NARRATOR:
Earth, a breathtaking planet

00:00:11,219 --> 00:00:15,181
that has supported life
for billions of years.

[energetic music playing]
4
00:00:18,977 --> 00:00:22,022
But it can be a challenging
and cruel home.

[thunder rumbling]
6
00:00:25,692 --> 00:00:29,863
From the beginning, creatures
have had to be tough to survive.
7
00:00:30,614 --> 00:00:32,198
[loud roar]
8
00:00:32,407 --> 00:00:36,327
Mass extinctions
wiped out entire species.
9
00:00:38,412 --> 00:00:41,875
From super volcanoes
to an asteroid apocalypse.
10
00:00:42,459 --> 00:00:44,085
[wind howling]
11
00:00:45,128 --> 00:00:49,883
From megafloods to a frozen
planet strangled by darkness
12
00:00:52,261 --> 00:00:55,972
With every disaster,
there was suffering,
13
00:00:57,516 --> 00:01:00,518
but each time life returned...
14
00:01:02,520 --> 00:01:04,314
even stronger.
15
00:01:07,234 --> 00:01:11,529
Witness the heart
and the hope of our planet.
16
00:01:15,533 --> 00:01:20,080
Travel back in time to see
how life fights back...
17
00:01:23,083 --> 00:01:24,834
and wins.
18
00:01:26,211 --> 00:01:30,215

[ethereal music playing]
20
00:01:54,281 --> 00:01:57,242
NARRATOR:
252 million years ago.
21
00:01:58,076 --> 00:02:01,830
At this time all our planet’s
continents are fused together
22
00:02:01,955 --> 00:02:06,292
in one giant landmass that
stretches from pole to pole.
23
00:02:08,086 --> 00:02:10,797
It is called, Pangaea.
24
00:02:13,383 --> 00:02:17,345
Its climate is a blistering
20 degrees hotter than today
25
00:02:17,762 --> 00:02:21,766
and its vast heartlands are
dominated by endless deserts.
26
00:02:22,934 --> 00:02:27,647
Life clings on here
but it is not an easy existence.
27
00:02:31,776 --> 00:02:34,696
And something is about to happen
28
00:02:34,905 --> 00:02:36,948
that will make it everything
29
00:02:37,115 --> 00:02:38,992
-much worse.
-[loud explosion]
30
00:02:41,787 --> 00:02:44,789
[bright music playing]
31
00:02:44,956 --> 00:02:46,833
Not all of Pangaea is barren.
32
00:02:47,709 --> 00:02:49,335
Towards both poles
33
00:02:49,502 --> 00:02:52,172
the temperatures are cooler
and forests grow.
34
00:02:54,341 --> 00:02:56,843
Conifers cover
these northern hills.
35
00:02:57,927 --> 00:02:59,679
[bird squawks]
36
00:02:59,804 --> 00:03:04,350
And, beneath their branches
life thrives.
37
00:03:05,935 --> 00:03:08,313
[soft roar]
38
00:03:09,689 --> 00:03:11,858
A young Gorgonopsian...
39
00:03:13,693 --> 00:03:15,445
on a mission...
40
00:03:24,830 --> 00:03:26,873
to irritate his brother.
41
00:03:29,876 --> 00:03:31,920
[soft growling]
42
00:03:32,087 --> 00:03:35,882
Oh well, how about a sneak
attack on his mother.
43
00:03:38,760 --> 00:03:42,472
These Gorgons are early,
distant relatives of mammals...
44
00:03:47,227 --> 00:03:48,770
and, long before the dinosaurs,
45
00:03:48,979 --> 00:03:51,231
[loud yawns]
46
00:03:51,440 --> 00:03:54,734
this is what an apex
predator looks like.
47
00:04:00,365 --> 00:04:03,576
In this world,
the only thing a Gorgon fears...
48
00:04:04,619 --> 00:04:06,162
is another Gorgon.
49
00:04:06,371 --> 00:04:07,747
[tense music playing]
50
00:04:07,914 --> 00:04:11,084

