This is a documentary series looking at the most dramatic wildlife spectacles on our planet. We see the impact of the melting of the arctic ice in the summer, the annual return of the salmon to spawn, where the Okavango turns many thousands of miles into a lush wetlands. We also see the impact of the migration of wildebeest on a pride of lions, the annual winter sardine run along the coast of Africa, and the great feast in the ocean when the plankton blooms.

Episodes:

1. The Great Melt
The spring thaw in the Arctic Circle triggers a race to breed for the region's wildlife, including polar bears, arctic foxes, belugas and narwhals.

2. The Great Salmon Run
Grizzly bears, bald eagles and wolves on the west coast of Canada and Alaska await the annual arrival of 500 million Pacific salmon.

3. The Great Migration
The great wildbeast, zebra and gazelle herds of East Africa follow the rains in search of fresh pasture.

4. The Great Tide
The sardine run along South Africa's east coast is the world's largest marine spectacle, as gannets, dolphins, sharks and Bryde's whales engage in a huge feeding frenzy.

5. The Great Flood
Millions of animals time their migration across the Kalahari Desert to coincide with the the annual flooding of Botswana's Okavango Delta.

6. The Great Feast
The summer plankton bloom in the north-east Pacific draws in animals in great numbers, from the billion-strong shoals of herring to migratory humpback whales.
