Spring arrives in the polar regions, and the sun appears after an absence of five months; warmth and life return to these magical ice worlds - the greatest seasonal transformation on our planet is underway. Male Adelie penguins arrive in Antarctica to build their nests - it takes a good property to attract the best mates and the males will stop at nothing to better their rivals! But these early birds face the fiercest storms on the planet. In the Arctic, a polar bear mother is hunting with her cubs. Inland, the frozen rivers start to break up and billions of tons of ice are swept downstream in the greatest of polar spectacles. This melt-water fertilizes the Arctic Ocean, feeding vast shoals of Arctic cod and narwhal. The influx of freshwater accelerates the breakup of the sea-ice - an area of ice the size of Australia will soon vanish from the Arctic. On land, a woolly bear caterpillar emerges from the snow having spent the winter frozen solid. Caterpillars normally become moths within months of hatching, but life is so harsh here that the woolly bear takes 14 years to reach adulthood. Once mature it has only days to find a mate before it dies! Alongside the caterpillars white Arctic wolves race to raise their adorable cubs before the cold returns.

In many of the earth's natural wonders there is an abundance of animals. These can be a devastating threat to the people who live there, or they can provide a means of survival, but often at a high price. In the coastal salt marshes of northern Australia's Arnhem Land, Indigenous Australians still go hunting for the eggs of one of the world's most aggressive predators - the saltwater crocodile. Vanuatu is an island paradise in the south Pacific, but life here isn't perhaps as idyllic as it appears. Overfishing has reduced fish stocks, making food harder to come by for the indigenous islanders like 45-year-old Nigasau.
