环境污染演讲稿 篇1

尊敬的老师们，亲爱的同学们：

大家好！

现代的人们大多数做饭用煤气、煤炉，舍弃了用稻柴烧火的时代，可他们不知道这样的行为大大污染了空气，污染了环境。尽管秀多人家烧菜时用吸油烟机，净化了家中的空气，但油烟机不可能完全吸入烟气，一部分烟气依然会流到空气中，一家人每天产生的烟气或许对大气污染没有什么影响，但是几十家、几万家、几亿家呢？几亿家产生的烟气汇集在一块难道仅有一点吗？难道就不会对空气产生污染吗？这个问题值得深思，我们必须静下心来好好反思，好好考虑。

一些地区沼气池进入人们的日常生活，沼气可以照明、取暖、做饭，这样不仅可以节约资源，而且还能减少对环境的污染、破坏，有利于大自然的和谐发展，有利于节约型社会的建设。

不光是大气污染，电池污染也成为当今的主要环境问题之一。许多人毫无环保意识，乱扔电池，随意把电池扔在垃圾桶里和其他垃圾混合在一起，不将垃圾分类，导致清洁工可能会随便处理这种有害垃圾。他们可曾知道，一只电池会污染一吨水，大大减小了水资源的现存量，我国不得不大力实行相关措施，净化水资源，可要挽救水需要多大的人力、物力、财力，这要花费多少我国的资金？所以，我们应该把垃圾分类，回收有用的垃圾，减少塑料袋、一次性快餐盒的使用，实行可持续发展战略，实行经济循环模式，合理利用资源，减少不可回收垃圾，减少对环境的污染，让地球成为一个更舒适的、更美丽的`家园。

一些工厂现在采用煤碳烧制东西，煤碳中含有二氧化硫，会形成酸雨，酸雨对环境有很大的污染，严重地破坏了大自然。人类无情地对待大自然，大自然也会给人类以报复，会造成许多的自然灾害。自然灾害会给人的生活带来很大影响，生活在这样一个受污染的环境中，不利于人的身心健康，也话在将来的某一天，地球会因我们犯下的罪行而毁灭。

不容置疑，为了保护我们的地球不被破灭，为了使我们的生活不受影响，我们必须增强环保意识，积极参加宣传环保活动。为了共同建设资源节约型社会，对现在存在的一些生活习惯应予根除，开发沼气和热水器等的使用，应迅速放到议事日程上来并且应迅速实施。

环境污染演讲稿 篇2

尊敬的老师，亲爱的同学：

大家下午好：

我的家乡在荆州。平时，我对家乡的环境也不大了解。这几天，我们班组织同学们进行了一次综合实践活动，对家乡的环境进行了一次调查，调查的主要对象是荆州的护城河。这次调查让我受益匪浅。

经过实地调查和上网查资料，我了解到以前的荆州护城河污染十分严重。护城河两侧共有二十多个排污口，每一天城区的生活及工业污水排入护城河，直接排入的总污水量约5万立方米。

所以，河水变成了浑浊的墨绿色。居住在附近的居民和过往的行人也很不爱护环境，把垃圾随随便便仍进河里，使河水的污染进一步加重。由于护城河是死水，无法流动，河底淤泥十分多，水面上漂浮着很多的蓝藻，河底的沉积物散发着臭味。人们从那里经过，都要捂着鼻子，加快脚步。

护城河的污染成为了荆州人的心中之痛。在广大市民的期盼下，市政府对护城河进行了彻底的治理。经过清淤、补水、截污、绿化……护城河面貌焕然一新。

如今的护城河碧波荡漾，波光粼粼。护城河宛如一面绿色的大镜子，映出了蓝天白云和古老城墙的.美丽倒影。几只鸭子在水面上嬉戏，几条小船在小河上悠闲地驶来驶去，真可谓“舟行碧波上，人在画中游”。河岸上杨枊依依，与古老的城墙交相辉映，美不胜收。

经过这次的环境调查，我增强了环保意识。我们必须要好好保护环境，让我们共同的家园天更蓝、水更清、景色更美! 关于环境污染的演讲稿 第11篇

敬爱的老师、同学们：

大家早上好！我是xxx。今天我讲的题目是：低碳生活，共抗雾霾。

同学们一定对不久前南京成了“雾都”记忆犹新。雾霾天气逐渐加重，影响到了我们正常的生活，危害了我们的身体健康。那什么是雾霾呢？雾霾，雾和霾的统称。雾霾的主要组成部分是可吸入颗粒物，也就是我们众所周知的PM2.5。这些颗粒散播在大气中，影响了空气质量，加剧疾病传染，威胁着人们的身体健康。雾霾天气属于严重空气污染事件，污染物排放量大是根本原因。因此，爱护保护我们的生活环境，应是每个公民应自觉遵守的。 在这样的雾霾天气里，戴什么口罩成了大家的热点。在大街上，许多人都是戴卡通口罩或医生专用蓝色口罩，但这些口罩对于PM2.5颗粒基本起不到什么作用，建议大家最好戴N95口罩或“猪嘴”型的口罩，这样的口罩戴起来会紧紧贴着皮肤，雾霾不会进去，就算在PM2.5爆表的时候也会起到很大的作用。另外，我要提醒大家哦，戴完口罩后，应及时清洗，以免滋生细菌，而且佩戴时间不宜过长，这样可能会导致呼吸困难或头昏等症状。

在这样的雾霾天气里，我们又应该吃什么呢？其实，在这样的季节里最好能吃清淡食品，多吃蔬菜水果，尤其是胡萝卜，因为胡萝卜有着让大肠通常以及杀菌的作用，能有效抵抗雾霾。那我们又该喝什么呢？推荐大家一早起来能够喝一杯热的白开水、蜂蜜水或柠檬水，这样有助于清洗肠道、清润喉咙的作用。

另外，我们还应该做好个人卫生。我们进入室内后要及时洗脸、漱口、清理鼻腔，去掉身上残留的颗粒。洗脸时，我们应用热水洗；漱口时，也最好用热水；清理鼻腔时，最好利用热水用鼻子轻轻吸水并迅苏擤鼻涕，同时也要避免呛咳。

同学们，让我们从现在做起，从自身做起，用实际行动，来诠释低碳的生活方式，与危害我们健康的雾霾做斗争！

谢谢大家，我的演讲结束了。

环境污染演讲稿 篇3

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。

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

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.
