你在河上和船上待了八到九个小时， You spend eight, nine hours on the river, on the boat,
你拿起网，你会看到空网 and you pick up the nets, and you see the empty nets.
会让我很沮丧 It's very frustrating for me.
但总是有希望的 But there is always hope.
今天确实是一个非常特别的日子 And today is a very special day indeed.
对 Yes!
他喊 HE SHOUTS
他们欢呼 THEY CHEER
难以置信的是，这个团队不是捕获了一条鲟鱼，还是两条 Incredibly, the team catch not just one sturgeon, but two.
比有名的白鲸小些，但同样珍贵 Smaller than the famous Beluga, but no less precious.
一条小鲟鱼， A young sterlet sturgeon,
估计在三到五岁之间 estimated to be between three and five years old.
还有一条布满星星的鲟鱼， And a starry sturgeon,
五到七岁之间 between five and seven years old.
哦 Woo!
这对小组来说，是一个巨大的成绩 It's a huge result for the team.
我们花了几个月的时间捕捉这些试样， We try to catch these specimens for months,
所以这是非常罕见的 so it's very rare.
我们很幸运，啊哈！ We are lucky. Ah-ha!
就像有人过生日一样 It's like when somebody have a birthday
你有了想要的很多人给的礼物，很多年 and you have this present that you want for many,many years...
他欢呼 HE CHEERS
你捕获的，不是一条，还是两条 ..and you have it, and it's not only one, you have both.
他们用宝贵的时间和鱼在一起 They use their precious time with the fish
记录重要数据， to record important data,
包括尺寸和重量 including size and weight.
小心地贴上标签， And carefully attach tags,
这样他们就可以监控鱼的活动 so they can monitor the fish's movements.
鲍里斯拉瓦并没有忘记这一特别相遇的重要性 The significance of this unique encounter is not lost on Borislava.
鲟鱼就像多瑙河上的旗舰 The sturgeons are like a flagship on the Danube.
所以，如果鲟鱼还在这里， So, if the sturgeon are still here,
我们将知道这条河是健康的 we will know that the river is healthy.
还有一条路可以走 There is a way to go.
但现在，鲍里斯拉瓦可以庆祝这场小小的胜利 But, for now, Borislava can celebrate this small victory.
再见，宝贝 Bye, baby.
希望保护工作再努力， It's hoped that conservation efforts,
比如重新补充和保护迁徙路线， like restocking and protecting migration routes,
也许会给这些标志性的鱼一个未来 might just give these iconic fish a future.

我把这条大河叫做家 It's this mighty river that I call home.
它的意义在各个方面都非常重大 The meaning of it is just extremely big in every way.
洛克一生都生活在萨瓦河上， Rok has lived all his life on the Sava river,
多瑙河的主要支流之一 one of the Danube's major tributaries...
他和其他人一样清楚 ..and he knows it as well as anyone.
萨瓦河真的很特别 Sava is really special
因为它把所有在山脉高处的东西 because it brings everything that's stored high up in
一直带到谷底 the mountains down to the bottom of the valley.
没有萨瓦河，这个山谷就不会是绿色的 Without Sava, this valley wouldn't be green
我们就不会有牧场， and we wouldn't have pastures,
更不会有旅游业了 and we wouldn't have tourism.
我们不会划独木舟， We wouldn't be kayaking,
不会去捕鱼， we wouldn't be fishing,
我们就听不到河流的声音了 we wouldn't be enjoying the sound of the river.
这基本上是这个地方的精华 It's basically the essence of this place.
呜呜呜！ Woohoo-hoo!
但不仅仅是洛克利用了河流的力量 But it isn't just Rok who takes advantage of the power of rivers.
多年来， Over the years,
工程师们已经在欧洲沿线利用了它们 engineers have harnessed them across Europe
作为一种能源 as a source of energy...
筑坝- ..building dams -
一个有价值的低碳电力来源 a valuable and low carbon source of electricity...
…以及储存水和帮助控制洪水 ..and a way to store water and help control flooding.
水坝总是有好处，也带来了坏处 But dams will always create winners and losers.
这些大坝有着复杂的含义 And these barriers have complex implications...
…戏剧性地重塑了河流上下游的生态 ..dramatically reshaping the river's ecology up and downstream...
汽笛声 WHISTLE TOOTS
这是一个问题 ..which is a concern
对于许多生活在这些河流旁边的人来说 for many who live alongside these rivers.
萨瓦河已经有十多座大坝 The Sava river already has over ten dams
还有另外十个的计划 and there are plans for ten more.
对洛克来说， For Rok,
这些大坝对野生动物造成了损害 the damage caused by these barriers to the wildlife
这条河的生态意义太大了，不容忽视 and ecology of the river is too great to ignore.
看到这一幕会很难过 It would be sad to see
对这条河的破坏，你知道吗？ such destruction to this river, you know?
这条河为这些动物提供了家园 The river provides home for these animals.
你知道，他们不能去别的地方 You know, they can't go anywhere else.
如果一只鸟生活在沙砾上，好！ If a bird lives on a gravel bar, well,
它只能生活在沙砾上 then it lives on a gravel bar.
如果水獭需要河里有鱼， If an otter needs a river with fish, well,
然后，这条河能提供 then that's what this river provides,
这就是为什么保护这些河流，是如此重要 and that's why it's so important to protect these rivers.
当我们意识到 And by the time we realise
产生的负面影响，已经太晚了 the negative effects, it's already way too late.
它只是 And it just...
让我心碎 呃 ..breaks my heart and mind. Erm...
因为如果这些筑坝计划得以实施， Because if these plans go ahead,
我现在坐的地方将在水下 the place where I'm sitting right now will be underwater.
不仅仅是我，我是排队最后一人，你知道吗？ And it's not just me, I'm the last in line, you know?

