環境污染演講稿1
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.

尊敬的老師、同學們：
大家好!
就最近這幾年來看，隨著各地區的經濟迅猛發展，環境污染問題也越來越嚴重，保護環境，維持生態平衡也成為了我們每個公民應盡的職責和義務，也是為了社會更好發展的一項重要舉措!何為環境從哲學的角度來看，所謂環境，主要指我們所研究的主體周圍的一切情景和條件。對于人來說，環境是指人生活于其中，并
能影響人的一切外部條件的綜合。人的生活離不開好的環境，在人類幾百萬年的歷史進程中，環境對開創人類禮貌和提高發揮著巨大作用。
大氣資源、水資源、土地資源等等，都是讓人類得以生存的物質基礎;而森林資源、礦藏資源等資源又為人類的不斷發展供給物質，創造出地球上高度的人類禮貌。可是，人類在開發利用環境資源的同時，也對自我的生存環境產生了一系列環境問題。
在我們身邊就有很多污染環境的污染物，例如說：很多的生活廢棄品，塑料袋(也稱白色垃圾)，一次性木筷，一次性飯盒，果皮紙屑。污染物對環境來說，毫無疑問，肯定有很大的危害，例如動物的腐爛的尸體會影響環境衛生，并且還會滋生細菌。飯店、餐館認為很衛生的一次性木筷，使用后隨便一扔，影響了市容，破壞了環境。。
此刻像我們柳疃鎮、青鄉鄉，最近電網部門紛紛撤除噴水機器的使用。噴水機的使用對環境的污染更加惡化、污染了水資源對人們的'身體健康危害甚大。人類的活動會使很多的工業、農業和生活廢棄物排入水中，使水受到污染。又例如說，我們北部渤海灣受到工業、印染廠的廢棄物排放很多魚蝦死亡，地區農民上海捕魚，魚的體內包含很多化學物質對人們的身體健康造成了危害。據資料統計，目前，全世界每年約有4200多億立方米的污水排入江河湖海，污染了5.5萬億立方米的淡水，這相當于全球徑流總量的14%以上。
1984年頒布的中華人民共和國水污染防治法中為“水污染”下了明確的定義，即水體因某種物質的介入，而導致其化學、物理、生
物或者放射性等方面特征的改變，從而影響水的有效利用，危害人體健康或者破壞生態環境，造成水質惡化的現象稱為水污染。水的污染有兩類：一類是自然污染;另一類是人為污染。當前對水體危害較大的是人為污染。水污染可根據污染雜質的不一樣而主要分為化學性污染、物理性污染和生物性污染三大類。
最近，我發現政府部門、昌邑環衛局開始大力整治環境，沿街排查污染源，青鄉街也定點安置了便民垃圾桶，替代了原先垃圾圍繞街道，臭氣熏天的狀況。各個村莊開始整治村內環境的污染源，使街道、村莊煥然一新!而這不是主要的，更重要的是我們每個人自覺保護環境，保護我們賴以生存的家園，為了我們更為了我們的后代，樹立好榜樣，奠基好基礎，讓我們的家園更加美麗、更加豐富多彩!所以呢!環境與我們的生活密切相關，保護環境衛生從我做起，從此刻做起：不隨地吐痰;不亂扔垃圾;廢棄電池和塑料袋要處理好;多植樹造林，不踐踏草坪;不污染水源。保護環境，我們有責!看你的行動嘍!
環境污染演講稿3
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.
環境污染演講稿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.
環境污染演講稿5
未來10年，33%家庭將為恢復健康傾家蕩產！親們，為健康，為未來開始未雨綢繆吧!
未來十年，中國將出現癌癥井噴，中國33%的家庭將耗盡所有的積蓄，到底是誰偷走了我們的健康？
我們把所有的空閑時間用來休息，卻總是感覺疲勞。
醫院的樓蓋的一年比一年高，可是病人卻越來越住不下了，醫院的設備一年比一年先進了，可是很多病卻查不出來了，藥品的種類一年比一年全了，可是吃了卻不管用了……第一：水污染第二：空氣污染
我們的空氣污染遠遠超出我們所知道的，就不說臭氧層，就說PM2.5，很多的城市都不合格！世界上污染最嚴重的城市有一半以上在中國。今年一月份的北京有一半時間都是重度污染！中國患肺癌死亡的人數已經上升到所有癌癥的首位，這和抽一手煙、二手煙、汽車尾氣、室內裝修...
