环境污染演讲稿 篇1

Let me show you some of them

Population Growth(人口增长)

Increasingly large numbers of people are being added to the world every year. As the number of people increases, more pollution is generated, more habitats are destroyed, and more natural resources are used up. Even if new technological advances were able to cut in half the environmental

impact that each person had, as soon as the world's population size doubled, the earth would be no better off than before.

The Population Division of the United Nations predicts that the 5.63 billion humans alive in 1994 will increase to 6.23 billion in the year 20xx,

8.47 billion in 20xx, and 10.02 billion in 20xx. In fact, because larger

amounts of resources per person are used in the developed nations, each citizen from the developed world has a much greater environmental impact than does a citizen from a developing country.

Global Warming(全球变暖)

This process is referred to as the greenhouse effect.

These greenhouse gases, primarily carbon dioxide, methane, nitrous oxide, insulate the earth's surface, helping to maintain warm temperatures. If the concentration of these gases were higher, more heat would be trapped within the atmosphere, and worldwide temperatures would rise.

Air pollution(空气污染)

A significant portion of industry and transportation is based on the burning of fossil fuels, such as gasoline. As these fuels are burned,

chemicals and particulate matter are released into the atmosphere. These chemicals interact with one another and with ultraviolet radiation in sunlight in various dangerous ways. Smog, usually found in urban areas with large numbers of automobiles, can cause serious health problems.

Water pollution(水污染)

Estimates suggest that nearly 1.5 billion people lack safe drinking water and that at least 5 million deaths per year can be attributed to waterborne diseases. Point sources discharge pollutants at specific locations-from, for example, factories, sewage treatment plants, or oil tankers. Non point

sources- for example ,runoff water containing pesticides and fertilizers from acres of agricultural land -are much more difficult to control. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes.

Species Extinction(物种灭绝)

What is clear is that species are dying out at an unprecedented rate; minimum estimates are at least 4000 species per year, although some scientists believe the number may be as high as 50,000 per year. The

leading cause of extinction is habitat destruction. At the current rate at which the world's rain forests are being cut down, they may completely disappear by the year 20xx.

As habitats are destroyed and species lost, the world is increasingly losing threads from the interconnected fabric of life.

These are 10 kinds of extinct animals in recent decades. They died out because of environmental degradation and human hunting. 桑吉巴尔豹。毛里求斯蚺蛇。 斯皮克斯金刚鹦鹉。金蟾蜍。夏威夷蜜旋木雀。马德拉大白凤蝶。提可巴鳉鱼。比利牛斯山羊。西非黑犀牛。爪哇虎

Chemical Risks(化学成分污染)

Many industrially produced chemicals may cause cancer, birth defects, genetic mutations, or death. Although a growing list of chemicals has been found to pose serious health risks to humans, the vast majority of substances have never been fully tested.

There is only one earth with super living conditions in the universe. It is no doubt that the nature is important to every human being. No nature, no life. I think we can’t prevent environmental degradation, but we can slow down it.

So what can we do to protect our globe? I leave this question to everyone, you can think about it after class.

环境污染演讲稿 篇2

尊敬的老师、同学们:

大家好!

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职责和义务,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景和条件。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,环境对开创人类礼貌和提高发挥着巨大作用。

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供给物质,创造出地球上高度的人类礼貌。可是,人类在开发利用环境资源的同时,也对自我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:很多的生活废弃品,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,并且还会滋生细菌。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。。

此刻像我们柳疃镇、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。人类的活动会使很多的工业、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很多鱼虾死亡,地区农民上海捕鱼,鱼的体内包含很多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一样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,替代了原先垃圾围绕街道,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,从此刻做起: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!

