Dear teachers, students everybody is good!
The title of my speech today is: “protect the environment, start from the spot.”
As we all know the per person per day to save a piece of paper, a year can save much paper? 4745 sheets of paper, also can cut less 1.581666 million trees a year, “1.581666 million” this is what a staggering! In this sense, save paper, afforestation.
Car is also damage the environment a great sinner, day after day he exhaust, contains large amounts of carbon dioxide. Is the earth to produce “greenhouse effect”, “the temperature gradually warming, gradually melting glaciers, sea level rise, land area will reduce gradually. Scientists expect that by 2050, China will have 48 cities, under the threat of flooding in different city. At our side, there are not many environmentally friendly behaviors... So to protect the environment is not a moment to rest.
So, how do we protect the environment? Use paper, a use up dont throw away, can be used on the back, both sides after use, fold it up and sent to the recycling paper mill. Drive is the same, let parents to drive a car to work less, more than ride a bike, can exercise the body, and can reduce carbon emissions, so it is with open air conditioning, we less open air conditioning, electric fan, additional variety of some trees and flowers, so to protect the environment and help?
The students in small power is power, a root chopsticks a break, the three and five? We must pay attention to environmental protection, with students as the ”green small guard!“
Thank you all!

we all know tagore.this famous indian poet once said, “life is given to us, and we earn it by giving it.” as the saying goes, nature is given to us, and we earn it by contributing to it. however, most people nowadays just want to ask for more from the nature. in fact, they do very little contribution to the nature. therefore, the environment around us is becoming worse and worse.
do you often use batteries? then do you know it takes 50 times more energy to make them than they produce? and just one simple battery can pollute as much water as a person can drink in his whole life. the facts and figures are amazing. so would you please try to use batteries only when it is necessary? if possible, give the used ones to the recycling companies so that they will be made into new ones and won’t be able to pollute the environment any more. sometimes we become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everybody can understand, people become much clearer about the problem.
we, as school students, can also join in recycling activities to protect the environment. for example, our class set up a recycling center beside the back door, it is very useful. it is used to collect the waste paper and plastic bottles. in the past, our classmates used to throw all of these into the trashcan. at the very beginning of this collecting activity, it was not so warm-welcomed. later, more and more people were influenced by the others and joined this collecting activity. gradually, all the students in our class form a good habit to protect the environment. all of us will now put away the reusable things instead of throwing them into the trashcan.

1 沙尘暴的起因机理分析
1.1 物理过程分析
沙尘暴的发生步骤可概括为分离、输送和沉积3个过程。当风力达到使土壤颗粒运动时, 土壤颗粒的分离就发生了。分离的土壤颗粒在风力作用下或在空中或沿着土壤表面输送移动。当风速降低时, 颗粒就会沉积。
1.2 动力学分析
从沙尘暴的动力学原理来说, 在干旱的气候条件下, 强风使裸露、疏松、干燥的土壤表层颗粒分离。直径在0.5~1.0 mm的大颗粒, 因为质量大, 通常只能在土壤表面滚动;直径在0.1~0.5 mm的颗粒, 通常只在短时间内随风而起, 由于重力作用很快便落下来;只有直径小于0.1 mm的土壤颗粒可以被大风刮起来, 悬浮到空中, 随风输送到很远的地方。悬浮颗粒的数量一般由土壤表面微粒多少来决定, 而不单纯受风能大小的制约。
引起土壤颗粒在风流中开始移动的风速值叫临界风速值。临界风速值取决于土壤覆盖物和土壤的可侵蚀性。有植物或植物残茬覆盖时, 土壤临界风速值比光秃表面高, 板结地面比疏松地面土壤临界风速值高。已知农田没有固定的临界风速值, 它取决于土壤耕作和作物状况。
据分析, 沙漠中小于0.1 mm的细小颗粒不到2%~3%, 而农田中细小颗粒占40%以上。因此, 细颗粒主要来自农田和退化草原。
我国广大的北方地区属大陆性干旱、半干旱气候, 年降雨量为200~550 mm, 旱地面积达2 000×104 hm2, 占总耕地面积50%以上。当地十年九旱, 年降雨量460 mm左右, 旱地面积2.9×104 hm2, 占总耕地面积4.5×104 hm2的60%以上, 长期以来, 沿用传统耕作方式, 使地表裸露, 水土流失严重, 为沙尘暴的形成创造了客观的自然条件。所以, 防治沙尘暴的重点应放在北方农田和退化草原上。
2 沙尘暴的防治对策
国际上沙尘暴的防治对策归纳为2点:一是设置风障, 包括林带、灌木丛、高的谷物, 以及对准风向的田间带状作物等, 以改变风向和风速, 减少土壤颗粒的相互分离和输送, 增加沉积作用;二是改善土壤表面状况, 提高土壤抵抗风蚀作用的能力或限制土壤颗粒运动, 减少和控制农田风蚀, 主要是利用生长的作物和残茬的保护作用。
3 保护性耕作的环保效应
3.1 保护性耕作技术内容
旱地机械化保护性耕作作为旱地农业保收耕作方法之一, 其核心内容是通过深松、浅松等少耕、免耕措施, 在尽量不翻转土壤的前提下播种施肥, 尽量减少对土壤耕层的破坏, 从而减少水分蒸发;秸秆直接粉碎还田, 保持尽可能多的茎叶残茬覆盖地表;用化学药剂除草、防治病虫害。
3.2 保护性耕作的经济效益分析
通过对比实验表明, 较传统方法种植小麦, 保护性耕作法种植可增产45.48%;免耕播种减去了传统耕作的翻耕、耙地、整地3个环节, 每0.067 hm2节约费用18~20元, 免耕播种土壤翻动较小, 有利于保蓄土壤水分。田间测定, 免耕播种地块10 cm深处, 土壤含水率为16.8%, 而传统播种地块土壤含水率为14.2%;免耕播种比传统播种提前出苗7~10 d, 苗全苗壮。因此, 保护性耕作具有增加产量、降低成本、保墒蓄水诸多好处。
3.3 保护性耕作的防尘效果分析
保护性耕作法是最大限度地减少土壤耕作和将作物残茬留于地表的耕作法, 是一种改良的、集约的防治水蚀和风蚀的作物生产方法。
保护性耕作法由于采取了少耕免耕措施, 取消了许多传统的耕作作业, 如耕翻、耙耱、平地等, 使地表下松上紧, 抗风雨侵蚀能力大为提高, 同时, 土壤中最肥沃的富含有机质的细小粒子被紧紧包裹于地表之下, 使能随风起舞的土壤微粒减少到最低程度。
另外, 由于作物残留物覆盖地表, 能有效地减少大风引起的沙尘颗粒运动, 既可以吸收一部分风力, 减少风对土壤的作用力, 又能保护土壤颗粒不被风力移动, 从根本上杜绝了沙尘的起源。

