From the origins of "Penn's Woods" to the controversial practice of fracking, Cradle of Conservation provides the first comprehensive study of Pennsylvania's environmental history. The story starts with forester Ralph Brock at the dawn of the conservation era and continues through the eras of energy production using coal, oil, natural gas, and other resources. This project was financed in part by a grant from the Commonwealth of Pennsylvania, the Department of Community and Economic Development.
