1
00:00:07,257 --> 00:00:10,978
Satellite cameras can now look down
on every part of our planet...
2
00:00:16,600 --> 00:00:19,399
revolutionising the view of our home.
3
00:00:25,400 --> 00:00:29,325
By combining images taken over days...
4
00:00:32,241 --> 00:00:33,709
weeks...
5
00:00:35,661 --> 00:00:37,459
and years...
6
00:00:40,207 --> 00:00:43,256
we can see Planet Earth change.
7
00:00:50,634 --> 00:00:56,437
From space, we can watch cities grow...
8
00:00:58,392 --> 00:01:02,067
Earth's natural resources shrink...
9
00:01:08,026 --> 00:01:11,530
and the weather become more extreme.
10
00:01:19,329 --> 00:01:21,548
As we alter the surface
of the planet...
11
00:01:23,292 --> 00:01:27,138
faster than at any time
in human history...
12
00:01:31,174 --> 00:01:36,431
this new perspective allows us
to track the speed of this change...
13
00:01:40,809 --> 00:01:43,938
to see the impact of our actions...
14
00:01:48,650 --> 00:01:53,406
and inspire us
to look after our fragile home.
15
00:02:22,559 --> 00:02:26,860
Humans now inhabit
every landmass on the planet.
16
00:02:29,399 --> 00:02:34,371
And the extent of our colonisation
is most obvious at night.
17
00:02:39,785 --> 00:02:42,413
Scientists have combined images
18
00:02:42,537 --> 00:02:47,008
to reveal a detailed view
of the entire globe at night...
19
00:02:56,927 --> 00:02:58,679
our cities and towns...
20
00:03:00,263 --> 00:03:02,357
reaching out across its surface.
21
00:03:19,282 --> 00:03:22,536
Using images taken over years,
22
00:03:22,661 --> 00:03:27,838
we can see just how fast
these cities are growing.
23
00:03:54,443 --> 00:03:56,741
In the last 40 years,
24
00:03:56,820 --> 00:04:00,324
Las Vegas has tripled in size...
25
00:04:04,494 --> 00:04:08,874
its suburbs sprawling
into the Nevada Desert.
26
00:04:13,920 --> 00:04:18,642
Tokyo is now home to 38 million.
27
00:04:24,765 --> 00:04:28,110
More people than any other city
on Earth.
28
00:04:34,191 --> 00:04:36,535
And, in just 35 years...
29
00:04:38,028 --> 00:04:41,157
the small fishing village
of Shenzhen in China...
30
00:04:42,824 --> 00:04:44,701
has grown to a modern city...
31
00:04:46,453 --> 00:04:47,500
of ten million.
32
00:04:54,294 --> 00:04:57,468
It has joined with
nine neighbouring cities,
33
00:04:57,589 --> 00:05:01,219
creating one giant megatropolis...
34
00:05:05,180 --> 00:05:08,559
home to more than 60 million people...
35
00:05:12,979 --> 00:05:16,108
across more than
5,000 square kilometres.
36
00:05:28,578 --> 00:05:30,626
As new land is claimed each day...
37
00:05:33,041 --> 00:05:35,294
nature is being pushed out.
38
00:05:45,095 --> 00:05:46,847
From above...
39
00:05:48,056 --> 00:05:53,563
India's streets are a densely packed
maze of grey concrete.
40
00:06:01,528 --> 00:06:06,204
But zoom in over Chennai,
one of India's largest cities...
41
00:06:07,951 --> 00:06:11,797
and we can see
a flash of bright green.
42
00:06:22,716 --> 00:06:25,139
Wild pa ra keets.
43
00:06:33,101 --> 00:06:38,699
In this ever-sprawling city,
one man has made room for wildlife.
44
00:06:41,067 --> 00:06:46,415
15 years ago, Joseph Sekar
saw a pair of parakeets
45
00:06:46,531 --> 00:06:49,751
struggling to find food
in the city streets.
46
00:06:56,207 --> 00:06:57,800
He put out rice for the birds.
47
00:07:03,131 --> 00:07:05,475
Others came,
48
00:07:05,592 --> 00:07:08,596
so each day he put out even more.
49
00:07:17,646 --> 00:07:20,650
Every day, he and his granddaughters
50
00:07:20,774 --> 00:07:26,122
turn his rooftop
into a giant bird table...
51
00:07:28,657 --> 00:07:31,001
awaiting the arrival...
52
00:07:32,577 --> 00:07:35,672
of 4,000 birds.
53
00:08:29,426 --> 00:08:33,522
Joseph spends nearly 50% of his income
on feeding the parakeets.
54
00:08:56,661 --> 00:09:01,292
They come twice a day, without fail.
