ABSTRACT
One of the motivating factors for adopting a vegan diet is the belief that it is wrong to inflict unnecessary death on nonhuman animals (hereafter “animals”). Call this the unnecessary death principle. Given that one can have an optimally healthy diet consisting exclusively of plants, 2 the practice of killing animals for their flesh and secretions appears to constitute inflicting unnecessary death on them and is therefore morally impermissible according to the unnecessary death principle. 3
