地球脉动 III
字幕翻译：村儿南
这里是通往 This is the entrance
最伟大自然奇观之一的入口 to one of the greatest of natural wonders.
越南韩松洞 Hang Son Doong, in Vietnam.
这里被认为是地球上最大的洞穴 It's thought to be the largest cave on Earth.
深达200米 Here, 200 metres underground,
一年中只有几周时间 for just a few weeks a year,
阳光能透过洞顶的缝隙 照射入内 sunbeams cast light through a hole in the cave's roof.
这点阳光刚好 There is just enough light
能满足植物的生长 to enable plants to grow.
随着继续深入 But travel deeper,
黑暗再次笼罩 and darkness returns.
这里的极端环境下 And you reach the limit
生命如履薄冰 of where life can exist.
第六集 极端环境
人类通常难以涉足 These most extreme places on our planet
这些地球上最极端的环境 are often hard for us to reach.
事实上 这个洞穴是最近才被发现的 Indeed, this cave was only recently discovered.
其中蕴藏着许多惊喜 And it contains many surprises.
洞穴珍珠 Cave pearls.
曾经微小的沙粒 Once tiny sand grains,
如今足有网球大小 now spheres the size of tennis balls.
巨大的石笋 And giant stalagmites...
数百年来 ..formed over centuries
由几十亿滴水日积月累而成 by billions of individual drops of water.
地下河在石灰岩中 Underground rivers have carved
开辟了这条巨大的水道 this great passage through the limestone.
长度超过8公里 Over five miles long
宽度足以容纳 and wide enough in places
一架大型喷气式飞机 to accommodate a jumbo jet.
而就在这里 And it is here,
洞穴的最深处 in the cave's furthest chamber,
孕育着生命 that life can be found.
半透明洞穴鱼 Translucent cave fish...
洞穴虾 ..and shrimps.
几千年来与世隔绝 Isolated for millennia,
仅以头顶丛林里的营养物质为生 feeding on little more than the nutrients from the jungle above.
洞穴鱼没有视觉 The fish are completely blind
只能依靠触觉辨认方向 and find their way about by touch alone.
在这些地下世界中 These underground worlds are at the very limit
生命如履薄冰 of where life can exist.
而在地面以上 But above ground,
地球上最极端的环境 our planet's most extreme conditions
非两极莫属 are found at the poles.
在北极 Here in the north,
冬天的气温可以降至零下50度 winter temperatures can drop to -50 degrees Celsius.
一年中的四个月里 For four months of the year,
几乎见不到一缕阳光 there is barely a glimmer of sunlight.
但在这里 But here, too,
生命同样有其生存之道 life finds a way to survive.
一群北极狼 A pack of Arctic wolves.
浓密的皮毛提供的保护 Their dense fur has protected them
帮助它们熬过了数月的严寒 through months of bitter cold.
但如今阳光再次洒落大地 But now the sun is returning.
埃尔斯米尔岛 This is Ellesmere Island.
短暂的夏季 使狼群得以重新积攒力量 The short summer gives the wolves a chance to rebuild their strength.
但在北极这片极端的环境 But here in the Arctic...
生命举步维艰 ..life is never easy.
狼群的首领是一只经验丰富的雌性北极狼 This pack is led by an experienced female.
如果雌狼无法带领狼群找到食物 If she can't lead them to food,
它们将很难撑过即将到来的寒冬 the coming winter could be their last.
猎物分散在如此广阔的区域 Prey is spread over such a vast area
狼群必须不断移动 that they must be constantly on the move...
以寻找猎物 ..in search of it.
但寻找猎物 仅仅是狩猎的第一步 But finding prey is only the beginning.
麝牛 Musk oxen.
体型是北极狼的五倍 They are five times the size of a wolf.
北极狼与麝牛之间的明争暗斗由来已久 The conflict between wolf and oxen is an ancient one,
可追溯至冰河时代 and has been waged since the Ice Age.
互相对彼此的战术都熟稔于心 Each side knows the other's tactics.
北极狼试图孤立 The wolves try to isolate
体弱幼小的麝牛 the weak or the young.
一只小牛跌跌撞撞 A calf stumbles...
