"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. On climate change, for example, he sees the ethical issue as one that concerns a common global resource - the capacity of the atmosphere to absorb waste gases.

How much of this resource should developed notions appropriate, and how much should be left for developing nations? Regarding the WTO, Singer asks whether the organization allows free trade to override all other values, and he assesses the evidence for and against the view that globalization helps the poor. In his consideration of human rights, the author asks to what extent we can develop global laws protecting human rights and what the criteria for intervention should be when these rights are violated.

Finally, Singer addresses the obligations of the world's rich nations to assist the poor nations."--BOOK JACKET.
