One of the primary ways we encounter animals is as a food source. The dominant system of animal agriculture is “factory farming,” which is designed to produce the greatest amount of meat at the lowest possible cost. Factory farming is grossly inefficient from an ecological point of view, imposes enormous suffering on animals, and damages both humans and the environment. “Conscientious omnivores” reject factory farming but defend painlessly killing animals for food. Some defend hunting because they think it promotes other important values as well. These arguments are rejected by vegetarians and vegans, but they remind us that concerns about animals exist against the background of other values, including those that relate to the broader value of nature.
