Eden: Untamed Planet

BBC2, 7.10pm

This stunning new six-part series takes viewers into a handful of places largely untouched by man. Alaska, the Namib Desert, Patagonia, Luangwa Valley and the Galapagos are to come, but the run begins in Borneo's rainforest, home to more than 40,000 species of plants and animals, with more being discovered on an almost daily basis.