环境污染演讲稿 篇3

看过一部电影,名字是《Erin Brockovich》,中文是《永不妥协》,不是直译,但很能反映这部电影的宗旨,电影根据美国的一个真实案例改编而成。1993年,美国加州Hinkley发生了一起铬污染案件。Pacific Gas&Electric公司使用大型天然气压缩机来压缩天然气,而这些压缩机需要使用冷却塔来冷却。冷却水中含有六价铬,以防止机器生锈。这些水被直接存储于池塘中,严重污染地下水。20xx年的一项调查表明,目前没有污染增加了当地癌症发病率的直接证据。六价铬在当地的水平为3.09ppb至1.19ppb,而美国加利福尼亚州的标准为0.06ppb。在影片中主人公

埃琳·布罗克维奇(朱莉娅·罗伯茨饰)是一位经历了两次离婚并拖着三个孩子的单身母亲,在一次十分无奈的交通事故之后,这个一贫如洗,既无工作,也无前途的可怜妇女几乎到了走投无路的绝境。万般无奈之下,埃琳只得恳求自己的律师埃德.马斯瑞(阿伯特·芬尼饰)雇用她,在律师事务所里打工度日。一天,埃琳在一堆有关资产和债务的文件中很偶然地发现了一些十分可疑的医药单据,这引起了她的困惑和怀疑。在埃德的支持下,埃琳开始展开调查,并很快找到线索,发现了当地社区隐藏着的重大环境污染事件,一处非法排放的有毒污水正在损害居民的健康,是造成一种致命疾病的根源。可怕的是居民们对此并未察觉,甚至起初对埃琳的结论表示怀疑,但是不久他们就被埃琳的执着和责任感打动了,大家在一个目标下紧紧地团结了起来,埃琳用自己的行动赢得了全体居民的信任,成了他们的核心和代言人。邻居乔治(阿伦·埃克哈特饰)在整个事件中是埃琳的一名坚定的支持者,他俩的爱情成了支持埃琳的重要精神支柱。埃琳挨家挨户的做动员工作,终于得到了600多个人的签名支持。埃琳和埃德在一家大型法律事务机构的帮助下,终于使污染事件得到了令人满意的赔偿,创造了美国历史上同类民事案件的赔偿金额之最,达3.33亿美元。埃琳正是用自己的无比坚韧的毅力,克服难以想象的困难,向世人证明了一个“弱女子”的价值,在人生的道路上开辟了一片新的天地。

在影片中当地政府的默许,是导致事情发展严重的重要原因,经济发展对一个地区来说很重要,但当人民的生命安全受到危害时,就应该以人民的生命安全为重。政府以地区的经济发展状况来衡量官员的政绩,导致当地官员将经济发展放在首位,忽视人民的生活安全。在我国,曾有地方官员为了“应对”政策要求的提高绿化面积,用绿漆将光秃秃的山喷遍,远远看去郁郁葱葱,近看则是泛光的绿油漆喷的,这仅仅只是为了“政绩”!喷的漆对环境污染很严重,难以清除成了大山的“绿帽子”,是中国环境污染的一个标识!

我国的环境污染事件众多,其中出现的“癌症村”,于电影中的情形相类似,不同的是中国有很多“癌症村”,政府却无视肇事企业。

“湖南省国土资源规划院基础科研部主任张建新说,他们调查了7万人25年的健康记录后发现,从1965年到20xx年,骨癌、骨痛病人数都呈上升趋势。在重金属污染的重灾区株洲,当地群众的血、尿中镉含量是正常人的2至5倍。内蒙古的河套地区因土地污染地下水质量较差,造成砷中毒、氟中毒等地方病较为严重的情况。河套地区共有近30万人受砷中毒威胁,患病人群超过20xx人。巴彦淖尔盟五原县杨家疙瘩村是砷中毒的重点区,该村病人多,而且死亡人数也多,主要是以癌症为主,大多在壮年时就由于病魔的折磨而过世。”

这些事件和电影中的铬污染相比是有过之而无不及的,我国的环境污染重点是土质和水质环境污染,这两个污染对人们危害也是最大的,以重金属污染最为突出,类似的污染如发生在浙江的“血铅”事件、渤海漏油事件等。我国的环境污染还有空气污染,曾经的伦敦“烟雾”事件,在我国似有再现之势,北京的空气污染最为严重,在北京见到蓝天是很难得的`,北京的空气污染主要来自汽车的尾气排放。广东的空气污染严重到用“一颗红心,两叶黑肺”来形容广州市民的健康状况!导致我国环境污染事件层出不穷的原因很多,在电影中,美国的法律为捍卫人民的生命安全,对污染事件的肇事者有相当严厉的处罚措施,而在我国尚无完整的环境保护法来保护我们的环境,就渤海漏油事件来说,最终康菲被处罚二十万元人民币,这是我国环境保护法中赔款金额的上限!

