One objection to xenotransplantation is that it will require the large-scale breeding, raising and killing of genetically modified pigs. The pigs will need to be raised in designated pathogen-free facilities and undergo a range of medical tests before having their organs removed and being euthanised. As a result, they will have significantly shortened life expectancies, will experience pain and suffering and be subject to a degree of social and environmental deprivation. To minimise the impact of these factors, we propose the (...) following option for consideration—ethically defensible xenotransplantation should entail the use of genetic disenhancementifit becomes possible to do so and if that pain and suffering cannot be eliminated by other means. Despite not being a morally ideal ‘solution’, itismorally better to prevent unavoidable pain until a viable non-animal alternative becomes available. (shrink)

Nonhuman animals are unable to exert any direct control over the functioning of democratic institutions –the decisions of which, nevertheless, have a pervasive impact on their lives. Their interests are therefore likelier to be set back or unfairly discounted, and their choices are more vulnerable to arbitrary interference. Because of this, some authors have suggested that we ought to redesign our political institutions so that they are more responsive to the interests of animals. We argue that this strategy fails to (...) address the root of the problem, which is animals’ lack of robust political agency. We defend that, should it become technologically feasible, we have a pro tanto obligation, derived from the values that underpin democracy, to uplift, or radically enhance, the political agency of nonhuman animals, so that they can better participate in mass democratic politics, express their interests as they see them, self-organise to defend them, and hold their representatives accountable. Finally, we explain how our argument manages to resist the most important objections against animal enhancement and, in some cases, it does so better than alternative proposals based on the value of animal well-being.
