这是赞比西河的故事 This is the story of the Zambezi...
非洲最野性的河流 ..Africa's wildest river.
发源于赞比亚的西北部 From its source in the northwest of Zambia,
赞比西河旅行超过1500英里， the Zambezi travels over one and a half thousand miles,
经过六个国家，行程最终会 through six countries, on its course
到达印度洋 to the Indian Ocean.
就像许多大河一样，它的起点只是小溪流 Like many great rivers, its beginnings are humble.
命运没有定数 And its destiny by no means certain.
沿着诞生它的森林奔涌而出 Flowing down out of the forests of its birth,
赞比西河开始它宏大的旅程 the Zambezi starts its great journey.
但是，就在河水开始流动不久，它遇到了麻烦 But just as its waters are getting going, it runs into trouble.
巴罗特斯兰 Barotseland.
赞比亚西部的一片无穷无尽的平原 An endless flat plane in the far west of Zambia.
非常平坦，赞比西河完全失去了前进的动力 So flat, the Zambezi completely loses momentum.
现在是9月，旱季的高峰 And it's September, the peak of the dry season.
在非洲太阳的炙烤下，水不断被蒸发 Its waters are evaporating under the heat of the African sun.
现在赞比西河至关重要 But it's just now that the Zambezi is vitally important.
特别是对住在这里的人来说， Especially for the people that live here,
比如养牛的农民，马卡洛·马考洛 like cattle farmer Makalo Makaulo.
九月是一年中最热的时候， September is the hottest time in the year,
一切都干涸了 where everything is dried out.
我告诉你们，我们正在受苦，因为我们依赖水 I tell you we are suffering because we depend on water.
这里是巴罗特斯兰， Here in Barotseland,
一切都依赖于水 everything depends on water.
旱季的每一天 Every day in the dry season
为了让牛活着， to keep his cows alive,
马卡洛，必须从干旱的草原上驱赶牛群 Makalo Makaulo must take them from the arid grasslands
到达赞比西的生命之水 to the Zambezi's life-giving waters.
赞比西河 Zambezi River,
对我来说，赞比西就像一个父亲 it's like a father to me.
养育孩子的父亲 The father who feeds his children.
养育巴罗特斯兰的父母是赞比西 The parent of Barotseland is Zambezi.
随着高温的加剧， But as the heat intensifies,
赞比西河正在消退 the Zambezi's waters are receding...
留下数英里干燥炎热的河床 ..leaving miles of dry, hot riverbed.
一个充满挑战的地方， A challenging place,
不管你的生活之路是什么。 whatever your walk of life.
但旱季也有特点 But there are advantages to the dry season.
对于小学生和养牛的农民来说， For schoolboys and cattle farmers alike,
生活还得在旱季继续 life goes on through the dry season.
与这里的野生动物一样 As it does for the wildlife here.
这些辽阔的平原是非洲的野生动物的家 These vast plains are home to some of the greatest concentrations
是最集中的地方 of wildlife anywhere in Africa.
现在是他们最艰难的时刻 And this is their toughest time.
不过，高温只能持续这么长时间 But the heat can only build for so long.
现在是十月，巴罗特斯兰区正在发生变化 It's now October, and a change is coming to Barotseland.
超过3万只角马正在迁徙 Over 30,000 wildebeest are on the move.
他们正前往平原南部的产犊场， They are heading for their calving grounds in the south of the plains,
并期待着下雨 in anticipation of the rains.
这是六个月干旱即将结束的迹象 A sign that six months of drought is coming to an end.
当下雨来临， When the rain is coming,
一切都会改变 everything is changing.
每年10月 In October every year
热带降雨从赤道向下推进， tropical rains push down from the equator, and spill
并倾泻到巴罗特斯兰区 over into Barotseland.
这是所有居住者一直翘首以盼的， This is what all the inhabitants have been waiting for.
所以开始下雨时，大家都欢呼雀跃， So when the rains come, our hearts are feeling very happy,
因为我们期待着美好的未来 because we are expecting good things to come.
我不知道你是怎么表达的，因为那里的一切， I don't know how you even express it, because everything there,
甚至大自然都在改变 even the nature of the land is changing.
雨水带来了彻底的变革 The rains are completely transformative.
7000多平方英里的土地绿化 A greening of the land over 7,000 square miles...
甚至可以从太空中看到 ..that can even be seen from space.
天哪，为什么这期间不能一直这样？ My God, why can't this period be like that always?
随着草原的恢复， As the grasslands are revitalized,
这里成为全球重要的湿地， they become a globally important wetland,
350种鸟类来到这里 supporting 350 species of birds.
最后， And finally,
牛羚到达产犊地 the wildebeest arrive at their calving grounds.
仅仅几个星期， Over just a couple of weeks,
所有的牛犊出生 all the herd's calves are born
正好赶上这个丰润充足的时期 to coincide with this time of plenty.
