简介：摄制队的专家们将带领你进入人迹罕至的北冰洋，在冰雪融化后初春，万物复苏呈现生机无限；超过百万牛羚和斑马奔腾于一望无际的大草原；素有海洋“威武之师”之称的海豚、鲨鱼、鲸鱼、海豹和鲣鸟，在深海中追捕猎杀数十亿沙丁鱼，在生生不息的大自然中上演弱肉强食的戏份；在奥卡万戈爆发的大洪水意外将4000平方英里的干旱平原，顷刻变成一个美丽的湿地。 随着环境恶化全球变暖，极地冰川正“被”加速消亡，北极熊们不得不冒险游得更远去捕食海豹，当镜头聚焦北极熊一家孤独而无助地被困于漂离的冰块上，假如浮冰随着水流漂离陆地，熊就会在挨饿淹死等困境中丧生。北极熊迷失在大海中的画面固然触动人心，但极地生态恶化程度只是冰山一角，需要更多的有心人去关注人类和自然和谐相处问题。
