环境污染演讲稿2

  Many people are active in fighting against unfair treatment to colored people,women, animals and so on.Right now I am talking about fighting for respect to our environment。 Though the environment doesn't have a mouth to deprecate what humans have done to her, she retaliates through action.In the early years the Chinese cut down large quantities of trees,at the source of the yellow river, which led to the disappearance of big forests and terrible floods.

  As a result,the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants。 Another example was in several developed countries.Because many chemical factories discharged poisonous gas without filtering it,cities were covered with so much poisonous gas that people were killed by the air they breathed in.What horrible scene! What we are suffering is only a small part of what the nature once suffered.If we don’t take action to show respect to the environment,we will have to face an increasingly awful situation。 Measures should be taken to protect the environment on which we are relying.

  First governments should forbid destroying vegetation,rivers and lakes,oceans,as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment.Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.Only by changing the way we treat the environment can we get along well with it.Only by saving the environment can we save ourselves.

  大气污染的危害主要有以下几个方面:

  1.对人体健康的危害

  大气污染:物对人体的危害是多方面的,大气中污染物的浓度很高时,会造成急性污染中毒,或使病状恶化,甚至在几天内夺去几千人的生而患病。

  2.环境污染与癌症

  大量研究资料表明,环境污染是导致癌症发生的一个极其重要的原因,依靠全社会的力量,采取综合措施、有效地治理环境污染,是癌症综合预防措施的重要组成部分。

  3.对植物的危害

  大气污染物,尤其是二氧化硫、氟化物等对植物的危害是十分严重的。当污染物浓度很高时,会对植物产生急性危害,使植物叶表面产生伤斑,或者直接使叶枯萎脱落造成植物产量下降,品质变坏。

  4.天气气候影响:

  大气污染物对天气和气候的影响是十分显著的,

  ①减少到达地面的太阳辐射量:据观测统计,在大工业城市烟雾不散的日子里,太阳光直接照射到地面的量比没有烟雾的日子减少近40%。大气污染严重的城市,天天如此,就会导致人和动植物因缺乏阳光而生长发育不好。

  ②增加大气降水量:从大工业城市排出来的微粒,其中有很多具有水气凝结核的作用。因此,当大气中有其他一些降水条件与之配合的时候,就会出现降水天气。

  ③下酸雨:有时候,从天空落下的雨水中含有硫酸。这种酸雨是大气中的污染物二氧化硫经过氧化形成硫酸,随自然界的降水下落形成的。硫酸雨能使大片森林和农作物毁坏,严重破坏自然环境。

  ④增高大气温度:在大工业城市上空,由于有大量废热排放到空中,因此,近地面空气的温度比四周郊区要高一些。这种现象在气象学中称做"热岛效应"。

  ⑤对全球气候的'影响:经过研究,人们认为在有可能引起气候变化的各种大气污染物质中,二氧化碳具有重大的作用。从地球上无数烟囱和其他种种废气管道排放到大气中的大量二氧化碳,约有50%留在大气里。二氧化碳能吸收来自地面的长波辐射,使近地面层空气温度增高,这叫做"温室效应"。经粗略估算,如果大气中二氧化碳含量增加25%,近地面气温可以增加0.5~2℃。如果增加100%,近地面温度可以增高1.5~6℃。有的专家认为,大气中的二氧化碳含量照现在的速度增加下去,若干年后会使得南北极的冰熔化,导致全球的气候异常。

环境污染演讲稿4

  In China, I think the most serious environmental problem is the air pollution, water pollution, land desertification, soil erosion. I think the earth's temperature rises

  Is the most serious. After evaporation temperatures, more intense, so will cause drought. Temperatures, glacier melt after,

  Sea level will rise, a direct impact on people's life.

  I think, water can be recycled. Because water is limited resources, is not renewable, water recycling

  Is a waste, and energy saving.

  In everyday life, there are many waste of resources. For example, many the use of disposable chopsticks, disposable plastic bags,

  Waste water etc.

  For our common homeland, I think everyone is responsible for our survival environment to do something

  Useful things. Above all, want to improve people's massive propaganda, enlightenment and understanding, strengthen the consciousness of environmental protection.

  Next, want to undertake recycling of forest trees, reduce the deforestation. Strengthen the white pollution treatment, use less plastic products.

  Finally, to make improvement. Make clean city. A more orderly DaiZhuangHua garbage. This can not only reduce

  The sanitation workers less workload, still can better play recycling, reduce pollution and save resources.

