Lets say I agree with the harvesting of foetus or baby parts for a moment, then surely no money should be made out of it? Provided that there is consent from the parent, the parts should be made freely available for medical use or scientific research and nothing else. If these companies need to make money on this, it should be billed on the customer as part of the storage or disposal costs. This idea of selling body parts, sounds like they are looking for the highest bidder, irrespective of what they intend to do with these parts. Feel free to correct me if I am wrong on that last point.
This whole thing just sounds completely unethical and corrupt, regardless of your position on abortion.
