"most of the livestock in developed countries is reared in grain-fed CAFOs"

That simply isn't true. It is very, very common in the US. I've not seen a trace of it in Norway: Farmers here seem a bit appalled. From what I understand, at least some aspects of this sort of farming have been outlawed in much of Europe, and Europe is full of so-called "developed countries".
