In his new book, "The Red Market: On the Trail of the World's Organ Brokers, Bone Thieves, Blood Farmers, and Child Traffickers", Scott Carney documents a growing trade in human body parts and fluids. These are not voluntarily donated or taken from people after their deaths. They're part of a "free market" solution to the desperate need for transplant organs and other biological materials. Macabre? Yes. Surprising? Not really. Without effective government oversight in India, China and other supplier countries, and with demand and prices high, the trade in pieces of people will continue to grow. So called "free markets" value nothing other than profit. If they are not controlled, if people don't intervene and insist on valuing human life and dignity over mercantile greed, this kind of practice will spread.
