In 1993, a turtle whose shell grew around a discarded plastic 6-pack ring was found in the St. Louis region. She was named Peanut, and she’s become one of the best-known animal ambassadors for litter awareness ever since. We celebrate Peanut’s 40th birthday and talk about her story with her caretaker, Missouri Department of Conservation naturalist Matthew Cavanaugh. Tierra Curry of the Center for Biological Diversity and David Mizejewskiv of the National Wildlife Federation also join the conversation to discuss the power of individual animals’ stories, like Peanut’s, to promote social change.
