NOVA
Life’s Rocky Start

 

From the first sparks of life to the survival of the fittest, unearth the secret relationship between rocks and life. NOVA goes around the world and back in time to investigate how minerals are vital to the origins and evolution of life.

 

Four and a half billion years ago, the young Earth was a 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. How did it happen? NOVA joins mineralogist Robert Hazen on the rocky trail to resolve this enduring mystery. As Hazen journeys around the globe, he advances a startling and counterintuitive idea – that the rocks beneath our feet were not only essential to jump-starting life, but then, as microbes flourished and took over the biosphere, life helped give birth to hundreds of minerals we know and depend on today. This intriguing perspective of the co-evolution of Earth and life is reshaping the grand-narrative of our planet’s story.

 

EARTH A NEW WILD
Oceans


This five-part series takes a fresh look at humankind’s relationship to the planet’s wildest places and most fascinating species. Dr. M. Sanjayan, a leading conservation scientist, takes viewers on a stunning visual journey to explore how humans are inextricably woven into every aspect of the planet’s natural systems. The series features spectacular natural history footage from the most striking places on Earth, filming encounters between wild animals and the people who live and work with them. With up-close looks at a range of species, from giant pandas to humpback whales and African lions to Arctic reindeer, Sanjayan reveals that co-habitations with animals can work – and be mutually beneficial.

Oceans
Reporting from Palmyra Atoll (one of the most remote coral atolls on Earth), the Bahamas, and from New York Harbor, host Dr. M. Sanjayan  introduces a vibrant community of scientists, engineers and fishermen who are discovering new ways to help maintain the remarkable productivity of oceans. He is aware of the vast threat facing our oceans, but standing in the water playing mid-wife to a lemon shark is just one of the moments that give him hope that we can change the way we influence our oceans – the wildest habitat on Earth.

Sinkhole: Buried Alive

 

In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole – a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes like Swiss cheese. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way – often catastrophically. Sinkholes have swallowed highways, apartment buildings, horses, camels, even golfers, with monster-size holes cracking the earth from Siberia to Louisiana. With compelling eyewitness video of dramatic collapses, NOVA follows scientists as they explore the underlying forces behind these natural disasters, traveling the globe to investigate what it’s like to have your world vanish beneath your feet.
