地球脉动-两极之间Planet-Earth-From-Ploe-to-Pole讲课教案
Representative Creatures
Polar day 极昼
Polar bears北极熊
It’s march. And light returns to high Arctic, a Polar bear stirs from her den. Her emergence marks the beginning of spring. And the little bears come to their mother to get food. Their mother that has not eaten for 5 months and has lost half her body weight converts the last of her fat reserves into milk for her babies. Temperature -30 . The babies still need to live in the shelter. The sun will dissolve the ice, which will hinder the bear to hunt its food(seal). Nearly half of the baby bears will die in the first year in the broken ice.
All animals, rare or common,gy on the sun.
Jungle
Birds of paradise
In the tropics the sun’s rays strike the earth head on, so the jungle grows so vigorously and supports so much life. This forest covers only 3 percent of the planet’s surface, but it contains more than 50 percent of all its plants and animals. There are 42 different species of birds of paradise living in the great island of New Guinea, each more bizarre than the last.

从高空俯瞰显得空空如也，死气沉沉，但是走近沙漠的话就会发现完全不同的情形。
第6集冰封世界Ice Worlds地球的南北极分别是南极洲和北冰洋，它们几乎长年都是冰天雪地。
春去秋来，太阳直射点发生迁移的时候，这两个冰封的世界随之发生最极端的季节变化，从极地冬天的黑暗和严寒转变到极地夏天的午夜和光明，太阳全天24小时不落。
第7集辽阔草原Great Plains非洲热带草原、西伯利亚平原、北极苔原和北美大草原等是世界上最大的平原。
它们一共占到了陆地表面的1/4，它们的核心特点就是长满了草。
这种谦卑的植物养活着世界上最大的动物群落。

Earth.这些偏僻岛屿上为生存所做的努力，正如地球上所有生命都要面临的挑战The tiny island of Escudo off the coast of Panama.巴拿马海岸线边的埃斯库多岛Home to the pygmy three-toed sloth.是侏三趾树懒的栖息地This is a male and life here suits him well.这是一只雄性树懒，在这里生活得十分惬意Mangroves provide all the leaves he can eat红树林为他提供食物and there are no predators to worry him.也没有天敌前来叨扰Island life may seem idyllic岛上的生活似牧歌般悠闲but it comes at a price.但这是有代价的There are only a few hundred pygmy sloths in existence.这座岛上只有几百只雌性侏三指树懒And he needs a mate.而他需要配偶That's an enticing call... from a female.这雌性的叫声好生诱人Somewhere out there.就在不远的某个地方And this, for a sloth, is a quick reaction.对树懒来说这反应堪称迅猛The problem is, there's deep water between them.但问题是中间隔着一渊深潭So what should any red-blooded sloth do?那么一只气血方刚的树懒会怎么做呢Swim, of course.当然是游过去Could this be her?那会是她吗He does his best to put on a turn of speed.他尽全力加快速度But she's not the one.但叫的不是她She already has a baby这只母树懒已经有了一只幼崽and she won't mate again until it leaves her in about six months' time. 在幼崽六个月后长大离开之前她不会再次交配Even life on a paradise island can have its limitations.即使生活在天堂之岛也会有限制But at least she can't be far away.但至少她就在不远处The world's entire population of pygmy sloths is isolated地球上所有的侏三指树懒都生活在on a speck of land no bigger than New York's Central Park.这片不及纽约中央公园大小的岛屿上The size of an island has a huge influence岛屿的大小极大地影响着on the fate of those cast away there.生活在那里的动物The island of Komodo in Indonesia.这是印度尼西亚的科莫多岛Home to dragons.龙之巢穴Ten feet long and weighing an impressive 150 lbs,体长三米重达六十八公斤these are the largest living lizards on the planet.他们是地球上现存体型最大的蜥蜴It's unusual to find large predators on islands.大型食肉动物在岛屿上并不常见Yet, for four million years,然而四百万年来the Komodo dragon has dominated here.这么小的岛屿似乎不可能It might seem there wouldn't be enough food to support such giants on this relatively small island. 科莫多巨蜥一直称霸这里But reptiles, being cold-blooded,为这种庞然大物提供充足的食物来源但冷血爬行动物只需要need only about a tenth of the food a carnivorous mammal would.肉食性哺乳动物十分之一的食物量A single meal will last a dragon a month.巨蜥一餐可以支撑一个月They are so successful that their only serious competition comes from others of their own kind.他们的生存之道如此成功And there are some 2,000 of them here.以至于唯一的天敌就是他们的同类This giant,

strayed into someone else's patch.目前为止一切顺利Another huge male thinks he is the king here.但他误入别人的领地Space being limited on islands,另一只雄性巨蜥认为它才是这里的王dragon territories overlap岛屿上空间有限and that creates continual conflict.巨蜥的地盘时常重叠In dragon society, size is everything.导致冲突不断But if rivals are closely matched,在巨蜥族群里体型决定一切the outcome can be uncertain.但如果双方体型相当Muscular tails strike with the power of

continents.但有些岛屿却幅员辽阔And these provide opportunities for life更像是一块小型大陆to experiment and evolve.这为不同生命的进化与试验Madagascar is one of the biggest islands提供了机会and also one of the oldest,马达加斯加是地球上最大的岛屿之一having split away from Africa over 120 million years ago.也是最古老的岛屿之一With time and isolation,它在一亿两千万年前就已经脱离非洲大陆its animals have adapted随着时间流逝与地理隔断的出现to take advantage of every available niche.岛上的动物们不断适应The island now has some 250,000 different species,充分利用一切可用资源most found nowhere else on Earth.这座岛上现存约二十五万不同的物种These are not monkeys, but lemurs.大部分都是该地区特有种From a single ancestor,这些不是猴子而是狐猴about 100 different types have evolved.他们从同一个祖先The largest, the indri, seldom comes down from the branches. 进化出一百个不同的种The much smaller ringtails体型最大的马达加斯加大狐猴极少下树wander in troops across the forest floor体型小许多的环尾狐猴searching for food.成群结队地扫荡森林地面And tiny bamboo lemurs eat nothing except bamboo.寻找食物With few competitors, lemurs have been free to colonise极小的驯狐猴只吃竹子almost every

a little corner of Madagascar to himself.如果他能掌握这片森林中特有的生存方法Island life encourages animals to do things differently.就能在马达加斯加岛上谋得一席之地And on some islands that is essential.岛屿生态迫使动物另辟蹊径There are islands still forming today...在某些岛上这是必备的生存技能built by volcanoes.由于火山运动Some erupt explosively.现在仍有岛屿不断形成Others pour out rivers of molten rock.有些火山喷发剧烈Lava.有些则熔化岩石In the last 50 years,化作岩浆ten new volcanic islands have been formed.在近五十年内Newly created and often remote,已经形成了十个新的火山岛they're hard for colonists to reach.由于形成时间晚又常十分偏远Even those that do find these are tough places to survive.鲜少有生命踏足This is Fernandina,即使有环境也极其难以生存one of the Galapagos Islands in the Pacific.这是费尔南迪纳岛Young and still volcanically active, it's a desolate place.太平洋加拉帕戈斯群岛的一部分The surrounding sea, however, is particularly rich with life.这座年轻的活火山岛屿一片荒凉And the frontier between these two very different worlds然而环岛的海中却孕育着丰富的生命is the home of one of the strangest of reptiles.而这两个不同世界的交界处Seagoing iguanas.生活着最奇异的爬行动物They are vegetarians,海鬣蜥but since there's little food for them on the land,它们是素食者marine iguanas graze on the sea floor.但由于岛上没有能吃的食物A big male like this one can dive to 30 metres所以海鬣蜥以海底的植物为食and hold his breath for half an hour.这种体型的雄性海鬣蜥可潜到水下三十米There are more than 7,000 individuals屏住呼吸长达半小时on Fernandina alone.仅在费尔南迪纳岛上And by bringing nutrients from the sea to the land,就有超过七千只海鬣蜥the iguanas help other animals to survive here, too.它们往返近海获取食物养活自己Crabs feed on dead skin on the iguana's back同时还帮助了其它动物在此生存and, in turn, provide a welcome exfoliation service.