The world is populated by almost 8 billion people. Is overpopulation actually a problem? As climate change disrupts and destroys the livelihoods of so many of those 8 billion people, how will countries react to the growing need for more welcoming immigration policies? This week, we spoke with Dr. Jennifer Sciubba about her new book 8 Billion and Counting: How Sex, Death, and Migration Shape Our World. Dr. Sciubba is an associate professor in the Department of International Studies at Rhodes College and a Global Fellow with the Environmental Change and Security Program at the Woodrow Wilson Center.
