这是一只雪豹 A snow leopard.
它已经几天没有进食了 He hasn't eaten in days.
这可能是它的最后一次机会 This may be his last chance.
水深火热的星球
我现在位于海拔3200米的高度 I'm two miles above sea level here,
这里的环境十分恶劣 And it is brutal.
天寒地冻 荒无人烟 呼吸困难 Cold, desolate, hard to breathe.
但对许多动物来说 这里就是家园 But, for some, this is home.
高山是地球上最为恶劣的 Mountains are one of the most hostile environments
生存环境 On our planet.
由于全球气温变暖 Now, with the rise in global temperatures,

春天早早地到来了 Spring has arrived here early.
对于在山地繁殖的白颊黑雁来说 And that's bad news for the barnacle geese
这是个槽糕的消息 That breed in these mountains.
很多鸟巢毁于一旦 Many nests have failed...
但这一家幸免于难 But not this one.
巢中一共三只雏鸟 Three chicks.
成功地破壳而出 They're lucky to have made it.
由于春天来得太早 Forced by the early spring,
白颊黑雁父母急急忙忙完成了迁徙 The parents rush to their migration.
它们抵达时已经筋疲力尽了 They arrived exhausted.
雌鸟又连续25天时间孵卵 The female sat on the eggs for 25 days.
它的体重现在减少了30％ She's lost 30% of her body weight.
但还有一个更为艰难的挑战 But for this family,
在等待着这个家庭 The greatest challenge is still to come.
白颊黑雁父母选择在高达400尺的峰柱顶上筑巢 The parents chose to nest on this 400 foot pinnacle.
只有这样才能避开掠食者 It's the only way to evade predators.
但这也存在一个难题 Just one problem...
它们要前往1.6公里外的河边 The grass they eat is a mile away,
才能吃到青草 By the river.
这样白颊黑雁父母就很难飞回喂养巢中的雏鸟 And barnacle geese can't feed their young in the nest.
雏鸟如果36小时没有进食 If the chicks don't feed within 36 hours,
就会饿死 They'll starve.
而这些雏鸟还要再过一个月才能学会飞行 And these chicks won't be able to fly for another month.
它们的父母既然能活着 就证明雏鸟们会有出路 The parents are living proof there is a solution.
只是并不轻松 Just not an easy one.
爸爸首先示范 Dad leads the way.

但是更难避开岩石 But it's much harder to avoid the rocks.
这只雏鸟无处逃脱 For this chick, there will be no escape.
只有一只雏鸟还活着 The third and last surviving chick.
积雪为它提供了缓冲 但是并没有让它停下来 The snow cushions the impact, but offers no grip.
在悬崖上出生的雏鸟只有大约一半 Only around 50% of chicks hatched on these cliffs
能成功存活到足月 Make it through the first month.
这里的季节变化越发难测 With the seasons increasingly unpredictable,
能幸存下来的雏鸟就更少了 Fewer chicks will survive.
但是至少这只雏鸟 争取到了一线生机 But this chick, at least, has defied the odds.
世界各地的高山动物都受到了 A changing climate is affecting life in mountains
气候变化的影响 Across the world.
冬季即将结束 Late winter.

岩羊 Blue sheep.
在如此炎热的天气下 雪豹跑不了很远 In this heat, he can't run far.
它需要缩小和猎物之间的距离 He needs to close the gap.
它的伪装派上了用场 His camouflage helps.
但是这里的掩蔽物太少了 雪豹很难靠近 But with so little cover, it's hard to get close enough.
它起跑得太早了 He ran too early.
气温太高 它很难展开追逐 And it's too hot to give chase.
和山区的很多动物一样 Like all who live here,
这只雪豹的命运和气候息息相关 His fortunes are linked to the mountain climate.
即使气候发生了很小的改变 也会造成严重的影响 And even small changes can have dramatic consequences.

团结的力量是惊人的 This united force is overwhelming.
老狒狒胜利了 The old male is victorious.
维持统治并非易事 But it's tough at the top.
随着气温变暖 它们食用的青草在更高海拔的地区才有 As the climate warms and the grass they depend on retreats higher,
届时这里的生存战斗势必更加激烈 Their battle for survival will only intensify.