红石蟹以海鬣蜥背上的死皮为食While smaller lizards prey on the flies that pester the colony. 反过来也热情地为它们提供去角质服务But not all the relationships on this island are so harmonious. 小型蜥蜴还捕食纠缠海鬣蜥的苍蝇Marine iguanas lay their eggs in sand.但岛上的生存关系并不是都如此和谐In June, when the hatchlings emerge, they are vulnerable.海鬣蜥将蛋下在沙子里They must join the adults at the edge of the sea.每到六月刚破壳的小鬣蜥异常脆弱But the journey will be a dangerous one.它们必须到海边与成年海鬣蜥汇合Racer snakes.但这将是一次危险的旅程The snakes miss their chance.游蛇But more babies are hatching.游蛇错失了这次机会And now the snakes are on the alert.但还有更多的小鬣蜥将孵化而出This is the best feeding opportunity they will get all year.这些游蛇正虎视眈眈On flat ground, a baby iguana can outrun a racer snake.这是它们一年里最佳的捕食时机But others are waiting in ambush.小鬣蜥在平地上跑得比游蛇快Another hatchling has但周围还有其他蛇在埋伏its first glimpse of a dangerous world.另一只刚孵化的小鬣蜥A snake's eyes aren't very good,第一次见识了这个危险的世界but they can detect movement.蛇的视力并不是很好So if the hatchling keeps its nerve,但它们可以感知到移动物体it may just avoid detection.所以如果这只小鬣蜥能保持冷静A near miraculous escape.也许能逃出它们的视线The lucky survivors can begin learning the unique way of life 近乎奇迹地逃出生天有幸活下来的小鬣蜥可以开始学习demanded by this hostile island.应对这座危险岛屿的独特方式了Although marine iguanas are expert swimmers,尽管海鬣蜥是游泳的行家they can't cross open oceans.它们也无法横渡广阔的大海But even the stormiest waters are no barrier for birds.但再汹涌的海水都无法阻挡鸟类Gale force winds and cold temperatures make the阵阵烈风加之低温sub-Antarctic islands off New Zealand让新西兰亚南极地区的这座岛屿particularly unwelcoming in winter.在冬天变得尤其不友好But, when the brief summer comes,但当短暂的夏日来临时temperatures rise and winds slacken.这里将变得风和日丽It's now that visitors arrive.正是游客到访的好时节All here to breed before winter returns.都趁着冬天来临之前来这里繁殖There's the Snares penguins.这些是斯岛黄眉企鹅Shearwaters come, too.海鸥也来到这里This is an excellent place for them to dig their nesting burrows, 因为没有天敌能够靠近这里for no predators have managed to get here.这里成为海鸥挖掘地窝的绝佳场所Soon the island is crowded with birds.很快岛上会到处都是鸟Every one of them eager to每只鸟都急切地想充分利用make the most of the short breeding season.他们短暂的繁育季节But not everyone has a partner.但并不是所有鸟都有伴侣A male Buller's albatross waits for his mate.一只雄性新西兰信天翁正等待另一半的到来Each year they spend six months apart, travelling the ocean. 每年他们都将分开六个月各自在海上飞行They reunite here to breed.他们将在这里汇合生育下一代But this year, she's late.但今年雌性信天翁还没有到No, that's not her.不那不是她The other birds come and go.其他鸟儿来来往往The clock is ticking.时间所剩无几If she doesn't appear soon,如果雌性信天翁还不出现it could be too late for them to breed successfully. 他们将错过顺利繁衍后代的机会Every morning the shearwaters每天清晨海鸥飞离这里fly off to collect food for their young.为他们的孩子寻找食物Everybody else seems to be getting on with it.每只鸟儿似乎都在抓紧干The shearwaters' return marks another lost day.海鸥的归来意味着又一天过去了There are three million birds on the island,这个岛上有三百万只鸟but only one matters to him.但他只在乎那一只Could this be her?这会是她吗At last.总算回来啦At first, he's a little coy.一开始雄性信天翁还有些害羞But not for long.但很快就放开了They greet each other with the special dance他们用多年来练成的独特舞蹈they've perfected over many years.向彼此表示问候There is much to do如果他们还打算在冬天来临前养育孩子if they're to raise a chick before winter returns.要做的事情还有很多But when you have been apart for six months,但当你和某人分开大半年some things can't be rushed.有些事需要慢慢来Islands in warm tropical waters地处温暖热带海域的岛屿don't experience seasonal extremes.无法体验极端的季节变化The Seychelles, lying off the coast of East Africa, 位于非洲东海岸的塞舌尔群岛provide a sanctuary for sea birds all the year round. 是海鸟们全年的庇护天堂Fairy Terns are permanent residents.塞舌尔白燕鸥是这里的永久居民They take a fairly relaxed view about what constitutes a nest. 它们筑巢并不讲究A bare branch is quite enough.一根光秃秃的树枝就足够了Climbing onto it to incubate has to be done with care.不过爬上去孵蛋需要格外小心Once a year, the noddies arrive.每年白燕鸥都会来一次They do make nests,它们老实筑窝and Pisonia trees provide their young腺果藤树能让小鸟的幼年with a rather less precarious start in life.过得安全一些Nesting on this island looks idyllic.在这个岛上筑巢看起来几乎完美But behind the beauty, there's a sinister side.但美丽的表象后也有危险的一面The Seychelles fody makes quick work of an unattended egg. 塞舌尔福迪雀偷袭了无人照看的蛋She knows something's not quite right,她知道事情有点不太对劲but her drive to incubate is strong.但她孵化的意愿很强烈The noddies too have a problem.黑燕鸥也遇上了麻烦As their chicks grow,随着雏鸟一天天长大so the pisonia trees develop seeds that are sticky腺果藤树长出了黏黏的and equipped with hooks.带有倒钩的种子By the time the young noddies leave,新一代黑燕鸥离巢的时候they carry these hitchhiking seeds away to other islands.会带着这些搭顺风车的种子前往其它岛屿But sometimes the pisonia trees are too successful.但有时腺果藤树的策略过于成功If a fledgling, testing out its wings, drops to the ground,如果幼鸟在学习飞翔时跌落地面it can get covered with the seeds.它身上会挂满这些种子Entangled and weighed down,汁液粘腻越粘越重if it can't free itself,the youngster will starve.如果它摆脱不了就会饿死The pisonia may have failed to disperse these seeds...这样腺果藤的种子无法传播这也是人们称腺果藤树为"捕鸟树"的原因但种子扎根很快就有好肥料了..but it will soon have fertiliser for its roots. 白燕鸥又下了一颗蛋This is why some people call the pisonia the "Bird catcher tree".现在她要养一只小鸟了The fairy tern laid another egg,这只小鸟很幸运and now she has a tiny chick to feed.等它羽翼丰满之时This chick is lucky.腺果藤树种子已经传播完毕By the time it fledges,它们带来的危险也将不复存在the pisonia seeds will have dispersed,再诗情画意的岛屿and the danger they brought will be gone.岛上的动物也要面临挑战Even the most idyllic-looking of islands presents challenges但它们眼前的最大威胁已经改变for the animals living there.这是印度洋上的圣诞岛But the greatest threat they face is change.数百万年以来Christmas Island in the Indian Ocean.这块遥远的陆地一直被蟹类统治着For millions of years,它们的祖先来自海洋this remote speck of land has been ruled by crabs.但绝大多数品种现在已经适应了陆地上的生活Their ancestors came from the sea,鉴于它们的数量众多but most have now adopted a land-based existence.彼此之间还算相对和谐Given there are so many of them,它们是这个小小蟹类乌托邦的园丁和守卫they get on relatively harmoniously.每年它们都会回到海洋中进行繁殖They're the gardeners and caretakers of a tiny crab utopia.而红蟹大迁徙Once a year, they must all return to the sea to breed,是地球是最伟大的自然奇观之一and the march of the red crabs迁徙的红蟹数量多达五千万只is one of the greatest natural spectacles on earth.这一景象让这座岛屿举世闻名There are 50 million of them.但近些年来It's an event that has brought the island worldwide fame.数以百万的红蟹未能成功抵达海洋But in recent years,一种入侵物种占领了这座岛屿millions of red crabs haven't managed to reach the sea.黄疯蚁An invader has occupied this island.它们搭乘来访的船只来到岛上Yellow crazy ants.由于缺乏天敌控制They escaped from visiting ships它们在森林里建立了巨大的超级蚁群and with no predators to control them,当迁徙的红蟹经过它们的领地时they have now created vast super colonies in the forest.黄疯蚁便展开攻击When migrating red crabs march into their territory,它们朝红蟹的双眼和嘴中喷射酸液the ants attack.