第三：土地污染
我們的土地重金屬污染極其嚴重！多年農藥和化肥的使用，使土地的肥力下降，農藥殘留還嚴重威脅到我們的健康，首先遭殃的就是我們的肝臟，肝臟具備解毒功能，最先被危害！
更重要的是我們吃的東西存在很多的問題！
①人體每天需要攝入5-13份的.蔬菜和水果。目前蔬菜冷藏技術發展，讓我們隨時都可以吃到鮮菜，大棚蔬菜，反季節蔬菜等多不勝數，農藥，除草劑，化肥等等數不勝數
②激素濫用：以前豬是10個月出欄，現在5個月就出欄了；雞以前
3、5個月長成，現在通過激素和抗生素的喂養，只需40天就可長到5斤多重，激素催熟成了不辯的實事。 ③抗生素的濫用：也使我們的營養素流失嚴重！抗生素危害到我們的肝、腎，而維生素、蛋白質等
如果你不想在10年后，用辛苦打拼換來的財富，拯救自己的健康。請現在就行動起來，學會保護環境，減少污染；開始低碳生活，綠色出行；學會運動養生，健康飲食；關注“生命之源”，擁抱健康生活。
環境污染演講稿6
環境（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（人口增長）
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（全球變暖）
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（臭氧層變薄）
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（空氣污染）
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（物種滅絕）
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（化學成分污染）
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（環境歧視）
環境污染演講稿7
Iam worried about my country. There is polution everywhere. Itis time to do something about it. We need fresh air to breathe. We need pure water to drink. We need a clean environment to be healthy. People have to stop littering. We have to respect our surroundings. We must become friends of the earth. First,everyone must get involved. Everyone must lend a hand. Together we can clean up our neiborhoods. Second,we can practice conservation. We can reduce waste and reuse things. We can recycle paper,bottles,and plastic. Third,we can put up more "Don't litter" signs. We can trashcans on every corner. We can pick up garbage when we see it. We must take action to fight pollution. It's our future we're protecting. It's our duty to keep our planet clean. So,please don't pollute. Don't be a litterbug. Don't be afraid to remind others,too. Let's protect nature's beauty. Let's make our future bright. Let's start to clean up now.

尊敬的老師們，親愛的同學們：
大家好！
現代的人們大多數做飯用煤氣、煤爐，舍棄了用稻柴燒火的時代，可他們不知道這樣的行為大大污染了空氣，污染了環境。盡管秀多人家燒菜時用吸油煙機，凈化了家中的空氣，但油煙機不可能完全吸入煙氣，一部分煙氣依然會流到空氣中，一家人每天產生的煙氣或許對大氣污染沒有什么影響，但是幾十家、幾萬家、幾億家呢？幾億家產生的煙氣匯集在一塊難道僅有一點嗎？難道就不會對空氣產生污染嗎？這個問題值得深思，我們必須靜下心來好好反思，好好考慮。