保护环境 保护生命 第4篇
泥石流俗称“走蛟”“出龙”“蛟龙”,是暴雨、洪水将含有沙石的松软的土质山体饱和稀释后卷走而形成的洪流,泥石流大多伴随洪水而发生。它与一般洪水的区别是洪流中含有大量的泥沙、石块等固体碎屑物,因此它比洪水更具有破坏力。当泥石流即将来临时,我们应如何判断、应对呢?
思考
其实,历史上,舟曲森林茂密。但长期的森林砍伐,导致植被被严重破坏,舟曲的水土保持能力变得越来越差,无雨则旱,有雨成涝,一旦下雨,泥沙俱下,便形成了泥石流。舟曲自然生态系统的调节能力和涵养水分的条件已经丧失。
科学与经济的发展给人类社会带来了巨大的进步,可是当人类经济活动违反自然规律时,必然遭到大自然的报复。甘肃舟曲特大山洪泥石流给我们当头棒喝——保护环境就是保护我们自己!
办法
躲避不是最好的办法,保护环境就是保护自己,我们需要科学应对。对付泥石流,上海世博会“城市最佳实践区”展出的沙特麦加米纳案例馆就提供了一个好例子:每年伊斯兰历十二月,从世界各地而来的300万穆斯林朝圣者聚居到沙特的米纳帐篷城(见下图)。从远处望去,一个个白色的帐篷紧密排列几乎布满山谷,这里的人口密度已达每公顷5000人,万一发生泥石流等山体滑塌事故与洪涝灾害,后果不堪设想。为了确保300万朝圣者的安全,沙特政府采取了一系列有效措施:①在岩石山上造梯田。可以在灾害发生时对山体滑落的岩石块进行缓冲,削减石块下落的冲力;②在沙土较为疏松的山上使用田网。可以在山体滑塌时让下落的泥沙兜入田网,不掉下山去;③向山体岩石内钉入钢筋并浇筑混凝土防护墙,以加固山基。此外,沙特政府还在米纳帐篷城周围的山上建造了先进的排水系统,以防止因雨水过大而导致的各种山体事故。山上筑有不少大坝,坝下积水通过各种管道将水引流出去,到达各个专门的蓄水池。蓄水池内的水经处理,还可以为山下300万朝圣者提供生活用水。

Class:
hello!The protection of the environment is getting more and more attention. However, I find that there are many uncivilized phenomena on our campus. I saw people spitting on campus, people throwing rubbish, and people destroying trees and breaking flowers. How dangerous these uncivilized behaviors are to the world! If everyone spit and throw rubbish, how dirty the road is! If there were no trees and flowers, would our earth still be able to live? So, protecting the environment, we should start from every little thing around us.
Lets go, class! Be a civilized student, protect the environment and create our beautiful homeland together.

