## Resource

Cities are usually explained through buildings, infrastructure, policy and planning. Food rarely gets a look-in. Which is strange, because for most of human history, cities existed in the first place because we learned how to feed ourselves at scale. Farming allowed settlement. Settlement allowed specialisation. Specialisation gave us civilisation. Long before zoning codes or masterplans, food decided where cities formed, how power worked, and why empires survived or collapsed. In this episode, I’m joined by architect and writer Carolyn Steel, whose books Hungry City and Sitopia have quietly reshaped how many people think about food and place. Carolyn doesn’t approach food as lifestyle or culture. She treats it as infrastructure. A lens that connects geography, logistics, politics, economics, health and social life in ways that most urban conversations completely miss. We talk about cities as food machines, moving from Rome, Paris and London to Chicago, tracing how grain, rivers, canals, railways and refrigeration shaped very different political and economic outcomes. We explore how technology didn’t just speed food systems up, but fundamentally altered them, separating calories from nutrition and convenience from ritual. A big part of the conversation centres on Carolyn’s idea of exo-evolution : the moment when humans stopped adapting themselves to their environment and instead began redesigning the environment to suit their desires. Cities, it turns out, adapt very quickly. Human biology does not. We also dig into what was lost when markets gave way to supermarkets, how food was deliberately redesigned to remove human interaction, and why eating together remains one of our most overlooked forms of civic infrastructure. This is a conversation about food, but it’s real…
