俯瞰我们的星球，可能会令人惊叹不已 Looking down on our planet, it may come as a surprise
我们可以找到很多被冰雪覆盖的大陆 to find just how much of it is blanketed in snow and ice.
这些广阔的冰冻荒野，涵盖了地球五分之一以上的面积... These vast frozen wildernesses cover more than a fifth of our planet
即使在今天，有些地区还是如此的偏远和荒凉， ...yet some areas are so remote and inhospitable that, even today,
我们从空中近距离地探索它们的神秘 the closest we've come to exploring them is from space.
十多年前，《冰冻星球》系列的第一部 More than a decade ago, the first series of Frozen Planet
探秘了北极和南极的生命 examined life in the Arctic and the Antarctic.
在本系列中，我们将探索地球上更多的冰冻栖息地... In this series, we will explore all of Earth's frozen habitats...
...从最高山峰， ...from its highest peaks,
到白雪皑皑的沙漠... to its snowbound deserts...
...再到冰层深处 ...to deep beneath the ice.
在它们中间，生活着一系列惊人的动物... Between them, they contain an astonishing array of animals...
...在地球上其他地方，是绝无仅有的 ...many that are found nowhere else on Earth.
我们将观看到动物生存的非凡努力 We will watch the extraordinary ways
动物们一直设法生存 by which they manage to survive.
摄制组使用新技术，如赛车遥控式无人机， Using new technology, such as racer drones,
我们将会对动物们不平凡的生活有全新的认识 we'll gain a new insight into their remarkable lives.
但就在我们开始了解野生动物时， But just as we're beginning to understand its wildlife,
我们正在认识到一个令人震惊的事实 we are recognising an alarming truth.
我们冰冻的荒野正在不断消失 Our frozen wildernesses are disappearing
以比往更快的速度消失 at faster rates than ever before.
了解清楚这些冰冷的地区发生的事， And never has it been more important to understand
从未像现在如此重要 what is going on in these icy territories.
在第一集中，我们将从一个极点到另一个极点…… In this first episode, we will travel from pole to pole...
...庆贺还有一些珍贵的野生动物 ...to celebrate the precious wildlife
在冰冻的荒野中，能够被我们发现... found in our frozen wildernesses...
...并见证它们的奇迹... ...and witness their wonders...
但是任有时间来拯救这些野生动物 ...while there is still time to save them.
冰 冻 星 球 Ⅱ
从地球的最南端开始我们的旅程 We begin our journey in the far south of the planet.
经过六个月的黑暗，太阳开始回归 After six months of darkness, the sun is starting to return
重新照耀地球上最大的冰冻地带…… to the largest frozen expanse on Earth...
...南极洲 - ...Antarctica -
这块陆地，几乎是澳大利亚的两倍 a continent almost twice the size of Australia.
冰 冻 世 界
在这里，气温能低至-80摄氏度 Here, temperatures fall to - 80 degrees centigrade.
是地球上最冷的地方 It's the coldest place on Earth.
有一种动物非常耐寒 There is only one animal here hardy enough
在冬天里繁衍后代... to raise its family in winter...
...帝企鹅 ...the emperor penguin.
这里的风速可以超过160km/小时， Winds here can reach speeds of over 100 miles an hour
小企鹅真有冻死的危险 and a chick is in real danger of freezing to death.
但它的父母可能是自然界中最挚爱的 But his parents are possibly the most devoted in all nature.
它们全力保护小企鹅免受冰冷打击... They shield him from the full force of the icy blast...
...小企鹅们挤在一起，形成一个紧密的托儿所 ...and huddle together to create a tight creche.
很明显，小企鹅在其中可以保持体温 Within it, the chicks, remarkably, can maintain their body temperature
正常的37摄氏度 of 37 degrees Celsius.
直到某个春天的某一天， Until one spring day,
当小企鹅长到差不多一米高的时候... when the chicks have grown to almost a metre tall...
...父母默默地走开 ...the parents simply walk away.
作为父母的职责已经完成... Their parental duties are complete...
...企鹅妈妈们，永远不会再回到小企鹅身边 ...and they will never again return to their chicks.
日子一天天过去，小企鹅们越来越饿... As the days pass, the chicks grow hungry...
唯一能找到食物的机会，就是在大海里... And their only chance of finding a meal is out at sea...
...但那是在 30 英里开外的冰冻海洋 ...but that could be 30 miles away across the frozen ocean.
