Environmental Protection

环境保护

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.

现如今我们的自然环境已经成为一个重要问题。世界人口增长如此之快以至于世界已经变得过于拥挤。我们在消耗自然资源的同时危险化学物品污染着我们生存的环境。如果我们继续这样下去,地球上的生物将不能生存。

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.

相关人士在环境保护方面做出了一些进展。许多国家的政府已经建立法律来保护大气,森林和海洋资源以停止环境污染。

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(保存) our natural resources and recycle(再循环) our products. We are sure that we can have a better and cleaner place in the future.

同时更应该采取措施来解决环境问题。应该进一步教育人们认识到问题的重要性,应用现代的生产控制方法来节约我们的自然资源和实现产品的再循环。我们相信在将来我们会拥有一个更好的更干净的生存之地。

With the continuous development of science and technology, the increasing number of cars, emissions of emissions has caused serious pollution, perhaps, a few years later generations, hundreds of years after everyone, perhaps because of air pollution and death. Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?

According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?

How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.

Animals have warned against humans;

Bacteria have warned against humans;

Every innocent life warned us.

"Human, do not harm yourself, do not kill us again!"

随着科技的不断发展,汽车的不断增多,排放的废气已经造成了严重的污染,或许,几年后的子孙后代、几百年后的大家,或许会因为大气污染而死亡。现在,地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡,如果这样延续下去,地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计,每一年,每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡,大家或许会觉得很夸张,但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物,每一只动物,每一只有益的细菌,因为,很有可能,在几万年后的今天,他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

“人类,不要再害你自己,不要再害死我们了吧!”

尊敬的卫生局局长:

您好。我是载德小学六二班的一名小学生。近期,我发现在雅居乐小区的环境污染情况严重,为此,我向你提出建议。

在雅居乐后面一条小河边,原本是一条清澈见底,小鱼、小虾自由自在玩耍的地方。可是近期来,住在雅居乐的居民和一些工厂里的员工,将自己在家每天生产的垃圾全部扔进河水里,给河水带来了严重的污染。每天中午,水面上都漂浮着一个个塑料袋、塑料瓶、人们吃过的方便面盒子……然而,到了早晨,人们一打开窗门,想呼吸新鲜空气时,却闻到了河水上垃圾刺鼻的味道,而这就是人们最难接受的事情。最可恶的就是,那些工厂在晚上的时候,偷偷排除那些有毒的废水:白的、红的、蓝色加绿色的、浑浊在一起的……让人看着就恶心。

所以,我恳请卫生局局长,派人治理周边的环境,还给大家带来的清新空气。我建议让卫生局的人每周都随时抽查工厂,检查他们是否造成了环境污染,发现了,就要他们承受一些合理的处罚。还要经常派人捞垃圾;看到有人乱扔垃圾,也要采取措施。

我希望以后的环境污染能够得到改善,能够让我们在一开窗时,就能闻到新鲜的空气;我们再去看小河时,小鱼、小虾能够在那里安居乐业。

篇10:环境污染的原因

一:环境污染的根源

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

二:环境污染

就最近这几年来看,随着各地区的经济迅猛发展,环境污染问题也越来越严重,保护环境,维持生态平衡也成为了我们每个公民应尽的责任和义务,也是为了社会更好发展的一项重要举措!

何为环境?从哲学的角度来看,所谓环境,主要指我们所研究的主体周围的一切情况和条件。对于人来说,环境是指人生活于其中,并能影响人的一切外部条件的综合。人的生活离不开好的环境,在人类几百万年的历史进程中,环境对开创人类文明和进步发挥着巨大作用。

大气资源、水资源、土地资源等等,都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质,创造出地球上高度的人类文明。但是,人类在开发利用环境资源的同时,也对自己的生存环境产生了一系列环境问题。

在我们身边就有很多污染环境的污染物,例如说:大量的生活废弃品,塑料袋(也称白色垃圾),一次性木筷,一次性饭盒,果皮纸屑。污染物对环境来说,毫无疑问,肯定有很大的危害,例如动物的腐烂的尸体会影响环境卫生,而且还会滋生细菌。饭店、餐馆认为很卫生的一次性木筷,使用后随便一扔,影响了市容,破坏了环境。。

