The world is changing all the time, and my hometown is no exception. In recent years, my new eyes have witnessed the welcome changes in my hometown.

The mountain in the hometown changed, the former bald "steamed bread", now green oil; The water in my hometown has changed. Once full of mud and mud, the water is now crystal clear. The road in my hometown has changed. Once the muddy dirt road, now not only became the spacious asphalt road, but also repaired the traffic light; The house in my hometown has changed, and  bungalow, formerly short and small, is now a spectacular high-rise building. The transportation tool in my hometown has changed. Once upon a time, it was the goal of the people to have a bicycle, and now the streets are almost all beautiful cars. The clothes of the family changed, and there was a patch on the clothes of the old people. In the past, there was another saying, "three years, three years, three years of sewing." And now, peoples clothes are colorful, fashionable, there are suspenders, suits, skirts, dresses, and so on, very beautiful...

My hometown is changing day by day.

Home is changing little by little.

I opened my eyes wide, observed carefully, searched carefully, and carefully found... I wish I could change all the changes of the mountains and rivers of my hometown, and put them all into my mind and become a part of my beautiful memory.

Once upon a time, there was nothing at the edge of the Yellow River.

Now, the yellow side construction is very good, there are a lot of colorful lights on the Yellow River, there are a lot of lights on the bridge, the bridge is also full of colored lights, some of the bridge also has spotlights!

The sculpture on the edge of the Yellow River is also beautiful, with the Yellow River mother, the tang priest in the journey to the west, and so on, the statues are all vivid, as if they were real.

The most beautiful is the music fountain. The music fountain has a acoustics next to it. It has a wonderful music. The fountain will go up and down with the music rhythm. The pool also has colorful lights, very beautiful.

When the foreigner came to lanzhou, they said that the Yellow River was comparable to the bund in Shanghai.

Once man did not have to think about the protection of his environment。 There were few people on the earth, and natural resources seemed to be unlimited。Today things are different。 The world has bee too crowded。 We are using up our natural resources,and polluting our environment with dangerous chemicals。 If we continue to do this, human life on earth will not survive。 We realize that if too many fish are taken from the sea, there will soon be none left。 Yet,with modern fishing methods, more and more fish are caught。We know that if too many trees are cut down, forests will disappear。 Yet, we continue to use powerful machines to cut down more and more trees。 We see that if rivers are polluted with waste products, we will die。 Yet, waste products are still put into rivers。

过去,人们不必担心保护环境的问题。因为那时地球上人口稀少,自然资源似乎取之不尽。如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。我们都明白如果从海里捕捉太多的鱼,海里就不会再有鱼了。可是,现代化的捕鱼技术使得捕鱼量越来越大。我们都明白如果砍伐太多的树木,森林就会消失。可是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都明白如果河水被废弃物污染的话,我们仅有死路一条。可是废弃物仍然源源不断地进入河里。

We know that if the population continues to rise at the present rate, in a few years, there won't be enough food。What can we do to solve these problems?If we eat more vegetables and less meat, there will be more food available。 Land for crops feeds five times more people than land where animals are kept。Our natural resources will last longer if we learn to recycie them。The world population will not rise so quickly if people use modern methods of birth control。

我们明白,人口继续照此刻这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢?如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。如果我们学会再利用的话,自然资源就能持续更久。如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future。

最终,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。

In the 21st century, humans science economic development has reached a very high level. But I want to ask: do you have any aware of human activities on the environment will be what kind of impact?

The deforestation of the forest is not a serious problem? According to the survey the world forest area is in at an annual rate of millions of hectares of disappear. Caused a lot of water and soil loss, make many areas become desert. Scope of human activities in the declining, its not scary?

What human besides destroying forests, dont damage the environment problems? It is not. Now, we should see the seriousness of water pollution. At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

In the discharge of smoke in the factory, we dont know the smoke is atmospheric pollution? Scientists have found that there are at least 100 species of air pollutants produced great harm to the environment, directly affect peoples health.

Do we want to live in such an environment? Certainly dont want to; Then let us use action to prove it! We can start from me, start from now, start from the side. Love nature, the consciousness of environment protection! To do propaganda environmental protection angel! Lets take action to protect the environment

在21世纪的今天,人类的科学经济发展已经达到了很高的水平。然而我想问:你们有没有意识到人类的活动对环境会造成怎样的影响呢?

