篇1：全球变暖的演讲 环保的演讲稿800字
朋友们：
读过美国著名作家欧·亨利小说《最后一片叶子》的人，想必还记得这句话：“当最后一片叶子落下时，生命就都结束了，我也得离开这个世界而去了……”。酷爱生活的女画家约翰西，患了肺炎濒临大限时，“害怕在她轻轻抓着这个世界的手越来越乏力的时候，她会真的像一片轻轻的、纤弱的叶子那样，随深秋的寒凤飘逝而去”。初读这篇小说时，少年不识愁滋味，对主人公那仿佛病态的痴语我并不以为然，而正是在人类对绿色顶礼膜拜，绿色食品，绿色能源、绿色电脑、绿色冰箱，绿色建筑被人们广为崇尚的今天，重读小说《最后一片叶子》，才感悟到，这分明是一个寓言故事，约翰西的心语，分明是谷世之言，大籁希声。
就在欧·亨利自己的国家美利坚合众国的土地上，不是就有过深刻的历史教训吗?著名总统罗斯福对梅花鹿可谓情有独钟，从这点小小的总统私人利益出发，他便下令对北利亚桑纳州一片茂密的大森林进行大规模扫荡，大批鹿的天敌——狮子、狼等食肉动物被捕杀殆尽。四千多只鹿于是生物爆炸一般，呈几何级数迅猛增长，十几万只伸特长脖子的可爱精灵们，吃光了树上的叶子，仿佛只在转眼问，著名的大森林就从地球上消失了，最后剩下的，只有凡头病鹿。 鲁迅先生说过，悲剧是把美好的东西毁灭给人看。
在我省南部，有一个美丽的地方，她向来就被人们称为镶嵌在我们这个植物王国皇冠上的一颗绿宝石。她的美丽，当然是绿色赋予的。可是，就在这绿宝石之上，有8家红砖厂的大烟囱，不分昼夜地喷吐着氟化物和二氧化硫严重超标的浓烟，致使1262亩的天然橡胶林受害，三万零五百株橡胶树为之枯死，胶民们虽然怨气沸腾，却眼睁睁地奈何不了它，无独有偶，在同一纬度的广西某地，也上演过惊人相似的一幕，如果说那一幕还有点不同的话，就是红砖厂的废气除了使大面积胶林枯死外，还造成50多亩芒果只开花不结果，出现果荒。我们知道，天然橡胶是目前地球上极为少有的自然资源，仅生长在赤过附近，我们也知道，芒果是公认的“水果之王”，那么何以会出现上面那样的情况呢?——因为红泥巴变成砖块，只需要几天的时间，远比橡胶芒果来钱要快!
绿色是和平和生命的象征。在很小的时候，我的心便融进了一个绿色的海洋。穿了十凡年国防绿的我，在老山战区那片阳光充足，绿色位浓的亚热带丛林中，度过了人生位美好的一段年华。就是在那样一个空气、阳光、风雨充足的天然大氧吧里，我步入了而立之年。此生最难忘的，能维系裁生命的，大概就只有那特殊的一片绿色了。而事实上，那片我魂牵梦紫的土地至今还不富裕，一些地方生产力水平低下，社会发育程度不高，边民的农事，至今还离不开刀耕火种，纵火烧荒。我曾目赌过两个边民合伙买一盒火柴平分的事，开始想当然地以为他们太穷，买不起一盒囫囵的火柴，后来才发现，在他们的生活里，四季灶膛火不断，一根火柴烧一年，大树小树变成灰。我能给他们的，就是一个毫无用处的忠告：可别把咱的林子都烧光了呀。
人类只有一个地球，我们对这个星球上的生态系统有着永远摆脱不究的依赖性，需要地球源源不断地提供植物和动物的食物，需要有足够厚度的大气层，来保护人类不受过高成过低气温，以及过量紫外线的伤害，需要地球提供足够量的水和氧气来维持生命的存在，而没有了绿色，这一切岂不成了无本之源，好比毛长在皮子上，没有了皮，毛又咋生根?
