On 26 April 1986, reactor number four at the Chernobyl Nuclear Power Plant blew up. Forty-eight hours later the entire area was evacuated. Over the following months there were stories of mass graves and dire warnings of thousands of deaths from radiation exposure.
Science in Antarctica will shut down for the winter. Scott Base has plenty of logistics to manage in order to send teams out to finish their missions for the season. The USS Coast Guard crew is challenged by their aging ship as they try to finish cutting a channel in the ice before they escort the ship in. The Mt. Erebus team struggles to salvage as much data as they can before they go home.
"Eighty percent of us now live in an urban setting, and I think that the solution to our environmental problems is not to say 'we've got break down cities and get everybody back to the land' – that would be disastrous – but we have to make cities our major habitat…we have to make them more in balance, I think, with the rest of the things that keep us alive." David Suzuki Cities are where most Canadians live. And, as we head into the future, how we adapt to the needs of expanding cities will have a huge impact on their livability. Food, land use, housing, energy, waste – how we tackle these issues will determine whether our cities evolve, or whether they decline. In a new instalment of Suzuki Diaries, David and his daughter, Sarika, set out to discover whether some of Canada's biggest cities are ready for the challenges of the future.
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.
