How much life is killed to feed you daily? Plants are a living organism.
Living in tune with nature is not bad especially when you do not live in a way that espouses "karmic" anything.
You live your way due to "karmic" understanding, they live their way due to "nature" understanding. There is more then one path to enlightenment.
Somehow I think you wouldn't hesitate to kill a "poor" creature in the wild to survive whether for food or defensive reasons.
