The frozen Arctic is home to polar bears and walruses, two very different types of animals whose struggle to survive against the elements is only being made more difficult by a changing climate. Directors Adam Ravetech and Sarah Robertson filmed walruses and polar bears in the Arctic for 15 years in order to create this amazing story about the lives of Nanu the baby polar bear and a newborn walrus dubbed Seelah. Striking footage from land and sea is combined with effective narration by Queen Latifa and pop music by Joby Talbot to chronicle these creatures' lives from the babies' first days of existence, through two years of training in hunting and fighting by their respective mothers and the changes in the icy world that are necessitating new adaptations by these animals, and a contemplation of the chances of both species' continued survival. Like March of the Penguins, the footage of the animals of the Arctic and the formation and breaking up of the ice is exquisite, but perhaps even more striking is the clear evidence of climate change in the delayed formation of the ice in the autumn and its progressively earlier thawing and breaking up each spring. The polar bears' and walruses' resilience and instinctual ability to adapt and change in the face of the negative effects of global warming in order to survive is stressed, and viewers are left pondering why man cannot similarly adapt and change his ways in order to positively affect the world.