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失,使许多地区成为沙漠。人类的活动范围在不断减少,这不可怕吗?

人类除了破坏森林之外,难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性,目前世界上60%的地区面临供水不足,已有20%的人口难以得到清洁水,51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的,现在的工厂及我们生活中的污水,没有通过处理就排出去。这不是最好的证明吗?据研究,每排放1立方米污水,就污染14立方米天然水。想一想,这是多么可怕的数字?

在工厂排出的浓烟里,我们不知道浓烟是污染大气的吗?科学家发现,至少有100种大气污染物对环境产生极大危害,直接影响人们的健康。

难道我们想在这种环境中生活吗?当然不想;那让我们用行动来证明吧!我们可以从我做起,从现在做起,从身边做起。树立爱自然、爱护环境的意识吧!来做宣传环保的使者!让我们一起为保护环境行动起来吧

尊敬的校领导:

你们好!

早晨,伴着冉冉升起的朝阳,我来到了这个美丽的学校;下午,夕阳亲吻西山的时候,我与校园挥手告别。久而久之,我与这个美丽的校园相处了六年了。同时,对这个学校有着浓浓的感情。

在这个美丽的校园,也有几处“丑陋”的地方。吃完午餐后,同学们你追我赶的玩耍,留下的是堆积如山的一次性木筷。学校的洗水池里,哗哗流淌的自来水正在悲伤的哭泣。上课后,操场上的纸飞机、纸球清晰可见…

为了让校园更美丽,我提出以下建议:

1、开展“节约一滴水,节约一度电。”活动,通过多种方式让同学认识到浪费、污染很可耻,愿意加入到节约资源的行列中。

2、在学校加强环保管理。对爱护环境、不乱丢乱扔的班级做出适当的奖励,对不良行为做出批评。

3、定个日期作为环保日,既可以保护校园环境,又可以让保护环境的观念铭记心间。

人类一直以为地球上的所有资源都是取之不尽的,没有担心过自己所做的一切是否会对地球造成伤害,从不担心把千万吨废气送到天空去,又把数以亿吨计的垃圾倒进海洋。大家都认为世界这么大,这一点废物算什么?我们错了,其实地球虽大,但生物只能在海拔8千米到海底11千米的范围内生活,而占了95%的生物都只能生存在中间约3公里的范围内,人竟肆意地从三方面来弄污这有限的生活环境

海洋污染:主要是从油船与油井漏出来的原油,农田用的杀虫剂和化肥,工厂排出的污水,矿场流出的酸性溶液;它们使得大部分的海洋湖泊都受到污染,结果不但海洋生物受害,就是鸟类和人类也可能因吃了这些生物而中毒。

陆地污染:垃圾的清理成了各大城市的重要问题,每天千万吨的垃圾中,好些是不能焚化或腐化的,如塑料、橡胶、玻璃、铝等废物。它们成了城市卫生的第一号敌人。

空气污染:这是最为直接与严重的了,主要来自工厂、汽车、发电厂等等放出的一氧化碳和硫化氢等,每天都有人因接触了这些污浊空气而染上呼吸器官或视觉器官的毛病。我们若仍然漠视专家的警告,将来一定会落到无半寸净土可住的地步。

环境污染是指人类直接或间接地向环境排放超过其自净能力的物质或能量,从而使环境的质量降低,对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括:水污染、大气污染、噪声污染、放射性污染等。水污染是指水体因某种物质的介入,而导致其化学、物理、生物或者放射性污染等方面特性的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象。大气污染是指空气中污染物的浓度达到有害程度,以致破坏生态系统和人类正常生存和发展的条件,对人和生物造成危害的现象。噪声污染是指所产生的环境噪声超过国家规定的环境噪声排放标准,并干扰他人正常工作、学习、生活的现象。放射性污染是指由于人类活动造成物料、人体、场所、环境介质表面或者内部出现超过国家标准的放射性物质或者射线。例如,超过国家和地方政府制定的排放污染物的标准,超种类、超量、超浓度排放污染物;未采取防止溢流和渗漏措施而装载运输油类或者有毒货物致使货物落水造成水污染;非法向大气中排放有毒有害物质,造成大气污染事故,等等。

