Bioethics is the philosophical study of the ethical controversies brought about by advances in biology and medicine. Bioethicists are concerned with the ethical questions that arise in the relationships among life sciences, biotechnology, medicine, politics, law, philosophy, and theology. This book presents research in the expansive field of bioethics including biomedical ethics in obstetrics, ethical decision making in the health care system, the feasibility of using human oocytes for stem cell research, as well as mandatory circumcision in Sub-Saharan Africa to prevent HIV and AIDS and environmental ethics to preserve the world for future generations.