55
00:09:05,545 --> 00:09:09,300
Joseph has not only given
a lifeline to these birds
56
00:09:09,382 --> 00:09:11,134
when they needed it most...
57
00:09:13,386 --> 00:09:18,768
he has brought a little bit of nature
back into the city streets.
58
00:09:47,962 --> 00:09:51,387
In a world where nature
is being pushed out...
59
00:09:53,176 --> 00:09:57,807
“Joseph is supporting
a whole population of animals...
60
00:10:03,728 --> 00:10:07,153
showing that one person in five million
61
00:10:07,273 --> 00:10:09,367
can make a huge difference.
62
00:10:31,089 --> 00:10:34,719
As the planet's urban landscapes
grow by the day...
63
00:10:36,094 --> 00:10:40,395
its most important wild spaces
are shrinking.
64
00:10:50,900 --> 00:10:56,122
In South America,
trees are cleared for farming.
65
00:11:11,754 --> 00:11:18,512
In the Amazon, small patches of green,
protected by local tribes...
66
00:11:20,096 --> 00:11:23,942
are all that remain
of a once-great forest.
67
00:11:31,357 --> 00:11:34,327
And on the island of Madagascar,
68
00:11:34,444 --> 00:11:36,947
images taken over 3O years...
69
00:11:38,406 --> 00:11:42,502
show it has lost almost 80%
of its original forest.
70
00:11:48,124 --> 00:11:52,504
With so few trees left
to hold the soil in place,
71
00:11:52,629 --> 00:11:57,635
the red earth now runs into the rivers
and out into the ocean.
72
00:12:02,931 --> 00:12:06,435
It looks like Madagascar is bleeding.
73
00:12:19,781 --> 00:12:21,283
The islands of Indonesia.
74
00:12:23,952 --> 00:12:26,250
An area of thick rainforest...
75
00:12:31,251 --> 00:12:34,471
home to thousands
of plant and animal species.
76
00:12:36,589 --> 00:12:40,093
But the view from space
shows it disappear.
77
00:12:47,892 --> 00:12:53,444
All over Indonesia,
swathes of forest are vanishing.
78
00:13:00,071 --> 00:13:05,498
And it's having a devastating impact
on one species in particular.
79
00:13:28,558 --> 00:13:31,277
This young Sumatran orangutan
80
00:13:31,394 --> 00:13:35,024
lives with her mother
in the forest canopy.
81
00:13:56,711 --> 00:14:00,011
At nearly three years old,
82
00:14:00,131 --> 00:14:04,011
she's still learning what's safe to eat
and what isn't.
83
00:14:10,975 --> 00:14:14,775
There are over 300 different types
of edible plants in the forest...
84
00:14:16,230 --> 00:14:19,780
but each fruit at different times.
85
00:14:21,527 --> 00:14:24,997
Finding food here isn't easy.
86
00:14:26,282 --> 00:14:29,286
She must rely on
her mother's expert knowledge.
87
00:14:38,878 --> 00:14:43,850
The pair can travel for up to
three kilometres a day foraging for food.
88
00:14:44,926 --> 00:14:49,352
Her mother knows the location
of each and every tree in her territory.
89
00:14:51,265 --> 00:14:56,146
Durian fruit, full of fats and vitamins,
are a favourite.
90
00:15:00,066 --> 00:15:03,036
Their smell tells her
if they're ready to eat.
91
00:15:05,780 --> 00:15:07,748
Every day is a lesson.
92
00:15:23,464 --> 00:15:26,138
It will be three more years
93
00:15:26,259 --> 00:15:29,763
before this young female
has learned enough to go it alone.
94
00:15:30,930 --> 00:15:34,104
But with orangutan habitat under threat,
95
00:15:34,183 --> 00:15:37,608
finding enough food
is becoming more difficult.
96
00:15:38,688 --> 00:15:41,862
She may not survive that long.
97
00:15:49,740 --> 00:15:55,372
This forest is home to the highest
concentration of orangutans on the planet.
98
00:15:59,083 --> 00:16:02,087
But as the satellite
moves across the landscape...
99
00:16:03,671 --> 00:16:06,265
the forest disappears.
100
00:16:13,556 --> 00:16:16,651
The last patches
of the orangutans' habitat...
101
00:16:19,353 --> 00:16:23,984
are surrounded by ordered fields.
102
00:16:30,448 --> 00:16:32,371
Row after row...
103
00:16:34,243 --> 00:16:36,291
of palm oil trees.
104
00:16:45,421 --> 00:16:49,471
Nuts from the trees are made into oil
105
00:16:49,592 --> 00:16:54,974
that's found in about half of all
the products on our supermarket shelves.
106
00:16:56,057 --> 00:17:00,233
From toothpaste to biscuits...
107
00:17:00,353 --> 00:17:02,981
lipstick to soap.