随着科学技术水平的发展和人民生活水平的提高,环境污染也在增加,特别是在发展中国家。环境污染问题越来越成为世界各个国家的共同课题之一。

由于人们对工业高度发达的负面影响预料不够,预防不利,导致了全球性的三大危机:资源短缺、环境污染、生态破坏.人类不断的向环境排放污染物质。但由于大气、水、土壤等的扩散、稀释、氧化还原、生物降解等的作用。污染物质的浓度和毒性会自然降低,这种现象叫做环境自净。如果排放的物质超过了环境的自净能力,环境质量就会发生不良变化,危害人类健康和生存,这就发生了环境污染。

环境污染会降低生物生产量,加剧环境破坏。

环境污染源主要有以下几方面:

1)工厂排出的废烟、废气、废水、废渣和噪音;

2)人们生活中排出的废烟、废气、噪音、赃水、垃圾;

3)交通工具(所有的燃油车辆、轮船、飞机等)排出的废气和噪音;

4)大量使用化肥、杀虫剂、除草剂等化学物质的农田灌溉后流出的水。

5)矿山废水、废渣。

珍惜我们共同的家园,爱护地球的环境,减少对环境的污染,从你我做起!

保护环境善待地球

众所周知,我们只有一个地球。地球是我们的家园。我无法想象,如果地球消失了,人类该怎样生存。

我们的生活不能离开地球,所以,请善待地球。

现在的空气不是很新鲜,天也不是那样湛蓝。这是为什么?因为有很多人乱砍滥伐,还污染河流。我们在森林里看不见小动物玩耍,也看不见小鱼在水里游泳。

如果长时间都是这个景象,世界末日就会来临。

那么,我们怎样才能保护环境呢?让我来给大家一些建议吧。

首先,我们可以植树。树木可以给予我们新鲜的空气,还可以吸收二氧化碳。

其次,我们可以坐公交去上学或上班,少开车。汽车排放的尾气会污染空气,它对我们的身体没有好处,对地球也没有好处。

这就是我的建议。

今天是世界环境日,让我们一起保护环境,善待地球吧!

I went to qingshui river with my father and mother. I was just walking towards the river when I heard a loud crying. I followed the sound of the past, it was a piece of grass. I squatted down and asked, "grass, why are you crying here?" The grass said, "this is a vast prairie, but people are going to build a big house here. My sisters have been pulled out, and I am the only one who has not been pulled out." "Said the grass, and began to cry again.

I stood up, turned and heard: "help me." I walked past, originally is qingshui river to cry. "Why are you crying?" I asked curiously. "Please help me," he said. I saw an aunt throw a pack of garbage into the water. Plastic bags fly apart in the air, wrapped in peel, the leftover soup is scattered into the river. I went over and said, "aunt, its wrong of you to do so." The aunt said angrily: "you care for me? Little thing. You see, everybody is not like this?" I looked across the river and some of the people on the bank had coal dust, some threw waste paper. Some factories are discharging black and black waste water, along the river, into the distance. Then I saw a yellow and yellow thing floating on the river.

God, thats terrible!

Wake up and think of the old water river. In the summer some people play in the river, and some fish swim freely in the water. On the bank of the river, the willows fly, and the bees sing.

From now on, we will save water, protect the environment and protect our homeland. My slogan is "protect the environment from me."

Man and His Environment

Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, mans changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.

今年清明节时,爸爸自己动手做了清明饼,自己采的蒿青,说那才是真正的绿色食品。可谁知饼倒是做得不错,却有种怪味:汽油味。绿色食品不绿色了,反倒成了有毒食品,这是怎么回事呢?原来呀,爸爸的蒿青是在小区门口采的,那儿车辆进进出出的非常多,排出的尾气让人喘不过气儿,那小草一天24小时呆在那儿,能好吗?表面看起来绿油油的挺健康,其实早就中毒不浅了。要知道小草们的家园,我们的生活环境,早已被肮脏的恶劣的变质的空气所包围着,多么可怕呀!21世纪,大气污染,被称为社会一大公害。越是交通发达的国家,由汽车尾气排放的污染物越严重,已成为污染大气的罪魁祸首,激起了社会公愤。据各地监测分析,汽车尾气排放量已占大气污染源85%左右。目前,全世界的汽车拥有量已超过6亿辆,全世界每千人拥有汽车110辆。全世界的汽车拥有量以每年3000万辆的速度增长,预测到全球汽车数量将增到10亿辆。中国的汽车拥有量已超过1400万辆。在车辆不多的情况下,大气的自净能力尚能化解车辆排出的毒素。但眼下已车满为患,交通拥堵成为家常便饭,汽车本应具备的便捷、舒适、高效的特点却被过多的车辆逐步抵消。“汽车灾难”已经形成,汽车尾气更是害人不浅。

