+ 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。

+ 加入清单Our modern city is too crowded, and to solve the problem, three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple, One Child” in order to reduce the birth rate. Secondly, the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers, schools, hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out, the city population will be greatly reduced.
我们现代城市太拥挤了,要解决这个问题,提出了三点建议。大多数人认为我们应该在政策上“迟婚”和“一对一”,以降低出生率。其次,城市政府必须严格控制农村人口进入城市,从事贸易或从事各种体力劳动,减少人口增长造成的压力。最后,越来越多的人建议,居住在购物中心、学校、医院、电影院、剧院等生活街区,城市郊区或郊区的城市应该建在城市郊区或城市周边的城市。在这个方式中,城市居民将被鼓励在那里生活和工作。如果这三项建议都很好地实施,城市人口将大大减少。

不一会儿,我就把这本收看了完了。这本书太有意思了,太神奇了。文中的小女孩有一种与生俱有的本领,在怒不可遏时,她的手指就会施出魔法来。她的邻居革利鸽夫妇一家爱好打猎。有一次,当小女孩看到她们又去打野鸭子时,她生气了,她怒不可遏,她的手指又施出魔法了,把革利鸽夫妇一家变成会飞的野鸭子,把野鸭子变成了人。这样,革利鸽夫妇一家就只有到树上搭窝、睡觉,饿了就吃树上的苹果,而野鸭子却占有了他们的家。野鸭子拿着枪要打革利鸽夫妇一家,革利鸽夫妇一家吓坏了,当野鸭子准备开枪时,革利鸽夫妇一家说:“我们以后再也不打猎了。”之后,魔法消失了,革利鸽夫妇一家又变回了人样,从此以后,他们改名叫“爱鸽先生”、“爱鸽夫人”,再也不打猎了。这个故事真是太有趣了,这个魔法太有趣了,它可以让打猎者和被猎者彻底掉了个儿。达尔的奇思妙想让人坊起来真是忍俊不禁。
读了这个故事,我明白了:我们不能伤害动物,相反地,我们要很好地保护好对人类有益的动物,因为动物是人类的朋友。只有这样,我们的地球才会越来越可爱,我们的家园才会越来越美丽,我们才能生活得越来越幸福!
篇15:保护动物,与自然和谐
全文共 2018 字
+ 加入清单曾经,我就被一部有关动物的电视记录片深深地吸引。并不是因为难得见到这些凶猛的大型野生动物的新鲜感,而是那在莽原旷野中,驰骋天地间的自由与彪悍,是那捍卫生命、繁衍生息的勇猛搏斗和艰辛觅食的生命意志。
曾经,我见过一位摄影家从西藏拍摄的一幅照片,并为之振奋。那是雪地里一只双目凝视着远方的狼,那双在雪地里所独有的眼睛,坚定、深邃、英气逼人、摄人心魄。它的双目积聚着强大的力量,我想再奋勇无畏的人面对如此一双血腥的眼睛都会畏惧三分。它蓄势待发,随时攻击觅食或者反应攻击,捍卫自己生命的存在和尊严。不为别的,只为生存。
曾经,我观看过徐悲鸿的画展。一幅奔马图让人印象深刻。地面上扬起的尘土更突出了雄浑壮阔与豪迈。在铅灰色的乌云映衬下,越发荡起人潜在的一股力量,很莫名,只感到全身的血液在沸腾,就如同波涛汹涌,一发不可收拾。生命的存在,使它们凭籍着对生存的强烈渴望和不屈的生命意志,大范围地迁徒,艰苦地寻找水源和草场,在充满危险的静谧中顽强地生活着,构成茫茫草原上跳动的生命旋律,成为美丽草原上的生命风景线。
