5 x 1-Hour Lectures from Canada by Wade Davis, an Anthropologist, Ethnobotanist and an AMAZING story-teller.
The series is called “The Wayfinders: Why Ancient Wisdom Matters in a Modern World” and takes the listener on a profound journey through the ‘ethnosphere’ – spacially and temporally!
These presentations are very enlightening and have every chance to change your perception of human cultures (and collectively as a species) for ever