红蟹毫无还手之力Squirting acid into the crabs' eyes and mouths.双目失明迷失方向The crabs have no defence.它们便死定了..they're doomed.Blinded and confused...Humans brought these ant invaders here,是人类把这些蚂蚁入侵者带上了岛and now humans are having to control them.而现在人类不得不采取措施控制局面Isolated communities may evolve与世隔绝的动物群落from millions of years in relative peace.可能在数百万年内演化出了相对稳定的生态But, when new challenges arrive, they can struggle to cope. 但当新挑战来袭它们只能尽力去应对Of all the species that have become extinct in recent years, 近年来濒于灭绝的物种之中around 80% have been islanders.大约百分之八十是岛屿物种Our impact on the Earth is greater today人类对地球所造成的影响than ever before.比以往任何时候都要深远Yet some islands are so remote然而有些岛屿是如此偏远that few humans have even set foot on them.以至于几乎没有人类踏足Zavodovski Island is one.扎沃多夫斯基岛就是一例It lies in the great Southern Ocean.它地处南太平洋It's not only surrounded by the stormiest of seas,不仅被最猛烈的海洋风暴所环绕it is itself an active volcano.而且本身就是座活火山It's the last place on Earth you would choose to live.这里是地球上你最不愿居住的地方Unless you're a chinstrap penguin.除非你是一只南极帽带企鹅There is plenty of food in these waters, but to exploit it, 这里的水域食物充足但若想享用美食the penguins have to risk their lives.这些企鹅得冒着生命危险Life here is dangerous in the extreme.这里的生活险象环生But there are some benefits from living on a volcano. 但生活在火山上还是有一些好处的Its warmth melts the snow early in the year.火山的热量每年早早地融化了积雪And, by January, the Antarctic's mid-summer,到了一月南极地区的仲夏时节the island is covered in chicks.整座岛被小企鹅覆盖Parents take turns at guarding them双亲轮流守护幼崽until they're large enough to be left alone.直到它们成长到足以独立生活This mother's chicks are hungry,这几只小鸟饿了but she has no food left to give them.但母亲没有食物可以喂它们Their survival depends on their father生存与否取决于它们的父亲returning with the next meal.能否带着食物归来But some don't make it.有些企鹅确实一去不返Skuas harass the colony,贼鸥不断侵扰着企鹅种群hoping to snatch a chick.希望能趁机叼走一只雏鸟She can't risk leaving them.母亲不能冒险离开自己的雏鸟Everything will be fine, as long as their father comes back soon. 只要父亲尽快回来情况就会好转80公里的海域捕鱼他前往远离海岸但他现在离家不远了He's been fishing 50 miles offshore,对于他和这里所有的企鹅父母来说but now he's not far away.归途中最糟糕的一段还在后面For him, however, and for all the other parents here,他的小脚爪帮助他the worst of the journey is still to come.攀附住陡峭的火山岩Tiny claws help him对于这些往返的企鹅来说to get whatever grip he can on the rough lava.现在是高峰时刻For these commuters,有些企鹅今天不太顺利it's rush hour.这位父亲要走三公里的路才能到家Some have had a really bad day.肚里塞满食物路越发难走The father now has a two-mile walk to the nest,周围还有全球数量最庞大的企鹅种群and a stomach loaded with food doesn't help.但由于他每隔一天就要走一遍This is the largest penguin colony in the world.闭着眼睛都能找到回巢的路But as he makes the same journey every other day,巨大的种群数量确实能保证安全he should be able to do it with his eyes closed.但当你试图寻找自己的巢穴之时It's true that there can be safety in numbers,这也会成为问题but numbers can also be something of a problem母亲依然在等待when you're trying to find your own nest.小鸟们快要绝望了The mother is still waiting.在这震耳欲聋的叫声之中Her chicks are now desperate.他可以辨识出对方特有的声音In the midst of all this deafening chorus,总算回来了he can recognise her particular cry.两只雏鸟都能饱餐一顿At last.点头示意之后他们的母亲出发了Both chicks will get a meal.轮到她外出捕食了With a head bob of acknowledgement, their mother now leaves. 这种艰难的往返It's her turn to do the feeding run.是这些企鹅为了庇护所付出的代价This formidable commute is the price也许在我们看来这样的天堂很奇怪these penguins pay for sanctuary.但是对于一百五十万只企鹅来说A strange vision of paradise to us, perhaps,这座岛屿满足了全部所需but, for one and a half million penguins,岛屿可能既偏远而又微不足道this island has it all.但它们仍是地球上某些珍贵动物的家园Islands may seem remote and insignificant,but they are home to some of the most precious wildlife on Earth.行星地球拍摄日记The expedition to film on the island of Zavodovski前往扎沃多夫斯基岛进行拍摄was the most intrepid shoot of the series.是整个摄制过程中最勇敢的旅程To ensure its success, the team have called in为了确保拍摄成功摄制组找来了Antarctic expert Jerome Poncet,南极研究专家杰罗姆·庞赛特one of the few people to have set foot on the island. 他是为数不多上过这座岛屿的人之一This whole region of Antarctica is rarely visited.南极大陆的这个区域人迹罕至And this is the planet's roughest ocean.这里有地球上最汹涌的海洋After seven long days and nights at sea,七天七夜的航行之后they get their first glimpse of the final destination.他们终于第一次看到了目的地It's actually quite surreal after a whole year,整整一年来我们一直在集结队伍trying to put the expedition together.今天一觉醒来火山就在眼前And then today we wake up, and there's the volcano. 这感觉太不真实了That's Zavodovski.那就是扎沃多夫斯基岛The explorers who discovered this place发现这里的探险者spoke of the stench of sulphurous gases,说这里弥漫着含硫气体散发的恶臭treacherous waters,加上汹涌的海浪and astonishing numbers of penguins.和惊人数量的企鹅It seems not much has changed.似乎没什么大的变化Jerome's been round the whole place,杰罗姆已经绕了一圈and there literally is only one safe area to get on,只有一个可以安全登陆的地方and he's telling us it's that rock face over there.他说就是那边的岩壁The team must take everything they need to survive. 探险队必须带上所有生存所需的物品There are the penguins!快看企鹅Though the boat'll stay nearby,尽管船就停在附近they will need to be self-sufficient.他们也必须带上充足的物资But that means taking a tonne of equipment up this cliff.但是这意味着要把一吨的物资运上山崖Just get to that lot to help.过来这边帮忙Many flippers make light work.脚蹼多了力量大They work all day getting the gear ashore.光把设备搬上岸就花了整整一天But the fact there are so many penguins on the island但是事实上岛上的企鹅数量太多doesn't make it easy.反而增加了工作难度The hardest thing for us has been对于我们来说最难的事莫过于finding a pathway through,找一条可以穿过鸟群的路because there's absolutely penguins everywhere you look.因为这里目之所及全是企鹅Finally, it's time to make camp.终于可以安营扎寨了They choose a sheltered place that won't disturb the locals.为了不惊扰居民他们选了个隐蔽的地方But since most of the penguins won't have seen a human being before, 但是因为大多数企鹅都没见过人类they seem keen to pop over and visit.他们似乎很想来造访一下Hello. Nosy neighbours.你好爱管闲事的邻居们The team set off探险队出发to start documenting the daily lives of the penguins,开始记录企鹅的日常生活and what they find is astonishing.他们的发现令人震惊As soon as you walk over that ridge,翻过那个山脊you sort of get a tingly feeling,你会被那边的景色所震撼because I've never seen that many animals in one spot.因为我从来没见过一个地方有这么多动物It's mind-blowing.太让人兴奋了It's like Glastonbury Festival.就像格拉斯顿伯里音乐节The whole landscape整个岛上is full of little black and white penguins waddling around.全都是摇摇晃晃黑白相间的小企鹅This is penguin paradise, and that's what we're trying to show. 这里是企鹅的天堂也是我们想要展现的A promising start.这个开端充满希望But here, fortunes can change quickly.但是在这里命运瞬息万变Summertime...夏日时光Every season within ten minutes.十分钟内经历四季As the snow melts, it creates an unforeseen problem.雪融化后出现了始料未及的问题We purposely chose this campsite我们特意选择了这个营地because it was a place where the penguins didn't seem to go. 因为企鹅不太会来这里I think we've realised why the penguins don't nest here.现在我们知道了为什么企鹅不在这里筑巢It's because of the spray and because of some run-off,由于径流这里已经水漫金山so we are literally in a bit of a bog.我们真的是身陷泥潭了And it's not just mud.而且不仅仅是泥A couple of these guys,其中一些企鹅as they wander down to do a spot of fishing,在成群结队地下海捕鱼时they tend to use my tent as a little poop spot.喜欢把我的帐篷当做厕所You kind of get used to it at night,你必须要习惯晚上的时候just hearing a constant splat on top of the tent.听见从帐篷的顶上传来的不停的啪啦声But, as you can see, all of the kit,但是如你所见所有的设备I'm afraid that's getting splat on as well.恐怕也会被粪便淋到And, when the wind changes, it brings a noxious reminder当风向变化的时候吹来的有毒气体。