当有一个小企鹅做出第一个大胆的举动时... When one makes the first bold move...
...其余的紧随其后 ...the rest follow.
小企鹅们以稳健的步伐出发 They set off at a steady pace.
用腹部滑行，是一个简单的选择 But sliding on your belly is an easy option.
在这个不断变化的冰冻海平台上... Out on this ever-changing platform of the frozen sea...
...高耸的冰墙挡住了小企鹅们的去路 ...towering walls of ice stand in their way.
这需要登山技巧 This will require mountaineering skills.
喙作为冰镐很有用 Beaks come in useful as ice-picks.
雪橇滑行是一种快速下降的方式 And tobogganing is a quick way down.
当靠近大海时，冰变得更加不稳定 As they near the sea, the ice becomes more unstable.
即使是最小的裂缝也值得注意 Even the smallest crack is met with suspicion.
并且有充分的理由 And with good reason.
裂缝可以很快变成一个巨大的鸿沟 A crack can quickly turn into a gaping chasm.
如果无法逃出，惊慌失措的小企鹅将注定无法生存 If they can't escape, the panicked chicks will be doomed.
出来了 Made it.
终于，目标在望 Finally, the end is in sight.
南大洋 The Southern Ocean.
在某些年份，海冰非常不稳定 In some years, the sea ice is so unstable
不是所有的都能做到这一点 that none make it as far as this.
这些小企鹅是幸运的 These chicks are the lucky ones.
虽然入水不是最优雅的 Not the most graceful entry.
但是，小企鹅来到了适宜的环境... But they are in their element...
...蔚蓝的大海 ...the sea.
它们可能经历了最艰难的成长， They may have endured the toughest of upbringings,
但现在它们可以从未来漫长的夏天中获益 but now they can reap the benefits of the long summer ahead
并以在地球上最丰产的水域觅食 and feed in the richest waters on Earth.
冬天，南极洲周围的海域很寒冷 In winter, the seas around Antarctica are so cold
这里形成了一个两倍于欧洲大小的冰平台 that they form a platform of ice twice the size of Europe.
但在夏天，南极半岛的海岸附近， But in summer, just off the shores of the Antarctic Peninsula,
冰盖分解成数百万个小的浮冰块 the ice cover breaks up into millions of tiny ice floes.
这是威德尔海豹的绝佳去处 It's an excellent place for a Weddell seal
晚饭吃饱后休息 to rest up after a night's feed.
海湾提供了方便... The bay is sheltered...
...水面很平静 ...and the water calm.
但这里藏有很大的危险 But there are great dangers here.
虎鲸 Killer whales.
这双 15 岁的年轻虎鲸，正在学习可能是 This pair of 15-year-olds are learning what is perhaps
自然界中最复杂的狩猎技术 the most complex hunting technique in nature.
在对猎物进行估量后... After sizing up their prey...
...它们在 30 米外集合... ...they assemble 30 metres away...
...然后发动攻击 ...and then launch an attack.
虎鲸一起游泳，尾巴同步摆动... They swim in tandem, synchronising their tail beats...
...掀起一个波浪 ...to create a wave.
海豹被冲下冰块... The seal is washed off...
...但海豹不会就此不战而降 ...but it won't give up without a fight.
海豹逃脱了... The seal has escaped...
...这次很侥幸 ...this time.
但对于年轻的虎鲸来说，后援就在旁边 But for the young killer whales, help is at hand.
虎鲸生活在多代共存的家庭之中... They live in multi-generational family groups...
...由一位经验丰富的雌性领导，她可以超过 100 岁 ...led by an experienced female, who can be over 100 years old.
在她积累的知识的帮助下， Helped by her accumulated knowledge,
虎鲸变得无情和高效 the whales have become ruthlessly efficient.
它们有高达 90% 的狩猎成功率 They have a 90% hunting success rate.
但是虎鲸一天要吃一只海豹... But a killer whale needs to eat a seal a day...
...所以这个 14 口的家庭要进行很多次狩猎 ...so this 14-strong family has a lot of hunting to do.
它们四散开来，搜寻浮冰 Spreading out, they spyhop to search the ice floes.
当发现海豹时， When a seal is spotted,
侦察兵发出召集声，提醒家人 the scouts alert the family with a rallying call.
