Human population is a problem—tackling it through education isn’t.

We need to slow our global fertility rate to 1.5 children per woman if we’re to lower our population to a sustainable level of around 3 billion. That decline is already happening in many post-industrial nations, to the chagrin and panic of their leaders. However, many cultures around the world still prize large families. But in a world of increasingly scarce resources like water, limiting family sizes remains the main driver of some campaigners, including Bill Ryerson.

Bill is an ecologist and founder of the Population Media Center, an initiative which creates mainstream entertainment in many nations around the world, pushing the needle on cultural practices to drive behaviour change on population and even gender violence. PMC produces telenovelas and radionovelas which have seen fertility rates decline in nations they’ve been shown.

Bill and I spend the first half of the episode talking about the population problem, the policy problems, the history of population growth. He then introduces the concept of the demographic dividend, which showed that small families actually lead to economic growth, before explaining the successes and heartwarming stories of the work PMC has done around the world.
