Least harm: a defense of vegetarianism from Steven Davis's omnivorous proposal

Abstract

In his article, “Least Harm,” Steven Davis argues that the number of animals killed in ruminant-pasture production is less than the number of animals killed in crop production. Davis then concludes the adoption of an omnivorous diet would cause less harm than the adoption of a vegetarian diet. Davis’s argument fails on three counts: first, Davis makes a mathematical error in using total rather than per capita estimates of animals killed; second, he focuses on the number of animals killed in production and ignores the welfare of these animals; and third, he does not count the number of animals who may be prevented from existing. When we correct these errors, Davis’s argument makes a strong case for, rather than against, adopting a vegetarian diet. (edited)