如果它们要抓到一只休息的海豹 But if they are to catch a seal resting on
面对这么大一块冰... such a large piece of ice...
...猎人们需要改变它们的战术 ...the hunters need to change their tactics.
这一次，虎鲸集体产生了次表面波 This time, they produce a sub-surface wave.
它将冰块破碎成更小的碎片 It breaks the ice into smaller pieces.
但是海豹还是在浮冰之上... But the seal still has a raft...
...似乎，面对任何迎面而来的波浪，可以受到保护 ...and appears to be protected from any oncoming wave.
然而，虎鲸女族长有个办法 The matriarch whale, however, has a plan.
采用相互合作的方式工作， Working in a coordinated way,
鲸群合力推动海豹的冰台 the pod push the seal's ice platform
进入少冰的水中 into clearer water.
女族长现在又尝试一种策略 The matriarch now tries another tactic
这样可以避免受伤... which will avoid injury...
...吹泡泡 ...blowing bubbles.
终于使疲惫的海豹迷失方向 They disorientate the tiring seal.
鲸鱼开始杀戮。 And the whales move in for the kill.
世界上只有大约 100 头虎鲸使用这种技术捕猎 Only about 100 killer whales in the world hunt using this technique.
这是获得猎物的巧妙解决方案 It's an ingenious solution to the problem of finding prey
这里是地球上最极端的冰冻栖息地 here in the most extreme frozen habitat on Earth.
南极这么冷 Antarctica is so cold
因为它位于地球的最南端 because of its position at the far south of the planet.
但是向北走，你会发现其他冰天雪地的世界 But travel north, and you'll find other icy worlds
有的由海拔高度造成的 - 在高山区 that are created by altitude - in the mountains.
南美洲的安第斯山脉， The Andes, in South America,
拥有 4,500 英里白雪覆盖的山峰， with its 4,500 miles of snow-covered peaks,
是地球上最长的山脉 is the longest range on Earth.
这些非常冰冷的世界甚至存在于赤道附近， These high icy worlds even exist close to the equator,
--太阳最强烈的地方，如同非洲的肯尼亚山 where the sun is at its hottest - as on Mount Kenya, in Africa.
但最高的山脉绵延 1,500 英里 But the highest mountains of all stretch 1,500 miles across
亚洲亚热带北部--喜马拉雅山脉 the north of sub-tropical Asia - the Himalaya.
在其西面，与巴基斯坦接壤， At the western end, bordering Pakistan,
耸立着喀喇昆仑山 stand the Karakoram.
它们包含很多超过 8,000 米高的山峰 They contain more peaks over 8,000 metres high
比地球上任何其他山区的都多... than any other range on Earth...
...并包括高 8,600 米的 乔戈里峰 ...and include K2, which stands over 8,600 metres tall.
喜马拉雅山坡的冰雪堆积量是最大的 The slopes of the Himalaya carry the greatest accumulation
--除极地以外 of snow and ice outside the polar regions.
这个地区被称为第三极 It's an area known as the Third Pole.
但在喜马拉雅山以北， But north of the Himalaya,
很高的海拔创造了更令人惊讶的冰雪世界 there are even more surprising frozen worlds created by altitude.
边远的白雪皑皑的沙漠... A remote snow-bound desert...
...戈壁 ...the Gobi.
再往前是一片绵延的草地 And beyond it, a grassy plain that stretches
横跨中亚5,000英里 for 5,000 miles across Central Asia.
被称为大草原 It's known as the Great Steppe.
这里，在巨石巢穴中，有一只躲避恶劣的条件的 Here, sheltering from the elements in his boulder den,
一个有点不开心的居民 is a somewhat grouchy resident.
帕拉斯的猫 A Pallas's cat.
它拥有世界上所有猫科动物中最浓密的绒毛 He has the densest fur of any cat in the world.
尽管如此，为了保暖，它每天必须捕捉多达五只啮齿动物 Nonetheless, to keep warm, he must catch up to five rodents a day.
菜单的第一条是田鼠... Top of the menu are voles...
...还有沙鼠 ...and gerbils.
相对比较同类体型， Relative to body size,
帕拉斯的猫是所有猫中腿最短的... Pallas's cats have one of the shortest legs of any cat...
...这有助于在跟踪猎物时保持低体位 ...and that helps by giving them a low profile when stalking.
但它不适合涉过深雪 But it's not so good for wading through deep snow.
