Ladies and gentlemen,
I am honored to stand here to share with you on such a important subject as climate ,it is global warming .
Let me give you two phenomenons.
Here is the first one. More and more people used to be using air condition ，but how many people ever thought whether this new ,hobby will bring side-effects or not? Maybe just few people. In fact, the side-effect is apparent. The emissions of gases exhausted from air conditioning contain a lot of methane h could cause global warming. By the way, air conditioning will waste a lot of electricity .
The second one is about the increasing amount of cars. According to the statistics, in 21st century, there are 7 millions cars in the world, a large amount of exhaust gases has seriously influenced us, such as: cough, throat inflammation.
This two phenomenons are just few part of reason which change our environment badly. There are many other reasons.
In nearly 100 years, the average global temperature experienced twice fluctuations which is “cold-warm-cold-warm”. Generally, it is the trend that global climate is becoming warmer and warmer . In 1980s,global temperature rised apparently. According to Chinese scientists, the average temperature in China has risen by 1.1 degrees
Stepping into the new century environment pollution has become more serious than ever since. There are different kinds of pollution. Such as water pollution air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. where all these pollution comes from? To a large extend the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street the gas stations are short of gasoline even the government has raise the price so many times in order to control the needs of gasoline but it’s still not working. Overusing the natural resources has already affected the ecological balance. However the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.
The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way our earth could be a better place to live in.
In recent years there has been a marked growth of fire accidents in big cities of our country. Almost every day we see fire engines rushing through the streets. Fires have not only resulted in heavy economic losses but also injured and killed many people.
What are the causes of fire accidents? Most of the fires are brought about by carelessness and violation of fire safety regulations. Others are due to the poor quality of home electrical appliances. By the way, some people don't know how to use them properly. Besides,there are quite a few businesses which focus so much of their attention on profits that they tend to neglect and even ignore fire precautions.
In my opinion, in order to prevent fires we should first of all foster people's sense of fire prevention. The second thing we have to do is to increase the number of professional fire fighters, to whom regular training courses should be offered. Finally, we are to improve the existing fire engines and add more fire facilities to high-rise buildings. In this way, a reliable fire prevention system will be formed.
protect the environment.
Good environment can make people feel happy and fit . To improve the environment means to improve our life.
We should plant more trees and flowers around us . We shouldn’t cut them down . We should stop factories from pouring waste water into the river and waste gas into the air.
Whenever we see litter on the ground , we should pick it up and throw it into dusbins. Never spit in public. Don’t draw on public walls. It’s our duty to protect the environment.
The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.
Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that can't be replaced. Too much fishing may harm fish populations to the point where they can't recover. We are too careless in taking what we want without giving anything back.
There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners can't keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.
With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If we're not careful, we can harm our planet beyond repair.
People need to respect the Earth and try to preserve it. If we don't, what kind of future will we have?
Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution. Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
protect the environment?
Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so it causes many problems like the Greenhouse they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the we can start from now to make a beautiful life.
We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.
Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one.
Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big problem.
尊敬的老師，親愛的同學們：
大家好!今天是6月5日—世界環保日。今天我要演講的題目是《保護環境衞生，人人有責》。
在我們的日常生活中，生活環境是十分重要的，但人們常常不重視這一方面。使清澈見底的小溪變成了骯髒的水溝;鬱鬱葱葱的大森林變成了落光頭髮的老爺爺;鳥語花香的村莊變成了山洪爆發的地方……這一切都是由人類的一舉一動所造成的。
前幾日，我到廣場上騎自行車，發現不遠處的草坪中有許多的白色垃圾，真是不計其數!可見我們的環保意識還不夠強。説小一點兒，影響該地區的形象;説大一點兒，這是影響我們國家的形象啊!
作為一名少先隊員，作為一名小學生，我們也應該保護環境，從我做起，從小事做起，從力所能及的事情做起。當別人隨手扔下垃圾的時候，你會去撿起;當別人踐踏草坪的時候，你會去阻止;當別人在破壞樹木的時候，你會去教育……
曲格平曾經説過：“沒有一個清潔美好的環境，在優裕的條件也毫無意義。”南丁格爾也曾説過：“人生欲求安全，當有五要：一要清潔空氣;二要澄澈飲水;三要流通溝渠;四要掃灑房屋;五要日光充足。”我相信，在我們的共同努力下，我們的家園一定會成為一個美麗、健康、幸福、和諧的世界!
讓我們從小事做起，從我做起，愛護花草樹木，愛護環境，讓明天的世界變得更加美好!
謝謝大家!
同學們：
大家好!
