Natural World: Penguins of the Antarctic

INHALT

Having learnt to survive in the harshest habitat on Earth, Natural World looks at Antarcticas penguins who face a new threat to their existence from climate change.
Antarctica's penguins are some of the most endearing animals on Earth - but behind the comical behaviour is a continual struggle to survive the deadly cold. Each penguin has its own strategy - some rely on thick down coats and fat reserves, others migrate north for the winter, or stay on volcano heated islands.
