关于保护动物的一篇英语作文【汇总19篇】

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

动物是人们的朋友，我们应该保护它们。

地球上如果没有动物，就没有人类。动物是这个地球生物链的一大部分，如果动物消失了，我们人类也会灭绝。例如：青蛙消失了，就没有动物去捉稻田的害虫，农作物也就无法生长，人类就没有食物；如果没有老虎，兔子就会超额繁殖，我们的粮食就可能会被兔子吃没了；如果没有猫头鹰，老鼠就会侵占我们的地盘。……

地球是一个大家庭，缺谁都不行，如果没有动物，我们人类的处境可想而知，我们大家应该团结起来，保护小动物。

Dear brothers and sisters,

On behalf of the University Students Union, I, the Chairman of the Union , am earnestly calling for your active participation in our environmental protection campaign. It is the duty of every global villager; man just can not sustain his glorious civilization without a rewarding environment, which will be possible only if man makes considerable efforts to protect the environment.

Do you cherish precio us opportunities to volunteer in our joint efforts in environmental protection? Here is a great one not to be missed by any enthusiastic youth; Right next Saturday, our university is to run a publicity campaign to advocate environmental protection across the city. The University Students Union will be in charge of recruitment of volunteers. Lets join our hands and take action immediately.

“保护动物”这四个字我们每天都在说，可是又有多少人在用实际行动表示呢?被割掉胸鳍和尾鳍的鲨鱼，被割掉角的犀牛，用洁白的象牙制作的装饰品，活熊取胆……这一件件残忍的事情时常发生，申赋渔的《逝者如渡渡》叙说了数百年间，世界各地灭绝了的或正在走向灭绝的30多种动物的故事，如：日本象.指猴.象龟.渡渡鸟……它们都是人类的伙伴，它们也曾快乐的生活在这个地球上，可是，因为人类掠夺了它们的生存空间，使它们从地球上永远消失了。

全球变暖，使北极熊赖以生存的浮冰断裂.消融。也使他们的食物——海象.海豹逐渐减少，使北极熊频临灭绝;人口迅速膨胀和乱砍乱伐，使熊猫的生存范围被迫向竹子稀少的山顶推进，食不果腹成了家常便饭，当竹子开花时，有些野生熊猫会因找不到食物而饿死。熊猫虽是我国的“国宝”，可在全世界的数量也不过区区2000多只。

人类啊!醒悟吧，让“保护动物”不只是说说而已。动物是人类的朋友，是地球大家庭中的一员，动物同人类生活在同一个地球上，动物作为食物链中的一员，如果动物灭绝了，那么人类也逃脱不了灭绝的厄运。

动物是有灵性的，它们也有思维和感情，人类怎么能忍心去杀害它们呢?每一个物种的消失，都是人类走向孤独的脚步，没有了动物的陪伴，人类还能走多远?保护动物绝不仅仅是一个组织的责任，大自然为大家所共有，保护动物，人人有责。但愿每个人都问一下自己，自己的行为曾经给地球带来过怎样的伤痛?自己有没有为一时的利益而透支我们的未来?

由于环境恶化和人类的大量捕杀，鲸目成员特别是一些大型成员由于经济价值高而受到广泛捕猎，许多鲸类已濒临灭绝。让我们保护鲸鱼，让它们不再受到伤害。

保护鲸鱼的英语作文【篇二】

The existence of the oceans allowed the first life to form, grow, and reproduce. T he oceans create atmosphere, weather, and climate. They supply the world with an abundance of life, much of which sup plies humans, among others, with transp ortation, food, medicines, and recreation . While other species may enjoy the ben efits of the oceans, humans have becom e so wide spread and detached from the world around them that they have effect ively brought the oceans to the brink of extinction in a very short time (Woodard, 2000). While the oceans count time in th e billions of years, humans count time in years or decades. In the last fifteen deca des, human activity has decimated a sig nificant portion of the ocean, creating "d ead zones" where there is no oxygen to support life. The ocean chemistry is beco ming dangerously acidic due to the burni ng of fossil fuels and the dumping of was te in the oceans, and may trigger a non-r eversible chain reaction of extinction, sa y before the end of this century (Global warming, 2006). The goal is to motivate, educate, and offer possible solutions to t he problem, however it will not work unt il people across the globe work together.

Protect Traditional Chinese Culture

The passage mainly tells us the importance of protecting traditional Chinese culture, which is challenged or facing extinction because of the developing society and changing lifestyle. Besides, China is nationwide sparing no efforts to do it.

The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious development between local economic and social development. It is reported that the Guangdong government pays special attention to protecting Chaoju(潮剧)， a local drama born in Chaozhou in the eastern Guangdong province.

