1
00:00:34,243 --> 00:00:36,578
A Perfect Planet.
2
00:00:41,333 --> 00:00:44,211
Life flourishes on planet Earth...
3
00:00:52,469 --> 00:00:55,722
thanks to powerful natural forces.
4
00:01:02,271 --> 00:01:06,650
The weather gives us
predictable patterns of rainfall.
5
00:01:09,653 --> 00:01:14,950
Sunlight delivers energy
to all parts of planet Earth's surface.
6
00:01:17,744 --> 00:01:21,665
Ocean currents carry nutrients
around the globe.
7
00:01:26,378 --> 00:01:30,716
Volcanoes create and fertilise the land.
8
00:01:32,718 --> 00:01:37,306
Together, these forces
have helped shape our living planet.
9
00:01:41,518 --> 00:01:43,186
But it's a fragile system.
10
00:01:43,312 --> 00:01:45,105
All right, come on, let's get him in.
11
00:01:50,569 --> 00:01:55,365
This baby elephant
is dying of thirst.
12
00:01:55,490 --> 00:01:56,867
Big swallow.
13
00:01:59,286 --> 00:02:02,456
The latest casualty
of our changing world.
14
00:02:07,252 --> 00:02:12,299
Luckily, rescuers have found him,
so he has a chance.
15
00:02:20,390 --> 00:02:24,311
This young animal
is likely a victim of a new force...
16
00:02:26,146 --> 00:02:30,233
one so powerful
it threatens the future of life on Earth.
17
00:02:48,669 --> 00:02:51,296
For over 6O years,
I've been privileged
18
00:02:51,421 --> 00:02:55,467
to witness the natural world
in all its wonder.
19
00:02:56,593 --> 00:03:02,224
But the planet I saw as a young man
has changed beyond recognition.
20
00:03:03,975 --> 00:03:09,606
Human activity is now so dominant
it's disrupting the forces of nature
21
00:03:09,731 --> 00:03:13,735
and the vital habitats
that life needs to survive on Earth.
22
00:03:15,195 --> 00:03:18,490
This is the most important story
of our time.
23
00:03:18,615 --> 00:03:22,619
So I've asked three world authorities
from the front line
24
00:03:22,744 --> 00:03:24,913
to join me in telling it.
25
00:03:26,373 --> 00:03:30,335
Humans used to be a species
just like any other on Earth.
26
00:03:30,460 --> 00:03:33,338
But we've now become so populous
27
00:03:33,463 --> 00:03:35,340
and so destructive
28
00:03:35,465 --> 00:03:38,260
that we are the single most
influential creature on Earth.
29
00:03:39,428 --> 00:03:42,139
Everything around us is collapsing.
30
00:03:42,264 --> 00:03:45,142
This is the planet that we are
handing over to future generations,
31
00:03:45,267 --> 00:03:48,478
and the worst part, I'll tell you
the worst part, to me,
32
00:03:48,603 --> 00:03:51,064
is that they're going to turn around
and be like,
33
00:03:51,189 --> 00:03:53,900
"Why did you not do something
when you had the chance?"
34
00:03:54,025 --> 00:03:59,030
We are likely to lose
over half the species of life on Earth
35
00:03:59,156 --> 00:04:01,783
over the next eight decades.
36
00:04:01,908 --> 00:04:05,746
The last time we had an extinction event
of this magnitude
37
00:04:05,871 --> 00:04:07,664
was 65 million years ago.
38
00:04:08,790 --> 00:04:10,459
We are asleep.
39
00:04:10,584 --> 00:04:13,879
We are not taking a look
at the enormity of this event.
40
00:04:15,839 --> 00:04:19,468
If you want evidence
of how life is struggling to cope
41
00:04:19,593 --> 00:04:21,553
in our rapidly changing world...
42
00:04:23,221 --> 00:04:26,683
you need to look no further
than here in Africa.
43
00:04:31,229 --> 00:04:36,735
As we warm the planet, we create
more extreme droughts and floods,
44
00:04:36,860 --> 00:04:41,031
making it increasingly difficult
for many animals to survive.
45
00:04:43,450 --> 00:04:48,622
One of our planet's most magnificent
creatures is no exception.
46
00:04:56,546 --> 00:05:01,134
Adult elephants drink
around 200 litres of water a day.
47
00:05:07,057 --> 00:05:11,269
When rains fail,
as they did recently here in Kenya,
48
00:05:11,394 --> 00:05:14,314
watering holes quickly run dry...
49
00:05:15,607 --> 00:05:17,901
killing hundreds of them.
50
00:05:27,160 --> 00:05:29,663
You can see the scale of the problem...
51
00:05:31,581 --> 00:05:36,211
by the dozens of
orphaned baby elephants left behind.
52
00:05:40,674 --> 00:05:43,677
These are the lucky survivors.
53
00:05:47,597 --> 00:05:50,559
They owe their lives to Angela Sheldrick
54
00:05:50,684 --> 00:05:52,060
and her team,
55
00:05:52,185 --> 00:05:54,145
who rescue these young orphans.
56
00:05:54,271 --> 00:05:56,815
Come on. Come on, little boy.
57
00:05:56,940 --> 00:06:01,403
"ANGELA". The orphans, when we find them,
tend to be in a pretty sorry state.
58
00:06:08,827 --> 00:06:14,082
They are not only physically damaged
but psychologically too.
59
00:06:14,207 --> 00:06:17,419
Hey. Hello.
60
00:06:17,544 --> 00:06:22,132
They have suffered such a loss,
losing their elephant family,
61
00:06:22,257 --> 00:06:24,467
their mothers.
62
00:06:26,595 --> 00:06:31,516
Angela's team do their best
to soothe that loss.
63
00:06:41,234 --> 00:06:43,278
Come on.
64
00:06:43,403 --> 00:06:46,781
"ANGELA". The keepers replace
a lost elephant family.
65
00:07:01,087 --> 00:07:04,132
They provide the tender loving care
and the nurturing
66
00:07:04,257 --> 00:07:07,010
that is so important for them to heal.
67
00:07:10,138 --> 00:07:13,099
The keepers are there 24/7.
68
00:07:19,773 --> 00:07:26,321
It is a very, very special relationship
that actually does last a life time.
69
00:07:26,446 --> 00:07:28,323
Despite the elephants becoming wild,
70
00:07:28,448 --> 00:07:31,576
they do never forget
that love and kindness.
71
00:07:36,957 --> 00:07:42,045
The orphans have to be bottle-fed
eight times a day.
72
00:07:44,047 --> 00:07:46,299
"ANGELA". We raise these orphaned elephants
to ultimately
73
00:07:46,424 --> 00:07:48,510
go back to their birthright...
74
00:07:49,970 --> 00:07:51,930
a wild and happy life.
75
00:07:52,055 --> 00:07:55,058
You're such a clown!
76
00:08:00,897 --> 00:08:04,526
Hey.
77
00:08:07,779 --> 00:08:10,156
Come with me.
78
00:08:13,493 --> 00:08:15,453
Go on. Go on.
79
00:08:15,578 --> 00:08:18,456
So far, Angela's organisation
80
00:08:18,581 --> 00:08:22,711
has released
more than 150 orphaned elephants
81
00:08:22,836 --> 00:08:24,629
back into the wild.
82
00:08:24,754 --> 00:08:30,677
But to survive, they now need
to live in managed reserves,
83
00:08:30,802 --> 00:08:34,931
where people top up water supplies
when droughts return.
84
00:08:37,934 --> 00:08:42,480
"ANGELA". Over the years, we've seen an
enormous change in the weather patterns.
85
00:08:44,149 --> 00:08:45,692
Greater unpredictability.
86
00:08:47,235 --> 00:08:50,071
The drier seasons are drier and longer.
87
00:08:50,196 --> 00:08:52,574
It is the 11th hour now.
88
00:08:52,699 --> 00:08:56,036
We have just one home,
89
00:08:56,161 --> 00:09:00,081
and we, as the dominant species,
should take care of it...
90
00:09:01,249 --> 00:09:02,542
must take care of it.
91
00:09:02,667 --> 00:09:04,210
It is our responsibility.
