“low-carbon” is one of the most popular buzz-words in this year. not only china but all countries focus on the topic of “low-carbon”.
here, i’d like to share my own experience abroad with you. several years ago, i was very lucky to have an opportunity to live in the australia about half a month. during that time, not only did i enjoy the beautiful natural scenery there, but also i appreciated the people’s active way of protecting their environment. now, whenever the environment protection is mentioned, the beautiful scenery of australia will arise in my mind, white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and lovely squirrels playing happily among the trees.
as a citizen of china, if everyone can actively protect the environment in our daily life and if we would like to reduce our carbon footprint, the scenery of blue sky, green grass and lovely animals in australia will appear in china, even in hefei.
but i totally support the view, that is to say, emotion without action is irrelevant! do you unplug electronics after you use them? do you switch off everything before you go to sleep? do you adjust your tv screen a bit dimmer to save energy? do you re-use water for different activities around the house? each of these seemingly insignificant adjustments in your daily life can make a difference in saving the environment of tomorrow.
we all know that nothing is more comfortable than sitting in the warmth of a hearted car while it’s snowing and hailing outside in the freezing cold…but with global warming and even global cooling becoming more pressing by the day, not to mention your own health, take a walk ,ride a bike ,reduce your carbon footprint on the environment is said that tiny streams can be combined into a vast ocean, small trees can be an immense forest, and every little makes a mickle.
“low-carbon” is not just a buzz-word but a goal that people from all over the world wanna get. so, reduce carbon footprint! reduce damage! save energy! save the world!
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.
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 (这里可以停顿一下)which 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
centigrade in the last 5 decades. It is higher than the reported global average. We are seeing more frequent bouts of extreme weather in many parts of the country. For example, last spring, the most severe drought in 50 years hit northern China affecting the livelihood of 4 million people. Environmental damage and climate change is a reality for us. Out of the world?s most polluted 20 cities, half are in China,70% of Chinese rivers are polluted . China has become the largest carbon emitter of the world.
It is really thought-provoking(发人深省). Who pays for it ? First,as the pace of human high-tech development process goes quiker and quiker, the side-effects with the science development reflected, global warming is one example. more and more greenhouse gases with the development of economy are being discharged into the t 70% of the greenhouse gases has been composed of carbon dioxide,which is considered as one of the greatest causes of global warming . It has harmful effects,causing the sea level to raise and many natural disasters to strike. On the other hand , scientists in one wave after another try to awaken us to the growing threat of global many coutries tend to turn a deaf ear(充耳不闻) to the scientists? fact,the earth?s atmosphere is definitely being warmed and the problem is largely man-made. A wise way is that we should get moving to protect ourselves. So the public demand that all nations should taket strong measures to prevent the increase of the earth?s temperature.
In my opinion, it is the high time for us to take action. In order to save the earth, we should try to do things below: no air conditioning, use recycled paper,abandon meat food, don?t use plastic bags,take a is little drops of long as everyone takes action, it will be a powerful strength to rescue our planet. All countries are supposed to take the legislative initiative as soon as in this way can the global warming be put under control.
In some places, the air and water pollution is so serious that it causesmany deaths. At the same time, many animals and plants are in danger because ofthe destruction of their habitats. so a low carbon life is becoming more andmore popular among people. A low carbon life can be of great use for us efore, we must take the necessary measures to reduce the environmentalimpact of carbon dioxide. But what should we do for it ?
In my view , First of all, as students, we should go to school on footinstead of driving a car. Cars not only let out carbon dioxide but also wasteenergy. Second ,we had best not use plastic bags which can bring about the whitepollution. We should use the environmentally-friendly bags. Third, it's of greatuse to plant trees. Trees can absorb carbon dioxide and release oxygen. Now wecan from our own, to promote low-carbon living.
From now on we started operations! I believe that only we do thus can wehave a better living environment.
My honorable judges:
With the high level of development of technology today,our lives have become more and more comfortable,wearing beautiful clothes,eating delicious food,and playing with modern of us think that we human beings are the cleverest of all the animals around the there is no doubt that we are have created a large number of successful the other hand,we are also destroying the environment and bringing death to many kinds of animal.
No man is an re of is a piece of the continent.
There is no hope for human being if we continuous killed animals ,It’s time to do something to save dolphins,animals,and human ’s join our hands together to make the world better!
Thank you very much for your attention.
In recent years， the global warming gets increasingly attention. More andmore people make contribution to stop the global warming. Therefore， a newlifestyle occurs--low carbon life. What can we do to live in low carbon?