一些地區沼氣池進入人們的日常生活，沼氣可以照明、取暖、做飯，這樣不僅可以節約資源，而且還能減少對環境的污染、破壞，有利于大自然的和諧發展，有利于節約型社會的建設。
不光是大氣污染，電池污染也成為當今的主要環境問題之一。許多人毫無環保意識，亂扔電池，隨意把電池扔在垃圾桶里和其他垃圾混合在一起，不將垃圾分類，導致清潔工可能會隨便處理這種有害垃圾。他們可曾知道，一只電池會污染一噸水，大大減小了水資源的現存量，我國不得不大力實行相關措施，凈化水資源，可要挽救水需要多大的人力、物力、財力，這要花費多少我國的`資金？所以，我們應該把垃圾分類，回收有用的垃圾，減少塑料袋、一次性快餐盒的使用，實行可持續發展戰略，實行經濟循環模式，合理利用資源，減少不可回收垃圾，減少對環境的污染，讓地球成為一個更舒適的、更美麗的家園。
一些工廠現在采用煤碳燒制東西，煤碳中含有二氧化硫，會形成酸雨，酸雨對環境有很大的污染，嚴重地破壞了大自然。人類無情地對待大自然，大自然也會給人類以報復，會造成許多的自然災害。自然災害會給人的生活帶來很大影響，生活在這樣一個受污染的環境中，不利于人的身心健康，也話在將來的某一天，地球會因我們犯下的罪行而毀滅。
不容置疑，為了保護我們的地球不被破滅，為了使我們的生活不受影響，我們必須增強環保意識，積極參加宣傳環保活動。為了共同建設資源節約型社會，對現在存在的一些生活習慣應予根除，開發沼氣和熱水器等的使用，應迅速放到議事日程上來并且應迅速實施。

尊敬的老師，親愛的同學們：
大家好！我是六（2）班的鄭倩琦。
我演講的題目是《保護環境，從我做起》這些年來。我們國家受到了嚴重的環境污染，特大沙塵暴在我國一次又一次發生，它將會掩埋草地、吞毀家園，嚴重地影響了人民的生活，使我們難以生存。綠色的草地將會變成沙漠，大樹將會永遠臥倒在地，而我們也不會快樂生活：幸福沒有了，親人沒有了，連我們賴以生存的地球也會在茫茫宇宙中粉碎，就像玻璃摔在地上一樣。然而這不僅是沙塵暴帶來的災難。
現在，連南極也遭到了污染破壞。因此，地球上失去了最后一塊凈土。泰山原來是被人們觀賞的好地方，居然也成了保護區。
而我們，難道就只能袖手旁觀嗎，難道我們只能看著這美麗而脆弱的地球永遠消失在人間嗎？從此，我們能看到風吹草地見牛羊，白云下面馬兒跑的那種景象嗎？我們能為地球媽媽做些什么呢！ 那就從身邊的小事做起吧。當你和家人出去旅游時，不但自己不亂扔果皮，包裝紙，而且發現垃圾還能主動揀起來投進垃圾箱里，那你就是一個保護環境的好少年；在學校里，看見自來水龍頭沒關緊，你能上前動手把它擰緊；看到光線充足，能主動把燈關掉，那你就是一名節約資源的.好學生……只要大家都做一個愛護環境的有心人，就能為我們的家園盡一份力，添一片綠，將來就能把地球建成一個更加美好和諧的新家園。
保護環境，從我做起，從身邊的小事做起，讓我們的家園在希望中崛起吧。
謝謝大家，我的演講結束了。

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.

親愛的同學們：
大家好!
這天我要演講的題目是：愛護環境。
愛護環境是每個人的職責，社會無論如何進展，人類都得成認一件事實，那就是大自然是人類的母親，我們呼吸一口空氣，喝的每一滴水，都離不開自然。人類賴以生存的星球只有地球。
但是，人類像一個貪欲的孩子，只顧索要，不管回報，以至于此刻的環境傷痕累累，長此以往，受傷的必將是我們人類自己……
瞧!假如不愛護環境，大自然母親也將會發怒，比方5.12大地震，日本大地震，泥石流災難等，在這過程中，有多少人失去的親人，失去了無法估量的財產，這不是大自然對人類的懲處嗎?
我們身邊觸目驚心的事例歷歷在目，如：路邊的.小樹被折，小草被踐踏，小花被采摘，莫非他們不痛，不悲傷嗎?亂砍濫伐，無克制的開采礦產資源。人們就是這樣，無所事事的破壞生態平衡。作為小學生，我們就應從身邊做起，從小事做起，愛護花草樹木，不亂丟垃圾，不使用一次性筷子，盡自我一份微薄之力。
在此我呼吁大家;請愛護環境，只有這樣才是最終愛護了人類自己!由于地球只有一個，人類不能克隆。
我的演講到此完畢，感謝大家!
環境污染演講稿12
教師們，同學們早上好!今日我演講的題目是愛護環境，從我做起。
同學們，我們的家園富裕而漂亮，我們生活，學習的地方空氣是那樣的清爽，環境是那么的美麗。地球就像媽媽一樣給我們帶來幸福，帶來歡樂。可是，你們知道嗎?我們生活的地球上，美妙的環境正在遭到破壞，它將給我們人類帶來無窮的災難。
我們少先隊員能為地球媽媽做些什么呢?那就從身邊的小事做起吧。當你和家人出去旅游有愛惜環境的有心人，就能為我們的.家園盡一份力，添一片綠，將來就能把地球建成一個更加美妙和諧的新家園。
同學們，你們看，由于有了我們的參加，青山非常地蔥郁;由于有了我們的行動，綠水非常地清亮;由于有了我們的存在，地球媽媽欣慰地笑了!
感謝大家!

