“The uncontacted and isolated tribes represent a true treasure,” National Geographic writer and author Scott Wallace says in this episode. “Their knowledge of the rainforest, of the medicinal properties of the plants, of all the animals, their spirit world — all of this is an incredibly rich trove of knowledge.”

Wallace's book The Unconquered tells the story of an expedition into remote Amazon rainforests undertaken by the head of Brazil’s Department of Isolated Indians to gather information about an uncontacted tribe known as “the Arrow People” in order to protect the indigenous group from the ever-advancing arc of Amazonian deforestation.

He joins the podcast to share his experiences and to discuss this particularly perilous time for indigenous peoples in the Amazon.
