With the growth of environmentalism as a political movement in the 1960s and 1970s, the natural world also began to find its way into scholarship. The realization of all the ways that modern man was shaping nature, intentionally and unintentionally, drove historians to look at the ways earlier societies had changed their environments as well.
Among the pioneers of the field was William Cronon of the University of Wisconsin. His best-known work focused on the ways that different attitudes about land ownership between Native Americans and European settlers altered the New England landscape, and on how 19th-century Chicago, as it grew up into one of the nationĂ¢??s great cities and trading hubs, reshaped the vast fertile plains around it – reshaping, as well, American attitudes about food and farming.
