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.
