What has most recently became known in some circles as “Thanos Theory”, many people have wondered, especially in times of serious concerns about climate change and the scarcity of resources just how long this planet can support us…especially as the world’s population is about to eclipse 8 billion people!!! Is this too many? What about estimates of 10 billion by the year 2050?

Is wiping out half the population at the snap of a finger the only way to save everyone else? Some people believe Thanos might have been onto something. There’s got to be another way, no? We are joined by the man who literally started the conversation on overpopulation with his seminal book “The Population Bomb” in 1968!

Dr. Paul Ehrlich helps us break down “how many is too many” and whether the problem might not be “how many” at all, but instead “how we live”.
