Why you should listen

Paul Root Wolpe directs the Center for Ethics at Emory University,  where he works on the biggest issues most of us face in our life-long ethical journey: death and dying, new reproductive technologies, and new medical and scientific breakthroughs that are not covered in our traditional ethics (what would the Bible say about growing a human ear on a mouse?).

He's also the chief bioethicist at NASA, where he advises on the medical experiments that happen during space travel.
