[President Obama] A few years ago,
Michelle and I visited Patagonia

00:00:24,120 --> 00:00:25,080
with our daughters.

4
00:00:26,560 --> 00:00:29,640
Amongst the snow-capped mountains
and crystal-clear lakes,

5
00:00:29,720 --> 00:00:32,200
we marveled at an increasingly rare thing.

6
00:00:33,000 --> 00:00:34,360
Untouched wilderness.

7
00:00:35,400 --> 00:00:38,360
Human influence has spread
far and wide across our planet.

8
00:00:39,040 --> 00:00:42,040
National parks can protect
what we still have.

9
00:00:42,560 --> 00:00:47,120
But if we are to make a real change,
we must return more of our land to nature.

[tranquil music continues]

11
00:00:51,120 --> 00:00:55,120
In Chilean Patagonia,
vast areas are being re-wilded,

13
00:00:57,840 --> 00:00:59,160

14
00:01:01,040 --> 00:01:05,560

one of the most protected places on Earth.

16

Chilean Patagonia is home
to 24 unique national parks…

17
00:01:17,240 --> 00:01:20,200
across an incredible
variety of landscapes.

18
00:01:22,520 --> 00:01:24,720
The longest mountain range in the world,

19
00:01:25,320 --> 00:01:29,200
the Andes,
runs like a spine along its length.

20
00:01:31,880 --> 00:01:34,360
At its heart, lush forests

21
00:01:36,160 --> 00:01:38,240
and the open Patagonian steppe.

22
00:01:39,880 --> 00:01:41,000
And along the coast,

23
00:01:42,280 --> 00:01:44,880
the raw power of the Pacific Ocean.

25

of what national parks could be.

[tranquil music continues]

28
00:02:16,320 --> 00:02:19,560
On the western seaboard
of South America lies Chile,

29
00:02:20,320 --> 00:02:22,000
the longest country in the world,

30
00:02:22,720 --> 00:02:27,760
stretching over 2,500 miles
from north to south.

31
00:02:29,880 --> 00:02:34,000
In the southern part
is the remote area of Chilean Patagonia,

32
00:02:35,480 --> 00:02:40,360
where huge swaths of land
are given over to its 24 national parks.

33
00:02:41,560 --> 00:02:45,240
The most famous of these
is Torres del Paine.

[tranquil music continues]

38
00:03:18,560 --> 00:03:23,760

00:03:25,080 --> 00:03:26,040
the puma.

40

For the best chance of success,

44
00:03:52,000 --> 00:03:54,200
she must leave the cubs behind.

of the domestic llama,

48

[tranquil music plays]

112
00:11:48,480 --> 00:11:52,560
Until recently, puma were believed
to be solitary creatures.

113
00:11:53,360 --> 00:11:56,840
Lions and cheetahs were thought
to be the only social big cats.

114
00:11:58,320 --> 00:12:01,440
The discovery of such strong social bonds

115

is redefining
how scientists think about pumas.

[tranquil music continues]

117
00:12:08,600 --> 00:12:12,960
The creation of this refuge
has protected these cats from ranchers

who might fear for their livestock.

119
00:12:16,760 --> 00:12:21,000
And it has also led to an increase
in space and prey,

120
00:12:21,080 --> 00:12:24,240
so there's less need
for conflict between rivals.

Puma and their prey,

After almost a year of pregnancy,

a mother is in labor.

thousands of baby guanaco

As these guanaco herds expand,

200
00:19:47,440 --> 00:19:51,840
so too will the opportunities
for the puma population to bounce back

201
00:19:53,480 --> 00:19:55,720
and for nature to recover.

Around the world,

as isolated pockets
of protected wilderness.

To really flourish,

207

animals need not only safeguarding,

208
00:20:17,440 --> 00:20:18,720
but safe passage.

209
00:20:19,680 --> 00:20:21,160
The ability to move freely

[tranquil music continues]

212
00:20:30,880 --> 00:20:33,760
Since 2017, Chile has been working

213
00:20:33,840 --> 00:20:36,640
to connect a patchwork of wild spaces,

214
00:20:38,160 --> 00:20:42,680
joining national parks with other
protected reserves and marine parks

215
00:20:44,120 --> 00:20:48,040
to create a network,
a wildlife conservation corridor,

216

of Chilean Patagonia.

At the center of this network

[tranquil music plays]

221
00:21:20,040 --> 00:21:21,640
The Andean condor.

222
00:21:27,920 --> 00:21:29,600
Condors are scavengers.

