?? We are not carnivores. We are literally some line between herbivores and omnivores. Carnivores have to kill or they will most likely starve to death. Vegtables and fruits are the natural foods of earth for herbivores and omnivores and some carnivores. You are not killing when you eat plants and fruits. Fruits and vegtables want to be eaten for their seeds to spread. It is not a question of concious vs unconcious. Killing animals when you don't need to is already morally unaccepted in society. Animal life and plant life are completely different. To combine them and act like it is the matter of concious vs unconcious bias is completely wrong. An animal will run till exhaustion to avoid being eaten. A fruit tree is there to be eaten. Plants and fruits don't have a central nervous system where they 'feel' pain. Humans are literally animals. Eat a fruit and plant the seeds and see what happens. Eat an animal and plant the bones and does a new animal come up?
You are killing when you eat plants and fruits. Are you foraging in the woods for these things? Or are you buying them from the supermarket, from an orchard where the farmer killed a thousand acres of native flora and all the fauna dependent on that flora to grow these fruits and nuts fit for shipping across a continent?
Everything has a cost, and we should be conscious of them so we can work on mitigating them, no matter if the cost is to intelligent or unintelligent life. Most of the biomass on earth comes from unintelligent life.
You are still conflating killing animals for food & growing plants/vegtables/grains as if they can be equivocated. These are 2 drastically different things especially when it comes to morality and ethics.
