before the summer got so damned long.
355
00:43:40,451 --> 00:43:42,066
He 's curious, too.
356
00:43:42,578 --> 00:43:45,035
He gets to visit the human zoo.
357
00:43:56,050 --> 00:43:57,961
Business is booming.
358
00:43:58,427 --> 00:44:00,964
The tourist season lasts longer than ever,
359
00:44:01,055 --> 00:44:04,092
since the bears are stuck here
an extra month.
360
00:44:13,860 --> 00:44:17,944
Polar bears are crossing paths
with our world more and more.
361
00:44:19,866 --> 00:44:21,822
The encounter can get ugly.
362
00:44:21,951 --> 00:44:23,407
(BARKING)
363
00:44:29,584 --> 00:44:31,324
Dogs, like wolves,
364
00:44:31,878 --> 00:44:34,369
are ancient enemies of bears.
365
00:44:35,047 --> 00:44:39,256
But, this time, it's the pack that's at risk.
366
00:44:39,343 --> 00:44:40,833
(BARKING)
367
00:44:41,053 --> 00:44:45,547
The bear that's approaching
could not be more hungry.
368
00:44:47,643 --> 00:44:48,974
(GRUNTING)
369
00:44:56,652 --> 00:44:58,233
(BARKING)
370
00:45:01,407 --> 00:45:04,149
The ice bear could easily kill a dog.
371
00:45:17,548 --> 00:45:20,915
Instead, an extraordinary turn.
372
00:45:26,599 --> 00:45:30,012
That a bear wants companionship with dogs
373
00:45:30,144 --> 00:45:32,510
is a strange sign of the times.
374
00:45:39,028 --> 00:45:42,395
No less bizarre than that
he would need to wait for winter,
375
00:45:43,574 --> 00:45:45,735
so long overdue.
376
00:45:55,127 --> 00:45:56,788
(BARKING)
377
00:46:01,425 --> 00:46:05,134
For the ice bear,
company may be a consolation,
378
00:46:07,139 --> 00:46:08,595
but it's not the answer.
379
00:46:23,155 --> 00:46:25,146
(YAWNING)
380
00:46:30,997 --> 00:46:32,407
(BARKING)
381
00:46:41,674 --> 00:46:45,667
The ice is finally beginning to beckon.
382
00:46:52,935 --> 00:46:56,018
Come December, the waters roil.
383
00:47:06,032 --> 00:47:10,071
On the banks of Hudson Bay,
the weary gather.
384
00:47:14,665 --> 00:47:18,704
The ice bear has finally found his way
to others his age.
385
00:47:20,046 --> 00:47:21,502
(GROWLING)
386
00:47:24,091 --> 00:47:28,676
If they're going to compete for females,
they have to learn to spar
387
00:47:29,722 --> 00:47:32,555
and this is their last fleeting chance.
388
00:47:50,785 --> 00:47:54,573
A chance Ice Bear now seizes.
389
00:48:30,282 --> 00:48:32,944
A bond and rivalry forged on land
390
00:48:33,911 --> 00:48:36,493
may last them years on the ice.
391
00:48:55,808 --> 00:48:59,676
Finally, the sea turns from black to white.
392
00:49:07,445 --> 00:49:11,029
He 's survived one of the
longest summers on record.
393
00:49:11,866 --> 00:49:14,949
Nearly six months on land.
394
00:49:21,542 --> 00:49:25,330
His homecoming is a bay
once again entombed.
395
00:49:27,965 --> 00:49:31,002
Next year,
the summer may be longer than ever.
396
00:49:32,553 --> 00:49:36,796
The time to hunt seals on ice
may get even shorter.
397
00:49:39,768 --> 00:49:44,387
But, for now, the ice bear is home.
