Most scarcities that underpin health disparities within and among countries are not natural; rather, they result from policy choices and the operation of social institutions. Using examples from the United States of America: the Chicago heat wave and hurricane Katrina, this paper develops “denaturalizing scarcity” as a strategy for enquiry to inform public-health ethics in an interconnected world. It first describes some of the resource scarcities that are of greatest concern from a public-health perspective, and then outlines two (not mutually exclusive) lines of ethical reasoning that demonstrate their importance. One of these involves the multiple relationships that link rich and poor across national borders in today’s interconnected world. The paper then briefly describes ways in which globalization and the associated institutions are linked to health-threatening scarcities. The paper concludes that denaturalizing scarcity represents a valuable alternative to mainstream health ethics, directing our attention instead to why some settings are “resource poor” and others are not.