呱呱叫 CROAKING
但是降雨的影响更为显著 But the rains are having an even more dramatic effect...
在赞比西河上 ..on the Zambezi.
洪水开始泛滥 It starts to flood.
巴罗特斯兰的人民一直生活在按部就班之中 The people of Barotseland have always lived in tune
面对赞比西河每年的洪水 with the annual flooding of the Zambezi.
主要的村庄都建在高处的陆地上， Larger villages are built on high ground,
在洪水期间，都能保持干燥 so they stay dry during the flood.
但许多较小的建筑 But many smaller buildings
被设计成可以耐水一段时间 are designed to be submerged for a while.
弃置四五个月，直到水位下降后再使用。 Abandoned for four or five months until the waters subside.
水位上升带来了新的挑战 The rising waters bring new challenges.
大多数孩子在雨季不得不辍学 Most children have to stop going to school in the wet season.
但这所学校的建设考虑到了洪水因素 But this school has been built with flooding in mind.
建造在高地上， Set on a mound of high ground,
甚至还配有供学生们使用的码头 it even has docks for the pupils to tie up to.
只要他们能勇敢面对上学的挑战， So long as they can brave the school run,
基夫和同学们可以保持 Gift and his classmates can keep
在水位不断上升的同时学习 learning while the waters keep rising.
养牛户没有选择留在洪泛平原 Cattle farmers don't have the option of staying in the floodplains.
他们现在乘独木舟，让牛游泳 They now take to canoes to swim their cattle
到更高的地方去 to higher ground.
但在水下， But beneath the waters,
土地正在增肥 the land is being fertilised
赞比西河的淤泥 by the Zambezi's silt.
所以当牛再次回来的时候， So when the cattle return,
他们将拥有 they will have some of the most
周围最富营养的草地 nutritious grass around.
洪水不仅对巴罗特斯兰的居民有益 The floods are not only good for the inhabitants
of Barotseland...
整个洪泛平原的河水正在汇集 ..the waters of the entire flood plain are now gathering
进入一个生机勃勃的流程 into one rejuvenated flow.
赞比西河 The Zambezi
又开始前行 is on the move again.
从巴罗特斯兰出发， Heading out of Barotseland,
赞比西河现在转向东 the Zambezi now turns east
在接下来的300英里里，它将形成一个边境 where, for the next 300 miles, it will form the border
在赞比亚和津巴布韦两个国家之间 between Zambia and Zimbabwe.
在上游水的推动下， Boosted by the water from upstream,
赞比西河水位在上涨 the Zambezi grows.
而且，随着上涨，它为生活带来了更多的机会 And, as it grows, it brings more opportunity for life.
赞比西河开始像一条大的非洲河流 The Zambezi is starting to look like a great African river.
当流过基岩中的一系列落差时， As it flows over a series of steps in the bedrock,
它开始加快速度 it starts to gather pace.
远处，一团薄雾升腾着 And, in the distance, a cloud of mist is rising.
暗示即将发生的事情 A hint of what is to come.
就在赞比西河达到最大力量的时候 Right at the point where the Zambezi reaches its maximum power...
整条河在悬崖边形成瀑布 ..the entire river flows over a cliff.
一英里宽 Over a mile wide...
…高度超过一百米 ..falling for over a hundred metres...
每分钟5亿升水 ..500 million litres of water per minute.
这么多的水，产生了一团团水汽 So much water, it creates a plume of spray
500米高 that rises 500 metres into the sky...
名为莫西奥图尼亚瀑布， ..giving it the name of Mosi-oa-Tunya,
“雷鸣雨雾” The Smoke That Thunders.
这就是维多利亚瀑布 This is Victoria Falls.
最大的瀑布 The largest curtain of water...
世界上有名 ..on the Earth.
(维多利亚瀑布是世界著名瀑布奇观之一， 水雾形成的彩虹远隔20 公里以外都能看到。)
你可以不来这里旅游 You would think it's a place to steer well clear of.
但这里太有诱惑力了 But there is temptation here.
一群雄象已经来到河边 A group of male elephants have come down to the edge of the river.
每年的这个时候，瀑布上方的岛屿郁郁葱葱 At this time of year, the islands right above the falls are lush
有美味的植物， with tasty vegetation,
大象的天堂 an elephant's paradise.
但是接近他们是危险的 But to reach them is dangerous.
洪水泛滥的赞比西河是一股强大的力量 The Zambezi in full flood is a formidable force.
这里不是被水流冲走的地方 This is not the place to get swept away by the current.
这些岛屿的吸引力很强 But the lure of the islands is strong.
这些雄性做好了冒险的准备 These males are prepared to take the risk.
越靠近河中心， The further they go,
水流越急 the stronger the current gets.
现在更深了 And now it's getting deeper.
走步只能换成游泳 They are forced to swim.
急流立即开始将他们带向下游 Immediately, the current starts to drag them downstream.
他们想要到达一个岛 They need to reach an island
或者他们可能会被瀑布卷走 or they could get swept over the falls.