[loud roar]
52
00:04:31,187 --> 00:04:35,900
Bigger than a tiger, this
alpha bears the battle scars
53
00:04:36,109 --> 00:04:38,945
from years of defending
his position
54
00:04:41,448 --> 00:04:43,616
as leader of this family.
55
00:04:43,741 --> 00:04:46,953
[soft, enchanting music playing]
56
00:04:50,748 --> 00:04:53,459
He has fathered generations
of young Gorgons
57
00:04:54,210 --> 00:04:56,796
with this group of
three different mothers.
58
00:05:03,761 --> 00:05:05,972
In this overheated world,
59
00:05:06,181 --> 00:05:09,225
he has led his family up from
the baking plains
60
00:05:09,434 --> 00:05:12,228
to find food and shade
among these foothills.
61
00:05:14,439 --> 00:05:16,316
[tense music playing]
62
00:05:19,486 --> 00:05:21,196
[soft growling]
63
00:05:21,905 --> 00:05:24,574
But now, he smells trouble.
64
00:05:27,368 --> 00:05:32,582
Skulking in the shadows
a lone, younger male.
65
00:05:34,083 --> 00:05:36,336
These are his woods.
66
00:05:40,173 --> 00:05:44,010
Males will fight to the death
for the right to mate.
67
00:05:49,223 --> 00:05:51,142
This one is waiting to see
68
00:05:51,351 --> 00:05:55,646
if the old alpha shows
any signs of weakness.
69
00:06:05,490 --> 00:06:07,950
Not all creatures in
these northern forests
70
00:06:08,117 --> 00:06:10,203
survive by being aggressive.
71
00:06:10,328 --> 00:06:12,955
[shrieks]
72
00:06:13,873 --> 00:06:20,046
Some, like this burrowing Elph,
have to rely on their wits.
73
00:06:21,714 --> 00:06:23,174
[soft growling]
74
00:06:26,928 --> 00:06:29,389
Playing dead is one trick.
75
00:06:30,515 --> 00:06:32,475
[sniffs]
76
00:06:39,274 --> 00:06:40,858
It’s a good performance...
77
00:06:41,734 --> 00:06:43,528
if he can just hold on...
78
00:06:49,534 --> 00:06:51,035
-[shrieks]
-[dramatic music playing]
79
00:06:51,244 --> 00:06:52,745
Too late.

[tense music playing]
83
00:07:12,932 --> 00:07:16,727
Our young Gorgon
has run straight into a giant.
84
00:07:20,273 --> 00:07:22,275
A whole herd of them...
85
00:07:26,029 --> 00:07:27,613
Scutosaurus.
86
00:07:29,699 --> 00:07:33,035
Growing over 10 feet long
and weighing over a tone,
87
00:07:33,244 --> 00:07:36,289
these bulky plant eaters
are reptiles
88
00:07:36,456 --> 00:07:38,749
and some of the largest
creatures on Earth.
89
00:07:43,045 --> 00:07:44,422
They’re slow,
90
00:07:45,048 --> 00:07:49,594
but with creatures this size
he could easily be crushed.
91
00:07:52,513 --> 00:07:55,766
His frantic mum has only
now realized he’s missing.
92
00:07:55,891 --> 00:07:59,562
[Gorgon calling]
93
00:08:01,606 --> 00:08:06,319
As long as they remain calm
our little guy should be safe.
94
00:08:10,948 --> 00:08:14,202
But, across the plains below,
trouble is brewing.
95
00:08:14,369 --> 00:08:16,120
[thunder rumbling]
96
00:08:16,287 --> 00:08:18,789
The herd can sense it
and a thunderstorm.
97
00:08:19,582 --> 00:08:21,834
And they are getting restless.
98
00:08:22,334 --> 00:08:23,836
[thunder rumbling]
99
00:08:24,045 --> 00:08:26,464
Up here in the mountains,
lightning strikes are common.
100
00:08:29,050 --> 00:08:31,969
None of which is good
news for our youngster.
101
00:08:40,895 --> 00:08:44,065
NARRATOR:
252 million years before
102
00:08:44,190 --> 00:08:46,275
modern humans walked the Earth,
103
00:08:47,735 --> 00:08:49,695
all the continents are fused
104
00:08:49,820 --> 00:08:52,865
as one giant landmass
called Pangea.
105
00:08:54,742 --> 00:08:56,953
It is a dry desolate place,
106
00:09:00,415 --> 00:09:01,791
except at the poles
107
00:09:01,958 --> 00:09:04,210
where lush conifer
forests grow.
108
00:09:09,257 --> 00:09:11,050
[thunder rumbling]
109
00:09:11,175 --> 00:09:15,888
Here a sudden storm has spooked
a herd of giant Scutosaurus.
110
00:09:16,055 --> 00:09:18,057
[growling]
111
00:09:19,392 --> 00:09:22,728
Caught in the middle
is our young Gorgon.
112
00:09:23,938 --> 00:09:27,024
One wrong step
and he will be crushed to death.
113
00:09:32,864 --> 00:09:35,366
[dramatic music playing]
114
00:09:35,491 --> 00:09:37,577
[Gorgons calling]
115
00:09:42,999 --> 00:09:45,418
His panicked mom needs
to find him.
116
00:09:48,546 --> 00:09:50,590
[baby Gorgon calling]
117
00:09:50,757 --> 00:09:53,801
She spots him
and her every instinct is
118
00:09:53,968 --> 00:09:56,596
to save her son at all cost.
119
00:09:58,055 --> 00:10:00,182
[dramatic music playing]
120
00:10:13,905 --> 00:10:16,449
[Gorgon squeeze, cries]
121

