关于保护动物的一篇英语作文(通用20篇)

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

My Views on Environmetal Protection

Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.

If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.

Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

Earths biological diversity is being fast decline of many species facing extinction.Threat to the survival of wild animals and plants is a major factor in habitat loss， business development， and wild animals and plants and their products in international trade.Resources are limited， it is necessary for the endangered species， to propose specific measures of protection level.We can formulate the corresponding endangered species laws， application to establish nature reserves， endangered species breeding centers， means of conservation biology， endangered species， the implementation of in situ conservation and ex situ conservation.At the same time， we must restrict international trade in Endangered Species of Wild Fauna and Flora， to make laws to protect endangered species。

In our common home - the earth, life with a lot of animal, which animal do

you like? Anyway, my favorite animal is our most loyal friend - a dog.My

favorite is my neighbors dog that Beijing BaGou yuan yuan and collie handsome.

They play together every day, it is a good friend of a stick dozen not

scattered, I also like them, they saw I was shaking his tail towards

me.Handsome shape tiger is big, the body is about more than 60 centimeters

long. Two leg, capable to my shoulders, his eyes, nose, mouth, ears are much

older than yuan yuan, I most like to see him running figure - curly float in the

sky, like a nice horse. I often and yuan yuan, running with the handsome, every

time is handsome first, second, I am the third round. Can literally, handsome

running faster than thoroughbred horse. Average dog ran up, send out "clicking"

sound, but handsome rans voice is very small, not carefully is inaudible. The

appearance of the handsome run is also very handsome, curly, bow shaped body. If

you want to use a word to describe talent, that is: handsome. If you use a word

that was impeccable.Compared with the handsome, round shape is much smaller,

only 30 centimeters in length and a half smaller than talent. The meaning of his

name from his eyes, it is too round. Like a shiny black stones. And his legs are

very round and round this is name. And his legs are very short, so even if he

runs, casting its foot also run fast, but I still like him very much the kind of

Protecting birds is part of our jobs of protecting our own living environment. Imagine you live in a place with green trees and colourful flowers. The little birds are flying around and singing happily. Its such a wonderful place to live. On the contrary, if we damaged the nature, chopped all the trees and kill all birds, we will live in a desert where has no living creatures. What a boring live would be! Therefore, we should protect birds as we protect our childern and ourselves future.

我们都知道动物们是我们人类的朋友，它们和我们共同生活在地球上面，跟我们享受一样的资源，但是现在社会上会有很多虐待动物和宰杀动物的行为，这些行为都是很不好的，我们要懂得保护动物，让他们和我们一起生活在美丽的地球上。

最近新闻上总是会有一些虐待动物的新闻，比如说一个男就把自己怀孕的小猫关在了笼子里，活生生的用热水把它烫死了，我觉得这样都是非常没有人性的行为，既然领养了这只动物，就应该好好的对待他，对她负责，而不是用这样的方式来折磨她，我觉得这样是很没有人性且没有良心的，这种行为也应该受到全社会的谴责。然而这个社会上面这个男人的做法并不是隔离甚至在生活上面有很多人会有这样的行为，他们虽然领养了动物，但是却没有好好的对待动物，反而去折磨他们，虐待他们，让他们受到了不好的待遇，又会受到了摧残，还有一些人会对不是自己的宠物的动物虐待和折磨，比如说有的生气的人就会把流浪猫和流浪狗作为出气筒给他们身上发泄，对待他们殴打他们这些猫猫狗狗就会受伤，甚至会被殴打致死，都是非常残忍的。

小动物们都是我们的好朋友，他们和我们共同生活在地球家园上面是我们的陪伴，所以我们和动物之间应该和睦的相处，特别是现在有一些动物已经濒临灭绝了，被设立成了国家的保护动物，但是有一些人执法犯法，野外去捕杀这些保护动物，违背了国家的法律也是没有人性的，这些行为都是不对的，我们每个人都要增强保护动物的意识，让我们和小动物们和谐相处，共同生活，

在美丽的地球家园上。

My favorite animal is a chicken.

As it happens, my home downstairs is no. 307 to raise a few chickens. Every day, we pass these chicks are partial his head to see us.

The chicken body furry and cute. A yellow feathers like wearing a yellow dress. The chicken has a pair of sharp mouth. Round eyes also pretty mentally?