他们一个接一个地找到了立足点 One by one, they find their footing.
大象叫 ELEPHANT TRUMPETS
但对于体型较小的大象， But for smaller elephants,
危险更大 the danger is greater.
最后，他们总算都安全通过 At last, they are all safely across.
马上就开始享用他们的奖赏 And right away, they start feasting on their prize
丰富的植物 of rich vegetation.
大象一天可以吃300公斤食物 But elephants can eat 300 kilos of food in a day.
他们很快就品尝完了这里最美味的食物 So they'll soon get through all the tastiest pickings here...
又将不得不再次在赞比西河里碰运气 ..and will have to take their chances with Zambezi all over again.
维多利亚瀑布标志着下一个伟大的转变 Victoria Falls marks the next great transformation
对赞比西和而言 for the Zambezi...
整条河都被地球上的一个大裂口吞没了 ..as the entire river is swallowed up by a great chasm in the Earth.
被限定在25米宽的峡谷里， Trapped in a channel just 25 metres wide,
赞比西河现在横穿非洲的岩石中心 the Zambezi now carves down through the rocky heart of Africa...
形成的140米高的垂直墙 ..forming sheer walls of 140 metres high.
这是巴托卡峡谷 This is the Batoka Gorge.
赞比西河在这里的景色 And it's here that the Zambezi conjures up another phenomenon...
…不如维多利亚瀑布出名， ..less well-known than Victoria Falls,
但同样独特 but just as unique.
赞比西波浪 The Zambezi Wave.
冲浪特别适合那些敢于冒险的人 Surf perfection for those brave enough to try it.
你能带冲浪板来这里，真是太疯狂了 It's crazy that you can bring something like surfing here.
米奇·费波是一名职业冲浪者 Mikey February is a professional surfer.
这里，离最近的海洋600英里， He's here, 600 miles from the nearest ocean,
在赞比西的波浪上冲浪 to surf the Zambezi Wave.
一生中的一次，只有少数人真正做到， It's once in a lifetime, and only a few people have actually done it,
我认为这是，你知道，是最特别的部分之一 and I think that's, you know, one of the most special parts
真的到达这里 of actually coming here.
米奇在今年的关键时点来到赞比西 Mikey has come to the Zambezi at a key point in the year.
随着旱季的到来，经过三、四个月后， As the dry season returns, over a period of three or four months,
河流又变了 the river changes again.
维多利亚瀑布开始停歇 Victoria Falls starts to switch off.
每年，赞比西河都会经历这些戏剧性的周期 Every year, the Zambezi goes through these dramatic cycles...
当河流干涸时，水流会减少50倍 ..with 50 times less water flowing over the falls when it's dry.
因为峡谷的水位开始下降 But it's as the water levels in the gorge start dropping
这种条件才适合冲浪 that conditions become just right for surfing.
当水位降到足够低时， When the water gets low enough,
水流冲击岩石 it starts to interact with a rocky
从河床上的底岩涌起 shelf on the riverbed...
就形成了赞比西波浪 ..and forms the Zambezi Wave.
并在同一位置出现波浪， A wave that stays in exactly the same place,
又不断地变化 and breaks continuously.
时间只持续十天 But only lasts for ten days.
即使像米奇这样的职业选手， Even for a pro like Mikey,
赞比西波浪 the Zambezi Wave is
也不能被轻视 not to be taken lightly.
有石块，你知道， You have rocks, you have, you know,
急流汹涌，水流湍急 hectic rapids and the water's moving
以一种与海洋截然不同的方式 in such a different way to the ocean.
相当惧怕 The fear factor is quite high.
因为波浪是由水面下的岩石形成的， Because the wave is formed by a slab of rock just beneath the surface,
冲浪很危险 surfing it is dangerous.
还有急流 And then there are the rapids.
米奇需要尽快离开翻泡沫的水， Mikey needs to get out of the white water as fast as he can,
在他被冲到下游之前 before he gets swept downstream.
他划着桨去河岸上的落脚点 He paddles for the pickup point on the riverbank.
但水流太急了 But the current is too strong.
在水中的经验告诉他 This is where his experience in the water comes in.
保持冷静 He keeps calm.
皮划艇安全员赶过来帮忙 And the safety kayaker is immediately on hand to help
引导他摆脱困境 guide him out of trouble.
米奇渴望再试一次 Mikey is keen to try again.
赞比西波浪很像捕捉海浪 The Zambezi Wave is pretty much like catching an ocean wave
但相反，因为海洋在推动你前进， but in reverse, because the ocean is pushing you forward
这个河流却显然是反方向推动 and the river is obviously going the opposite way.
这只是一种迥然不同的体验 It's just a completely different experience.
你一旦有机会接触到它， Once you get it the first time,
你就会有一个应对之法 then you actually kind of get a gauge
该怎么做 of what you should be doing.