聪明的作家欧·亨利是以其“欧·亨利式的结尾”著称于世的，那最后一片不凋的叶子，带来的是一个危亡病人的新生。我想，我们也会创造出另一个欧·享利式的结尾，迎来人类新生的。坐以待毙，从来就不是人类的选择，人类既已觉臣，就会在危机面前积极行动起来，把握历史机遇，化压力为动力，保卫绿色，保护我们共有的家圈。

Global Warming
There is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were , , , , .
The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.
So now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?
The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.
Firstly, plant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.
Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?
When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.
If possible, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.
Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.
If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity.
Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.
Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.
If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to do your part. After all, it will be our next generation that will feel the effects.

However hard the situation is, we shouldn't lose our heart, because we haveour dreams. Our dreams are always glorious. We also have enthusiasm that willmake our dreams come true. But we must have the willingness to workhard, since if we work hard, some miracles will happen. Nothing goodwill happen without our hard work.What's more, when we are unhappy, we can thinkabout our dreams, so that we will be more enthusiastic. When we are defeated, weshould stand up and say,“ I'm not a failure.” Please remember, “ Anything ispossible to a man who has a strong determination.”
篇6：全球变暖的英语演讲稿
I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.
First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new “hobby”, but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.
Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic China's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.
More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs “of the south-north water diversion project”.
In order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!
篇7：全球变暖的英语演讲稿
People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.
The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.
To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.

篇9：3分钟关于全球变暖的英语演讲稿
In recent years do you think the weather suddenly turned hot had the cool autumn now almost until early October the hottest day in August has reached more than 40 degrees. These is different from normal vision we have ourselves to blame the curse.
Today the term “global warming” has gradually penetrated into our life. The word sounds very academic even feel very far away from us so some people are not. In fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels and so on. Both harm the natural ecosystem balance more threatening human food supply and living environment.
Now that you have aware of the dangers of global warming you should go to predict and improve it. Imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms the next round of searing heat the next major natural disasters will happen? China? The United States? Japan? No one knows. The debate has ended. Scientists around the world agree points out that the earth's average temperature has increased nearly 1 ℃. Due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. Scientists will have the most advanced computer data input model to estimate the earth can face the future. Prediction results are worrying. Forty years later the Himalayan glaciers the water to the survival of millions of people are likely to disappear. The Greenland ice sheet could melt in 50 years. Currently half of the world's biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land by the end of the century. Is likely to be the future of the world like in the movie “the day after tomorrow” tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption... This is not a crazy fantasy if humans don't stop destroying the environment it will become a reality!
However in the warming is also good. Global warming on rice in heilongjiang province has played a large role.
Just global warming to human future development is still the do more harm than good.
In order to save the planet we should try to be: don't open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide don't use plastic bags R22 by bus; R22; Little drops of life. Actually it's not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.
Thank you all!
篇10：3分钟关于全球变暖的英语演讲稿
Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.
The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.
Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.
Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.
Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.
In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

篇12：3分钟关于全球变暖的英语演讲稿
The topic of global warming is attracting the attentions of countries all over the world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make large sections of the earth uninhabitable.
What have caused global warming? The theory and evidence strongly suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.
How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so. A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A further recommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions.
China is the rising economic star; and if it also wants to assert world leadership status, it is a good opportunity for China to show the world that it has a moral commitment and the will to fight global warming.

篇13：环保演讲稿800字
尊敬的老师，亲爱的同学们：
大家上午好!
