In 1954 young David Attenborough was sent on an expedition to find animals for the London Zoo. He was sent to Guyana, Indonesia and Paraguay. It was also filmed for the BBC and marked the start of his amazing career as a natural historian and scientist. His adventures include run-ins with cannibal fish, aggressive tree porcupines, feeding a baby orangutan and plenty more besides. Told in his gently self-effacing and witty way he also discusses the changing attitudes to zoos, and the role that television has played in the increased knowledge of the natural life of our beautiful planet.
