Kris and her late husband, Doug Tompkins, have been instrumental in the creation of 13 national parks in Chile and Argentina, conserving over 14 million acres of land. Dr Dolors Armenteras is one of the world’s leading scientists on forest fires. Originally from Spain, she now works with the National University of Colombia. She spent the last 20 years fighting to save the country’s Amazon forest, and against misogyny in science. Produced by Alice Gioia.
