The books in this series study the ways in which the natural environment and human societies have interacted throughout history and around the world. All human societies have by necessity had a strong relationship with their ecosystems, through behavior that has been variously adapting, exploiting, transcending, destroying, or preserving. A key component of the books in this series is the use of new methods of historical analysis - e.g. ecological - to help explain historical events, cultural patterns, and social organization.