In my opinion, some measures should be taken to protect traditional culture effectively. To start with, we should make a law to regulate the society’s performance. Besides, we should draw more people’s attention to it, for the more they know about the importance of culture protection, the stronger the support we can get from the public.

In a word, it is high time for us to treasure and develop our own valuable culture.

全市的小朋友们：

小动物是我们人类的好朋友，请求大家好好保护它们吧！不要用石头、棍子打伤它们，它们有血有肉会痛的，会哭泣的，它们的爸爸妈妈会心疼的。小动物们为我们地球的生态平衡做出了巨大贡献，因此，我们特向全市小朋友们发出以下倡议：

一、不要打小动物，不要捕捉小动物。

二、多照顾小动物，把无家可归受伤的小动物送到收容所。

三、向全社会广泛宣传保护小动物的重要意义。

四、认真学习小动物的生活习性，学会保护小动物的知识。

小朋友们！让我们心连心、手拉手，共同为保护小动物事业做出贡献吧！保护小动物协会成员：林思宇

小动物是我们的朋友，我们应该爱护它们。因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右;可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。 还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。

它捉害虫的时候两条后腿一蹬，一纵身，敏捷地将后腿一蜷，跳起老高，长长的舌头一伸，就像一个吸尘器一样转眼就把害虫吃到肚子里去了。可是，我们人类却把它们当成美味佳肴摆在餐桌上。 还有许多可爱的动物，我最喜欢的是大熊猫。大熊猫是我国珍贵的动物，妈妈告诉我大熊猫还是我们国家的国宝呢!大熊猫长的很可爱，胖乎乎、圆滚滚的，走起路来一摇一晃的，特别逗人。它的头部和身体都是白色的，只有眼圈、耳朵和肩部是黑褐色的。特别是那一对黑黑的眼圈，长在白白的脸上，像是戴着一副墨镜，加上那笨拙的动作和走起路来东张西望的神情，显得像个小绅士。

你瞧!它们多么可爱，它们是我们人类的好朋友，我们怎么忍心伤害它们呢

i like animals very much. i have a dog, it’s my favourite animal. it’s white, it looks like a snow ball. it has two big eyes and ears. but its nose and mouth are very small. it’s very naughty.it often stares at my food when i have a meal. when i’m home it follows me all the time.

i like my dog very much.

Today the quality of our natural environment has become an important issue. The world

population is rising so quickly that the world has become too crowded. We are using up our

natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some proGREss in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.

今天的质量保证我们的自然环境已成为一个重要议题。世界人口增长如此之快以至于世界已经变得太拥挤了。我们正在用尽自然资源,同时,用化学危险品污染环境。如果我们继续这样做,地球上的生命将无法继续存活。

有关人员有了一些进展在环境保护。许多国家的政府都制定了法律以保护空气,森林和海洋资源并停止环境污染。

更多措施应该被采取解决环境问题。受过教育的人应该是进一步认识问题的重要性,要运用现代控制生育的方法来保存(保存)我们的自然资源和循环(再循环)我们的产品。我们相信,我们可以有更好的和比较干净的地方,在未来的。

Protection of Environment

1. 目前环保还存在着许多问题。

2. 为了保护环境，3. 各国政府做了大量的工作。

4. 我的看法。

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. Fi

rst, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

保护环境

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。

为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。

我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

1． 世界人口越来越多，环境污染也随之严重。

2．污染治理情况。

3．需进一步采取措施。

Environmental Pollution

With the explosion of population in the world, more and more poisonous waste is produced. As a resuit, a lot of rivers and lakes are polluted. In some areas, the air also becomes dirty and harmful. Consequently, animals and plants are endangered. And peopies health is greatly affected.

Fortunately, more and more people have realized the serious situation. Many countries have passed laws to prevent the environment from being further polluted. People are working hard to find ways to keep the earth clean: they treat waste gases, protect water sources and purify waste water. Definitely, controlling the increase of population is one of the most efficient ways.