我们住在地球上，因为她是我们唯一能住的地方。没有阳光、植物、氧气和开水，我们就无法生存。绿色是大自然赋予我们的宝贵财富，是人类文明的摇篮。每个人都渴望有一个美丽的家，每个人都想生活在一个人与自然和谐发展的文明环境中。
近年来，随着“建设卫生城市”的号召，我们的校园环境正在发生全面的变化。校园环境建设是我们必须直接面对的问题。校园绿化的程度直接影响着我们的生活环境，决定着校园生活的多少色彩。当然，绿色校园不仅仅是一个环境绿化和垃圾处理的问题，它的含义应该更广更深，指的是一种健康向上的态度和生活方式，比如认真活泼的学习氛围和积极向上的班级精神。创建绿色校园，不仅要有优美的硬件环境，还要提高自身修养和素质，这也是我们的责任和义务。每个人都是保护绿色的天使。
我们应该使用绿色 色的实际行动去影响周围的人。我们更应该保护校园环境，共建绿色校园。为了共创绿色校园，我们同要携起手来。让我们共同做到如下几点： 1、立即行动起来，关心、支持和爱护绿化，积极参与校园绿化建设和管理，从小事做起，从一点一滴做起，从身边做起; 2、爱护花草树木设施，对破坏绿化设施的行为要敢于制止并举报。 3、养成良好卫生习惯，不随意乱扔瓜皮果壳、烟头，不随地吐痰。 4、不使用污染环境浪费资源的产品，特别是不使用一次性碗筷和少使用塑料袋; 5、树立和倡导绿色文明意识，积极参加校园爱绿护绿行动; 6、勤俭节约，节约校园内的各种资源，随手关好水龙头和电灯电扇，节约每度电，节约每滴水; 7、师生和谐，同学之间友好相处，语言文明，行为规范。 8、一切都以更高的目标束缚要求自己，将自己培养为有文明素质，全面发展的优秀中学生。
同学们，我们是21世纪的主人，我们要增强我们的环保意识。我们应当有时代责任感。“勿以善小而不为，勿以恶小而为之”，共建绿色家园，共同保护地球母亲，让我们行动起来，共创我们的美好家园!
篇14：环保演讲稿800字
尊敬的老师，亲爱的同学们：
大家上午好!
今天我演讲的题目是：加强环保意识，维护班级环境。我们经常看到许多同学在校园里的各个角落捡拾果皮纸屑;用自己的双手去保护校园环境的优美。但是，我们仍然存在着一些不足：仍然有人乱丢纸屑、食品袋废弃物;仍然有人在草坪上肆意践踏;学校的绿化带中，不时发现有深深的脚印、有的地方甚至走成了小道。
我想给大家讲个故事：有一个傍山依水的村庄，村庄附近有一片广袤的森林，森林里什么动物都有。居民们以务农为生，他们和动物和平共处。有一天，一个城里人误入农庄，他在附近遛跶几回，连呼可惜：“拥有如此得天独厚的金矿，你们怎么不知道开发致富呀?”“我们有金矿?在哪?”“你们不知道，这里有的是发财的东西。就说这里的树吧，就价值连城。城里人对木头的需求量很大，很多生活用品都要用到木头。现在城里木头紧缺，你们这里什么都缺，就是木头不缺。你们把树砍下来，加工成木头，不就可以换来大把的钞票吗?再比如，你们把森林里的动物都抓住，皮毛剥下来做成名贵的衣服，肉制成野味，高价出售。总之没个部位都可以变成钱!”对呀，他们怎么没想到呀?这样的钱太好赚了!于是，全村的居民们开始了“致富”的道路……没过多久，方圆千里的树全被砍光，动物也无一幸免。当然农民都过上了幸福的日子。可没过多久，不幸就降临了，一会儿旱，一会儿涝，再也没有风调雨顺的时候，庄稼根本没收成，可吃的东西渐渐也找不到了，全村的人都死了。方圆万里，既无人烟，也看不到任何生命的痕迹，宇宙一片死寂。我总在想：这个世界如果没有鸟语花香，没有飞禽走兽，没有茂密的森林、清澈的江水，只有自私野蛮的人类，那将是多么可怕!