狼群首领立即靠近过来 ..and the pack leader immediately closes in.
但麝牛群重整旗鼓 But the herd regroups,
牛角蓄势待发 horns at the ready.
陷入僵局 Stalemate.
但只是短暂的僵局 But it can only be brief.
麝牛群冲向高地 This time, the herd race to higher ground.
当麝牛群抵达山脊顶部时 As they reach the top of the ridge,
雄性麝牛转身面向敌人以自卫 the males turn to defend themselves.
再次 Stalemate...
陷入僵局 ..again.
狩猎每失败一次 Every unsuccessful hunt
狼群便虚弱一分 leaves the pack weakened.
唾手可得的午餐 This could be an easier meal.
但有些不对劲 But something is not right.
这头麝牛死于疾病 This musk ox has died from a disease.
随着北极地区气候变暖 Outbreaks like this are becoming increasingly common
类似的疫情变得越来越普遍 as the climate warms across the Arctic.
尽管饥肠辘辘 Despite their hunger,
狼群还是放弃了这具尸体 the pack don't eat this carcass.
新的麝牛群 Another herd.
新的机会 Another chance for the pack.
这一次 北极狼驱散麝牛群 This time, the wolves manage to split the herd.
成功率得以提高 That may improve their chances.
首领雌狼确保麝牛 The lead female makes sure that the oxen
无法逃往山脊 do not reach the ridge again.
随着保护的减少 小牛岌岌可危 With one less defender, the calf is more vulnerable.
雪中送炭 A much-needed meal.
北极狼群必须充分利用 The wolves must continue to make the most
夏季的最后几周 of the remaining weeks of summer...
从而在这片 ..so when winter returns
地球上最恶劣的生存环境中 ..they're ready to endure
储备能量 some of the harshest conditions
迎接即将到来的严冬 that exist on planet Earth.
如此不宜居的极端环境 Such inhospitable extremes
并非只存在于两极 are not only found at the poles.
随着海拔上升 As altitude increases...
气温大幅下降 ..temperatures fall.
在这里 动物同样必须充分利用季节变化 Here, too, animals must make the most of the seasonal change.
尤其是处于繁殖季节时 Particularly if you're ready to mate.
法国阿尔卑斯山 A male common frog
一只雄性林蛙 in the French Alps.
它整个冬天都在冰下冬眠 He has spent all winter hibernating under the ice.
但现在是时候清醒过来了 But now it's time to wake up.
林蛙是变温动物 需要晒太阳来暖和起来 Being cold-blooded, he needs the sun to warm his body.
但几小时后一旦太阳落山 But once it sets in a few hours' time,
林蛙便会冻死 he could freeze to death.
因此 寻找伴侣迫在眉睫 So finding a mate is urgent.
天气不错 The weather is good.
雄林蛙动身了 And he starts to sledge.
但竞争对手也没闲着 But this is not a one-frog race.
数十只林蛙涌向水塘 Dozens are rushing to the breeding pool.
斜坡上爬满了林蛙 This many frogs out on the slopes...
有眼睛正盯着这里 ..doesn't go unnoticed.
千万不能滑倒 You can't afford any slips.
一切都很顺利 It was all going so well.
成功抵达 Made it.
但所有雌林蛙 都已名花有主 But all the females have already got partners.
只有一个办法了 There's only one thing for it.
强取豪夺 Wrestling.
功亏一篑 Not this time.
又一只姗姗来迟的林蛙 Another latecomer.
一只雌林蛙 A female.
真命天女会是它吗 Could she be the one?
来得早不如来得巧 Sometimes being late can pay off.
煞费苦心的雄林蛙 不会让这个机会 After all his efforts, the male is not going to let this chance
再次从指间溜走 slip through his fingers.
这里是非洲北部阿特拉斯山脉的雪松林 This is the cedar forest of the Atlas Mountains, in North Africa.
这群地中海猕猴 享受了丰收的夏季 These Barbary macaques enjoyed a summer of plenty,
但好景不常 but now they're paying the price.
这里的冬季刺骨严寒 Winter here can be brutal.
某些年 半数以上的猕猴死在了冬季 In some years, over half the group perish.