[nostalgic music playing]
122
00:10:30,713 --> 00:10:33,883
Our mother succeeded in
protecting her little one.
123
00:10:37,011 --> 00:10:41,140
But, in doing so,
she made the ultimate sacrifice.
124
00:10:44,185 --> 00:10:45,936
He doesn’t want to leave
her side.
125
00:10:46,103 --> 00:10:47,605
[cries]
126
00:10:47,730 --> 00:10:51,692
[loud growling]
127
00:10:51,859 --> 00:10:54,820
But his father’s call
echoes through the forest.
128
00:11:00,952 --> 00:11:04,664
The old alpha leads the family
away from the panicked herd.
129
00:11:19,512 --> 00:11:23,599
After the storm,
the sun sets and the sky flares
130
00:11:23,766 --> 00:11:25,851
a spectacular blood red.
131
00:11:27,770 --> 00:11:29,355
It’s an ominous sign.
132
00:11:31,774 --> 00:11:35,986
Not far from our Gorgon family
the forces of nature are
133
00:11:36,153 --> 00:11:39,865
about to put on a show that will
bring all life to its knees.
134
00:11:41,992 --> 00:11:44,245
The mighty continent of Pangaea,
135
00:11:44,912 --> 00:11:47,832
the world’s single
landmass that has shaped life
136
00:11:47,957 --> 00:11:49,792
for almost 50 million years
137
00:11:51,586 --> 00:11:53,003
is being torn apart.
138
00:11:54,839 --> 00:11:56,507
[dramatic music playing]
139
00:11:56,632 --> 00:12:00,052
A vast system of rifts
is reshaping the landscape.
140
00:12:06,976 --> 00:12:11,188
Over thousands of years
pulses of volcanic activity
141
00:12:11,730 --> 00:12:13,858
have produced enough lava
142
00:12:14,484 --> 00:12:16,527
to cover the entire
United States
143
00:12:16,652 --> 00:12:20,156
in molten rock half a mile deep.
144
00:12:23,033 --> 00:12:25,703
Now, all the side to the rift
145
00:12:25,870 --> 00:12:29,415
is ramping up
for its biggest eruption yet.
146
00:12:35,964 --> 00:12:38,674
Emissions from these
volcanoes are already having
147
00:12:38,799 --> 00:12:40,718
a profound effect on life.
148
00:12:43,179 --> 00:12:46,098
The vast amounts of carbon
dioxide being pumped out
149
00:12:46,265 --> 00:12:51,771
are sending atmospheric
temperatures soaring and forcing
150
00:12:51,938 --> 00:12:55,775
animals like our Gorgon
family to take extreme measures.
151
00:12:58,778 --> 00:13:01,155
The rising heat
is driving our alpha
152
00:13:01,280 --> 00:13:03,240
to keep migrating higher.
153
00:13:05,034 --> 00:13:08,370
For every 1,000 feet higher
he leads his family,
154
00:13:08,495 --> 00:13:11,457
the temperature drops
almost four degrees.
155
00:13:14,085 --> 00:13:16,629
It isn’t just the heat
that threatens them.
156
00:13:16,796 --> 00:13:20,466
Gases from the volcanoes
are destroying the Ozone layer,
157
00:13:21,092 --> 00:13:23,135
and this father wears
the damage of
158
00:13:23,260 --> 00:13:25,763
too much UV radiation
on his back.
159
00:13:35,815 --> 00:13:38,859
Eventually our family of
Gorgons reach somewhere
160
00:13:39,026 --> 00:13:40,903
higher and cooler to rest.
161
00:13:42,947 --> 00:13:47,326
But unlike the heat, one threat
has followed them up here.
162
00:13:49,078 --> 00:13:53,165
One that is focused exclusively
on our protective father.
163
00:13:54,083 --> 00:13:59,171
The desperate lone rival has
been shadowing his every step
164
00:14:00,464 --> 00:14:04,677
waiting for the right time
to strike.
165
00:14:10,725 --> 00:14:12,601
NARRATOR: Dawn breaks
across the northern hills
166
00:14:12,768 --> 00:14:15,771
on the hot dry continent
of Pangea.
167
00:14:17,314 --> 00:14:19,817
The one giant landmass
on our planet.
168
00:14:20,984 --> 00:14:22,945
Volcanic activity
is making an already
169
00:14:23,112 --> 00:14:25,322
stifling world even hotter.
170
00:14:27,283 --> 00:14:29,034
To find cooler temperatures
171
00:14:29,201 --> 00:14:32,037
our Gorgon family has
climbed higher into the hills.
172
00:14:37,502 --> 00:14:40,129
They wake
in unfamiliar surroundings
173
00:14:40,296 --> 00:14:42,006
and they are starving.
174
00:14:42,923 --> 00:14:44,884
None have eaten in days....

