Ethics of eating meat
In many societies, controversy and debate have arisen over the ethics of eating animals. The most commonly given ethical objection to meat-eating is that, for most people living in the developed world, it is not necessary for their survival or health; hence, it is concluded, slaying animals just because people like the taste of meat is wrong and morally unjustifiable. Ethical vegetarians may also object to the practices underlying the production of meat, or cite concerns about animal welfare, animal rights, environmental ethics, and religious scruples. In response, proponents of meat-eating have adduced various scientific, nutritional, cultural, and religious arguments in support of the practice. Some meat-eaters only object to rearing animals in certain ways, such as in factory farms, or killing them with cruelty; others avoid only certain meats, such as veal or foie gras.
