One man has seen more of the natural world than any other. This unique feature documentary is his witness statement. Having spent decades traveling the globe and producing some of the most memorable documentaries of all time, few people know the natural world quite like David Attenborough. That’s why he’s so concerned about the issue of climate change, which will threaten humanity’s very survival unless urgent action is taken to halt the damage it has already caused. Attenborough’s latest offering, A Life On Our Planet, is a reflective piece, looking back on his 94 years on Earth and sending a desperate appeal for help in securing its future.
Six different teams of scientists arrive on the continent after years of planning. The continent is home to the coldest, windiest, driest conditions on the planet, and without Scott Base as their central hub, these teams wouldn't survive. Each team's results could have massive implications to better understanding how climate change is affecting life around the world.
The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
Between the blue sky above and the infinite blackness beyond lies a frontier that scientists have only just begun to investigate. In "At the Edge of Space," NOVA takes viewers on a spectacular exploration of the Earth-space boundary that's home to some of nature's most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites.
Professor Iain Stewart uncovers clues hidden within the New York skyline, the anatomy of American alligators and inside Bolivian silver mines, to reconstruct how North and South America were created. We call these two continents the New World, and in a geological sense they are indeed new worlds, torn from the heart of an ancient supercontinent - the Old World of Pangaea.
