Cities - Surviving the Urban Jungle • episode "8/8" • Human Planet

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.

In May 2018, Kilauea volcano erupted, obliterating neighborhoods with devastating force and uprooting thousands of local residents. It is Hawaii's most destructive volcanic eruption in generations. How can one of the most beautiful places on Earth suddenly transform into a roaring inferno, sputtering molten lava and bombs of volcanic rock the size of refrigerators? On the ground in the early days of the eruption, NOVA joins scientists and residents alike on a breathtaking journey to investigate Kilauea's recent spike in activity. Along the way, some of Hawaii's biggest secrets are revealed: Why did these geologically distinctive volcanoes form in the middle of the Pacific? How did life establish itself on the remote islands? What does this tell us about the future of Hawaii? And what dangers yet lurk for the inhabitants of the island paradise?

For centuries we have dreamt of reaching the centre of the Earth. Now scientists are uncovering a bizarre and alien world that lies 4,000 miles beneath our feet, unlike anything we know on the surface. It is a planet buried within the planet we know, where storms rage within a sea of white-hot metal and a giant forest of crystals make up a metal core the size of the Moon.
