From the dust jacket: "Work shapes the lives of all human beings. In fact, 'work' is defined as 'the principal business of one's life.'...HARVESTERS looks at the many occupations associated with the collection and cultivation of food. It presents historical profiles of beekeepers, fishers, whalers, hunters, gardeners and divers, and explains in detail the development of farming from 3000 B.C. to the present. Also of particular interest is its account of the impact machine inventions such as the gasoline-powered tractor and the mechanical milker have had on farming."
Discussed is how and why an occupation came into being; how it has evolved over the ages; what specific tasks are performed; and the social significance of the occupation.