尊敬的老師們，親愛的同學們：
大家好！
地球是我們人類的家園，也是人類的母親。我們依賴它，探索它。這個蔚藍色的星球多么美麗，但我們要知道：地球只有一個！
遺憾的是，許多人對于這個淺顯易懂的道理卻視而不見，繼續為所欲為，妄顧地球家園的安危。環境科學家曲格平曾經說過這樣一句話：“唯有變革，才能拯救人類的命運，也唯有變革，才能使我們的子孫后代世世代代生存下去。”里面的“變革”就是指環保。說得很對，所以如今有許多人拿著標語在街上喊空口號，卻沒有見過多的行動。難道這樣污染就會好轉嗎？不！
看，我們城市里的河流的河水發黑發臭；排成長龍的汽車放出大量的廢氣；成片的綠地變成“石屎森林”；那清脆的鳥叫聲消失得無影無蹤。如果再這樣下去，中國將繼續貧乏水資源，空氣將變得愈來愈渾濁，本世紀將有10%的鳥類物種消失。上述的事情，我們人類是罪魁禍首！
人人皆知：樹木能吸收二氧化碳，排放氧氣，凈化空氣，是我們人類生存的必要的條件。但是有一些人為了金錢去亂砍濫伐樹木，造成了過度的水土流失，使大地的植被受到嚴重的破壞，綠洲和城市也荒漠化，我們人類的生存受到了威脅。就我們平時用的一次性筷子，每天都要耗費數十畝的森林，在那些人眼中，樹木除了可以做家具和建筑材料外，似乎沒有任何價值。難道還有人不懂樹木對我們意味著什么嗎我們居住面積已經很小了，如果再這樣下去，可能連我們的土地都失去。還有，我們的母親河——黃河近年來河床和含沙量不斷增高，成為全國污染最嚴重的幾條江河之一。我們不能眼睜睜地看著黃河從我們手中枯竭，因而有許多環境學者紛紛研究治理黃河污染的方案，試圖改善黃河的水質。但如果沒有我們的共同參與，我們這個生命的搖籃——黃河將會走向衰竭和死亡。
如果我們再肆無忌憚地破壞環境，大自然將會給予我們懲罰。那些特大的洪水剝奪了不知多少人的性命，還有由于溫室效應，南極北極的冰川融化導致水平面升高，海水淹沒了沿海地區，經濟損失慘重。難道這不是的證明嗎
我的家鄉廣寧是靠竹海生態旅游來發展經濟的，而今，某些竹林的環境惡亂不堪，讓人叫苦不迭。竹海生態游是我們廣寧發展的根，如果根被破壞了，怎能長出茂盛的枝葉、開出美麗的花兒呢
讓我們善待人類、善待自然吧！不知大家是否看過《保護環境可做的`100件事》這篇文章。其實，我們能做的事很多很多。如，在植樹節栽一盆花、種一棵樹；保護野生動物，是生態得到平衡；珍惜水資源，不要向江河傾倒垃圾；當環保小衛士，利用每個綠色紀念日宣傳環保意識，讓青山常在、綠水長流、泥土永芬芳……這都是我們力所能及的事情，我們為何不愿意實踐呢？
現在，地球的生態環境加劇惡化，環保警世鐘已經敲響了。讓我們齊齊加入保護環境的行列，創立一個人與大自然和諧共處的美好未來，讓人類與自然生生不息地繁衍下去吧。
許多人認為，地球上海，陸，空的資源是取之不盡的。他們毫無顧忌地把千萬噸的廢氣排放到空中，把數億噸的垃圾，污水排放到大海……
我看到成群的鳥兒在森林上空盤旋，但是，今天那一棵棵高聳入云的大樹——鳥兒的樂園，只剩下一排排低矮的樹墩。我仿佛聽到小溪里的魚兒在哭泣，人們把污水排放到小溪，魚兒紛紛死去。仰望天空，一根根高大的煙筒冒出滾滾濃煙。
俯視大地，小草已經枯黃，地上到處是垃圾。
天空不再蔚藍，草兒不再嫩綠，花兒不再嬌艷，溪水不再清澈見底。
我們要保護地球，保護地球上的生態環境，相信不久的將來，地球會恢復往日的神采！
環境污染演講稿14
