The Himalayas is one of the most expansive and storied regions in the world. It's also a place that we're hugely dependent on, providing billions of people with fresh water. Because of its significance, civilisations throughout history have sought to conquer it. What forces have exerted control over 'The Roof of the World'? And what is it about this place that has fascinated outsiders for centuries? Dan speaks with John Keay, journalist and author of Himalaya: Exploring the Roof of the World to explore the intersections of culture, society and nature that makeup one of the world's last great wildernesses.
