IASTATE -- In an opinion circulated since 1987, the well-renowned theorist Jared Diamond argues that agriculture is the worst mistake made in the history of the human race. His essay suggests that we should have remained as hunter-gatherers. The thought has gained social currency on the back of arguments against the European Common Agricultural Policy and remains very relevant in Ireland's goal of accommodating policies that keep the country awash with green tillage.
Besides malnutrition, starvation, and epidemic diseases, farming helped bring another curse upon humanity: deep class divisions. 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, non-producing élite set itself above the disease-ridden masses. Skeletons from Greek tombs at Mycenae c. 1500 B. C. suggest that royals enjoyed a better diet than commoners, since the royal skeletons were two or three inches taller and had better teeth (on the average, one instead of six cavities or missing teeth). Among Chilean mummies from c. A. D. 1000, the élite were distinguished not only by ornaments and gold hair clips but also by a fourfold lower rate of bone lesions caused by disease.
Similar contrasts in nutrition and health persist on a global scale today. To people in rich countries like the U. S., it sounds ridiculous to extol the virtues of hunting and gathering. But Americans are an élite, dependent on oil and minerals that must often be iimproted from countries with poorer health and nutrition. If one could choose between being a peasant farmer in Ethiopia or a bushman gatherer in the Kalahari, which do you think would be the better choice?
Farming may have encouraged inequality between the sexes, as well. 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. Among the Chilean mummies for example, more women than men had bone lesions from infectious disease.
