Who do you think would win a fight between a grizzy bear and a lion?

If admiring the strength and fighting prowess of animals gets you interested in science or even animal conservation it is a good thing. Black bears are the ones that climb trees, not brown bears. Lions can climb too, but not very well. Not as well as the leopard can, the best feline climber of all the great cats. Grizzlies are the largest up north and as you go southward grizzlies become smaller. A grizzly to the south might weigh only 300 to 500 pounds, and even match for the lion. Northern grizzlies can weigh 800 even 900 pounds or more. An animal like that should be able to beat just one lion no problem.
