@farmerman,
I knew a gent in New Mexico who worked in Albequerque as a handyman in the day time, and did the heavy farm labor at home at night. In the daytime, his wife and oldest daughter kept the "truck garden." Much as was the case at home in my childhood, they produced nearly all the vegetables they ate and much of the fruit. When he took to his house, his wife and oldest daugher were making ketchup and stewed tomatoes--from the piles of bushel baskets of tomatoes they had picked that day and the day before.
He had three milch cows, and about 20 steers. These animals were all grazed on BLM land, which was just down the ridge from him. It is pretty common in the west for people to get a permit (for a pittance) to graze on BLM land. The cows produced the milk for the children, and even some surplus to trade to the neighbors. His wife kept chickens for the egg money and their own consumption. The steers were cash on the hoof. If he needed some cash, he could sell of a steer or two. About his only cost was for the bull to service his cows.
Anything beyond an example like his is industrial farming, no matter what people chose to call it. He said as much himself, and said he wouldn't bother for any other reason than to feed his family.
It's just isn't worth it to farm large tracts of land for anything other than a monoculture--and in the southwest, you're not going to have enough land to graze cattle for slaughter. There, feed lots are the only thing that makes sense for livestock production. On our piece of land north of Santa Fe, we boarded horses for the local Indians (no longer allowed to steal horses from the white boys, they'd steal them from one another--those who valued their horses often boarded them). We figured we needed about ten acres on the lower fields (we were above 6000 feet, with the lower fields between 5500 and 6000 feet) and about 15 acres on the home farm--per animal. The Hollywood image of cattle grazing out on the range just don't work no more.
There's more than six billion people on this planet. They're not going to get fed without industrial farming techniques. It makes no odds between livestock production and the production of grain, vegetables or fruit, either. Every objection which can be raised about the "waste" of livestock production can be countered with the truth about erosion and chemical run-off.
Which is why, i suspect, that those opposed to the eating of meat try to make it about morality.
