Investigates the greatest vanishing act in the history of our planet - the sudden disappearance of the dinosaurs 66 million years ago. Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link.

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.