[Suminia squeaks]
176
00:14:48,387 --> 00:14:53,058

[Suminia squeaks]

This should be no contest
for our hungry alpha.

These little

00:30:19,401 --> 00:30:21,152
the old alpha has won.
361
00:30:21,361 --> 00:30:23,404
[growling quietly]
362
00:30:29,661 --> 00:30:32,205
He leads his family on,
363
00:30:32,288 --> 00:30:34,958
but there is nowhere left to go.
364
00:30:38,128 --> 00:30:42,715
Their world is doomed
and even he can’t save them.
365
00:30:42,840 --> 00:30:45,343
[thunder rumbling]
366
00:30:48,471 --> 00:30:50,932
Eventually,
the northern eruptions
367
00:30:51,057 --> 00:30:53,726
will go on to release
more than 700 times
368
00:30:53,935 --> 00:30:55,520
more carbon dioxide
369
00:30:55,729 --> 00:30:59,357
than humans have produced
in our entire history.
370
00:31:03,611 --> 00:31:06,948
This extinction event
is the worst assault on life
371
00:31:07,073 --> 00:31:09,993
our planet has ever known.
372
00:31:12,162 --> 00:31:16,207
90% of all species
on Earth are wiped out.
373
00:31:18,626 --> 00:31:21,713
While this catastrophe makes
life impossible for most...
374
00:31:23,089 --> 00:31:26,885
a stubborn few species
manage to survive.
375
00:31:27,844 --> 00:31:33,683
[hopeful music playing]
376
00:31:39,647 --> 00:31:43,401
Close relatives of Elph
are among these survivors.
377
00:31:44,694 --> 00:31:46,905
By burrowing
and hibernating
378
00:31:47,030 --> 00:31:49,574
their kind withstand
everything the volcanoes
379
00:31:49,783 --> 00:31:53,036
can throw at them
and find ways to endure.
380
00:31:57,415 --> 00:31:59,000
This single event changes
381
00:31:59,209 --> 00:32:01,586
the entire direction
of evolution,
382
00:32:01,795 --> 00:32:04,380
as the few survivors
go on to establish
383
00:32:04,589 --> 00:32:07,842
all the animal dynasties
we know today.
384
00:32:11,637 --> 00:32:15,767
After 100,000 years
the volcanoes grow cold...
385
00:32:16,977 --> 00:32:20,271
but the world remains
a toxic wasteland.
386
00:32:21,898 --> 00:32:24,359
The atmosphere still
has carbon dioxide levels
387
00:32:24,484 --> 00:32:26,611
five times those of today.
388
00:32:32,117 --> 00:32:34,035
Millions of years pass,
389
00:32:34,202 --> 00:32:39,415
and slowly,
our wonderous planet heals.
390
00:32:42,418 --> 00:32:45,630
Helped by the most
lowly of the survivors...
391
00:32:46,714 --> 00:32:49,968
fungi, bacteria
392
00:32:50,135 --> 00:32:52,637
and photosynthetic algae.
393
00:32:58,726 --> 00:33:00,687
These tiny
life forms flourish in
394
00:33:00,854 --> 00:33:02,772
the carbon rich atmosphere
395
00:33:02,897 --> 00:33:06,776
and steadily consume
the excessive greenhouse gases.
396
00:33:10,780 --> 00:33:13,658
Earth finally begins to cool.
397
00:33:18,621 --> 00:33:23,960
[soft, hopeful music playing]
398
00:33:27,547 --> 00:33:32,010
[distant growling]