同学们，我们是21世纪的主人，环保意识是现代人的重要标志。我们应当切实地树立起时代责任感。心系全球，着眼身边，立足校园。多弯弯腰捡捡果皮纸屑，首先是不要随地乱扔乱丢;多走几步，不要穿越绿化带，践踏绿地。“勿以善小而不为，勿以恶小而为之”，从我做起，从小做起，从身边做起，从现在做起。保护地球母亲，净化绿色校园。让我们的校园更加美丽吧! 我的发言完毕，谢谢!
篇15：环保演讲稿800字作文
生活在科技发达的21世纪，每个人都知道保护环境的重要性。虽然每个人都知道要保护环境，但是很少有人能真正做到“保护环境，人人有责”！
当我们看到臭气熏天的小河，一片光秃秃的树桩，弥漫着沙尘暴的城市时，我们是否有所悔悟？虽然这些现象还没有出现，但是我想：人类如果在这样肆意妄为下去，必将自食其果！
水是生命之源，万物生存都需要水，人类也不例外，如果没有水，人类将濒临灭绝。古人以为水是上天恩赐的，取之不尽，用之不竭，其实并非如此，全球的淡水资源只有35.5亿立方米，在这有限的淡水资源中仅有0.34%的水可以应用。这么珍贵的水资源，人类不仅没有好好节约，反而大面积的浪费。我听到过这么一则新闻：有一些不法商家为了方便把本该自己能处理好的污水大量排入河道，污染了原本干干净净的河水。生活中，这样的事情不断地在发生：酒店的工人把要洗的菜放到水池中，拧开水龙头，便转身离去，任凭那自来水“哗哗”地流。过了好长一段时间他才回来，把菜拿走，临走时竟没关水龙头！大量的生活用水流入排水管道，造成了极大的浪费。有些居民为图方便，在小河中洗衣服、洗碗、洗拖把，久而久之，小河里飘满了垃圾和油渍。
我们要节约用水，绝不能让我们后悔的眼泪成为世界上的最后一滴水！
地球陆地的四分之一是森林，丰富的森林能给我们提供新鲜的空气和充足的水资源，但是，有这么一个报告：再过一百年森林将彻底消失。也许我们活不到那时，但我们不得不考虑我们的子子孙孙。想象一下森林消失的那一刻，世界上各种生物都灭绝啦，地球上死气沉沉，那多可怕！
也许你会想：森林消失管我什么事，它消失不会影响我们。不！森林肩负着重大责任。他能控制水土流失并防止自然灾害。如果森林消失，各种自然灾害就会接二连三地向我们袭来。就算我们在灾难中没死，自然灾害也会毁了我们的家园！
保护环境不止是我所说的这些，我们要从生活中做起，我们要从小事做起，从你我做起！
篇16：环保演讲稿800字作文
相信很多人一定听说过“地球一小时”熄灯活动，3月31日，雷锋塔下一场难忘的篝火晚会异常美丽，蜡烛摆成“60”字样象征着这美妙的一小时，今年“地球一小时”的活动主题是：每个人心中都有位环保家。
我们曾经这样自豪地歌颂过我们的祖国：地大物博，山河壮丽！大家知道，我国是当今世界上最大的发展中国家，人口数量极为庞大。温家宝总理曾提出了这样寓意深刻的乘除法：“多么小的问题，乘以13亿，都会变得很大，多么大的经济总量，除以13亿，都会变得很小。”举个例子，我国淡水总量为28000亿立方米，这本来就不富有，除以13亿之后，人均淡水资源更是只有2200立方米，仅为世界平均水平的四分之一！生机勃勃的森林是非常富饶的，有“地球之肺”的美誉，但是我国的人均森林面积位于世界120位之后，而现在更是以每年1800万公顷以上的速度急剧减少。森林的减少，使得气候变坏，水土流失严重。原先被誉为中华母亲河的黄河变成了一个十足的“暴脾气”。
