Both poles of our planet are covered with ice |
| [00:04.91] |
They're the largest and most demanding wildernesses of all |
| [00:10.86] |
Nowhere else on earth is seasonal change so extreme |
| [00:17.3] |
It causes the ice to advance and retreat every year |
| [00:21.86] |
and all life here is governed by that |
| [00:29.7] |
When the first polar explorers headed south |
| [00:33.30] |
giant cathedrals of ice marked their entry into uncharted territory |
| [00:39.18] |
Passing the towering spires |
| [00:41.77] |
they must have wondered what unearthly sights lay in store |
| [00:46.75] |
As they battled on the ice became increasingly dominant |
| [00:51.82] |
but nothing could have prepared them for the ice world |
| [00:55.64] |
that finally loomed into view |
| [00:59.45] |
Terra incognita - the unknown land |
| [01:04.60] |
At the southernmost extreme of our planet |
| [01:08.45] |
the continent of Antarctica |
| [01:10.99] |
is as large as the United States of America |
