茂密的丛林里，有一棵参天大树。

这棵参天大树是小兔、松鼠和喜鹊的家，兔子住在树的底部，松鼠住在树的中间，喜鹊住在枝头上。大树爷爷对她们说：“欢迎你们住在我这里，可你们一定要爱护我呀!”“当然了!”三个邻居都异口同声的保证。

没过几天，兔子为了请客，想把房子装修一下，就把树根掏了许多洞，她想：树这么大，掏几个洞算什么呢?她早就忘记大树爷爷的话了。

又过了几天，松鼠为了准备更多的食物，决定把储藏室扩大些，也忘记了大树爷爷的话，在大树的树干上打了一个很大洞，她想：树干这么粗，我打个洞不会有什么影响的。

初夏，喜鹊快生小宝宝了，为了迎接这些小生命，她打算把窝翻修一下，也把大树爷爷的话忘到九霄云外去了，她折断了许多树枝。她想，大树这么多树枝，我折一点算什么呢?

夏末，一场暴风雨来了，原本强壮的参天大树轻而易举地被摧毁了。兔子、松鼠和喜鹊的家遭到毁灭，她们哭泣着蜷缩在暴风雨中，可后悔已经来不及了。

The snake is a long and thin animal that lives in grass or other dark places.A snake has no legs or feet,but it can move very fast on its stomach.Snakes usually have green,yellow or black skins,which make them difficult for their enemies to find them.Some kinds of snakes live in water.They can swim as freely as fish.

Although people are now said to protect animals, but there are a lot of people wrong-headed, continue to hunt animals, cause many animals to the road to extinction. Humans and animals to see, sold at the same time, made from animal skins coat... But these people ever think, if you are an animal, are hunted by humans, what would you think? Some people say: "Im not a animal." But now hunted animals, animals would like to have? No, never. Although some people know how to care for the animals, but they will only pretending to go to the education of others, and themselves but also damage the environment, killing animals, so enthusiastic tasting animal meat is delicious. Take the puppy around us, for instance, although not a national secondary other rare animals, but also our good partners, whether master how to use it, it still is very dedicated, but humans find dog meat is delicious, began to kill the dog.

Now, some animals have almost extinct, take the crocodile, for instance, although it is very fierce, but humans are more fierce. And in the eyes of human beings, crocodile skin can be made into the luggage, handbags, wallets, shoes and other goods. Because of some organs from animals has the prominent economic value, thus become a subject of human plunder use, become the main factor of extinct animals. So the crocodile, has now become almost extinct animals.

Animal friends, a lot of destruction of human will have serious adverse consequences, ecological environment caused by serious imbalance, so that the human living environment is destroyed. Eliminate animal, is to eliminate human oneself, if one day the animals in the world are gone, that human can survive? To protect animals, cherish this nature of every creature! Let us start from now, to protect animals, make the world a better place!

虽然人们现在都说要保护动物，但是还有很多人执迷不悟，继续猎杀动物，导致许多动物都走向了灭绝的道路。同时人类还拿动物来观赏、卖钱，用兽皮做大衣……但这些人有没有想过，如果你是一只动物，却遭到了人类的猎杀，你会怎么想?有些人说：“我又不是动物。”但是现在人类大量捕杀动物，动物会愿意吗?不，永远不会。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鲜美的肉。就拿我们身边的小狗来说吧，虽然不是国家一二级别的珍贵动物，但也是我们身边的好伙伴，不管主人怎么使唤它，它仍然很兢兢业业，可是人类发现狗肉鲜美，就开始捕杀小狗。

现在，有些动物已经快要灭绝了，就拿鳄鱼来说吧，它虽然很凶猛，但人类更凶猛。而在人类的眼中，鳄鱼皮可以制成行李箱，手提包，钱包，鞋等物品。就是因为有些动物身上的器官具有突出的经济价值，由此成为被人类掠夺利用的对象，成为动物灭绝的主要因素。所以鳄鱼，现在已经成为快要灭绝的动物了。

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，保护动物，使世界变得更加美好吧!

Russian Scientists Surrounded by Polar Bears

俄罗斯科学家被北极熊包围

Relief supplies finally arrived on a remote Arctic island where a group of scientists had been trapped in a weather station. Up to a dozen polar bears had surrounded the station on the island of Troynoy and set up camp approximately two weeks ago. The bears were becoming more aggressive over time, killing one of the stations dogs and breaking a window. On Wednesday, a helicopter that picked up supplies from a nearby vessel arrived with dogs and flares and was able to scare away the bears and allow the researchers to get back to work.

