Accepting for the sake of discussion (but not generally) that hunting is "ethical", hunting is also a privilege. We obviously cannot all eat hunted meat for survival. You've no doubt seen the figures.
The sheer variety of produce we currently experience is also an unsustainable privilege.
Eating something with palm oil is also a privilege, one that destroys natural habitats and leads to excess carbon being released to the atmosphere.
I'm not trying to equivocate the two, but the moral justification is similar.
I don't actually think intent is really important to the moral equation. A species going extinct because of over hunting, and a species going extinct because of habitat destruction are pretty morally equivalent to me.
Is that not the same reasoning people use to validate hunting?
This is getting closer to the ethical imperative question I asked. So it seems that the ethical dilemma is based on preserving as much life as possible?
If so, would it be more ethical to eat the insect as a protein source rather than the soy beans they are feeding upon? If the insects as you say are going to be destroyed during the harvest, would it not be morally justified to gather and eat the insects before or after?
My point isn't to be pedantic or actually implement anything we've talked about. I'm just pointing out the internal contradictions that occur in veganism. Not to try and sway anyone's life choices, but to allow for people to understand that it's logically imperfect, and to not let perfection be the enemy of good.