没关系，还有很多 Never mind. There are plenty more.
它只需要保持专注 He just needs to stay focused.
遗憾的是，它在雪地里待的时间越长， Unfortunately, the longer he's out in the snow,
它的爪子越冷 the colder his paws become.
只有一种方法可以让血液再次循环 And he has only one way to get the blood circulating again.
这可能是抖得太多了 That could be one shake too many.
帕拉斯的猫只有三分之一的狩猎成功率 Only one hunt in three by a Pallas's cat is successful.
难怪它享有盛誉 No wonder he has the reputation of being
“世界上最坏脾气的猫” the grumpiest cat in the world.
在草原的北部，在高纬度地区， To the north of the steppe, in higher latitudes,
是另一个冰冻的世界 lies yet another frozen world.
北方森林 The boreal forest.
7500 亿棵白雪覆盖的树木 750 billion snow-covered trees.
它是地球上最大的森林， It's the largest forest on Earth,
环绕世界之巅 encircling the top of the world
从欧洲到俄罗斯， from Europe to Russia,
并穿越到北美 and across to North America.
在这片广阔的西伯利亚森林的最东端 At the far eastern end of this vast Siberian forest
是世界上最稀有的大型猫科动物之一的狩猎场 lies the hunting ground of one of the world's rarest big cats.
西伯利亚虎（东北虎） The Siberian tiger.
非法狩猎和其栖息地的破坏 Illegal hunting and destruction of its habitat
把这里的老虎逼到了灭绝的边缘 have driven this tiger to the very brink of extinction.
现在只有不到 500 只，在野外生存 Now fewer than 500 remain in the wild.
它重近 200 公斤，是所有大型猫科动物中最大的 Weighing nearly 200kg, it's the largest of all the big cats.
为了保持体温，这只雄性每天必须吃掉10公斤肉 To keep warm, this male must eat 10kg of meat a day.
在冬天，一些猎物仍然留在这里... But in winter, any prey remaining here...
...太容易受惊了 ...is all too easily alarmed.
它必须巡逻它整个 700 平方英里的领土 He must patrol his entire 700 square mile territory
--才能找到足够的食物 if he is to find enough to eat.
猪哼着鼻子 PIGS SNORTING
敏锐的嗅觉告诉它，野猪在这里 His acute sense of smell tells him that wild pig were here.
它饿得连一头150公斤重的黑熊都吃得下 He's so hungry that he would tackle even a 150kg black bear.
但熊几个月前就离开了这里... But it left here months ago...
...只留下一丝淡淡的气味 ...leaving only a faint trace of its scent.
秋天，这里的熊躲避即将到来的冬天 In the autumn, bears here escape the coming winter
进入洞穴冬眠 by hibernating inside caves.
但这并不能阻止老虎试图抓住一只熊 But that wouldn't stop a tiger from trying to catch one.
远程摄像机揭示了熊的去向 Remote cameras reveal the bear's whereabouts.
几个月前，它退入到最远的隐蔽处 It retreated into the farthest recess months ago.
老虎实在太大了，进不去 The tiger is simply too big to reach it.
但随时准备把握每一个机会， But ready for every opportunity,
这只大猫能够忍受漫长的西伯利亚冬天 this big cat is able to endure the long Siberian winter.
只要这片森林没有偷猎者， And as long as this forest is kept free from poachers,
这些出色的的老虎有很大的生存机会 these magnificent tigers have a good chance of surviving.
在北方森林的北部... In the northerly reaches of the boreal forest...
...一种奇怪的现象照亮了夜空 ...a strange phenomenon illuminates the night sky.
北极光 The Aurora borealis.
来自太阳的带电粒子 Electrically charged particles from the sun
与地球大气层摩擦， collide with the Earth's atmosphere,
创造这个超凡脱俗的光影展示 creating this otherworldly display.
从空中鸟瞰，极光为冰冻的两极带来光明， Viewed from space, the aurora brings light to the frozen poles,
否则极地将在黑暗中停留近三个月 which otherwise would remain in darkness for almost three months.
这是北极苔原... This is the Arctic tundra...
...温度可能会降至 -50 摄氏度 ...where temperatures can fall to - 50 degrees Celsius.
几乎没有庇护所， With little or no shelter,
很少有动物能在这里过冬 few animals can survive the winter here.
但有些动物能够做到 But some do.
麝牛 Muskox.
