When the Agricultural Revolution happened 12,000 years ago, humans began gathering around areas where crops grew in the wild. They soon began planting more crops and forming more permanent settlements around them.

He also thinks people in farming societies suffered tremendous anxiety about their crops, and they were generally more miserable overall. Harari thinks that all this effort to make life easier—by shifting to farming—ended up making life harder for most of humanity.