欣赏,是必然的。因为我们毕竟生活在钢筋水泥构筑成的空间里,有时感到很压抑,潜在的想宣泄一番,爆发出野生动物似的英豪气度。在无数次挣扎后,我们常常被这种野性的激情感染,渴望如它们一样盎然的生机勃勃,激扬奔放,不受任何束缚地去做回自我;聆听着它们强劲的生命节拍,在心灵深处回荡起强烈的回应和信念,终于领悟了人生。
正是由于自然界的包罗万象,有如此之多生灵尤其是野生动物的存在,才使人类在这个世界中不再孤独。它们不仅仅是人类的朋友,它们更是世界中与人类一样的平等的生命,有个性、有灵魂,更有无限的激情为自己生命的尊严而怒吼。自由、自信、奔放、激昂,生命本该如此。如果没有了野生动物,我们将与自然隔绝,到那时,我们该何去何从?人类的道路又会有多远?生命的真正含义该如何获取?我茫然了,无助袭上心头。只为人类自己的所作所为而感悲哀!
对于自然而言,每一个生灵都是平等的、自由的。自然界充满了残酷的竞争:有骄傲的胜利,有惨烈的失败,更有无情的死亡;有甘甜,更有艰辛和苦难;但是无论如何,不能也不会没有生命的激情。
自然竞争是残酷的、野性的,然而整个自然界是和谐的、完善的。人类来到世界,也是自然界的一个组成分子,向往野性,回归自然是人类内心深处埋藏着的本性。所以,我们更该约束自己,善待生灵,敬重生命,保护自然。地球上不能只剩下人类自己,地球也不只为人类而存在。
一幅画面在我眼前展开,一群充满野性的动物在呼唤!
保护大自然,让我们在自然成长
在这个瞬息万变的世界里,有太多的冷漠与无助,然而,从小便穿梭在钢筋水泥筑成的石头森林的你,是否曾将自己扔进那片奇妙无穷的大自然,抛开所有的世俗与功利,去真切地体会一下生命最原始的精彩?
春天,万物复苏,百花争艳。朋友,你是否因为早春的寒冷,把春天紧紧地锁在了门外?不,你需要为自己打开一扇窗,去呼吸大自然苏醒时的气息!拨开枝条上覆盖的春雪,去寻找那一丝新绿!撩开心头的愁云,去享受那一缕缕明媚的阳光!你尽可以让那一片片绿养养你的眼睛,让那一阵阵泥土的芳香熏染你的鼻子,让一颗颗野果塞满你的嘴巴,让那一声声鸟鸣充满你的耳鼓。你可以抛开一切让你烦心的事,拽着风筝的线,在草地上尽情地奔跑;你可以避开一切让你不开心的人,蹬上运动鞋,在野外采摘一朵朵美丽的野花;你可以……
夏天,大自然开始昌盛起来。朋友,你是否因为夏日的酷暑,而遗忘了那一轮明亮的圆月?不,你需要走出房门,抬起头,去观赏眨眼的星星!靠近墙角,去聆听那不知名的虫儿的歌声!赤着脚走进欢快的小溪,去感受那淙淙的流水从你指尖滑过!当然,你还可以折一枝柳条编成环,再插上几朵花儿,把自己幻想成一个花仙子。
秋天,对许多人来说,是伤感而哀愁的。朋友,你是否因为害怕哪一片凋零的树叶触及你不堪回首的往事,而拒绝感受那金灿灿的秋天?不,你需要为自己珍藏一片火红的枫叶,纪念那燃烧的青春,哪怕是痛苦也好沉沦也罢,青春终归无悔!对了,我们可不能忘了那些沉甸甸的果实,它们在这个收获的季节里笑得正欢呢!你看,它们那胖胖的身体已压弯了枝条,迫不及待地要跌落下来!还有那“晴空一鹤排云上,便引诗情到碧霄”的秋天,正是文人墨客吟诗作赋的季节……是的,朋友,秋风吹来的不再是伤心的往事,而是那沉沉的希望与无尽的豪情!
冬天,冰雪裹住了世界。朋友,你是否因为冬日的严寒,而收起了那个银色的梦?不,你需要解开大衣,在自家小院里,做一个红鼻子的雪人,让它打开你记忆的门,回到天真烂漫的童年,你可以观赏那一棵棵挺拔的劲松在大雪中昂首挺立,你可以走近那一株株不畏寒冷的腊梅,看它静静地在寒风中微笑……
朋友,生活的琐碎已让你的心灵麻木,世事的变迁已让你的灵魂郁闷,也许你正抱怨,也许你正烦恼,可是你是否认真为自己寻觅过一丝欢乐,哪怕是最原始的?
朋友,走近那片精彩的大自然,让你的生活更精彩!

