Those animals lived the life you describe. Pampered, taken care of, room to roam, and then swiftly killed because fear sours the meat. They’d kill maybe one cow per year, 2 or 3 pigs. Many chickens.
An 800kg cow produces ridiculous amounts of meat. They’d give it away to their entire extended family because no way they’d eat it all in a year.
But meat you buy in a supermarket comes from factories. Their living conditions are the absolute minimum you can get away with to keep the animal healthy enough to sell its meat. Ridiculous things like keeping chickens in cages then throwing them out in the sun for a week so you can get that “pasture raised” label. At that point they’re too weak to even walk around because their muscles didn’t develop enough and their genetic mutants with oversized breasts.
that shit ain’t cool and we should do what we can to get better laws