今天我要演講的題目是保護環境。
保護環境是每個人的責任，社會無論如何發展，人類都得承認一件事實，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。
可是，人類像一個貪婪的孩子，只顧索要，不管回報，以至於現在的環境傷痕累累，場次以來，受傷的必將是我們人類自己……
瞧!如果不保護環境，大自然母親也將會發怒，比如20xx年的5。12大地震，日本大地震，泥石流災害等，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罰嗎?
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，小花被採摘，難道他們不痛，不傷心嗎?亂砍濫伐，無節制的開採礦產資源。人們就是這樣，無所事事的破壞生態平衡。作為國小生，我們應該從身邊做起，從小事做起;保護花草樹木，不亂丟垃圾，不使用一次性筷子，儘自己一份微薄之力。
在此我呼籲大家;請保護環境，只有這樣才是最終保護了人類自己!因為地球只有一個，人類不能克隆。
我的演講到此結束謝謝大家!
尊敬的領導、同志們：
大家好!
當前人類社會已經進入十分發達的工業文明時代了，人類在不斷的進步，我們人類已經征服了地球，成為地球上的主宰，現在人類又開始征服太空，希望能夠在太空中找到自己更好的歸宿。殊不知，我們的地球已經被我們人類破壞的不能再破壞了，保護環境已經不是一時間的事情了，需要全世界人民的一起努力，我們的地球才會回到曾經的樣子。
其實，真的説不清是從哪一天開始，純淨遼闊的大海里產生了星球史上最早的生命精結綠藻羣帶;其實，真的説不清是從哪一天開始，奔騰不止的黃河岸邊出現了現代人銘記的祖先藍田人類;其實，真不説清是從哪一天開始，大地欣然地托起了普羅米修斯竊取的火種，從而宣告了文明初始而完整的誕生;其實，真的説不清是從哪一天開始，人類不僅征服了自然，而且開始學會向自然索取曾飽受天災的賠償資源潛能。
於是，人類的文明史上有了結實的木椅、精刻的木閣;而孕育出人類的原始叢林卻在傷心地萎縮;於是，人類的文明史上有煤炭、石油、地熱;而承接着人們瘋狂攫取的大地卻在悄悄地下沉、裂變、陷落;於是，人類文明史上有了林立的廠房、煙囱、化工車間;而那片曾經
温柔的晴空，卻正在被黑的、黃的、灰的污染殺手將臭氧層殘忍地撕破。
終於，人類的文明史上有了微觀得可怕的氫能、中子能、原子能，而從此，文明之邦的土地上不知多少因親離友散而痛苦淒厲的哭聲。
假如，歷史真的是一張翔實無疏的時間表，我只想查一查人類究竟是從什麼時候起開始學會把作為星球上的最高智能生物的特權發揮得如此淋漓盡致，卻輕而易舉地忘記，自然一樣會再次懲罰我們。
因為英國人無規劃地擴大工廠，排放廢氣;於是大自然便在1873年、1883年、1892年發生了三次倫敦毒霧事件侵吞一千八百人作為賠償。因為日本人在足尾銅礦瘋狂採挖，任排污水，於是大自然便讓400平方公里的良田變為荒園以示懲罰。因為美國人在狹長的平原地帶連建了鐵、硫、銅三大工廠，於是大自然便在1948年10月27日用毒霧遮籠整個山谷作為報復。 因為蘇聯人肆意將粉塵毒氣排入空中，於是大自然便讓加里寧格勒普降黑雪，讓1960年兩次黑風暴席捲俄羅斯大平原作為警告。因我們過分索取森林，於是大自然便以黃河兩岸土流失區達百分之七十四，一次性水災毀壞千萬畝沃土作為代價。
然而，人類不知為何卻固執地拋開了這些暗示，仍在一天天、一年年執迷不悔地犯着同一種錯誤，重演着同一種悲劇;終於，1952年一次倫敦毒霧事件死亡一萬兩千餘人是前三次總和的十倍;美國河谷帶十年肺氣腫死亡率上升為以前的百分之六百三十;蘇聯僅水污染一項每年損失六十億美元，這些加速上升的數字已迫使人類不得不承認，曾被征服的自然現在卻無法控制，中東北非的富饒土地變成極目無邊的沙漠;墨西哥的豐足糧倉變成了荒蕪的侵蝕斜坡;我國涼山彝族自治州的青山綠水被泥石流淹沒。
正如恩格斯指出的：我們不要過分陶醉於我們對自然界的勝利，對於每一次這樣的勝利，自然界都報復了我們。每一次勝利在第一步確定取得了我們預期的結果，但第二步、第三步卻有了完全不同，出乎意料的影響，常常把第一步結果取消了。
我們常常是在有意與無意之間，把地球推向了生命的底線。讓地獄迸爆出的烈火肆意侵舐着每一點綠色，讓所有的生靈在灼傷的苦痛中哀歎。
我們經常是在有意與無意之間，打開了潘多拉的魔盒，然後面對因貪婪的慾念鑄下的過錯，無奈地看着盒中升起的猙獰的黑煙在大地與天空間瀰漫。
我們常常是在有意與無意之間，撞響了天王手中的金玉琵琶，然後忍受綿延的噪音，卻不知該怎樣辦。我們常常是在有意與無意之間，使海面漂浮的石油粘住了海鷗的翅膀;使果林裏的農藥殘害了弱小的生靈;使夜空裏再也看不見清亮的星星，使明淨的湖水變成了一點就着的油坑。
我無以否認，人類正在夜以繼日創造文明;可是朋友，你能否認人類正在夜以繼日地毀滅文明嗎?
