Season 1

For the privileged few who have looked down at the Earth from space, the thin blue line of our planet's sets the Earth apart from every other planet we've seen. It sustains life. The story of how the Earth creates and regulates that oxygen rich-atmosphere is mind-blowing: A flying river, a global dust storm, a collapsing glacier and the most important creature you've never heard of. All connected together to allow life and the planet to breathe.
