John Lee's, David Fedman's, and Lisa Brady's essays persuasively show the value of studying environmental issues on the Korean peninsula. Each of the essays carefully explains how drives led by individuals and entities, such as the state, engineered nature for human needs, security, and later economic growth. In so doing, they show how these drives simultaneously altered nature and remade institutions, systems, and cultures that influenced people's agency and identity and reshaped forms of consciousness. By judiciously making visible the agents and social forces behind the reconstitution of nature, the essays collectively introduce diverse approaches to the study of environmental issues in Asia and elsewhere. Most of all, they demonstrate that transnational environmental history on the Korean peninsula can no longer be overlooked when dwelling on and debating major historical and theoretical issues in Korean, Asian, and environmental studies.