在这样一个社会 But in this macaque society,
猕猴的社交能力越强 the more social the monkey,
生存几率便越大 the more likely it is to survive.
抱团取暖效果显著 Keeping warm by huddling can make all the difference.
但也不能一直抱在一起 But they can't huddle all day.
它们为了觅食 不得不从温暖中抽身 They must, eventually, break apart to feed.
猕猴四散分开 寻找食物 They spread out, searching for food.
但到了晚上 猕猴群便会回到雪松树上挤成一团 But each night, the group return to huddle in the cedar trees.
谁也不想被落下 No-one wants to be left out.
尤其是猕猴幼崽 Especially the infants.
不知怎的 这只猕猴幼崽跟大部队分散了 This baby, somehow, has got separated.
它必须回到温暖的怀抱中 以维系生命 He must get back to the life-saving warmth of the huddle,
而且必须尽快 and soon.
然而有一个问题 But there is an obstacle.
一只脾气暴躁的雄猕猴对猕猴幼崽相当冷淡 A grumpy male is giving the baby a rather cold shoulder.
换一种更隐蔽的方式 Maybe a more subtle approach.
雄猕猴决定离开 The male decides to leave.
终于 At last...
得到了热情的欢迎 ..an enthusiastic reception.
雄弥猴则运气不佳 The male has had less luck.
将是漫漫长夜等着它 It could be a long night.
抱团似乎是一种表达情感的简单方式 Huddling might seem a simple expression of affection,
但对于这些地中海猕猴来说 这对于生存至关重要 but among these macaques it's essential for survival.
而这样的行为并非绝无仅有 And not just here.
8000公里外的墨西哥树林中 5,000 miles away, in the forests of Mexico,
数百万只黑脉金斑蝶 monarch butterflies, in millions,
也为了生存挤作一团 also huddle for survival.
它们集体飞越北美大陆 All of them have travelled across North America
躲避冬季的严寒 to escape the winter that is coming there.
这片海拔3000米的森林 This forest, at an altitude of 3,000 metres,
似乎并不能提供舒适的环境 might seem to offer little comfort...
因为这里的气温可降至零度以下 ..for temperatures here can drop below freezing,
如此低温能置蝴蝶于死地 and that could kill the butterflies.
然而事实上 树冠保有 But in fact, a thin layer of warm air
薄薄的一层暖空气保护着蝴蝶 trapped by the tree canopy protects them,
只要森林不受干扰 and will do so throughout the winter...
就能一整个冬天为蝴蝶提供保护 ..provided that the forest remains undisturbed.
然而 不可预测的极端天气 Unpredictable extremes of weather, however,
会破坏这一微妙平衡 can disrupt this delicate balance.
强风吹进森林深处 降低气温 Strong winds can push deep into the forest, chilling the air.
数十万只蝴蝶 Hundreds of thousands of butterflies
受强风席卷 掉下树枝 may be blown from the branches.
某些年 75%冬眠中的黑脉金斑蝶死于风暴 In some years, storms kill 75% of hibernating monarchs.
这只蝴蝶得以幸存 This one has survived...
但也掉落在地 ..but on the ground.
夜间的霜冻足以致命 And night-time frosts are fatal.
因此它不能留在这里 It can't stay here and live.
尽管天气过冷 无法飞翔 It is too cold to fly,
但它必须找个办法 回到树枝上 but it must get back into the tree branches somehow.
因此它开始爬树 So it starts to climb.
困难程度相当于 人类徒手爬上摩天大楼 It's the equivalent of a human climbing up a skyscraper.
终于安全了 Safety, at last.
春天来临时 As spring returns,
黑脉金斑蝶从漫长的沉睡中苏醒 the monarchs wake from their long slumber.
地球上最伟大的自然奇观之一 就此拉开帷幕 And now starts one of the Earth's greatest natural spectacles.
然而 这种集体复苏的生活习性正面临威胁 But this mass awakening is under threat.
气候变化引发越来越多极端天气 The changing climate is creating more extreme weather,
风暴也越来越频繁 and storms are becoming more frequent.
但就目前而言 这一自然奇迹仍在继续 But, for now, this miracle of nature continues.
