The history of Homo sapiens is usually told as a story of technology or economics. But there is a more fundamental driver: food. How we hunted and gathered explains our emergence as a new species and our earliest technology; our first food systems, from fire to agriculture, tell where we settled and how civilisations expanded. The quest for food for growing populations drove exploration, colonialism, slavery, even capitalism. A century ago, food was industrialised. Since then, new styles of agriculture and food production have written a new chapter of human history, one that’s driving both climate change and global health crises. Best-selling food authority Mark Bittman offers a panoramic view of the story and explains how we can rescue ourselves from the modern wrong turn.