当你摔倒的时候，你会知道下次怎么做 And you kind of know exactly what to expect when you fall.
我在这波浪里冲浪时，确实很害怕 I did get scared surfing this wave.
这就像冲浪和生存之间的平衡， It's like a balance of, like, surfing, survival mode,
冲浪，生存模式之类的 surfing, survival mode kind of thing.
我想你在河里波浪上待的时间越多， I think the more time you spend in the river and on the wave,
你会学到东西越多 you learn new things about it.
移动的方式和注意到它的细微之处 The way it moves and noticing its, you know, little subtleties.
它也很美，你知道， It's also so beautiful, you know,
显然你可以在这波浪中冲浪， obviously you get to surf this wave,
但你也可以欣赏赞比西河和其他一切 but you also get to appreciate the Zambezi and everything
由它提供的东西。 that it has to offer.
从峡谷出发，赞比西河继续前行 From the gorge, the Zambezi journeys on.
蜿蜒穿过边境裂开的大地 Winding its way through the fractured land along the border
位于赞比亚和津巴布韦之间 between Zambia and Zimbabwe.
它将再次改变形貌 But it's about to shapeshift once more.
这一次，是一种完全不同的影响力 This time, at the hands of an entirely different force.
卡里巴大坝 Kariba Dam.
建于20世纪50年代， Built in the 1950s,
完全挡住了赞比西河， it completely blocks the Zambezi,
通过涡轮机发电 and forces it to flow through its turbines to make electricity.
建造大坝花了五年时间，河水就被拦住 It took just five years for the river, held back
在大坝后面， behind the dam,
水位上升了100米 to rise 100 metres.
形成一个巨大的卡里巴湖 Swelling up to form the vast Lake Kariba.
25英里宽 25 miles wide.
140英里长 140 miles long.
容纳44立方英里的水 44 cubic miles of water.
注入如此之多的水，引发了20多次大地震 So much water that it caused over 20 large earthquakes as it settled
在下面的陆地架构上 down on the land beneath.
卡里巴湖是世界上最大的人工湖 By volume, Lake Kariba is the largest manmade lake
这个星球上 on the planet.
它也成为了野生动物的天堂 But it has also become a haven for wildlife.
沿着湖岸线，是丰美的草原 Along the lake's shoreline, rich grasslands have grown up.
一片淹死的树林 And in the forests of drowned trees
由上涨的水造成 formed by the rising waters
恰好成为一个独特的栖息地 is a unique habitat.
非常适合赞比西最具标志性的鸟类 Perfect for the Zambezi's most iconic bird.
非洲鱼鹰 The African fish eagle.
这里大约有500对，正在繁殖之中 There are around 500 breeding pairs here.
每一对都是终身伴侣 Each pair mates for life...
树木扭曲的形状有一个小平台 ..the contorted shapes of the trees providing a platform
正好筑巢 for their nests...
…同时水面下有鳄鱼保护 ..protected by the crocodile-infested waters below.
树木也提供了绝佳的观哨点 The trees also provide the perfect vantage point
可以搜寻湖中的猎物 to survey the lake for prey.
拥有两米长的翅膀，在浅水里捕鱼 On two-metre wings, they hunt for fish in the shallows.
这地方适合鱼鹰， This place is so good for fish eagles,
它成了他们的据点 it has become their stronghold...
萦绕不去的叫声，成了卡里巴湖的特有声音 ..their haunting call, the sound of Lake Kariba.
赞比西河目前还有一半的旅程 The Zambezi is now at the halfway point on its journey
到达印度洋 to the Indian Ocean.
当河水冲出大坝， As its waters break free of the great dam,
河水继续前行 the river flows on.
现在它进入了一个失落的世界， And now it enters a lost world,
扩展到50英里宽的流域 spreading out into a valley 50 miles wide...
滋养了一片广阔的荒野 ..nurturing a vast wilderness...
非洲最丰富的野生动物栖息地 ..some of the richest wildlife habitat in Africa.
它也成为世界著名的 It has also become world famous as one of THE places to come
来观察野生动物的地方 and watch wildlife.
赞比西河及其支流的这一部分星罗棋布 This part of the Zambezi and its tributaries is dotted
分布着观兽小屋 with safari lodges...
人们来这里观赏赞比西的标志性动物 ..places where people come to meet the Zambezi's iconic animals.
但谁看谁？ But who's watching who?
这个观兽小屋已经经营了很多年， This safari lodge has operated for many years,
野生动物现在已经习惯了人类的出现 and the wild animals are now used to people.
大堂外还有一个主要景点 And there's one main attraction just beyond the lobby.
野生芒果树 A wild mango tree.
它果实成熟的时间很短， Its fruit is ripe for just a short time,
正好在旱季结束的时候 right at the end of the dry season.
食物短缺，令人垂涎三尺 A mouth-watering treat when food is scarce.
不仅是狒狒喜欢吃芒果 But it's not just baboons that have a thing for mangoes.