  Buy vegetables, use less plastic bags, try to use bamboo basket. Eating out as far as possible need not disposable lunch boxes

  How to Be Popular

  Most people would like to be popular with others, but not everyone can achieve this goal. What is the secret to popularity? In fact, it is very simple. The first step is to improve our appearance. We should always make sure that we stay in good shape and dress well. When we are healthy and well-groomed, we will not only look better but also feel better. In addition, we should smile and appear friendly. After all, our facial expression is an important part of our appearance. If we can do this, people will be attracted to our good looks and impressed by our confidence.

  Another important step is developing more consideration for others. We should always put others first and place their interests before our own. It's also important to be good listeners; in this way people will feel comfortable enough to confide in us. However, no matter what we do, we must not gossip. Above all, we must remember to be ourselves, not phonies. Only by being sincere and respectful of others can we earn their respect. If we can do all of the above, I am sure popularity will come our way.

  未来10年,33%家庭将为恢复健康倾家荡产!亲们,为健康,为未来开始未雨绸缪吧!

  未来十年,中国将出现癌症井喷,中国33%的家庭将耗尽所有的积蓄,到底是谁偷走了我们的健康?

  我们把所有的空闲时间用来休息,却总是感觉疲劳。

  医院的楼盖的一年比一年高,可是病人却越来越住不下了,医院的设备一年比一年先进了,可是很多病却查不出来了,药品的种类一年比一年全了,可是吃了却不管用了……第一:水污染第二:空气污染

  我们的空气污染远远超出我们所知道的,就不说臭氧层,就说PM2.5,很多的城市都不合格!世界上污染最严重的城市有一半以上在中国。今年一月份的北京有一半时间都是重度污染!中国患肺癌死亡的'人数已经上升到所有癌症的首位,这和抽一手烟、二手烟、汽车尾气、室内装修...

  第三:土地污染

  我们的土地重金属污染极其严重!多年农药和化肥的使用,使土地的肥力下降,农药残留还严重威胁到我们的健康,首先遭殃的就是我们的肝脏,肝脏具备解毒功能,最先被危害!

  更重要的是我们吃的东西存在很多的问题!

  ①人体每天需要摄入5-13份的蔬菜和水果。目前蔬菜冷藏技术发展,让我们随时都可以吃到鲜菜,大棚蔬菜,反季节蔬菜等多不胜数,农药,除草剂,化肥等等数不胜数

  ②激素滥用:以前猪是10个月出栏,现在5个月就出栏了;鸡以前

  3、5个月长成,现在通过激素和抗生素的喂养,只需40天就可长到5斤多重,激素催熟成了不辩的实事。 ③抗生素的滥用:也使我们的营养素流失严重!抗生素危害到我们的肝、肾,而维生素、蛋白质等

  如果你不想在10年后,用辛苦打拼换来的财富,拯救自己的健康。请现在就行动起来,学会保护环境,减少污染;开始低碳生活,绿色出行;学会运动养生,健康饮食;关注“生命之源”,拥抱健康生活。

环境污染演讲稿6

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7

  环境污染:大气污染、土壤污染、水体污染

  一、污染源

  来源

  大气污染源就是大气污染物的来源,主要有以下几个:

  (1)工业:工业生产是大气污染的一个重要来源。工业生产排放到大气中的污染物种类繁多,有烟尘、硫的氧化物、氮的氧化物、有机化合物、卤化物、碳化合物等。其中有的是烟尘,有的是气体。

  (2)生活炉灶与采暖锅炉:城市中大量民用生活炉灶和采暖锅炉需要消耗大量煤炭,煤炭在燃烧过程中要释放大量的灰尘、二氧化硫、一氧化碳、等有害物质污染大气。特别是在冬季采暖时,往往使污染地区烟雾弥漫,呛得人咳嗽,这也是一种不容忽视的污染源。

  (3)交通运输:汽车、火车、飞机、轮船是当代的主要运输工具,它们烧煤或石油产生的废气也是重要的污染物。特别是城市中的汽车,量大而集中,尾气所排放的污染物能直接侵袭人的呼吸器官,对城市的空气污染很严重,成为大城市空气的主要污染源之一。汽车排放的废气主要有一氧化碳、二氧化硫、氮氧化物和碳氢化合物等,前三种物质危害性很大。

