非凡地球

 The thin blue line of our planet that we can see from space is what makes our Earth unique in the whole universe. The oxygen in the atmosphere sustain all lifeform on the planet. See how a flying river in South America, a shifting dust-storm through the Atlantic, collapsing glaciers in the Arctic and the tiniest yet the most crucial creature in the world help us all just to breathe. 最新最经典好看的影视剧-可搜影视为您提供非凡地球在线观看，更多影视请访问www.keso.org
