像如此雄伟壮观的自然景象 There are few truly wild places left
已经很少了 and none so majestic as this.
在冬天 北极光那活泼的舞蹈 In winter, endless darkness is brightened
照亮了无尽的黑暗 by the frisky dance of the northern lights.
零下三十度是正常的 And 30 below is the norm.
这对于北极熊一家来说 是个好天气 It's lovely weather for polar bear families.
十五万年前 One hundred and fifty thousand years ago
一些棕熊向北迁徙 some brown bears moved north and gradually adapted.
为了伪装 它们的皮毛随着时间的推移 Over time, their fur turned white
而变白 for camouflage.
它们的鼻子变长 Their snouts got longer
嗅觉更灵敏 and their noses keener
甚至有一丝气味的晚餐 它们也能察觉的到 to detect even the slightest whiff of dinner.
这是个异常寒冷的世界 This is a cold, stark world
但对于北极熊妈妈和它的幼崽来说 but to polar bear mothers and cubs
是它们的天堂 it's paradise.
因为它们在北极长大 Because they're built for the Arctic
北极熊不是在任何地方都可以繁衍生息的 polar bears cannot thrive anywhere else.
它们的家在这 也只有这里 They're at home here and only here.
北极熊总是 Polar bears have always hunted
在漂浮的海冰面上捕猎 from floating platforms of sea ice.
获取丰富的海豹肉盛宴 Feasting on rich seal meat
从而变成了世界上最大的熊 has made these the largest bears in the world.
但现在北极正逐渐变暖 But now the Arctic is warming
海冰也正在融化 and the sea ice is melting away.
想捕食到海豹也越来越困难了 making it harder than ever to catch seals.
这个变化 This warming
迫使北极熊离开了这片薄冰 has left the polar bears on thin ice.
少量的冰反射着太阳光线 The less ice there is to reflect the sun's rays
加快了海洋变暖 the faster the ocean warms.
这就是北极变暖的速度比其他任何地方都要快两倍的原因 That's why the Arctic is warming twice as fast as any other region.
在1980年 In 1980
夏季的海冰面覆盖了百分之25以上的海洋 the summer sea ice covered 25 percent more ocean
相比现在 than it does now.
如果目前的状况持续下去 If the current trend continues
到2050年 the Arctic Ocean could be free of sea ice each summer
每年夏天的北冰洋 将不在有海冰 by the year 2050.
即使我们不能阻止状态恶化 但我们可以缓解 Even if we can't stop this loss, we can slow it down.
正如我们在气候变暖的区域释放的温室气体 Just as we release the greenhouse gases that are warming the region
我们可以减少这些状况的发生 we can help reduce them.
来自北极的洋流涌动 Ocean currents flow from the Arctic
不仅冷却了整个地球 and cool the entire planet.
还与我们息息相关 So we're all closely connected to the top of the world.
与以往相比 大量的北极冰川正加剧融化 Most Arctic glaciers are melting faster than ever before.
讽刺的是 愈快的冰川融化 Ironically, the faster these glaciers melt
造就了愈多的冰川瀑布 the more majestic their waterfalls.
冰川之间的距离越来越大 The distance between ice packs is growing.
现如今 北极熊要走很长的路 才能搜寻到食物 Nowadays, a polar bear in search of sea ice often has further to go.
要游到很远 It can be a swim to nowhere.
当它们找不到海豹等食物时 When they can't find seals to eat
熊妈妈只好凑合着找一些东西来吃 mothers make do with meager scraps.
一个熊妈妈曾经带着熊宝宝 One mother and her cub set out on the longest swim ever tracked.
连续不停地游了9天 The mother swam continuously for nine days
路途长达430英里 covering 430 miles.
但她的宝宝没有坚持下来 But her cub did not survive.
一些幼崽活了下来 Some cubs do survive
这得益于熊妈妈如果是一个聪明的清道夫 especially if the mother is a clever scavenger.
像北极熊一样 Like polar bears
北极变暖下的鸟儿们也在努力生存着 birds are struggling as the Arctic warms.
北极鸟类在它们的季节生活着 Arctic birds time their lives to the seasons.
因纽特人也是如此 So do the Inuit people
就像Simon Qamanirq like Simon Qamanirq.
北极熊给我们的营地带来了惊喜 Polar bears surprise us in camp.
特别是在夏季的时候 Especially in the lean summer months.
我的父亲会看云向天气 My father could read the clouds.
他知道暴风雨何时来临 He knew when the storm was coming.
但现在古气候模式已发生改变 But now the ancient weather patterns have changed.
