David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 3: Congo) The very heart of Africa is covered in dense tropical rainforest. The animals that live here find the most ingenious ways to carve out their space in a claustrophobic landscape. Danger lurks in every shadow, but some animals thrive here, from honey-stealing chimps to birds with a lineage as old as the dinosaurs, thundering elephants and kick-boxing frogs. Here in the Congo, no matter how tough the competition, you must stand up and fight for yourself and your patch.

What is it that makes things alive? What if we made robots that could sustain themselves? What if they could mine metals or recycle old robots, reprogram and remake themselves?

Concludes with a look at the work of people striving to protect Asia's endangered wildlife, and what routes conservation could take in the future. In Japan, scientists take pregnant sharks, killed accidentally in fishing nets, and rescue their unborn young in an incubating system that simulates a womb. The programme also visits a village that used to be a hotbed of poaching and is now a centre for bird tourism.

In the final film, he reflects on the dramatic impact that humankind has had on the natural world within his own lifetime. He tells the surprising and deeply personal story of the changes he has seen, of the pioneering conservationists with who he has worked - and of the global revolution in attitudes towards nature that has taken place within the last six decades. In a journey that takes him from the London Zoo to the jungles of Borneo, Attenborough reveals what inspired him to become a conservationist. He remembers classic encounters with mountain gorillas, blue whales and the giant tortoise, Lonesome George. These are all characters that have helped to change public attitudes to the natural world.