However, in future more efforts will be needed to win the battle against pollution, The laws controlling pollution must be strictly enforced, And above all, attention should be paid to the education of the people so that everyone will show his concern about environmental protection

1.环境污染

与世界上的人口爆炸,越来越多的有害垃圾产生了。作为一个结果,许多河流和湖泊被污染。在一些地区,空气也变得又脏又有害。因此,动物和植物濒临绝种。和人们的健康>

庆幸的是,越来越多的人们已经意识到这种严重情况。许多国家已经通过了法律来阻止环境受到进一步的污染。人们正在努力想办法使地球保持清洁:他们对待废气、保护水资源和净化废水。可以肯定的是,控制人口的增加是一种最有效的方式。

然而,在未来将需要更多的努力赢得了战斗反对污染的法律控制污染,必须严格执行,而且最重要的是,在教学中应重视对人民的教育,使每个人都将显示他正在关注环保

A larger and larger part of society is expressing its concern about environmental protection. Active in their concern, teachers and students hold specific meetings to discuss environmental protection. Also, city planners take environmental problems into serious consideration. And, though reducing pollution can be expensive,

factories often take every possible measure to do their part. Many people are concerned and active because air and water pollution affects everyone and makes it difficult for cities to survive and businesses to make a profit.

一个越来越大的社会的一部分是表达他们的担忧关于环境保护的。活跃在他们所关注的,教师和学生举行特别的会议来讨论环保。同时,城市规划者们把环境问题进行认真的考虑。还有,尽管减少污染可能会很昂贵,生产厂商经常会采取一切可行的措施来履行自己的职责。许多人都关心和积极的,因为空气和水的污染影响每个人都大打折扣,使得城市生存和企业盈利。

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.

大家都认识熊猫，它们既可爱又机灵，不但淘气，还会自我保护。

熊猫很机灵。它经常让小林鼠自己跑出来让它吃，当然也会使用一些计策。

它还很淘气。有时，它趁猎人不在家，大摇大摆地闯进去，偷吃猎人的野味。吃完了，还把勺子仍得远远的，甚至把锅挂在树杈上。

当敌人来时，它能很好地保护自己，不被敌人吃掉。

但是，现在，像熊猫这样可爱的野生动物也越来越少了，豚鹿、梅花鹿那样的之前在小山坡上就能看见的动物，现在早已不见了踪影。

朱鹮、金雕、白鹤这些华丽、美丽的鸟儿们，在几亿年前曾经数不胜数，但现在只能在动物园里才能见到它们的美丽的模样了。

巨蜥、扬子鳄、蟒，这些动物虽然很危险，但也是重要的野生动物物种，对自然界的生态平衡也起着一定的作用。

说到这儿，你们想到了什么呢?我们不能因为他们的肉美味，就随便乱杀。它们可怜，是因为它们的兄弟姐妹越来越少;它们害怕，是因为自己有被杀的风险;它们生气，是因为我们的过度开发，它们的领地已经越来越小了。

从现在开始，不要再乱杀野生动物!从现在开始，不要再大量开发森林!不要再破坏动物和动物的家园吧!

Campus, such as flowers, sending out the intoxicating fragrance, sending out the breath of love; Campus, such as the rain, has nurtured us, training us; Campus such as dreams, so beautiful, so sweet. I love this garden like campus.

"Green campus", to beautify the campus. Our campus change green and beautiful. Appered, picked a flower and grass, a flower bed, added to life, our campus look brand-new.

"The air is fresh, clean and tidy environment, buildings, surrounded by green trees", who dont want to in such a clean, sanitary, healthy growth of the beautiful campus learning? But a variety of reasons, our campus environment is gradually damaged by bad behaviour of some of my classmates. Now in our beautiful campus, there have been some uncivilized phenomenon, some students randomly throw debris-brick, plastic bottles, sunflower seeds, etc. Whenever naughty wind these waste, running here and there, tinkling like a child, helpless, we can only watch them on campus "dance", and even some classmates in the scribble on the white wall and the desk carved, and disorderly spit phlegm, and so on. All this, cannot match with our beautiful campus. See these phenomena, how would you feel? Learning life can make you happy?

Protect the environment, is to protect human survival environment, make the earth from pollution. Environmental protection consciousness, starts from me, starts from dribs and drabs, start with a small paper scraps.

The classmates you know? "Environmental protection" this two word write very easy, but it is very difficult to do. If we dont do "environmental protection", then maybe in five years later, maybe after ten years, maybe in the future one day, and what will happen to our world? May be a grey day, you can see garbage everywhere, every some time will come a sandstorm, would come so many people unable to imagine...

I really did not dare to imagine again, write down again, this really is terrible. But now how many people are really in the environmental protection? You see, every trash can next to have full of rubbish. Although the rubbish is only one step away from the trash, but around and no one will put the rubbish into the trashcan, you both do turn a blind eye to it; How many trees have been cut down, sent to the factory, to make a one-off chopsticks, for those who covet convenient use, make it match, make paper towel... And then to the market to sell. I think if these items will talk, they would have said such a sentence: "wake up! Dont damage the environment again, dont destroy our home again, you will regret later. Dont you dont want to be a family? Dont want the earth? If you want these things, then began to protect us, and begin to protect your dribs and drabs around!"