我们的祖父辈们 供养着他们的家庭 Our grandfathers fed their families well.
我的家人一直依赖于这冰和雪 My family has always depended on snow and ice.
如今冰雪逐渐融化时 我们可以适应调整 Nowadays when the ice melts, we can adjust
但北极熊们就没有这么幸运了 but the polar bears are not so lucky.
冰川将于今年晚些时候成型 The ice is forming later in the year
所以现在都是薄冰 so it's thinner.
有时我们会从这通过 Sometimes we fall through.
我的朋友Adam Ravetch为了拍摄动物 My friend Adam Ravetch has been coming up here for 20 years
已经在这里20年了 to photograph the animals.
我很喜欢看熊妈妈带着她两岁的幼崽 I love it when a mom dances with her 2-year-old cub
脸贴着脸的跳舞 cheek to cheek.
北极熊是个很好的游泳健将 Polar bears are great swimmers
即使它们 even though they only use
只用前爪游 their gigantic front paws.
这些专职妈妈为了抚养它们的孩子 These dedicated mothers put over two years
奉献了两年的青春时光 into raising their young.
海象妈妈则需要花费更长时间 Walrus moms spend even longer.
海象爱吃贝类 Walrus love clams.
它们从漂浮的冰面俯冲下来 They dive down from rafts of ice
随波逐流 并随时获取 which drift along and carry them to fresh supplies
它们最爱的新鲜食物 of their favorite treat.
海冰慢慢融化 As sea ice melts
海象被困在了陆地上 walrus are stuck on land
一些妈妈为了它们的孩子必须游到更远处来寻找食物 so mothers must swim farther to find food for their young.
妈妈教给它们的孩子生存技能 Mothers teach their young survival skills
例如吓跑入侵者 such as scaring off intruders.
一位妈妈传递给我一个明确的信息 One mom sent me a very clear message:
"迷路" "Get lost."
北极的夏天 持续长达一个月的时间 Summer in the Arctic now lasts about a month longer.
海象与饥饿的北极熊都在等待着 Walrus and hungry bears
等待着海面冻结 wait and wait for the sea to freeze over.
公熊变得浮躁 The males get restless
并开始互相打斗 and start sparring.
彼此之间互相试探着技巧 They're testing each other's skills.
这很有趣 It's fun.
当不在交配季节时 When it's not
这些竞争对手之间也会互相帮助 mating season, these fierce rivals are content to live and let live.
熊们必须夺回 The bears need
它们的狩猎场 现在的海面 to get back out to their hunting grounds now that the sea ice is
终于冻结了 finally freezing over.
水温冰冷异常 This water is literally as cold as ice.
盐阻止了海水的冻结 The salt keeps it from freezing.
这些海葵看起来很健康 These sea anemones look healthy.
但远在千里之外的我们释放的温室气体 But the greenhouse gases we release thousands of miles
所产生的大量酸性物质来到了这里 away have made the Arctic Ocean more acidic.
在这下面只有一条出口 Down here, there's only one exit
这是很恐怖的 想象一下 你可能会被困住 and it's pretty scary thinking you could be trapped.
冰面下潜水是需要一定勇气的 Diving beneath the ice takes courage.
但是为了人类 冒着生命危险来探索北极 But for the people who devote their lives to studying the Arctic
是他们工作的一部分 taking risks is part of the job.
在阿拉斯加的每年春季 Each spring in Alaska
大量成群的驯鹿在漫长的迁徙 large herds of caribou set out on a long journey.
从没有人跟踪过整个迁徙路线 No one has ever tracked the entire migration on foot
直到现在 until now.
Leanne Allison 一个制片人 Leanne Allison, a filmmaker
与 Karsten Heuer 一个生物学家 and Karsten Heuer, a biologist
计划随兽群生活五个月 plan to live with the herd for five months.
我们这次的旅程将追随母驯鹿经过的地方 We're gonna do this trip to see what the caribou mothers go through
并从它们的视角来观察此次迁徙 and to see this migration from their perspective.
这就像我们的蜜月一样 And it's gonna be our honeymoon as well.
度蜜月? Honeymoon?
这对新婚夫妇将跟随者驯鹿 These newlyweds will follow the caribou
一直到达它们的繁衍栖息地 all the way to their birthing grounds.
这些母驯鹿的日程很紧张 These caribou mothers are on a tight schedule.
是的 这肯定是驯鹿经过的地方 看看那些排水口 Yeah, that's gotta be caribou paths. Look at that drainage coming in.
