After a beloved gorilla at the Toronto Zoo named Charles died last month, hundreds of people visited his enclosure to mourn and lay flowers. But did his fellow apes understand that he had died? Did Charles ever contemplate his own mortality? Susana Monsó has long contemplated questions like these as she seeks to understand how animals understand death. The philosopher joins Piya Chattopadhyay to talk about how all kinds of animals relate to mortality... and what we humans might learn from them.

Host Piya Chattopadhyay speaks with Carleton University's Ian Lee about the latest on the Canada post strike and the postal service's future, Dene leader Georges Erasmus reflects on his decades-long fight for Indigenous rights, World Meteorological Organization secretary-general Celeste Saulo talks climate, cash, and the role of meteorology in navigating a warming world, The Sunday Magazine's Peter Mitton unpacks the politics of grievance, and philosopher Susana Monsó examines how animals relate to death.
