Well, I wasn't meaning to make the claim that the worst natural fiber is environmentally better than the best animal fiber. I definitely think sustainably farmed natural fibers are still better than using animals, although I am not an expert on the subject. Also not denying that wool clearly is a pretty good material in some ways.

Really, I'm coming at this from an ethical persplective - I don't think we should have livestock at all, and I don't think we should continue to breed domesticated sheep. Also, are they just being sheared, or also killed? (including the children)

And from a land use perspective, it could either be completely natural environment, or usable human space

I think that this sort of thing is way way better than the status quo, but it isn't quite what I would consider utopia