223
00:21:30,240 --> 00:21:31,600
They consume dead animals.

224
00:21:32,200 --> 00:21:36,320

In the past,

by landowners seeking
to protect their livestock.

228

But now the population
of these magnificent birds

They nest in these inaccessible,

232

And every day,
they travel hundreds of miles

233

He might almost be the size of an adult,

but this massive chick
is only nine months old.

241
00:22:48,760 --> 00:22:51,960
Condors are the world's
largest soaring birds.

242
00:22:53,680 --> 00:22:57,280
And he could eventually
have a wingspan of over ten feet.

For now though,

If he can.

To give him the best chance in life,

they will only raise one chick at a time.

But if all of their efforts
are to pay off,

he must take to the skies himself.

To stay aloft and travel long distances,

these giants were once a common sight

and now only exist
in small pockets of ancient woodland.

And the smallest wildcat of the Americas.

And under the cover of darkness,

366
00:34:21,400 --> 00:34:26,240
one nocturnal forest resident
is helping his home to regenerate.

367
00:34:31,440 --> 00:34:33,120
Using new camera technology,

368
00:34:33,200 --> 00:34:36,120
we can reveal his nighttime antics.

369
00:34:39,120 --> 00:34:40,600
The monito del monte.

373
00:34:52,520 --> 00:34:56,200
But the monito isn't a monkey.
He's a marsupial.

[jaunty music continues]

375
00:35:03,320 --> 00:35:04,800
And although he is tiny…

376
00:35:06,680 --> 00:35:10,720
these giant trees depend on him.

377
00:35:17,440 --> 00:35:21,440
He will eat his entire body weight
in food every night.

[tense music plays]

379
00:35:29,320 --> 00:35:34,040
During his lifetime, he will help spread
at least 20 different species of plant

380
00:35:34,920 --> 00:35:36,120
by eating the fruits…

381
00:35:38,720 --> 00:35:41,920
and dropping the seeds in new places.

[tense music continues]

383
00:36:02,960 --> 00:36:04,440
As dawn begins to break,

he returns to his hidden nest to sleep.

[tranquil music plays]

386
00:36:13,080 --> 00:36:14,680

[tranquil music continues]

388
00:36:19,080 --> 00:36:24,240
These communal nests can contain
up to ten unrelated monitos

[tranquil music continues]

391

With the help of these
"little monkeys of the mountain,"

392
00:36:48,320 --> 00:36:51,120
it is possible
that a huge Valdivian forest

393
00:36:51,960 --> 00:36:55,160
will once again stretch
from the Andean mountains

394
00:36:56,720 --> 00:36:57,960

they carved Patagonia's maze
of deep coastal fjords.

[jaunty music plays]

406
00:37:53,360 --> 00:37:55,800
Relatively few of these icy giants remain.

leopard seals have such high levels
of surging hormones…

and to the south,
the brutal Southern Ocean.

It's one of the world's
few albatross colonies not in decline,

487
00:43:59,760 --> 00:44:02,120
due to the lack of predators on the island

488

00:50:10,720 --> 00:50:15,040
It's helping bring animals
back from the brink of extinction.

545
00:50:16,680 --> 00:50:20,080
But it's not just wildlife
that is benefiting.

546
00:50:21,880 --> 00:50:26,000
Ecotourism is predicted
to bring hundreds of millions of dollars

547
00:50:26,080 --> 00:50:28,360
to the local economy
over the next ten years.

548
00:50:29,080 --> 00:50:31,200
And it will have a far greater benefit

549
00:50:31,920 --> 00:50:34,680
to every being on our planet.

550
00:50:36,320 --> 00:50:38,320
In the fight against climate change,

551
00:50:38,400 --> 00:50:42,080
this land and vegetation
act like a sponge,

552
00:50:42,160 --> 00:50:44,320
absorbing carbon dioxide,

553
00:50:45,240 --> 00:50:49,440
making the region one of the largest
carbon sinks in South America.

555
00:50:52,520 --> 00:50:55,560
Give nature a chance and it will return.

556
00:50:56,320 --> 00:50:59,120
Wilderness and wildlife can recover,

557
00:50:59,800 --> 00:51:02,040
and balance can be restored.

558
00:51:03,320 --> 00:51:06,640
Chilean Patagonia is an inspiring example

559
00:51:07,200 --> 00:51:11,000
of what can be achieved
when we work together with nature

560
00:51:11,520 --> 00:51:16,360
and believe in the true value
of our national parks.
