The cost of world population

On this episode of The Cost of Everything, we take a closer look at the hotly debated topic of population growth.

Many point out, however, that lowered fertility rates put many countries at risk of extinction. Host Christy Ai digs into the topic with lecturer Dr. Heather Alberro.
