carbon做名词炭时是否可数名词

Lower carbon,Happier life
It's our duty to save the energy and protect environment.As far as we know,lately, Global warming has become a very hot issue.And Carbon dioxide is the cause of this.Everytime we're produce CO2.What should we do to make the CO2 become lower?
There are many little things that we can do in our daily life.How do you get to school?By car or bus?It's bad for air.Why not we go to school by bicyle or on foot?That's also good for your health.And we should suggest our parents do that.We can use less plastic bag,not throw away the rubbish everywhere.If the weather isn't hot enough,we shouldn't on the air conditioner,using fan is better.And turn the light off as you go out.You have to summone the whole students to save energy and protect environment. Because a person's energy is not enough.
I hope everyone can keep promise in order to protect our world.

The most important one of pollutants is carbon dioxide.

对于我们来说过低碳生活来保护环境是十分重要的

How to live a low carbon life?As everybody knows, too much carbon dioxide has caused the climate changes. The pollution of the earth is becoming more and more serious. Our only mother earth is in great danger. It is our last chance to try our best to save it. Everyone should wake up to live a low-carbon life to protect our planet.Then, how can we live a low-carbon life? Firstly, we should know that low-carbon life is not only a kind of lifestyle but also life attitude.Secondly, we should develop good habits in our daily life. For example,We can save water by fixing dripping taps. We can save water by not brushing our teeth, not washing the dishes and vegetables under a running tap. We can save water by using used water to water plants or wash WC.We should save electricity. We should turn off the lights when we leave a room. We should turn off the PC (personal computer) and TV when they are not in use. We also can save paper by using both sides of the paper, recycling books, using handkerchiefs instead of paper napkins.Besides, we also should try to reduce the emission. When going to school or work, try walking or cycling instead of driving. Don’t smoke or smoke less. Don’t buy too many clothes. Drink less beer. Plant more trees and so on.I believe, if everyone lives a low carbon life, our earth will become a much better homeland.

地球上大多数的碳来自曾经生存过的东西/事物

Our group choose low carbon life to be our topic on group project.We spent half a month on it and finally made it.
"The villain in the atmosphere is carbon dioxide." said Isaac Asimove.That is.Too much carbon dioxide makes the earth like a greenhouse and become warmer and warmer.Ice melts and climate changes abnormally.It threats our lives and development.However,I only heard of low carbon economy and never heard of low carbon life.I wondered what low carbon life is and how to live a low carbon life.
Later,I knew the concept and importance of low carbon life.Low-carbon life means lifestyle to minimize the energy consumed,thereby reducing carbon dioxide emissions.And we can do a lot to live a low carbon life.There are three principles:"Less meat,less shopping,and more bikes."
To live a low carbon life ,we'd better eat less meat.The entire meat cycle is very very intensive,in terms of carbon dioxide emissions.Scientists also find that producing 1 kg meat will give out 36.4 kg CO2.Have we ever noticed that there are too many people overweight because eat too much meat.So that they have heart diseases and lose their lives slowly.Why don't we eat less meat and keep ourselves fit and strong?Meanwhile,this also helps to live a low carbon life.So ,please eat less meat.
To live a low carbon life,we'd better do less shopping.When we go shopping,we must drive a car or take other transport.These machines are the monsters eating oil and bring out the evil gas-carbon dioxide.At the same time,most of us always buy some useless things when shopping because of some advertisements.In fact,we can live better without them,also we don't need to think about how to deal with the useless things.Producing everything will emission carbon dioxide more or less.So,please do less shopping and buy the very things you need.
To live a low carbon life,we'd better use more bikes.Bikes,unlike other transport,are environmental friendly transport.They don't emission carbon at all.What 's more,it helps us keep healthy.The lever of live is better than ever before but the environment is worse than ever before.So,please use bikes as often as we can and help environment.
Also,there are other ways to live a low carbon life.,such as save electricity,use recycle things and plant trees.
Maybe,you don't agree with me because you think that the economy will be affected,our living quality will descent.That is because you are improvidence and selfish.Have you ever seen that our earth is being destroyed,our existence is being threatened.If we don't pay enough attention to the problems existed,everything will extinct soon,including we human being.And since we already have noticed the problems and known it is wrong to develop with the cost of damaging our earth,it is inevitable to change the methods of economy.Survival of the fittest is also useful for companies.Of course,it is our right to live a luxurious life.But we also know that the resources are limited and will be used up one day.So it is inevitable for human beings to live a simple live in the future.Too much manufacture and consumption make resources into useless trashes.What we need to do is developing the technology and seek for another way of life and economy.
All in all,everyone has the ability and responsibility to live a low carbon life.

Low carbon means low energy and no waste. What can we students do to help with the project?
Firstly, we should save energy. For example, we must turn off lights before we leave to save electricity. We must turn off the tap in time to save water. A no-car day is needed every week in our school. Cars not only cause serious air pollution but also waste energy. On no-car day, every student must walk to school. Use our legs and enjoy the fun.
Secondly, don’t waste things, we should recycle and reuse things. Reuse paper and our textbook, Before we throw the waste, we must sort it. When we go shopping, it is wise to use our own bags which can be reused again and again. In our everyday life, we also have much more which we can save.
Thirdly, we must find ways to stop or reduce pollution. We can write to newspapers to stop factories from pouring waste water into the river and waste gas into the air. The factories must make their waste water clean before it is poured into the river. What’s more, it is good to pick up the litter whenever we see it.
Finally, we must plant more trees. Trees can not only clean our air but also make our world more beautiful. They are good for our environment. Good environment can make us live happily and healthily. At the same time, we must stop the people cutting down trees.
In a word, it’s our duty to improve our environment. To improve the environment means to live a low carbon life.. As students, we really have a lot to do. Lower carbon, happier life. Let’s take actions now.

