As the ice ebbs and flows at the two poles with the change of seasons, killer whales team up on a hunt and a polar bear is forced to travel a great distance in search of food. Also, beluga whales and narwhals feast on Arctic cod.

The earth's extensive grasslands are featured, from West Africa's Sahel to the plains of Papua New Guinea. Among the animals featured are white-eared kob in the Sudan, golden eagles in Russia and antelopes in South Africa.

Plants take center stage in this exploration of coniferous and deciduous forests. These seasonal forests cover vast tracts of temperate regions, such as the endless forests of Siberia, Tasmania and large areas of Eastern Europe.

The rain forests are home to a vast number of animal and plant species, leading to intense competition for food. Footage includes jaguars on the hunt in the Amazon, gibbons traversing the canopy and flying frogs mating.

De lavvandede havområder langs jordens kontinenter udgør kun otte procent af klodens have.

Rundt om kontinenterne ligger verdenshavet. Det dækker næsten tre fjerdedele af jordoverfladen.

The making of the sprawling, ambitious series is documented. The show took three years to produce and required 2,000 days in the field and 71 cameramen filming across 204 locations in 62 countries.