近几年，全球气候变暖越来越得到关注.越来越多的`人为阻止全球变暖做出贡献.因此，一种新的生活方式诞生了——低碳生活.在低碳生活中我们能够做些什么呢?
First， remember to turn off lights and turn off the faucet when you do notneed to use. Use the energy-saving lamps. There are many small things we can doto save resources. Second， when we go out， take public transport as much aspossible， to reduce gas emissions and to ease the transporting pressures.
首先，但你不需要用电和水的时候，记得把灯和水龙头关掉.使用节能灯.我们能够做很多小事来节省资源.其次，当我们外出的时候，尽可能乘坐公共交通以减少气体排放和缓解交通压力.
All in all， there are many other things we can do to live in the low carbonlife. It needs us to do something practically. If everyone can keep thislifestyle from now on， it will greatly change the situation and our home wouldbee more beautiful.
总之，为了低碳生活，我们能够做很多事.它需要我们做出一些实际行动.如果每个人能够从此刻起持续这种生活方式，状况将得到很大改善，我们的家园会变得更美丽.
Hello! I wonder whether everybody knows the meaning of these two words of " energy-conservation " and " low carbon "? I assume as a matter of course and know. Does " energy-conservation " save the energy? Does " low carbon " reduce carbon emission? Yes, it is really simple. We often chat about them. But, do you really understand them? Have they really taken root on your bottom of heart deeply?
Once, the Earth mother left our rich energy to cause us to be jubilant, sighed on Earth's energy inexhaustible, inexhaustible, now, the newest statistics indicated, the petroleum will dry up after 60 years, the coal also might supply the humanity to use for 250 years; Once, developed first, the environment question the situation which neglected is often occurred, now, the sustainable development, was together harmoniously with the nature the biggest difficult to see, the environment question in is taken unceasingly by the all this, the environment question was still stern, the energy conservation reduced the platoon, the low-carbon lives the Copenhagen climate congress, this affects the human destiny the question slowly to be unable to reach the agreement the life, is driving the great displacement automobile, purchases including the fluorine air conditioning, the refrigerator, including the phosphorus laundry powder, turns on the air conditioning the low temperature also one side to bind in the summer the quilt, the daylight lamp is being long all night clearly, water cock water drop sound day and night not e influence environment phenomenon common is rebels with ours position. American President Kennedy has said: Do not have to ask the country can make any for us, must ask first oneself can make any for the low-carbon life needs everybody to participation!
As time goes by, man is making the earth sick. People cut down too manytrees and leave rubbish everywhere. Factories let out their waste without doinganying to it . This has cause some serious problems. Such as the land is sandy,the river is dirty, the air is less clean, even the temperature of the earth isrising. What should we do to save the earth ? My suggestion is that we shouldplant more trees, put rubbish into dusbins and stop factories pouring wastedirectly into the air or rivers. In all, we have only one earth, we should doour best to protect it, or we will regret.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous.
DEMAND for graduates in the UK with skills related to sustainability is booming. Academia is waking up to the need to train specialists in green architecture, chemistry and engineering.
Dean Millar founded the world’s first ever BSc course in Renewable Energy at Exeter University after working as an industry consultant.
He said： “A lot of companies were complaining that there was a lack of bright young people suitably trained to work in the renewables business.”
Now his course has around 90 students learning the ins and outs of biomass, tidal, solar and offshore wind power.
Their career prospects are incredibly bright. Employment opportunities are not just limited to the energy sector, but segue into the regulatory and, increasingly, investment sectors as well.
“The big boys are moving in. The returns to be had are significant, especially in terms of wind development,” said Millar. “Financial firms need expertise across the board so they can make sensible investment decisions.”
Students on York University’s Master’s course in Green Chemistry are ideally placed to take advantage of the growing demand in industry for graduates with waste minimization skills.
Professor James Clark is founder of York’s Green Chemistry Centre for Excellence and the world’s leading green chemistry journal, Green Chemistry. He said： “We are now talking to producers of automobiles, electronics, furniture and pharmaceuticals, people who need to use chemistry but don’t think of themselves as chemists.”
As waste production legislation becomes increasingly strict, the traditional emphasis on making as much of a chemical as possible is shifting towards minimizing the waste that process creates. “A lot of chemicals are made from petroleum, but we are developing sustainable ways to make carbon, typically from biomass such as dead plants and trees,” said professor Clark.
All of last year’s graduates quickly found employment, some receiving multiple job offers in a variety of different fields.
Li Li, a 26-year-old Chinese postgraduate student, graduated from York in 20__. She said：
“I hadn’t heard about green chemistry in China. It was a new area and I was curious. Now the government back home needs people who know about these principles.”
