Book excerpt: The quest for resources, from farmland to gold to oil, has shaped much of U.S. history. Ensuing competition for these resources has had a tangible effect on both American geography and the environment. This book shows how American communities formed over time in response to environmental factors and how policy, culture, and day-to-day life in the United States is a response to the land itself. Also included is a look at modern debates over the best way to protect the environment while encouraging innovation, including the role of the EPA and other government organizations in regulation.