篇17:保护动物初中作文800字

+ 加入清单一日三餐,都要吃东西,而肉则是必不可少的,我们吃的大多数都是鸡鸭鱼肉,这些没啥大不了。可是一些珍稀动物也被摆上了餐桌,如鳄鱼,江豚,鲸等。
我们都是地球妈妈的孩子,又何必要向兄弟姐妹下此毒手呢?
其实大自然是一个相当复杂的食物链,里面的生物可谓缺一不可。缺了其中的任何一种都会早产极大的后果,就会乱了套。在此就举几个例子吧:
蛇,众所周知蛇是无足的爬行动物的总称目前全球共有3000多种蛇类。身体细长,四肢退化,无可活动的眼睑,无耳孔,无四肢,无前肢带,身体表面覆盖有鳞。部分有毒,但大多数无毒。蛇类中最毒的要数大洋洲的太攀蛇和内陆太攀蛇。它每咬一口释出的毒液已足够杀死100个成年人,最长的蛇要属网斑蟒它。
是人们知道的唯一体长达10米的蟒蛇。网斑蟒通常生活在热带的亚洲地区,依靠身体的重量缠死猎物,眼镜王蛇也应是大家较为熟悉的一种,是最长的毒蛇,喜欢捕食蛇。你们知道吗,在一些地方蛇已经成为了保护动物。你们知道吗蛇的毒液已被用来治疗一些不治之症。而且可以成为史上最强的麻醉剂。
再说鳄鱼。鳄鱼是迄今发现活着的最早和最原始的动物之一,它是在三叠纪至白垩纪的中生代( 约两亿年以前)由两栖类进化而来,延续至今仍是半水生且性情凶猛的爬行动物,它和恐龙是同时代的动物,恐龙的灭绝不管是环境的影响,还是自身的原因,都已是化石;鳄鱼的存在证明它更加强盛的生命力。
被誉为活化石的他们已经越来越无法适应当前的环境了,仅存的23种中,有17大概种处在濒危状态鳄鱼全身都是宝,他们的皮可以做为鳄皮大衣,肉可以做成汤, 血清提取出来的胎蛋白将成为史上最强大的抗生素,甚至可以抗击艾滋病。这可谓是一项重大成功的发现。
啊!
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。

英语环境保护类作文【2】
Dear Jack,
Thank you for your letter asking about our discussion on low carbon lifestyle.
Here is something about it.
We can do a lot in our daily life to achieve the goal of living low carbon life.
First, we’d better turn off lights if possible and spend less time watching TV or surfing the Internet.
Saving water also matters much.
Besides, we should sort out the rubbish, hoping that we might recycle some, which will surely benefit us a great deal.
In addition, we suggest using handkerchiefs instead of tissues so that we can prevent more trees from being cut down.
More importantly, when we go out, walking, riding bikes or taking buses should be our first choice, which contributes to a cleaner world.

篇19:保护环境的英语

+ 加入清单Chinahas a very long and brilliant history, whose people are so friendly
and hospitable. But I am wondering why some people pay such little attention to
the environment and nature. In many places of the countryside, rivers have
become stinking sewers and brooks have disappeared. Heaps of garbage obstructs
the scarce flow of dirty water. The grounds are littered with plastic bottles
and bags. People are cutting down trees even though it is illegal. In some
towns, rubbish is hidden behind walls. Garbage cans are often of little use,
making cleaners must rush all day long and also by night to clean the
rubbish.
This lack of consideration for nature in general is extremely detrimental
to children’s education, toChina’s image, to public health, to tourism and to
the future.Chinais the common treasure of all Chinese, and we should live up to
be a member of this big family, a descendant of 5000-year-plus ancient civilized
country. I think the environment must absolutely be strictly protected by all
means. This protection should go at the same pace as the marvelous development
of the nation.
In this respect,Germanyis a rare model and leaves me a very deep
impression. After you have an exciting tour around in this country for a week or
so, it is unnecessary for you to polish your leather shoes. Personally, first of
all, the strong awareness of people’s environmental protection; then, the
advanced technology applied in the field of preserving the nature; We can learn
form others in building China into one of the most environmentally friendly
places in the world.

+ 加入清单Why should we protect wildlife animals?
Do you know of any endangered animals?Why are they in danger?
I think there are many endangered animals in the world,such as tigers and pandas.When farmers cut down trees,tigers can no longer hide and hunt.Many tigers are killed by people who want to sell their fur for money.And there are few places where pandas can live.We are not alone in the world.We human beings could not live without all the plants and animals around us.So protecting wildlife animals are very important.We must take measures to keep plants from being destroyed and stop animals from being killed.If each of us can plant a tree and build a birdhouse,the world will be more beautiful.It is very easy but useful.
