Natural world: disc 5 - living in extremes and disc 6 - journey to the centre of the earth
Natural history documentary about living in extremes. Earth is a planet of extremes. However, animals have developed to thrive in seemingly uninhabitable environments. In the freezing world of the Arctic, the polar bear has a coat of fur to cope with interminable winters. Mountain goats have developed their lungs to take advantage of thin air and bats have extraordinarily sensitive hearing to navigate in the darkest caves. Finally, in the mysterious deep of our oceans, fragile jellyfish are gelatinous enough to thrive in extreme water pressure.
Natural history documentary about the centre of the Earth. 'Journey to the Centre of the Earth' takes you where no man has ventured before - the Earth's core and beyond! We'll investigate man's attempts to penetrate the depths of the Earth's surface via deep drill holes, examine the creatures that live where life is seemingly insupportable and discover what would happen if you dug through to the other side of the Earth.