是的 就在那 Yeah, just over there
随着春天的到来 积雪慢慢融化 With the warm spring, the snowpacks melted early.
到处都是河流 And so the rivers are flooding
这对于经过的驯鹿群会是个问题 and this is gonna be a problem for the caribou to get across.
这一气候变化拖慢了兽群的速度 This is climate change slowing down the herd.
异常冰冷的河水足矣让你的心跳停止 This water is so cold it can stop your heart.
我们需要快速的穿越过去 We've gotta get across fast.
母驯鹿路行几百里 The caribou moms are traveling hundreds of miles
到达阿拉斯加的沿海平原 to get to the coastal plain of Alaska
这是繁衍的最佳地点 which is the safest place to give birth.
今年的迁徙 晚了大约三周 This year the migration is about three weeks late
所以一些驯鹿妈妈 在沿途就生下了小宝宝 so some of the caribou mothers have to give birth along the way.
这些幼崽只有一到两周大 Some of these calves are just a week
很容易受到熊或者狼的捕食 or two old, and they're easy pickings for bears and wolves.
我们看到许多幼崽从它们的妈妈身边离开 We're seeing a lot of calves get separated from their mothers.
它们当中许多无法生存 A lot of them don't survive.
驯鹿最终到达它们的目的地 The caribou finally reach their goal.
这里就是幼崽们生存的最好的地方 This is the place where the calves have their best chance to survive.
但在它们出生后没几天 寄生虫胃蝇就孵化了 But just a few days after they give birth, the botflies hatch.
这对驯鹿来说 是致命的 These bugs are potentially deadly to these caribou.
它们会钻进驯鹿的鼻子里 将卵产在那 They can burrow up their noses, lay their eggs there
它们会引起兽群的踩踏 and they can set off stampedes.
这就是为什么驯鹿会离开那 朝山上走去 It's why caribou head for the high country: to get away.
由于北极变暖 母驯鹿将会度过很艰难的一段时间 Caribou mothers are having a tough time as the Arctic warms.
但北极熊妈妈将面临更大的挑战 But polar bear mothers face an even greater struggle.
为了更多的了解北极熊 To learn more about polar bears
一个团队的自然学家和制片人聚集在挪威的 a team of naturalists and filmmakers gathered on Svalbard Island
斯瓦尔巴群岛 in Norway.
他们找来了一个经验丰富的船长一同前往北极 They signed on with a seasoned captain and headed north.
我叫Bjorne Kvernmo My name is Bjorne Kvernmo
是这艘船的船长 and I'm captain of this ship.
在这个世界上有超过两万头的北极熊 There are over 20,000 polar bears in the world
大部分都不喜欢面对镜头 and most of them are camera-shy.
为了拍摄这些不情愿的电影明星 To photograph these reluctant film stars
John Downer将遥控摄像机 John Downer uses clever robotic cameras
伪装成了白色 camouflaged in white.
北极熊对这些摄像机充满了好奇 The bears were curious about the remote cameras.
一只熊比较容易拍到 One bear was especially helpful.
只有三个月大的小熊很难追上 It's hard to keep up when you're only 3 months old.
它们都很想知道是什么使摄像机发声 They all wanted to know what made the cameras tick.
明年我们会在回来 Next year we're coming back with stronger cases.
北极熊总是躲避着人类 Bears nearly always avoid people
想拍到它们是非常困难的 which made filming them next to impossible.
团队们现在很幸运 Then the team got lucky.
他们发现了一只熊妈妈和两只七个月大的幼崽 They found a mom with two cubs, about 7 months old.
整整五天 它从未离开过他们的船 For five days, she never left their boat.
因为太阳在夏天永远不会落下 Because the sun never sets in the summer
任何时候都是睡觉时间 bedtime is anytime.
没过多久 我们看到这只母熊面临着一项艰巨的任务 Before long, we saw what a tough job this mother faces
在公熊周围保护着她的熊宝宝 protecting her babies from male polar bears.
饥饿的公熊更喜欢海豹肉 Hungry males prefer seals
但在必要时 它们会一直追随着毫无防备的幼崽 but in a pinch, they have always gone after defenseless cubs.
甚至一头半吨重的公熊也会偷偷靠近 Even a half-ton male can be sneaky when he's on the prowl.
母熊似乎闻到了公熊的味道 The mother seemed to pick up the scent of a male.
但我们没有看到这只公熊 But we couldn't see him.
我们不知道她为何如此焦虑 We didn't know why she was agitated.
我们终于发现一只公熊跟随了好长一段路途 We finally spotted a male quite a ways off
离母熊和幼崽们也越来越近 zeroing in on the mother and her cubs.
