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.

Jungles cover roughly three per cent of our planet yet contain 50 per cent of the world's species. High-definition cameras enable unprecedented views of animals living on the dark jungle floor. In the Ngogo forest the largest chimpanzee group in the world defends its territory from neighbouring groups. Other jungle specialists include parasitic fungi which infiltrate an insect host, feed on it, and then burst out of its body.

Animals and plants in the Galapagos have evolved the most surprising ways to cope with the profound geological and climatic forces.

The youngest foot soldiers for the Lord are shown in their native environment in this documentary. Becky Fischer is a children's pastor who runs 'Kids on Fire,' a summer camp for evangelical Christian children in North Dakota. Fischer believes in the political and moral importance of a Christian presence in America, and uses her camp to reinforce the religious training most of her charges are already receiving at home (the majority of the campers are home-schooled by their parents).
Using video games, animated videos, and group activities to help put her message across, Fischer encourages the kids to pray for the President and his Supreme Court appointees while urging them to help 'take back America for Christ.' For the most part, the children seem reasonably ordinary beyond the fact they pray with uncommon fervour and sometimes speak in tongues.
Along with Fischer and her cohorts, Jesus Camp features interviews with Ted Haggard, an evangelist and advisor to George W. Bush, and Mike Papantonio, a Christian talk-show host who believes the right-wing slant of many Christian evangelists is taking the church into a dangerous direction.

From the makers of Walking With Dinosaurs comes an epic and entertaining new exploration of early life on Earth, revealing that before the age dinosaurs, a succession of fantastical animals and plants ruled the planet. A time when a two-ton predatory fish came on land to hunt, when four-metre sea scorpions sliced sushi in the shallows and when just one species of lumbering reptile represented 80 per cent of all life. For the first time, this special two-hour presentation uncovers and recreates these creatures and the bizarre world they inhabited.

A visit to the Amazon jungle - the world's largest rainforest and home to the widest variety of plants and animals on Earth. he diversity of life in the jungle is so great that in just two square miles scientists have counted 3,000 varieties of ants, 530 types of birds and 11 species of monkey. But despite the huge range of life that flourishes here, survival is never easy.
