³ While the assumption that we ought to minimize harm is usually implicit in harm-based arguments for veganism, sometimes it is explicit. For instance, Michael Allen Fox claims that “one of the guiding ideals of ecologically informed thinking is that we ought to minimize the harmful impact of our lives . . . on the biosphere” and that this principle of “minimizing harm . . . certainly seems to be about as basic a moral principle as can be imagined” (Vegetarianism and Planetary Health, Ethics and the Environment, 5 (2000), 163–74 (p. 166).

¹⁴ Another reply is skeptical and claims that one does not act wrongly by participating in a collectively harmful practice when one's participation does not make a difference.

¹⁵ This first horn of the dilemma may be seen as a sort of demandingness objection, so that part of the contribution of this article is to point out that this popular and influential argument that veganism is obligatory has to confront this well-known objection.

¹⁷ Mark Budolfson is the first philosopher (of whom I am aware) to give serious consideration to the human worker harm associated with various vegan staples.

²⁵ Working as a professor (rather than in social services, for example) seems like a failure to benefit rather than a harm. Yet, some have argued that some failures to benefit are indeed harms (Feit, Neil, Harming by Failing to Benefit, Ethical Theory and Moral Practice, 22 (2019), 809–23CrossRefGoogle Scholar). Moreover, philosophers employing the harm minimization argument for veganism often treat failures to benefit as on a par with harms, for example, in failing to use agricultural land more efficiently by producing more food to benefit humans rather than food for animals that humans then consume. Space precludes exploring these and other complications.

²⁶ Thanks to Bob Fischer for this point and this way of putting it.

²⁷ Mark Budolfson also rejects harm minimization arguments (though for different reasons) and introduces the idea of a harm budget. See Budolfson, Consumer Ethics, p. 167. Budolfson's work emphasizes the self-defeat of veganic harm minimization reasoning in support of a veganic diet, because a careful omnivorous diet has a lower harm footprint than typical vegan diet. By contrast, my emphasis is on the overgeneralization of harm minimization to other modern lifestyle practices more generally.

²⁹ If we continue to the next generation, one will be 50% responsible for one's child's 50% responsibility for her child's 50% responsibility for 1.7 children, or (0.5)(0.5)(0.85). A little mathematics shows that if we continue indefinitely, the total number of humans one is responsible for producing by having just one child is (0.5) + (0.85)((0.5) + (0.5)² +  (0.5)³ + . . .) = (0.5) + (0.85)(1) = 1.35 humans.

³⁰ Thanks to Bob Fischer for helping me see this point about the size of one's harm budget and for raising the objection immediately following.

³¹ I said in 3.2 that my argument here does not depend on any assumptions about allocating the harm of procreation, but here I am allocating the harm of a person's child to the parent, which may not be warranted if my response to the objection there does not succeed. But I need not allocate all of the harm of a person's child to the parent here. The reasoning here will go through even if we only allocate to the parent the harm footprint of the child until the child reaches the age of majority, say.

³² An anonymous referee raised this objection, using many of these same words.

³³ Again, thanks to an anonymous referee for this objection.

³⁴ Thanks to Bob Fischer, Doug Portmore, Travis Timmerman, and anonymous referees for helpful written feedback and to Lynne Dickson Bruckner and Andrew Fenton for discussion.