现在海豹是很难捉到了 饥饿的公熊把更多的目标 Now that seals are so hard to catch, starving males
锁定在了熊宝宝上 might be targeting cubs more often.
在他快要接近时 公熊却跟丢了幼崽的气味 Before he got close, the male lost the scent.
但下一次 But next time
事情可能会变得不一样 things could be much different.
雄性幼崽寸步不离的跟随着妈妈 The male cub followed the mother everywhere, step-for-step.
但雌幼崽却充满好奇心 But the female was more inquisitive.
当母熊挨饿时 When mothers go hungry
它们无法喂养一只以上的幼崽 they're too lean to nurse more than one cub
但这个妈妈有足够的奶水来喂养两只 but this mother had enough milk to nurse two.
她时刻保持着警惕状态 She was always on alert.
一旦她闻到了公熊的气味 If she caught the scent of a male
她会赶紧把幼崽带到安全的地方 she'd hustle the cubs off to safety.
熊妈妈在五天的时间里 阻挡了来自公熊的四次攻击 This mother fended off four attacks in five days.
熊妈妈可以为宝宝做的一件事就是 The moms have one thing going for them:
她愿意以死来保护自己的幼崽 They're willing to die to protect their cubs.
调皮的幼崽会食欲大增 Playful cubs can really work up an appetite.
美味的海豹藏的很深 但饥饿的母熊会闻到它们的气味 Tasty seals may hide, but hungry moms can sniff them out.
当你想从这弄点吃的出来 When you want to grab a bite to eat up here
时间就是一切 timing is everything.
藏猫猫 Peek-a-boo.
小熊可以在它们的地盘做任何事情 The cubs finish everything on their plate
但新鲜海豹肉的气味会引起公熊的注意 but the scent of fresh seal meat attracts attention.
麻烦也在 Trouble always seems to
不经意间出现了 come along when you least expect it.
母熊带领着她的幼崽顺风而行 The mother leads her cubs away, downwind.
但公熊再一次嗅到了母熊一家的气味 But the male picks up the family's scent again.
我们眼睁睁的看着公熊悄然靠近 We watch helplessly as the male sneaks up.
母熊察觉到了危险 但从何而来? The mother senses danger, but from where?
一只公熊的重量是母熊的两倍 The male outweighs the mother two-to-one
但这并没有拖慢公熊的步伐 but all that weight doesn't slow him down one bit.
一旦强大的公熊锁定了目标 他绝不会放弃 Once the huge male locks in on his target, he never lets up.
公熊不断的追逐着母熊一家 The male keeps gaining on the family.
母熊突然转过身来面对着公熊 Then the mother turns to face him
抵挡住公熊一段时间 足以让受惊的小熊逃走 slowing him down just long enough for her frightened cubs to escape.
在关键时刻 熊妈妈发出了一个明确的警告 At the moment of truth, the mother sent a very clear message:
"你可以抓走我的熊宝宝 "You can get to my cubs if you want
但首先你必须要杀了我" but you'll have to kill me first."
这个勇敢的妈妈 为了保护她的幼崽可以做任何事情 This brave mother was willing to do anything to protect her cubs.
但她无力夺取这片它们赖以生存的栖息之地 But she's powerless to save the habitat they need to survive.
像如此雄伟壮观的自然景象 There are few truly wild places left
已经非常少了 and none so majestic as this.
但几千年以来 北极变暖的速度越来越快 But the Arctic is warming faster than it has for thousands of years
耀眼的冰川也逐渐消失 and losing its dazzling crown of ice.
北极动物依靠冰生存 Arctic animals need ice to survive.
它们生活在一个微妙的平衡自然界中 They live in a delicate balance with the natural world
妈妈是最重要的 mothers most of all.
它们怎么可能生活在一个无冰的世界? How could they live in a world without ice?
这里的妈妈无微不至的养育着它们的下一代 The mothers here nurture their young so lovingly.
也许它们会激励我们 Perhaps they can inspire us
以同样的关爱来保护它们的家园 to protect their home with that same care.
也许我们可以帮助保持北极的白色光芒 Perhaps we can help keep the Arctic white.
北极是地球上最难生存的地方之一 The Arctic is one of the hardest places on Earth to survive
但对北极熊来说 这是它们的天堂 but to a polar bear, it's paradise.
母熊与茁壮成长的幼崽快乐的生存着 Cubs play and resilient mothers thrive.
这里是它们唯一的家园 It's the only home they'll ever have.
