Graingers World On Thin Ice DVD.

CLIMATE CHANGE SPECIAL

With predictions of polar bears being extinct in 50 years, ON THIN ICE

follows bears as they emerge from their dens and navigate their rapidly

changing environment. ON THIN ICE shows how the frozen expanses of

the Arctic are shrinking at an unprecedented rate, with the very survival of the polar bear literally on thin ice.

Over the last year, producer/presenter Greg Granger has mounted a series of expeditions across the

Arctic to document the plight of the polar bear.

• Researcher Nick Lunn tranquillises polar bears from his helicopter, cataloguing the diminishing health

of the Western Hudson Bay bear population and finding the remains of a bear thought to have died

from starvation.

team as they chase bears out of the township of Churchill, built in the

middle of the bears' migration route. Follow one family of bears that

have to be darted after they attempt to break into a building food for

food, while another bold bear becomes trapped inside a garbage

truck.

Hungry bears and husky dogs fighting one another at an isolated

weather station north of Norway.

There is no more iconic symbol of strength and adaptation to

survival than the polar bear.... an animal so superbly suited to its

environment that it thrives in the most hostile comers of the

planet - until now.
