserve and save our energy. energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. most countries have realized the wastefulness in their using of energy. they are trying to conserve energy. for example, some countries have a daylight saving system to use less electricity for lighting. some cities have enforced water savers at public such as restrooms and bars. some have enforced serious penalties on overuse of electricity, water, and farming land. by these means, people hope the drain on energy resources could be slowed down.

however, conservation alone cannot solve the problem. another way, perhaps the best i think,, is to develop new energy resources. obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. i think there are many energy resources that we can develop and utilize. we don’t have to depend only on the current conventional energy resources. there are many other energy resources that we can develop such as nuclear power, waterpower and solar power. these resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.

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.

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。

医疗卫生事业的发展使得人口出生率和成活率迅速提高，死亡率大幅度下降，引起全球人口急剧增长。

世界人口递增的时间越来越短。工业革命时期1800年到1839年，世界人口由10亿增加到20亿，到1960年为30亿，1975年为40亿，1987年7月为50亿。发展中国家占世界人口比重由50年代的66.8%上升到80年代的74.9%。至2000年全球人口增加到61亿，其中85%的增加大多集中在亚洲、非洲和拉丁美洲。

而在未来的30年中，人口增加率将会减缓，到2030年时，世界人口，的总数将为80亿。人口增长率将达到历史性的低点。

从文化教育程度看目前，全球有9.6亿文盲，其中1.3亿儿童。发达许多成绩优秀的高中龄毕业生不愿选择理工等相对艰苦的专业，使得在培养艰苦岗位上所需合格人才陷于困境。发展中国家无力培养更多的人才，而人才从发展中国家向发达国家的流失更加剧了发展中国家的人才危机。以印度为例，到1990年为止，在外谋生的科学家和熟练技术人员达41万，到2000年达54万。

从健康的角度看人口素质，许多疑难病、奇特病的增加表明人口素质的下降。如艾滋病、变异链球菌、奥罗凯病毒、登革热病毒、非典病毒等。正以惊人的速度吞噬人类的生命。

发达国家的人口问题

人口总规模萎缩，人口老龄化。1991年，瑞典老人比重18%，英国16%，日本12%。造成的问题：①社会经济负担加重②劳动力老龄化③生产率低④社会问题多。

发展中国家的人口问题

农业人口多，出生率高，“越穷越生，越生越穷”恶性循环。引发的社会问题是，①贫穷与饥饿②失业③奇型城市化，其后果是失业加剧，人口分布奇型，出现大量工棚区。