火灾 Fire.
不可预测且破坏力十足 Unpredictable and destructive.
这里是南非的弗因博斯 This is South Africa's fynbos.
是地球上最植物多样化的栖息地之一 Botanically one of the most diverse habitats on Earth...
生长着8000多种不同的植物 ..with over 8,000 different plant species.
然而 每二十年 Yet, every two decades,
火灾将植被焚烧殆尽 fire reduces the vegetation to ashes.
这一切看似是毁灭性的 This may seem catastrophic.
但就在几天后 植物再次焕发生机 But just days later, plants burst into life...
重塑这片土地 ..and transform the landscape.
种子与鳞茎 一直在蛰伏等待这个机会 Seeds and bulbs have been waiting for this event.
9000万年的进化 使部分植物 90 million years of evolution alongside fire
得以适应 这片常有火灾的大地 has made some plants so closely adapted
以至于种子只有在浓烟下 才会发芽 that they can't germinate without the presence of smoke.
值得注意的是 地球上约50%的陆地栖息地 Remarkably, around 50% of planet Earth's terrestrial habitats
依靠火来维持群落健康 depend on fire to remain healthy.
在澳大利亚北部 这些稀树草原需要季节性火灾 In Northern Australia, these savannahs need seasonal fires
才能防止森林的扩大 保持草原的开阔 to keep them open and prevent the spread of the nearby forest.
而对于这一多彩的居民来说 And they are a vital habitat
稀树草原是重要的栖息地 for this colourful resident.
稀有的金肩鹦鹉 The rare golden-shouldered parrot.
这只雄性鹦鹉 以及它终身的伴侣 He and his lifelong partner..
依赖于草原提供食物 rely on grassland for both food...
以及筑巢地 ..and a nest site.
金肩鹦鹉照例 将卵产在白蚁丘的洞中 As usual, they've laid their eggs in a hole in a termite mound.
如今育有四只雏鸟 And now there are four chicks.
厚厚的泥墙 不仅能保护雏鸟免受捕食者伤害 The thick mud walls don't only protect chicks from predators,
还能遮挡烈日 but insulate them from the heat of the scorching sun.
雏鸟羽翼渐丰 With fledging just days away,
金肩鹦鹉父母加班加点 the parents are working overtime.
每天搜集成千上万枚种子 They collect thousands of seeds every day.
然而有一个问题 But they have a problem.
火灾季节变得越来越不规律 The fire season is becoming more irregular.
如果雏鸟还不会飞 If they are not ready to fly,
它们将无路可逃 chicks have no escape.
但选择在白蚁丘中筑巢 有着意想不到的好处 But choosing to nest in a termite mound has a surprise benefit.
房子可以防火 Their home is fireproof.
混泥土般的墙壁 能保护雏鸟不受火焰的伤害 Concrete-like walls keep chicks safe from the flames outside.
在烧焦的土地上 The seeds of fire grass are now easier for the parrots
金肩鹦鹉更容易找到裂稃草的种子 to find on the blackened earth...
这是它们最爱的食物 ..and they are the parrots' favourite food.
因此 对于金肩鹦鹉一家来说 So, for both adults and their fledgling chicks...
熊熊烈火对于生存至关重要 ..fires are essential for survival.
但如今 它们的草原家园正在缩小 But their grassland home is shrinking,
只有约1000只可爱的金肩鹦鹉幸存 and only about 1,000 of these lovely parrots still survive.
通过人类对于火情的积极管理 It's through the active management of fire by humans
金肩鹦鹉的世界才得以存续 that their world now exists at all.
人类活动 深刻影响着地球上的栖息地 Humans are affecting habitats across planet Earth.
这对于野生动物来说 For wildlife, all too often,
后果往往是灾难性的 the consequences have been disastrous.
大象是耐受力最强的动物之一 Elephants are among the most tolerant of animals.
它们十分长寿 They are very long-lived,
代代相传的知识 and knowledge passed between generations enables them
使大象在极端环境下 to find food and little-used sources of water in times
能够找到食物和隐蔽的水源 of great environmental stress.