有更大的客人也要到这间小屋 There are larger guests about to check into this lodge.
大象从附近的河流来到这棵芒果树前 Elephants have been coming to this mango tree
代代相传 from the river nearby for generations,
沿着很久以前，就存在的古老道路 following ancient pathways that existed long before
屋子是后建的 the lodge was built.
特别是大象家庭了解到：房屋及其居民 One family in particular has learned that the lodge and its inhabitants
没有威胁 poses no threat.
为什么要绕着走呢？ Why go around?
还是直接穿过接待处吧 When you can walk right through reception.
这些完全是野生大象 These are completely wild elephants.
多年来，他们已经理解 But over the years, they have developed an understanding
这里的工作人员 with the staff here.
大象世代相传的信任 A trust passed down through elephant generations.
我们肯定发展了这种关系， We've definitely developed that relationship
我们看到，多年来年轻象几乎长大成人 and we've seen youngsters grow into almost adults now over the years.
所以我们的关系很好 So it's it's a beautiful relationship we have.
这头小象首先会跟着它的母亲 This young bull probably first followed its mother
像小牛一样穿过这里 through here as a calf.
现在他很放松， Now he is so relaxed,
他甚至花时间浏览礼品店 he even takes time to browse the gift shop.
在接待处办理登记手续 And check in at reception.
但很快，芒果的诱惑力太大了 But soon, the lure of the mangoes is too great.
像这样的树，对这里的野生动物至关重要 Trees like this are vital for the wildlife here.
树根从地下深处吸水， Their roots draw water from deep underground,
因此，即使在旱季，它们也能结出果实 so they can fruit even in the dry season.
能量和维生素C的重要来源 An important source of energy and vitamin C.
当大象们大吃大喝的时候， And while the elephants are feasting,
人们得到了一生中最疯狂的邂逅 the guests get a wild encounter of a lifetime.
当大象吃后， When the elephants have had enough,
就一声不响地离开了 they quietly leave.
和他们进来的方式一样 The same way they came in.
直接穿过接待处 Straight through reception.
大象是大吃货 Elephants are big eaters.
他们每天也要喝200升以上的水 But they also drink over 200 litres of water a day.
为此，就像这里所有的动物一样，他们依赖于河流 And for that, like all animals here, they rely on the river.
但赞比西不仅仅是一个喝水的地方 But the Zambezi is not only a place to get a drink.
对于胭脂红蜂鸟而言， For carmine bee-aters,
河岸提供了一个完美的居所 the banks of the river provide the perfect place to make a home.
这里可以容纳多达一千个巢穴 Their colonies can contain up to a thousand nests...
每只鸟都在沙质悬崖上掘进一米多深 ..each one dug into the sandy cliff face over a metre deep...
…这样可以保护鸟蛋，免受捕食者的侵害 ..where their eggs are protected from predators.
但在巢外，成鸟很危险 But outside the nest, the adults are vulnerable.
非洲鱼鹰不只在卡里巴湖上捕猎 African fish eagles don't only live on Lake Kariba -
他们在赞比西河沿岸随处可见 they can be found all along the Zambezi.
他们擅长的捕鱼技巧 The skills that make them so good at catching fish
同样适用于鸟类。 work just as well for birds.
在炎热天，河马沉浸在赞比西凉爽的河水 Hippos spend the hot days wallowing in the Zambezi's cool waters.
雌性群体往往生活在由单身雄性 Schools of females live together in a territory ruled
统治的地区 by a single male.
在大多数情况下，他们是平和的生物 And for the most part they are peaceful creatures.
直到雄性的权威受到竞争对手的挑战 Until the male's authority is challenged by a rival.
河马就会变得暴躁 Then hippos turn violent.
在河流的安全居所， In the safety of the river,
河马独霸一方 hippos are all-powerful.
但当太阳落山的时候，他们不再虚张声势 It's as the sun goes down that they start to lose their bravado.
河马必须吃草 Hippos eat grass.
每晚大约40公斤 About 40 kilos every night.
如果一直呆在河里，他们是吃不到的 They can't get that by staying in the river.
他们可能很大，有的超过两吨，但离开水 They may be huge - over two tons, but out of water
他们变得谨慎起来 they become cautious.
他们紧张什么呢？ So what are they nervous about?
随着夜幕降临 As the night progresses...
……它们会深入暗处 ..they travel further into the shadows.
每晚有五英里远 Up to five miles a night.
不发出声音 Not making a sound.
不久，河马在月光洒满的草地上安静地吃草 Soon, the hippos are peacefully grazing in moonlit meadows.
但他们正被严密盯视 But they are being watched.
狮子 Lions.
一群狮子在赞比西河的这一段巡逻 A pride of lions patrol this stretch of the Zambezi.
他们知道动物在河边来来往往喝水， They know that animals are moving to and from the river,
黑暗是他们最好的朋友 and the dark is their friend.
他们敢去打扰一头两吨重的河马吗？ But would they be bold enough to bother a two-ton hippo?
