pigs are mostly fed crop seconds or other waste product. it’s just not true that we are growing food exclusively for pigs.
the soybean meal is literally the byproduct of pressing soybeans for oil.
Byproduct does not equal waste product. Plastic is a byproduct, so is gasoline. Your conflating the ideas.
Yes, although I suspect we’d actually make less soy oil without the demand for feed. I’m honestly not even sure what it’s used for; most of the vegetable oils on sale where I live are different.
The corn case is pretty unambiguous. DDGS is a byproduct, white grease is probably a byproduct (maybe of pigs, which is “fun”), the rest looks purpose-made but isn’t relevant here.
you don’t feed pigs corn that you could sell to humans. there is a reason it ended up in the barnyard instead of the grocery store.
Yeah, you specifically plant feed corn, instead of grocery-type corn. Also why stealing corn cobs off the roadside can backfire.
