"We cannot just do whatever we want with them. ... Certainly, a sort of industrial use of creatures, so that geese are fed in such a way as to produce as large a liver as possible, or hens live so packed together that they become just caricatures of birds, this degrading of living creatures to a commodity seems to me in fact to contradict the relationship of mutuality that comes across in the Bible." -Pope Benedict XVI (current Pope)

"We consume the carcasses of creatures of like appetites, passions and organs as our own, and fill the slaughterhouses daily with screams of pain and fear." -Robert Louis Stevenson
