These are the last humans who have stayed outside ‘civilisation'

A NEW REPORT BY SURVIVAL INTERNATIONAL, Uncontacted Peoples: At the Edge of Survival, is the latest accounting of the human story - and it is a historical document of unparalleled power. It reveals that at least 196 groups in the world are still uncontacted, most of them gravely threatened by logging, mining and drilling for oil. These are the last human beings who have stayed outside ‘civilisation’ since the violence of the West reached across the globe after 1492.

The report cast my mind back 25 years to when we made a series of four films telling the story of the Spanish conquest of the Americas. Cortés, Pizarro, Orellana, Cabeza de Vaca: these were men who experienced some of the most incredible adventures in human history. We tracked them on the ground, following in their footsteps over the Andes, up Inca trails to lost cities, and rafting down the Amazon.