  (4)森林火灾产生的烟雾。

  二、危害

  大气污染的危害主要有以下几个方面

  危害人体

  大气污染物对人体的危害是多方面的,主要表现是呼吸道疾病与生理机能障碍,以及眼鼻等粘膜组织受到刺激而患病。

  大气中污染物的浓度很高时,会造成急性污染中毒,或使病状恶化,甚至在几天内夺去几千人的生命。其实,即使大气中污染物浓度不高,但人体成年累月呼吸这种污染了的空气,也会引起慢性支气管炎、支气管哮喘、肺气肿及肺癌等疾病。

  对植物的危害

  大气污染物,尤其是二氧化硫、氟化物等对植物的危害是十[2]分严重的。当污染物浓度很高时,会对植物产生急性危害,使植物叶表面产生伤斑,或者直接使叶枯萎脱落;当污染物浓度不高时,会对植物产生慢性危害,使植物叶片褪绿,或者表面上看不见什么危害症状,但植物的生理机能已受到了影响,造成植物产量下降,品质变坏。

  影响气候

  大气污染物对天气和气候的影响是十分显著的,可以从以下几个方面加以说明:

  ①减少到达地面的'太阳辐射量:从工厂、发电站、汽车、家庭取暖设备向大气中排放的大量烟尘微粒,使空

  气变得非常浑浊,遮挡了阳光,使得到达地面的太阳辐射量减少。据观测统计,在大工业城市烟雾不散的日子里,太阳光直接照射到地面的量比没有烟雾的日子减少近40%。大气污染严重的城市,天天如此,就会导致人和动植物因缺乏阳光而生长发育不好。

  ②增加大气降水量:从大工业城市排出来的微粒,其中有很多具有水气凝结核的作用。因此,当大气中有其他一些降水条件与之配合的时候,就会出现降水天气。在大工业城市的下风地区,降水量更多[1]。

  ③下酸雨:有时候,从天空落下的雨水中含有硫酸。这种酸雨是大气中的污染物二氧化硫经过氧化形成硫酸,随自然界的降水下落形成的。硫酸雨能使大片森林和农作物毁坏,能使纸品、纺织品、皮革制品等腐蚀破碎,能使金属的防锈涂料变质而降低保护作用,还会腐蚀污染建筑物。

  在大工业城市上空,由于有大量废热排放到空中,因此,近地面空气的温度比四周郊区要高一些。这种现象在气象学中称作"热岛效应"。

  经过研究,人们认为在有可能引起气候变化的各种大气污染物质中,二氧化碳具有重大的作用。从地球上无数烟囱和其他种种废气管道排放到大气中的大量二氧化碳,约有50%留在大气里。二氧化碳能吸收来自地面的长波辐射,使近地面层空气温度增高,这叫做"温室效应"。经粗略估算,如果大气中二氧化碳含量增加25%,近地面气温可以增加0.5~2℃。如果增加100%,近地面温度可以增高1.5~6℃。有的专家认为,大气中的二氧化碳含量照20xx年以后的速度增加下去,会使得南北极的冰熔化加速,导致全球的气候异常。

  三、防治

  防治空气污染是一个庞大的系统工程,需要个人、集体、国家、乃至全球各国的共同努力,可考虑采取以下几方面措施

  减少污染排放量

  改革能源结构,多采用无污染能源(如太阳能、风能、水力发电)

  和低污染能源(如天然气),对燃料进行预处理(如烧煤前先进行脱硫),改进燃烧技术等均可减少排污量。另外,在污染物未进入大气之前,使用除尘消烟技术、冷凝技术、液体吸收技术、回收处理技术等消除废气中的部分污染物,可减少进入大气的污染物数量。植物净化法,我国利用植物源消毒灭菌已有3000多年的历史。

  自净能力

  气象条件不同,大气对污染物的容量便不同,排入同样数量的污染物,造成的污染物浓度便不同。对于风力大、通风好、湍流盛、对流强的地区和时段,大气扩散稀释能力强,可接受较多厂矿企业活动。逆温的地区和时段,大气扩散稀释能力弱,便不能接受较多的污染物,否则会造成严重大气污染。因此应对不同地区、不同时段进行排放量的有效控制。工业区

  厂址选择、烟囱设计、城区与工业区规划等要合理,不要排放大气过度集中,不要造成重复迭加污染,形成局部地区严重污染事件发生。

  绿化造林

  茂密的林丛能降低风速,使空气中携带的大粒灰尘下降。树叶表面粗糙不平,有的有绒毛,有的能分泌粘液和油脂,因此能吸附大量飘尘。蒙尘的叶子经雨水冲洗后,能继续吸附飘尘。如此往复拦阻和吸附尘埃,能使空气得到净化。

