It's so much easier just to blame it on the "Hunter", particular if you are anti hunting or anti gun. Much the same situation existed with the "Buffalo" (Bison). The breed has of course survived & is around in good numbers. Of course modern habitat will never as long as it exists allow them to reach numbers anywhere close to when William Cody was using them to feed the RR workers.