92
00:09:07,839 --> 00:09:11,634
What! Need to say to people is,
this is not going to get better.
93
00:09:11,760 --> 00:09:16,389
We are on a curve that's moving us
with a series of events
94
00:09:16,514 --> 00:09:20,101
that's taking us
into a new geological era in history.
95
00:09:24,481 --> 00:09:29,110
To understand how humans
are destabilising our perfect planet,
96
00:09:29,235 --> 00:09:32,030
we need to look into the deep past.
97
00:09:34,324 --> 00:09:40,663
In Earth's long history, it's been through
at least five mass extinction events.
98
00:09:42,707 --> 00:09:46,294
Most were caused
by cataclysmic volcanic eruptions.
99
00:09:51,966 --> 00:09:55,762
It's not the lava or ash
that wiped out life...
100
00:09:59,557 --> 00:10:03,937
but an invisible gas
released by volcanoes
101
00:10:04,062 --> 00:10:05,772
called carbon dioxide...
102
00:10:07,023 --> 00:10:08,566
CO2.
103
00:10:10,735 --> 00:10:14,405
The single greatest extinction
event on the planet so far was caused
104
00:10:14,531 --> 00:10:17,492
by the superheating of the world.
105
00:10:19,577 --> 00:10:23,915
Masses of volcanic activity pumped huge
amounts of carbon into the atmosphere,
106
00:10:24,040 --> 00:10:26,376
massively raised the global temperature,
107
00:10:26,501 --> 00:10:31,673
and saw the destruction
of around 90% of all life on Earth.
108
00:10:33,049 --> 00:10:36,845
Humanity is now acting
like a super-volcano.
109
00:10:38,638 --> 00:10:42,892
We're releasing carbon dioxide
at an even greater rate
110
00:10:43,017 --> 00:10:48,648
than the prehistoric mega-eruptions
that extinguished life in the past.
111
00:10:56,865 --> 00:10:58,283
Here 3 the problem.
112
00:10:58,408 --> 00:11:01,077
Over the last two centuries,
113
00:11:01,202 --> 00:11:05,498
we dug up the burial grounds of
our previous geological era in history...
114
00:11:07,125 --> 00:11:08,668
the Carboniferous era.
115
00:11:08,793 --> 00:11:12,463
And we took those dead remains,
in the form of oil,
116
00:11:12,589 --> 00:11:15,383
gas and coal, and we made
117
00:11:15,508 --> 00:11:19,679
the entire industrial civilisation
based on these fossil fuels.
118
00:11:25,852 --> 00:11:31,608
Almost every part of modern life
depends on energy generated
119
00:11:31,733 --> 00:11:34,068
by burning these fossil fuels.
120
00:11:35,904 --> 00:11:39,199
And that produces CO2 in huge amounts.
121
00:11:42,577 --> 00:11:48,499
Globally, we now release 100 times
more carbon dioxide into the atmosphere
122
00:11:48,625 --> 00:11:51,711
than all Earth's volcanoes combined.
123
00:11:52,795 --> 00:11:56,299
Ana' by burning more fossil fuels,
releasing more carbon dioxide,
124
00:11:56,424 --> 00:11:58,218
heating up the world around us,
125
00:11:58,343 --> 00:12:03,640
we have become one of the most powerful,
destructive forces on the planet.
126
00:12:04,766 --> 00:12:08,603
Carbon dioxide acts like a blanket,
127
00:12:08,728 --> 00:12:10,897
trapping the sun's heat.
128
00:12:11,022 --> 00:12:13,316
This raises the temperature
129
00:12:13,441 --> 00:12:18,238
and so destabilises one of the most
important forces on Earth -
130
00:12:18,363 --> 00:12:20,031
the weather.
131
00:12:25,495 --> 00:12:30,708
Many animals rely on
predictable patterns of rainfall.
132
00:12:35,838 --> 00:12:41,052
But as our world warms,
our weather is changing.
133
00:12:44,472 --> 00:12:47,600
For every one degree
that the temperature
134
00:12:47,725 --> 00:12:51,020
goes up on this planet,
because of CO2 emissions...
135
00:12:54,732 --> 00:12:58,152
the atmosphere is sucking up
7% more water.
136
00:13:00,989 --> 00:13:04,242
So we're getting more concentrated
precipitation in the clouds...
137
00:13:06,411 --> 00:13:07,620
and more radical,
138
00:13:07,745 --> 00:13:11,457
extreme, unpredictable,
out-of-control weather events.
139
00:13:15,503 --> 00:13:18,798
Millions are bracing for a hurricane
the likes of which we've never seen.
140
00:13:18,923 --> 00:13:20,174
We are getting hurricanes
141
00:13:20,300 --> 00:13:24,804
that are devastating our ecosystems
and killing human beings every year.
142
00:13:27,765 --> 00:13:31,311
They're now over and over and over again
every season.
143
00:13:34,063 --> 00:13:36,983
This planet is more powerful
144
00:13:37,108 --> 00:13:38,151
than we thought.
145
00:13:42,655 --> 00:13:44,490
More fires, more droughts,
more floods.
146
00:13:46,326 --> 00:13:49,120
And so this perfect planet of ours is now
147
00:13:49,245 --> 00:13:51,164
being thrown into a system of flux.
148
00:14:01,257 --> 00:14:04,218
These extreme conditions are making it
149
00:14:04,344 --> 00:14:06,763
increasingly difficult
for animals to survive.
150
00:14:13,394 --> 00:14:16,898
And that is not just affecting wildlife.
151
00:14:21,277 --> 00:14:26,908
New research suggests that for every
one degree rise in global temperatures,
152
00:14:27,033 --> 00:14:32,246
a billion people will be pushed into
near unliveable extremes.
153
00:14:33,623 --> 00:14:39,212
And this could trigger one of
the greatest human migrations in history.
154
00:14:41,881 --> 00:14:43,716
We 're about to have
climate refugees,
155
00:14:43,841 --> 00:14:47,095
forced out of uninhabitable
areas of the world,
156
00:14:47,220 --> 00:14:48,513
pushed up into Europe.
157
00:14:53,017 --> 00:14:54,268
We are on the cusp
158
00:14:54,394 --> 00:14:58,106
of the biggest migratory pattern
159
00:14:58,231 --> 00:14:59,399
in human history.
160
00:15:01,150 --> 00:15:03,945
We're going to see millions,
tens of millions
161
00:15:04,070 --> 00:15:06,572
and, unfortunately,
hundreds of millions of people
162
00:15:06,697 --> 00:15:09,867
migrating from areas
that are no longer liveable
163
00:15:09,992 --> 00:15:13,663
in the next 20, 30, 40, 50 and 60 years.
164
00:15:15,665 --> 00:15:17,333
Ana' people are frightened -
165
00:15:17,458 --> 00:15:20,711
because this is outside
of our frame of reference.
166
00:15:26,426 --> 00:15:28,136
But there is hope.
167
00:15:30,930 --> 00:15:35,309
In Africa, the Sahara Desert
is advancing southwards.
168
00:15:35,435 --> 00:15:41,524
But a remarkable project
is aiming to stop it in its tracks.
169
00:15:48,197 --> 00:15:50,283
The ambitious goal
170
00:15:50,408 --> 00:15:54,787
is to plant over one billion
drought-resistant trees,
171
00:15:54,912 --> 00:15:56,747
like acacias.
172
00:15:56,873 --> 00:15:59,250
Known as the Great Green Wall,
173
00:15:59,375 --> 00:16:04,255
once complete, a band of trees
will stretch nearly 5,000 miles
174
00:16:04,380 --> 00:16:06,591
right across Africa...
175
00:16:08,342 --> 00:16:11,471
one of the largest living structures
on the planet.
176
00:16:13,931 --> 00:16:17,018
These trees stop topsoil blowing away,
177
00:16:17,143 --> 00:16:19,854
and their roots penetrate the ground,
178
00:16:19,979 --> 00:16:22,315
creating a network of channels
179
00:16:22,440 --> 00:16:26,068
that store water whenever rain falls.
