The highest mountain range in the world, the Himalayan range is far reaching, spanning thousands of miles, and holds within it an exceptionally diverse ecology. Coniferous and subtropical forests, wetlands, and montane grasslands are as much a part of this world as the inhospitable, frozen mountaintops that tower above. The word Himalaya is Sanskrit for abode of snow, fitting for a stretch of land that houses the world’s largest non polar ice masses. Extensive glacial networks feed Asia's major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They're also crucial for our survival.

An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

Why do some animals build structures and others don't? And how do animals decide where to build? Animal homes need to be safe and secure, protection from predators and the weather.

Each year, far from human eyes, a remote expanse of Botswana's Makgadikgadi salt pans hosts one of Africa's last great spectacles when thousands of striped nomads wander the breathtakingly beautiful but barren landscape. It is only by the grace of isolated summer rains that the zebras can survive here at all. Family groups gather together to follow the rains, driven by a constant search for better grazing on islands of grass that dot the pans. Meerkat families watch the zebras come and go, and families of lions wait for them along their grueling trek, hoping for a chance to bring one down. Their journey is one that is sometimes limited by the fragility of new life, but always made possible by the strong family ties that help animals survive in one of Africa's most surreal landscapes. It's a tale of loyalty and sacrifice, of home and exile, of death and new life, in southern Africa's largest zebra population.

The undersea world has often been depicted as a dangerous place filled with lethal predators. A world where sharks are mindless eating machines. A world where the only relationship between species is that big fish eat little fish. Of course, stories of sensational danger and violent predation are seductive to wildlife film audiences. But is that what the ocean is really like?
