With winter temperatures of -70C and winds of 100mph, only a few hundred people live in this inhospitable continent that is one and a half times the size of Europe. The wildlife, however, is abundant - millions of penguins, thousands of whales and half the world's seals somehow survive some of the hardest conditions on the planet.

It's summer in Antarctica, and with 24-hour daylight the race to breed is on as two million fur seals crowd the beaches of South Georgia. When the pups are born, ferocious bulls attack any intruders who challenge their females. Meanwhile, chinstrap penguins cross glacial streams and climb near vertical cliffs to feed their chicks as formidable leopard seals lurk.