大部分时候我都能看得懂（难度系数多少？5·0）“地球脉动”这部片子讲的是地球上的一切。
碟一分三个部分：两极之巅（从南极一直介绍到北极）；雄伟高山（介绍了高山上的各种生物）；淡水资源（看看占地球3%的淡水里究竟有啥）。
碟二里也有三个部分：洞穴迷宫（探探洞穴里千奇百怪的生物）；奇幻沙漠（世界上条件最严酷的地方——-沙漠里生存哪些东东）；冰封世界（带你到南北极去看看冰雪里能够生存的物种）。
每部分的后面都有一个“地球脉动日记”，介绍是怎么拍摄的，并讲解一个重点。
比如“两极之巅”重点讲解怎么样从高空与地面配合拍摄鬣狗捕食的；“雄伟高山”重点讲解拍摄雪豹的艰巨。
下面我要推荐一个“地球脉动日记”。
理由：为了拍摄全世界最大的一堆便便——-蝙蝠粪便堆成的山，摄制组竟然住在了那堆便便的边上！他们真是不容易啊！最令我爸爸妈妈晕倒的是我喜欢看“地球脉动”的程度竟然超过了看“哈利波特”！因为从“地球脉动”里我学习到了以前不知道的许多知识。
听了我的介绍，你心动了吧！心动不如赶快行动，Let、us、buy“地球脉动”，一起看！《地球脉动》观后感2在昨天，我们看了一个很好看的科教影片——《地球脉动》。
听唐老师说这部影片可是获了很多国际大奖的，观看了以后，果然精彩绝伦！电影的每一个画面都是那么的精美，每一秒钟都是让人赏心悦目，每一个片段都是那么紧张刺激，同学们不时发出惊叹，感叹电影的不可思议！里面有一个场景是介绍鹿群的生存经历，可怜的小鹿最终还是让大灰狼给吃掉了，同学们看上去都很讨厌狼，因为狼太残忍，就连很小的鹿都不放过。
我也不例外，真想上去帮小鹿一把啊！电影里面还介绍了南极冰川的企鹅。

Male Emperor Penguins 雄帝企鹅
Male Emperor Penguins are facing the nearest that exists on plane Earth. Winter in Antarctica. It’s continuous dark. And temperatures drop to minus seventy degrees centigrade. The Penguins stay when all other creatures have fled. Because each guards a treasure: a single egg rested on the top of its feet. And kept warm beneath the downy bugle of its stomach. There was no food and no water for them. And them will not see the sun again for 4 months.

BBC经典-《行星地球》英文解说词（全集）
BBC经典-《行星地球》英文解说词（全集）行星地球英文解说词第1集PLANET EARTH From Pole to PoleA hundred years ago there were one and a half billion people on Earth. Now, over six billion crowd our fragile planet Earth. But even so, there are still places barely touched by humanity. This series will take to the last wildernesses and show you the planet Earth and its wildlife as you have never seen them before. Imagine our world without sun. Male Emperor penguins are facing the nearest that exists on planet Earth Earth - winter in Antarctica. It's continuously dark and temperatures drop to minus seventy degrees centigrade. The penguins stay when all other creatures have fled because each guards a treasure: a single egg rested on the top of its feet and kept warm beneath the downy bulge of its stomach. There is no food and no water for them, and they will not see the sun again for four months. Surely no greater ordeal is faced by any animal. As the sun departs from the Antarctic it lightens the skies in the far north. It's March and light returns to the high Arctic, sweeping away four months of darkness. A polar bear stirs. She has been in her den the whole winter. Her emergence marks the beginning of spring. After months of confinement underground she toboggans down the slope. Perhaps to clean her fur, perhaps for sheer joy. Her cubs gaze out of their bright new worldfor the very first time. The female calls them, but this steep slope is not the easiest place to take your first steps. But they are hungry and eager to reach their mother, who's delayed feeding them on this special day. Now she lures them with the promise of milk, the only food the cubs have known since they were borndeaf and blind beneath the snow some two months ago. Their mother has not eaten for five months and has lost half her body weight. Now she converts the last of her fat reserves into milk for her cubs. The spring sun brings warmth but also a problem for the mother. It starts to melt the sea ice. That is where she hunts for the seal she needs to feed her cubs. And she must get there before the ice breaks up. For now though it's still minus thirty degrees and the cubs must have the shelter of the den. It's six days since the bears emerged and spring is advancing rapidly. But even now blizzards can strike without warning. Being so small, the cubs are easily chilled and they will be more comfortable resting in the den. But their mother must keep them out and active. She's becoming weak from hunger and there's no food on these nursery slopes. The sea ice still holds firm, but it won't last much longer. Day 10, and the mother has led her cubs a mile from the den. It's time to put them to the test. They've grown enormously in confidence, but they don't have their mother's sense of urgency. At last it seems that they're ready for their journey and they're only just in time, for a few miles from the coast the ice is already splitting. Now the mother can start hunting forthe seals they must have, but she's leading her cubs into a dangerous new world. Nearly half of all cubs die in their first year out on the ice. Summer brings 24 hours of sunlight and the thawing shifting landscape. Further south the winter snows have almost cleared from the Arctic tundra. Northern Canada's wild frontier. Here nature stages one of her greatest dramas - Every year three million caribou migrate across the Arctic tundra. The immensity of the herd can only be properly appreciated from the air. Some herds travel over 2,000 miles a year in search of freshpastures. This is the longest overland migration made by any animal. They're constantly on the move. Newborn calves have to be up and running the day they are born. But the vast herds do not travel alone. Wolves. Packs of them, eight to ten strong, shadow the migration. And they are hungry. It's the newly born calves that they are after. Running directly at the herd is a ploy to generate panic. The herd breaks up and now it's easier to target an individual. In the chaos a calf is separated from its mother. The calf is young, but it can outrun the wolf if only it manages to keep its footing. At this stage the odds are even - either the caribou will make a mistake or after a mile the wolf will give up. Midsummer on the tundra and the sun does not set. At these latitudes the sun's rays are glancing and not enough of their energy reaches the ground to enable trees to grow. You'll need to travel 500 miles south from here before that is possible. These stunted