正是河马开始返回赞比西河的时候 It's when the hippos start heading back to the Zambezi
危机四伏 that they are most vulnerable.
狮子夜视能力很强 Lions have formidable eyesight.
随着夜色渐暗， As the night gets darker,
他们占了上风 they gain the advantage.
任何事情都是公平游戏 Now anything is fair game.
一头母狮试图谋取黑斑羚 A female lion tries for an impala.
混乱慌神中，河马们勉强到达安全的河里 Alarmed by the chaos, hippos scramble for the safety of the river.
但有一只孤单年轻的河马 But a young hippo is on its own.
正被死死盯上 That doesn't go unnoticed.
一头雄狮正试图接近它 A male lion is on to it.
还算巧 Just in time.
这只河马成功逃脱， The hippo makes good its escape,
回到赞比西河的安全水域里 safe once more in the waters of the Zambezi.
赞比西河继续前行，它将完成最后的... As the Zambezi journeys on, it performs a last
伟大的转变壮举 great feat of transformation.
流向莫桑比克的沿海平原 Flowing down on to the coastal plains of Mozambique...
分散成无数蜿蜒的小河 ..it spreads out into countless sinuous branches...
形成一个大三角洲 ..forming a great triangle that reaches all the way
最后全部达到印度洋 to the Indian Ocean.
赞比西三角洲 The Zambezi Delta.
赞比西之旅的最后一章 But this last chapter of the Zambezi's journey
曾经被过去所困扰 is haunted by the past.
从1977年到1992年， From 1977 to 1992,
这个地方遭到内战的蹂躏 this place was ravaged by civil war.
人类的付出是无法估量 The human cost was immeasurable.
对野生动物也造成了毁灭性的影响 And it had a devastating effect on wildlife.
在那场战争中，野生动物因肉食而被杀害， During that war, wildlife was killed for the meat,
但也有因为象牙而被杀，就如大象， but also be killed for the ivory, for example, elephants,
一切数量都急剧减少 everything just declined drastically.
多米尼克是一位热情的莫桑比克环保主义者 Dominique Goncalves is a Mozambican conservationist who's passionate
努力为这里的野生动物，创造更美好的未来 about forging a brighter future for the wildlife here.
她是进入赞比西三角洲中心地带的团队的一员， She is part of a team tasked to go into the heart of the Zambezi Delta,
去了解自从战争破坏至今-- to find out what has happened to the wildlife
--野生动物发生了什么 since the devastation of the war.
多米尼克是大象专家 Dominique is an elephant specialist.
她的计划是给主要的大象戴上卫星项圈 Her plan is to put satellite collars on key elephants
来了解他们的活动轨迹 to understand their movements.
这是保护三角洲所有野生动物的第一步 The first step in protecting all the wildlife of the delta.
如果你保护大象活动的区域， If you protect the area that an elephant uses,
你也保护一大片其他很多物种都在使用的区域 you're alsoprotecting a huge area that many, many other species are using.
首先，她必须找到它们 But first, she has to find them.
赞比西三角洲幅员辽阔 The Zambezi Delta is vast -
超过四千五百平方英里 over four and a half thousand square miles.
曾经，三角洲以其非凡的地理位置闻名于世 Once, the Delta was world-famous for its extraordinary
拥有大量的野生动物 wealth of wildlife.
大象成群结队，数量最多的 Great herds of elephant, and the largest numbers
是非洲的水牛 of buffalo in Africa.
自内战以来，很少有研究在这里进行 Since the civil war, few studies have been conducted here.
我们对残存的动物知之甚少，但仅仅半个小时的飞行 So little is known about what is left, but after just half an hour's flying,
有一个令人鼓舞的迹象 there's an encouraging sign.
大象 Elephants.
需要认真评估，我们可以给哪个大象佩戴 You really have to assess which individual we can work with.
所以你要综合考虑年龄、如果是雌性， So you have to think about the age and if it's a female, is she very,
是不是怀孕了？她有没有小象 very pregnant or not? If she has a young calf or not.
所以你不要给她施加额外的压力 So you don't want to put an extra stress on her.
这种飞镖含有一种速效镇静剂 The dart contains a fast-acting sedative.
当直升机降落时， And by the time the helicopter has landed,
大象已经睡着了 the elephant is already asleep.
快速检查它的呼吸， A quick check on its breathing,
他们开始工作 and they get to work.
必须快速工作 They must work fast.
虽然大象正在安详地睡觉， Though the elephant is sleeping peacefully,
他们越快，它就越快能回到象群中 the quicker they are, the quicker it can return to the herd.
当兽医在装项圈的时候， And while the vet is fitting the collar,
多米尼克收集尽可能多的信息 Dominique gathers as much information as she can.
这是研究这些三角洲大象的难得机会 This is a rare opportunity to study these delta elephants.
血样 Blood samples...
她的脚很小 Her feet is very small.
