This is the pilot of the famous BBC documentary series ''Planet Earth'', and some scenes were also reused in the other episodes of the show!
Here we visit various habitats of our planet: from the poles to the New Guinea forests, from the Kalahari desert to the Okavango delta, and also visiting briefly the South African sea shores and the Siberian woodlands.
There are many memorable scenes of animals that try to survive, and I'll recall some of them:
1) A mother polar bear exits out of her den for the first time with her 6-week old cubs, and makes them discover their icy world. My favorite part of the episode
2) Some great white sharks catch (in slow motion) south African sea lions jumping out of water
3) An elephant herd in the Kalahari desert migrates towards the Okavango delta, and we see these elephants swimming underwater
4) Some birds of paradise try to attract and impress females, but unsuccessfully
5) Emperor penguins at the beginning try to survive the total darkness, and they all stay close for escape the cold. But in the end the sun returns and they all have newborn babies
6) In the Okavango delta part we see a comic bit of baboons trying to move in the flooded grasslands
In the ten minute featurette we see the behind-the-scenes work of the camera crew in the Okavango delta trying to film a pack of wild dogs that try to kill a river antelope, and in the end they eat an already dead antelope!
I recommend it to all persons that love nature and animals, because it's full of stunning footage from our planet, and let me say it: IT COULDN'T HAVE STARTED BETTER!
