I'm not surprised. I saw a whistle blower at a pig farm showing them grinding up waste food from super markets, packaging and all feeding it to the pigs. They eat all the plastic and junk, we eat them.
Found this on youtube. I grew up around farms, and it looks about right.

Also, classic scene from Snatch:
I see animals as individuals and as people. I grew up on and around family farms (for sustenance, not profit). I'd rather we had less of The Jungle (Upton Sinclair) and more of everyone at least witnessing the butchering of the animals they'll be eating. I wish I'd gotten on a fishing boat at some point when I was younger.
I'm trying out eating three times a week (not a magic number, just what I've settled on for now), and now that I'm used to it I want the food I eat to be the best we have--fresh land greens, less-fresh sea greens, fruits and vegetables, whole grains (oat groats, wheat berries, etc.), local eggs, and definitely-not-local sardines, mackerel, and oysters because I love seafood and my child's pediatrician says the omega-3s are good for a child's brain development (and no, I don't impose this regimen on anyone else in my family--I still make meals and sit down together with my warm salty water). Red meat maybe once a month, maybe. Delicious bacon a few times a year. Mostly chicken, eggs, fish, and butter when I eat animal products. I'm not wasting my eating time with anything sweet or "deliciously processed" because it doesn't feel good afterwards and is not as nutritious as the other stuff (this after half a lifetime of snacking on sweet foods, prepackaged and homemade).
I know fungus can supply some things meat otherwise would, like cyanocobalamin (B12, I think). I like nutritional yeast for that. Feel free to refute and/or add to any of this mostly emotion-based perspective--I'm still learning.
From what I understand fungus does not produce B12, it's only produced by bacteria. It's added to nutritional yeast ... to make it more nutritional. Bacteria in our (and other animals') guts do produce B12, but we tend to need extra B12 nonetheless.
I don't eat meat aside from a bit of fish, but I agree that a little meat in everyone's (especially children) diet would not be a bad thing. It's best not to be puritanical or extreme when it comes to diet. We're omnivores after all.
I have a pet idea that a real paleo diet would include insects and grubs, but not sure if there's much anthropological evidence for that.
Extrapolating one video filmed by a non objective part, in one "farm" as a proof that everybody is doing the same is just lying to yourself. Anybody could feed pigs gross things to videotape it.
It's a brutal industry where profits come down to how cheap you can raise a pound of flesh.
Maybe Moses was told "Be careful with consuming those underground fossil fuels" and, lacking context, he wrote down: "Be careful with eating those underground ancient insects" - which turned into a ban on eating grasshoppers.
Secondly, you're making a huge fallacy. While many Arabs did not read or write at the time (and this wasn't just specific to the Arabs), they were not ignorant or dumb, which you seem to be implying. We have many surviving poems from the pre-Islamic era. They were very smart people, as we know from history.