但即使如此 But even among elephants,
大象的生存策略 如今也面临挫折 survival strategies are now beginning to fail.
在肯尼亚的安博塞利 多年的极端天气 In Amboseli, Kenya, years of extreme weather,
加上家畜的过度放牧 combined with overgrazing by domestic cattle,
使这片草原失去了原有的绿色 are turning these grasslands to dust.
年逾40岁的首领雌象 This matriarch is over 40 years old...
曾经历过非洲东部 ..and she's already survived
最严重的干旱 some of East Africa's worst droughts.
但今年 食物极度短缺 But this year, food is in extremely short supply...
很难满足整个家族的需要 ..and her family are struggling to find enough.
雌象最小的孩子营养不良 身体虚弱 Her youngest son is malnourished and weak...
落在家族的最后 ..and is lagging behind his mother and brother.
雌象带领家族 来到一片熟悉的金合欢树林 She leads them to a pocket of acacia forest that she knows well.
然而折断的树枝与倒下的树木 But broken branches and fallen trees
表明其他大象已经来过此处 show that other elephants have already been here.
几乎没剩下什么食物 There is very little left worth eating.
饥肠辘辘的雌象 无法分泌足够的乳汁 Without food, his mother cannot produce enough milk.
雌象别无选择 She has no choice...
只能留下虚弱的小象 ..but to leave her weakening calf...
前往别处寻找食物 ..and try to find food elsewhere.
因此 小象只能眼睁睁看着母亲与兄长 So, she and her elder son head off...
离自己而去 ..without him.
小象只能寄希望于母亲会回来 He can only hope for their return.
然而时间已经来不及了 But for him, time has run out.
面对如此惨剧 There is nothing his mother, or anybody,
母亲也无力回天 could have done to save him.
大儿子的生命还在继续 With her elder son still alive,
大象家族希望尚存 there is hope for her family.
前提是它们能迅速适应 如此极端的环境 But only if they can adapt quickly.
一些大象家族 展现出了非凡的适应力 Some families are proving to be resilient.
它们长途跋涉 离开安博塞利 They're travelling long distances, away from Amboseli...
寻找新的食物和水源 ..and finding new sources of food and water.
尽管在如此干旱的环境下 And despite the drought...
新生命的诞生从未止步 ..calves are being born.
但考虑到环境变化的速度 But given the pace of change
以及象群面临的严峻挑战 and the challenges they face...
究竟有多少非洲大象 能够适应如此极端环境 ..how many of Africa's elephants will be able to adapt?
而适应的速度又能来得及吗 And can they do so fast enough?
戈壁沙漠 The Gobi Desert.
沙与雪覆盖的大地 A land of sand and snow.
至少一百万年来 这里一直是 For at least a million years, this has been
地球上最极端的栖息地之一 one of the most extreme habitats on Earth.
尽管如此 沙子上的足印 Yet, footprints in the sand
表明这里仍孕育有生命 reveal that there is life here.
雪豹 A snow leopard.
极其罕见 Seldom seen...
尤其是在如此炎热干旱的环境下 ..especially in such hot, arid conditions.
雪豹生存于海拔2000米以上 They live up to 2,000 metres above sea level,
掌控广阔的领土 and patrol vast territories.
雪豹极少聚居 They are rarely seen together.
一只雪豹母亲 A mother...
养育着幼崽 ..with cubs.
这是首次拍摄到 Filmed here for the first time
雪豹如此亲密的画面 in such intimate detail.
这使得我们得以窥见雪豹的家庭生活 And they give us a glimpse of their family life...
凡此种种 ..such as it is.
雪豹幼崽留在母亲身边的时间 Snow leopard cubs stay with their mothers
几乎比任何大型猫科动物都长 longer than those of almost any other big cat.
母子相互陪伴长达两年以上 They remain together for over two years...
学习在极端环境下的生存之道 ..as they learn how to master the extremes.
使它们得以在地球上最热 最冷 Which they do so well that they are able to thrive
海拔最高的种种环境下 in some of the hottest, coldest...
茁壮成长 ..and highest places on Earth.
数百万年的进化 使有些动物 Some animals, over millions of years,
能够在极端恶劣的条件下生存 have evolved ways of surviving extremely hostile conditions.
