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!

关于核污染的演讲稿篇2

1. power generation

siting fossil fuel power stations in mainly rural areas and distributing the pollution produced more evenly via tall chimneys has resulted in improved urban air quality though they still remain a major source of pollution mainly sulphur dioxide and nitrogen oxides.

better dispersion of pollutants emitted by tall chimneys leads to better dilution in the air and thus lower local concentrations of pollutants. this has however led to pollution being dispersed more widely and to transboundary air pollution.

2. other industry and waste disposal

although fossil fuel power plants are the major source of industrial air pollution in many countries all industry and many businesses large and small can be significant local sources of a wide range of air pollutants.

all waste has the potential to affect the environment adversely by contaminating the air soil or water. poorly managed waste disposal sites (landfill or incineration) can also pose a danger to public health through all these routes.

3. road transport

air pollution from motor vehicles has in many countries replaced coal smoke as the major cause for concern; and the continuing growth in vehicle use means that efforts to reduce emissions from individual vehicles are in danger of being overtaken by increases in the volume of traffic.

the air pollutants produced as a result of the use of motor vehicles present a two-stage problem: primary and secondary pollutants. primary pollutants produced by petrol-powered vehicles include carbon monoxide nitric oxide benzene particulate matter and lead. much of the lead emitted by vehicles burning leaded petrol emerges as particles. secondary pollutants produced as a result of the use of petrol-engined vehicles include nitrogen dioxide and ozone.

4. domestic sources

as temperatures across the region plummeted domestic burning of coal across northern china becomes the primary source of air pollution. other important domestic sources of air pollution are:

stoves and cookers produce carbon monoxide. if ventilation is inadequate or appliances poorly maintained co may accumulate in dangerous concentrations. nitrogen dioxide is also generated and concentrations in kitchens will usually exceed those outdoors when cookers are in use.

bonfires garden incinerators and barbecues can be a significant local smoke and odour nuisance. burning garden waste produces smoke especially if it is damp and smouldering rather than dry and blazing. the smoke contains co and other noxious and irritating compounds. problems may be caused for asthmatics bronchitis sufferers or those with heart conditions. even if the immediate health risk is small bonfires add to the general background level of air pollution.

5. agriculture

agricultural practices can also be a significant source of nuisance contributing both to local levels of air pollution and causing odour problems. the main sources of pollution are the burning of agricultural waste or of crops in the field and large intensive livestock units. depending on soil type and fertilisation the nitrogen in the dung and urine of grazing cattle contributes 20-40% of nitrous oxide emissions from agricultural land; methane is also emitted by cattle and other ruminants; nitrous oxide and methane are of course both greenhouse gases.

关于核污染的演讲稿篇3

尊敬的老师们，亲爱的同学们：

大家好！

在一片清澈的池塘里，鲤鱼国王和他的子民们其乐融融地生活在一起。鱼儿们在荷叶下玩捉迷藏；小虾小蟹们在池底打闹、嬉戏。一朵朵白中透粉的荷花姐姐，对着水镜，打扮自己。池面在阳光的照射下像撒了金子一样。看过这儿的人，都会发出感叹：好美啊！我也想做一条鱼和他们生活在一起！

可是，有一天，不幸降临了。鱼儿们死的死，伤的伤，池里的荷花姐姐都难逃一劫。桂鱼大臣惊惶失措地去向鲤鱼国王报告：“陛下，大事不好啦！子民们死伤无数！”鲤鱼国王大惊，说：“子民们一向很健康，怎么会这样？”桂鱼大臣说：“回陛下，据陆军队长乌龟回报，人类的池边建造了许多工厂，他们将大量的废水排放至此。环境污染，子民们喝了被污染的水后，都中毒啦！”鲤鱼国王大怒，说：“竟然有这样的事！速速召集所有的大臣前来商议此事！”

不一会儿，乌龟队长、泥鳅大将、龙虾大帅、螃蟹宰相和桂鱼大臣聚集一堂。

鲤鱼国王严肃地说：“你们也知道，最近我国子民们喝了污水后，死伤无数。现在，我们必须找一个清澈的水湾，搬到那儿去。众爱卿有什么建议？”泥鳅大将道：“方圆三百里外有一个小水湾，那儿的水还很清。”鲤鱼大王决定：“明天先派人去查看，然后迅速搬迁！”