399
00:33:32,177 --> 00:33:36,681
10 million years later,
400
00:33:36,890 --> 00:33:39,976
free of
its poisonous volcanic legacy,
401
00:33:40,101 --> 00:33:42,311
Earth is renewed.
402
00:33:43,938 --> 00:33:45,982
Our planet
can once again support
403
00:33:46,191 --> 00:33:48,526
a rich array of habitats.
404
00:33:52,321 --> 00:33:54,532
In this empty paradise,
405
00:33:54,699 --> 00:33:59,495
life begins to reclaim
every corner of the planet...
406
00:34:01,289 --> 00:34:06,044
sparking an extraordinary
explosion in evolution.
407
00:34:06,211 --> 00:34:09,547
[dramatic instrumental]
408
00:34:19,056 --> 00:34:20,850
NARRATOR: 10 million
years have passed
409
00:34:20,975 --> 00:34:24,062
since the giant
northern eruptions fell silent.
410
00:34:25,521 --> 00:34:27,940
It’s taken this long
for the seas and forests
411
00:34:28,149 --> 00:34:29,692
to fully recover...
412
00:34:30,735 --> 00:34:33,237
and they are
teeming with life.
413
00:34:36,074 --> 00:34:38,076
On the shores of a shallow sea,
414
00:34:39,076 --> 00:34:41,037
the sand stirs.
415
00:34:43,081 --> 00:34:47,085
Eggs, laid months ago,
are hatching.
416
00:34:47,919 --> 00:34:50,046
[chirping softly]
417
00:34:50,213 --> 00:34:52,757
It is a baby Cyamodus...
418
00:34:54,676 --> 00:34:57,095
a new type of
hard-shelled reptile
419
00:34:57,554 --> 00:35:00,014
that has taken to
a life in the sea.
420
00:35:02,726 --> 00:35:04,602
They lay their eggs in the sand
421
00:35:04,811 --> 00:35:07,230
to protect them
from marine predators.
422
00:35:08,690 --> 00:35:12,401
[intense instrumental]
423
00:35:12,568 --> 00:35:15,738
But these days there
are predators everywhere.
424
00:35:20,993 --> 00:35:23,538
[growling quietly]
425
00:35:23,705 --> 00:35:26,249
A female Dongusuchus.
426
00:35:26,958 --> 00:35:29,877
She’s a new type
of feathered reptile.
427
00:35:41,514 --> 00:35:44,517
She is being watched
428
00:35:44,642 --> 00:35:46,769
by another Dongusuchus.
429
00:35:50,482 --> 00:35:51,816
A male.
430
00:35:51,983 --> 00:35:54,277
[growling quietly]
431
00:35:54,444 --> 00:35:57,488
He’s not looking for lunch,
he’s looking...
432
00:35:57,655 --> 00:36:00,158
for a lunch date.
433
00:36:02,202 --> 00:36:05,037
With his bright plumage
and cool moves,
434
00:36:05,246 --> 00:36:08,166
he’s hoping to impress her.
435
00:36:11,878 --> 00:36:14,922
She’s not sure, yet.
436
00:36:19,427 --> 00:36:21,846
But he’s got more moves.
437
00:36:27,810 --> 00:36:29,896
New types of
gliding reptiles
438
00:36:30,105 --> 00:36:34,525
called proto-Pterosaurs,
head for the sand.
439
00:36:36,527 --> 00:36:37,820
[growling quietly]
440
00:36:38,988 --> 00:36:40,990
The beach is getting busy.
441
00:36:44,077 --> 00:36:47,288
But our guy is not giving up
on his mating dance.
442
00:36:52,376 --> 00:36:54,545
