A Companion to American Environmental History gathers together a comprehensive collection of over 30 essays that examine the evolving and diverse field of American environmental history, and not only presents a state-of-the-field as it stands, but also expands the current scholarship. With contributions from the founders of this unique branch of history, and the work of innovative young scholars, this Companion presents a bold vision for the future of environmental history, as well as a critical appreciation of its growth and development. The essays in this volume are presented in five parts, covering a diverse set of topics that range from American Indian environmental relations, oceans, and food, to borders, culture, and identity. Combining a complete historiography with the most recent research and trends, the Companion pushes the existing boundaries of the field and encourages new directions of study.
