Collapsing birthrates have inspired dramas from The Handmaid’s Tale to Children of Men, but it isn’t just science fiction any more. We might not realise it, but we’re living through an epidemic of infertility – and it’s getting worse. How did we get here? What does it mean when humans have fewer babies? And how do we turn it around?     Jude Rogers finds out from world-leading environmental and reproductive epidemiologist Dr Shanna Swan, author of the cheerily-entitled Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development and Imperilling the Future of the Human Race.    • “This is too fast to be merely evolution... This is a worldwide challenge, if not a catastrophe.” – Dr Shanna Swan  • “Chemicals that affect hormones are influencing the decline in birth rates. We’re the guinea pigs… People need to exert pressure on governments to bring in legislation to stop that.” – Dr Shanna Swan    Support us on Patreon: www.patreon.com/bunkercast       Written and presented by Jude Rogers.
