As a matter of fact, a great number of animals and plants had extinct. All this was substantially because of we human being. And a large number of them are endangered.

There is no denying the fact that keeping pets is a hotly debated topic today. Some people claim that keeping pets is a good thing to do. They believe that pets, like cats and dogs, can help relieve the loneliness suffered by senior citizens and other social members who are confined to their homes for this reason or that. They also argue that keeping pets helps mankind understand animals world and develop positive feelings toward them.

有一个不可否认的事实,即养宠物是当今一个被热烈讨论的话题。有的人认为养宠物是一件好事。他们认为宠物,比如猫和狗,有助于缓解年长者和那些由于这样那样的家庭原因限制的社会成员的孤独感。他们还认为,养宠物有助于人类了解动物世界,培养对它们的积极态度。

Others, however, hold the opposite view. They regard keeping pets as a useless but harmful thing to do. Firstly, pets can transmit diseases. Secondly, the noises and dung of pets are sources of pollution. Last but not least, as many rare birds and animals are kept as pets, they will surely be hunted on a large scale, which means a threat to the balance of the ecosystem.

然而,其他人持相反观点。他把养宠物当做是无用而且有害的事。首先,宠物可以传播疾病。其次,噪音和宠物粪便是污染的来源。最后,许多珍禽异兽作为宠物饲养,他们一定会被大规模猎杀,这意味着威胁到生态系统的平衡。

Weighing the arguments of both sides, I am inclined to agree with the latter. Anyway, we can lessen our loneliness and express our love toward animals in other ways. And it is my beliefs that only by placing man and other species on an equal basis can us expect to have a lively and colorful world.

权衡双方的论据,我更倾向于同意后者。不管怎么样,我们可以通过其他方式来减少我们的孤独和向动物表达我们的爱心。我相信,只有在人类和其他物种平等的基础上,我们才能期待有一个生动多彩的世界。

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 become 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。

This afternoon, I turned on the computer on the qq, and saw in qq space "simply make the gods cry".

Some people are ready to take the little bears bile. At that time, break the cage, a mother bear with huge PAWS strangled little bear, then her head hit the wall and died. Maybe it is their best way to them, because they are relieved.

After I read this story, I almost cry. So cute teddy bear, so the great bear, who is cruel killed them? Is human. Who is the one who claim to protect giant pandas? As humans. This is not a contradiction? The giant panda is a national treasure in our country, but as soon as I saw some pandas humans want to flee. Why is this? Because someone hurt the panda.

The panda is so cute! They also have life, they are not rich. We must protect the panda, some panda has been found, there are some pandas still suffer from the endless pain. We want to be treated, if they are they, by this pain?

Here, I appeal to everyone: love animals, let animals no longer afraid of us, let the world become real peace!

At the same time I also urge those who hurt the panda: panda also have life, pandas have feelings. Their value is not let us make a living, but live for yourself. I hope you can stop here!

今天下午,我打开电脑上了qq,,在qq空间里看见了“惊天地泣鬼神”的一幕。

一些人准备取小熊的胆汁,这时,一只母熊挣脱了铁笼,用巨大的熊掌掐死了小熊,然后把头撞上墙壁,死了。也许这是它们最好它们的办法,因为它们解脱了。

看完这一则故事,我快哭了。这么可爱的小熊,这么伟大的母熊,是谁狠心夺走了它们的生命?是人类。口口声声说保护大熊猫的是谁?也是人类。这不是自相矛盾吗?大熊猫是我国的国宝,可一些熊猫看见人类就想逃。这是为什么?因为有人伤害熊猫。

熊猫是多么可爱啊!他们也有生命,它们不是致富的工具。我们一定要保护熊猫,一些熊猫已找到,还有一些熊猫还在受那无尽的痛苦折磨。我们要将心比心,假如自己是它们,受到这种痛苦会怎么样?

在这里,我呼吁大家:爱护动物,让动物不再惧怕我们,让这个世界变得真正和平吧!

同时我也奉劝那些伤害熊猫的人:熊猫也有生命,熊猫也有感情。它们的价值并不是让我们赚钱,而是为自己而活。希望你们能到此收手!

篇18:写濒临危机动物的英语作文北极熊

全文共 3755 字

+ 加入清单

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。
