David Batstone is an ethics professor at the University of San Francisco and is the founder and president of Not for Sale, an abolitionist organization. He is also a journalist and the president and founder of Right Reality, an international business that engages in social ventures. He is a leader in Central American Mission Partners, a human rights group. As a representative of this group, he met with Bono through Glide Memorial Church during A Conspiracy of Hope, a concert tour in support of Amnesty International. When Mark Juergensmeyer was doing research for his book The New Cold War?: Religious Nationalism Confronts the Secular State, Batstone assisted him in finding primary sources with respect to the Nicaraguan Revolution's Christian supporters. Batstone wrote the book Not for Sale: The Return of the Global Slave Trade - and How We Can Fight It, in which he wrote about human trafficking and how social inequality and poverty make it easy for traffickers to find girls to traffick. Julie Clawson wrote positively of this book, writing that she appreciated Batstone's "audacity in telling story after story of modern-day slavery." [More at Wikipedia]
