Latin America's pursuit of growth and stability is impeded and threatened less by economic and political factors than by resource and environmental mismanagement and by population pressures, according to the contributors to this volume, who urge firm backing from the U.S. in the solution of such transnational challenges. The emphasis is on the Caribbean nations, the northern rim of South America, and Brazil, although several essays are more broadly based, including one on the Alliance for Progress in retrospect.