第二天，鲤鱼国王派出三名陆军队队员——三只小青蛙去探寻。他们走啊走啊，不料，在途中遇到了一群野炊的人。其中两只被烤着吃了，还有一只青蛙历尽艰险，死里逃生，终于找到了那个小水湾。可惜，小水湾也被污染了。他返回时，累死在途中。

一天，两天，三天……寻找生命之池的小青蛙没有回来。活着的鱼儿们已经渴得有气无力。有的索性喝下毒水，悲惨地死去。有的苍惶地逃离这个池塘。往日美丽的小池塘变得死气沉沉，而人类却还是在放肆地污染着池塘。池底之国已经不复存在了，取而代之的是一池再也泛不起一丝涟漪的死水……

关于核污染的演讲稿篇4

许多人认为，地球上海，陆，空的资源是取之不尽的。他们毫无顾忌地把千万吨的废气排放到空中，把数亿吨的垃圾，污水排放到大海……

我看到成群的鸟儿在森林上空盘旋，但是，今天那一棵棵高耸入云的大树——鸟儿的乐园，只剩下一排排低矮的树墩。我仿佛听到小溪里的鱼儿在哭泣，人们把污水排放到小溪，鱼儿纷纷死去。仰望天空，一根根高大的烟筒冒出滚滚浓烟。

俯视大地，小草已经枯黄，地上到处是垃圾。

天空不再蔚蓝，草儿不再嫩绿，花儿不再娇艳，溪水不再清澈见底。

我们要保护地球，保护地球上的`生态环境，相信不久的将来，地球会恢复往日的神采！

关于核污染的演讲稿篇5

有许多事情，大家是不能忘记的。其中有一件事情我一提起，每一个内江人都还记忆犹新，那就是去年的沱江河水污染。

阳春三月，发生了一起河水污染事件，让美丽的沱江河成为了一条哭泣之河。从2月16日到3月2日川化二厂向沱江河排放纯氨氮20xx吨，河水发出恶臭，氨氮指标超标40-50倍，上游河段达到100倍，这可是惊人的数字呵，会致人怪病甚至患上癌症的，已造成了大规模死鱼，死鱼达50万公斤，沱江生态受到严重破坏，直接经济损失上亿元，致使简阳、资阳、内江百万居民停饮自来水。这是全国近年来最大的水污染事件。因为时间持续到3月2日，被称为“302”事故。现在时间虽然已过去一年多，排污工厂受到了处罚，工厂排污得到遏制，但河边污染水源的情况并未停止。河滩上到处都有烟头、纸屑、果皮、塑料袋等各种垃圾在污染河水。

针对现在的河水污染情况，我想，如果我是市长，我将会采取以下几种办法治理污染。

一、河滩放置垃圾桶。我发现现在河边没有垃圾桶，只有河堤上才有，而人们都有一种懒惰心理，丢一次垃圾要花几分钟，很麻烦，大多数人就干脆把它丢在河里和地上。就近在河滩放置几个垃圾桶，又花不了多少钱，简便易行，解决了人们丢垃圾麻烦的问题。

二、河滩设置管理人员。现在人们不想把垃圾丢进垃圾桶还有一个原因，就是人们发觉河滩没有人员管，可以乱丢垃圾，造成环境污染。安置管理人员强制管理人们的不卫生习惯。

三、加强环境保护的宣传教育。现在人们乱丢垃圾的另一个原因是环保意识差。要在办公室、学校等公共场所进行宣传，提高人们的环保观念。学校也可经常组织学生到河滩捡拾垃圾，增强学生的环保自觉意识。

四、多植树木，防止水土流失。大家知道黄河是怎么来的吗?就是因为它流过的地方有黄沙流失，积少成多，慢慢就成了黄河。如果我们多植树木，就可以防止河岸上泥土流失，以免成为第二条黄河。

能按这样做，我相信一年内沱江河将成为最干净的河。

现在我们应该保护水资源，防止沱江河发生第二次河水污染。

有了水，才构成这个蔚蓝的星球;有了水，整个世界才有了生命的气息;有了水，我们的世界才变得生机盎然;有了水，我们才有了秀美的山川、清澈的溪水、湛蓝的海洋……我们才有了一切。

关于核污染的演讲稿篇6

地球是我们人类的家园，也是人类的母亲。我们依赖它，探索它。这个蔚蓝色的星球多么美丽，但我们要知道：地球只有一个！

遗憾的是，许多人对于这个浅显易懂的道理却视而不见，继续为所欲为，妄顾地球家园的安危。环境科学家曲格平曾经说过这样一句话：“唯有变革，才能拯救人类的命运，也唯有变革，才能使我们的子孙后代世世代代生存下去。”里面的“变革”就是指环保。说得很对，所以如今有许多人拿着标语在街上喊空口号，却没有见过多的行动。难道这样污染就会好转吗？不！