脚底尺寸， foot size,
记录它吃了什么是至关重要的 and getting a record of what it's been eating is a crucial
这是工作中不那么迷人的部分 but less glamorous part of the job.
全部要在15分钟内完成 All completed in just 15 minutes.
打鼾 SNORING
打鼾！ Snoring!
最后一次注射，会逆转镇静剂的效果 A final shot reverses the effects of the sedative.
他们现在只有几分钟的时间升空 They now have just a couple of minutes to get airborne.
在行程中，这么早遇到大象是一个充满希望的迹象 To encounter elephants so early in the trip is a hopeful sign
有不少数量在三角洲生存 that good numbers are surviving in the delta.
在接下来的几天里，多米尼克成功地将六头大象套住 In the next few days, Dominique successfully collars six elephants
来自不同的象群 from different herds.
很快，项圈开始产生效果 And straight away, the collars start to deliver results.
她能准确地看到每头大象和它们行踪 She can see exactly where each elephant and their herd travels.
他们需要什么空间来社交、吃饭 What space they need for socializing, feeding
并避免与人接触 and avoiding people.
带着卫星项圈在三角洲穿行， Travelling the delta with their satellite collars,
多米尼克的大象提供了关键的硬数据， Dominique's elephants are providing crucial hard data,
并开始绘制出她希望的空间 and are starting to map out the space that she hopes will
有一天保护三角洲的所有野生动物 one day protect all the wildlife of the delta.
即使在如此短暂的访问中， Even in such a brief visit,
能够让人惊鸿一瞥 there are tantalizing glimpses
三角洲里的一大群的生命 of the life the delta could hold.
A great herd,
数百头水牛- many hundreds of buffalo -
传说中曾在这里游荡的牛群的回声 an echo of the legendary herds that once roamed here.
以及这个地方的未来 And a vision of what this place could be.
这里，赞比西河 Here, where the Zambezi River
终于到了旅程的终点 finally comes to the end of its journey.
赞比西河非常重要 The Zambezi River is extremely important.
不仅在生物多样性和自然方面， Not only in terms of biodiversity and nature,
给我们文化、 but give us culture,
给我们生计、 give us, you know, livelihoods,
给我们很多东西 give us many things.
也许没有它，情况就不一样了 Perhaps without it, it wouldn't be the same.
这就是让所有人都为赞比西河感到自豪的原因， I think that's the thing that makes us all so proud to have the Zambezi,
这条非洲最大的河流， one of the greatest, biggest rivers in Africa,
就在这里结束，回到了属于它的地方。 to just finish here, next to home.
从赞比亚遥远角落的涓涓细流中 From a trickle of water in a far corner of Zambia...
这条大河克服了许多阻碍 ..this great river has overcome many obstacles on its
1500英里的旅程 1,500-mile journey.
非洲太阳的热量、 The heat of the African sun...
大陆中心崎岖的地质、 ..the rugged geology at the heart of the continent...
…现代世界的需求， ..the demands of a modern world...
但无论它流到哪里，都会带来生命和机会 ..but wherever it flows, it brings life and opportunity.
就像在旅程的最后 No more so than here at the end of its journey...
就像赞比西河的河水 ..as the waters of the Zambezi
他们终于融入 are finally carried away
印度洋 by the Indian Ocean.
地球大河摄制团队，面临的最大挑战之一 One of the biggest challenges for the Earth's Great Rivers team
是拍摄职业冲浪运动员米奇费波的骑行 was to film professional surfer Mikey February riding
赞比西波浪 the Zambezi Wave.
时机是关键 Timing was key.
这种独特的波浪每年只出现几天 This unique wave only appears for a few days each year...
…当水位随雨升降时 ..when water levels rise and fall with the rains.
它也非常偏僻， It's also incredibly remote,
而且很危险- and dangerous to reach -
沿着陡峭、参差不齐的悬崖 down steep, jagged cliffs
穿过这个星球上最汹涌的急流 and through some of the most ferocious rapids on the planet.
可能是一场协调上的失算，对于组织安排 It's been quite the logistic nightmare, maybe, to organise.
我们不得不推迟几次拍摄，只是因为河水还是太深了 We've had to postpone the shoot a few times just because the river
水位正在下降， water levels are dropping,
但没有下降到位 but they're not dropping quickly enough.
有这么一个小窗口可以瞄准， And there's such a small window to sort of aim for,
对于米奇来说，这波浪是可以冲浪的 for a wave that's surfable for Mikey.
团队决定明天是他们最好的出发时间 But the team decide tomorrow is their best bet to head off
寻找波浪 in search of the wave.
为了让每个人都安全到达那里 And to get everyone there safely are
这是赞比西河最有经验的河流向导 the Zambezi's most experienced river guides.
这也是 This one as well.
我们有四个摄像头，两架无人机，所有的电池，配件， We've got four cameras, two drones, all the batteries, accessories,
所有的卡片 all the cards.