180
00:16:29,822 --> 00:16:34,118
Ten-year-old Korka
is one of the first children to benefit.
181
00:16:47,089 --> 00:16:51,761
12 million trees have already been planted
here in Senegal,
182
00:16:51,886 --> 00:16:54,263
and with dramatic results.
183
00:16:57,934 --> 00:17:01,938
Wells are filling again,
allowing crops to grow.
184
00:17:31,133 --> 00:17:35,513
So far, only 15% of the Green Wall
is complete,
185
00:17:35,638 --> 00:17:39,058
but it's already breathing life
back into the land,
186
00:17:39,183 --> 00:17:41,102
stemming the exodus of people
187
00:17:41,227 --> 00:17:44,063
and keeping communities together.
188
00:17:49,277 --> 00:17:52,530
And the trees do something else
for our children's future.
189
00:17:56,826 --> 00:17:58,286
As they grow,
190
00:17:58,411 --> 00:18:02,456
they remove carbon dioxide from the air.
191
00:18:06,961 --> 00:18:11,215
Carbon is the very foundation of life.
192
00:18:12,967 --> 00:18:16,387
Every plant absorbs it from the air...
193
00:18:17,972 --> 00:18:19,849
using it to grow.
194
00:18:22,476 --> 00:18:24,228
When animals eat these plants,
195
00:18:24,353 --> 00:18:29,525
some of this carbon is locked away
in the fabric of their bodies.
196
00:18:33,446 --> 00:18:36,240
Together, these wild places,
197
00:18:36,365 --> 00:18:39,660
and the animals that allow them to thrive,
198
00:18:39,785 --> 00:18:44,540
take up over a third of the carbon dioxide
we release.
199
00:18:46,334 --> 00:18:48,586
"ASHA". All of these systems,
and the life within it,
200
00:18:48,711 --> 00:18:52,965
are so important to protect us
201
00:18:53,090 --> 00:18:55,092
from a warming planet.
202
00:19:00,056 --> 00:19:04,060
Some of the Earth's
most important carbon stores
203
00:19:04,185 --> 00:19:07,688
are those rich in plant
and animal species -
204
00:19:07,813 --> 00:19:10,358
the tropical jungles.
205
00:19:12,985 --> 00:19:14,528
"NXALL". Forests are sponges.
206
00:19:14,654 --> 00:19:17,448
They absorb enormous amounts of CO2
207
00:19:17,573 --> 00:19:19,909
from the atmosphere,
and they trap that inside.
208
00:19:23,371 --> 00:19:26,499
Forests are about
much more than just trees.
209
00:19:26,624 --> 00:19:30,795
In order to thrive, a jungle needs
bustling animal communities.
210
00:19:32,129 --> 00:19:34,340
It needs insects to pollinate.
211
00:19:34,465 --> 00:19:36,759
It needs mammals to spread the seeds
212
00:19:36,884 --> 00:19:38,594
from one part of the forest to another.
213
00:19:38,719 --> 00:19:42,890
It needs this massive
tangled web of species interactions.
214
00:19:44,183 --> 00:19:45,476
A jungle rich in animals
215
00:19:45,601 --> 00:19:49,021
stores so much more carbon
than a forest with little life.
216
00:19:54,694 --> 00:19:58,406
But many of the world's
tropical jungles are under threat.
217
00:19:59,657 --> 00:20:05,121
And none more so than the greatest
of them all, the Amazon rainforest.
218
00:20:09,500 --> 00:20:13,587
It's essential for the health of
our planet, storing as much carbon
219
00:20:13,713 --> 00:20:19,593
as 25 years' worth of current emissions
from all the cars in the world.
220
00:20:21,178 --> 00:20:25,141
The Amazon rainforest is one
of the keystones of our climate.
221
00:20:25,266 --> 00:20:29,103
If we lose enough of the Amazon
that it stops to function like that,
222
00:20:29,228 --> 00:20:33,566
then it's going to be an absolute disaster
for civilisation, it really will.
223
00:20:38,404 --> 00:20:41,824
But urban expansion,
cattle ranching
224
00:20:41,949 --> 00:20:45,911
and mining
means that the forests of the Amazon
225
00:20:46,036 --> 00:20:49,248
are being lost at a frightening rate.
226
00:20:54,670 --> 00:20:58,090
"NXALL". It's not beyond the realms
of possibility that we could
227
00:20:58,215 --> 00:21:02,762
deforest a rainforest, like the Amazon,
so that trees cannot grow there
228
00:21:02,887 --> 00:21:04,722
and it turns into a savanna.
229
00:21:10,686 --> 00:21:15,107
Every minute, an area
the size of about two football pitches
230
00:21:15,232 --> 00:21:17,401
is destroyed by humans.
231
00:21:17,526 --> 00:21:21,238
These amazing ecosystems around us -
the oceans, the jungles, the forests,
232
00:21:21,363 --> 00:21:24,241
the mangroves -
these are our greatest hope
233
00:21:24,366 --> 00:21:27,912
and our greatest buffers
against a warming planet.
234
00:21:32,291 --> 00:21:35,252
On the front line
in the heart of the Amazon
235
00:21:35,377 --> 00:21:37,797
stands of the city of Manaus.
236
00:21:39,965 --> 00:21:43,511
Here, urban expansion
is eating into the jungle.
237
00:21:58,651 --> 00:22:02,571
Celina Pinagé works for IPAAM,
238
00:22:02,696 --> 00:22:05,991
the Amazonas Environmental
Protection Unit.
239
00:22:07,284 --> 00:22:10,371
Their mission is to save animals
trapped in the city
240
00:22:10,496 --> 00:22:12,498
and to return them to the wild.
241
00:22:38,816 --> 00:22:42,403
Today, Celina is rescuing a sloth.
242
00:22:42,528 --> 00:22:45,489
It's the world's slowest mammal.
243
00:22:45,614 --> 00:22:49,201
Many become trapped as trees are cut down
244
00:22:49,326 --> 00:22:50,953
to make way for houses.
245
00:23:24,695 --> 00:23:29,617
Over 3,000 animals have been rescued
in the past five years.
246
00:23:32,661 --> 00:23:37,082
Each one of these creatures
is needed by the forest -
247
00:23:37,207 --> 00:23:40,586
to disperse seeds, pollinate plants
248
00:23:40,711 --> 00:23:44,798
or, like this jaguar,
to keep herbivores in check.
249
00:23:55,225 --> 00:24:01,565
Whenever possible, Celina releases animals
back into the protected areas of jungle.
250
00:24:30,636 --> 00:24:33,681
We don't just want to protect
animals because they are interesting
251
00:24:33,806 --> 00:24:35,099
and they're beautiful.
252
00:24:35,224 --> 00:24:39,645
They're an integral part of a functioning
planet, and we need to keep them around.
253
00:24:43,482 --> 00:24:47,820
So, how do we protect
our remaining forests?
254
00:24:47,945 --> 00:24:52,533
Calculating their true environmental value
could hold the key.
255
00:24:54,660 --> 00:24:59,248
And a new cutting-edge technology
is beginning to do just that.
256
00:25:01,375 --> 00:25:06,672
It's led by a team from
the Global Airborne Observatory.
257
00:25:06,797 --> 00:25:13,095
They've developed a way to quantify
exactly how much carbon the forest stores.
258
00:25:16,974 --> 00:25:20,561
By firing high-powered lasers
across the canopy,
259
00:25:20,686 --> 00:25:24,565
they can map the amount of carbon
within each tree.
260
00:25:30,612 --> 00:25:35,534
The trees showing up as red and yellow
are the most carbon rich.
261
00:25:38,662 --> 00:25:44,501
These maps allow countries
to see how valuable their forests are.
262
00:25:48,422 --> 00:25:51,258
I truly hope
that we aren't too far away
263
00:25:51,383 --> 00:25:55,387
from realising the intrinsic value
of wildlife, of forests,
264
00:25:55,512 --> 00:25:58,557
but we're not there yet,
and for the time being
265
00:25:58,682 --> 00:26:02,603
governments need to be financially
incentivised to keep forests standing
266
00:26:02,728 --> 00:26:04,438
and to not cut them down.
