When Andres Ruzo was a boy growing up in Peru, his grandfather told him fantastic stories about the Amazon - including a city of gold, and a river that boils.
Years later, Ruzo is a geoscientist, explorer, and a storyteller himself - and he finds the boiling river. He talks to Wallace about the sacred waterway, the indigenous people who protect it, and the battle to save the Amazon jungle. Andres Ruzo has written a TED talk book on his adventures, called The Boiling River: Adventure and Discovery in the Amazon.