  改变燃料构成

  实行由煤向燃气的转换。同时,加紧研究和开辟其他新型的能源,如太阳能、氢燃料、地热等。这样也可以大大减轻烟尘的污染。

  植物原液纳米提取净化

  在亚洲发达国家,新加坡,日本,香港,台湾,已经率先使用该技术进行城市、家居,汽车内空气的净化处理。随着港澳台交流沟通的日益频繁,此技术也随之进入中国大陆。AQ空气净化喷雾水综合了植物去除法的和化学去除法的优点而摒弃了它们的不足,首先较化学去除甲醛法植物安全无二次污染,比之化学去除法,由于它是植物提取的,所以安全性高。B这种植物自身带有一定气味留在空气中,一旦完成氧化进程气味会迅速消失。而不像其它植

  物精油弥留很久。C有效成份萜类小分子同时将醛、苯、醚类有害污染物质包围、氧化、分解、清除或无害化,并增加了空气中的有效氧含量,对人体的呼吸系统功能有明显提高。能够快速分解、氧化臭味、异味分子,杀灭致腐、致臭微生物,释放植物源清香因子,既消除了臭味源,又增加了空气清新效果。

  从自己做起

  不要乱扔废弃物;出行尽量乘坐公交车、地铁,减少私家车使用;多参加植树等绿化活动;私家车安装尾气处理装置,使用润滑油使燃油充分燃烧,减少有害气体排放。

  减少雾霾天气外出(根据相关解释,Ozone为臭氧,而PM2.5指的是直径为2.5微米以下的细颗悬浮粒物,也叫可入肺颗粒物,这种悬浮颗粒是空气中的“健康杀手”。对呼吸系统、心脏及血液系统等造成广泛的损伤)。

  出门戴口罩(口罩材质、使用寿命、技术水平等因素是界定口罩质量高低的标准,消费者如无特殊需要,不必抢购标有各种功效的“概念口罩”)。

  注意清洁(深层清洁毛孔的灰尘、细菌,保护人体防护的第一道防线—皮肤)。

  补充营养,增强抵抗力。

环境污染演讲稿8

  环境(Environment)

  Like all other living beings, humans have clearly changed their environment, but they have done so generally on a grander scale than have other species. Some of these changes-such as the destruction of the world's tropical rain forests to create grazing land for cattle or the drying up of almost three-quarters of the Aral Sea, once the world's fourth-largest freshwater lake, for irrigation purposes-have led to altered climate patterns, which in turn have changed the distribution of species of

  animals and plants.

  Scientists are working to understand the long-term

  consequences that human actions have on ecosystems, while environmentalists-professionals in various fields, as well as

  concerned citizens in the United States and other countries-are struggling to lessen the impact of human activity on the natural world.

  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.

  Depletion of the ozone layer(臭氧层变薄)

  The ozone layer, a thin band in the stratosphere (a layer in the upper atmosphere), serves to shield the earth from the sun's harmful ultraviolet rays

  In the 1970s, scientists discovered that the layer was being

  attacked by chlorofluorocarbons (CFCs), chemicals used in refrigeration, air-conditioning systems, cleaning solvents, and aerosol sprays.

  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.

  Nonpoint sources-runoff water containing pesticides and fertilizers from acres of agricultural land, for example-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, particularly of the world's richest

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

  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.

  Environmental Racism(环境歧视)

环境污染演讲稿9

  大家好!

  绿色是时尚的代名词,绿色是树之名,绿色是小溪的欢歌,绿色是花儿的枝叶,绿色象征着生气。

  树,人类的'朋友,它奉献氧气吸入二氧化碳,为人类净化空气,抵挡沙化、风尘、赤潮。但是,人们怎么报答它的?滥砍滥伐。知道吗?中国森林面积只有15.8亿公顷,森林掩盖率也只有16.5%。

  地球森林掩盖率已经下降了20%—30%,假如再不加以克制,人类将失去这个朋友,那时,人们醒悟会不会太迟了?