267
00:26:09,068 --> 00:26:13,614
But what about areas of forest
that have already been destroyed?
268
00:26:15,824 --> 00:26:19,995
In the Amazon,
a revolutionary project is under way.
269
00:26:23,749 --> 00:26:26,627
The aim is to plant a new jungle
270
00:26:26,752 --> 00:26:30,297
of 73 million trees.
271
00:26:35,302 --> 00:26:40,599
But regrowing a species-rich forest
has always proved difficult.
272
00:26:44,353 --> 00:26:49,775
So the project has turned to
the indigenous peoples of the Amazon,
273
00:26:49,900 --> 00:26:52,945
and young women like Milene Alves.
274
00:27:12,923 --> 00:27:16,927
Milene's community
has a unique knowledge of seeds.
275
00:27:22,558 --> 00:27:27,229
It's enabled them to collect over 200
of the most important tree species
276
00:27:27,354 --> 00:27:29,273
from across the Amazon.
277
00:28:03,974 --> 00:28:06,268
By mixing the seeds together,
278
00:28:06,393 --> 00:28:10,814
it allows them to create a super-recipe
known as a muvuca.
279
00:28:13,609 --> 00:28:19,698
In this mixture, there is enough
tree variety to jump-start a new jungle.
280
00:28:22,576 --> 00:28:25,329
Every year, around 20 tonnes of seeds
281
00:28:25,454 --> 00:28:29,166
are scattered over acres
of burnt and degraded land.
282
00:28:31,251 --> 00:28:32,669
After six yea rs,
283
00:28:32,794 --> 00:28:35,297
they will have restored an area of forest
284
00:28:35,422 --> 00:28:39,092
the size of 30,000 football fields...
285
00:28:40,302 --> 00:28:44,723
the largest tropical
restoration project in the world.
286
00:28:50,187 --> 00:28:52,022
"NXALL". The best thing we can possibly do
287
00:28:52,147 --> 00:28:55,525
to mitigate the effects of a warming
planet is to plant more trees
288
00:28:55,651 --> 00:28:57,861
and protect those trees that we have.
289
00:28:57,986 --> 00:28:59,112
We can do this.
290
00:28:59,238 --> 00:29:02,032
If we put them back, we are creating
291
00:29:02,157 --> 00:29:04,534
that stable climate
that we need to survive,
292
00:29:04,660 --> 00:29:06,119
and it's such an easy thing to do.
293
00:29:06,245 --> 00:29:11,333
Planting trees and saving wildlife
is a vital solution on land,
294
00:29:11,458 --> 00:29:13,961
but it's only part of the story.
295
00:29:14,086 --> 00:29:16,255
The carbon dioxide we produce
296
00:29:16,380 --> 00:29:19,091
is damaging another crucial part
of our planet-
297
00:29:19,216 --> 00:29:20,717
the oceans.
298
00:29:26,390 --> 00:29:30,519
Life cannot survive without them.
299
00:29:35,983 --> 00:29:38,318
The reason we can walk out and live
300
00:29:38,443 --> 00:29:40,737
and breathe oxygen is because
301
00:29:40,862 --> 00:29:42,572
it's generated in the oceans.
302
00:29:46,243 --> 00:29:51,206
The oceans produce
up to 70% of the oxygen we breathe
303
00:29:51,331 --> 00:29:54,876
and feed over three billion people.
304
00:29:59,673 --> 00:30:01,591
Just like our forests,
305
00:30:01,717 --> 00:30:06,972
the plants and animals here absorb vast
amounts of carbon from the atmosphere.
306
00:30:09,516 --> 00:30:12,644
And when they die,
it sinks down to the ocean floor.
307
00:30:16,315 --> 00:30:19,067
The ocean is what we call a carbon sink.
308
00:30:19,192 --> 00:30:21,403
Basically, it's a giant sponge
309
00:30:21,528 --> 00:30:27,534
that has forever been absorbing all
the excess carbon from the atmosphere,
310
00:30:27,659 --> 00:30:30,078
taking it down to the depths
and keeping it there.
311
00:30:31,413 --> 00:30:35,334
The most vital life forms
that allow the ocean to do this
312
00:30:35,459 --> 00:30:37,377
are some of the tiniest,
313
00:30:37,502 --> 00:30:41,673
microscopic plant-like organisms -
314
00:30:41,798 --> 00:30:44,051
phytoplankton.
315
00:30:44,176 --> 00:30:47,387
Now, we don't pay much attention
to the little teeny plankton.
316
00:30:47,512 --> 00:30:53,310
But plankton are the most important
organisms for taking carbon dioxide
317
00:30:53,435 --> 00:30:56,021
and transforming it into oxygen
for the planet.
318
00:30:57,564 --> 00:31:00,233
Phytoplankton are the base
of the food chain
319
00:31:00,359 --> 00:31:02,361
on top of which everything else survives.
320
00:31:02,486 --> 00:31:04,363
The krill eats the phytoplankton,
321
00:31:04,488 --> 00:31:06,740
whales eat the krill,
322
00:31:06,865 --> 00:31:09,701
sharks eat the fish,
and so on and so forth.
323
00:31:09,826 --> 00:31:13,747
We need phytoplankton for
everything else in the oceans to survive,
324
00:31:13,872 --> 00:31:17,334
to trap that carbon
and keep our climate cool.
325
00:31:18,627 --> 00:31:23,382
But some of these crucial
phytoplankton are under attack.
326
00:31:28,887 --> 00:31:31,598
Since the start
of the Industrial Revolution,
327
00:31:31,723 --> 00:31:37,020
the oceans have absorbed
almost half of all our CO2 emissions.
328
00:31:38,271 --> 00:31:40,982
But that has come at a cost.
329
00:31:46,446 --> 00:31:51,535
When water absorbs carbon dioxide,
it becomes more acidic.
330
00:31:54,371 --> 00:31:57,999
But the problem
when you have this acidification
331
00:31:58,125 --> 00:32:00,836
is that shells are made of
calcium carbonate,
332
00:32:00,961 --> 00:32:03,672
and as you have
this increased acidity in the oceans,
333
00:32:03,797 --> 00:32:05,757
it starts to dissolve these structures.
334
00:32:05,882 --> 00:32:10,053
That threatens anything with a shell.
335
00:32:10,178 --> 00:32:13,557
Our increasingly warm, acidic waters
336
00:32:13,682 --> 00:32:16,810
are not only destroying coral reefs
337
00:32:16,935 --> 00:32:19,813
but decimating some phytoplankton,
338
00:32:19,938 --> 00:32:24,234
the amount of which has fallen
by as much as 40% in recent years.
339
00:32:26,445 --> 00:32:33,034
250 million years ago, the ocean
also warmed and became more acidic,
340
00:32:33,160 --> 00:32:39,291
contributing to the mass extinction
of around 96% of all marine life.
341
00:32:40,709 --> 00:32:44,004
"ASHA". If we have less phytoplankton,
the base of every food web,
342
00:32:44,129 --> 00:32:46,673
you lose so much more of everything else.
343
00:32:49,092 --> 00:32:52,762
It is serious.
If we have less phytoplankton,
344
00:32:52,888 --> 00:32:58,143
we have less oxygen,
which is what we need to survive.
345
00:33:01,980 --> 00:33:03,899
And the oceans are being damaged
346
00:33:04,024 --> 00:33:06,568
in another way.
347
00:33:06,693 --> 00:33:09,654
Research suggests that overfishing
348
00:33:09,779 --> 00:33:14,951
has removed as much as 90%
of all large predatory fish.
349
00:33:15,076 --> 00:33:19,789
And fewer fish means
a marine system that stores
350
00:33:19,915 --> 00:33:20,957
less carbon.
351
00:33:22,000 --> 00:33:26,296
Ocean species are dying
at a rate that's so fast
352
00:33:26,421 --> 00:33:29,549
that if it were human beings
we would absolutely be terrified.
353
00:33:35,639 --> 00:33:37,098
But there is hope here, too.
354
00:33:41,228 --> 00:33:43,438
When areas of ocean are protected,
355
00:33:43,563 --> 00:33:46,525
marine life can recover.
