Throughout human history, the rate of world population growth overall has been outpaced by the rate of urban population growth. Right now, more the half the world's population lives in cities, and that proportion will only increase in the next fifty years. Rapid urban growth accelerates the exchange of ideas, the expansion of social networks, and the diversity of human interactions that accompany globalization. The present century is therefore the crucial phase, when the world's increasing interconnectedness may give rise to innovation and collaboration or intensify conflict and environmental disaster. Bringing together scholars of anthropology and social science as well as law and medicine, Globalization: The Crucial Phase presents a holistic and comprehensive understanding of the way the world is changing. The contributors reveal the changing scale of social, economic, and financial diversity, examine the impact of globalization on the environment, health, and nutrition; and consider the initiatives to address the social problems and opportunities that arise from global migration. Collectively, these diverse interdisciplinary perspectives provide an introduction to vital research and policy initiatives in a period that will bring great challenges but also great potential.
