Broadcast 2012. In this episode, Chris weaves a spellbinding account of how the very special conditions that exist in the rainforest have allowed vast colourful communities of animals and plants to evolve. And he reveals one particularly extraordinary web of life centred on a tree, the Brazil nut tree. It is one of the mightiest trees in the Amazon but it can only survive thanks to a little rodent called agouti, an orchid and a very unusual bee.

Secrets of Our Living Planet showcases the incredible ecosystems that make life on Earth possible. Using beautifully shot scenes from all over the world, naturalist Chris Packham reveals the hidden wonder of the creatures that we share the planet with, and the intricate, clever and bizarre connections between the species, without which life just could not survive. For him, what is really beautiful about nature is not the amazing animals and plants that we share the planet with but the hidden relationships between them. Discover why a tiger needs a crab; or why a gecko needs a giraffe. Each week Chris visits one of our planet's most vital and spectacular habitats and dissects it, to reveal the secrets of how our living planet works. (www.youtube.com)