I dont see their ears, but the chicken could not have no ears. If no ears, that we walk past, how they head, look at us with a partial?

Mother said that newly hatched chicks also can only eat a small grain of rice, cant eat corn or maize, and gave them drink water regularly. If there are bugs to eat them. Theyll grow more air.

How much I love these cute chicks. But mom and dad said cant keep now, dont keep good, they will die.

我最喜欢的小动物是小鸡。

恰好，我家楼下307号就养了几只小鸡。每天我们经过时，这些小鸡都偏着脑袋看我们哩。

小鸡全身毛茸茸的，很可爱。一身黄黄的羽毛像披着一件金黄的礼服。小鸡有一双尖尖的小嘴。圆圆的眼睛看人时还蛮有精神的呢。

我没看到它们的耳朵，但是小鸡不可能没有耳朵。如果没有耳朵的话，那我们走过去时，它们怎么会偏着脑袋朝我们瞧呢?

妈妈说，刚孵出的小鸡还只能吃小米粒，不能吃谷子或玉米，还要经常给它们喝水。要是有小虫子给它们吃，它们一定会长得更神气。

我多喜欢这些可爱的小鸡呀。但是爸爸妈妈说现在还不能养，不养好的话，它们会死的。

全世界每天有75个物种灭绝，每一小时就有3个物种被贴上死亡标签。很多物种还没来得及被科学家描述和命名就已经从地球上消失了。动物也是一个大家族，他们形成一种食物链，每一种动物都是这个食物链上的vip。

人们现在大肆地杀害鲨鱼，只为了取鲨鱼那仅有的两个鳍。被取鳍的鲨鱼不会立即死去，而是因为失血过多而痛苦地死去。当人们在餐桌上津津有味的品味着高价钱买的鱼翅时，难道没有一丝的悔过吗?鲨鱼也知道疼啊，他也是一条活生生的生命啊。

事实上，近几年来，因为工业废水不断地排入海洋，每年进入海洋环境的石油高达两百万吨以上，使得海水中重金属含量较高，而鲨鱼处于海洋食物链的顶端，吞食了其他鱼类后，食物中的重金属也随之进入鲨鱼体内，积累下来，因此鲨鱼体内的重金属的含量会越来越多。

有些人虽然知道怎样去爱护动物，可是他们只会假惺惺地去教育别人，而自己却照样破坏环境，猎杀动物，照样兴致勃勃的品尝动物上的鲜美的肉味。就拿我们身边的小狗来说，虽然不是国家一二级别的珍贵的动物，但也是我们身边的好仆人，不管主人怎么使唤它，它仍然很兢兢业业，可是人类看见小狗的肉鲜美，人们还是捕杀小狗，如果当时人们有保护动物意识的话，就不会造成这样的事了。

朋友们，动物的大量毁灭对人类将产生严重的不良后果，造成生态环境严重不平衡，从而使人类的生存环境遭到破坏。消灭动物，就是在消灭人类自己，如果有一天世界上的动物全都消失了，那人类还能生存吗?要保护动物，珍惜这自然界里的每一个生灵吧!让我们从现在做起，从我做起，保护动物，使世界变得更美好吧!保护动物，就是保护人类自己。

In recent years， many nations have bee more aware of the environmental issues each nation faces， such as air and water pollution。 The question is， are the environmental issues a national problem or an international problem? It is my belief that the environmental issues have grown to the point of being an international problem needing international cooperation to resolve。

Because of the differences in environmental policies， resources and technology， international cooperation could provide quicker results and have a greater impact on bringing resolution to environmental problems for nations of differing environmental policies and of lesser resources and technology。 By pooling international resources and technology to address the environmental problems， the disadvantaged nations are provided the assistance needed。 Otherwise their environmental conditions deteriorate ultimately affecting the resources and environment of the world as a whole。

One of the difficulities to an international resolution to environmental issues is the difference in individual nations view and policies toward environmental protection。 In order for international cooperation to occur and succeed， the nations of the world must submit themselved to international standards and supervision by an international mission elected by the participating nations of the world。 All members must agree to abide by the standards established。

The environmental issues facing each country are not unrelated to the well being of the rest of the world。 The impact is long term and international in scope。 Without international cooperation and agreement to address such environmental issues as glacial melting at the South Pole， depletion of the ozone layer， water pollution， air polution， etc。， the environmental conditions of the world will deteriorate to the detriment of every nation， not just those that ignore or lack the resources and technology to resolve their individual environmental problems。

As part of the same planet， it is the responsibility of each individual and nation to protect the global environment。 Only international cooperation will provide the timely solutions and the effectiveness needed to stop the deteriorating global environment。

Hello, everyone. I’m am a student in No.1 Middle School. I’m very proud that I have been chosen to speak to you all today.How to protect/save our environment/world?