Deep in the heart of Wales, 400 students at the Centre for Alternative Technology’s (CAT) Graduate School of the Environment are busy designing and building everything from high insulation wood housing to wind power turbines. With energy costs rising, building firms are increasingly looking to minimize the energy wasted heating and lighting homes, a service CAT students are well-equipped to provide.
A new institute is being built to meet the burgeoning demand for places and a distance learning facility will be launched next September so foreign students can complete CAT courses from home.
The expertise being taught on these courses is essential to a continually expanding range of companies and government authorities. Yet there is a larger goal at stake; the students are at the forefront of the battle against climate change. In the words of Dean Millar, “If we’re going to save the planet, we need to start turning these people out in big numbers.”
Now more and more people are focusing on the nature. It is no doubt that the nature is important to every human being. No nature, no life. Because of the supplies of the nature, we have lived happily for a long time. And we started to gain every thing available from the nature. And this lasted so long a time. Today, people have discovered that the nature around is getting worse and worse.
What is threatening the nature? Air and water pollution, overharvesting of plant and animal species, overpopulation and so on. Overpopulation is the biggest source of pollution. Let's take overpopulation as an example. What does overpopulation feel like? When we move slowly through the city in a tazi. When we enter a crowded slum district. When the temperature is high and when the air is thick with dust and smoke.
The streets are crowded with people. The streets seem alive with people. People eating. People washing. Improving Beijing's environment for the Olympics Ladies and gentlemen: Good morning! Today, the title of my speech is Improving Beijing's environment for the Olympics. Have you ever seen animals cry? Do you know what makes them cry? It's the polluted world, a dirty world, caused by our irresponsible behaviors, that makes those lovely animals cry. Many of us are smart enough to know how terrible it is to have a world without animals and plants. But some people still persist in making the same errors and harming the environment. What's worse is that people are eating wild animals. Those people don't know, and more importantly, they don't want to know. This kind of behavior has caused some specific problems.
For example, medical experts have suggested that eating wild animals helped spread the terrible disease SARS. Now, our world is no longer clean and beautiful. Why? Because air, water, and noise pollution has become more and more serious. Noise pollution makes us talk more loudly and become angry more easily. Water pollution makes our rivers and lakes very dirty. Air pollution is the most serious kind of pollution. Both air pollution and water pollution are not only dangerous to our health, but also dangerous to animals and plants. We're destroying our only world. A large number of trees have been cut down, so a lot of lands have been turned into deserts. Pollution can be seen everywhere! Unquestionably it is essential that we clean up our environment. Sadly, we've not always appreciated the importance of protecting the environment.
On the streets, you can see cars producing smog. In the bathrooms, you can see students leaving the water tap on after using them. Not only the young people, but also the elderly ones throw things everywhere without thinking it's wrong, even in a beautiful park. these things are taking place every day, even in modern cities like Beijing. We can't do that any more. We must learn how to protect the environment. If everyone is aware of protecting it instead of destroying it, the world can become cleaner, more beautiful, and more peaceful. The theme of Beijing 20xx Olympic Games is "New Peking, New Olympic". It's the target owned by every Chinese. We should try our best to improve Beijing's environment for Olympics. , let's begin to act! First, start with the things around you. Don't throw rubbish onto the road. Don't talk loudly when you are outdoors. Turn off the water tap after using it. Go to school by bike or by bus instead of by private car.
Save your pocket money and contribute to environmental protection organizations. Take me as an example, I take action in order to make our only world full of happiness. I pick up rubbish and throw it into a trashcan. I collect waste paper or bottles for recycling. I plant more trees and flowers, and so on. If you do all these things just like me, it means you have done something useful to improve the environment. We're grateful, because the emblem of the Beijing 20xx Olympic Games is a precious treasure dedicated to the Olympic Movement by the people of China. Under the guidance of the Olympic spirit, let us do a better job in all fields of our preparation and venue construction work in an efficient way.
We will combine the Olympic Movement with the latest technology and advanced culture to make the Beijing Games the best Olympic Games ever! Welcome to Beijing! Thank you.
With the development of science and technology，people are attaching moreand more signifance to low-carbon lifestyle. There is no denying that we shouldlead a low-carbon example ，we should turn off the light when we leavethe classroom，turn off the water tap when we finish washing and so on. What'smoreFurthermore，it's our duty to lead a low-carbon life，which does good to ourenvironmentsustainable us lead a low- carbon life !
As you know , theres 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 theres 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 . Its 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 cant 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.
Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers. Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.
We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.
