The alleged chronic shortage of human organs has led some researchers and federal health officials in the US and elsewhere to consider using organs from animals such as pigs and nonhuman primates. Xenotransplantation, attempted since 1905, is marred by a history of failures and intense human and animal suffering. But the prospect of commercializing the technology has created huge financial incentives for biotechnology and pharmaceutical companies who have invested hundreds of millions of dollars in xenotransplantation. The desire to gain a return on such large investments has led many companies to make exaggerated claims about the alleged merits of the technology. CRT believes that these claims are baseless and that, in fact, the technology is dangerous, expensive, inhumane, and unnecessary, and should therefore be banned.
