Honestly we need to quit pretending that we, as humans, are something special as compared to other omnivorous or carnivorous mammals. OK we have more gray matter comparatively but really that means nothing. Some cultures eat octopus, some eat dogs, some eat cats, some eat cows, and of course some eat humans. And some eat vegetation. Do you honestly think those cultures sit back and question what they are doing and if…
Is your point that the majority of people don't consider their own actions as moral agents so we shouldn't either? If you're browsing this website from a phone or computer you are beyond the clamber of mere survival. You have time for ethical reflection.
