Asia

David Attenborough turns his attention to life in Asia, the planet's most varied and extreme continent, which stretches from the Arctic Circle to the equator. Walruses gather in huge numbers in the frozen north and brown bears roam around remote Russian volcanoes, while the deep jungle provides sanctuary for the last few Sumatran rhino. There is also a glimpse of rarely seen creatures, from yeti-like golden snub-nosed monkeys in the mountain forests of China to a bizarre predator in the baking deserts of Iran.
