"Agriculture makes life more toilsome and less secure. The more your food comes from agriculture, the harder you have to work. The rate at which hunting and gathering pays off - 1 calorie of work gets you 5 calories of food. By contrast, with farming, 1 calorie of work gets you 2 calories of food. Growing your own food represents the path of greatest resistance, and the more of it you grow, the greater the resistance. But travel to the most inhospitable desert of Australia during the most horrendous drought - and you won’t find a single starving aborigine anywhere. Our agricultural revolution had so little going for it that it’s a wonder it happened at all."
