Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers.

Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.

【参考译文】

全世界的环境问题在变得越来越严重。随着工农业的发展，汽车制造噪音、排放毒气，山上的树木被砍伐，污水不断被排入河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变，环境的巨大破坏已带来负面影响，甚至对人类生存带来巨大威胁。

我们必须面对现实，采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题，大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。

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.

联合国2月28日发布人口报告，2050年世界人口将达到93亿。1804年世界人口总数是10亿，1999年突破60亿。目前世界人口年均增长1。2%，即年增加7700万左右。全世界60岁以上的老人有6。06亿，2050年将上升到20亿。那时，80岁以上老人将达4亿，100岁以上老年人也将有320万。世界人口的历史变化：据科学考证，公元前100万年，世界人口仅1-2万人。在旧石器时代，世界人口翻一番要3万年之久；到公元初，世界人口翻一番缩短到1000年；而到了15世纪中期，世界人口翻一番则缩短为15年。1830年，世界人口达到第一个10亿；1930年突破20亿；1960年达到30亿；

1975年达到40亿；1987年达到50亿；1997年达到60亿！世界人口每增长10亿人，所需的时间分别缩短为100年；30年；15年；12年；10年！世界人口的列车正以越来越快的速度向前飞奔，等待人类的又是什么呢？消费需要的增长，导致了生态失衡：为了养活增加的人口，必须扩大用于生产粮食的耕地和牧场。世界耕地在19世纪初仅有4。5亿公顷（1公顷=1万平方米），其后随着人口的急剧增加，耕地面积也在迅速扩大，现在已达15亿公顷左右，相当于全球陆地面积的10%；另外，牧场面积约有30亿公顷，这样耕地和牧场面积总和占陆地面积达30%，剩下的50亿公顷土地完全是无法利用的沙漠、冻土带，其余是森林。耕地和牧场的迅速增加严重破坏了人类为了自身的生存，垄断性地使用着占地球陆地1/3的土地，这对其它生物来说无疑是一个致命的打击，导致物种灭绝的加速。据世界粮农组织的估计，为了满足人口增长的需要，过量地砍伐树木，以及毁林造田、开辟牧场，使世界热带森林面积每年减少1130公顷，而造林面积只有毁林面积的1/10，致使全球每年损失500-700万公顷的可耕地。城市化的发展，人口日益向城市集中，也使得可耕地大量减少。据联合国人口基金会报告，到2000年，世界上将有一半（即30亿）人生活在城市，为此，居住、交通、工业、市政及其他生活设施的建设占用大量耕地。排污量的增加加重了环境污染和破坏：美国世界资源研究所的一份题为“世界能够得到拯救吗？”的报告中指出，从本世纪初至今，全世界人口增加了3倍，世界生产总值却增长了20倍，矿物燃料使用量增加了10多倍。

1900年-1985年间，全球二氧化硫的年排放量增加6倍，氮氧化物增加10倍，大气中二氧化碳含量增加25%。1990年全世界农药销售额达到500亿美元，是1975年的10倍，由此而带来的一系列恶果是可想而知的。

结核病是全世界最主要的致命传染病之一。世卫组织在3月24日世界防治结核病日，呼吁为全球防治结核病作出新的承诺和采取新的行动。

近些年已取得巨大进展，世界有望实现千年发展目标中所确定的到2015年扭转结核病传播趋势的具体目标。但这还不够。2013年期间，共有900万人患结核病，150万人死亡。

我们显然需要开展更多工作。

在去年5月的世界卫生大会上，各国政府批准了一项为期20年(2016-2035)遏制全球结核病流行的宏伟战略。

根据世卫组织遏制结核病战略的设想，应在全世界彻底消除结核病死亡、疾病和痛苦。该战略确定并阐述了各国政府和合作伙伴的目标和行动，要求提供以病人为中心的医疗服务，实行防治政策和制度，并推动为遏制流行疫情和消除结核病而需开展的研究工作和创新措施。

2015年世界防治结核病日，世卫组织呼吁政府、受影响社区、民间社会组织、卫生保健服务提供者以及国际合作伙伴共同努力推出这一战略，以覆盖、治疗和治愈目前所有结核病患者。

2015年3月24日，是改变做法并加紧全球努力彻底消除结核病的机会。

As is well known by now throughout the world Harvey Ball, a commercial artist from Worcester, Massachusetts created the smiley face in 1963. That image went on to become the most recognizable symbol of good will and good cheer on the planet.