shrubs mark the tree line - thebeginning of the boreal forest - the taiga. The needle-shaped leaves of the conifers are virtually inedible so this forest supports very little animal life. It's a silent place where the snow is unmarked by footprints. In the Arctic winter snow forms a continuous blanket across the land. But as spring creeps up from the south the taiga is unveiled. This vast forest circling the globe contains a third of all the trees on Earth and produces so much oxygen it changes the composition of the atmosphere. As we travel south so the sun's influence grows stronger and at 50 degrees of latitude a radical transformation begins. Summers here are long enough for broadleaf trees to replace conifers. Broadleaves are much easier to eat and digest so now animals can collect their share of the energy that has come from the sun. It's summer and these forests are bustling with life. But the goodtimes will not last. Broad leaves must be shed in winter for their damage by frost. As they disappear, so the land becomes barren with little for animals to eat. The inhabitants must migrate, hibernate, or face months of near starvation. The Amur leopard - the rarest cat in the world. Here, in the deciduous forests of eastern Russia the winter makes hunting very difficult. Pray animals are scarce, and there's no concealing vegetation. The cub is a year old and still dependent on its mother. Deer are frequent casualties of the harsh winter and these leopards are not above scavenging from a corpse. African leopards could never survive here, but the Russian cats have thick fur to shield them from the cold.There are only forty Amur leopards left in the wild and that number is falling. Like so many creatures, the cats have been pushed to the very edge of extinction by hunting and the destruction of their habitat. The Amur leopard symbolises the fragility of our natural heritage. The future of an entire species hangs on survival of a tiny number of mothers like this one. All animals, rare or common, ultimately depend for their energy on the sun. In Japan the arrival of the cherry blossom announces the beginning of spring. The sun's energy brings colour to the landscape. The earth, as it makes its annual journey around the sun, spins on a tilted axis. And it's this tilt that creates the seasons. The advance of the seasons brings constant change. As the sun's influence diminishes in the north, so the deciduous forests of America begin to shut down losing their leaves in preparation for the dark cold months ahead. One season hands over to another. Some organisms thrive on decay, but most must make special preparations for winter and a life with little sun. Whole populations of animals are now forced to travel great distancesin pursuit of food and warmth. 300,000 Baikal teal gather to escape from the Siberian winter by migrating south to Korea - the world's entire population in a single flock. But there are parts of the world that have no seasons. In the tropics the sun's rays strike the earth head on and their strength is more or less constant all year round. That is why the jungle grows so vigourously and supports so much life. This forest covers only 3 percent of the planet'ssurface, but it contains more than 50 percent of all its plants and animals. The canopy is particularly rich. There are monkeys, birds and millions of species of insects, exactly how many we have no idea. The character of the forest changes as we descend, becoming ever darker and damper, favouring different kinds of animals and plants. Less than 2 percent of the sunlight reaches the floor, but even here there is extraordinary variety. In the great island of New Guinea there are 42 different species of birds of paradise, each more bizarre than the last. This forest is so rich that nourishing food can be gathered very quickly. That leaves the male six-plumed bird of paradise with time to concentrate on other matters like tidying up his display area. Everything must be spick and span. All is ready. Very impressive, but no one is watching. The superb bird of paradise calls to attract a female. And he has more luck. But what does he have to do to really impress her? She retires to consider her verdict. It's hard not to feel deflated when even your best isn't good enough. The sun influences life in the oceans just as it does on land. Its richest parts are those where waves and currents bring fertilising nutrients to surface waters that are bathed in sunlight. The seas off the Cape in South Africa have this magic recipe and are hugely productive. Summer is the time of plenty and it's now that theseals start to breed. The strike of a great white shark lasts a mere second. Slowing it down forty times reveals the technique and immense strength of this massive predator. If surprise fails, there will be a chase. The shark is faster on a straight course but it can't turn as sharply as the seal, its agility versus power. Once the seals have finished breeding the giant sharks will move on. It's now becoming clear that great whites migrate thousands of miles across the oceans to harvest seasonal abundances in different seas. The sun, beating down on tropical waters, powers the weather systems of the globe. Moisture evaporates from the warming ocean and rises to create great storms. The winds generated out at sea sweep inland across the continents. As they travel across the Sahara they create the biggest of all sand storms blowing sand halfway round the world to fertilize the Amazon jungle. Winds blowing across the Indian Ocean collect moisture and sweep northwards towards the Himalayas. As the air rises, so it cools. The water it carries condenses into clouds and then falls as the life giving rains of the monsoon. So air currents powered by the sun carry wet air to the middle of continents. Without water there can be no life, but its distribution over the land is far from even. Deserts cover one third of the land's surface and they're growing bigger every year. This is the Kalahari Desert in Southern Africa. It's the dry season and thousands of elephants have started to travel in desperate search for water. All across Southern Africa animals are journeying for the same reason. Buffalo join the great trek. Nowhere else on Earth are so many animals on the move with the same urgent