What is the largest living land carnivore?

Dorothy would have been absolutely terrified if she'd run into a polar bear instead of that Cowardly Lion. While the "Wizard of Oz" lion was all bluster and no bite, a polar bear is a 1,500-pound killing machine that can smell a seal from 20 miles away and has zero fear of humans. The polar bear's paws alone are 12 inches across, perfect for both swimming through icy waters and delivering devastating swipes. Their bite force measures around 1,200 pounds per square inch, which means they could crush a bowling ball without breaking a sweat. And unlike other bears that snack on berries, polar bears are only eating kelp in emergencies, otherwise they're 100% pure meat lovers.
