Comparing the best-grown plant protein with the worst-grown animal protein is a bit disingenuous. I can easily source you an animal carcasse that was 100% pasture-grown and pasture-fed where I know everyone involved in its supply chain, from insemination to distribution. Moreover, that same animal will have been net-positive to its ecossystem through foraging etc etc. It won't be cheap, but health-positive and planet-positive meat exists.
