环境保护问题英语作文篇一

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. First, 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.

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

As we all know,animals are our friends.I like every animal.But I like dogs best.Dogs are not only very lovely,but also very helpful.Thats why we all feed dogs at home.I often share happiness and shorrow with it, which belongs to me three years ago,called"Betty".In other words,we should treat them as our real friends.Do you agree with me?

我们都知道,动物是我们的朋友。我喜欢所有的动物。但我最喜欢狗。狗不仅是很可爱,但也很有帮助。这就是为什么我们都喂狗在家里。我经常和它分享快乐,我三年前称它为“贝蒂”。换句话说,我们应该善待我们的真正的朋友。你同意我吗?

前几天我嚷嚷着让爸爸给我买鱼，他答应了。我们来到一个叫“海洋一族”的水族馆。

The other day I yelled for my father to buy me fish, and he said yes. We came to an aquarium called "marine family".

哇！好漂亮呀！我惊呆了，这里的鱼各式各样，有：热带鱼、野鱼苗……爸爸给我捞了七条鱼。有两条红色，两条黑的，三条花花的。我高兴地把它们带回了家。一到家，我就迫不及待地把它们放进鱼缸，并给它们喂了鱼食。

Wow! How beautiful! I was shocked, fish here are varied, including: tropical fish, wild fry...... My father fished me for seven fish. There are two red, two black, three huahua. I took them home happily. As soon as I got home, I couldnt wait to put them in the fish tank and fed them fish food.

就在第二天早上，鱼竟然死了三条，我十分伤心，爸爸安慰我，“没关系，别伤心。”听了爸爸的话，我的心情渐渐平静了下来。

On the morning of the second day, the fish died three, I was very sad, my father comforted me, "never mind, dont be sad."." After listening to my father, my mood gradually calmed down.

过了几天，剩下的四条鱼还活着，它们保持着旺盛的精力，游戏时它们摇头摆尾，舞动着鱼鳍。在水里欢快的游着。我给它们喂食的时候，它们总是争先恐后的抢食物，你追我赶。尤其是那条大金鱼，它非常霸道，另外三条小金鱼见了它，有些畏惧，总是小心的去吃食。

After a few days, the rest of the four fish alive, they maintained the exuberant energy, the game they yaotoubaiwei, waving fins. Swimming happily in the water. I to feed them, they always fall over each other to grab food, race each other. Especially the big goldfish, it is very overbearing, and the other three little goldfish see it, some fear, always careful to eat.

我很喜欢这几条小金鱼，我会好好爱护它们，并把它们喂养的更加健康，直到它们慢慢长大。

I like these little goldfish very much. I will take good care of them and keep them healthier until they grow up.

[我喜欢的动物英语作文及翻译

一天，我到集市去，忽然听到一位老爷爷高声喊道：“卖青蛙喽!卖青蛙喽!活蹦乱跳的青蛙。”接着就听见几声凄惨的蛙鸣，我顺着声音走过去，只见几只青蛙被老爷爷用一根绳子绑在一起，前脚向外伸着，想逃脱。可总是被老爷爷拉出去，竹篓里也装着青蛙。老爷爷眼里是大把大把的钞票，而不是满天乱飞张牙舞爪的蚊子。我望着这场面，听着惨叫，我的心不禁揪紧了。

青蛙的本领很多，它能预报天气，我国有不少的农谚也是反映蛙鸣雨天气的关系的，如“雨后蟾蜍叫，不久大雨到。”青蛙还是捕食昆虫的健将，当青蛙尚处在幼虫的时候，它一天就能吃掉一百多只孑孓，而长大成蛙后，用它灵巧的舌头，平均每天可吃掉七十多只害虫。青蛙还能预报丰收，南宋诗人辛弃疾在西江月中写道“稻花香里说丰年，听取蛙声一片”。

我们学过《狼与鹿》一课，人为了保护鹿却过渡的捕杀狼，鹿成破坏森林的祸首，是鹿和凯巴伯森林走向灭亡。这篇课文告诉我们：自然界的各种事物是密切联系的，不能随意破坏生态平衡，不然会产生无法想象的后果。卖青蛙的老爷爷您想想吧：如果您抓了一只青蛙，就会放掉七十多只害虫，难道您想看到漫天耀武扬威的蚊子和被蚊子咬的遍体鳞伤的我们吗?