108
00:17:18,371 --> 00:17:20,123
In the last 20 years,
109
00:17:20,248 --> 00:17:23,502
orangutans have lost 80%
of their forest home.
110
00:17:28,297 --> 00:17:32,097
The scale and speed
of deforestation here
111
00:17:32,218 --> 00:17:35,188
makes it almost impossible to control.
112
00:17:40,309 --> 00:17:44,530
But now satellites can help.
113
00:17:46,107 --> 00:17:48,701
They can monitor tree loss in real time...
114
00:17:50,236 --> 00:17:53,661
revolutionising the fight
against illegal activity...
115
00:17:55,825 --> 00:18:00,376
allowing authorities to keep watch
on remote forests...
116
00:18:01,497 --> 00:18:04,467
and respond to protect them faster.
117
00:18:18,889 --> 00:18:22,610
It's not only forests
the humans are exploiting.
118
00:18:24,687 --> 00:18:31,320
We've found ways to use natural resources
across the planet.
119
00:18:40,036 --> 00:18:42,755
A mine fans out in Germany...
120
00:18:44,373 --> 00:18:48,924
producing 30 million tonnes
of brown coal a year
121
00:18:49,045 --> 00:18:50,922
to fuel electric power stations.
122
00:18:55,301 --> 00:18:58,931
In Chile, islands of blue
123
00:18:59,055 --> 00:19:00,978
appear in a vast salt flat.
124
00:19:04,852 --> 00:19:08,902
These evaporation ponds
concentrate lithium -
125
00:19:08,981 --> 00:19:12,781
to be made into batteries
for our mobile phones.
126
00:19:16,739 --> 00:19:19,367
In the deserts of Saudi Arabia,
127
00:19:19,492 --> 00:19:22,211
circles appear in the sand.
128
00:19:24,455 --> 00:19:28,676
Water pumped from one kilometre
below the Earth's surface
129
00:19:28,793 --> 00:19:30,670
is used to feed crops.
130
00:19:39,387 --> 00:19:43,517
And as we use Earth's natural resources
to fuel our industries...
131
00:19:45,101 --> 00:19:47,695
we leave our rubbish behind.
132
00:19:50,981 --> 00:19:55,612
Thousands of old aircraft
litter the Arizona desert.
133
00:20:01,325 --> 00:20:05,330
Hundreds of ships
line the coast of Bangladesh...
134
00:20:06,539 --> 00:20:08,633
waiting to be dismantled.
135
00:20:12,795 --> 00:20:17,141
And in Kuwait, a black patchwork
in the sand.
136
00:20:19,301 --> 00:20:23,556
Millions of used car tyres
left discarded.
137
00:20:30,104 --> 00:20:33,028
The waste products
of almost everything we make...
138
00:20:35,484 --> 00:20:36,736
".8 re gases.
139
00:20:42,116 --> 00:20:44,790
They rise into the atmosphere,
140
00:20:44,910 --> 00:20:47,254
where they become trapped,
141
00:20:47,371 --> 00:20:50,545
and absorb heat from the Earth below,
142
00:20:50,624 --> 00:20:52,752
making the planet hotter.
143
00:20:56,714 --> 00:20:58,682
In the last hundred years,
144
00:20:58,799 --> 00:21:01,848
our planet has warmed
by almost one degree Celsius...
145
00:21:03,512 --> 00:21:08,109
enough to dramatically affect
some of our greatest natural landscapes.
146
00:21:13,522 --> 00:21:15,274
Glaciers.
147
00:21:18,194 --> 00:21:19,787
Huge bodies of ice.
148
00:21:25,117 --> 00:21:29,497
In Alaska, Bear Glacier runs for
20 kilometres down the valley...
149
00:21:31,707 --> 00:21:35,086
before it breaks up
where it meets the water.
150
00:21:43,552 --> 00:21:48,149
In real time, glaciers can move so slowly
151
00:21:48,224 --> 00:21:49,771
they almost appear static.
152
00:22:01,737 --> 00:22:06,493
But by combining satellite images
taken over yea rs,
153
00:22:06,617 --> 00:22:08,961
we can see the ice retreating.
154
00:22:14,500 --> 00:22:16,673
Over 30 years...
155
00:22:18,629 --> 00:22:22,679
12 miles of ice is lost
from Alaska's Columbia Glacier.
156
00:22:32,309 --> 00:22:35,483
Mountain glaciers
are also under threat.
157
00:22:42,194 --> 00:22:47,246
In the centre of Ecuador,
South America, lies Chimborazo.
158
00:22:53,998 --> 00:22:58,720
At more than 6,000 metres,
it is the country's highest mountain.
159
00:23:05,885 --> 00:23:10,766
For millennia, its peak has been
covered in snow and ice.