Now you may have a little regret! Maybe thinking about a variety of ways to save the world, to save our home! Actually very simple, we just have to start from around things. See waste paper fell to the ground just bend over to pick it up; See saplings fall down, just a few friends together, righting it together, together to help it grow; Protect wildlife, covet them delicious meat, that no longer will they brutally skinned meat; To open a small speech, called on people to protect the environment, protect the people and objects around. Every little bit, starts from the minor matter, starts from the side, hard for the earth.

Let us act, protect the environment, do a good job in environmental protection. Dont let the noise of the earths environment is damaged again!

保护环境，就是保护人类生存的环境，使地球不受到污染。环保意识，从我做起，从点点滴滴做起，从一张小纸屑开始做起。

同学们你们知道吗?“环保”这两个字写起来十分容易，但是做起来却十分的困难。如果我们不做到“环保”，那么也许在五年后，也许在十年后，也许就在未来的某一天，我们的世界又将会变成什么样子的呢?可能是天灰蒙蒙的，到处都可以看到垃圾，每隔三两天就会来一次沙尘暴，就会来许许多多人们无发想象的事情……

我真的不敢再想象下去、再写下去了，这真的太可怕了。但是如今又有多少的人是真真正正地在环保呢?你们看，每个垃圾桶旁都有数不胜数的垃圾。尽管这些垃圾离垃圾桶只有一步之遥，但是四周围来来往往的人没有一个人会将这些垃圾投入垃圾桶内，大家对它都不约而同的做到视而不见;有多少棵树在被砍伐，送往工厂，做成一次性筷子，给那些贪图方便的人使用，做成火柴，做成纸巾……然后到市集上去卖。我想如果这些物品会说话，他们一定会说这么一句话:“醒醒吧!不要再破坏环境了，不要再破坏自己的家园了，你们以后一定会追悔莫及的。难道你们不想要家了吗?不想要地球了吗?如果你还想要这些东西的话，那就请你们开始保护我们，开始保护你们身边的点点滴滴吧!”

现在大家也许有点后悔了吧!也许在想各种各样的方法来挽救这个世界，来挽救我们的家园吧!其实很简单，我们只需从身边的小事做起。看到有废纸掉在地上就弯腰将它捡起;看到小树苗倒了，就几个小伙伴合力，一起将它扶正，一起帮助它成长;保护野生动物，不再贪图它们那鲜美的肉，将它们残忍地剥皮吃肉;开一次小小的演讲会，呼吁人们保护环境，保护身边的人和物。一点一滴，从小事做起，从身边做起，为地球而努力。

让我们行动起来，保护环境，做好环保。不要让地球的环境再次受到破坏了!

There are all kinds of animals in the world . My favorite animal is rabbits. It has two long ears, a pair of red eyes, and a short tail. It likes jumping. It likes eating carrots and cabbages. It is one of the worlds most lovely animals.

对人有益的动物有很多，例如有蜻蜓、青蛙和小燕子等等。

我们先说蜻蜓吧，它是益虫，它对人的益处可多了。它生活在小池子旁边，捕捉害虫。有些人，捉蜻蜓，捕蜻蜓，捉住后到处卖。我们应给立一个保护蜻蜓法，如果他们再敢捉蜻蜓，捕蜻蜓，就是知法犯法，交给警察叔叔处理。

青蛙也不例外，它也是捕捉害虫的能手，不过，它生活在庄稼附近的池子旁边，有时候，它也到庄稼地，旁边捕捉害虫，人们都称它保护庄稼的好帮手。有的小朋友，到池子旁边，捕捉青蛙，回家后，吃青蛙。我们应该在池子旁边树一个牌子，上面写着“保护青蛙，人人有责”，这样就不会有人捕捉青蛙了。

小燕子也是捕捉害虫的一类，它生活在大树的鸟巢里，它在天空捕捉害虫。有些人，用枪把小燕子射下来，回家吃了，或者卖了。我们应给设一个森林保护区，让小燕子和其它受保护的动物住进去，这样，既保护了小燕子，也保护了其它的动物。

如果没有这些有益动物，害虫就会增多。这样，连农药和灭害灵都不行了。我们应给共同保护动物。

Animals are our friends, they live together with us on the same planet, we should take care and protect them, and they let us know we do not know many of the knowledge.

When we want to animal fur and all the time, until you want to protect you when they have been cruel extinction, and animal protection is to protect ourselves.

Our society in constant development, our living standard has been improved, but my door but misses the point, that is environmental protection.

