No bats in the night sky. In this episode of Life Without, Alan Davies imagines a world where bats suddenly disappear. From tiny insect-eaters to fruit bats, what would humanity miss when these remarkable mammals are gone?

Alan explores the role bats play in controlling insects, pollinating plants and dispersing seeds. He also examines their surprising social lives, their unusual immune systems, and what they might teach us about disease and ageing.

Featuring Professor Kate Jones, Professor of Ecology and Biodiversity at UCL, and Dr Christina Stanley, Associate Professor in Animal Behaviour and Welfare at the University of Chester.

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

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?

What would happen to the world if the USA disappears? In this episode of Life Without, Alan Davies explores a planet earth without the land mass of North America. How would opening up the Atlantic impact us in the UK and what would the disappearance of North American produce and people mean for the rest of the world?

This episode features Dr. Anjana Khatwa an award winning Earth Scientist and author, and Tori Tsui, a climate justice activist, author, and mental health advocate.