救灾物资终于抵达了偏远的北极岛屿，有一批科学家被困在那里的气象站中。大约两周以前，十几只北极熊将特洛伊诺伊岛(Troynoy Island)上的一个气象站团团包围，并在那里安营扎寨。随着时间的流逝，北极熊变得越来越有攻击性，咬死了气象站的狗，还打破了窗户。周三，一架从附近船只上携带犬和照明弹物资的直升机到达岛屿，能够将北极熊吓走，让科学家正常工作。

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。

那天阳光明媚，老师说了今天要写一篇小动物的作文。我只好来到水族馆参观。一进去就看中了一只小仓鼠，可是爸爸妈妈又不让买，所以我只好每隔一段时间去看它。

三个月前，这只小仓鼠小巧玲珑。现在，已经有我的拳头这么大了呢！这只可爱的小仓鼠，胖胖的小手小脚几乎都看不见了，五官也都挤在了一堆，真像个憨态可掬的小宝宝。它的身上没有一处不是毛茸茸的，像小丑杂耍时的一个小球。小仓鼠身上还有着独特的黑白条纹，像一只诙谐的迷你。它行动敏捷，活泼好动，又像个淘气的小孩。

有一次，我去看它。它被老板放出来自由活动。它一会躺在椅子上，晒日光浴；一会儿和另几只小仓鼠一起躺在舒适而又温暖的干草上窃窃私语。后来，它渐渐地注意到了我。原本，它只站在我的跟前仔细地打量着我。慢慢地它见我没有恶意，便友好地爬到我的小手上，挠挠了我的手掌心，似乎在跟我握手问好呢。“你好，我是一只爱交朋友的小仓鼠，你愿意和我交个朋友吗？”我不知不觉的笑了。

从那以后，我便天天去看它。每当我看到这只小仓鼠时，心里就会有一种说不出来的快乐。我不禁想到：人类和动物竟然也能用有这么深厚的感情！所以，我要呼吁大家：“快跟小动物们交朋友吧！”

animals are natural resources that people have wasted all through our history. animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. thousands of kinds of animals have disappeared from the earth forever. hundreds more are on the danger list today. about 170 kinds in the united states alone are considered in danger.

why should people care? because we need animals, and because once they are gone, there will never be any more.animals are more than just beautiful or interesting. they are more than just a source of food. every animal has its place in the balance of nature. destroying one kind of animal can create many problems. for example, when farmers killed large numbers of hawks, the farmers` stores of corn and grain were destroyed by rats and mice. why? because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

luckily, some people are working to help save the animals. some groups raise money to let people know about the problem. and they try to get the governments to pass laws protecting animals in danger. quite a few countries have passed laws. these laws forbid the killing of any animal or planton the danger list. slowly, the number of some animals in danger is growing.

“汪!汪!汪!”大家都知道这是什么动物了吧。这是人类最忠实的朋友_狗。我最喜欢的动物就是狗了。

我家曾经养过一条狗，叫灰灰。灰灰有一张可爱的面孔，上面还嵌着一对闪闪发光的小眼睛，身上是灰色的毛，像地毯一样光滑。一条短短的小尾巴，总是摇来摇去，显得很可爱。

灰灰吃食物时，总是先用舌头舔一下，然后，东望望，西望望，没人在时才吃起来。偶尔，还会发出汪、汪、汪的声音，像是在说:“真好吃。”

灰灰睡觉时，总是把身体缩在一起，发出汪汪的声音，我想应该是想妈妈了。灰灰从小就离开了妈妈，真是可怜，我想把灰灰送回家去，可又舍不得，你说我该怎么办呢?

为了不让灰灰寂寞，我经常带它出去散步、做游戏。灰灰一出门，就围着我不停地跑，一会儿把爪子趴在我脚上，一会儿又吐吐舌头，东望望，西瞧瞧，显得很高兴。

我爱小狗灰灰。

Nowadays more and more people keep animals as pets; they treat them as their family members. But there is someone who likes to torture animals. They do this for some reasons: they don’t like animals, they get fire or they are just not happy. Some people think it’s fine to torture animals, because people are suffering more pressures than before; they need some way to be relaxed. In my point of view, I think animals deserve better.

In the first place, some animals are kept as pets in family. They are a part of it, like dogs or cats. They can bring people happiness. Lost of parents have pets for the reason that it could help their children learn to care about others; they think it’s a good way to teach children to be a good person. For the single people, pets could be a good companion, especially for an introvert, they prefer to talk to an innocent animal better than a person who is wearing a mask.