上一个冰河时代的遗迹 Relics from the last ice age.
两层毛发能够保护它们免受-30度的酷寒伤害 Two layers of fur protect them from temperatures of -30 degrees.
这使麝牛可以在早春分娩 This allows them to give birth in early spring.
出生六小时的小牛已经能够站立... At six hours old, a calf is already able to stand...
...准备跟随牛群寻找新鲜的牧草 ...ready to follow the herd in the search for fresh grazing.
但在小牛获得力量之前， But until they gain in strength,
非常脆弱 they are very vulnerable.
牛群正在被跟踪 They're being stalked.
一只灰熊 Grizzly bears.
体重达300公斤， Weighing up to 300kg,
它们在冬眠六个月后出来了... they have emerged after six months of hibernation...
...而且非常饿 ...and are extremely hungry.
一只熊就在十米之内... One gets to within just ten metres...
...然后攻击 ...and then attacks.
小牛与母亲分离， Separated from their mothers,
刚出生的小牛分不清是朋友... the newly born are unable to distinguish friend...
...还是敌人 ...from foe.
熊本能地杀死了它可以杀死的每一头动物 The bear instinctively kills every calf it can.
只有少数小牛能够逃脱 Only a few escape.
但是现在牛群已经走远了... But the herd is now far away...
...太虚弱了，无法跟随 ...and he is too weak to follow.
90% 的小牛活不过第一年 90% of calves do not survive their first year.
即使没有受伤的小牛，如果没有母亲，也几乎没有生存机会 Even one without injury stands little chance without its mother.
重聚 ！ Reunited.
如果只有几头小牛能活到成年， If just a few calves survive to adulthood,
牛群的未来，也将是有保障的 the future of the herd will be secure.
苔原以北是北冰洋， North of the tundra lies the Arctic Ocean,
被三大洲包围-- surrounded by three continents -
欧洲、北美洲和亚洲 Europe, North America and Asia.
冬天，它几乎完全冻结 In winter, it remains almost entirely frozen.
但随着春天的阳光，终于到达地球上的最北端 But as the spring sunshine finally reaches the northernmost part
海冰开始破裂 of the planet, the sea ice begins to break up.
这标志着繁殖季节的开始 This marks the start of the breeding season
--对于雄性冠海豹而言 for male hooded seals.
当它们六岁时，雄性会长出一个可充气鼻子 When they're six years old, the males develop an inflatable nose.
它们已经准备好繁殖-- They're ready to breed -
鼻子越大， and the bigger their nose,
对雌性越有吸引力 the more attractive they will be to a female.
而现在这只冠海豹急于证明这一点 And now this one is eager to prove it.
一只雌性刚生完孩子 A female has just given birth.
一位母亲只花了四天时间给她的幼崽喂奶... A mother spends a mere four days feeding milk to her pup...
...然后到那时，也只有到那时，她才能准备好再次交配 ...and then, and only then, will she be ready to mate again.
对于一个没有耐心的年轻人来说，等待的时间太长了 That is too long for an impatient youngster to wait around.
这些雌性似乎正被一个更大的雄性占据 These females seem to have been claimed by a larger male.
但如果这位年轻海豹今年就繁殖，值得一试 But if this youngster is to breed this year, it's worth a try.
也可以使用充气鼻子 An inflatable nose can also be used
恐吓对手 to intimidate a rival.
它的虚张声势得到了回报 His bravado pays off.
现在必须向善于倾听的雌性求爱 He must now woo the receptive female.
她似乎不为所动 She seems unimpressed.
但它还有另一个技巧 But he has another trick.
它的左鼻孔内有一个可扩张的囊 He has an expandable sac within his left nostril.
她的最终决定是什么？ What is her verdict?
雄海豹的尾巴上被狠狠咬了一口... A sharp nip on the tail...
...这意味着不行 ...and that means no.
一年中只有一天可以交配， With only one day in the year in which to mate,
可以理解，雌性的挑剔 the female is understandably choosy.
直到这个年轻人长出一个更令人印象深刻的冠状鼻， And until the youngster has grown a more impressive balloon,
否则，它不太可能被选中 he's unlikely to be chosen.
海豹呻吟 SEAL GROANS
难怪它泄气了 No wonder he's deflated.
春天不仅改变了海洋， The spring not only transforms the ocean,
它还触发了一个重要事件 it also triggers an important event
在北极最大的岛屿上 on the biggest of the Arctic's islands.
