Finding Eden: a journey into the heart of Borneo

50 years ago the interior of Borneo was a pristine rainforest inhabited by uncontacted indigenous tribes and virtually tame wildlife.

It was into this 'Garden of Eden' that Robin Hanbury Tenison led one of the largest ever Royal Geographical Society expeditions, a huge undertaking which triggered the global rainforest movement and illuminated how vital rainforests are to our planet.

For 15 months, he and a team of scientists immersed themselves in a place and a way of life that is on the cusp of extinction.

Much of what was once a wildlife paradise is now a monocultural desert, ruined by logging and the forced settlement of nomadic tribes, where traditional ways of life and unimaginably rich and diverse species are slowly being driven to extinction.

This is a story for our time, one that reminds us of the fragility of our planet and of the urgent need to preserve the last untamed places of the world.
