Overview: As the ice shrinks in the Arctic, polar bears are struggling to survive in a fast melting world. Although classified a marine mammal, the polar bear is not adapted to hunting in the water. And it is certainly no match for the world's greatest aquatic hunter - the killer whale.

DVD Verdict: This is a beautiful documentary about the Arctic. Well done cinematography in cold climates of melting snow and glaciers in vast open untouched habitats by humans except few Inuit and a wildlife that has been changing course since 2002 due to the climate change and melting snow.

When the only barrier ice breaks and melts in the Arctic, the most ruthless hunting groups in the oceans, armed with the second largest brain in marine mammals, killer whales aka orcas travel some 2,500 miles in eight weeks, to hunt narwhals. Orcas are impacting the equation of the food chain at the top due to the alarming rate of melting snow in the Arctic when in fact changes in the warmer waters usually happens from the bottom of the food chain and works its way up to the top of food chain.

Orcas in the Arctic impact the survival of the old dominant killing machine the polar bear as well the Inuit where narwhals have always been the key to their survival due to the large amount of Vitamin C, an essential ingredient to human diet contained in narwhals skin.

The changing climate is even forcing red fox to the territory of the arctic fox unlike anything else seen before beside the fact that the number of those beautiful polar bears have been shrinking in an alarming rate of 40% with the possibility of them getting on the endangered list if the climate change continues at the current rate. See this incredible documentary for yourself and maybe, just maybe, we can all help to stop the impending changing climate - or, at least, stem its growing tide.
