know you today from the 2009, let me do a return tour, you tour in 2030 with the "ocean", i think you must be harvested. as we all know, oceans of the earth's seven tenths, very serious marine pollution in 2009, but in 2030, due to advanced science and technology, "decontamination robot" has become the bane of marine pollution, so, when there is no pollution in the ocean. now, i take you first "multi-functional reception", and replace "changes in the marine location device", it all took us off to another world. today's oceans, is home to human beings, 50 percent of people worldwide live in the ocean, you will find it very curious about how to survive in the ocean? fact well, sea world, where there is an "oxygen control room," oxygen produced from here, through the "oxygen cylinder" sent to every corner of ocean, people breathing in fresh oxygen, emit carbon dioxide, and then by the "oxygen control room" to receive, but also to create such a cycle of oxygen ... ....

harbour fish is strange, since the sea water into fresh water, the fish learned human language, but also to talk with people it can be fun! you to the front of a large group of fish, fish said: "good morning!" fish will speak english, i am really not believe it. listen to my introduction to you on the residential areas. although before you see is a blank, but people live here. the sea and land were not the same person, they food is simple, a "simple food dan" can be over 100 days, so they are very relaxed. live it? to four "sea" as their home, think of where to sleep on where to sleep, carefree.

then, you visit the royal palace, park ... ... must have felt very grand, magnificent it! perhaps you worry about, so many people living in the seabed, the environment will not occur the problem? not. harbour achieved without factory, but there are production. and no worse than the production of the land, because we row down the waste land, water, through the "decontamination robot" "pass" "make the robot" for processing, making available all kinds of things ... ... strange, wonderful sea world tour finished, how? i am sure you will feel the power of science is so magical.

核污染演讲稿篇2

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……

teachers students:

hello everybody

today i lecture on the topic of air pollution. air pollution is a new branch of atmospheric science it is to study in different weather conditions into the atmosphere of the pollutants in the atmosphere transmission dilute diffusion transformation and remove the rule and application of science. this subject originated from the 20xx s 20 years british atmospheric diffusion experiment was carried out but only in the '50 s the development of modern industry and city population is highly concentrated there appeared the serious urban or industrial pollution events in december 20 's london smog event for example took the lives of more than four thousand people these make people wide attention and research of atmospheric pollution to the 60 s then gradually formed this new independent discipline.

air pollution due to human activity or natural process and out into the atmosphere into some harmful substances (pollutants) when the amount of discharged into enough (pollutant concentration up to a limit) makes the original clean air quality to drop if this situation is maintained long enough will be to humans animals plants and the atmosphere cause harm and adverse effects of the atmospheric state known as air pollution. of air pollution has three elements: the concentration of pollution sources and pollutants harm to human and biological.

clean the atmosphere is one of the necessary conditions for the survival of humans in one person in five weeks no eating or five days without drinking water to be able to sustain life but not breathing air for more than 5 minutes then die the body to absorb every day 10-12 cubic meter of air. thus eliminating air pollution or keep pollution concentration falls below a certain limit is how important.

pollution sources and pollutants discharged into the source of harmful substances into the atmosphere pollution sources harmful substances into the atmosphere pollutants. atmospheric pollution source points of artificial and natural sources

the harm of air pollution and influence

atmospheric pollution on human and environment caused by the harm and influence has gradually been recognized in the aggregate has the following several aspects:

(1) the harm to human health. human suffering has three pollute the air surface skin contact with the air inhaled and eating food containing atmospheric pollutants besides can cause respiratory and lung diseases but also on the cardiovascular system liver etc serious can take away the life.

(2) the harm of biological. animals because of the inhaled air pollution or eat foods containing contaminants and disease or death atmospheric pollutants can make the plant disease resistance drop influence the growth leaf spot wither or die.

(3) the harm of items. such as the textile clothing leather metal products construction materials culture art etc. chemical damage and defiled damage.

(4) cause acidic precipitation such as agriculture forestry fresh water aquaculture.

(5) destroys the high-altitude ozone layer ozone hole formation cause harm to human and biological survival environment.

6. impact on the global climate such as the increase in carbon dioxide and other greenhouse gases will cause the earth's atmosphere warms lead to increased global weather disasters and aerosol particles such as smoke increase the atmospheric turbidity solar radiation affect the longwave radiation the earth may lead to abnormal weather climate.

how to prevention and control of atmospheric pollution reduce the harm of air pollution and influence constitute a major and urgent research subject. prevention and control of atmospheric pollution

prevention and control of atmospheric pollution is a huge system engineering need to be individual and collective national and the joint efforts of the world can consider to take measures in the following aspects:

(1) to reduce emissions. use more pollution-free energy (such as solar energy wind energy hydroelectric power) reform the energy structure with low pollution energy (such as natural gas) pretreatment of fuel (such as coal desulfurization) before such as improving combustion technology can reduce emissions. in addition before the pollutants into the atmosphere not use dust smoke abatement technology condensing technology liquid absorption technology recycling technology to eliminate some pollutants in the exhaust and can reduce the amount of pollutants into the atmosphere.

