The Worst Mistake in the History of the Human Race Jared Diamond Jared Diamond Turn and Talk – Turn and Talk – Would you rather live in a farming community or a hunter-gatherer community. Explain your answer.

Health Concerns First, hunter-gatherers enjoyed a varied diet, while early farmers obtained most of their food from one or a few starchy crops. The farmers gained cheap calories at the cost of poor nutrition. Second, because of dependence on a limited number of crops, farmers ran the risk of starvation if one crop failed. Finally, the mere fact that agriculture encouraged people to clump together in crowded societies, many of which then carried on trade with other crowded societies, led to the spread of parasites and infectious disease.

Class Concerns Hunter-gatherers have little or no stored food, and no concentrated food sources, like an orchard or a herd of cows: they live off the wild plants and animals they obtain each day. Therefore, there can be no kings, no class of social parasites who grow fat on food seized from others. Only in a farming population could a healthy, nonproducing elite set itself above the disease- ridden masses.

Gender Concerns Freed from the need to transport their babies during a nomadic existence, and under pressure to produce more hands to till the fields, farming women tended to have more frequent pregnancies than their hunter-gatherer counterparts-- with consequent drains on their health. Women in agricultural societies were sometimes made beasts of burden.
