| > Land being able to grow some kind of plant matter does not mean that the land is suitable for growing plants humans will eat. I don't agree. Ground that can grow animal food pretty much always can grow a human food. I know of no exception (particularly for high production foods). About the only exception I can think of is undeveloped grazing land in the mountains. However, that's such a small percentage of the food that goes into feeding livestock that it's hardly worth mentioning. Most of our meats don't come from animals living on mountain ranges, that's too expensive. It takes ~2 acres to pasture a single cow if you don't actively farm that pasture. On the flip side, that same 2 acres if farmed can easily feed about ~2 cows. In other words, you cut your land requirements in half if you don't pasture your cows. > The plants animals eat are easy to process mechanically at huge scale. The plants humans eat, not so much. Humans do require a bit more processing of their foods than animals do, but not much and not enough to introduce any sort of scaling problem. Certainly not more costly than meat processing. Most meat processing requires manual interaction which is super expensive. On the flip side, plant based processing is pretty much completely automated. About the only part that isn't 100% automated is transport (and usually harvesting, though that's changing fast). As with everything, manual processes are the most expensive part of anything because humans cost a lot of money. Meat is a solution to the energy density problem. Meats are high in protein and energy which makes for a good winter food for farmers (so long as you can keep it cold, it will last a long time). |
It's also an ecological mess. Cows aren't native to North American mountain ranges and are tremendously destructive. Also, native predators get hunted to protect the non-native cattle which causes an even bigger environmental mess.

Yes? But it's a terrible practice. The cows end up piled atop each other in big barns waste deep in their own shit. Then they end up draining the barns into massive shit ponds which have to be filtered with large RO systems. The densely packed cattle are in such poor health they are over-medicated to prevent disease and that medication ends up in the food chain.
Pasture raised beef is just much better. I'd just as soon we limited how much total beef was raised and did it in pastures rather than corn-fed barn raised beef. Its more humane and while it's not been proven, the large amounts of antibiotics in barn raised beef is almost certain to have effects on humans who eat that beef.