356
00:33:50,403 --> 00:33:52,280
Here, off the coast of Gabon,
357
00:33:52,405 --> 00:33:55,534
they've created one of Earth's
most ambitious networks
358
00:33:55,659 --> 00:33:57,994
of marine protected areas.
359
00:34:01,748 --> 00:34:05,043
It's a hot spot
for breeding whales and dolphins...
360
00:34:08,755 --> 00:34:11,716
and one of the most important
of all marine predators...
361
00:34:13,969 --> 00:34:15,679
sharks.
362
00:34:16,888 --> 00:34:21,935
Sharks prevent the species they feed on
from becoming overabundant,
363
00:34:22,060 --> 00:34:26,398
an essential factor in maintaining
our oceans' rich diversity.
364
00:34:28,066 --> 00:34:31,069
When people think
about poaching in Africa,
365
00:34:31,194 --> 00:34:34,531
they think about elephants
and rhinos and hippos
366
00:34:34,656 --> 00:34:37,409
and these great, majestic
creatures on land.
367
00:34:37,534 --> 00:34:41,288
But there is poaching
that's taking place at sea.
368
00:34:42,372 --> 00:34:47,377
The reason that I call these fishermen
poachers is that they are taking wildlife
369
00:34:47,502 --> 00:34:49,754
without licence.
370
00:34:49,879 --> 00:34:52,591
Captain Peter Hammarstedt,
who works for the conservation group.
371
00:34:52,716 --> 00:34:54,593
Sea Shepherd,
372
00:34:54,718 --> 00:34:59,055
is patrolling the 20,000-square-mile
marine park.
373
00:35:00,390 --> 00:35:03,977
Prepare boats for launch,
prepare boats for launch. Thank you.
374
00:35:04,102 --> 00:35:08,857
They've spotted a commercial
fishing boat on the edge of the park
375
00:35:08,982 --> 00:35:11,359
which needs investigating.
376
00:35:13,653 --> 00:35:16,656
The Gabonese government has joined forces
with Peter's team
377
00:35:16,781 --> 00:35:18,658
to carry out boat inspections.
378
00:35:21,244 --> 00:35:25,790
The vessel may have
a licence to fish here,
379
00:35:25,915 --> 00:35:28,251
but it could be taking more than its quota
380
00:35:28,376 --> 00:35:30,545
and catching protected species,
381
00:35:30,670 --> 00:35:33,173
like dolphins and sharks.
382
00:35:41,348 --> 00:35:43,475
When fighting a war
to stop illegal fishing,
383
00:35:43,600 --> 00:35:46,978
the odds can seem insurmountable.
384
00:36:11,419 --> 00:36:14,130
This boat's fishing nets
have pulled up
385
00:36:14,255 --> 00:36:16,257
threatened silky and blue sharks.
386
00:36:19,636 --> 00:36:23,973
Catching and keeping
these creatures is illegal,
387
00:36:24,099 --> 00:36:27,811
so the fishermen must throw them back.
388
00:36:27,936 --> 00:36:32,816
But many are already so badly injured
they will not survive the ordeal.
389
00:36:34,442 --> 00:36:38,071
It saddens me greatly
to see these incredible creatures
390
00:36:38,196 --> 00:36:43,034
being brutally manhandled
as they're dragged across the deck,
391
00:36:43,159 --> 00:36:46,329
their fingers in their gills
as they pull them.
392
00:36:51,459 --> 00:36:55,088
Globally each year, millions of sharks
393
00:36:55,213 --> 00:37:01,010
and over 300,000 whales and dolphins
are accidentally killed by fishing nets,
394
00:37:01,136 --> 00:37:04,347
seriously injuring
the health of the oceans.
395
00:37:04,472 --> 00:37:09,269
Its the efficiency of these
vessels that shocks me to the core...
396
00:37:10,437 --> 00:37:13,064
this sheer killing power of them.
397
00:37:14,733 --> 00:37:16,693
And you can really see
398
00:37:16,818 --> 00:37:20,363
why the oceans are being
sucked dry of life.
399
00:37:36,171 --> 00:37:38,631
But the patrols are working.
400
00:37:38,757 --> 00:37:43,219
In the past three years,
they have arrested 50 vessels
401
00:37:43,344 --> 00:37:45,555
and inspected hundreds more.
402
00:37:46,681 --> 00:37:48,975
"PETER".
Last year, we assisted the coastguard
403
00:37:49,100 --> 00:37:52,061
to arrest a vessel
that was poaching sharks.
404
00:37:52,187 --> 00:37:54,647
And by arresting this one single ship,
405
00:37:54,773 --> 00:37:58,943
we were able to save the lives
of 250,000 sharks.
406
00:38:02,113 --> 00:38:06,159
Marine life here now has a chance.
407
00:38:08,119 --> 00:38:12,081
Currently, around 5%
of the oceans are protected,
408
00:38:12,207 --> 00:38:16,795
but there's a global campaign
to raise that to 30%.
409
00:38:18,087 --> 00:38:22,634
If we can do that, many of the planet's
most vulnerable species
410
00:38:22,759 --> 00:38:24,803
could recover.
411
00:38:24,928 --> 00:38:30,225
And a healthier ocean has the power
to absorb more CO2.
412
00:38:33,061 --> 00:38:34,687
We thought the ocean is
413
00:38:34,813 --> 00:38:40,026
this infinite space that is
full of infinite resources...
414
00:38:41,152 --> 00:38:44,364
and this infinite capacity to
415
00:38:44,489 --> 00:38:48,201
withstand and tolerate
everything that we throw at it.
416
00:38:49,911 --> 00:38:51,663
And I think we do need to...
417
00:38:51,788 --> 00:38:57,085
stop and reconsider our strategies
if we want to move forward.
418
00:39:02,465 --> 00:39:06,511
Humans aren't just damaging
life in the sea.
419
00:39:06,636 --> 00:39:11,307
We're also disturbing
one of its most important forces...
420
00:39:15,728 --> 00:39:17,856
ocean currents.
421
00:39:22,318 --> 00:39:28,700
These transport essential nutrients
to almost all marine creatures.
422
00:39:28,825 --> 00:39:30,326
We're dependent on
423
00:39:30,451 --> 00:39:33,204
these large circulation patterns
that go on in our oceans.
424
00:39:34,789 --> 00:39:36,749
There's this continuous movement
425
00:39:36,875 --> 00:39:39,085
of beautiful cold water
coming from the depths.
426
00:39:40,628 --> 00:39:41,796
It's chock-full of nutrients,
427
00:39:41,921 --> 00:39:43,201
it's chock-full of productivity.
428
00:39:44,883 --> 00:39:48,303
These currents begin at the poles.
429
00:39:50,430 --> 00:39:51,681
Here, cold, salty water,
430
00:39:51,806 --> 00:39:54,851
which is more dense,
sinks to the depths...
431
00:39:56,853 --> 00:39:59,105
and flows towards the tropics
432
00:39:59,230 --> 00:40:00,690
and beyond.
433
00:40:03,860 --> 00:40:08,489
In the hotter parts of the Earth,
warmer water rises and flows
434
00:40:08,615 --> 00:40:10,450
back towards the poles.
435
00:40:11,576 --> 00:40:14,537
This creates a global conveyor belt
436
00:40:14,662 --> 00:40:18,833
that circulates nutrients, oxygen
and heat around our planet,
437
00:40:18,958 --> 00:40:22,295
regulating Earth's climate and weather.
438
00:40:23,588 --> 00:40:29,302
But it's now feared that our warming
planet is destabilising the system.
439
00:40:31,346 --> 00:40:34,182
As you have an increase
in ocean temperatures,
440
00:40:34,307 --> 00:40:36,017
it has impacts on everything.
441
00:40:36,142 --> 00:40:38,436
We have glaciers across the world,
and as they melt,
442
00:40:38,561 --> 00:40:41,981
you have more of this fresh water
just pushing into the oceans.
443
00:40:42,106 --> 00:40:46,235
And this fresh water is
less saline, it's less salty,
444
00:40:46,361 --> 00:40:49,572
and that tends to float at the surface.
