The Geopolitics of Global Citizenship
National citizenship has long been associated with connection to particular territory and the obligation to defend "the land of my birth." "Defending the nest" is common to other species as well, who are equally concerned with survival. Political identity has often been related to specified territory; it has also been formed by narratives about how national citizens arrived and developed in their homeland. Increasing numbers of people see the entire globe as their own and humanity's homeland. Threats to the homeland are no longer restricted to foreign armies or terrorists attacking a portion of the globe's surface. Threats to the home that sustains humanity and all life include exhaust pipes and smokestacks. Increasing numbers of people identify themselves as global citizens who have an obligation to defend the globe in ways that can sustain human security from environmental collapse. New long-term histories of the common origins of human ancestors, their relationship to the globe, and their global migration from Africa to the rest of the world have begun to establish new, global identities. Narratives of humanity's common origins and environmental narratives of our common destiny on our small planet bolster the development of global citizenship.
