Earth's Great Seasons

Àngels Barceló shows us how spring comes to our planet, from bear cubs to flowers in the desert. In addition, we discovered how animals face the challenges of this season.

With the sun shining and flowers blooming, summer is the season of splendid abundance, and the long hours of daylight make life burst out in a riot of activity. But, as this intriguing nature documentary illustrates, you have to find clever ways to get your share of the good times while they last. From sneaky ring-tailed lemurs to battling ibex, summer is a time when the living is not always easy.

With winter fast approaching, life has to get ready and that means feeding up while you can, fighting for the last chance to breed and rushing to grow up before the cold returns.

With their world encased in snow and ice, animals must find the most inventive ways to survive winter and even benefit from the cold. This remarkable nature documentary sees caribou become ice road travelers, stoats make their own fur bedding and snow monkeys find a warm bath. Emperor penguins are built for the weather, but even they must find their own tricks to endure the savage season.
