John Kinder is the director of American studies and a professor of history at Oklahoma State University. And he is an author. His most recent book is called World War Zoos: Humans and Other Animals in the Deadliest Conflict of the Modern Age.

John's book tells a story most of us have never heard: what happened to the world's zoos—and the animals inside them—during World War II. It's a sweeping, deeply researched look at how zoos became sites of propaganda, patriotism, and survival, often at the expense of the animals themselves.

But World War Zoos isn't just about the past. It's also a mirror, showing how many of the ethical blind spots that existed during wartime remain with us today. In an age of climate crisis and mass extinction, this conversation asks: what do zoos really stand for—and who are they really serving?
