fifty thousand years, right up to the industrial revolution, human civilization was about one thing and one thing only: food. Every culture that existed put most of their time, energy, manpower, and resources into food. Hunting it, gathering it, farming it, ranching it, storing it, distributing it…it was all about food. “Even the Roman Empire. Everyone knows about the emperors, the armies, and the conquests. But what the Romans really invented was a very efficient system of acquiring farmland and transportation of food and water.”