(2) to curb emissions and make full use of atmospheric self-purification ability. different meteorological conditions the capacity of the atmospheric pollutants into the same amount of pollutants the pollutant concentration was different. for wind good ventilation turbulence strong convection area and time atmospheric diffusion dilution ability is strong can accept more corporations to inversion region and time atmospheric diffusion dilution ability is weak cannot accept more pollutants otherwise it will cause serious air pollution. therefore respond to different regions different times for the effective control of emissions.

(3) site selection design of chimney urban and industrial planning should be reasonable don't emitters transition concentration repeated superposition don't cause pollution formation of local serious pollution incident.

(4) greening afforestation make more plants absorb pollutants reduce atmospheric pollution.

through the above explanation we know the importance of air for our human right from now on please protect the environment afforestation and create a better living environment!

today my speech is that under the flag of thank you.

核污染演讲稿篇4

众所周知，在我们生活的这个地球上，水资源正日益匮乏。

地球有将近四分之三的面积被水覆盖，但其中极大部分是咸水，只有0.2%左右的淡水能被人类利用。然而，在我们的日常生活中，人们对水资源的保护意识浅薄，水环境已经被我们严重污染。

海洋在无知的人类的全面侵入下，早已被严重污染。人类继续把在陆地上演练纯熟的老手段：“开发-掠夺-破坏”运用在了地球最后一块阵地——海洋。现在，美国每年排放入大海的污水超过200亿吨，排放入海的还有超过7000万吨工业废渣。日本排放入海的污水超过130亿吨，独联体每天有超过300万吨的污水排入波罗的海。中国每年也有100亿吨的污水排放入海洋，沿海有200多个排污口，昼夜不停的向大海排放污水，使沿海水域、渔场受到严重的污染。最近，渤海湾的`渔民沉重的发现：渤海竟然没有鱼了!

在这个星球上每年有2500万人因水污染而死亡，有10亿人喝不到干净的饮用水面对如此严重的问题，作为学生，我们应该做些什么呢?用洗过菜、水果的水来浇花，用洗过衣服的水来冲马桶等。这些办法都可以达到保护水资源不受污染的效果。我们还可以努力学习，在将来学好知识后，利用先进的科学技术，以低成本将咸水变为淡水，将受污染的水回收后进行处理并再次利用。

水是生命之源、发展之本。让我们节约每一滴水，珍惜每一滴水，保护每一滴水!

核污染演讲稿篇5

随哥本哈根气候大会的召开，“绿色”、“环保”这等词早已脍炙人口，深入人心，成为了全球关注的焦点。世界环保日，世界关灯一小时，新能源的开发和利用，似乎能源危机和环境污染已成为了世界人民心上的一支利剑，不知何时何地就会射发，危及人类的命运。但事实的确如此，这个孕育了我们祖先，创造无数奇葩的自然生态圈，缺了一处两处，便会像多米诺骨牌一样，一触便不可收拾。

于是有了绿色环保的活动，有的人参与是为了缓解自己对于“20xx”的恐惧感，有的人因此而成为“环保达人”，追名逐利，当然，也有人并且是大部分积极地保护自然，拥有了一颗绿色健康的心灵。且不论这等人的孰是孰非，作为一名高中生，在全球的环保热中，我们又该扮演何种角色?又该从哪方面入手?

人们常说，从小事入手，从点滴开始，于是让我们看看一张纸巾的蝴蝶效应……

洗完手，一张纸巾在手，用过便丢了;抑或擦了一滴墨水，就把一张三层的至今蹂躏完后扔向纸篓;更有甚者闲来无趣便撕个纸条玩，这种情状发生在我们随性潇洒的90后身上仿佛是与生俱来般的自然。但一张纸的'价值不仅在此，若每个人都能节省一张纸，结果可是完全不同的。

一棵10年树龄的树可以制成20xx张纸巾。那么以中国为例，13亿人口每个人节省一张纸巾，那么，将会有约650000棵树免遭砍伐。而每一棵树每天吸收的二氧化碳量大约为5023克，一年就有将近1.83吨，每天放出的氧气有约3653克，一年就有将近1.3吨的氧气被放出，每吨的价值在31250美元左右。650000棵树，一年就有1190000吨的二氧化碳被吸收，价值26400000000美元的845000吨氧气被生产出来。

没错，千万别怀疑，这就是节省一张纸的事情。

因此，无论事大事小，环保自在人心。

就如我们学校此次的国庆通宵，在班级布置方面，学校力求节俭创新，于是，在资金限制和时间有限的双重压力下，我们拿出了上次通宵活动用来布置教室的物品，裁裁剪剪拼拼，俨然又成了另一新物。创新有了，节俭也有了，可谓双赢。就这样，当被同学问及班级布置材料来源时，我会心一笑“都是去年的”。“全部都是?”“恩，全部都是”同学惊讶的表情业已说明了一次环保活动在无形中生成了。