空气污染对人们的健康造成越来越大的威胁,而这些有毒气体70%出自汽车尾气。据医学界研究分析,汽车尾气的主要化学成分是二氧化硫、一氧化硫、氮氧化物、铅。它能引起呼吸道感染和哮喘,使肺功能下降,严重的可引起肺气肿。汽车尾气中的铅一般分布于地面上方1米左右的地带,正好是青少年的呼吸带,因而铅污染对青少年危害更重。汽车尾气中的一氧化碳与血液中的血红蛋白结合的速度比氧气快250倍。所以,即使有微量一氧化碳的吸入,也可能给人造成可怕的缺氧性伤害。轻者眩晕、头痛,重者脑细胞将受到永久性损伤;氮氧、氢氧化合物会使易感人群出现刺激反应,患上眼病、喉炎,尾气中氮氢化合物所含苯并芘是致癌物质,它是一种高散度的颗粒,可在空气中悬浮几昼夜,被人体吸入后不能排出,积累到临界浓度便激发形成恶性肿瘤。听听,多么可怕呀,可这一切又都是由人类自己造成的。人类呀,改变你们的生活方式吧!难道你们要做自己生命健康的杀手吗?

现在有许多疾病在危害人类的健康,甚至威胁到人类的生命。人类跨入21世纪,世界发生了多少惊人的变化。在人们为科学技术突飞猛进的发展欣喜之余,又经历了更好的不安甚至灾难。除了对高科技特别是生物科技的发展所带来的恐慌之外,战争和疾病似乎直接将人类带到了地狱之门。

污染对人体的危害,人体在新陈代谢的过程中,随着饮水和食物,把水中的各种元素通过消化道进入人体的各个部分。当水中缺乏某些或某种人体生命过程所必需的元素时,都会影响人体健康。例如,有些地区水中缺碘,长期饮用这种水,就会导致“大脖子病”,就是医学上所称的“地方性甲状腺肿”。当水中含有有害物质时,对人体的危害更大。致癌物质可以通过食用受污染的食物(粮食、蔬菜、鱼肉等),带入人体,还可以通过饮水进入人体。据调查,饮用受污染水的人,患肝癌和胃癌等癌症的发病率,要比饮用清洁水的高出61。5%左右。当污水中含有汞、镉等元素排入河流和湖泊时,水生植物就把汞、镉等元素吸收和富集起来,鱼吃水生植物后,又在其体内进一步富集,人吃了中毒的鱼后,汞、镉等元素在人体内富集,使人体患病而死亡。这样,从水生植物→水生小动物→小鱼→大鱼→人体,形成了一条食物链。人体最后成了汞、镉等元素的“落脚点”。

水污染对水生生物的危害水中生活着各种各样的水生动物和植物。生物与水、生物与生物之间进行着复杂的物质和能量的交换,从数量上保持着一种动态的平衡关系。但在人类活动的影响下,这种平衡遭到了破坏。当人类向水中排放污染物时,一些有益的水生生物会中毒死亡,而一些耐污的水生生物会加剧繁殖,大量消耗溶解在水中的氧气,使有益的水生生物因缺氧被迫迁栖他处,或者死亡。特别是有些有毒元素,既难溶于水又易在生物体内累积,对人类造成极大的伤害。如汞在水中的含量是很低的,但在水生生物体内的含量却很高,在鱼体内的含量又高得出奇。假定水体中汞的浓度为1,水生生物中的底栖生物(指生活在水体底泥中的小生物)体内汞的浓度为700,而鱼体内汞的浓度高达860。由此可见,当水体被污染后,一方面导致生物与水、生物与生物之间的平衡受到破坏,另一方面一些有毒物质不断转移和富集,最后危及人类自身的健康和生命。

水污染对工农业生产的影响工农业生产不仅需要有足够的水量,而且对水质也有一定的要求。否则,对工农业会造成很大的损失,特别是工农业生产过程中使用了被污染了的水后,对人类有着极大的危害。一是使工业设备受到破坏,严重影响产品质量。二是使土壤的化学成分改变,肥力下降,导致农作物减产和严重污染。三是使城市增加生活用水和工业用水的污水处理费用。

