Jean-Michel Cousteau travels with his son and daughter, Fabien and Celine, and team to the high Arctic to discover why some beluga groups are thriving and others are disappearing.
There are places on this planet where it's a marvel that
anything survives. In the cold Arctic waters of the far north, the
sea is alive with sound. The canaries of the sea are singing.
They're beluga whales, named from the Russian word for "white
ones." They're an evolutionary surprise - a warm-blooded mammal in
a numbingly cold sea. Resembling curious ghosts, these intelligent
mammals use one of the most complex sonars of any animal. In this
episode, Jean-Michel Cousteau travels with his team to the high
Arctic to determine why some beluga groups are thriving and others
are disappearing. There's a clear connection between human activity
and the beluga's future. The beluga's world is now ground zero for
climate change; what threatens them is not confined to the Arctic -
it's global. What lies ahead for the beluga could become prophecy
for many species everywhere, including our own.