多瑙河及其支流 The Danube and its tributaries
已经有700多座大坝 have seen more than 700 dams
沿着他们的路线建造了水坝 and weirs built along their course.
这些人造大坝，严重影响了野生动物 The effect of these man-made structures on wildlife is significant.
面对这一点，洛克决定采取行动 Faced with this, Rok decided to do something.
我意识到没有行动的情感 I realised that emotion without action
最终会毁掉你的灵魂， is basically going to ruin your soul eventually,
我打电话给我的朋友说， and I called a bunch of my friends and I said,
“听着，伙计们，这些河流会被毁掉 "Look, guys, these rivers are going to be destroyed without
“如果我们不采取行动，没有人知道 ” "anybody knowing if we don't do something."
欢呼 CHEERING
我们意识到问题的核心是 We realised that the core of the problem is that
没有足够的人花时间在河这个问题上 there's not enough people spending time next to the river
我们说，“好吧，我们要让人们漂流 and we said, "Well, we're going to take people rafting.
“我们要带人们去河边野餐” "We're going to take people picnicking by the river.
“我们要带他们去划船、游泳，随便什么” "We're going to take them kayaking, swimming, whatever."
你首先需要知道一个地方 You first need to know a place
然后爱上这个地方 to fall in love a place
只有到那时，你才会觉得有必要保护它 and only then you're going to feel the need to protect it.
洛克的倡议，已经帮助阻止 Rok's initiative has already helped stop
在该地区修建12座新水坝 the building of 12 new dams in the region.
还有他家乡河上的一座水坝， And one of the dams on his home river,
萨瓦河现在被推迟了 the Sava, has now been delayed.
重点把注意力集中在 But it's also focused attention on
让河流自然流动的重要性 the importance of allowing rivers to flow naturally.
除了湖泊和湿地， Along with lakes and wetlands,

却拥有25%的脊椎动物 ..and yet are home to a quarter of all vertebrate species...
包括超过一半的鱼类 ..including over half of all species of fish.
水力发电被视为可再生能源 Hydro is seen as a renewable source.
他们的意图可能是好的， Their intentions might be good,
现实是我们现在做的基本上是， but the reality is that what we're doing is, basically,
我们正在破坏我们环境中最重要的部分 we're destroying the most important parts of our environment.
水电是主要的低碳电力来源， Hydropower is a major low-carbon source of electricity,
正如决策者逐渐理解的那样 but as decision makers are coming to understand
自由流动的河流的价值 the value of free-flowing rivers...
…它的用途正在重新评估 ..its use is being reassessed.
以及可再生技术的革命 And a revolution in renewable technologies
可能会提供令人兴奋的选择 may offer exciting alternatives...
…比如像太阳能 ..like solar...
…风力和电池存储， ..wind, and battery storage,
这一切都有助于保持河流的流动 which could all help keep rivers flowing.
我对未来的希望是人们意识到 My hope for the future is that people realise
河流对人们自己的重要性 the importance of rivers for themselves...
还有所有的野生动物和植物， ..then also for all the wildlife and plants,
无论旁边住着什么 and whatever lives next to it...
因为时间不多了 ..because the time is running out.