清洁的空气是人们赖以生存的必要物质基础,一个成人平均每天要呼吸15立方米空气,人们若呼吸了严重污染的空气,无疑对健康是有害的。因此,研究空气污染的影响,认识清洁空气的价值是一个十分复杂的前沿科研课题。而儿童处于生长发育阶段,是对外界空气污染最敏感人群,研究空气污染对儿童的影响更易获得有价值的结果。基于此,以中国工程院院士、中国环境监测总站总工魏复盛为中方首席科学家的中美科技合作项目一一空气污染对人体呼吸健康的影响研究,在广州、武汉、兰州、重庆等城市和郊区分别选点,对空气中直径2.5微米颗粒物进行调查、监测,取得8196份调查问卷,测试儿童肺功能约15000人次,包括环境监测数据,共获得了约300万个数据,经过统计分析,对空气污染对人体呼吸系统健康(特别是儿童)的影响有了定量化的认识。研究结果证实,对人体健康的影响以空气中细小颗粒物污染最为严重(我国有2/3的城市超标),其次是二氧化硫污染(我国有1/3的城市超标),氮氧化物污染的影响相对较弱。可以说,细小颗粒物(可吸入颗粒物)是人体健康的第一杀手。据专家介绍,颗粒物上附着的有毒重金属、酸性氧化物与土壤相比富集几百倍、几千倍,甚至上万倍,并可在空气中飘浮多达几十天,有害物质随可吸入颗粒物进人体肺部,并有可能透过肺泡进入血液,直接危害人体健康。

近日,这项历时8年的研究成果在京通过了由国家环保总局主持的专家鉴定。专家们认为,这一研究成果对于我们认识清洁空气的重要性、提高公众及领导层的环保意识有着重要意义。研究成果的数据为国家空气环境立法、制定、修订空气质量标准、排放标准及空气污染治理政策提供了科学依据。

家电为了吸引顾客,往往是以提高音箱的分贝为主要手段,各种音乐特别是打击乐发出的声音,会增添人们的焦虑情绪。按照国家规定的标准,公共场所的噪音住宿业小于55分贝、商场(店)、书店小于60分贝、公共交通等候室小于70分贝,但现实的公共场所中,噪音要远大于这个标准。我国对居民生活区的噪音也有相关的规定,住宅区白天的噪音不能超过50分贝(一般说话声音为40~60分贝),室内噪声限值要低于所在区域标准值的10分贝。医学证实,过度的噪音污染,会导致人的耳部不适,出现耳鸣耳痛症状;损害心血管;分散注意力,降低工作效率;造成神经系统功能紊乱。噪音污染的过程其实是一种慢性中毒过程。记得有一幅荣获世界漫画大奖的作品,就是在一间超高分贝的房中,关押着一名犯人,犯人双手抱头面部痛苦,这幅画题名为“极刑”。可见噪音对人的影响。因此,现实生活中,要防止噪音污染,维护健康的生活环境。

让我们来保护环境,治理污染吧!

it was the industrial revolution that gave birth to environmental pollution as we know it today. the emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. chicago and cincinnati were the first two american cities to enact laws ensuring cleaner air in 1881. other cities followed around the country until early in the 20th century, when the short lived office of air pollution was created under the department of the interior. extreme smog events were experienced by the cities of los angeles and donora, pennsylvania in the late 1940s, serving as another public reminder.环境污染现象英语作文二

近年来,大气污染非常严重,雾霾几乎每天都笼罩着天空,不仅给我们的交通安全带来隐患,而且威胁着人们的身心健康。如何改变这种恶劣的环境,净化城市空气已成为当下人们关注的热门话题。

