   What if, one day, something essential to our world suddenly vanished? No warning. No explanation. Just gone. What happens next? Lees meer

   Life Without is a roundtable-style podcast that explores this fascinating and thought-provoking question with insight, evidence-based assumptions and a range of perspectives. Hosted by Alan Davies, each episode brings together 2 guests, scientists, psychologists, economists, sociologists and journalists to discuss the unexpected consequences of losing something vital to our world.

   Each episode starts with a bold, imaginative question: What would happen if something fundamental—like the moon, salt, sleep, or even something as random as rats—suddenly disappeared from the world? What’s the immediate fallout? How does society cope? And how long would it take before things started unravelling?