法律在这方面的缺失和政府在经济发展和环境保护两者间的犹豫不定是造成环境污染屡禁不止的重要原因!从另外一方面看,我国环境污染的原因是多方面的:发达国家的污染环境的企业,大量搬迁到发展中国家。我们一些地方政府,为了发展地方经济,大量引进这类企业,还给予各种优惠政策;国内一些中小企业,不重视保护环境。甚至净化污染物的设备只是摆设,是为了应付检查而设置的,平时随意排污;对于洋垃圾走私的处理不力,以至于有的地方、有的人敢于从国外搞了洋垃圾来赚钱,却污染了自己的环境;城市的盲目扩大、发展,忽视公共交通,不切实际地发展私家车,造成交通堵塞,机动车尾气排放严重污染大气环境;农药、化肥的过量使用;城市垃圾没有好好处理,没有分类收集,造成垃圾污染。这些原因是难以解决的,并且是长期性的,我们需要长期的致力于解决这些问题。环境污染问题从人类进入工业时代就一直存在,当前发达国家已走过了那个为了经济发展而牺牲环境的阶段,他们走的是先污染后治理的路,那是得不偿失的,我们不应学他们,而应污染与治理同步,不能先污染后治理!

就我国当前的状况,我认为我们应立刻采取措施改变当前的污染状况:首先政府应重新或完善有关环境方面的法律,尤其是对污染环境的肇事者应采取严厉的处罚措施,如美国那样,罚款金额没有上限,以此达到以儆效尤的目的。

第二,政府应把经济状况和环境状况结合起来作为衡量官员政绩的标准,以此杜绝地方官员对企业污染的默许。

第三,国家应积极调整经济体制的结构,完成社会形态的转型,减少经济对重污染企业的依靠。

第四,国家应加强对相关企业的监管力度,完善监管体系,在监管时,媒体将充当重要角色,是社会上的电子眼,让违法企业无所藏身;对企业野外作业后的善后处理加强监督,并要求其初步恢复当地生态状况。

第五,对已污染的地区,国家应追究相关企业的责任,并安排专家及相关机构对污染然地区进行治理。

第六,国家应对类如汽车行业生产汽车的标准作出规定,排放量超标的不允许

2上市,我国百分之七十的电力来自火力发电,每天燃烧大量的煤,国家应减少对火力发电的倚赖,提高对新能源的利用率,扩大太阳能、风力的发电规模,适时增建核电站,解决由能源问题带来的环境污染问题。

第七,在城市化发展迅速的今天,国家应加强规划,不能任由城市自然发展,带来严重的交通、环境问题。城市的垃圾处理,不能一味的填埋,这对环境污染是无法估计的,国家应建立封闭式的垃圾焚烧站,对垃圾进行最终处理。

从《永不妥协》这部电影中,我们看到的不仅仅是国家的法律对人民生命安全的保护,和国家对人民所履行的义务和责任——捍卫人民的权利!我看到的还有主人公埃琳·布罗克维奇,作为一个公民,所表现出来的坚强、勇敢、正义!在生活中,我们不仅仅要靠国家捍卫我们的权利,我们自己也要拿起法律的武器来保护我们的生命安全。作为一个大学生,我有责任和义务去保护国家的环境不受破坏和污染,当我们遇到类似于影片中主人公所遇到的问题时,不仅仅是大学生更是每个公民,都应勇敢的于强权恶势作斗争!作为一个大学生,我会努力学习本专业的知识,面对危害人民或国家时,会坚决勇敢的同起作斗争,发扬正义。

维护环境不受污染,是每一个公民的义务和职责,是不可推卸的。保护环境不是一个口号,我们也许一辈子也不会像埃琳·布罗克维奇那样有惊天动地事迹,但我们可以从自己身边的小事做起,类如我们每天都可以少用一个塑料袋,出门随手关灯,节约用水等,通过这些身边的小事将“保护环境”的口号变成现实,变成行动,变成你、我、他之间的默契。