有很多昂贵的工具 There's a lot of expensive kit
这可能会在赞比西河的底部损坏 that could end up at the bottom of the Zambezi.
起步还早， It's an early start,
然后团队前往峡谷边缘 and the team head to the edge of the gorge.
我们现在要去峡谷 We're going to go down to the gorge now.
请注意不要摔倒，不要滑倒，我们只是在梯子上走，所以 Please don't fall, don't slip, we're going just on ladders, so...
带领河流向导肖恩 Lead river guide Sean
向团队简要介绍前方100米处的险情 briefs the team on the treacherous 100 metre-descent ahead.
这是一块几乎垂直向下的巨石， It's an almost vertical drop down sheer rock,
沿着摇摇晃晃的木梯 and along rickety wooden ladders.
兜帽里一切都好吗？是 啊 All good in the hood? Yeah.
有人摔倒了吗？总是 Has anyone fallen? All the time.
总是 All the time!
开始了 It begins.
刘易斯是第一个跟随导游往下走的人 Lewis is the first to follow the guides down.
到目前为止，一切顺利 So far, so good.
实际上很害怕 Actually terrified.
但我们必须向前推进 But we must push forward.
团队现在怕的就是扭伤脚踝或更糟 The last thing the crew needs now is a twisted ankle or worse.
好啊？ 我没事 OK? I'm OK.
团队一直下到赞比西河 The team make it down to the Zambezi.
事实上，我从来没有像现在这样高兴过 Actually never been more happy to get into a raft.
但寻找河浪的旅程才刚刚开始 But the journey to find the wave has only just begun.
装载了珍贵的货物 Precious cargo loaded.
摇滚时间到了，走吧！ Time to rock and roll. Let's go!
一，二，三！ One, two, three!
起初，一切似乎都很平静，但汹涌的河水 At first, all seems calm, but turbulent water lies
就在拐角处 just around the corner.
河水开始奔腾起来 And the river starts to come alive.
强大的赞比西倾尽全力冲向他们 The mighty Zambezi throws everything it can at them.
哇，哇，哇，哇！ Whoa, whoa, whoa, whoa!
突然，橡皮艇 撞上了猛烈的浪涌， Suddenly, the raft hits a violent swell,
摄像师凯文跌进急流 and sends camera operator Kevin hurtling into the rapids.
他必须在河水把他冲走之前赶快捞出来 He must get out quickly before the river throws him
防止把他拖到岩石下面 into the rocks or drags him under.
他已经在安全员手里 But he's in safe hands.
多亏了导游的快速反应，凯文 Thanks to the quick reactions of the guide, Kevin's pulled
回到船上 back on board.
团队终于成功了 And the team finally make it
到赞比西波浪 to the Zambezi Wave.
经过数月的精心策划，我们终于到达了目的地 Months of meticulous planning went into arriving
正逢其时 at just the right moment.
但现在一切都取决于米奇 But now it's all up to Mikey.
太可怕了，而且，你知道，这有点危险 It's so scary, and it's so, you know, sort of dangerous.
当你看到这条河的照片，当水位非常低， When you see a photo of the river, when it's super low,
你能真正地看到，被真正击碎的岩石 you can actually see the rock that it actually breaks
在你的脑海里，它在起作用 off of, and it kind of plays on your mind.
你知道，显然必须戴头盔， You know, you obviously have to wear a helmet,
然后你还得穿救生衣 and then you also have to wear a life jacket.
在海里，你只需穿着潜水服或板短裤 In the ocean, you're just wearing a wetsuit or board shorts
或者别的什么--你肯定觉得自己不舒服 or something - you definitely feel out of your comfort zone.
但这不是米奇唯一关心的 But that's not Mikey's only concern.
鳄鱼，情况如何？ Crocodiles, what's the situation?
我的意思是，它们肯定在这里，我们不能忽视 So I mean, they're definitely here, and we can't discount them.
危险区域实际上就是这个水坑 The danger zone is actually just this pool.
它们不喜欢快速流动的水 They don't like the fast-moving water.
所以我想一旦你 So I think once you get
进入急流，你100%安全，这真的只是这个地区 into the rapids, you're 100%, it's really just this area.
但我的意思是，我们都在观察，一直在看，我们一直在问 But I mean, we've all been watching, we've been looking, we've spoken
渔民们，他们已经很久没有在这里看到鳄鱼了， to the fishermen and they haven't seen crocs here for ages,
所以我觉得我们很好 so I think we're good.
为了在合适的时间到达这里，米奇和团队 To get here at just the right time, Mikey and the team
从悬崖上下来， have descended cliffs,
在白水急流中航行 and navigated white water rapids.
但作为回报，他们经历了一个全新的一面 But in return, they experienced an entirely new side of one
地球上伟大的河流 of Earth's great rivers.
每个人都和这条河有着不同的关系， Everyone's got a different relationship with this river,
冲浪那一个是我 and surfing that wave is mine.
