Which one would win a fight, a polar bear or a grizzly bear?
The grizzly bear, by all means.
Polar bears are known for their poor sense of smell – but grizzlies have an excellent one. Polar bears also depend heavily on the ice to hunt their prey, which is difficult to do with a changing climate and melting Arctic ice lakes; polar bears now being forced into larger hunting areas where they cannot differentiate between seasonal foods. On the other hand, ursus arctos horribilis can live nearly anywhere. They are fluent in bitter cold and rain and snow – ursus arctos horribilis subsist off prey many small carnivores would not dare go near: fish (salmon), rodents (rabbits) even birds!