445
00:40:50,865 --> 00:40:54,285
And it's not moving.
You don't have this circulation.
446
00:40:54,410 --> 00:40:56,496
It's causing a breakdown.
447
00:40:57,872 --> 00:41:01,709
Many animals depend on
reliable ocean currents,
448
00:41:01,834 --> 00:41:03,670
so, as they change,
449
00:41:03,795 --> 00:41:06,631
the effect can be disastrous.
450
00:41:08,800 --> 00:41:10,176
This can be witnessed
451
00:41:10,301 --> 00:41:13,554
off the north-east coast
of the United States,
452
00:41:13,680 --> 00:41:15,390
where it's thought to be triggering
453
00:41:15,515 --> 00:41:19,435
mass casualties of
a critically endangered species.
454
00:41:20,937 --> 00:41:24,607
The fact that they're
even here just stuns so many people.
455
00:41:24,732 --> 00:41:29,028
Bob Prescott heads up
the emergency response team.
456
00:41:35,034 --> 00:41:38,371
We have about 250 people
that walk beaches.
457
00:41:38,496 --> 00:41:40,790
They're looking for
turtles in trouble.
458
00:41:42,834 --> 00:41:44,269
"NEWS". This week's frigid conditions
459
00:41:44,293 --> 00:41:46,713
have stunned sea turtles and left them
460
00:41:46,838 --> 00:41:49,007
stranded on beaches
throughout the north-east.
461
00:41:49,132 --> 00:41:52,677
If you spot one, move the turtle
above the high-tide line
462
00:41:52,802 --> 00:41:55,847
until a trained responder arrives.
463
00:41:55,972 --> 00:41:57,348
Timing is everything.
464
00:41:57,473 --> 00:41:59,809
If we can get to them within an hour
465
00:41:59,934 --> 00:42:01,853
of them washing up onto the beach,
466
00:42:01,978 --> 00:42:04,063
then we're going to be able to save
467
00:42:04,188 --> 00:42:06,691
90 to 95% of them.
468
00:42:07,859 --> 00:42:10,361
Here, off the coast of Boston,
469
00:42:10,486 --> 00:42:13,948
waters are warming faster
than almost anywhere on Earth.
470
00:42:15,241 --> 00:42:18,578
It's thought to be causing turtles
from the tropics to swim
471
00:42:18,703 --> 00:42:22,206
further north than ever before
for summer feeding.
472
00:42:24,083 --> 00:42:26,586
But when the cold autumn waters
suddenly close in,
473
00:42:26,711 --> 00:42:29,380
the turtles go into shock.
474
00:42:31,758 --> 00:42:34,093
These are very young turtles.
475
00:42:34,218 --> 00:42:35,928
They're anywhere from one and a half
476
00:42:36,054 --> 00:42:37,221
to six years old.
477
00:42:38,556 --> 00:42:41,059
When we find them, they're hypothermia,
478
00:42:41,184 --> 00:42:44,771
their heart is beating
at one to five beats a minute.
479
00:42:44,896 --> 00:42:47,231
The blood is barely circulating.
480
00:42:47,356 --> 00:42:50,151
For all intents and purposes, look dead.
481
00:42:50,276 --> 00:42:51,736
The critically ill animals
482
00:42:51,861 --> 00:42:55,198
are rushed to the New England Aquarium,
near Boston.
483
00:42:55,323 --> 00:43:00,536
It has a state-of-the-art
ER unit for turtles.
484
00:43:02,163 --> 00:43:04,248
We don't want to stress them
any further,
485
00:43:04,373 --> 00:43:06,793
so we now treat the whole episode
486
00:43:06,918 --> 00:43:09,003
as sort of entering an ICU unit
of a hospital.
487
00:43:10,505 --> 00:43:13,382
This is critical care for some turtles.
488
00:43:13,508 --> 00:43:17,386
He's pretty stiff,
so I can't get his mouth open any more.
489
00:43:17,512 --> 00:43:19,263
See, it's right there.
490
00:43:19,388 --> 00:43:21,099
Oh, there we are, there we are.
491
00:43:22,642 --> 00:43:27,021
When a turtle arrives,
its condition is rapidly assessed.
492
00:43:27,146 --> 00:43:29,273
- How you doing?
- The animals are given
493
00:43:29,398 --> 00:43:31,734
stabilising drugs and fluids.
494
00:43:31,859 --> 00:43:34,237
Their lungs are cleared of water
495
00:43:34,362 --> 00:43:36,781
and sand washed out
of their scratched eyes.
496
00:43:39,951 --> 00:43:41,953
Got emergency meds.
497
00:43:42,078 --> 00:43:43,621
The veterinary team
498
00:43:43,746 --> 00:43:45,164
must ventilate turtles
499
00:43:45,289 --> 00:43:47,208
that are close to death
500
00:43:47,333 --> 00:43:49,252
- to help them breathe.
- No response at all.
501
00:43:49,377 --> 00:43:54,632
But it's worth it for an animal
that might live another 50 years.
502
00:43:56,592 --> 00:43:58,594
"BOB". You want to save as many as you can.
503
00:43:59,637 --> 00:44:01,055
And it is depressing at times,
504
00:44:01,180 --> 00:44:03,224
cos a lot of them don't make it.
505
00:44:07,937 --> 00:44:11,941
You know, last year at Thanksgiving,
we had 200 dead turtles.
506
00:44:14,819 --> 00:44:19,198
Right, and you're looking into its eyes,
it's looking back at you.
507
00:44:19,323 --> 00:44:20,950
There is a connection there.
508
00:44:22,326 --> 00:44:25,872
And it gets stronger and stronger
as they start to recover.
509
00:44:28,374 --> 00:44:31,919
It can take months
for the turtles to recuperate.
510
00:44:32,044 --> 00:44:33,337
But once they do,
511
00:44:33,462 --> 00:44:37,175
they'll make the first plane flight
of their lives.
512
00:44:37,300 --> 00:44:39,969
We have a big transport
this morning,
513
00:44:40,094 --> 00:44:42,263
44 ridleys and one loggerhead.
514
00:44:42,388 --> 00:44:44,473
So we're going to start in 15B.
515
00:44:44,599 --> 00:44:47,310
All right, let's get to work!
516
00:44:48,769 --> 00:44:50,229
"BOB". They are part of the planet.
517
00:44:51,397 --> 00:44:55,860
They're part of our very delicate
web of life, if you will.
518
00:44:55,985 --> 00:44:59,155
38, 41, 44...
519
00:44:59,280 --> 00:45:03,826
The bottom line for all these turtles
is to get them back out into the water.
520
00:45:06,621 --> 00:45:10,124
We're doing great on timing,
everybody.
521
00:45:13,377 --> 00:45:16,380
A very exciting day,
cos it just brings that turtle
522
00:45:16,505 --> 00:45:19,759
one step closer to being released
back into the wild.
523
00:45:21,427 --> 00:45:24,597
These mass casualties
of our changing oceans
524
00:45:24,722 --> 00:45:28,768
are to be flown south,
to Florida and beyond.
525
00:45:28,893 --> 00:45:33,314
The future of this species
depends on these young turtles...
526
00:45:33,439 --> 00:45:34,815
- Ready.
- All right!
527
00:45:34,941 --> 00:45:36,025
Which will be released
528
00:45:36,150 --> 00:45:40,196
into the warmer-water currents
that they need to survive.
529
00:45:43,324 --> 00:45:45,743
It's a very emotional day
for everybody.
530
00:45:45,868 --> 00:45:48,704
These are turtles that staff
and volunteers at the aquarium
531
00:45:48,829 --> 00:45:51,249
have worked so hard
to get them to that point.
532
00:46:12,353 --> 00:46:16,315
Changes in the ocean currents
won't just harm turtles.
533
00:46:16,440 --> 00:46:21,404
With heat, oxygen and nutrients
moving more slowly around the globe,
534
00:46:21,529 --> 00:46:24,740
the impact on all life could be dramatic.
535
00:46:24,865 --> 00:46:26,617
I mean, we live in a world
536
00:46:26,742 --> 00:46:29,996
where just one domino
in a large game of dominoes,
537
00:46:30,121 --> 00:46:33,833
so you flick one piece, and you know what
happens - everything starts to collapse.
