Revisited: How to save the Amazon episode two: the magic and mystery

Loading player...
Jon Watts, the Guardian’s global environment editor, goes in search of answers to the question the journalist Dom Phillips was investigating when he was murdered: how to save the Amazon? In episode two of this miniseries from June 2025, Jon meets the people trying to make sure the rainforest is worth more standing than cut down – from a government minister attempting to establish Brazil’s ‘bioeconomy’ to a startup founder creating superfood supplements and a scientist organising night-time tours hunting for bioluminescent fungi. Jon explores new ways of finding value in the forest and asks whether they will be enough to secure its survival. Help support our independent journalism at theguardian.com/sciencepod