格陵兰 - 超过 1,600 英里长 Greenland - over 1,600 miles long.
它被一个巨大的冰盖覆盖， It's covered by a single gigantic ice sheet,
北半球最大的 the largest in the northern hemisphere.
随着春天的到来，冰面融化， As spring advances, the surface of the ice melts,
形成晶莹剔透的湖泊... forming crystal-clear lakes...
...宽达五英里 ...up to five miles wide.
气候变化带来更高的温度， Climate change is bringing higher temperatures,
所以融水越来越多 so there is more and more meltwater.
它流入一英里厚的冰盖... It drains down into the mile-thick ice sheet...
...然后触发整个事件链 ...and a whole chain of events is then triggered.
太空延时摄影揭示了接下来会发生什么 Time-lapse photography from space reveals what happens next.
增加的融水加速了冰盖滑下山坡 The increased meltwater accelerates the ice sheet's slide downhill.
最终，冰盖到达了海洋 Eventually, it reaches the ocean.
在这里，它裂解成冰山， Here, it breaks up into icebergs,
比帝国大厦还要高一些 some taller than the Empire State Building.
格陵兰岛今天的冰川流失速度 Greenland is losing its ice six times faster today
比30年前快了六倍 than it was 30 years ago.
它独自分摊 It alone is responsible for a quarter
全球海平面上升的四分之一 of the rise in global sea levels.
北极的变化，已经在影响动物们的生活 Changes in the Arctic are already affecting the lives
包括对这种高度专业的野生动物 of its highly specialised wildlife.
北极熊 Polar bears.
这对一岁的双胞胎仍然依靠母亲的乳汁、 These one year old twins still rely on their mother for her milk,
以及母亲的保护和重要的生存课 protection and crucial survival lessons.
但是它们还没有完善自己的游泳技术... But they have yet to perfect their swimming technique...
...它们迫不及待地想要练习 ...and they can't wait to practise.
幼熊需要在水中像在家里一样 The cubs need to be as at home in the water
如同它们在海冰上一样 as they are on the sea ice.
它们的母亲叫它们出来 Their mother calls them out.
直到它们积累了大量的身体脂肪... Until they've accumulated a significant layer of body fat...
...否则，它们会感到寒冷 ...they feel the cold.
在雪地里打滚是擦干身体的好方法 A roll in the snow is a good way to dry off.
然后回去继续玩... Then it's back to play...
...当它们的母亲去打猎时 ...while their mother heads off to hunt.
在接下来的几个月里，母亲必须提供她的幼崽 Over the coming months, a mother must provide her cubs
不仅有乳汁，还要有肉-- with not just milk, but meat -
还需要很多 and lots of it.
到了盛夏，海冰变得如此稀薄... By midsummer, the sea ice has become so thin...
...她猎获喜爱猎物的最佳机会 ...that her best chance of catching her preferred prey
从水中伏击 is by ambushing it from the water.
这是一种被称为水下潜近的技术 It's a technique known as aquatic stalking.
她从下风口接近... She approaches downwind...
...并试图进入一只髯海豹一米之内 ...and tries to get within a metre of a bearded seal.
但是今天可以提供掩护的海冰越来越少， But today there is less sea ice to provide cover,
所以她不得不瞄准风险更大的猎物 so she is having to target riskier prey.
冠海豹 The hooded seal.
它们的大小和髯海豹差不多， They are about the same size as the bearded,
但更具侵略性和危险性 but more aggressive and dangerous.
她绕到另一边 She moves round to the other side.
北极现在变暖的速度是原来的两倍多 The Arctic is now warming more than twice as fast
和世界其他地方一样 as the rest of the world.
最早到 2035 年，海洋可能在夏季完全不结冰 The sea could be ice-free in summer by as early as 2035.
这将使北极熊妈妈更难 That will make it harder for mother polar bears
养活自己... to feed themselves...
...更不用说它们的幼崽了 ...let alone their cubs.
适合在寒冷的环境中生活的... Well adapted to live in the cold...
...栖息在我们冰冻的土地和海洋中的动物 ...the animals that inhabit our frozen lands and seas
比其他任何东西都需要的一件大事... need one thing more than any other...
...让地球停止变暖... ...and that is for the planet to stop warming.
现在需要由我们来实现这一点...... It's now up to us to make that happen.
