Hippo ranching, a poop vault, and orcas sinking boats

We have so much on our minds that we couldn’t pick one topic for today — we’re going with three! Strap in. First: a failed bill from the 1900s that proposed hippopotamus ranching in the U.S. Then: an initiative to save humanity by storing poop in a vault And finally: orcas teaching each other to sink boats. GUESTS: Dr. Shoshi Parks: freelance writer Dr. Maria Gloria Dominguez-Bello: Professor at Rutgers University and President of The Microbiota Vault Monika Wieland Shields: Co-founder and Director of the Orca Behavior Institute and author of Endangered Orcas: The Story of the Southern Residents Support the show: http://www.wnpr.org/donateSee omnystudio.com/listener for privacy information.