人类啊!快醒醒吧。不要让害虫再猖狂了!我提出倡议：让我们和动物和平共处，保护人类的好朋友—青蛙吧!

Dear Lily:

I think you had better feed a hamster,the trediest kind of pet these days is the small hamster. People like them because they are quiet and clean. I have a hamster named Tom,it’s very cute and easy to take care of,and it’s cheaper than rabbits or cats,so I bought it. She’s my best company,because she reads books and litens to music with me every night.However,life with a hamster isn’t always perfect,she sometimes noisy at night ,she love sleep all day,too. So,sometimes she is very boring! How do you think?

人与动物的关系是密切的。我们曾经学过《珍珠鸟》这篇文章，它主要讲述了作者精心饲养珍珠鸟，与它们建立了深厚的友谊。

这篇文章字里行间都流露着作者对珍珠鸟的喜爱之情。人和动物是好朋友，仿佛在千百年前就有了，这感情是无比深厚的。我还记得一个片段的大概内容：作者让珍珠鸟栖息在幽林似的环境中，而且不去打扰它们。《珍珠鸟》的作者不像其他养鸟者那样，只是为了欣赏鸟儿那色彩斑斓的羽毛，倾听鸟儿那美妙动听的歌喉，就让鸟儿成天生活在惊恐中。

某些家长把鸟儿买回来，放在笼子里，然后就对孩子们说：“这是给你们玩的!”孩子们就会听着他们的话对着鸟笼又踢又打，把木棍伸进笼子里挑弄鸟儿，促使让鸟儿惊恐地飞来飞去。大人们不但不加以阻止，还要拍手叫好。鸟儿本来是自由的，如果让那些养鸟人为鸟儿设身处地地想一想，也许他们就知道怎样做了。 还有一个令我记忆犹新的片段：珍珠鸟雏儿在作者伏案写作时，扒在作者的肩上轻轻地进入甜美的梦乡。

我读着，仿佛正亲眼看见这只雏鸟正甜美入睡的情景，眯着眼睛，多么可爱! 相比之下，现在，许多猎人为牟取暴利，去捕杀人类的好朋友，大熊猫、孟加拉虎、非洲象……濒临绝种的原因，就因为它们拥有了人们渴望拥有的美丽的皮毛、洁白坚硬的象牙!在一场场模特表演上，模特儿们披着貂皮大衣，穿着鳄鱼皮鞋，戴着松鼠毛领巾，一转身，迎风摆动的不但是动物的生命，还有血腥!捕杀动物!这是多么丧绝人性的行为!这还是人吗?简直是禽兽! 千百年前，动物是人类的朋友。

我希望从今以后，动物和人类永远和平共处，世世代代，永远是最好的朋友!

In modern society, we tend to become more and more aware of our living environment or physical environment, because we are not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go.

Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keeps for many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

在现代社会中,我们往往更加了解我们的居住环境还是自然环境因为我们不干净如故.现在这么多人选择它作为自己的房子,而不是它的位置和环境费用负担.众所周知,环境污染日趋严重,这些年来,我们可以做的是努力保护环境,逐步实现.至于政府的污染,为百姓.我们也设法保护它,使之保持清洁.虽然我们已能在一定程度上保护环境.它还有很长一段路要走.