同學們，你見過樹嗎？不，你見過的是街道兩旁或公園里的樹，單調、乏味、黑不溜秋。你見到水嗎？不，你見過的是人工湖的水，渾濁、發臭、游人洗過腳的。你見過鳥嗎？不，那是籠中之鳥，呆呆的、只會要吃的。 近年來，隨著經濟的發展、社會的進步，我國的環境也隨之變化，大自然受到嚴重的破壞，如果我們還不行動起來，保護環境
，那么在未來的某一天，我們頂會瀕臨動植物滅絕的.死亡線上。
由于我國人口素質還不夠高，對生態系統缺乏認識、不了解自然規律，近年來，我國的自然環境和生態平衡已經遭到嚴重的破壞。比如為取暖、做飯、蓋房子大量破壞森林，進而造成水土流失、河道淤塞、洪水泛濫，由于城市無力供應干凈能源，直接燒煤、燒柴造成空氣污染，工廠用煤發電、沒有對二氧化硫進行回收，造成空氣中彌漫一氧化碳、二氧化硫粉末，出現酸雨損壞莊稼和建筑物的現象，由于城市垃圾、工廠廢水來不及處理直接放入河道，使空氣、水中及陸地上的生物受害造成生態不平衡，影響氣候、影響人類健康生活條件，雖說我們國家地大物博，可是人均占有量占世界前列，這就要求我們對環境要做出適當的保護，我們即將跨入21世紀的大門，擔當起主人的重任，我們能眼見著環境污染被破壞、而等閑視之嗎？不，決不能，這就要求我們必須對環境做出適當的保護。
我們可以從身邊一點一滴的小事做起，比如多植樹造林，這就可以從根本上防止水土流失，愛護周圍一草一木，不捕獵小動物等。但這些光憑我們的努力還不夠，還要號召我們身邊的每一個人為保護環境而做出貢獻。
先輩陸蠡說：“綠色是多么寶貴啊！它是生命、是希望、是安慰、是快樂。”徐霞客也曾說，遍及高山大川，迎風沐雨，為的是“多識鳥獸蟲魚之名”。前輩先哲的體驗，都告訴我們大自然環境不僅能陶冶人的情操，凈化和撫慰人的心靈，而且有助于知識的積累和事業的成功。
朋友，當你受到“白天寂寞”和“黑夜孤獨”煎熬的時候，當你陷入挫折和失意的時候，當你煩惱至及痛不欲生的時候，那么，你就走向大自然吧！那個時候你就會真正知道保護自然環境是何等重要。擁抱藍天綠水，吻一吻泥土的芳香，在靜靜的山林中坐一坐，在綠色的草叢中坐一坐，順手摘下一粒果子放在嘴里嚼一嚼，看看地上的螞蟻不知疲倦的忙碌，都能使心緒漸漸平和，得到撫慰。你就會在大自然的真善美中，認識到你有你年輕的生命，你擁有一段生命的里程，激發你以豐富的知識和堅強的毅力去開拓一個美好的世界。
環境污染演講稿15
敬愛的教師，親愛的同學：
大家好：
最近幾天，我著重觀察了周圍的環境，發現有很多方面都十分得不好，經過仔細分析，主要有以下幾點不足：
1、街道、居民區、鬧市區和馬路上的垃圾很多，包裝紙、塑料袋隨處可見。風一刮起來，這些垃圾就隨著沙土一齊飛揚，“襲擊”著路人。
2、空氣不清新，污染嚴重，使得病菌們更囂張跋扈的.在春季橫行，很多人都染上了感冒和一些呼吸道疾病。
3、大街上會有一些小販弄得地面很不干凈，每當他們收攤回家，總能看見地上散落著一些魚鱗、爛菜葉、爛水果，這些東西不僅僅影響市容市貌，還會不時地發出刺鼻的臭味，有時還會妨礙交通。
之后，我左思右想，家鄉的環境變成這樣，不就因為我們自我嗎路上會有那么多垃圾，還不都是市民們為了一時的方便，吃完東西后隨手就扔，對路邊的垃圾桶視若無睹，并沒有很強烈的環保意識，才會亂倒亂扔垃圾的。
雖然政府已經嚴禁一些工業排廢水、廢渣、廢氣了，可是還有些民辦企業總是污染環境。難道他們在謀取暴利的時候，沒有看到那煙囪里冒出的黑煙嗎家鄉的拒馬河不就是一個鮮活的例子嗎以往是“拒馬長虹，雙塔青煙”的家鄉，如今已被破壞的體無完膚。隨著科學技術的提高和社會的發展，機動車越來越多，空氣污染指數越來越高，我們該怎樣生活啊!
所以，讓我們從小事做起，來保護環境，保護我們共同的家園吧!