老师们，同学们，面对日益恶化的环境，为了人类的可持续发展，为了美丽的地球家园，我们该做些什么呢？
我们要节约每一滴水。记得随手关好水龙头，不要以为水笼头滴几滴水算不了什么，一个水笼头每秒钟滴一滴水，一年就是白白流掉36方水。我们要积极寻找生活中节水的“金点子”：比如把洗菜的水用来浇花、涮拖把、冲厕所等等，加以循环利用。
我们要节约每一度电。随手关灯，合理使用空调，寻找节电小常识，并尝试着去实践。积极使用太阳能、风力发电、潮汐发电等清洁能源。我们要节约每一张纸。要做到作业纸双面使用，多用手帕，少用纸巾。假如我们每人每天节约一张纸，全国一年可以节约4745亿张纸，一年可以少砍伐158。1666万棵树。从这个意义上来说，节约用纸，也就是制造森林。
我们要倡导绿色出行。汽车排放的尾气中含有大量的二氧化碳，会使地球产生“温室效应”。少开一天汽车，多骑一天自行车，既能使空气更清新，又能使我们的身体得到锻炼。
我们要推广使用环保袋。因为塑料袋的焚烧会产生很多的毒气，污染大气，而且不容易降解，会破坏我们的土地，所以我们要尽量减少“白色污染”。
节约资源、保护环境，需要每一个人的力量，同学们，让我们行动起来，做一名节约资源，珍爱地球的环保小卫士！
篇17：环保演讲稿800字作文
放眼望去，有的只是凹凸的地皮，大片大片的树林遭人砍伐，变成人们生活上的木制品。人们只为一己私利，使成群的动物流离失所，奔向它方。这并不是虚假的幻想，这是血淋淋的事实。
曾几何时，世界上大批的动植物遭到灭绝，还有许许多多的动植物濒临灭绝，这都是为什么？这都是因为人类乱伐树木，破坏了生态环境，这才是根本原因。
土地资源是三大地质资源（矿产资源、水资源、土地资源）之一，是人类生产活动最基本的资源和劳动对象。人类对土地的利用程度反映了人类文明的发展，但同时也造成对土地资源的直接破坏，这主要表现为不合理垦植引起的水土流失、土地沙漠化、土地次生盐碱化及土壤污染等，而其中水土流失尤为严重，乃当今世界面临的又一个严重危机。据估计，世界耕地的表土流失量约为230亿吨／年。
有人认为酸雨是一场无声无息的危机，而且是有史以来冲击我们最严重的环境威胁，是一个看不见的敌人。这并非危言耸听。随着工业化和能源消费增多，酸性排放物也日益增多，它们进入空气中，经过一系列作用就形成了酸雨。
赤潮虽然自古就有，但随着工农业生产的迅速发展，水体污染日益加重，赤潮也日趋严重。我国自1933年首次报道以来，至1994年共有194次较大规模的赤潮，其中60年代以前只有4次，1990年后则有157起。石油类污染对水质和水生生物有相当大的危害。漂浮在水面上的油类可迅速扩散，形成油膜，阻碍水面与空气接触，使水中溶解氧减少。油类含有多环芳烃致癌物质，可经水生生物富集后危害人体健康。二氧化硫主要由燃煤及燃料油等含硫物质燃烧产生，其次是来自自然界，如火山爆发、森林起火等产生。二氧化硫对人体的结膜和上呼吸道粘膜有强烈刺激性，可损伤呼吸器管可致支气管炎、肺炎，甚至肺水肿呼吸麻痹。短期接触二氧化硫浓度为0.5毫克／立方米空气的老年或慢性病人死亡率增高，浓度高于0.25毫克／立方米，可使呼吸道疾病患者病情恶化。长期接触浓度为0.1毫克／立方米空气的人群呼吸系统病症增加。另外，二氧化硫对金属材料、房屋建筑、棉纺化纤织品、皮革纸张等制品容易引起腐蚀，剥落、褪色而损坏。还可使植物叶片变黄甚至枯死。