保护我们的环境 地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤。大多数都是包装大部分垃圾变成土而不是塑料制品,塑料保持多年来它会污染我们的环境,所以我们不应该浪费我们应当做些事情回收利用。

Marine biological environment is a complex system including sea water, sea water, soluble matter and suspended matter, seabed sediments and marine organisms. The rich biological resources, mineral resources, chemical resources and power resources in the sea are indispensable human resources treasure houses, which are closely related to the survival and development of mankind.

At present, the main objective of marine conservation is to protect marine biological resources so that they can not be exhausted for sustainable use by mankind. In particular, priority should be given to the conservation of marine animals that are valuable and endangered. According to the UN investigation, due to overfishing, mangrove accidental killing of non target to allow the killing of marine organisms, the coastal engineering construction, deforestation, pollution of the marine environment in general, at least 25 of the worlds most valuable fisheries resources consumed, whales, sea turtles, manatees and many other marine animal faces the danger of extinction. It is expected that with the expansion of marine development, it is possible to cause more damage to marine biological resources.

Marine protection task should first stop on the marine biological resources excessive use, secondly to protect the marine biological habitat or habitat, especially their migration, spawning, feeding, avoid Huahai coastline, beaches, estuaries, coral reefs, to prevent heavy metals, pesticides, oil, organic produce and eutrophication. Nutrients such as marine pollution. Maintain the ability of regeneration of marine biological resources and the natural purification ability of the sea water, maintain the marine ecological balance, and ensure the sustainable development and utilization of the marine.

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗 没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!

我非常喜欢《我的野生动物朋友》这本书。它是1990年出生于非洲的法国小女孩蒂皮写的。蒂皮从小跟拍摄野生动物的父母在丛林里长大，与非洲野生动物和当地土著人生活在一起。

她非常喜爱野生动物朋友们。用她自己的话说：“我呢，爱鸟爱得不得了。我说爱得不得了，一点儿也不夸张，因为它们就像我的兄弟姐妹一样。这也没有什么出奇的，因为我就在它们当中出生，长大。非洲的野生动物是我最早的朋友，我对它们了解得可清楚了……”

蒂皮说：“我真不明白，人类为什么要杀死野生动物，真是荒唐极了……”是啊，野生动物并非是我们的敌人，而是我们不可缺少的好朋友。我们人类为什么要伤害它们呢 听说，有些地方的猎人为了更容易地捕杀森林中的猎物，不惜烧毁森林，杀死被烈焰逼得惊慌失措的动物。这样一来，不久以后，原本的森林就会变成了一片沙漠;还有些偷猎者猎杀国家保护动大熊猫、东北虎、藏羚羊和猎豹，只是为了用它们的皮毛换些钱……这样的事例还有很多很多。

当然，也不是所有的人都像刚才所说的那些人一样，现在有了动物保护协会，而且也有不少有爱心的人经常救助和收养一些动物。这样一来，就有不少动物得到了保护。

不管怎样，我希望大家都来保护动物。动物也是有感情的，它们受到人类的伤害也会伤心。而且地球不光是人类的，也是动物们的，它是我们人类和动物们共同的家园。我们没有权利夺走动物们的自由，动物们的家园。我们应该尊重每一个生命，保护动物就是保护我们自己。

Not only we humans upon earth, there are lots of animals. Humans and animals are good friends, so we need to protect animals. There are many animals are endangered in the world, such as the giant panda, Chinese sturgeon, manchurian tiger, and so on. However, my favorite animal is the highest level of protection in our country.

Because of his long fat, very cute. The giant pandas main food is bamboo. But because people cut down trees, the giant panda food less and less, so we should protect trees. There are some animals, because they do not adapt to the environment, is nearly extinct. So we need to protect the environment, love the nature. Let us and animals can live harmoniously in the earth. Students, animal is priceless to human nature, is our friends of human beings. Their life is closely related to our life.

The mass extinction of animals can cause serious ecological imbalance, so that our human living environment is destroyed. Lets start from me, start from now, to protect animals. Let the world a better place!

