On a planet with 8 billion people, what’s the argument for an individual doing the right thing if it’s barely a drop in the bucket? Travis Rieder, faculty member at the Johns Hopkins Berman Institute of Bioethics, where he directs the Master of Bioethics degree program. He holds secondary appointments in the departments of Philosophy and Health Policy and Management, as well as the Center for Public Health Advocacy and he joins host Krys Boyd to discuss our everyday challenges and the moral quandaries they put us in, and how to do the decent thing in a global and complex world. His book is “Catastrophe Ethics: How to Choose Well in a World of Tough Choices.”
