In the shady camp grounds of Yosemite valley, climbers carved out a counterculture lifestyle of dumpster-diving and wild parties that clashed with the conservative values of the National Park Service. And up on the walls, generation after generation has pushed the limits of climbing, vying amongst each other for supremacy on Yosemite's cliffs.
'Valley Uprising' is the riveting, unforgettable tale of this bold rock climbing tradition in Yosemite National Park: half a century of struggle against the laws of gravity - and the laws of the land.

In just half a century, the human population has doubled to 7.4 billion, and during that time, astronaut and satellite photos have been capturing the startling changes on our planet. See how humans have made their mark reshaping the planet in our quest for new sources of food, power, and shelter.

Located beneath Russia's Ural Mountains, Orda Cave is legendary among divers for its unique beauty. The cave's waters are clearest in winter, when the land above lies frozen. With temperatures approaching minus 40 degrees, NHK attempts to film the cave for the first time ever using 4K cameras. Scientists give them insight into the cave's origins, enabling the crew to uncover the miraculous story of how the cave was naturally formed 300 million years ago by climate change and a shifting landscape.

Set in the wilderness of the Kamchatka Peninsula, the land of legends and the kingdom of wild brown bears, we follow the daily adventures of five wild brown bears. A mother bear and her two young ones, an adolescent male and an experienced male leader. Each of them have their own concerns and preoccupations. The mother must feed and protect her cubs, whilst all they want is to explore the big wide world out there, unaware of the dangers that lie ahead of them. The adolescent is coming of age and must find his place in the adult world, whereas the experienced male must constantly defend his supremacy and impose his strength.

The Sundarbans mangrove forest, in Bangladesh near the Indian border, is a tidal jungle where Ganges and Brahmaputra enter the Indian Ocean. Its has some 400 Bengal tigers - the largest population in the world, and the only to be hardly scared of men. The downside is tigers kill up the 50 Bangladeshis a year, even from neighbouring villages, so keeping them inside the reserve is key to long-term survival.
A recent project tries to train local mongrels, not pets but fiercely self-reliant dogs, to spot and even scare off tigers from villages. An individual tiger can turn into a man-eater in order to survive - this process may occur due to an injury or old age (and so cannot hunt agile prey) or even accidentally tasting human flesh.
