Trade has shaped human civilisation for thousands of years. From the copper used in Mesopotamian ploughs to the silicon inside our smartphones, vast networks have evolved to move the materials and products on which modern life depends. Yet much of this system remains invisible, only becoming clear when disruption exposes how fragile and interconnected it really is.

In this episode, host Carl Miller speaks with journalist and bestselling author Ed Conway about the hidden world behind the things we buy. Through the stories of bread, cloth and cars, Ed traces the extraordinary journeys taken by everyday products and reveals the people and supply chains that make them possible. From the Corn Laws to the National Loaf and the fish finger, he shows how trade has shaped what ends up on our shelves and plates.

Why has trade become one of the defining geopolitical issues of our time? What happens when governments intervene in supply chains? And how does the global economy respond when those networks are ruptured? Drawing on economic history and first-hand reporting, Ed explores how trade adapts and reshapes the world around us.