保护环境，人人有责。
篇18：关于环保的演讲稿800字
昔日的春天报春的燕子往来逡巡，空中充满了他们呢喃的繁音。夏天苍翠欲滴的盛装郁郁葱葱充满生机。秋天，红艳艳的苹果扒开绿叶往外瞧，小红灯笼似的枣子挂满了枝头，像紫玛瑙的葡萄一串串地挂在葡萄架下冬天，鹅毛般的大雪飘飘柔柔的落了下来，如柳絮一样。
而现在由于我们的影响，尤其是人们乱伐森林、滥垦草原，以及环境污染，造成了野生动植物栖息地或生长地的丧失和生活环境的恶化，再加上人们滥捕滥猎野生动物，使世界上许多种野生动植物已经灭绝或濒临灭绝。那些优美的景色也随之消失了！
地球上日益枯竭的资源，例如：水、汽油、树木……保护这些是我们生存发展的最起码条件。当工业进入20世纪后，工厂对环境的破坏日趋严重，对资源的使用走向了滥用，这引起了人们越来越高度的警惕。今天，提起环境保护，几乎没有什么人会公开反对，但是真正做到自觉长久地保护环境，保护资源，还有许多资源在等待着我们去保护。
环保是现代生活中人类面临的最大问题。要解决这一问题必须从基础做起。首先，要大量宣传，提高人们的觉悟与认识，加强环保意识。就是要在全民族树立起环保意识，具体地说就是树立资源意识，生存意识，让他们知道不环保的危害。还要让大家都认识到，保护环境与资源和我们每个人息息相关，要以少成多。保护环境不仅是关乎子孙后代的生存，而且已经直接关系到人类社会今天的存亡！不能抱着环保多我一人少我一人差别不大的思想，也不能对保护环境有任何松懈和怕麻烦的思想。其次，要进行废物回收利用，减少对森林树木的砍伐。还要加强对白色污染的处理，少使用塑料制品最后，要对清洁方面作改进。使市容更整洁。为了地球的明天，我们必须从现在开始努力，要好好地保护环境。于此我们提出如下建议：实行垃圾分类袋装化。这样不仅能减少环卫工人的工作量，还能更好地起到废物利用，减少污染，节约资源。买菜时，少用塑料袋，尽量用竹篮子。用笔尽量用可换芯的，减少圆珠笔外壳的浪费与垃圾量。外出吃饭尽量不用一次性饭盒。
只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、为地球、也为自己留下一片碧水蓝天。
篇19：关于环保的演讲稿800字
尊敬的老师，亲爱的同学们：
大家好!
崇明岛，被亲切地称为上海的后花园，这座后花园地处北亚热带，气候温和湿润，日照充足，雨水充沛，四季分明。它每一八都是生机盎然，充满了欢声笑的。我爱它，我爱在蓝天白云下享受云融融、风淡淡、水盈盈的大自然心情。然而，忽然有一天，正当我们全身心投入它美丽的怀抱中时，它却被一种外来植物伤害着，毁坏着……
曾经的中国饱经风霜，被许多国家肆意践踏、侵略，虽然这种时代早已一去不复返，可是却有着另一种同样强大的敌人在进行历史重演，那么如此热爱宝岛的我们却又如何忍心让它再次罹难?!