地球上不只有我们人类，还有许许多多的动物。人类和动物是好朋友，所以我们要保护动物。世界上有许多动物都濒临灭绝，比如说大熊猫、中华鲟、东北虎等等。然而，我最喜欢的动物就是我国一级保护动物大熊猫。

因为他长的胖胖的，很可爱。大熊猫的主要食物就是竹子。但是由于人们砍伐树木，使大熊猫的食物越来越少，所以，我们要保护树木。还有一些动物，因为不适应环境，已经快要灭绝了。所以，我们还要保护环境爱护大自然。让我们和动物能够和谐地生活在这个地球。同学们，动物是大自然给人类的无价之宝，是我们人类的朋友。它们的生死与我们的生活息息相关。

动物的大量灭绝会造成生态的严重不平衡，从而使我们人类的生存环境遭到破坏。让我们从我做起，从现在做起，保护动物。让世界变得更加美好吧!

我不希望我的祖国是垃圾国家，任凭白色垃圾到处肆无忌惮，我多么希望我的祖国是一个美丽而干净的，这就需要我们保护环境，哪怕捡起一张纸，也能为祖国增添一点色彩。

星期二的早上，天空格外的蓝，空气也格外的清新。我的心情特别的好。我早早的跑到广场锻炼身体，我跑着跑着，“沙，沙......”咦!什么东西在我后面跟着，我猛一回头，定睛一看，原来是一团皱巴巴的纸团，在我身后当起我的小尾巴。不远处的几个垃圾在微风的吹拂下，在广场上你追我赶，像赶集似的。花坛处的两个叔叔正在边说边吃，还边扔垃圾，我的心头顿时涌上一股怒火：“哼!等着瞧!一会儿我就让你哑口无言。”我三下五去二，不一会就把垃圾捡到手，我抬起头看到清洁工老爷爷正在扫垃圾，我跑过去把垃圾放进爷爷的袋子里，老爷爷愣了一下，随后就笑了，低下头嘴里不住地说：“好孩子呀!好孩子。”我又捡了些垃圾，放进老爷爷的袋子里，老爷爷微笑的说：“哎呀!孩子，你不怕别人说你是捡垃圾的?”我笑了说：“我不怕。保护环境是我们应该做的。”这时，花坛处的两个叔叔停止了说笑，都张口结舌：“恩.——这个......”我得意地把眉头一挑，向家走去。温暖的阳光照在我身上......

祖国的清新美丽需要我们每一个人行动起来，保护环境，从我做起!请从弯腰捡起一片纸开始。

In order to support Beijing to hold the 2008 Olympic Games and protect our environment,an activity was organized by the Young League and Students Union of our school during the week from June 3rd to June 8th.

All the students in the senior grades took active part in it.Some students cleaned the playground,watered the young trees and flowers,and removed weeds.Some students collected waste paper,old books,empty cans and old toys.They had them sorted and sent them to the recycling center.

The activity is really instructive.Now we all have realized how important protecting the environment is.

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!

我们要保护小动物，特别是小鸡这类弱小的动物，因为小鸡早晨可以叫我们起床，可以生一个又一个圆圆的的鸡蛋，还可以提供鸡肉给我们吃。

We need to protect the small animal, especially this kind of small animal chicken, because chicken morning to wake us up, can have a round egg, can also provide for us to eat chicken.

有一次，我和妈妈上菜市场，听见一位老奶奶在喊：“卖鸡了，今天的鸡又肥又嫩!”妈妈说：“今天，我们买一只鸡回家，炖汤喝。”我说：“好吧。”可又想了想：如果我们吃了鸡，那么就吃不到鸡蛋了，就对妈妈说：“不行，吃了鸡就没有鸡蛋吃了。”“傻孩子，你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡，只见她拔下鸡脖子上的毛，拿刀用力地在鸡脖子上划了几下。血喷向了四周，鸡挣扎了几下就死了。“太残忍了，我不要吃鸡!”我向妈妈大声的抗议。“好吧，不买了，我们就去买点蔬菜吧。”也许妈妈也觉得残忍，就同意了。

