An informal sequel to the award-winning The Land That Could Be: Environmentalism and Democracy in the Twenty-First Century, A Republic of Trees is the latest installment in William Shutkin's on-going quest to align natural and human-made systems into one unified, bold and sustainable model for social and economic development. The book invites us to imagine a political order in which society and nature are seen as interdependent, as sustaining each other in a new republic, a Republic of Trees.