In the second place, people who are like to torture animals may have some psychological problems. If someone is suffer too much pressure that they couldn’t breath, they should find a healthy way to release it, for instance, they could go to swimming, jogging or climbing. They don’t have to hit pets to release their anger. Some people even cut pet’s ear or claw or had pet’s eyes gouged out. This is really sick; it’s hard to understand that what kind of people would hurt an animal when they are look into their innocent eyes.

In sum, animals is a lovely creature that made by god to bring happiness to human beings. People should treat them better than torture them.

现在越来越多的人把动物作为宠物,他们对待他们的家庭成员。但有喜欢虐待动物的人。他们这样做有一些原因:他们不喜欢动物,他们得到火灾或他们只是不开心。一些人认为它很好折磨动物,因为人们的痛苦比以前更多的压力,他们需要一些放松的方法。在我的观点,我认为动物应该得到更好的。

首先,一些动物作为宠物饲养在家庭。他们是其中的一部分,像狗或猫。他们可以给人们带来幸福。失去父母的养宠物的原因,它可以帮助他们的孩子学会关心别人,他们认为这是一个好方法教孩子成为一个好人。单身人士,宠物可能会是一个好伴侣,尤其是对于一个内向的人,他们更喜欢跟一个无辜的动物比一个戴着面具的人。

第二,喜欢虐待动物的人可能会有一些心理问题。如果有人受到太多的压力,他们无法呼吸,他们应该找到一个健康的方式来释放它,例如,他们可以去游泳,慢跑或爬山。他们没有达到宠物释放自己的愤怒。有些人甚至把宠物的耳朵或爪或宠物的眼睛剜了。这是真的病了,很难明白,什么样的人会伤害动物当他们看着他们的无辜的眼睛。

总之,动物是一种可爱的动物,由上帝给人类带来幸福。人们应该对待他们比折磨他们。

Many animals are in danger of dying out.As is shown in the chart， we can see the number of animal species decreases faster and faster and this trend will continue.From 1980 to 2010， at least 1 million animal species have disappeared.Worse still， more and more wild animals are in great danger.It is not a piece of sensational news; it is a fact， a harsh reality.Unfortunately， we may not see these animals in the near future。

From the second picture， we can find some reasons.Why is the number of animal species declining year by year? Apparently animals have bee victims of fashion industry.Animal skin has been used to make fashionable clothes and these clothes sell at a high price.So some greedy people begin to kill animals in a large quantity.This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings。

As far as I am concerned， something must be done to stop this illegal action.We believe "no buying， no killing".First， we must make concerning laws to protect these animals in danger.Second， we must take some measures to protect animals effectively.Animals are our friends and part of our environment.Third， we should raise peoples awareness to protect animals and our environment.In this way， we can build a harmonious society and ensure a sustainable development。

我最喜欢的小动物是小白兔，因为小白兔纯洁、温柔、可爱。

小白兔长着一身洁白的绒毛，从远处看，就像是下了一层雪，真是美丽极了！小白兔的眼珠和别的动物比起来不太一样，别的动物的眼珠都是黑色的，而小白兔的眼珠是红色的，像是镶嵌了一颗红宝石。小白兔有三瓣嘴，吃起东西来可快了。

小白兔喜欢吃青菜、白菜和萝卜。有一次，我逗小白兔，故意拿了一条鱼给它吃，它闻闻后走开了，嘴里还发出了声音，好像在说：“我是兔子，又不是猫，我不要吃鱼。”我急忙把鱼换成了青菜，它这才高高兴兴地吃了起来。

小白兔很爱干净，但它一点都不爱护家。随地大小便、把青菜弄得哪儿都是，唉，还有打扫，真麻烦！

记得它第一次来到我家，十分胆小，长天躲在笼子里不出来，只有我们走后，才出来溜溜，渐渐地，我们熟了，经常在一起玩儿。

我爱我家的小白兔，你们喜欢吗？

我现在最喜欢爬树的小猴子。因猴子爬树时会荡来荡去，像荡秋千一样，还会咯咯咯地笑，它还有红通通的小屁股，我觉得超可爱。

小猴子还会吃水果呢！你可能会问我：“谁还不会吃水果呀？”我的回答是：“动物会吃水果不稀奇，但是它吃起来可不一样呢！”猴子吃水果可好玩了！要剥皮的剥皮，要吐核的吐核。它吃桃子的时候，两只手抱着桃子左一口右一口，上一口下一口，直到把桃子吃完了才把桃子核丢了，吃得可干净了！

