讓我們過上幸福的生活；大自然，有時候，就像一個魔鬼，讓我們過著悲慘的生活。下面是小編為大家整理的環境與發展的英語演講稿，如果大家喜歡可以分享給身邊的朋友。
Ladies and gentlemen,
I feel it a great honor to have a chance to give a speech here, talking about the haze weather, which causes lots of bad effects on our health and life. We breathe polluted air, making us suffer from lung and liver diseases. Besides, because of it, the flights have to be canceled. All kind of transports may run into each other, resulting in much damages and lots of injuries.
As far as I am concerned, it is high time that we did something. As individuals, we should ride the underground or buses instead of cars to reduce carbon dioxide. As government, more measures should be taken by carrying out the related law on pollution.
In summary, we're all looking forward to breathe fresher air and live a happier life. Everyone should be a part of this job.
Thank you for your listening.
we have only one earth. but now,the environment becomes worse and worse.
as you know,there's no enough clean water for people. so many of them lose their lives because of water.
in a lot of countries, people have to cut trees for living. so there's nothing to keep water from running away. also we have polluted the land, the river and the air. so we have to face more and more floods and droughts .
it's time that we must do something useful to protect our environment. we can plant trees and take good care of them. we can save the water and ask our parents to do so. we can't throw any litter onto the ground and we should collect them for recycling.
if we take good care of our earth today,it will be more beautiful tomorrow.
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.
Comparing with the past,do you feel any warmer these days?Maybe you don’t take much notice of it.Nevertheless,on account of the burning of fossil fuels,the temperature has been increasing during the 20th century.In consequence,green house gasses(mostly CO2)trap heat from the sun and therefore warm the earth,causing both rising of sea level and terrible climate catastrophe.Presume that the temperature keeps on going up,no bright sunshine will visit us,unclear air will choke us and heat waves will kill us mercilessly.
However,much to our delight,nowadays countries and some organizations are aware of the importance of cutting the producing of carbon-dioxide.The U.N.Climate change conference opened in Copenhagen,Denmark on Dec.7th,20__ arouses great concern from experts and officials,us included.Besides,in China,an effective law system has been set up to avoid producing too much greenhouse gasses.
Well goes a saying that protecting the earth is protecting ourselves.At the same time we are supposed to undertake the responsibility to lead a low-carbon lifestyle,which is of great significance.Needless to say,low-carbon lifestyle means a lot to our society.First of all,so great a method is it to control the global warming that we are bound to make good use of it.Moreover,to some degree,it contributes a lot to our health.
Absolutely there is a diversity of measures we can take so as to lead such an environmental-friendly life.For one thing,it is known to us all that large quantities of greenhouse gases are produced mostly by motor vehicles so that we,if possible,can walk or ride to school instead of depending on cars all the time.For another,we should spare no efforts to reduce energy in our daily life,for energy in the world today is decreasing rapidly.For instance,we can turn off electrical appliances if not necessary as well as using recycled materials.Furthermore,at our leisure,we can seek opportunities to plant more trees which can absorb carbon-dioxide.Last but not least,we are responsible for calling on others to lead low-carbon lifestyles.
In brief,low-carbon lifestyle is nothing but the best choice for us and only in this way can we form a harmonious relationship with the environment.
we are a normal member of the big family of nature good afternoon everybody. honorable judges, ladies and gentlemen. today，we are gathering here to discuss a very hot issue. how to find harmony in a new age between man and nature? where modern science and technology are concerned i am only a layman i have to say. however, living in this new age , seeing my dear ones suffering from respiratory diseases from time to time, finding the beautiful colors of green and blue are being replaced by that of gray and pale, and realizing that our mother planet is getting more and more unhealthy; i cant help trying to offer my idea and my trivial efforts to look for the answer of the question. as the ancient greek oracle goes: know thyself. i think in answering this above-mentioned question, this precondition is also very important. who are we? this is a question, which should be answered not only by those specialists, but also by every one of human beings. some people may proudly say: we are the masters of nature.
it is true that the idea of man can conquer nature has dominated peoples mind for years, and it is true, man has kept acting like a master and doing whatever things he wants for thousands of years. however, as the consequence of this kind of leadership , now the master seems to be confronted with problems that are far beyond his control. facts are really very ample. the green house effect leaves islands and cities along the coast, such as this oriental pearl-shanghai, in danger of the disaster of being drowned; the holes of the ozone layer make the earth less suitable to live for some creatures including human beings; the phenomena of el nino and la nina leave the land with serious flood and drought, and the diseases, caused by pollution, are increasing at an incredible speed... seeing all these facts, can we still ignore the counterattack of nature? we are not the masters of nature. facing all the disasters made by ourselves, we, mankind as a whole should realize that we are just a normal member of the big family of nature. any mistreatment towards nature will meet only with the revenge from her. by saying so, i do not mean we should give a sudden stop to any development. because that will result in a threat to the existence of human society. i mean we should treat nature
equally, leaving the chance of existence and development to nature as we are obtaining the same thing, and thus we will get the situation of win-win. i am very pleased to find that now more and more people, from every corner of the planet, have come to realize that harmony with nature is the only way to universal and continuous progress and prosperity. and i think that is why we come here from all over the country to discuss this topic today. i want to end my speech by quoting from mr. nixon. our destiny offers, not the cup of despair, but the chalice of opportunity. the future is not ours to see of course. however, by seizing firmly the opportunities, by knowing clearly about ourselves, we, human beings, can doubtlessly achieve the real harmony with nature! thank you very much.
