Regardless of how one would like to spin it, industrial scale animal production means farming animals with the intent to match market prices or you go out of business. That means the production goes by the minimal animal welfare required by law.
Whether one believes conditions are torturous or not that bad, is beside the point, which is that they wouldn’t even exist if we didn’t spawn them. So what we do is we rip new life into the universe by force for that life to suffer to some degree, its’ life’s only meaning being to be processed for food. There was nothing, now there is. Somehow human kind has decided ethical discussion need not concern animals.
