This book argues that global bioethics is a necessity because the social, economic and environmental effects of globalization require critical responses. Global bioethics is not a finished product that can simply be applied to solve global problems, but it is the ongoing result of interaction and exchange between local practices and global discourse. It combines recognition of differences and respect for cultural diversity with convergence towards common perspectives and shared values. The book examines the nature of global problems as well as the type of responses that are needed, in order to exemplify the substance of global bioethics. It discusses the ethical frameworks that are available for global discourse and shows how these are transformed into global governance mechanisms and practices.
