Watch Future Earth

This critical program will examine one of the key questions for our time - what will be the 21st Century's fuel of choice? Nuclear, Hydrogen, Wind, Solar are all possibilities. However each has its own drawbacks and all are vulnerable. This program will take us on an incredible journey as we explore new, old, borrowed and "blue" fuel sources -- from the blue oil sands of Canada, to the Solar City of Germany, to the promise of hydrogen fuel and nuclear fusion. And just as importantly, we examine how we can and will maintain the security of our power grids against the growing threats of terrorism.

Water. Without it, we die. Now, more and more, our vital supply of clean water is vanishing - evaporating. And what is left is dry earth, drought, fallow fields, starvation, hunger, nations on the move, other nations threatened. This program highlights some of the important new technologies being developed on a worldwide basis to bring clean, fresh water back to the a world that so desperately needs it as well as curtail the growing demand in resourceful and ingenuous ways.

Jeff Corwin hosts this program which tells the compelling stories of Earth's animal species, many of which are dangerously close to extinction. Today's rate of wildlife extinction is surpassed only by the mass extinction of dinosaurs, which occurred some 70 million years ago. Within the next 20 minutes, one unique species of animal life could simply disappear from our planet. Forever. But this special focuses not so much on extinction as survival - telling poignant stories of recovery - profiling, for instance, the California condor, as it gloriously takes flight to the skies once again after nearly disappearing forever. It also tells of the Herculean efforts by scientists to protect the last remaining black rhinos of Eastern Africa. The title 100 Heartbeats refers to an exclusive club whose main membership requirement is diminishing numbers -- species quite literally just a heartbeat away from extinction.

It's an expedition without parallel - sail to the top of the world and set anchor on an angry, icy sea. Then, spend 6 months of eternal Polar night aboard a marooned vessel, months fraught with the peril of polar bear attacks and 50-degree-below-zero temperatures. But this international expedition has a higher purpose then mere adventure. Its mission: find out why the world's climate machine - our North Pole - is melting - and doing so at an alarmingly fast rate. Journey to the End of the World is an in-your-face, adventure film that utilizes gripping footage shot during the expedition, state of the art CGI and expert interviews. It takes viewers on a long day's journey into night - and to a forsaken place that may well determine our planet's future. When all is said and done, this expedition provides scientific researchers with new data that enables them to better determine the rate of the Arctic Ocean ice's melt. And the results they gather is nothing short of astounding.
