Should we punish the bear when it catches a salmon? The hawk when it snatches a lizard? Certainly this article is well done and has provoked many thoughts, but the bit on the NAP applying to animals could use more explaining. If there was no inter-sentient-species aggression, wouldn't the food chain have capped off at snails and minnows? I understand that vegan diets could be legitimate for the world population, and I find no need to argue the "what about agressing plants" type position because I find that most definitely ridiculous, but where is the line drawn for things like insects? If you could point toward some literature on the subject, it would be greatly appreciated.