My name is Zhang Junyi, I’m a lovely girl.
I’m from ZhangCun primary school.
Today, It’ s my great honor to be here.
The title of my speech is “To Be a Good Traveler”.
I love traveling very much.
I’m so exciting to visit different places.
It’s a good way to make new friends.
Moreover, It’s like reading a book.
Yes, I love traveling.
But I hate to see that environment has changed worse and worse.
Many unknown places are built into resorts, trees are cut down, rivers and lakes are polluted.
But to our delight, our government has become more and more concerned with the protection of the environment.
The government has been doing a great job.
And what about us? What should we do? It’s just one step to take, for you, for me, for everyone.
If every tourist uses less plastic bags, how much white pollution would disappear; if everyone tries to reach one place of interest on foot, how much clearer the sky would be; and if no guest asks the hotel to change towels every day, how much less detergent would be drained.It is not difficult, right? It’s just as simple as the famous slogan, “Please take away nothing but your smile, and leave behind nothing but your footprint.” I believe that we all love our earth.
So, now let’s turn our passion in to action.

保护环境的英语演讲稿:Give environment more care
Good evening, ladies and gentlemen. My topic is “Give environment more care”. I’d like to talk about some global environmental problems, share some of my stories and show you some data in my speech.
At the beginning, I’d like to ask you a question. Has your hometown’s environment been polluted, if it has, raise your hands please? (Thank you) Let me give you an impression of my hometown. That is a small village of Yunnan province. There are many mountains, forests and rivers. If you go there, I promise you will be amazed by its beautiful landscape. Because you just can touch the nature with your fingers and feelings. You can enjoy the blue sky, flying birds, waterfall, amazing sunset and many other sceneries. When I was a teenager, I often climbed these mountains and jumped into clear and clean river for a swim with my peers. However, after my graduation from high school, I came to Beijing for college. I found something different. Because when I raised my head, the sky’s color was not blue, but yellow. When I looked down, dirty and poisonous rivers are full of unrecyclable rubbish and giving out unpleasant smells. When I looked forward, so many people wore their mouth masks. Everyone here complains weather and environment. It seems so inharmonious between man and nature. Why?
As we know, in the past few centuries, human have made countless remarkable achievements in science and technology to explore the mysterious world better. Conquering nature with powerful tools, people have achieved material prosperity. Meanwhile, environment has been badly damaged. So a series of severe problems come along, such as species extinction, energy crisis, incurable diseases, the three main pollutions etc. All of these factors bring our beautiful planet disasters, humanity as well. Let me show you some statistics. According to the report from World Wide Fund for Nature, the species of entire world have declined by 52 % since 1970. That means about 75 kinds of precious species disappear forever from the Earth each day. In addition, scientists claimed that human now need one and a half Earth to meet the demand for natural resources. Another frightening data from the UN in , there are almost 8.4 million people around the world who die of cancers caused by environmental issues every year. It is so horrible, isn’t it? Man has taken too much from nature, also paid such a heavy price for it. If we don’t try to change these situations, what will happen one or two centuries later?
But, fortunately, the majority throughout the world are aware of the significance of environmental protection. Much many individuals, environmentalists and organizations have taken actions spontaneously. Companies donate part of their profits to support some green projects. Moreover, Government has carried out many policies to conserve endangered species, support green industries and encourage people to live a green life. From a global perspective, though it is a long journey to make the Earth recovered and to live in harmony with it, I do believe that, with everyone’s efforts, we will finally get there.
Ladies and gentlemen. For ourselves, for our children, and for all human beings, by the end of my speech, I do hope you can keep the following words in mind ---- The nature’s prosperity is humanity’s prosperity. Caring environment is caring human’s future. Lives need be valued by us, nature need be respected by us, and the Earth need be loved by us, please give them more care. (Thank you very much. Ladies and gentlemen.)

Protect the environment is the duty of everyone, we are just some students , we couldn#39;t make something especially big contribution for the environment , but we can secondary composes up in our environment , from protecting schools#39; environment, for example: Observe in connection with the regulation forbidding chaos to throw away various waste , avoid using the drink cup , mess tin , plastic bag for one time merely , use paper box to wait in the place or container throwing away waste to appointment, replace, such can cut down a rubbish greatly, lightening refuse disposal job pressure , treasuring flowers and plants trees , being the cleaning giving to New Year card as a gift , keeping campus short and so on.
Although these being minor matter at above ,but if everybody gets to do, set about from saving resource and falling off contaminating, self life-style adjusting an once, we are therefore likely to be to protect the earth making a contribution out.

