Affecting future individuals: Why and when germline genome editing entails a greater moral obligation towards progeny

Procreating in an Overpopulated World: Role Moralities and a Climate Crisis

It is an open question when procreation is justified. Antinatalists argue that bringing a new individual into the world is morally wrong, whereas pronatalists say that creating new life is morally good. In between these positions lie attempts to provide conditions for when taking an anti or pronatal stance is appropriate. This paper is concerned with developing one of these attempts, which can be called qualified pronatalism. Qualified pronatalism typically claims that while procreation can be morally permissible, there are constraints on when it is justified. These constraints often concern whether an individual is motivated to procreate for the right reasons. For instance, if someone is not sufficiently concerned with the child's future welfare, the qualified pronatalist will say that procreation is not justified. Moreover, David Wasserman says that this concern forms a role-based duty. That is, prospective parents have special duties to be concerned for the child's future welfare by virtue of the role they occupy. In this paper, I argue that a proper examination of a prospective parent's role-based duties entails that more is needed to justify procreation. Bringing a new person into the world leaves fewer resources for people who already need them, and the current size of the human population is unsustainable from a planetary point of view. Therefore, even if there is nothing wrong with procreation per se, the external condition of overpopulation, and its ensuing public health issues, plausibly gives rise to a role-based duty that prospective parents must account for when deciding whether to procreate.

Affecting future individuals: Why and when germline genome editing entails a greater moral obligation towards progeny

Assisted reproductive technologies have greatly increased our control over reproductive choices, leading some bioethicists to argue that we face unprecedented moral obligations towards progeny. Several models attempting to balance the principle of procreative autonomy with these obligations have been proposed. The least demanding is the minimal threshold model (MTM), according to which every reproductive choice is permissible, except creating children whose lives will not be worth living. Hence, as long as the future child is likely to have a life worth living, prospective parents may be allowed to use preimplantation genetic diagnosis (PGD) to select embryos with genetic diseases or disabilities. Assuming a consequentialist person-affecting view of morality, this paper investigates whether the MTM is an appropriate tool to guide procreative decisions given the continuous development of reproductive genetic technologies. In particular, I consider germline genome editing (GGE) and I argue that its application in human reproduction, unlike PGD, should be conceived as person-affecting towards future progeny. I claim that even if we assume the plausibility of the MTM within PGD, we are committed to accepting that a greater moral obligation towards progeny should guide procreative decisions if GGE were available. In this case, the MTM should no longer be considered an appropriate instrument to guide procreative choices. Finally, I investigate when we face this greater moral obligation, concluding that it applies only when prospective parents have already engaged in the in vitro fertilization process.