As the years passed Harvey Ball became concerned about the over-commercialization of his symbol, and how its original meaning and intent had become lost in the constant repetition of the marketplace. Out of that concern came his idea for World Smile Day. He thought that we, all of us, should devote one day each year to smiles and kind acts throughout that world. The smiley face knows no politics, no geography and no religion. Harvey’s idea was that for at least one day each year, neither should we. He declared that the first Friday in October each year would henceforth be World Smile Day.

The very first World Smile Day took place in Worcester, MA on October 1, 1999. What a celebration it was! State and local dignitaries gathered and read proclamations in support of the day. Another proclamation recognizing the day was read on the floor of the United States Congress and is now part of the Congressional Record, the reporter of the official proceedings of the US Congress. Thousands of Worcester school children created World Smile Day® cards that were then delivered to area hospitals and nursing homes. The event became national and even international news.

The US Postal service came to Worcester that day to unveil its new Smiley Face stamp design. And, the Postal Service issued a special cancellation just for that event. Each year since then the USPS has issued a different cancellation commemorating the day.

In his inaugural address on that very first World Smile Day Harvey Ball laid the groundwork for that World Smile Day saying that the smiley face “…just reflects what is inside every one of us – a smile is what we want to see when we look at another human being.” He said, “Sometimes we forget that. Sometimes the world seems big and filled with problems that are too hard to understand much less solve. We start to believe that we are too small to make a difference. But that’s not true. The truth is that every one of us has the ability to make a difference every day.”

Harveys hometown of Worcester, MA has been and continues to be the epicenter for World Smile Day.

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.

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

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

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

今年的4月23日，世界读书日，让我深有感触，读书，是一种享受，是一种幸福。著名作家高尔基有一句名言：“书籍是人类进步的阶梯。”书是我的良师益友，是我的好伙伴。读书好比是在和一位高尚的人谈话，的确如此，读书的滋味其乐融融。

读书带给我了欢乐，从书里，大家能学习不少的知识。

书给我留下了深刻的印象;书给我薄弱的课外阅读带来了很大的帮助;所以，书是我学习的好帮手。

书是我成长的好伙伴，为我带来了快乐。

读书不能囫囵吞枣，而是要精读。书告诉我们一点，书里面给我们“保存”着许多欢乐。多看课外书，就能学到许多关于人类或动植物的有关知识。

书是我们学习巨大的力量与成功，如果我们在读书时不用脑子记，不用心记，读书读的很快，到最后一点儿印象都没有了，白花费了很多时间，所以我们不要把读书看做一场游戏，读书是为你而读，不是为别人而读。

1987 年 7 月 11 日，全球人口达到50 亿。为了纪念这个特殊的日子，唤起人们对于人口问题的重视，联合国决定从 1990 年开始，将每年的 7 月 11 日定为“世界人口日”。

站在“7.11”这一人口节点上，回首往昔，我们欣慰的看到：正是中国对人口再生产的“理性革命”，使中国“12亿人口日”推迟了 9 年，使亚洲“30亿人口日”推迟了 3 年，使世界“50亿人口日”推迟了 2 年。中国的人口计生工作不但成就了中国，更成就了世界。

作为“黔滇门户”、“全楚咽喉”的怀化，在这场“理性革命”中，少出生人口 300 万，为建设“美丽幸福怀化”赢得了战略主动权。

展望今朝，实现中国梦的号角正在神州大地嘹亮吹响，人口计生工作迈进了全新的历史关口。稳定低生育水平、促进人口长期均衡发展的任务，仍然十分艰巨。生育观念的转变、出生人口素质的提高、出生性别比的下降、流动人口管理难题的解决、人口老龄化的应对、基层基础工作的加强等等，既是时代赋予的光荣艰巨的重任，更是铿锵前行、不懈奋斗的动力。

我们坚信，有党中央“坚持计划生育基本国策”的旗帜引领，有国务院机构改革中“三个不变”的政策诠释，有全社会的广泛共识和积极参与，人口计生工作必将在实现中国梦的伟大征程中扬帆前行，增光添彩。