猴子爬树可厉害了。双脚踩住一棵树的树枝，两只手抓紧了另一棵树的树枝，然后纵身一跳就到了另一棵树上，轻轻松松，还会给游客一个得意的眼神呢！

我觉得猴子吃水果就像人类一样厉害，爬树则比人类厉害多了，应该是动物世界里数一数二的攀岩高手了吧！

There used to be many kinds of birds which are pests for protected crops. They are good friends at present.But the number of the birds has been greatly reduced because too much poison is used. As the result, the numberof the pests has increased.The peasants spent a lot of money and time in killing them every year.But it is still hard to eliminate them.Now you can see how poor it is for us to protect wild animals and to keep the balance of nature.Only that everyone know these can we live on a beautiful lives.

曾经有许多鸟类都能够保护庄家，以防害虫的侵害。他们是农民的好朋友。但是鸟类的数量正在急剧减少，这是因为人们大量使用农药造成的。所以，害虫的数量增加了。每年，农民都会花费大量经费，以及时间来消除害虫。但是，人们还是很难将它们清除。如今，我们无法保护野生动物，并无法保持生态平衡。只有我们所有人提高意识我们才能过上幸福的生活。

大家肯定有最喜欢的小动物吧？想知道我最喜欢的动物是什么吗？没错，就是它——小兔子。

它有两只修长的耳朵，毛茸茸的可爱极了，真是让人见了就喜欢。两颗火红的小眼睛活像两颗光芒璀璨的红宝石，镶嵌在它那可爱的小脸蛋上。一只小巧玲珑的鼻子端正的长在脸蛋的正中间，可灵敏了。一张三瓣嘴里有两颗大大的门牙，吃起胡萝卜来咯吱咯吱的，几秒钟就啃完一根胡萝卜了。你说快不快？它全身雪白远看像一堆棉花堆放在那里，近看像穿了一件白色大衣。

有一次我在它很远的地方放了一根大大的胡萝卜，以为它根本看不见。可没想到的是正在呼呼大睡的它感觉有一股很香的气味扑鼻而来，于是一下窜起来用它那灵敏的鼻子仔细闻，笑了笑点了点头，好像在说：“是胡萝卜。”于是它就像离弦的箭一样冲了出去，不一会儿就找到了我放在那儿的大胡萝卜，拿起大胡萝卜就开始津津有味地咯吱咯吱的吃了起来。我在旁边都垂涎欲滴了，没想到小兔子的鼻子都能闻到那么远的东西，跑的那么快，真是让人惊讶不已呀！

看这就是我最喜欢的小动物，它多可爱啊！你是不是也喜欢它了呢？

我喜欢许多动物，要说最喜欢的，就是奶奶家的猫了。

这只小花猫长着圆圆的脑袋，大大的眼睛，三角形的耳朵，黑白相间的花纹，它有着胖胖的身子，一条长长的尾巴，还有四只灵活的爪子。

我喜欢逗小花猫玩，小花猫也喜欢和我做游戏。有一次，小花猫正在睡懒觉，我悄悄地走到它的跟前，凑在它的耳边大叫一声，小花猫吓得“蹭”得一下跳出去老远，一溜烟似的逃跑了。我哈哈大笑，小花猫看见是我，它又跑了回来。还有一次，我用一根小木棍挑逗小花猫的胡子，小花猫跳起来又抓又咬，随着我的木棍上蹿下跳，它真像一个无畏的勇士。有时，我还背着奶奶，偷偷地喂小花猫一些火腿啊什么的东西，渐渐地我们就成了最好的好朋友了。

每次从奶奶家回来，小花猫也总是把我送出门外，望着我们远去。小花猫喜欢我，我更喜欢小花猫。

导语：人类正试图猎取野生动物以获取更大的利润，下面是yuwenmi小编为大家整理的优秀作文，欢迎阅读与借鉴，谢谢!

As is often read in the newspaper reports, wild life especially the rare species is threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit., which, of course, results in a sharp decrease in the number of animals. So it is high time for us to take quick action to protect them. First of all, its quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of responsibility. People will surely take it for granted to have the duty to prevent any killing of wild animals. So a national publicity campaign should be launched, thus giving animals a good living environment. In addition, the government should pass some laws to forbid any hunting of rare animals. We dont expect anything harmful to wild life to happen again.