但随着环境条件越来越极端 But as the extremes become more extreme...
进化渐渐赶不上变化的速度 ..evolution is being outpaced.
这些非同寻常的地方 These extraordinary places are still inhabited
仍然居住着一些地球上 by some of Earth's most resilient
最具适应力的物种 and adaptable species.
但在这个瞬息万变的世界 But in our rapidly changing world...
如此千姿百态的地球 也许终将成为回不去的过往 ..this is planet Earth as you may never see it again.
幕后花絮
地球上最极端的环境 The most extreme parts of our planet
有时位于意想不到的地方 are not always found where you might expect.
何康先生隐居于越南的森林深处 Hidden deep in the forests of Vietnam, a local man,
有一个惊人的发现 Mr Ho Khanh, made an extraordinary discovery.
一个下雨的下午 One rainy afrernoon
我躲在一个洞穴里 I sheltered in a cave opening.
我看见洞穴里升起薄雾 I saw mist rising from the inside.
跟别的洞穴不一样 It was different from the other caves.
尽管当时并不知情 He didn't know it at the time,
但他偶然发现了世界上最大的洞穴 but he had stumbled upon arguably the largest cave in the world.
我感到十分荣幸与自豪 to show the world such a magnificent cave
向世界展示如此一个宏伟的洞穴 It's a source of pride and honour
从何康的发现中得到启发 Inspired by Mr Ho Khanh's discovery,
「地球脉动」摄制组动身前往韩松洞进行拍摄 the Planet Earth team set out to film Hang Son Doong.
但首先得能够抵达洞穴 But first, they have to get there.
我们离开了河谷 We've left the river valley,
向上走到入口处 and we're walking uphill now to the entrance.
森林特别茂密 It's just thick, thick forest.
经过两天艰苦的跋涉 After trekking for two gruelling days,
摄制组终于抵达了目的地 the team finally arrive.
下面是韩松洞入口 Down here is the entrance to Hang Son Doong,
巨大丛林中的一个小小入口 this tiny opening in this massive jungle.
能发现这个地方实在是了不起 It's amazing that anyone ever found this place.
我们将在里面逗留18天 We're about to go in for the next 18 days,
灯现在开始常亮 and it's lights on from here on out.
当地专家带领摄制组穿过黑暗 Local experts guide the team through the darkness.
-我可以走吗 -可以了 OK, I can go? Yes, yes.
没问题 I'm good. I'm OK.
洞壁太滑了 It's just really slippery.
一套复杂的绳索系统 帮助他们向下垂降90米 A complex system of ropes leads them down a 90-metre descent.
-注意别撞到 -好的 Watch your head! OK.
谢谢 Thanks.
在岩石上攀爬了四个小时后 After four hours clambering over rocks...
他们终于抵达了营地 ...they finally reach what will be their camp.
迎来新的一天 The team wake to a new day -
但四下黑漆漆一片 but in darkness.
睡得怎么样 卢克 How did you sleep, Luke?
还是很累 Quite tired.
这些都是我身后的帐篷 These are all of the tents behind me.
可以看到这些帐篷 You can see they are pretty...
都挺舒适 ..pretty snug.
这是我们每天吃早餐的地方 This is where we have our breakfast every day,
厨师手艺精湛 made by some amazing cooks.
这里是充电站 This is our charging station.
相机的电池 灯的电池 Batteries for camera equipment, batteries for our lights,
头戴式电筒的电池 至关重要 our head torches, which are so important.
这里是供水站 This is our water station.
所有东西都是别人千辛万苦搬进来的 Everything that we have got has been brought in by someone,
所以不能洗澡洗衣服 so you can't shower or wash.
除了水以外 And it's not just water.
还要将成吨的设备搬进洞内 Tonnes of equipment has had to be carried into the cave,
一步一个脚印 every inch of the way.
现在在地底深处 Now deep underground, the powerful lights
光照显示出这个洞穴究竟有多大 reveal just how vast this cavern is.
太不可思议了 That is amazing.
看哪 这里简直 Look at that. It's...
简直太大了 It's huge!
