“To ensure that the pigs can’t run away, farmers in northern New Guinea slice off a chunk of each pig’s nose. This causes severe pain whenever the pig tries to sniff. Since the pigs cannot find food or even find their way around without sniffing, this mutilation makes them completely dependent on their human owners. In another area of New Guinea, it has been customary to gouge out pigs’ eyes, so that they cannot even see where they’re going.7.”