If everyone is involved in the protection of wild life, were sure man will be a good friend of animals rather than their enemy.

【参考译文】

正如报纸上经常看到的那样，野生生物特别是稀有物种面临灭绝的危险。人类正试图猎取野生动物以获取更大的利润，当然，这会导致动物数量急剧减少。所以现在是我们采取行动保护他们的时候了。首先，每个公民意识到保护动物的重要性是很有必要的。只有认识到它的重要性，人们才能产生责任感。人们一定会想当然地认为有责任阻止野生动物的捕杀。开展全国性宣传活动，为动物创造良好的生存环境。此外，政府应该通过一些法律，禁止猎杀珍稀动物。我们不希望发生任何对野生动物有害的事情再次发生。

如果每个人都参与野生动物的保护，我们相信人类将是动物的好朋友，而不是敌人。

哥哥家养了一只小狗狗，因为小狗长得很壮实，所以哥哥给小狗狗取名叫“肉肉”。我最喜欢的小动物那就是小狗。

肉肉长得非常漂亮，人见人爱。它全身长着黑色的皮毛，那条翘着的小尾巴，总是不停地摇来摇去，那双水晶似的大眼睛，总是充满着好奇，不停地到处张望。

有一天，我去哥哥家玩。一到门口，肉肉就站在门口迎接我，我就扮着鬼脸想去摸它，肉肉吓得立即逃走了。晚上，我和哥哥在床上玩游戏，肉肉走过来，把头放在床边，哥哥就帮它按摩，还用梳子梳理着它的毛发。肉肉很通人性，不停地摇摆着小尾巴，好像在说：“谢谢小主人，谢谢小主人。”。

因为肉肉，我更喜欢去哥哥家玩了。

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友，人们应该善待它们，但现在，中国和世界上的许多人为赚钱而捕杀动物。众所周知，中国有许多珍稀动物，如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋，或是为了食用它们的肉。

结果大量的珍稀动物死亡了，真可惜呀!

目前，我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们：也捐款来支持保护动物的活动，如，有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物，因为自然就像一个大家庭，人类和动物必须和平共处：我们必须保持生态平稳。

如果人类能这么做，这个世界就会越来越好。

春天到了，青蛙又开始“呱呱”地唱歌了，我发现又有人在田野里开始捕捉青蛙了，使青蛙成为那些人的“盘餐中”，我感到非常痛心。

Spring has come, the frog began to "Gua Gua" to sing, I found someone in the field began to catch frogs, the frog became those who "tray", I feel very sad.

青蛙是动物世界中最出色的“庄稼的保护神”。它头上那两只圆而突出的眼睛，能让它看清庄稼天敌，但捉害虫全靠它又长又宽的舌头，舌根长口腔的前面，舌尖向那么一伸，快速地伸长长的舌头，一下子把害虫粘住，然后吃掉。青蛙的背上有绿色的深色花纹，腹部是白色，能帮它逃脱天敌血盆大口。身体下面有四条腿，前腿短，后腿长。青蛙是两栖动物，不仅能在地上跳，而且也能在水里游。

The frog is the best protection of God in the animal world "crops". Its head the two round and protruding eyes, can let it see the crops of natural enemies, but to catch insects depend on it long and wide front long tongue, tongue in oral cavity, the tip of the tongue to then extend, rapid elongation of long tongue, all of a sudden the vermin stick, and then eat. The frog is green dark pattern on the back, abdomen is white, can help it escape predators jaws. Has four legs, the body below the forelegs are short, long hind legs. Frogs are amphibious animal, not only on the ground to jump, but also can swim in the water.

青蛙吃苍蝇，蚊子，蝗虫，小飞娥等害虫，一天大约能吃掉120只，半年下来就能吃掉15000只，这是多么大的功劳哇!就连青蛙的幼虫 ------ 蝌蚪也能消灭许多害虫哩!真不愧“庄稼的保护神”，农民伯伯的好助手呀!

Frogs eat mosquitoes, flies, moths and other insects, locusts, a day can eat only about 120, six months down can eat only 15000, this is how big a contribution wow! Even the frogs, tadpoles can also destroy larvae of many of the pests miles! Really deserves to be called "the crops the protection of God", farmers uncle a good assistant!

从现在开始，我们一起保护“庄稼的保护神”------ 青蛙吧!让我们共同保护[动物]生态平衡!

From now on, we work together to protect the "protection of God" crops - frog! Let us work together to protect the ecological balance [animal]!

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。
