SeaWorld has been a lightning rod for controversy in recent years, and no one knows that better than John Hargrove. On this week's episode of the Inquiring Minds podcast, Hargrove—a former SeaWorld animal trainer—recounts his experiences working with orcas in captivity. From heavily medicated killer whales to the tragic death of his colleague, Hargrove paints a picture of an entertainment company in crisis. SeaWorld, a nationwide chain of parks well known for its displays of marine animals, purports to blend "imagination with nature" and enable visitors to "explore, inspire and act." It's perhaps most famous for its orcas.