One time, my mother and I heard the food market, an old woman shouted: "chicken, chicken fat and tender today!" Mother said: "today, we bought a chicken soup to drink at home." I said: "OK." But think again: if we eat chicken, so cant eat the egg, the mother said: "no, not eat chicken egg to eat." "Silly boy, what do you care ah!" Mother allowing no explanation to put me into the chicken. The old woman was a chicken, she pulled out the hair on the neck, a knife in the neck with a few strokes under. Blood sprayed around chicken, struggled and died. "So cruel, I dont eat chicken!" I asked my mother loudly protested. "Well, do not buy, we went to buy some vegetables." Maybe mom was cruel, also agreed.

假如我们的生活中没有了动物，世界就会变得很孤独。我们要保护动物，从自身做起：少吃肉类食品，少穿皮衣毛衣;看见别人欺负动物，要勇敢地站出来劝说他们。

If we live without the animal, the world will become very lonely. We must protect the animal, start from their own: eat less meat, less wear fur sweaters; see others bully animal, we should stand up to persuade them.

保护动物，人人有责!

Animal protection, everyones responsibility!

My favourate animal is tiger,because tiger is very strong and powerful,it is the king of the forest.Tiger looks handsome as well, the skin has two corlors:yellow and black,and they are both my favourate colors.

I like tiger,and the year 201X is just the Chinese tiger year.I hope all the people will keep healthy,just like tiger.

导语：现如今很多学生都戴着厚厚的眼镜，我们应该注意视力的保护，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

When I was in primary school, my parents told me I must keep my eyes not so close from the book, or I would become ugly. I keep it all the time, now so many years have passed, I find most of my classmates have worn glasses, while I not one of them. Thanks to my parents, I keep the good eyesight now.

【原文翻译】

当我上小学的时候，我的父母告诉我必须要保持眼睛不要离书本那么近，不然我就会变得丑。我一直记得他们的话，如今多年过去了，我发现大部分的同学都戴上了眼镜，而我没有戴。多亏了父母，我现在的视力保持得很好。

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。

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。

The kitten in my mind has always been the most lovely animals, just my house downstairs there is a kitten, I like it very much.

Kitten has a football like face, with above two small pointed ears, a small nose is small. The kittens eyes narrowed into a crack during the day, but at night with big, round, still shining with green light.

Kitty likes to jump up. It is the long tail to keep the balance for it. Cat meat pad to make it under your feet start to quietly, brought a lot of convenience to catch mice.

Cats like to collect some interesting things it. So in its nest can often find little wool ball, feather.

Kittens sleep with your eyes closed, curled up the legs and tail, appear very quiet.

Oh, cute kitten, I like you!

小猫在我心目中一直是最可爱的小动物，正好我家楼下就有一只这样的小猫，我非常喜欢它。

小猫有一张橄榄球似的脸，上面竖着两只尖尖的小耳朵，一个小巧玲珑的鼻子不大不小。小猫的眼睛白天眯成一条缝，可到了晚上就睁的又大又圆，还闪着幽绿色的光芒。

小猫喜欢上蹿下跳。它那条长长的尾巴为它保持了平横。小猫脚底下的肉垫让它走起路来悄无声息，为抓老鼠带来了不少方便。

小猫喜欢收集一些它觉得有趣的东西。所以在它的窝里还经常能找到毛线球、羽毛之类的小东西。

小猫睡觉的时候闭着眼睛，蜷着腿，缩着尾巴，显得十分安静。

小猫的嘴非常的馋。一次，我拿着香肠经过，它立刻目不转睛地盯着我，好像在说：“给我一点香肠吧!”看着它这副可怜巴巴的样子，我想了半天，最后终于还是给了它一半。它马上躲到一边，津津有味的吃起来。

啊，可爱的小猫，我喜欢你!
