Final answer:
European governments typically ban the sale of organs, insisting upon altruistic donation. Renewed research is exploring alternatives to human donation, including genetic modification and growing transplantable organs in vitro.
Step-by-step explanation:
Yes, European governments generally prohibit the sale of organs for transplantation and require that organs be obtained only through donation. This approach follows the ethical principle that body parts should not be commodified and aligns with the belief that organ donation should be altruistic. In contrast, there is a growing interest in alternative solutions, such as using genetically modified animals for transplantable organs that do not cause an immune response or growing organs in vitro from an individual's harvested cells to avoid the risk of rejection.