purpose. They're all heading for the swamps of the Okavango, a vast inland delta.At the moment it is dry, but water is coming. The travellers are hampered by dangerous dust storms. Females and calves caneasily get separated from the main herd. For this pair sanctuary lies in the patch of woodland a few miles ahead. They can't rest until they reach it. The main has already got there safely. Finally, the stragglers emerge from the dust. The exhausted calf is still blinded by sand. Its mother does everything possible to help it. The storm is now subsiding, but not all the elephants have been so lucky. One youngster has got lost. Thirsty and exhausted, it follows the tracks of its mother, but sadly in the wrong direction. At the peak of the dry season in the Kalahari water arrives in the Okavango. It fell as rain a thousand miles away in the highlands of Angola and has taken nearly five months to reach here. The water drives out insects from the parched ground, which are snapped up by plovers. Catfish, travelling with the flood, collect any drowning creatures the birds have missed. It's a seasonal feast for animals of all kinds. Birds are the first to arrive in any numbers - water cranes, then black storks. Behind the birds come buffalo. After weeks of marching their trek is coming to an end. As the water sweeps into the Okavango a vast area of the Kalahari is transformed into a fertile paradise. Nowhere on our planet Earth is the life giving power of water so clearly demonstrated. The Okavango becomes criss-crossed with trails as animals move into its heart. The new arrivals open up paths like arteries along which water flows, extending the reach of the flood. This is an Africa rarely seen - a lush water world. Some creatures are completely at home here. These are lechwe - antelope with hooves that splay widely, enabling them to move its speed through the water. For others the change is far less welcome. Baboons are somewhat apprehensive bathers. The water brings a season of plenty for all animals. Hunting dogs. These are now among the rarest of Africa's mammals, but then nonetheless thecontinent's most efficient predators. Their secret is teamwork. Impala are their favourite prey. They start to hunt and the pack splits up. An aerial viewpoint gives a new insight into their strategy. As the dogs approach their prey they peel off to take up separate positions around their target. They seem to form a cordon around the impala. Moving in total silence they take up their positions. Those ears can detect the slightest rustle. The hunt is on. Three dogs close in on one impala. Missed. The lead dog drives the impala towards the hidden flankers. Anticipating their line the leader cuts the corner and joins a flanker for the final assault. It's all or nothing. One on one. The dog has stamina, the impala has speed. Leaping into the lake is an act of desperation - impala can barely swim. The dogs know their prey must come out or drown - now it's a waiting game. The rest of the pack are calling. They've made a kill in the forest and this is an invitation to join in the meal. The impala is in luck. A pack this size kills once a day and everything is shared. And this impala is reprieved. The elephants are nearing the end of their long journey. After weeks ofmarching they're desperately tired. The matriarch can smell water and encourages the herd to make one last effort. The youngsters are exhausted but their mothers have made this journey before and they know that they're close to water. After many hundreds of miles they've arrived. The lives of these elephants are dominated by the annual rhythm of wet and dry, a seasonal cycle created by the sun. At the southern end of the earth, after four months of total darkness, the sun once more rises over Antarctica. Now at last the Emperor penguins abandon their huddle. The males are still carrying the precious eggs that they've cherished throughout the Antarctic winter. With thereturning sun the eggs hatch. Other birds have not even arrived. but the Emperors by enduring the long black winter have given their chicks a head start. These youngsters are now ready and eager to make the most of the brief Antarctic summer.第2集PLANET EARTH MountainsHuman beings venture into the highest parts of our planet at their peril. Some might think that by climbing a great mountain they have somehow conquered it, but we can only be visitors here. This is a frozen alien world. This is the other extreme - one of the lowest hottest places on Earth. It'sover a hundred metres below the level of the sea. But here a mountain is in gestation. Pools of sulphuric acid are indications that deep underground there are titanic stirrings. This is the Danakil Depression in Ethiopia, lying within a colossal rent of the earth's surface where giant land masses are pulling away from one another. Lava rises to the surface through this crack in the crust creating a chain of young volcanoes. This one, Erta Ale, is today the longest continually erupting volcano on the planet, a lake of lava that has been molten for over a hundred years. These same volcanic forces also created Ethiopia's highlands. 70 million years ago this land was just as flat and as deep as the Danakil Depression. Molten lava rising from the earth's core forced up a huge dome of rock 500 miles wide, the roof of Africa. Over millennia, rain and ice carved the rock into a landscape of spires and canyons. These summits, nearly 3 miles up, are home to some very remarkable mountaineers Gelada baboons. They are unique to the highlands of Ethiopia. The cliffs where they sleep are for expert climbers only, and Gelado certainly have the right equipment. the strongest fingers of any primate and an utterly fearless disposition. But you need more than a head for heightsto survive up here. A day in a Gelado's life reveals how they've risen to the challenge. For all monkeys morning is grooming time, a chance to catch up with friends. But, unlike other monkeys, Gelados chatter constantly while they do it. It's a great way to network while your hands are busy.But these socials can't go on for too long. Gelados have a busy daily schedule and there's work to be done. Most monkeys couldn't live up here. There's no food and few insects to feed on. But Gelados are unique they're the only monkeys in the world that