Humans are the only animals that have children on purpose, keep in touch (or don't), care about birthdays, waste and lose time, brush their teeth, feel nostalgia, scrub stains, have religions and political parties and laws, wear keepsakes, apologize years after an offense, whisper, fear themselves, interpret dreams, hide their genitalia, shave, bury time capsules, and can choose not to eat something for reasons of conscience. The justifications for eating animals and for not eating them are often identical: we are not them.
Jonathan Safran FoerEating a piece of meat, at its most efficient, we could say is like throwing away six times that amount of food every time you eat it because you're recycling all those calories through it. I know a lot of people who came to this issue not through animal welfare but through wastefulness.
Jonathan Safran FoerEvery factory-farmed animal is, as a practice, treated in ways that would be illegal if it were a dog or a cat.
