Rewilding revisited

I'd like to redirect attention to a post I made back in July about Pleistocene Rewilding of North America. In it I offer my opinion that this is a bad idea. Recently, a reader has brought a good discussion to the table and I'd like to see if I can open it up even more. Please jump in with us.

I'd hate to have a discussion that I think could be interesting, educational, and useful be buried under months of newer posts.
