They're omnivores, like other bears. Nobody posts Youtube videos of them eating berries, digging up ant mounds, or licking moths off the bottom of loose shale because it's just not that dramatic, but that's where they tend to get the bulk of their calories from. They will eat pretty much anything they can get their paws on though, especially in the months leading up to hibernation, where their life depends on them building up enough fat reserves to survive the winter. Calves and the injured especially are textbook examples of opportunistic predation - hunt what's easy to catch if the opportunity presents itself. But like humans in survival situation, hunting can easily become a net loss in calories, so that you'd be better off going hungry unless they prey is easy to catch.

Bison once roamed over vast stretches of the country now occupied by farms and cities. Make up your mind, people: is man killing off all the large animals or promoting too many animals?

An estimated 20 to 30 million bison once dominated the North American landscape from the Appalachians to the Rockies, from the Gulf Coast to Alaska. - http://www.defenders.org/bison/basic-facts

Cattle inventory (as of Jan 1, 2015): 89.9 million, up 1% from Jan. 2014. - See more at: http://www.beefusa.org/beefind...

3000 is a bit low, that woiuld be 100 families/tribes with roughly 30 members.
But you are right, the population was very low. Some estimate around -10,000 (before christs birth) the population on the whole planet reached 1,000,000. Some other researchers believe it was more in the 4 - 10 millions range.
OTOH some researchers estimate around -70,000 (BC) the total human population was only 25,000 - 30,000.
I find that a bit low, but who knows. In our days with so many species at the edge of extinction we can hardly get a good idea how big a natural population of any kind is.
E.g. according to this http://www.defenders.org/african-lion/basic-facts ca. 21,000 lions live right now in africa.
OTOH zebras (http://www.defenders.org/zebra/basic-facts) are roughly 750,000. No idea how ancient humans would fit into that picture :D

Without religious fanatics how do you feed the lions ?

Hmmm... perhaps there's a problem with the religious fanatic population. Man, you try to eliminate one pest and the whole ecosystem gets messed up.

The possibility of Marine effect is quite real. Past Navy experiments have had serious deleterious effects on marine life.

As to why, because whales, dolphins et al. are intelligent, endangered creatures. It doesn't mean you give up everything (or even that you give up this technology) to protect them, but it sure as hell means you consider the ramifications and at least look for alternative methods that don't kill some of the most advanced creatures on this planet.

Unfortunately, you can't enclose campaign contributions in emails, so they won't have any effect.

I'm not bullshitting you. I'm a cabinetmaker who lives a mile from one of the largest timber yards in Europe and they've got 1000s of feet of stuff thats marked-up as mahogany - African or Brazilian. No bigleaf or "real" mahogany (Swietenia macrophylla) as it's endangered.

Some high end cabinetmakers (ie. by Royal Appointment) hold private stocks of it but mere mortals like me can't get hold of it. Things might be different in the US.
