The book suggests models of new world organizations that will be necessary to achieve the elimination of global poverty, injustice, war, and environmental imbalance by the end of the 20th century. The book was developed by the World Order Models Project (WOMP), an international group of researchers and scholars established in 1968 to explore alternative futures. The book proposes a framework for a reformed and integrated world polity, or political unit. It is based on (1) a time frame to be reached by the 1990s, (2) an understanding of present political realities, and (3) a transition strategy for converting present political and value orientations to required future forms. Chapter one explains the values basic to global change, interrelationships among values, acceleration of values change, and the need for centralized guidance. Present trends in world society are explored in chapter two, including population, war systems, ecological pressures, and issues of technological innovation. Chapters three and four suggest models for world order based on state, regional, and world nexuses of power; and propose world systems for security, economics, human development, and ecological balance. Chapter five discusses problems and procedures of the transition to a world polity, stressing minimization of violence and maximization of human well being. Chapters six and seven examine selected aspects of a world economy and America's stake in global reform. (AV)
