e number of people that same land can support through subsistence (bare necessities) living. Because of agriculture, a standing armies developed among the stronger societies. b great forests in North Africa were destroyed. c hunter-gatherers were able to buy food from neighbors. d the building of cities was delayed by 1000 years.
