Book excerpt: What can be done about the poor state of global health? How are global health challenges intimately linked to the global political economy and to issues of social justice? What are our responsibilities and how can we improve global health? Global Health and Global Health Ethics addresses these questions from the perspective of a range of disciplines, including medicine, philosophy and the social sciences. Topics covered range from infectious diseases, climate change and the environment to trade, foreign aid, food security and biotechnology. Each chapter identifies the ways in which we exacerbate poor global health and discusses what we should do to remedy the factors identified. Together, they contribute to a deeper understanding of the challenges we face, and propose new national and global policies. Offering a wealth of empirical data and both practical and theoretical guidance, this is a key resource for bioethicists, public health practitioners and philosophers.