这种具有极强生命力的植物，便是现在常见的加拿大一枝黄花。它最初是作为庭园花卉引入上海的，的确初看它们，是一片绚烂夺目的黄色，它使我们的双眸享受到一幅浑然天成的美景，让我们忘情地欣赏、赞扬它。然而殊不知，就在这美丽外表的掩藏下，它有着危险的“使命”——破坏、阻碍其他农作物、绿化草坪的生长，甚至是无情的扼杀它们。
加拿大一枝黄花的出现，使栽种的绿化灌木成片死亡，使公共绿化地带的草坪遭到破坏，便农民辛苦耕种的农作物减产……它实在有着太多太多的不是，实在是像一个无形的杀手在肆无忌惮地疯狂游戏着，伤害着我们美丽的宝岛。
因此，我们必须尽每一份力量来保护好我们的家园，彻底消除一枝黄花。相信，在我们每个人全身心地努力下，在不久的将来便会剔除这片危险的黄色地带， 迎来另一片更健康、更美丽的绿色，使宝岛比以前更美、更五彩缓纷。
21世纪，是绿色的世纪。崇明岛的大开发和生态岛的建设与我们每一个学生、每一所学校都是息息相关的，所以作为一名学生的我就应该大力宣传建设生态家园的重要性，全面提高防止生物入侵和保护生态环境意识、树立正确的环境价值和生态文明观，负起环境责任，促进社会、经济和生态的可持续发展。现在我们的学校越来越注重校园环境和校园绿色文化建设，我们努力、积极地开展各种环保活动，为莘莘学子营造更好地学习氛围。如果你在我们的学校中任意地转上一圈，你就会发现到处都有绿色和鲜花。我想，这时你的心情一定是好到了极点吧!尤其在夏季，花坛中的各类花卉争相怒放，争奇斗艳，更引来蝴蝶留恋忘返，路过时，常常能看到它们在尽情飞舞，喧闹着，为我们的平凡校园生活增添了许多乐趣、许多生机!
篇20：践行环保800字演讲稿
尊敬的老师、亲爱的同学们：
大家早上好!今天我演讲的题目是《坚定信念日行一善》。慈善就在身边，就在眼前，就在一转念间，就在举手投足中，慈善不应该是富人良心发现时的施舍和恩赐，而应该是每个人从内心深处发出的对他人的同情与关爱。我们没有钱，没有势，并不说明就没有帮助别人的能力，俗话说：千里送鹅毛，礼轻情谊重。慈善事业的最终目的不在于给予了多少，而在于有没有一颗同情和善良的心。
记得去年9月1日来到历城职专的第一天老师叫我们做一份日行一善登记本，我心里非常抵触，心想：老师让记录日行一善，我胡写乱写不就可以糊弄了吗?因为我真的想不出有什么善事可做。所以就偷偷的胡写一通，应付过去，知道一周后被老师发现不真实的记录，没行善却把自己写的特别高尚、伟大，不是自己做的好事或者自己做不了的好事也写上了。同学们你们知道吗?当时我羞愧极了，我没有明白学校开展日行一善的活动的真正目的，没有懂得日行一善的真谛。
老师说做善事的终极目标是让我成为一个善良的人，为了净化我的心灵，让我们的心干干净净，从心里散发美，让别人以为遇到我而感到幸福，用我的行为影响别人，对，我要做个善良的人。
日行一善应该怎么做?
比如：捡起脚下别人扔的纸片，扔到垃圾箱里去。这就是善的行为，比如向与你擦身而过的人微笑。卫生扫除过程中你帮我我帮你的行为，背后不说别人的坏话这也是善的行为，所以行善不分大小事。我记得5月25号开学那天，我们学校的志愿者站在马路两边，帮助同学搬运行李，这就是做善事，我的爸爸妈妈就说：你们学校的孩子真懂事。这一天是我非常感动和自豪的一天，我们学校同学得到了家长的肯定，只要我们坚持下去，我们还会得到更多人的肯定。
再比如公交车上让座也是善的行为，那我们能不能够做到?当我们看到老人和小孩我们能不能让座呢?此时这个问题我问到了同学们心坎里，让座和不让座就在一念之间，就在我们纠结让不让的瞬间，就在善和恶斗争的瞬间。我从今天开始一定让座，让行善成为我的好习惯，从每天捡起一片垃圾开始，从公交车让座开始，从把被子叠整齐开始，从日行一善，养成习惯;我行善，我快乐!有了善，校园才会有和谐!社会才会和谐!世界才会和谐!
我的演讲到此结束，谢谢大家!
