- And it needs to be,
而且必须如此 - for these young caribou have now started a journey
这些幼鹿开始了一场 - that will last a lifetime.
终其一生的旅程 - Forever chasing the seasonal growth of the grass
永远追寻着他们所需要的 - on which they depend.
季节性生长的青草 - Like all grassland creatures, they are at the mercy
和其他草原生物一样 他们依赖着 - of these unpredictable but ultimately bountiful lands.
这变化莫测而又极其慷慨的大草原
