冰雪世界 1

Both poles of our planet are covered with ice

They're the largest and most demanding wildernesses of all

Nowhere else on earth is seasonal change so extreme

It causes the ice to advance and retreat every year

and all life here is governed by that

When the first polar explorers headed south

giant cathedrals of ice marked their entry into uncharted territory

Passing the towering spires

they must have wondered what unearthly sights lay in store

As they battled on the ice became increasingly dominant

but nothing could have prepared them for the ice world

that finally loomed into view

Terra incognita - the unknown land

At the southernmost extreme of our planet

the continent of Antarctica

is as large as the United States of America
