On the side note, it's a different subject matter but life consumes other life, this happens on every level from bacteria to mammals. I also don't get the fixation on preventing suffering so much (a little I get it). Life entails suffering, this gets philosophical but aiming at a life with no suffering at all amounts to not being alive. Farm animals are necessary for humans to grow into a civilization size species. We could go back before farming but that would mean billions of people will not exist. I guess pick which evil you want, less humans or animals being domesticated and consumed. (disclaimer, I still think mass farming is really bad and should be solved by responsible consumption and less population).
