当今社会正以迅猛之势飞速发展,归根到底是高新技术产业的进一步深化。不容乐观的就是环境与发展之间的问题还没有得到彻底根除。而下面便是小编整理的关于环境问题英语作文 。

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.

环境问题 英语作文【2】

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?

环境问题 英语作文【3】

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.

济南市环境保护委员会的叔叔阿姨们:

您们好!

暑假期间,我跟随父母去大明湖游玩,所见所闻一直印在了我的脑海里。美丽的大明湖中,荷花盛开,千姿百态,真不愧是“四面荷花三面柳,一城山色半城湖”呀!我陶醉了!但这时,猛然看见一位游客将一块糖果的包装纸扔到了湖水中,而不远处就是垃圾箱;甚至还有几位游客随手将荷叶和荷花摘去。虽然有管理人员劝说,可是他们还是满不在乎。荷叶根部漂浮的垃圾,靠近岸边的被摘去的荷花、荷叶深深地刺痛了我的心。因此,我想提出几点建议:

一、可以开展一些文艺活动,通过演出的形式来教育那些不爱护环境的游客;

二、与游客做一些小游戏,如环保知识问答等,并给予小奖品,让人们认识到环保的重要性;

三、组织志愿者每周打扫大明湖的环境卫生;

四、开展“我爱大明湖”摄影比赛与征文比赛,唤起人们对大明湖的热爱;

五、号召小学生组成义务宣传队,通过宣传为泉城尽自己的一份力量;

六、设计一个“曝光台”,曝光有些人的不文明行为。

亲爱的叔叔阿姨们,泉城是我们的家,大明湖是我们泉城人的骄傲。让我们行动起来,保护我们的家园,爱护令我们骄傲的大明湖,好吗?

篇9:有关保护环境文章

全文共 986 字

+ 加入清单

世界各国中,要想在国际中树立威望,就必须加大力度发展本国的经济。在工业的生产中,人们似乎忽略了环保这个事情,一心只想在经济利益中受益。你别以为你没有吃亏,你在经济中受到一份利益,就会在环保上吃一份亏。日积月累,吃亏的最后还是自己。

新中国成立后,中国工业突飞猛进,经济值年年提高很多,在国际中的地位也慢慢上升,可是环境的破坏程度也越来越大。所以说既要发展迅速,又要环保,就不得不走可持续发展道路。

既然是要走可持续发展道路,就必须按条理进行。不能先开发、后治理,必须以“防”为主,防治结合,综合治理;谁开发、谁保护,谁污染、谁治理。单单靠个人是无法达到预计目的的,也必须依靠群众的力量来保护环境。

让我们共同努力创造我们美好的生活吧!

古往今来,地球妈妈用甘甜的乳汁哺育了无数代子孙。原来的她被小辈们装饰得楚楚动人。可是,现在人类为了自身的利益,将她折磨得天昏地暗。人类只有一个地球;而地球正面临着严峻的环境危机。“救救地球”已成为世界各国人民最强烈的呼声。

我为周围环境的恶化而感到心痛,我想:作为未来接班人的青少年,如果不了解人类环境的构成和环境问题的严重性,无视有关环境保护的法律法规,不去增强环境保护意识,自觉履行保护环境的义务的话,我们的生命将毁在自己的手中,老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境,保护我们这个赖以生存的家园,做一个保护环境的卫士。

据我收集到的一份报告说:“环境问题是由于人类不合理地开发和利用自然源所造成的。触目惊心的环境问题主要有大气污染、水质污染、噪声污染、食品污染、不适当开发利用自然资源这五大类。”一个个铁一样的事实告诉我们,它们像恶魔般无情地吞噬着人类的生命。它威胁着生态平衡,危害着人体健康,制约着经济和社会的可持续发展,它让人类陷入了困境。为此我作出宣告:“只要我们——人类有时刻不忘保护环境的意识,有依法治理环境的意识,地球村将成为美好的乐园”。未来的天空一定是碧蓝的,水是清澈的,绿树成荫鲜花遍地,人类可以尽情享受大自然赋予我们的幸福。

“真正检验我们对环境的贡献不是言辞,而是行动。”虽然我现在做得只不过是一些微小的事,但是我坚信要是我们人人都有保护环境的责任心,从自己做起,从小事做起,携手保护我们的家园,自然会给人类应有的回报。在温暖的摇篮——草原上小憩;在慈祥的笑脸——天空下成长,在爱的源泉——河流中沐浴

篇10:环境问题

全文共 2090 字

+ 加入清单

当前,威胁人类生存的十大环境问题是:

(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。

People who love traveling are always finding places to take a vacation, which caused a lot of troubles.For example, I found that some people were used to dropping out the trash everywhere. They just regarded the sightseeings as their houses, which cost a lot to clean it up. Besides, some one should write down their names on the trees and walls. People who wanted to leave their names whereever they went are always to punish in future.

Nevertheless, I also found some good examples, such as teaching tourists not to destroy the places of historic interests, helping clean up the environment,etc..I think we all need to teach more people not to hurt our precious nature. What we really need to do is protect them form destroying.

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

妈妈首先发言,“现在的环境不太好,可以说是很差,PM2。5很严重,很多人外出都要带口罩!”爸爸也深有同感:“哎呀!现在环境是不好,污水都排放到河里,你看我们小区里的那条河呀,散步时都臭气熏天。”“我同意!我同意!我带米拉(我家养的小狗)下去遛弯时,都要捂着鼻子。那闸门不开时,水很少而且是乌黑的,石头、死鱼都露出水面,散发着一阵阵恶臭,”我生气地说道。妈妈无可奈何道:“造成环境不好的原因主要还是人们环保意识不强,在发展经济的同时,忽视了对环境的保护。逢年过节时,人们大量购买烟花爆竹,节日气氛虽然增加了,但同时也对环境造成了极大的伤害。”爸爸接着说道,“我很赞同妈妈的看法,我们家每年都不放,一家人聚在一起,也一样有过年的气氛。”我嬉皮笑脸地说:“就是呀!别人家放,我们远远地看,还更清楚、更漂亮呢!”“汽车排放的尾气也是污染环境的罪魁祸首,”妈妈意味深长地说,“但是,我们生活中又离不开汽车。现在大家的工作、学习都很紧张,不开汽车将会浪费很多时间在路上,所以我们只能尽量少开车,休息日多骑骑自行车……”没等妈妈说完,我调皮地边笑边说,“哈哈!别忘了我们还有‘11’路呢,这样既能锻炼身体又能保护环境。”

为了你爱的人和爱你的人,就让我们一起来保护地球这个大家庭的环境吧!

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.

3.为了保护地球有限的资源,我们应该采取什么措施呢?请根据下面的提示写一篇约80词的短文,短文开头已经给出。提示词;1.save water,the source of life,protect drinking water,stop polluting,make full use of it;2.save electricity,crucial,turn off,other electric machines;3. save forests,useful,stop cutting down;4.recycle useful rubbish,save resources

参考作文:

Although the world develops much faster and better,the resources on the earth get fewer and fewer.In order to protect them,something must be done.

Save water. Water is the source of life. No water,no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it,but also make full use of it.

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper,bottles,and so on.

We can save resources in this way. I believe we can make the world a better place to live in.

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。

导语:地球是我们从后代手中借来的、环保不分民族,生态没有国界不要旁观,请加入行动者的行列今天节约一滴水,留给后人一滴血。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!

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。
