Every year on October 4th is the World Animal Day. It is proposed by the Italian monk St Francis in 12th century. He lives in the forests of Assisi Island for the long time, building a good relationship with the animals. So he asks people to express thanks to the animals on October 4th. He sets a good example for our human beings about how to deal with the relationship with animals. In order to memorize him and what he does, we make October, 4th to be World Animal Day. Nowadays, people from all over the world will hold various activities to celebrate on that day. The aim of this festival is to remind people to care for all animals and build a harmonious relationship with them.

每年的十月四日是世界动物日。它是由意大利修道士圣弗兰西斯在十二世纪提出的。他长期生活在阿西西岛上的森林中,与动物建立了良好的关系。所以他要求村民们在10月4日这天向动物表示感谢。他为如何正确处理与动物的关系树立了一个很好的榜样。后人为了纪念他和他所做的,我们把十月四号定为世界动物日。现在,在那一天来自世界各地的人会用各种活动来庆祝这一节日。这一节日的目的在于提醒人们关爱所有的动物,与他们建立和谐的关系。

在我们生存的环境中,动物一直都和我们形影不离。

我们常见的动物又小鸟、青蛙、蜜蜂、鱼,还有很多家畜等等。

针对不同的动物,我们有不同的看法,理论上对于苍蝇、老鼠、蟑螂等害虫,人们总是抱着杀之而后快的心理,可还有更多的动物,它们是间接或是直接为人类服务的,是人类的朋友,我们应该去保护它们。

猫是一种家养的动物,看上去活泼可爱,它有一种本能就是抓老鼠,而老鼠是最怕猫的,也是人类最痛恨的,因此我们应该保护猫。

青蛙是一种夏天在水边常见的动物,它们以吃害虫为生,在有水的庄稼地里,它们会吃掉所有的害虫,让庄稼长的粗壮高达,因此我们应该保护青蛙。

蜜蜂是一种在花丛中经常出没的小动物,它们会采集花粉,制成蜂蜜,同时能让各类植物得以授粉结果,促进植物生长。科学家爱因斯坦曾经说过:“如果蜜蜂消失,人类最多只能活四年。”可见蜜蜂的重要性,因此我们应该保护蜜蜂。

当然也不是一概而论,比如说:狼、蛇、老虎,等凶猛动物,人类很害怕他们,可并不能说要消灭它们,甚至有些还需要去刻意保护它们。因为它们有很多正在逐年减少,乃至灭绝。追根求源是因为人类的高速发展,无休止的猎杀等等,破坏了生态平衡,动物们的食物链出现了断层,久而久之,人类会自食其果,导致毁灭。

保护动物,是我们当代文明人面临的一个重要问题,该如何去保护,值得我们深思。我认为保护动物应从我做起,不去恶意的捕杀小动物,对珍惜动物更应实施法律保护。对于生长繁殖快的有害动物,适当的予以杀灭,其中还有很多细节需要深思。

保护动物,让动物和我们共同健康的生活在我们美丽的家园吧!

饕餮,上古传说中的贪吃怪兽。只吃不出,十分贪婪。它用来比喻那些贪婪的人类。而现在的“饕餮”是越来越多了,就是那些见钱眼开,屠杀贩卖甚至大吃特吃野生动物的坏人,他们多是为了自己的利益而用动物来卖钱。

物竞天择,适者生存。这个生物法则是不可能改变的,而人类却利用这个法则,无情地残杀动物们,以达成目的——用动物身上的肉、皮毛来卖钱。

生态平衡,缺一不可。一种生物的灭绝,可能就是一条生物链的消失。而现在因为人类的破坏,有许多物种已经灭绝或者是差一点儿就灭绝灭亡了。

就举长江江豚的例子来说吧。江豚是国家一级保护动物。可是因为有人喜欢吃,还是有人挺而走险,捉来长江江豚来卖,导致现在长江江豚的数量只有大约1000条左右了。没有买卖就没有杀害,没有吃货就没有杀戮。

在美国,曾有一个餐馆,为了吸引客人,抓了一只猛兽狗熊来吸引客人。客人多起来了,餐馆老板却不给猛兽吃的。狗熊已经饿得皮包骨头了。后来因有人举报,老板被抓走了。

电捕鱼、大网捕鸟、猎枪击射……人们为了赚钱,不择手段的追害动物们。甚至有人为了让皮色更好一点,能多赚点儿钱,甚至,在动物活着的时候,扒下它们的皮毛。太残忍了啊!

濒危动物的在劫难逃,全球保护刻不容缓,现在各个国家几乎都有了保护动物的法律。还有一些明星做公益广告,让人们不要再穿着动物皮毛们做的东西了。抵制皮草制品,从我的父母家人做起。

如果地球上没有了动物,人类会怎样?降临在动物身上的命运,终究会降临在人类的身上。为了我们的子孙后代,更为了未来和谐多元化的地球,让大家都行动起来保护它们吧!

动物是人类的朋友,我们应该保护它,并不是要伤害它,我们拥有了这个世界,为什么不能让动物们和我们人类一起共同生存在这个世界上?

