For a few months each year, the Arctic becomes "The land of the midnight sun"
and 24 hours of daylight allow animals to feed around the clock.
The arctic fox finally has enough food to raise her large family.
If you choose to nest in the open, you must be prepared for a fight.

The male polar bear's ice world has finally vanished beneath him.
While the female is still kept on land by her dependent cubs, the male can take to the sea in search of food.

He will drown if he doesn't find land somewhere in this vast ocean.
