Polar bears are not naturally inclined to eat dolphins, but territory shrinkage and food scarcity – combined with the fact that dolphins themselves have had to move farther north as a result of rising temperatures – has recently led them to start doing so for the first time in recorded history. The world’s climate has been altered by human activities, namely our industries that spew greenhouse gases into the atmosphere. In an effort to adapt to a changing environment, animals are changing their normal migration patterns and, as in the case of this polar bear, finding new sources of food to sustain themselves.
