They’re called “transplant tourists.” In need of an organ transplant but lacking a donor, they travel to countries where human organs are available for purchase on the black market. The organs they buy are harvested from the poorest of the poor, those who are most desperate for money. Often, after the organs are taken, the promised payments are never made.
Monir Moniruzzaman is an assistant professor in the Department of Anthropology at Michigan State University. He's studied the sales of organs by people trapped in extreme poverty and was invited to the Vatican to participate in a summit on organ trafficking.