随着一盏盏灯被点亮 As you turn on each of the lights,
洞穴深处的黑暗被驱散 another part of this enormous chamber is revealed.
太神奇了 It's magic. Absolutely magic.
为了展现真实的尺度 To try and capture the true scale,
摄制组尝试了一种新的拍摄技术 the team attempt a filming technique never tried before.
我们正尝试让无人机起舞 We're trying to do a little bit of a dance with the drones,
一台无人机略低于另一台 whereby we have one drone sort of slightly below the other,
一台负责照明 一台负责拍摄 one filming the other one lighting a feature in the cave.
空间特别狭小 It's a really tight space.
伸手不见五指 You can't see anything.
情况不能再糟了 What could go wrong?
慢一点 OK, slow down a bit.
每个人都有些紧张 It's making everyone a little nervous.
不能再高了 卢克 Yeah, don't go up any higher, Luke.
这个高度不错 OK, that's a nice height.
一台无人机照明 一台拍摄 With one drone lighting and one drone filming...
为我们展现了 一些世界上最大的奇特石笋 ..they reveal the wonder of some of the world's largest stalagmites.
随着时间流逝 摄制组适应了 As the days pass, the team settle into
地底的日常工作 the everyday routine of life underground.
这是脱离尘世的写照 This is the epitome of being off-grid.
我们叫它跷跷板厕所 We call that one seesaw loo
因为它下面有颗石头 because it's kind of on a rock,
每次坐在上面都会后倾 and every time you sit on it and lean back,
不禁让人担心会弄得一团糟 you're scared that there's going to be a disaster.
最异样的是我们跟外界 The strangest thing is having no connection
没有任何联系 to the outside world whatsoever.
生物钟彻底紊乱 地底下一切都不一样了 Time is warped. Nothing makes sense underground.
开灯 Lights on!
没有日光的指引 摄制组不分昼夜地工作 Without daylight to guide them, the team work round the clock
拍摄洞穴中独特的镜头 to capture the cave's most unique features.
最特别的是 Most special of all,
一年中只持续几周的活动 an event which happens only a few weeks a year.
为了到达那里 他们必须穿过 To get there, they must navigate
巨石区和狭窄的道路 through boulder fields and tight squeezes.
在这里 约50万年前 Here, around half a million years ago,
洞顶坍塌下来 the cave roof collapsed,
开启了一扇通往外界的窗 opening a window to the outside world.
摄制组等待合适的条件 The team wait for just the right conditions.
我们坐在这几小时了 We've been sat here for hours.
最后 在右侧的墙上 And finally, just on the right-hand side of the wall,
能找到光线的踪迹 we can see the first signs of light.
经过数周的黑暗 After weeks of darkness
在200米深的地底 200 metres underground...
他们看到阳光 ..they see sunlight
照亮了洞穴 illuminate the cave floor.
整个巨大洞穴都被照亮了 The way it just lights up this massive cave...
我们本来试图用四五盏灯点亮这里 ..when we've been trying to do it with about four or five lights
结果根本行不通 and barely even lighting the smallest section.
阳光照进来的时候 When the sun comes in, it just...
我相信每个人都起鸡皮疙瘩了 I think everyone's got goose bumps.
我想这是我第一次如此感激太阳 I don't think I've ever appreciated sun so much in my life.
太难以置信了 It's incredible.
看那些背光的瀑布 Look at the backlit waterfalls.
坠落如此缓慢 They're so slow coming down.
这真是我见过最美好的事情之一 It's literally one of the best things I've ever seen.
对于摄制组来说 阳光标志着 For the crew, the sunbeam marks a profound end
洞穴作业画上句号 to their time in the cave.
我们出来了 We're outside!
绿色的丛林 明媚的阳光 It's so green, it's so bright.
回到地面上 满满的归属感 Being back above ground feels like where we belong.
地球表面之下究竟还隐藏着 It's a wonder to imagine what other extremes
什么样的极端环境 实在是不可思议 still lie beneath the surface of planet Earth.
下一集 Next time...
人类世界 ..the human world...
在这里 动物必须探索新的方式 ..where animals must find new ways to survive...
与我们共存 ..amongst us.
