This exciting new reader in environmental history provides a framework for understanding the relations between ecosystems and world-systems over time. Alf Hornborg, J. R. Mc Neill, and Joan Martinez-Alier have brought together a group of the prominent social scientists, historians, and geographical scientists to provide a historical overview of the ecological dimension of global economic processes. Readers are challenged to integrate studies of the Earth-system with studies of the world-system, and to reconceptualize the relations between human beings and their environment, as well as the challenges of global sustainability.