The environmental pollution is worse and worse /more and more seriously today. Water is polluted ,we have no clean water to drink Many trees are cutting down, some animals is getting less and less.Some factories is poring dirty air in the sky , the population is increasing faster and faster ,resources is getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future.

The first fact I worry about is noise pollution. People can"t sleep well if there is too much noise. That"s why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn"t make terrible noises. If they make terrible noise that isn"t allowed, they will be fined, and we can also produce the cars which can"t make terrible noise.

The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.

我每次去动物园，我总是逆着人流，一进大门，就往左拐，去看望我最喜爱的大鸟-天鹅

星期天的早晨，我又和爸爸、妈妈一起去动物园。那天霞火初红，湖水平静一对天鹅在水面划过，他们拍打着宽大的翅膀，托出了红艳艳的朝阳。

天鹅长着一身雪白的羽毛，显得格外美丽。它们在湖面上娴静得、慢慢地游动着，那平静的湖面像一面明亮的大镜子，倒映出他们那高难度的身影，就像一对舞蹈队员在跳双人舞，使我不禁想谈一首天鹅舞曲，为他们伴奏。游了一儿，也许是累了，便进岸边休息了，树下的房子就是天鹅的家。在这美丽的绿色草坪上，他们静静的望着，远远望去，仿佛是一座雪雕。

我爱天鹅，天鹅是爱美的象征。许多文学家都写过天鹅的故事，好比安徒生爷爷写的童话......看到天鹅，我就仿佛进入了童话世界。

Many wild animals are facing the danger of extinction，because the environment that they are living in has changed greatly。For example，with the developmet of cities，the using of insecticide and serious pollution，their living areas have bee narrowcr and narrower。Many of the wild animals，now are confronted with food crisis。At the same time，man is killing off species just for getting their fur，skin，horns，teeth and meat.In order to protect our resources of ecology，people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty。There fore，measures of the following should be taken:pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life，reserves.Only if we human beings take some drastic measures can wild animals be preserved。

Environmental pollution can cause direct damage and impact to ecosystems, such as desertification and forest damage, which can also cause indirect hazards to ecosystems and human societies. Sometimes the harm of this indirect environmental effect is greater than the direct hazard caused by it, It is more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone depletion are the environmental effects derived from atmospheric pollution. This environmental effect derived from environmental pollution is lagging behind, often at the time of the occurrence of pollution is not easy to be perceived or expected, but in the event of environmental pollution has been developed to a very serious point. Of course, the most direct and most environmentally conscious consequence of environmental pollution is the decline in the quality of the human environment, affecting human quality of life, physical health and productive activities. Such as the citys air pollution caused by air pollution, peoples morbidity and so on; water pollution so that the deterioration of water quality, drinking water quality generally decline, threatening human health. Serious pollution incidents not only bring health problems, but also cause social problems. With the increase in pollution and peoples awareness of the environment, due to pollution caused by population disputes and conflicts increased year by year.

Let us all love nature, love the earth, hand in hand, shoulder to shoulder, heart to cast a green embankment, to defend the resources, to defend the environment, to defend the earth, to defend our beautiful home now!

环境污染会给生态系统造成直接的破坏和影响，如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害，有时这种间接的环境效应的危害比当时造成的直接危害更大，也更难消除。例如，温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性，往往在污染发生的当时不易被察觉或预料到，然而一旦发生就表示环境污染已经发展到相当严重的地步。当然，环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降，影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊，人们的发病率上升等等;水污染使水环境质量恶化，饮用水源的质量普遍下降，威胁人的身体健康等。严重的污染事件不仅带来健康问题，也造成社会问题。随着污染的加剧和人们环境意识的提高，由于污染引起的人群纠纷和冲突逐年增加。

让我们都来关爱自然，热爱地球吧，手挽手、肩并肩、心连心地铸起一道绿色环保的大堤，捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

Although the world develops much faster and better, the resources on the earth get fewer and fewer.In order to protect them,something must be done.

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.
