Erika and Dave dig into the more fascinating aspects of sustainable living - including the joy of living sustainably. It’s all about ending our culture’s love affair with “more,” which is not making us happier and is killing our planet. No half-hearted greenwashing here; we share the brutal and joyful truth! Dave directed the documentary GrowthBusters: Hooked on Growth, which Stanford Biologist Paul Ehrlich declared “could be the most important film ever made.”

In Avengers: Infinity War the villain Thanos wants to solve overpopulation by exterminating half the population of the universe. Whenever overpopulation pops up in the movies, it’s always a villain with an inhumane solution. Dave and Dana discuss whether this helps or harms the cause of achieving a sustainable human population (yes, the world IS overpopulated today, and the forecasts are to add several billion more). Aren’t there humane, noble solutions to overpopulation?

Plus: Are we hardwired to reproduce? Population control, Paul Ehrlich, Thomas Malthus, Dan Brown’s Inferno novel and movie, Soylent Green, ZPG, and Dave’s Top 10 Overpopulation Films also come up. (See links below)