现在像我们柳疃镇、青乡乡,最近电网部门纷纷撤除喷水机器的使用。喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。人类的活动会使大量的工业、农业和生活废弃物排入水中,使水受到污染。又例如说,我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡,地区农民上海捕鱼,鱼的体内含有大量化学物质对人们的身体健康造成了危害。据资料统计,目前,全世界每年约有4200多亿立方米的污水排入江河湖海,污染了5.5万亿立方米的淡水,这相当于全球径流总量的14%以上。1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义,即水体因某种物质的介入,而导致其化学、物理、生物或者放射性等方面特征的改变,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称为水污染。水的污染有两类:一类是自然污染;另一类是人为污染。当前对水体危害较大的是人为污染。水污染可根据污染杂质的不同而主要分为化学性污染、物理性污染和生物性污染三大类。

最近,我发现政府部门、昌邑环卫局开始大力整治环境,沿街排查污染源,青乡街也定点安置了便民垃圾桶,替代了原来垃圾围绕街道,臭气熏天的状况。各个村庄开始整治村内环境的污染源,使街道、村庄焕然一新!而这不是主要的,更重要的是我们每个人自觉保护环境,保护我们赖以生存的家园,为了我们更为了我们的后代,树立好榜样,奠基好基础,让我们的家园更加美丽、更加丰富多彩!

所以呢!环境与我们的生活密切相关,保护环境卫生从我做起,从现在做起:不随地吐痰;不乱扔垃圾;废弃电池和塑料袋要处理好;多植树造林,不践踏草坪;不污染水源。保护环境,我们有责!看你的行动喽!

小建议:家庭生活中的塑料瓶可以做成装饰品,可回收物品可以卖出,换来金钱买实用的东西岂不很好?一次性木筷消毒清洗一下可以做成装饰品,你也能开小店赚大钱了!化废物为贵宝,让自己的心情更舒畅,让自己的心灵更纯洁,让自己的家庭更温馨!

三:环境污染

在二十一世纪的今天,人类赖以生存的地球环境越来越恶劣,灾难频发,旱灾、洪涝灾害、土地沙漠化、地震、全球气温上升、海啸等等过去,以我所受到的信息宣传,简单以为环境污染只是浓烟滚滚,或者水面上漂浮着垃圾、发出恶臭,蚊虫成堆、尘土飞扬等等。但是,今年从网络、报纸、广播、电视、人们的关注里,我似乎明白;现实的情况要糟得多。西南五省大旱,就是我们自己想都没有想到的原因,专家分析:因为在过去10几年中,西南从新西兰大量引进桉树速生林,为了求短期的经济利益,毫无限制的大面积种植,以用来工业造纸,从而导致物种生态环境失衡,形成地下水严重缺失。俗话说,十年树木,百年树人,可这种桉树两三年就成材,是一种巨大的抽水机和抽肥机,不断侵蚀着其他植物物种的生存空间,而当地人却沉浸在多种树就可以保护环境的僵化错误的指导思想中,不断的在往恶性循环上发展,正是这个想到想不到的原因最终导致西南几百年的大旱灾。在报纸上,我看到温总理在一片干涸开裂的耕地上,捧着一颗枯死的禾苗,只说了一句话:“痛定思痛!”云南拥有大片的原始森林,风景名胜众多,地理环境独特,自古以来就是一个山清水秀,气候宜人的好地方,可是为了种植这种桉树,大量砍伐原始森林,想象这些经过几十年甚至数百年才形成的树木,仅仅是为了去满足最快速度的造纸而被破坏,真是让人可惜,并且痛心。据说旱灾的另一个原因,就是所有的大江小河都修起了水电站。对这一点我有自己的感受,早两年湘江的水面多么宽广,可是上游修了一个水电站后,下游的水明显减少,甚至连河床都经常露出来,同时影响到了城市自来水的引水工程,我都有这些感受,那些江河里小鱼虾们感受就应该更深了。前些天报纸上又爆出地沟油事件,报纸上说地沟油是别人吃完的饭菜倒进垃圾桶后,一些黑心商人把这些进行简单的提炼加工后,不但闻不出异味,加入香精后吃起来还挺香,但是对人体危害很大,我现在都不敢随便在外面吃东西了。环境污染的问题日益严重,影响到了我们生活的方方面面,对此我感到非常的忧虑。

四:河道为什么会污染

在我们学校旁边,有一条小河,听长辈们说,原来这里的河水清澈见底,河里鱼虾成群,夏天人们喜欢在水里游泳,还直接取水饮用呢!可如今,河水不但变得混浊,有时还有臭味呢!

