Monday, the acclaimed naturalist and writer Diane Ackerman talks about the story she uncovered of Jan and Antonina Zabinski, a zookeeper and his wife. The couple ran the Warsaw Zoo during the brutal Nazi occupation of World War II, and they were able to save more than 300 people destined to be exterminated by the Nazis. Ackerman’s book has been made into a film, so we’re rebroadcasting our conversation with her about the role of nature in kindness and savagery. (Rebroadcast)
