The world is changing rapidly and there are increasing calls for international and legal responses. Social changes in areas such as globalization, development, demography, democratization and technology are growing in importance for both citizens and states. Over time this will be reflected in international law and organizational structures, which will have more prominence in governmental functions. In this sense the future of international law is global government. This book draws together the theoretical and practical aspects of international cooperation needs and legal responses in critical areas of global concern and predicts that a more extensive, powerful and varied international legal system will be needed to cope with future opportunities and challenges.
