 The “intentionally or otherwise” is important to some. While these harms are foreseen consequences of farming, they are unintended. To some, that animals are harmed but not intentionally harmed in producing corn in Iowa helps to make those harms permissible (see entry on  doctrine of double effect).  Pigs farmed in Iowa, by contrast, are intentionally killed. Chickens and cows, too. (Are any intentionally hurt? Not typically. Farming is not sadistic.)