环境污染演讲稿 篇4

we are a normal member of the big family of nature good afternoon everybody. honorable judges, ladies and gentlemen. today,we are gathering here to discuss a very hot issue. how to find harmony in a new age between man and nature? where modern science and technology are concerned i am only a layman i have to say. however, living in this new age , seeing my dear ones suffering from respiratory diseases from time to time, finding the beautiful colors of green and blue are being replaced by that of gray and pale, and realizing that our mother planet is getting more and more unhealthy; i cant help trying to offer my idea and my trivial efforts to look for the answer of the question. as the ancient greek oracle goes: know thyself. i think in answering this above-mentioned question, this precondition is also very important. who are we? this is a question, which should be answered not only by those specialists, but also by every one of human beings. some people may proudly say: we are the masters of nature.

it is true that the idea of man can conquer nature has dominated peoples mind for years, and it is true, man has kept acting like a master and doing whatever things he wants for thousands of years. however, as the consequence of this kind of leadership , now the master seems to be confronted with problems that are far beyond his control. facts are really very ample. the green house effect leaves islands and cities along the coast, such as this oriental pearl-shanghai, in danger of the disaster of being drowned; the holes of the ozone layer make the earth less suitable to live for some creatures including human beings; the phenomena of el nino and la nina leave the land with serious flood and drought, and the diseases, caused by pollution, are increasing at an incredible speed... seeing all these facts, can we still ignore the counterattack of nature? we are not the masters of nature. facing all the disasters made by ourselves, we, mankind as a whole should realize that we are just a normal member of the big family of nature. any mistreatment towards nature will meet only with the revenge from her. by saying so, i do not mean we should give a sudden stop to any development. because that will result in a threat to the existence of human society. i mean we should treat nature

equally, leaving the chance of existence and development to nature as we are obtaining the same thing, and thus we will get the situation of win-win. i am very pleased to find that now more and more people, from every corner of the planet, have come to realize that harmony with nature is the only way to universal and continuous progress and prosperity. and i think that is why we come here from all over the country to discuss this topic today. i want to end my speech by quoting from mr. nixon. our destiny offers, not the cup of despair, but the chalice of opportunity. the future is not ours to see of course. however, by seizing firmly the opportunities, by knowing clearly about ourselves, we, human beings, can doubtlessly achieve the real harmony with nature! thank you very much.

环境污染演讲稿 篇5

尊敬的老师,亲爱的同学们:

大家好!我是六(2)班的郑倩琦。

我演讲的题目是《保护环境,从我做起》这些年来。我们国家受到了严重的环境污染,特大沙尘暴在我国一次又一次发生,它将会掩埋草地、吞毁家园,严重地影响了人民的生活,使我们难以生存。绿色的草地将会变成沙漠,大树将会永远卧倒在地,而我们也不会快乐生活:幸福没有了,亲人没有了,连我们赖以生存的地球也会在茫茫宇宙中粉碎,就像玻璃摔在地上一样。然而这不仅是沙尘暴带来的灾难。

现在,连南极也遭到了污染破坏。因此,地球上失去了最后一块净土。泰山原来是被人们观赏的好地方,居然也成了保护区。

而我们,难道就只能袖手旁观吗,难道我们只能看着这美丽而脆弱的地球永远消失在人间吗?从此,我们能看到风吹草地见牛羊,白云下面马儿跑的那种景象吗?我们能为地球妈妈做些什么呢! 那就从身边的小事做起吧。当你和家人出去旅游时,不但自己不乱扔果皮,包装纸,而且发现垃圾还能主动拣起来投进垃圾箱里,那你就是一个保护环境的好少年;在学校里,看见自来水龙头没关紧,你能上前动手把它拧紧;看到光线充足,能主动把灯关掉,那你就是一名节约资源的好学生……只要大家都做一个爱护环境的有心人,就能为我们的`家园尽一份力,添一片绿,将来就能把地球建成一个更加美好和谐的新家园。

保护环境,从我做起,从身边的小事做起,让我们的家园在希望中崛起吧。

谢谢大家,我的演讲结束了。
