One of the world's most influential philosophers here considers the ethical issues surrounding globalization. Peter Singer discusses climate change, the role of the World Trade Organization, human rights and humanitarian intervention, and foreign aid, showing how a global ethic rather than a nationalistic approach can provide illuminating answers to important problems. The book encompasses four main global issues: climate change, the role of the World Trade Organization, human rights and humanitarian intervention, and foreign aid. Singer addresses each vital issue from an ethical perspective and offers alternatives to the state-centric approach that characterizes international theory and relations today. Posing a bold challenge to narrow or nationalistic views, Singer presents a realistic, new way of looking at contemporary global issues-through a prism of ethics.
