Bill Ryerson, an expert on human population and the need to slow global fertility rates, discusses the population problem, policy problems, and history of population growth. The podcast also explores the success of Population Media Center's use of telenovelas and radionovelas to drive behavior change on population and gender violence. It touches on cultural perspectives on family size, the importance of family planning and economic growth through small family norms, and the urgent need for renewable energy and preserving the planet's habitability.