You see, lawn grass became yellow, and the roadside trees listlessly, dense forest under the handfuls of sharp saw also gradually away from us. This, but the fact that iron!

In the countryside, people cultivation of levelling, and so many trees lost their lives, however, these precious land because of improper use, was a wild field soil. In this way, a vast expanse of land with a large abandoned, year after year, day after day, past the dense forest will one day be a state long, become a piece of the other people hate the boundless gobi desert!

Everybody should know area Tuo lake, the biological variety there, especially the hairy crabs there, with a meat tender yellow, more and more the favour of people. Now, Tuo lake surface is covered by algae is full, the water had turned out to be a tan. And also the dead fish floating in the lake, garbage, and black water plant, are miserable sufferings

Careless human ah, you wake up, we live on the earth has not been able to afford, the forests on the earth in the sharply reduce, desert and wilderness is a miraculous increase. Clean fresh water resources is constantly reduced, however, dirty ChouShui river is in the unceasing increase, shouldnt, all is false?

Want people to listen to me a advice: please dont covet interests and cut down a tree, please dont waste water because of the naughty. Although these are only some things, but the cumulative up one by one and is a great thing. I believe that in the near future, our world will become more beautiful.

我们的社会在不断的发展，我们的生活水平也在不断的提高，可是我门却忽略了一点，那就是环境保护。

你瞧，草坪上的小草变黄了，路边的大树无精打采，茂密的森林也在一把把锋利的电锯之下渐渐的离我们远去。这，可是铁一样的事实!

在农村，人们垦荒造田，许许多多的树木就这样失去了生命，然而，这些宝贵的土地有因为使用不当，又被沦为荒田野土。就这样，一大片一大片的土地被荒废了，年复一年，日复一日，昔日那茂密的森林总有一天会一反长态，变成一片另人讨厌的茫茫的戈壁沙滩!

大家应该都知道五河沱湖吧，那儿的生物品种繁多，特别是那儿的大闸蟹，，以个大肉嫩、黄多而倍受人们的青睐。而现在呢，沱湖水面上皆被水藻覆盖满了，水竟然变成了黃褐色!而且湖水中还漂浮的死鱼、垃圾、还有黑乎乎的水草，真是惨不忍

糊涂的人类啊，你们醒醒吧，我们赖以生存的地球已经承受不了了，地球上的森林在急剧的减少，沙漠和荒野却奇迹般的增加。干净的淡水资源在不断的减少，然而，肮脏的臭水河却在不断的增加，难道，这些都是假的吗?

希望人们听我的一句劝告：请不要因贪图利益而砍树，请不要因为贪玩而而浪费水。虽然这些只是一些小事，但是一件件累计起来，就是一件大事。我相信，不久的将来，我们的世界将会变的更加美好。

A triple bacon cheeseburger seems like a heart attack on a plate.

三层奶酪咸肉汉堡感觉吃完很容易让人突发心脏病。

So how can polar bears thrive on their version, seal blubber?

那么,北极熊是如何处理这些高热量食物的呢?

Turns out theyve stocked up on genes that let them clear fats from their blood.

结果显示它们储存在遗传基因里的信息使得它们能够清除血脂。

Thats according to a study in the journal Cell.

这是根据《细胞》杂志上的一篇研究得出的结论。

Polar bears are well adapted to life on the sea ice.

北极熊非常适应在浮冰上的生活。

Up to half their body weights fat, which gives them extra insulation and buoyancy, and provides them with a ready source of energy.

几乎占它们身重一半的脂肪足以使它们保暖并且维持体力，提供给它们一种易转化的能量。

But how can an animal so fat also be so fit?

但一种动物怎么能又胖又健康?

Researchers compared the genomes of polar bears with those of brown bears, and found that polar bears have accumulated genetic changes that boost their heart health and fat metabolism.

研究人员们通过比较北极熊和棕熊的基因，发现北极熊的基因组中积累了不少有利于心脏健康和脂肪代谢的遗传突变。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

These genomic changes happened quickly, evolutionarily speaking.

这些遗传变化从进化的角度来讲发生的十分快。

Polar bears and brown bears diverged from a common ancestor less than half a million years ago.

北极熊和棕熊都来自于同一个祖先，它们是在大约50万年前左右开始向不同分支进化。

But if that seems super speedy, the ability to digest lactose didnt spread through human populations until we domesticated cows, just 10,000 years ago.

但是如果这种变化看上去十分快速的话，消化乳糖的酶逐渐进化到人类各个种群中也还是发生在大概1万年前我们可以驯化乳牛之后。

A moooving testament to the power of natural selection.

这是自然选择力量的证明。