Time to pull out all the stops.
443
00:36:59,050 --> 00:37:02,386
[growling quietly]
444
00:37:03,554 --> 00:37:06,349
-[roaring]
-[Dongusuchus squawking]
445
00:37:17,026 --> 00:37:20,488
Well, someone really
didn’t like his dancing.
446
00:37:23,241 --> 00:37:28,329
[soft, expansive music playing]
447
00:37:33,834 --> 00:37:35,920
Cymbospondylus.
448
00:37:39,590 --> 00:37:42,677
A new type of
giant marine reptile...
449
00:37:43,678 --> 00:37:45,846
that will come
to dominate the seas
450
00:37:46,055 --> 00:37:50,059
for the next 157 million years.
451
00:37:53,104 --> 00:37:56,190
[uplifting music playing]
452
00:37:56,357 --> 00:37:58,985
In the forests and mountains,
453
00:37:59,194 --> 00:38:01,988
in the water and in the air
454
00:38:02,822 --> 00:38:06,367
it is the reptiles
that have seized the moment.
455
00:38:10,914 --> 00:38:14,458
If there is one point in
the history of life on Earth
456
00:38:14,667 --> 00:38:17,712
that sums up
its limitless resilience...
457
00:38:18,712 --> 00:38:20,965
this is it.
458
00:38:34,353 --> 00:38:36,814
Only two hundred years ago
459
00:38:36,939 --> 00:38:40,276
Earth had some of the lowest
carbon dioxide levels
460
00:38:40,818 --> 00:38:42,820
that have ever existed.
461
00:38:46,031 --> 00:38:51,037
[insects chirping]
462
00:38:51,246 --> 00:38:54,040
But since
the Industrial Revolution
463
00:38:54,165 --> 00:38:57,001
they have risen by
over 50 percent.
464
00:38:57,210 --> 00:39:00,838
[car horns honking]
465
00:39:07,637 --> 00:39:11,057
Compared with
the history of life on Earth,
466
00:39:11,182 --> 00:39:15,311
today’s levels of carbon
dioxide are still not high...
467
00:39:19,773 --> 00:39:22,026
but it is
the speed of the change
468
00:39:22,235 --> 00:39:25,363
that is challenging
all living things.
469
00:39:34,205 --> 00:39:37,041
Recently,
action has been taken.
470
00:39:40,545 --> 00:39:44,465
In the next few years,
emissions could stop rising...
471
00:39:46,968 --> 00:39:48,886
but the extra greenhouse gases
472
00:39:49,011 --> 00:39:52,932
will remain in
our atmosphere for decades,
473
00:39:53,141 --> 00:39:55,559
possibly even centuries.
474
00:40:00,148 --> 00:40:01,857
If these levels are to drop,
475
00:40:01,982 --> 00:40:04,402
the key will lie in
our planet’s ability
476
00:40:04,569 --> 00:40:06,904
to absorb carbon dioxide.
477
00:40:11,367 --> 00:40:14,662
In our peat bogs
and sea grass meadows...
478
00:40:15,788 --> 00:40:18,165
oceans and forests.
479
00:40:18,916 --> 00:40:21,335
Nature already has
the best tools
480
00:40:21,544 --> 00:40:24,213
to turn the tide
on greenhouse gases.
481
00:40:26,966 --> 00:40:29,468
Protecting
and bolstering these habitats
482
00:40:29,635 --> 00:40:31,429
is the next great challenge
483
00:40:31,888 --> 00:40:34,515
in the fight against
global warming.