I’m very proud that I have chosen to speak to you all today, I’m a bitnervous as I’ve never made a speech before to so many people ,so please forgive me if it shows.As we all know,the environmemt around us is getting worse and worse.In some places we can’t see fish swimming in the river or trees on the hills.Some people even have no clean water to drink.So I think we must do something to protect the environment..But what can we do? How to protect our environmemt? For example, we can go to school on foot or by bike.we can use shopping basskets not plastic bags.when we go shopping and we can use both sides of the paper when we write.In a word ,if everyone pays more attention to our environment ,there willbe less pollution and our life will be better.“There is only one earth”,I hope everyone will protect our environment well.Thanks!
亲爱的校长、老师、同学和朋友:
今天,我很自豪的是,我已经选择与你说话,我有一点紧张, 我从来没有在这么多人面前讲话,就请原谅我是否会表现出来的。
我们都知道,我们周围的环境越来越糟了,在某些地方,我们不能看到鱼在河里游泳或树木在小山。一些人甚至没有干净的水喝。所以我认为我们必须做些什么来保护环境。,但是我们
能做些什么呢?如何保护环境吗?比如,我们可以上学步行或者骑自行车。当我们去买东西时,我们可以用购物袋, 当我们写东西时,这张纸两面都可以用。总之,如果每个人都非常重视对我们的环境、污染就越少,我们的生活将会是比较好的。
“只有一个地球”,希望每个人都能保护我们的环境。谢谢!
The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially.Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment.Therefore, We need some countermeasures from the viewpoint to prevent the city
environment form disaster and to manage environmental risks.So we will develop and improve a new risk management system and a disaster
prevention system to preserve and create the city environment where people feel easy and sound in their life.地球规模气候的变化带来了一种新型的自然灾害和发达和复杂的城市体系,手里拿着一个潜在风险扩大伤害人工。同时,人们已经弄坏了健康的化学品的数量巨大以来,已经产生了使用方便、追求生产各种有毒物品堆积,无心环境。因此,我们需要一些解决这些问题的观点来防止城市环境形成灾难和管理环境风险。我们将开发和改进的新的风险的管理制度和防灾系统维护并创造城市环境,让大家感到轻松,声音,在他们的生活。
Some people believe that economic development should never be at the cost of the environment.They think the present serious environmental problems are largely caused by rapid?economic development.For example, land resources are shrinking because of the industrial development and the expansion of cities.Deserts are spreading because of over grazing, poor fanning, tree cutting, and strip mining.Our air and water supplies are being polluted by poisonous gassesand waste products.It is important, therefore, that we should take another look at the way in which our industries and cities are developing.However, other people think it unnecessary to consider environmental problems now and our first priority should always be given to economic development.They believe that environmental problems are
inevitable and unavoidable in the process of economic development.They are only the by products of economic development, which can be dealt with later when we have the time and money.I think the second idea is completelywrong.Our ultimate aim in economic
development is to provide a comfortable and happy life for our people.What is the point of economic development if we achieve it at the cost of our
environment? There has been much evidence to prove that a balance between the two helps more rapid and continuous development.有些人认为经济发展不应该在环境为代价。他们认为目前的严重的环境问题在很大程度上是造成快速?经济发展。例如,土地资源正在收缩因为产业发展和扩展的城市。沙漠是传播因为过度放牧,可怜的耕作、树切割、、剥去挖掘。我们的空气和水的供应是被污染有毒废物。它是很重要的,因此,我们应该再看我们的工业和城市发展。
保护环境英语演讲稿 第10篇
Good morning, dear teacher and classmates!
It’s my honor to stand here to give my speech.The topic of my speech is “Protect the Environment, Protect Ourselves”.As we all know, the environment around us is getting worse and worse.For example, I hate the air in Beijing, because it even can’t be clean for two or three days in a week.The duty air can not only let you feel bad, but also bring you cancer.Not long ago, I heard from news that a foreigner in Beijing insisted running in the morning, however it didn’t help him keep fit, on the contrary, and he got cancer after two years.What do you think about it? Are you afraid of the killing environment?
At this moment, no one can doubt that our environment is getting worse and worse.In the past several decades, hundreds and thousands factories were built in China everywhere.To be honest, it =================made profit for us, but when it was shut down what did it leave us? It left us duty water, polluted air, useless earth, even the disease.One fair happened in my hometown can be a live example.When I was around 6 years old, I enjoyed swimming with friends in river, walking along the ridge, picking wild fruit on the mountain, listening frogs singing in the night, and so on.However, good times don’t last long.A few years later, a factory was built in my hometown, as a result, the water in river became duty, the air was not fresh anymore, the frogs in the field was gone and the environment became worse and worse.Personally speaking, I hate the factory;I hate the duty air and duty water!I miss my previous hometown!