众所周知,造成大气污染的来源诸多,主要来源有三类:其一是生产性污染,这是大气污染的,例如,燃料的燃烧,主要是煤和石油燃烧过程中排放的大量有害物质,如烧煤可排出烟尘和二氧化硫;烧石油可排出二氧化硫和一氧化碳等;另外,生产过程排出的烟尘和废气,以火力发电厂、钢铁厂、石油化工厂、水泥厂等对大气污染最为严重,还有就是农业生产过程中喷洒农药而产生的粉尘和雾滴。 其二是生活性污染,由生活炉灶和采暖锅炉耗用煤炭产生的烟尘、二氧化硫等有害气体。 其三是交通运输性污染,汽车、火车、轮船和飞机等排出的尾气,其中汽车排出有害尾气距呼吸带最近,而能被人直接吸入,其污染物主要是氮氧化物、碳氢化合物、一氧化碳和铅尘等。环境污染是个老生常谈的问题了,之所以越来越严重,一是污染企业的管理者利益驱使金钱作祟,二是政府部门的打击治理的力度不够。这次治理大气污染各级政府重拳出击,人们称赞之余更是拭目以待。治理生产性污染,政府及相关部门要严格治理,对于超标排放的企业坚决取缔,切不可像“治理大型货车超载交了罚款就放行”,而一罚了之,而且要长效监督,杜绝反弹。

诚然,取缔生产性污染企业,作为普通百姓,你我都是“心有余而力不足”。但是,治理大气污染我们也不能完全依赖政府,一些来自生活性的污染,你我都有责任和义务承担。其实,早几年我们就一直在倡导低碳生活,绿色出行,可遗憾的现实生活中有多少人真正付诸行动?。君不见,都晓得机动车排放尾气污染大气,宁可每天抱怨道路堵停车难,也不愿少开一天车;都知道烧烤食品即污染空气又伤害身体.可那一家露天烧烤不是顾客满盈;明知道生产装饰材料会造成大气污染,损害健康,却有多少人在“豪华”的装修;如此这般,是否在做自己害自己“傻事”。如果你我少开一天车,少用一度电或少用一吨水,这些细小的行为看起来微不足道,但是,倘若每个人都能自觉的杜绝铺张浪费,养成勤俭节约的生活习惯,相关企业就会减少产量,就会间接的较少污染。唯有政府的治理和你我的参与,我们的生存环境一定有所改善,天空才会越来越蓝。

There are many diseases that are harmful to human health and even threaten human life. Human into the 21st century, the world has occurred in the number of amazing changes. In the people for the rapid development of science and technology, but also experienced a better anxiety and even disaster. In addition to the panic of the development of high-tech, especially biotechnology, war and disease seem to bring mankind directly to the door of hell.

Water pollution on the human body harm, the body in the process of metabolism, with drinking water and food, the water of various elements through the digestive tract into the various parts of the body. When the lack of water in some of the human life process necessary elements, will affect human health. For example, in some areas of water iodine deficiency, long-term consumption of this water, it will lead to "big neck disease", is the medicine called "endemic goiter." When the water contains harmful substances, the greater harm to the human body. Carcinogenic substances can be consumed by eating contaminated food (food, vegetables, fish, etc.), into the human body, but also through the water into the human body. According to the survey, drinking contaminated water, suffering from liver cancer and gastric cancer and other cancer incidence, than drinking clean water is about 61,5% higher. When the sewage contains mercury, cadmium and other elements into rivers and lakes, the aquatic plants put mercury, cadmium and other elements to absorb and enrich them, fish eat aquatic plants, and in its body to further enrichment, people eat poisonous Fish, mercury, cadmium and other elements in the human body enrichment, so that the human body and death. In this way, from the aquatic plants → aquatic small animals → small fish → big fish → the body, forming a food chain. The body eventually became mercury, cadmium and other elements of the "foothold."

Water pollution hazards to aquatic organisms Water lives in a variety of aquatic animals and plants. Biological and water, between biological and biological complex material and energy exchange, from the number to maintain a dynamic balance. But under the influence of human activities, this balance has been destroyed. Some of the beneficial aquatic organisms are poisoned when humans release pollutants into the water, and some of the stained aquatic organisms will multiply, consume a lot of oxygen dissolved in the water, so that the beneficial aquatic life is forced to relocate due to hypoxia Or death. In particular, some toxic elements, both difficult to dissolve in water and easy accumulation in the body, causing great harm to humans. Such as mercury in the water content is very low, but the content of aquatic organisms is very high, the content in the fish is also surprisingly high. Assuming that the concentration of mercury in the water body is 1, the concentration of mercury in the aquatic organisms is about 700, and the concentration of mercury in the fish is as high as 860. Thus, when the water is contaminated, on the one hand led to biological and water, biological and biological balance between the damage, on the other hand some of the toxic substances continue to transfer and enrichment, and ultimately endanger human health and life.
