In this week's episode we talk with Enric Sala, Explorer in Residence at the National Geographic Society, who has written a terrific new book, The Nature of Nature: Why We Need the Wild. Enric is an extraordinary enthusiast for nature and a practical person who has personally led important work to save large amounts of the ocean through his Pristine Seas initiative, which we discuss in this podcast. For people who are committed to building back a better world, there could be no better practical guide to some of the challenges of nature of which there are many: preserving our climate, preserving our planet in a healthy way, than Enric Sala. We ask why we do need the wild and many of the calls for action that he makes in the book.