live almost entirely on grass. They live in the largest assemblies formed by any monkeys. Some groups are 800 strong and they crop the high meadows like herds of wildebeest. The Gelados graze alongside Walia ibex, which are also unique to these highlands. These rare creatures are usually very shy but they drop their guard when the Gelados are around. You might expect that grazers would avoid each other's patch but this is a special alliance from which both partners benefit. It's not so risky to put your head down if others are on the lookout. Ethiopian wolves - they won't attempt an attack in broad daylight. But at dusk the plateau becomes a more dangerous place. With the grazing largely over there's a last chance to socialise before returning to the sleeping cliffs. An early warning system puts everyone on the alert. Their day ends as it began, safe on the steep cliffs. The Ethiopian volcanoes are dormant, but elsewhere others still rage. V olcanoes form the backbone of the longest mountain chain on our planet - the Andes of South America. This vast range stretches 5,000 miles from the Equator down to the Antarctic. It formed as the floor of the Pacific Ocean slid beneath the South American continent, buckling its edge. At the southern end stand the mountains of Patagonia. It's high summer, but theAndeshave the most unstable mountain weather on the planet and storms can erupt without warning. T emperatures plummet and guanacos and their newborn young must suddenly endure a blizzard. Truly, all seasons in one day... A puma - the lion of the Andes. Pumas are usually solitary and secretive. To see a group walking boldly in the open is extremely rare. It's a family - a mother with four cubs. She has just one brief summer in which to teach them their mountain survival techniques. Rearing four cubs to this age is an exceptional feat, but she does have an excellent territory, rich in food and water. Although the cubs are now as large as their mother, they still rely on her for their food. It will be another year before the cubs can hunt for themselves. Without their mother's skill and experience they would never survive their first winter. Battered by hurricane force winds, these slopes are now lifeless. Further north, they hold other dangers. Moving at 250 miles an hour, an avalanche destroys everything in its path. In the American Rockies a 100,000 avalanches devastate the slopes every winter. This huge mountain chain continues the great spine that runs from Patagonia to Alaska. The slopes of the Rockies, bleak though they are, provide a winter refuge for some animals. A mother grizzly emerges from her den after six months' dozing underground. Her two cubs follow her and take their first steps in the outside world. These steep slopes provide a sanctuary for the cubs. A male bear would kill and eat them given the chance. But big animals findit difficult to get about here. Males may be twice the size of a female and even she can have problems. Her cubs, however, make light of the snow and of life in general. But the mother faces a dilemma: it's six months since she last fed and her milk isstarting to run dry. She must soon leave the safety of these nursery slopes and lead her cubs away from the mountain. If she delays, the whole family will risk starvation. Summer reveals the true nature of the Rockies. Stripped of snow, the peaks bear their sculpted forms. Only now can mountaineers reclaim the upper reaches. Two miles up the crumbling precipices seem devoid of life. But there are animals here - a grizzly bear. It seems to be an odd creature to find on these high rocky slopes. It's hard to imagine what could have attracted it here. At this time of the year bears should be fattening up for the winter. Yet they gather in some numbers on these apparently barren slopes. They're searching for a rather unusual food - moths. Millions have flown up here to escape the heat of the lowlands and they're now roosting among the rocks. Moths may seem a meager meal for a bear, but their bodies are rich in fat and can make all the difference in a bear's annual struggle for survival. Another battle is being waged here but on a much longer timescale. These loose boulders are the mountain's crumbling bones. The Rockies are no longer rising but slowly disintegrating. All mountains everywhere are being worn down by frost, snow and ice. The Alps were raised some 15 million years ago as Africa, drifting northwards, collided with the southern edge of Europe. These spires are the eroded remains of an ancient seabed that once stretched between the two continents. But these are just the Alpine foothills. The range at its centre rises to 3 miles high and is crowned with permanent snows. The Matterhorn, its summit too steep to hold a snow field. Mont Blanc - the highest peak in Western Europe. The distinctive jagged shapes of the Alps were carved by those great mountain sculptors - the glaciers. Immense rivers of moving ice, laden with rock, grind their way down themountains, gouging out deep valleys. They're the most powerful erosive force on our planet. A moulin - a shaft in the ice opened by melt water as it plunges into the depths of the glacier. Like the water running through it, the ice itself is constantly moving, flowing down the valley with unstoppable force. Alpine glaciers may seem immense, but they're dwarfed by those in the great ranges that divide the Indian subcontinent from Tibet. This is the boulder strewn snout of the giant Baltoro glacier in the Karakoram mountains of Pakistan. It's the biggest mountain glacier on Earth - 43 miles long and over 3 miles wide. This huge ice-filled valley is so large it's clearly visible from space. This is the greatest concentration of peaks over 5 miles high to be found anywhere on Earth. They're the most dangerous mountains of all. K2 and her sister peaks have claimed more lives than any others. The peaks here rise so precipitously, the glaciers are so steep and crevassed that few except the most skilledmountaineers can penetrate these ranges. Markhor gather for their annual rut. Males must fight for the right to breed, but on these sheer cliffs any slip by either animal could be fatal. A snow leopard - the rarest of Himalayan animals. It's a female returning to her lair. These are the first intimate images of snow