看，我们城市里的河流的河水发黑发臭；排成长龙的汽车放出大量的废气；成片的绿地变成“石屎森林”；那清脆的鸟叫声消失得无影无踪。如果再这样下去，中国将继续贫乏水资源，空气将变得愈来愈浑浊，本世纪将有10%的鸟类物种消失。上述的事情，我们人类是罪魁祸首！

人人皆知：树木能吸收二氧化碳，排放氧气，净化空气，是我们人类生存的必要的条件。但是有一些人为了金钱去乱砍滥伐树木，造成了过度的水土流失，使大地的植被受到严重的破坏，绿洲和城市也荒漠化，我们人类的生存受到了威胁。就我们平时用的一次性筷子，每天都要耗费数十亩的森林，在那些人眼中，树木除了可以做家具和建筑材料外，似乎没有任何价值。难道还有人不懂树木对我们意味着什么吗我们居住面积已经很小了，如果再这样下去，可能连我们的土地都失去。还有，我们的母亲河——黄河近年来河床和含沙量不断增高，成为全国污染最严重的几条江河之一。我们不能眼睁睁地看着黄河从我们手中枯竭，因而有许多环境学者纷纷研究治理黄河污染的方案，试图改善黄河的水质。但如果没有我们的共同参与，我们这个生命的摇篮——黄河将会走向衰竭和死亡。

如果我们再肆无忌惮地破坏环境，大自然将会给予我们惩罚。那些特大的洪水剥夺了不知多少人的性命，还有由于温室效应，南极北极的冰川融化导致水平面升高，海水淹没了沿海地区，经济损失惨重。难道这不是的证明吗

我的家乡广宁是靠竹海生态旅游来发展经济的，而今，某些竹林的环境恶乱不堪，让人叫苦不迭。竹海生态游是我们广宁发展的根，如果根被破坏了，怎能长出茂盛的枝叶、开出美丽的花儿呢

让我们善待人类、善待自然吧！不知大家是否看过《保护环境可做的100件事》这篇文章。其实，我们能做的事很多很多。如，在植树节栽一盆花、种一棵树；保护野生动物，是生态得到平衡；珍惜水资源，不要向江河倾倒垃圾；当环保小卫士，利用每个绿色纪念日宣传环保意识，让青山常在、绿水长流、泥土永芬芳……这都是我们力所能及的事情，我们为何不愿意实践呢？

现在，地球的生态环境加剧恶化，环保警世钟已经敲响了。让我们齐齐加入保护环境的行列，创立一个人与大自然和谐共处的美好未来，让人类与自然生生不息地繁衍下去吧

关于核污染的演讲稿篇7

pollution in the ocean is a major problem that is affecting the ocean and the rest of the earth, too. pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. people should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.

what are toxic wastes?

toxic wastes are poisonous materials that are being dumped into the ocean. they harm many plants and animals in the ocean and have a huge impact on our health. toxic waste is the most harmful form of pollution to sea life and humans. when toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. in the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.

many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. one of the most harmful chemicals in the ocean is lead. lead can cause many health problems. it can damage the brain, kidneys, and reproductive system. lead can also cause birth defects for people. it has been shown to cause low iq scores, slow growth, and hearing problems for small children. house and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.

many things found in the ocean may cause seafood to be dangerous to human health. the effect on humans from contaminated seafood may include birth defects and nervous system damage. medical waste found in the ocean is being tested to see if swimmers have a chance of developing hepatitis or aids. other waste has been known to cause viral and bacterial diseases. this type of pollution can be stopped by watching what pollution we are letting into the ocean. people are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.

boating pollution prevention tips

whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. boating pollution is the pollution that comes from the boatsquo;s engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. the engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. in order to make as little pollution as possible, what everyone can do to help is:

only turn a boat engine on all the way when you need to.

donsquo;t take your boat out into the water if you donsquo;t need to.

be sure to store and transport gasoline in places where there isnsquo;t any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air.

every year, buy new or cleaner marine engines for your boats.

garbage dumping

garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. most of the waste that has been dumped into the ocean in the early 1990squo;s is still there today. one main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. after that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animalsquo;s neck, causing it to suffocate), and makes the water dirty.
