At the height of the Zambian dry season, three lionesses in the Nsefu pride are pregnant. Even with protection from fellow lions, the stakes couldn't be higher, from cub-hungry predators like leopards and hyenas to the hunting duties necessary to sustain the group. Can the pride meet the demands of their growing population?
Welcome to an extreme landscape of rock, ice and snow. We tour the mightiest mountain ranges, starting with the birth of a mountain at one of the lowest places on Earth and ending at the summit of Everest. Find out how some of the most secretive animals rise to the challenge of mountain life. Share one of Earth's rarest phenomena, a lava lake that has been erupting for over 100 years. The same forces built the Simian Mountains where we find troops of gelada baboons nearly a thousand strong. In the Rockies, grizzlies build winter dens inside avalanche-prone slopes and climb the peaks to devour abundant summer moths. In another world first, the programme brings us astounding images of a snow leopard hunting on the Pakistan peaks.
An elaborate river portrait-in this case of one of the greatest rivers of Europe. An epic journey of discovery into the continent's unknown wild lands, "Danube - Europe's Amazon" shows how the river's famous currents helped sculpt the incredible landscapes, and it links them together.