My Low-carbon Life
Energy saving and Environment protection are giant projects and have a profound effect on the whole earth and all human being's future. However, everyone could make a 'trivial' contribution to them, and the accumulation of our good deeds could make them more easly. What are the good deeds? That includes many things, and could vary a lot for every person. For example, we students can walk to our school instead of riding cars. We can turn off the lights, fans, TVs and so on when leaving the classroom. We can turn off the tap whenever no water is needed. We can also reuse the water to the utmost. There are still much, much more good deeds than I just mentioned. Can you also think of one or two?
But remember, only thinking and talking would not help to your own contribution. So keep these good things in mind, but more importantly, let's do them every day from now on!

有利于发展低碳经济的新钢材

As we all know, everyone in the world has the reponsebility to protect the environment. What could we do? Firstly, we should go to school on foot or ride bike. For our parents, we could suggest them go to work riding bike.Secondly, we should put the things we don't use for recyle. Just like the books we have used, we could give them to younger students. In that way, we could save more paper resources. Moreover, we could also do something for environment. Perhaps many of us have experience like that we bought many clouthes, but we don't like them at last. In accordance with this phenonmence, we could put clouthes in some bags or boxes, then we deliver it to the charitable institution. At last, they will deliver that to the people who need them. In this way ,we not only save resources, we help the poor people who need help. We should do our best to economize resources to make the lower carbon life come true.

We are the masters of the Earth and the Earth is our home which we should protect, Do not pollute the Earth. Low-carbon living is actually very simple, as long as we do not waste resorces , we can save some energy for the nature , for the earth to do many good things.I remember one summer whose weather is hot like a steam boiler. we were feeling the earth is fulling of fires. My father and mother were hiding in the house, opening the air-conditioning, After a while, my father was transferred the temperature to 26 degrees Celsius, and I said: "Dad , turn the air conditioning off.Fan is enouht cool 。 Dad said：" You are a good boy because you know how to save the energy . "So close to the energy-saving living and low carbon life,.As the world's economic development, population increase in a large number of climate in recent years.More and more carbon dioxide were emitting.The Earth's ozone layer subjected to unprecedented pollution.The world's environment has a serious health hazard to human security, so we have to protect the global environment.Low-carbon living is an attitude.We should save electricity, water, carbon, fuel-efficient.Such little things of building low-carbon life is the green way of life.

9.2碳循环
9.2.1碳
水库是一个水槽或来源的元素,例如碳.有各种全球性的碳水库,其中有些是巨大的规模和其中一些规模相对较小（表9.3 ） .最大的碳是碳酸盐岩储层中发现地球的沉积物.这4个水库的数量级大于碳酸盐岩储层中发现海洋和6个数量级大于碳水库发现大气中二氧化碳的.如果考虑这三个水库,很明显,最可用的碳进行光合作用是在最小的水库,大气中.因此,它是最小的水库是最积极循环.这是小国,积极循环水库,如大气中二氧化碳,受人类活动扰动.事实上,由于全球工业化始于1800年代末期,人类已影响到几个较小的碳库.利用化石英尺!埃尔斯（一个例子,一个小,无效碳水库）和砍伐森林（一个例子,一个小,活性炭水库）有两个活动,减少了大量的有机碳固定在这些水库和添加到大气二氧化碳水库（表9.4 ） .
增加大气中二氧化碳未如预期般大.这是因为水库的碳酸盐岩中发现的海洋作为一个缓冲区之间的大气和沉积物碳水库通过平衡方程所示.
因此,部分多余的二氧化碳已被释放已被海洋所吸收.但是,仍然是一个净effiux的二氧化碳到大气中约7 〜 109万吨/年.的问题,这种不平衡的现象是,由于大气中二氧化碳的是一个小碳水库,由于持续的净effiux在过去100年左右的时间里一直是28 ％ ,增加大气中二氧化碳从0.026 ％至0.033 ％ .的后果,增加了大气中二氧化碳的是,这可能有助于全球变暖的温室效应.温室效应所造成的气体在大气中的陷阱来自太阳的热量,造成地球升温.这种效应不仅是由于二氧化碳;其他气体,如甲烷,氯氟化碳（ CFCs ）和一氧化氮添加到这个问题.

1、sea level 指海平面
sea levels coastal area是指与海平面处于同一海拔的沿海地区
coastal areas 泛指沿海地区
2、low carbon living 指低碳生活
low carbon life 也是低碳生活（之生活方式） 两者无本质区别
3、studies['stʌdiz]n.研究；学习；学业（study的复数） 希望对你有所帮助

有不明白的请继续追问,

我做了一个关于人们如何过低碳生活的调查.他们中的大多数正在尽力这么做.这里有一些调查结果.迈克住在学校附近.所以他骑自行车去上学或步行.他认为两种方式不仅可以使他保持健康又保护了环境.吉娜去购物时使用布袋.这是一个真正的好想法.大卫经常打开窗户.他很少打开空调.辛迪在餐厅从来没有使用过一次性筷子和杯子.因为可以用,所以她通常使用自己的杯子.我认为他们都是环保人士.

日前,一种新的生活开始流行.它是低碳生活.它意味着低碳排放以及零污染.
下面是一些过低碳生活的方法.首先,我们应该尽量走路或骑自行车而不是乘坐汽车.其次,我们必须尽量不用一次性筷子.这个是低碳生活最重要的部分.
就我个人观点而言,低碳生活让世界更美好.
顺便想说一下,这个英文片段有的地方有问题,还有就是后面有单词拼写错误……

ecome carbon neutral成为碳中性（二氧化碳的排放总量）