为什么河水会发生翻天覆地的变化呢?经过我们全班同学的观察分析,河水污染有许多原因 。首先,人们不重视环保,乱倒垃圾。如有一次,我去张微家去玩,吃了一根香蕉,问她的妈妈:“阿姨,香蕉皮扔哪里?”只见她从我手中拿过香蕉皮,又随手用力一扔,扔进了小河,说:“这就是我们家的垃圾桶。”甚至有人把死猫死狗也扔进去了,这时,如果你从旁边经过,一阵阵臭味就会扑鼻而来。我真是不明白,人们为什么不多走几步把垃圾扔到垃圾箱里让垃圾车运走呢?。其次,人们家里的化粪池的排污口就直接通向小河。特别是我们学校,大小便没有经过处理就流进了小河,让人看了真是恶心。河水不变臭才怪呢!还有人们给庄稼喷了农药后,就在河里洗药筒等等。由于各种原因使河水变得越来越脏,甚至发臭,更不用说饮用,就连小鱼也快要无家可归了。

我想向人们呼吁:“水是生命的源泉,没有水就没有生命,就没有我们这个美丽可爱的家园,所以请你们不要再伤害小河了,难道你们就没有看见小河在哭泣吗?”

I have had a dream, in the dream I dreamed that the qingshui river became very terrible.

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."

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.

写作的时候少不了需要事例,欢迎阅读环境污染事例作文哦!

在一些国家,资本家或生产单位的经济人为了追求高额利润,任意向自然界排放各种有害物质,严重污染环境,特别是大气和水源的污染,造成社会公害,引起许多疾病,使广大人民的健康和生命受到严重威胁。

对水源的污染有多种,其中“水俣病”就是举世闻名的日本公害之一。

“水俣病”于1953年首先在日本九州熊本县水俣镇发生,当时由于病因不明,故称之为水俣病。

1950年在水俣湾附近渔村中,发现一些猫步态不稳,抽筋麻痹,最后跳入水中溺死,当地人谓之“自杀猫”。

1953年水俣镇发现一个生怪病的人,开始只是口齿不清,步态不稳,面部痴呆,近而耳聋眼瞎,全身麻木,最后神经失常,一会酣睡,一会兴奋异常,身体弯弓,高叫而死。

1956年在这个地区又发现五十多人患有同样症状的病。

经过对病的调查和研究,在1962年才确定水俣病的发生是由于汞的环境污染,特别是常期食用被污染的鱼和贝类引起的甲基汞慢性中毒。

这是从水俣镇的工厂排放的氯化甲基汞污染海域,使鱼和贝类中毒造成的。

继水俣镇之后1963年,日本新泻县又有大批自杀猫、自杀狗出现。

1973年在有明海南部沿岸的有明町等地又发生了水俣病。

据报导这三次发病人数共计900多人,实际上在日本受害人数远远超过这个数字,仅水俣镇受害居民已有一万人左右。

汞俗称水银,它广泛应用于许多工业部门。

汞及其化合物都是有害物质,尤其是汞的烷基化合物的毒性更大。

汞及其化合物可以通过呼吸或消化系统进入人体污染环境的事例作文。

无机汞进入人身体后,含汞浓度最高的是肾脏和肝脏。

有机汞在人脑中蓄积最为显著,其次是肝和肾

汞中毒后的临床症状即如“水俣病”症状。

造成水污染的工业公害除汞外,还有酚、氰类、铬、砷及某些重金属盐等物质。

这些物质从工厂及科研单位排放出来,造成了严重的水污染。

从而对人类造成的危害在国内外都时有发生。

因此在发展国民经济,加快四个现代化的进程中,一定要注意保护人类赖以生存的环境,防止污染,使人类在优美、舒适的环境中生存发展。
