Japan has more than 100 active volcanoes--two in particular may be on the verge of unleashing a devastating sequence of deadly eruptions and secondary earthquake activity. Join intrepid volcanologist Tom Pfeiffer's dangerous and exhilarating journey to the foot of these angry giants.
No music. No commentary. HOMO SAPIENS is a film about the finiteness and fragility of human existence and the end of the industrial age, and what it means to be a human being. What will remain of our lives after we’re gone? Empty spaces, ruins, cities increasingly overgrown with vegetation, crumbling asphalt: the areas we currently inhabit, though humanity has disappeared. Now abandoned and decaying, gradually reclaimed by nature after being taken from it so long ago.

Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.
