In a spectacular and epic journey from north to south, from winter to spring, Alastair Fothergill and Mark Linfield filmed from very close to the seasonal life and labors of three families of the animal kingdom. Shipped to the North Pole, the authors have recorded the end of winter and the awakening of a family of polar bears struggling with the first steps of their puppies and the desperate search for food to turn off the accumulated fame in hibernation. Their goals are moved later in the vast and arid desert of the Kalahari, where raging sandstorms and blinding clouds of dust flying and confuse the progress slow and stubborn to a herd of elephants, an elephant mother and her cub directed to the Okavango Delta, still dry but soon fertile paradise, washed by the flow of water. Leaving the land to the oceans blue, the directors meet a humpback whale and her baby, engaged in his first lessons in swimming and breathing. In the warm waters of the equator, they do not know the seasons, but there is no support for the whales who travel to six thousand five hundred kilometers, to the far south of our planet (Antarctica), to satisfy their appetite and to stock of food.
The journey of our heroes is not without hazards, however formidable opponents and, stationed along the pools of water in the desert, hidden in the depths of the ocean, or provided with sharp fangs and slashing strokes to launch defend themselves and their pups helpless and defenseless. While the animals are struggling to survive on earth, the sky is crossed by a flock of ladies of Numidia, who face the most incredible migrations passing by getting wings against the air currents, the rugged peaks of the Himalayas to climates more temperate.
include elephants, whales, white sharks, lions, caribou, wolves and walrus, the polar bear is undoubtedly the symbol of the negative consequences of climate change in progress, the emblem of the complaint of an educational documentary, narrated (in Italy) by the popular voice of Paul Bonolis. Global warming has resulted in the premature melting of Arctic ice beneath the feet of the mighty bear, reducing the ice where they hunt and breed large carnivores. Driven by hunger on the high seas end up drowned in the icy water to more than one hundred kilometers from the coast.
Earth with grace and lyricism, looking at the planet and its creatures, there is no lack of emphasis on the peculiarities of the human species, that in the great natural system has taken a leading role dual and contradictory knowledge and destruction. A call for images to deal with the consequences of their activities may have on the environment, started to measure the effects.