“情系育龄群众，服务计生家庭”，是全市本次人口日的主题。“群众”是人口计生事业的永远主角，“服务”是人口计生工作的永恒主题。各级党委、政府都应该始终牢记，铭刻于心。它要求我们在今后的工作中，更加注重以人为本，更加注重优质服务，更加注重宣传倡导，更加注重利益导向，更加注重改革创新……有一种力量，来自你的支持;有一种关怀，来自你的理解。我们真诚地吁吁，全社会一起积极参与到光荣而神圣的人口计生事业中来，共同为建设美丽中国构筑坚固的人口大堤。这是因为，美丽中国是我们的共同家园;人口与经济社会、资源环境的和谐发展，是我们每一个人的梦想!

环境问题 英语作文【1】

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.

With the improvement of our living standard, more and more people can afford a car.

As a result, our roads are more often than not crammed with cars.

However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious.

So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.

By riding a bike, we can not only exercise our body but also protect our environment.

Why not have a try, my dear friends?

Recently,fog and haze has become a imminent threat which most northerners in China are facing.

While the cities of China have greeted striking speed of development with open arms,they suffer greatly from a persistent and dense haze of pollution and smog.

It is high time that we took some methods to protect the environment and ourselves.

Generally speaking,there are three effective ways.

First of all,the government should take into serious consideration the emergency and severity of the air pollution,and take measure to deal with it.

Such as more public transportation systems should be put in use,more energy-saving resources should be utilized.

What’s more,every little effort from individuals counts.

The citizens should contribute to the reduction of pollution by driving less.

Last but not least,try to reduce the time of outdoor activities,especially when the air quality is not good enough.

From what has been mentioned above, to protect our air,we must keep in mind that whatever we give out,we take back in the long run.

So we have to drive less,pollute less and make more changes.

导语：现如今人口越来越多，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

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.

【参考译文】

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

解决这个问题首先需要政府控制人口增长，减少工业污染，加强禁止野生动物捕猎的法律。此外，普通市民应该意识到这一生态危机，承担野生动物保护的责任。总之，只有政府和老百姓联合起来，才能找到一个满意的解决办法。

It has been billed as a hi-tech bike-sharing boom that entrepreneurs hope will make them rich while simultaneously transforming Chinas traffic-clogged cities.

But, occasionally, dreams can turn sour.

In the southern Chinese city of Shenzhen, more than 500 bicycles for hire have been found dumped in huge piles on the streets, according to reports.

Pictures showed jumbled stacks of vehicles nearly three metres high, with handlebars, baskets and other parts scattered on the ground.

City streets around the country have seen an explosion of the colourful bikes that users can rent on demand with a smartphone app and then park wherever they choose.

The sharing economy is taking off in China, where ride-sharing and Airbnb are increasingly commonplace.

From Shanghai to Sichuan province, bike-sharing schemes are being rolled out in an effort to slash congestion and air pollution by putting a country once known as the "Kingdom of Bicycles" back on two wheels.

Companies such as Ofo and Mobike, with their rival fleets of bumblebee yellow and fluorescent orange bikes, have been locked in a cut-throat battle for customers.

But problems have arisen when clients have abandoned their cycles.

"Some people these days just have really bad character," a man named He, who lives near where the stacks appeared, told the Southern Metropolis Daily.

"When theyre done using (the bike) they just throw it away somewhere, because theyve already paid."

In the past few days he witnessed people demolishing the bikes before discarding them on the side of the road, he said.

Residents told the paper that bikes had been piling up over the past week, either parked haphazardly by careless users or stacked by local security guards trying to clear narrow residential alleys and footpaths.

Zhuang Chuangyu, a representative at Shenzhens municipal peoples congress, said the city needed to step up regulation of the bike-sharing industry in order to improve traffic conditions and safety standards, especially since schoolchildren often used the bikes.

In 1980, almost 63% of commuters cycled to work, the Beijing Morning Post reported in 2015, citing government data. But by 2000 that number had plummeted to 38% and today it stands at less than 12%.

Car use, meanwhile, has rocketed. In 2010 China overtook the US to become the worlds largest car market, with 13.5m vehicles sold in just 12 months.
