There is obviously a lot going on in very complicated debate on just how to count fish farm salmon for purposes of the Endangered Species Act. The Bush administration says farmed salmon are the same as wild salmon under the ESA. Some conservationists say that is nuts.
But this just points up the fact that the ESA was never really about animals, it was about habitat, specifically a law used to stop the development of habitats of species deemed to be under threat of extinction. If it is an Endangered Land Act some want, then let's have that debate.