538
00:46:33,958 --> 00:46:36,669
And that's exactly what
we start to see over time
539
00:46:36,794 --> 00:46:38,379
as these conveyor belts slow down.
540
00:46:42,758 --> 00:46:47,930
Human activity is destroying
the balance of our perfect planet...
541
00:46:50,266 --> 00:46:53,519
disturbing our oceans
and disrupting our weather.
542
00:46:54,687 --> 00:46:58,149
But can we prevent the damage we're doing?
543
00:46:59,608 --> 00:47:02,069
"EREMY". Now, the human population's
at seven billion.
544
00:47:02,194 --> 00:47:04,071
It's moving to nine billion.
545
00:47:04,196 --> 00:47:08,367
And the problem is, we're already using
the equivalent of one and a half Earths.
546
00:47:11,287 --> 00:47:12,872
It's not sustainable.
547
00:47:15,082 --> 00:47:18,461
Around 80% of the energy we use
548
00:47:18,586 --> 00:47:22,840
still comes from burning fossil fuels.
549
00:47:22,965 --> 00:47:26,385
It's what makes us so dangerous.
550
00:47:27,678 --> 00:47:32,141
We can reduce CO2 emissions
by consuming less
551
00:47:32,266 --> 00:47:36,145
or reusing some of our resources.
552
00:47:36,270 --> 00:47:38,773
But the biggest saving we could make
553
00:47:38,898 --> 00:47:42,485
would be to stop using
fossil fuels for our energy.
554
00:47:43,569 --> 00:47:45,738
And there are many people who think
555
00:47:45,863 --> 00:47:52,036
that we could exploit the natural forces
of the planet to enable us to do that.
556
00:47:56,499 --> 00:47:59,835
The sun does not send us a bill.
557
00:47:59,960 --> 00:48:02,129
The wind has not invoiced us.
558
00:48:05,966 --> 00:48:10,388
Coal, oil, gas, uranium,
they're expensive.
559
00:48:10,513 --> 00:48:11,722
The sun and the wind is free.
560
00:48:17,603 --> 00:48:22,233
"ASHA". We live on a planet
that's incredibly dynamic.
561
00:48:26,320 --> 00:48:27,738
We all live in environments
562
00:48:27,863 --> 00:48:30,699
where there is some source of energy
that we can tap into.
563
00:48:30,825 --> 00:48:33,577
There's energy, there's power
all around us.
564
00:48:39,208 --> 00:48:42,378
And we need to start looking at
565
00:48:42,503 --> 00:48:47,299
these natural sources of energy
that don't have that negative impact.
566
00:48:53,973 --> 00:48:57,768
We have more energy
than we '1! Ever know what to do with.
567
00:48:57,893 --> 00:48:59,270
We can power the whole world
568
00:48:59,395 --> 00:49:04,733
with just a fraction of the solar and wind
that we get every year - a fraction of it!
569
00:49:12,366 --> 00:49:15,077
"NXALL". We're not going to start
needing less power any time soon.
570
00:49:15,202 --> 00:49:18,414
We're just going to have to shift
how we generate that power
571
00:49:18,539 --> 00:49:21,750
from non-renewables to renewables.
572
00:49:28,174 --> 00:49:29,550
Volcanic heat.
573
00:49:30,718 --> 00:49:33,012
So far, we've only tapped
574
00:49:33,137 --> 00:49:36,015
some 7% of its global potential.
575
00:49:38,434 --> 00:49:40,603
Or the wind in our skies.
576
00:49:42,188 --> 00:49:44,064
That could provide
577
00:49:44,190 --> 00:49:47,151
30% of our energy by 2050.
578
00:49:50,696 --> 00:49:53,115
And the power of the sun,
579
00:49:53,240 --> 00:49:56,660
which is virtually unlimited.
580
00:49:58,412 --> 00:50:02,458
In areas where most life
struggles to survive...
581
00:50:04,001 --> 00:50:09,173
there is plenty of space
to gather the maximum solar energy.
582
00:50:11,550 --> 00:50:18,015
The northern Sahara, home to the world's
largest concentrated solar power plant.
583
00:50:22,603 --> 00:50:24,939
Here, innovative technology
584
00:50:25,064 --> 00:50:28,359
is using mirrors
to superheat a special liquid
585
00:50:28,484 --> 00:50:33,030
to around 400 degrees Celsius.
586
00:50:33,155 --> 00:50:35,491
This heat is then stored in molten salt,
587
00:50:35,616 --> 00:50:40,704
allowing something not possible before,
588
00:50:40,829 --> 00:50:46,126
the ability to power steam turbines
with the sun's energy during the night.
589
00:50:47,294 --> 00:50:50,923
It creates green electricity
24 hours a day,
590
00:50:51,048 --> 00:50:54,301
feeding Morocco's growing energy needs.
591
00:50:56,303 --> 00:50:59,056
And it has plans to supply Europe.
592
00:51:00,432 --> 00:51:03,227
We need to make
enormous shifts in our society.
593
00:51:03,352 --> 00:51:05,229
This is starting,
594
00:51:05,354 --> 00:51:07,439
but it's happening just in small places.
595
00:51:07,565 --> 00:51:11,569
It needs to happen everywhere,
and it needs to happen much, much faster.
596
00:51:11,694 --> 00:51:13,779
There's really no excuse.
597
00:51:13,904 --> 00:51:15,906
The Earth has all of the power we need.
598
00:51:17,700 --> 00:51:20,035
Our mission is not
growth, growth, growth,
599
00:51:20,160 --> 00:51:22,037
but sustainability,
600
00:51:22,162 --> 00:51:27,334
and that our responsibility
is to steward this planet.
601
00:51:27,459 --> 00:51:28,586
That's the mission at hand.
602
00:51:31,130 --> 00:51:35,968
But is this transition to a
low-carbon society happening fast enough?
603
00:51:42,224 --> 00:51:46,186
In 2015, 195 of the world's nations
604
00:51:46,312 --> 00:51:50,858
pledged to reduce
their carbon dioxide emissions.
605
00:51:54,028 --> 00:51:56,655
To avoid planetary disaster,
606
00:51:56,780 --> 00:52:02,494
the goal was to limit the warming
of the Earth to well below two degrees.
607
00:52:04,163 --> 00:52:06,206
Together, citizens of the world,
608
00:52:06,332 --> 00:52:10,002
we will work to save our planet
from ourselves.
609
00:52:12,796 --> 00:52:17,509
"BARACK OBAMA". Today's a historic day
in the fight to protect our planet.
610
00:52:17,635 --> 00:52:20,596
You'll either be
lauded by future generations...
611
00:52:22,097 --> 00:52:23,724
or vilified by them.
612
00:52:27,269 --> 00:52:29,438
To get an accurate reading
613
00:52:29,563 --> 00:52:31,649
of CO2 levels in the Earth's atmosphere,
614
00:52:31,774 --> 00:52:35,944
you must be far away from
the pollution of the cities.
615
00:52:36,070 --> 00:52:38,364
So in the heart of the Amazon,
616
00:52:38,489 --> 00:52:44,453
they built a 325-metre tower
to do just that.
617
00:52:44,578 --> 00:52:50,250
It's one of a number of towers
around the planet collecting vital data,
618
00:52:50,376 --> 00:52:52,961
and the news is not good.
619
00:52:53,087 --> 00:52:55,923
This year, CO2 levels in the atmosphere
620
00:52:56,048 --> 00:53:00,302
went up yet again,
hitting another record high.
621
00:53:05,516 --> 00:53:08,394
I think we are in a crisis.
I'm not going to mince my words.
622
00:53:08,519 --> 00:53:10,354
We are in a crisis right now.
623
00:53:10,479 --> 00:53:14,149
We are pushing the equilibrium
that the planet used to be in
624
00:53:14,274 --> 00:53:16,568
in a way that may be unrecoverable.