leopard ever filmed in the wild. She greets her one year old cub. Her den is well chosen. It has exceptional views of the surrounding cliffs. On these treacherous slopes no hunter other than the snow leopard would have a chance of catching such fragile prey. A female with young makes an easier target. Her large paws give an excellent grip and that long tail helps her balance. Silently she positions herself above her prey. She returns with nothing. Golden eagles patrol these cliffs in search of the weak or injured. With a 2 metre wing span this bird could easilytake a young markhor. Eagles hunt by sight and the thickening veil of snow forces them to give up. For the leopard the snow provides cover and creates an opportunity. The worsening weather dampens the sound of her approach allowing her to get within striking distance. It was an act of desperation to try and catch such a large animal. Wolves have made a kill giving other hunters a chance to scavenge. The worst of the blizzard brings success for the snow leopard, but having descended so far to make the kill she has a grueling climb to get back to her lair. The cub must be patient. It'll be a year before it has the strength and skill to kill for itself on these difficult slopes. The snow leopard is analmost mythical creature, an icon of the wilderness, an animal few humans have ever glimpsed for its world is one we seldom visit. The Karakoram lie at the western end of a range that stretches across a tenth of our planet - the Himalayas. These, the highest mountains of the world, like other great ranges, were created by the collision of continents. Some 50 million years ago India collided with Tibet thrusting up these immense peaks, which are still rising. This vast barrier of rock and ice is so colossal it shapes the world's climate. Warm winds from India, full of moisture, are forced upwards by the Himalayas. As the air rises so it cools, causing clouds to form and the monsoon is born. At high altitudes the monsoon rains fall as snow. Here, at the far eastern end of the range in China, one inhabitant endures the bitter winters out in the open. Most other bears would be sleeping underground by now, but the giant panda can't fatten up enough to hibernate. Its food, bamboo, on which it totally relies has so little nutritional value that it can't build up a store of fat like other bears. Most of the creatures here move up or downthe slopes with the seasons but the panda is held captive by its diet for the kind of bamboo it eats only grows at this altitude. But these forests hold fewer challenges for the more mobile. The golden snap-nosed monkey, like the giant panda, lives only in China. Their thick fur allows them to survive at greater altitudes than any other monkey and when the cold bites they have these upper slopes to themselves. Even if you have a warm coat it apparently helps to surround yourself with as many layers as possible. But at least these monkeys have a choice - if they tire of tree bark and other survival food they can always descend to lower warmer altitudes and not return there till spring. As the snows retreat trees come into bloom. Cherry blossom. Rhododendrons - here in their natural home they form great forests and fill the landscape with the covers of a new season. These forests are a host to a rich variety of springtime migrants. Beneath the blooms - another display. It's the mating season for oriental pheasants, Himalayan monal, tragopan and blood pheasant. Musk deer make the most of a short flash of spring foods. This male smells a potential mate. The red panda, rarely glimpsed in the wild. It was once considered a kind of raccoon, but is now believed to be a small mountain bear. By midsummer its larger, more famous relative, has retreated into a cave. A giant panda nurses a tiny week old baby. Her tender cleaning wards off infection. She won't leave this cave for three weeks, not while her cub is so utterly helpless. Progress is slow for milk produced on a diet of bamboo is wretchedly poor. Four weeks old and the cub is still blind. Its eyes do not fully open until three months after birth, but the chances of the cub reaching adulthood are slim. The struggle of a giant panda mother to raise her cub is a touching symbol of the precariousness of life in the mountains.。

Polar day 极昼
Polar bears北极熊
It’s march. And light returns to high Arctic, a Polar bear stirs from her den. Her emergence marks the beginning of spring. And the little bears come to their mother to get food. Their mother that has not eaten for 5 months and has lost half her body weight converts the last of her fat reserves into milk for her babies. Temperature -30 . The babies still need to live in the shelter. The sun will dissolve the ice, which will hinder the bear to hunt its food(seal). Nearly half of the baby bears will die in the first year in the broken ice.

The Amur leopard-the rarest cat in the world, syblolize the fragility of our nature heritage. There are only 40 Amur leopards left in the wild. And that number is falling. The cats has been pushed to the very edge of extinction by hunting and the destruction of their habitat.
All animals, rare or common, ultimately depend for their energy on the sun.

Birds of paradise
In the tropics the sun’s rays strike the earth head on, so the jungle grows so vigorously and supports so much life. This forest covers only 3 percent of the planet’s surface, but it contains more than 50 percent of all its plants and animals. There are 42 different species of birds of paradise living in the great island of New Guinea, each more bizarre than the last.

caribou北美驯鹿
Northern Canada’s wild frontier Every year 3 millions of caribou migrate across the Arctic tundra(北极苔原）. This is the longest over land migration made by any animal. Some herds travels over 2000 miles a year in search of fresh pastures. This is the longest overland migration made by any animal. There are wolves in hanger scheming to catch the newly born calves. The strategy is that running direcrly at the herd to make them in panic first , and then try to capture the separated the herd. And now it’s easier to target an individual. Midsummer on tundra and the sun does not set. As these latitudes the sun’s rays are glancing. And not enough of their energy reaches the ground to enable trees to grow.