我們只有這麼一個美麗的星球，我們的先人和我們的後人都註定要在這裏生存。為了調色板上的藍色能屬於天空和大海，白色能屬於瑞雪和浮雲，黃色能屬於陽光和谷堆，綠色能屬於山川和森林;讓你、讓我共同伸出手來，承下昨天交給我們的這份責任。用誠心、汗水、智慧化合成的清泉，刷洗這個世界，贖去我們曾犯下的罪過，交還給自然一個真正的文明。 我們的地球是最美麗的，可是我們不能讓我們的地球毀在我們的手中，這樣的話，我們的後代只會説我們的目光短淺，沒有給他們留下一個美麗的地球，這才是我們一直以來都在痛心的事情，我們的後代還要繼續生活在地球上，可是我們給他們留下的是什麼，是很難被我們救回的地球生態環境，以後的道路還要怎麼樣，我們不知道，可是我現在對大家説，保護環境、人人有責!
各位同學們：
今天我要講的是保護環境的演講稿，題目是《保護環境是不容推御的責任》
讓我們想一想，自從人類誕生以來，一切的衣食往行及生產、生活有哪一樣離得開我們生存的環境，我們生活在地球上，然而地球並不是有我們生存，還有很多很多的動物植物，所有生物的生存，又有哪一樣離得開地球上的大氣、森林，海洋、河流、土襄、草原呢?地球就是由所有的生物組成了錯綜複雜而關係密切的自然生態系統，這就是人類賴以生存的基本環境。
然而，保護環境的演講稿，就是這樣供人類生存的環境，卻總是被人類自己所破壞。人類把文明的進程一直滯留在對自然的征服掠奪上，卻從來不曾想到對哺育人類的地球給予保護和回報，我們人類在取得輝煌的文明成果的同時，對自然的掠奪卻使得我們所生存的地球滿目瘡疤，人口的增長和生產活動的增多，也對環境造成衝擊，給環境帶來壓力。
地球上人類、生物和氣候、土壤、水等環境條件之間存在着錯綜複雜的相互關係，就好比我們人體的各個器官、各種機能之間都是需要保持平衡是一樣的，你想想，我們人類身上的某個器官壞了，人就會生病，就會痛苦不已，其實地球也是如此，一旦失去了生態平衡，便會產生種種不良後果。因為人類的侵害，如今地球面臨了很多的環境問題，比如氣候變暖，臭氧層空洞，酸雨，有毒廢棄物，野生生物滅絕，以及大氣、水污染等等，這些都是令人類頭疼不已的事情，保護環境的演講稿，推薦一篇國小生安全演講稿。
保護環境，人人有責，雖然我們現在還只是個學生，沒有能力去改變那些環境不問題，但是我們可以從小事做起。春天到了，植物開始生長，我們可以積極參與植樹節，保護身邊的花草樹木。除此之外，我們還要愛護身邊的環境衞生，遵守有關禁止亂扔各種廢棄物的規定，把廢棄物扔到指定的地點或容器中，避免使用一次性的飲料杯、飯盒、塑料袋，用紙盒等代替，這樣可以大大減少垃圾，減輕垃圾處理工作的壓力。這一切，看起來不是很平凡的事情嗎?只要我們願意，很輕鬆就能完成，很輕鬆就能參與到保護環境的重大工作當中。
親愛的同學們，你還在猶豫什麼呢?從此刻起，就伸出你的手，伸出我的手，一起去愛護環境，保護環境，我相信，有了每一個人的參與，我們的校園更美麗，我們的祖國更美麗，讓我們時刻謹記保護環境是不容推御的責任。
我的演講完畢，相信大家!您此刻正在本站閲讀演講稿《保護環境的演講稿：保護環境是不容推御的責任》