625
00:53:19,488 --> 00:53:21,365
Ana' what the scientists
are telling us is,
626
00:53:21,490 --> 00:53:25,869
we will face a runaway cascade
of environmental events
627
00:53:25,994 --> 00:53:30,708
feeding off each other,
taking us into an unknown abyss
628
00:53:30,833 --> 00:53:34,920
that could lead to a very quick mass
extinction of much of life on this Earth
629
00:53:35,045 --> 00:53:37,256
in a very, very short period of time.
630
00:53:39,466 --> 00:53:41,885
Species are becoming extinct
631
00:53:42,010 --> 00:53:45,889
around one hundred times faster
than the normal rate.
632
00:53:46,014 --> 00:53:51,937
So rapid is the loss that zoos around
the world are taking drastic action.
633
00:53:53,814 --> 00:53:58,485
They're collecting DNA
from endangered species to build
634
00:53:58,610 --> 00:54:00,988
a genetic store of life
before they go extinct.
635
00:54:03,198 --> 00:54:07,411
At Edinburgh Zoo, a health check
on a Diana monkey
636
00:54:07,536 --> 00:54:08,787
presents a valuable opportunity
637
00:54:08,912 --> 00:54:14,793
to collect a sample for
the European network of biobanks.
638
00:54:19,506 --> 00:54:25,053
We really feel the pressure
to bank as many species as we can,
639
00:54:25,179 --> 00:54:29,349
as fast as we can, before it's too late.
640
00:54:29,475 --> 00:54:32,311
Martys Houck at San Diego Zoo
641
00:54:32,436 --> 00:54:36,482
receives DNA samples
from all over the world.
642
00:54:38,108 --> 00:54:41,236
She's taking them to a secure vault.
643
00:54:45,073 --> 00:54:48,869
It's known as the Frozen Zoo.
644
00:54:48,994 --> 00:54:50,871
It's hard to imagine,
645
00:54:50,996 --> 00:54:53,957
but there's probably
more vertebrate life in that room
646
00:54:54,082 --> 00:54:55,918
than anywhere else on the planet.
647
00:55:00,172 --> 00:55:03,467
We get samples every day.
It might be a tiger,
648
00:55:03,592 --> 00:55:07,221
it might be a bear,
it might be a rare reptile.
649
00:55:08,847 --> 00:55:14,186
Right now, we have over 10,000
individuals represented.
650
00:55:19,107 --> 00:55:21,902
The living cells
of our world's rarest animals
651
00:55:22,027 --> 00:55:26,532
are being stored here
at minus 200 degrees Celsius...
652
00:55:28,742 --> 00:55:33,080
keeping their DNA viable indefinitely,
653
00:55:33,205 --> 00:55:35,290
just in case the worst happens.
654
00:55:37,376 --> 00:55:41,213
There are multiple frozen zoos
like this around the world,
655
00:55:41,338 --> 00:55:43,590
and with extinction rates so high,
656
00:55:43,715 --> 00:55:47,219
they might be needed
sooner than we thought.
657
00:55:51,306 --> 00:55:54,142
I hope that we never have to see
658
00:55:54,268 --> 00:55:57,688
extinction of some of
these amazing species.
659
00:56:01,316 --> 00:56:03,902
But if we do, the samples
in the Frozen Zoo
660
00:56:04,027 --> 00:56:07,906
might be the hope for
bringing them back, so that...
661
00:56:08,031 --> 00:56:10,826
our children and grandchildren
662
00:56:10,951 --> 00:56:13,287
could once again
663
00:56:13,412 --> 00:56:15,998
see the actual animals.
664
00:56:16,123 --> 00:56:20,669
Not knowing what the planet
will be like when I'm an adult,
665
00:56:20,794 --> 00:56:23,255
not knowing whether it will be
capable of sustaining life,
666
00:56:23,380 --> 00:56:26,383
that is a terrifying thing to face.
667
00:56:30,596 --> 00:56:32,598
I think the planet
that I've been born into
668
00:56:32,723 --> 00:56:35,058
is the most beautiful place
that I could ever imagine.
669
00:56:35,183 --> 00:56:38,312
It's full of amazing wildlife...
670
00:56:38,437 --> 00:56:41,523
and us - humans are incredible.
671
00:56:43,734 --> 00:56:48,322
But we seem to forget that the place
that we live in is finite
672
00:56:48,447 --> 00:56:53,118
and very vulnerable, and it seems
to be dying before our eyes.
673
00:56:59,833 --> 00:57:03,754
Since the age of ten, I've been
hearing about our warming world,
674
00:57:03,879 --> 00:57:05,559
but nothing was really done at that time -
675
00:57:05,631 --> 00:57:08,425
all I observed at that time
is sort of mass apathy.
676
00:57:12,262 --> 00:57:14,389
But what is positive is that the youth
677
00:57:14,514 --> 00:57:16,224
are standing up and are taking leadership.
678
00:57:16,350 --> 00:57:18,060
Save our planet!
679
00:57:18,185 --> 00:57:20,270
Save our planet!
680
00:57:20,395 --> 00:57:22,314
Save our planet!
681
00:57:22,439 --> 00:57:23,774
We need more people to care.
682
00:57:23,899 --> 00:57:26,610
We need more people
to look at the facts and say,
683
00:57:26,735 --> 00:57:28,570
"I will do something about this."
684
00:57:31,156 --> 00:57:33,200
- Whose future?
- Our future!
685
00:57:33,325 --> 00:57:34,952
- Whose planet?
- Our planet!
686
00:57:35,077 --> 00:57:36,077
Whose future?
687
00:57:36,161 --> 00:57:40,791
50 we need to think about
how we interact with the natural world.
688
00:57:40,916 --> 00:57:43,085
We need to view it not as a commodity
689
00:57:43,210 --> 00:57:46,088
but as a system that we are a part of...
690
00:57:55,514 --> 00:57:58,183
because we are inextricably linked
691
00:57:58,308 --> 00:58:00,727
to the natural world,
and whatever happens
692
00:58:00,852 --> 00:58:02,604
to the oceans,
693
00:58:02,729 --> 00:58:05,607
whatever happens to the forests,
694
00:58:05,732 --> 00:58:08,819
whatever happens to the deserts,
that will come back
695
00:58:08,944 --> 00:58:10,779
and it will happen to us.
696
00:58:25,168 --> 00:58:28,547
Right now, we have
the capacity and knowledge
697
00:58:28,672 --> 00:58:31,091
to stop the damage we are doing.
698
00:58:33,218 --> 00:58:35,095
But what we don't have
699
00:58:35,220 --> 00:58:36,888
is time.
700
00:58:38,432 --> 00:58:41,184
My inspiration and hope for the future
701
00:58:41,309 --> 00:58:45,230
lies with the next generation.
702
00:58:45,355 --> 00:58:50,152
But we all have a responsibility
to reduce our carbon footprints,
703
00:58:50,277 --> 00:58:52,946
harness the forces of nature
for our energy
704
00:58:53,071 --> 00:58:56,116
and protect the natural world.
705
00:58:56,241 --> 00:59:01,538
The survival of humanity and our fellow
creatures on Earth depends upon it.
706
00:59:03,123 --> 00:59:08,128
Do you want to be the last generation that
signed the death certificate of humanity?
707
00:59:08,253 --> 00:59:11,840
Do you want to be the generation
that sees the last elephant killed?
708
00:59:11,965 --> 00:59:15,761
Do you want to be the generation that sees
the last fish fished out of the sea?
709
00:59:15,886 --> 00:59:19,431
Or do you want to be the generation
and the individuals that turned it around?
710
00:59:19,556 --> 00:59:22,851
This is the single most serious moment
711
00:59:22,976 --> 00:59:28,148
in the 200,000 years
that our species has been on this Earth.
712
00:59:28,273 --> 00:59:30,025
I see reason to hope.
713
00:59:31,109 --> 00:59:33,445
And I think we can.
714
00:59:33,570 --> 00:59:38,116
I think we, humans, we are
incredibly intelligent animals,
715
00:59:38,241 --> 00:59:39,451
and we can,
716
00:59:39,576 --> 00:59:40,994
and we will,
717
00:59:41,119 --> 00:59:43,038
if we set our minds to it.