世界上已有很多的动物已经灭绝于我们人类之手,旅鸽就是其中之一:终年无忧无虑的生活在北美大陆上,每到迁徙的季节,它们成千上万遮天蔽日。当欧洲人刚踏上北美大陆时,这里有50多亿只旅鸽。可是欧洲人来到这里之后,由于旅鸽肉味鲜美,开始遭到他们大规模的围猎。从此,旅鸽也就一步步走向了灭绝。当时鸽肉在市场上轻易买到,密执安州一个季节里就捕获了750万只旅鸽。曾经,一个俱乐部一周就杀了5万只旅鸽,有人一天便杀了500只。他们把这些罪恶一一记录下来——那是他们比赛的成绩。甚至有人想出这样的方法——把一只旅鸽的眼睛缝上,绑在树枝上,张开罗网。它的同伴们闻讯赶来,于是一一落网。有时候,一次就能捉到上千只。这个方法一定传播得很广 。就这样,在不到100年的时间里,旅鸽从几十亿猛减到濒临灭绝。

旅鸽: 1900年野生灭绝;1914年在美国华盛顿国家博物馆的展厅里,有一只旅鸽站在一根树枝上,长长的嘴,尖尖的尾巴,展翅欲飞。但它永远告别了蓝天自云。它再也不能动,不能叫,不能吃东西了。这是世界上最后一只旅鸽,而且是一只标本。那双木然的眼睛,怅望着这个世纪的人们,是怎样的捕杀它的同类,是怎么剥它的皮抽它的筋剜它的肉的。

如果我们人类再不制止,生态就会不平衡,世界的资源就循环,我们人类也会灭绝。

虽然有些动物会伤害我们人类,但那是我们人类破坏了它们的生存环境和食物才导致的。只要我们保护环境、保护动物,让动物和我们一起生活在这个美丽的家园----地球,那我们的生活不就更美好。

让我们和动物一起这个美丽的家园吧!

地球上的物种多种多样,但灭绝的物种也不计其数。其中,有绝大多数物种是应为一种生物的消失,而相继灭绝的。渡渡鸟和大颅榄树就是一个典型的例子。

渡渡鸟,又称毛里求斯渡渡鸟、愚鸠、孤鸽,是仅产于印度洋毛里求斯岛上一种不会飞的鸟,它站着有三英尺高,以水果为食,生活在陆地,肉质极其鲜美,性格温顺。见到人类不但不躲,反而迎上去,所以它们就一只只倒在了我们人类的枪口之下。毛里求斯岛上有一种树,叫做大颅榄树,是一种高大的热带乔木,树高可达一百英尺,树围十四英尺。它的果壳坚硬,必须由渡渡鸟的肠胃将壳磨薄才能发芽。现在人们已经发现了这个问题,采取了相应的措施,大颅榄树才得以生存下来。

Many people believe that we have developed into a “throw-away society” which is filling with plastic bags and rubbish. What do you think?

Wind blows up bags higher and higher in the sky. It is a scary thought that some day the earth will turn into a huge garbage land. Wastes, if not treated properly, will make our life a living nightmare.

The environmental issue is getting worse almost every day in cities with very large population. As is often the case, city development outpaces environmental protection. People consume great amount of natural resources and produce wastes. To effectively address such problems, cities need to spend big money. In addition, they need to call to the attention of people to become more environmentally responsible.

Many people are becoming less responsible and easily influenced by bad behaviors. “Why should I care while others shouldn’t?” Such idea makes some people only concern with places where they live and work. Furthermore, people sometimes even purposely litter for revenge to other people.

Although media promotes environmental awareness, good people are often snubbed as posers who try to set up a superior image in real life. Consequently, they are intimated of receiving negative comments for doing the right thing. Wrong as it is, such phenomenon is widespread especially among youngsters and people with low income and little education.

However, our society is waging a campaign against environmental pollution. People learn the harms of un-degradable lunch boxes and other polluting wastes. Laws in many countries prohibit or limit excessive use of polluting bags. Companies are continually replacing the old materials with more environmental friendly and recyclable kinds. Scientists have developed more effective technologies in waste treatment. As time goes by, more and more people put high priority on the protection of environment for a healthier life.

To sum up, people produce huge amount of garbage and the environment is seriously polluted because of lack of financial resources, sense of responsibility, or efforts. But the world will not turn into a “throw away” society if people put in sufficient efforts to protect our environment.

篇17: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。

环境对人类十分重要,可是有些人不爱护环境,也不知道环境对人类的重要性。

你看,许多人都不爱护环境,它们随地扔垃圾,有些人认为:一个垃圾算什么?可是积少成多,小区里最好看的地方成了垃圾站。有些人为了建房子挖山砍树,美丽的小山变成了沙漠和房子。有些人没时间做饭,就在外面快餐店买了饭一边走一边吃,吃完饭后他们还把一次性饭盒,一次性筷子丢在地上。有些人为了展示自己家里很有钱就开着跑车在路面上到处跑。他们没有意识到既污染环境又浪费能源。有些工厂将一些污水、浓烟排入江河和天空。

为了我们的环境,为了我们的生活,我希望人们可以把垃圾扔进垃圾桶,少砍树多造林,尽量回家吃饭。将废气废水引入地下,不要展示自己多么有钱,要注意节能减排。

一天,天气晴朗,我吃完早饭,就拿着一个渔网和一个瓶子高高兴兴地去小河边玩。

我看到了小河里有一群群可爱的小蝌蚪,像许多小逗号一样,在水里快活的游了起来游去。我心想:“如果把小蝌蚪捞起来,拿回家,就可以每天玩了”。于是我一下子捞住了几只小蝌蚪,装进瓶子里,高高兴兴地跑回家。

晚上,吃过晚饭,我就坐在沙发上听收音机,收音机里边说了一句话:“保护动物,人人有责”。于是我赶快拿出“动物百科全书”来看,原来青蛙是益虫。

第二天,我拿着瓶子跑到河边把小蝌蚪放了,它好像在说:“小朋友,谢谢你,我一定快快长大变成青蛙,消灭害虫”。

小朋友们,以后我们都要爱护小青蛙,因为它们能吃许多的害虫,保护庄稼,是我们人类的好朋友。

When a bear asked for some food by waving its ann, a visitor threw something to it. At once I went up to him and said without thinking,Dont do that. Its bad for it. If you really love them, take good care of them. His face turned red and answered he wouldnt do that again.
