All three episodes of this remarkable series are presented together in a single video on our website. This powerful documentary gives voice to the people of New Orleans, from the terror and chaos of the storm to the long, painful aftermath. As Hurricane Katrina approaches, the city orders a voluntary evacuation that soon becomes mandatory, but for many it is already too late. Trapped by rising waters, stranded in shelters like the Superdome, powerless without federal help, thousands are forced to endure the unendurable. Yet it is also a story of resilience, of neighbors helping neighbors, of grief and recovery. Two decades later, survivors reflect on what they lost and how their culture and communities have been forever changed. With rare footage and emotional testimonies, this film becomes essential viewing.
Plants that have developed to thrive in the desert, including cacti that grow in the shade of other trees and collect water in pleated trunks that expand and contract - but can also find themselves a host to other plants, like desert mistletoe. This programme also reveals how tobacco plants being eaten by caterpillars are able to summon the creatures' natural predators, and how tumbleweeds roll across the landscape, only unfurling and growing when they encounter rain.
What might happen if the first manned mission to Mars crashes hundreds of miles from the rocket that would take them back home? Could they survive the crash, and travel across the brutal Martian surface to their home ship? We'll show what the astronauts would have to do to survive dust storms and space radiation, while extracting vital resources like water from the Martian soil itself. It's a dramatic vision of the very near future, where survival can depend on pre-industrial technology and human ingenuity.
As tides rise and fall twice a day, vast amounts of water swirl around the earth. This is a huge energy source that's currently largely untapped. An estimated 3000 gigawatts are available to be harvested globally, enough to power a third of the earth's homes. Yet compared to wind and solar, the technology needed to harness tidal power is still in its infancy. The power of the ocean’s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water.
The Namib Desert is one of the oldest deserts and also one of the most diverse. With 50ºC (120ºF) temperatures and half a millimetre of rainfall annually, we see how this is possible. Half the size of Oklahoma, from its Skeleton Coast through the sea of sand to the haze of distant mountains this apparently forbidding desert hides secret water sources.
World War II is a watershed event for Latino Americans with hundreds of thousands of men and women serving in the armed forces, most fighting side by side with Anglos. In the Pacific, East L.A.'s Guy Gabaldon becomes a Marine Corp legend when he singlehandedly captures more enemy soldiers than anyone in US military history. But on the home front, discrimination is not dead: in 1943, Anglo servicemen battle hip young "Zoot suitors" in racially charged riots in southern California