  人类,地球的“破坏者”,动物,人类的伙伴,为什么动物濒临灭亡?由于偷猎。树木,动物的家园,失去家园,动物何处容身?湿地,在中国已经遭到破坏,盲目地围垦、掠夺开发、污染加剧、过度利用等因素,全国三分之一的自然湿地面临被转变、丢失的危急。导致生态环境失去平衡。工厂大量地排出废气、废水、废物,使环境质量恶化。地球资源原来可以再生,可人类却滥用化学品,致使原来再生的资源不能再生。

  关怀地球就是关怀我们的家园,爱护资源就是爱护我们生存进展的根底。地球只有一个,她是人类赖以生存的漂亮家园。

  我们再也不能迟疑了。全人类应当行动起来,爱护我们的家园。

  作为一名小学生,我们怎样才能爱护我们的家园呢?我认为,要从小事做起,从我做起。首先,爱护我们四周的环境,讲究卫生,不乱扔废弃物,不乱倒垃圾,爱惜花草树木,保持校园环境洁净干净。

  其次,爱护我们四周的环境,建立“绿色环保”少年岗,植树造林,掌握土地沙漠化,扩大绿地面积。

  善待地球,爱护地球,爱护资源环境,就是爱护我们自己,同时也为我们子孙后代留下美妙的家园。只有每个人都齐心协力,齐抓共管,才能使明天的家园,变得更加漂亮。

  感谢大家!

环境污染演讲稿10

敬爱的老师,亲爱的同学:

  在二十一世纪的今日,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。可是,今年从网络、报纸、广播、电视、人们的关注里,我似乎明白;现实的情景要糟得多。专家分析:因为在过去10几年中,西南从新西兰很多引进桉树速生林,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,构成地下水严重缺失。

  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能够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,很多砍伐原始森林,想象这些经过几十年甚至数百年才构成的树木,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。对这一点我有自我的感受,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当更深了。

  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,可是对人体危害很大,我此刻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,对此我感到十分的忧虑。

环境污染演讲稿11

  同学们,你见过树吗?不,你见过的是街道两旁或公园里的树,单调、乏味、黑不溜秋。你见到水吗?不,你见过的是人工湖的水,浑浊、发臭、游人洗过脚的。你见过鸟吗?不,那是笼中之鸟,呆呆的、只会要吃的。 近年来,随着经济的发展、社会的进步,我国的环境也随之变化,大自然受到严重的破坏,如果我们还不行动起来,保护环境

  ,那么在未来的某一天,我们顶会濒临动植物灭绝的死亡线上。

  由于我国人口素质还不够高,对生态系统缺乏认识、不了解自然规律,近年来,我国的自然环境和生态平衡已经遭到严重的破坏。比如为取暖、做饭、盖房子大量破坏森林,进而造成水土流失、河道淤塞、洪水泛滥,由于城市无力供应干净能源,直接烧煤、烧柴造成空气污染,工厂用煤发电、没有对二氧化硫进行回收,造成空气中弥漫一氧化碳、二氧化硫粉末,出现酸雨损坏庄稼和建筑物的现象,由于城市垃圾、工厂废水来不及处理直接放入河道,使空气、水中及陆地上的生物受害造成生态不平衡,影响气候、影响人类健康生活条件,虽说我们国家地大物博,可是人均占有量占世界前列,这就要求我们对环境要做出适当的保护,我们即将跨入21世纪的大门,担当起主人的重任,我们能眼见着环境污染被破坏、而等闲视之吗?不,决不能,这就要求我们必须对环境做出适当的'保护。

  我们可以从身边一点一滴的小事做起,比如多植树造林,这就可以从根本上防止水土流失,爱护周围一草一木,不捕猎小动物等。但这些光凭我们的努力还不够,还要号召我们身边的每一个人为保护环境而做出贡献。

  先辈陆蠡说:“绿色是多么宝贵啊!它是生命、是希望、是安慰、是快乐。”徐霞客也曾说,遍及高山大川,迎风沐雨,为的是“多识鸟兽虫鱼之名”。前辈先哲的体验,都告诉我们大自然环境不仅能陶冶人的情操,净化和抚慰人的心灵,而且有助于知识的积累和事业的成功。

  朋友,当你受到“白天寂寞”和“黑夜孤独”煎熬的时候,当你陷入挫折和失意的时候,当你烦恼至及痛不欲生的时候,那么,你就走向大自然吧!那个时候你就会真正知道保护自然环境是何等重要。拥抱蓝天绿水,吻一吻泥土的芳香,在静静的山林中坐一坐,在绿色的草丛中坐一坐,顺手摘下一粒果子放在嘴里嚼一嚼,看看地上的蚂蚁不知疲倦的忙碌,都能使心绪渐渐平和,得到抚慰。你就会在大自然的真善美中,认识到你有你年轻的生命,你拥有一段生命的里程,激发你以丰富的知识和坚强的毅力去开拓一个美好的世界。

敬爱的老师,亲爱的同学:

  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13

  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14

  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 can't 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 people's 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.
