PBS had a show on about the Grizzly bears yesterday.  Basically, all the efforts to safe them and bring them back from the edge of extinction is just a big old waste of time.  Why? Well, the bears have three primary food supplies if they stay in the wild (away from people). One is fish. The fish they eat are being outpaced by an introduced fish, and alien species from the great lakes that is displacing the fish they normally eat. Well, maybe they could just adapt to this new fish? I don't know. Second, they stock up on nectar filled moths in the summer. They do this in the high country. But the flowers that moths get the nectar from are in danger of being overrun with trees because of the change in climate. Also the moths are at risk from pesticides, but that's nothing new. These are army worm moths by the way. They destroy lawns as larva if they are the same as the ones around here.  Lastly is the pine trees. The bears eat a certain kind of pine nut, and the trees they get them from are now being destroyed by (you guessed it) a disease or insect, or whatever.  These nuts are so important in their diet (and many other animals) that it actually influences the number of cubs born the next year.  And if that isn't enough, the bears were taken off the endangered species list, so some places are now hunting them. 
Actually I can see the last thing, taking them off the list and listing them as 'threatened' rather than endangered, because they have made quite a come back. And there does need to be a balance where people can live and work without being eaten by bears.  But humans generally don't seem able to control themselves, or manage things well when given the chance to go out and kill.  But it's late and I cant think or type so I'll stop now. Hibernation seems like a good thing.