160
00:23:17,563 --> 00:23:19,736
But in the past three decades,
161
00:23:19,857 --> 00:23:23,157
the view from space has started to change.
162
00:23:25,696 --> 00:23:30,668
Chimborazo is losing its ice.
163
00:23:38,959 --> 00:23:43,840
One man living in its foothills
knows this only too well.
164
00:24:10,658 --> 00:24:13,411
Balthazar is an ice harvester.
165
00:24:16,830 --> 00:24:21,882
For generations, his family have collected
glacial ice from the mountain
166
00:24:22,002 --> 00:24:25,677
to sell to the towns and villages below.
167
00:24:55,160 --> 00:24:57,288
He used to be one of 40 working here.
168
00:25:05,546 --> 00:25:08,345
Now he's the very last one.
169
00:25:11,301 --> 00:25:13,144
As the glacier melts,
170
00:25:13,220 --> 00:25:17,396
he's had to climb higher and higher
to find the ice.
171
00:25:40,122 --> 00:25:41,715
On the top of the mountain,
172
00:25:41,832 --> 00:25:46,884
scientists use drones
to monitor the change in the depth of ice
173
00:25:47,004 --> 00:25:52,977
to calculate just how fast
Chimborazo's glaciers are retreating.
174
00:25:55,137 --> 00:25:58,016
But a drone can only go so high.
175
00:26:09,526 --> 00:26:12,530
Combining these images
with satellite data...
176
00:26:14,073 --> 00:26:15,996
reveals the whole picture.
177
00:26:19,703 --> 00:26:21,831
Since 1976,
178
00:26:21,955 --> 00:26:26,756
21% of Chimborazo's surface ice
has gone.
179
00:26:40,766 --> 00:26:44,066
Glaciers act as
the world's water towers...
180
00:26:47,523 --> 00:26:53,496
feeding the streams
and rivers which we rely on.
181
00:26:56,198 --> 00:26:58,542
If they dry UP.
182
00:26:58,659 --> 00:27:00,832
The effect could be severe.
183
00:27:11,088 --> 00:27:17,266
For Balthazar, this could be the end
of the only way of life he's ever known.
184
00:27:21,348 --> 00:27:22,691
In the old days,
185
00:27:22,808 --> 00:27:25,937
he delivered ice to towns
all over the region.
186
00:27:29,898 --> 00:27:34,369
But now he supplies
just a handful of local cafes...
187
00:27:39,783 --> 00:27:46,007
who, like him, believe that his ice
is the best money can buy.
188
00:28:12,524 --> 00:28:18,998
As the Earth's climate changes,
our weather becomes more unpredictable.
189
00:28:24,828 --> 00:28:28,207
Extremes of hot and cold
190
00:28:28,332 --> 00:28:31,711
are contributing
to dramatic weather events.
191
00:28:36,965 --> 00:28:38,433
In Africa...
192
00:28:41,261 --> 00:28:42,433
snow falls...
193
00:28:44,681 --> 00:28:46,683
in the Sahara Desert.
194
00:28:54,650 --> 00:28:58,530
In 2018, an unusually hot summer...
195
00:29:00,781 --> 00:29:04,035
turned the UK brown.
196
00:29:13,001 --> 00:29:17,928
While in Bolivia,
Lake Poopé has all but disappeared,
197
00:29:18,048 --> 00:29:21,348
partly due to severe drought.
198
00:29:30,852 --> 00:29:33,571
As global temperatures rise,
199
00:29:33,689 --> 00:29:37,535
water on the Earth's surface
evaporates faster...
200
00:29:38,902 --> 00:29:40,950
creating more clouds...
201
00:29:42,489 --> 00:29:44,207
and more storms.
202
00:29:51,456 --> 00:29:53,083
Look down over the ocean...
203
00:29:54,876 --> 00:29:57,345
and the clouds shift into shape.
204
00:30:03,760 --> 00:30:05,433
They begin to spiral...
205
00:30:07,097 --> 00:30:09,270
and race...
206
00:30:10,767 --> 00:30:13,737
picking up energy
as they spin across the ocean.
207
00:30:17,482 --> 00:30:18,654
Hurricanes.
208
00:30:26,241 --> 00:30:31,623
On average, one hurricane hits the Gulf
Coast of the United States every yea r.
209
00:30:37,461 --> 00:30:40,681
But beach-side property
is still highly sought after.
210
00:30:49,431 --> 00:30:51,479
And not just by holiday-makers.
211
00:31:01,610 --> 00:31:04,329
The beach mouse makes its home here.
212
00:31:18,251 --> 00:31:22,677
These dunes have been hit by
four hurricanes in the last 25 years.
213
00:31:25,133 --> 00:31:27,101
Just a few miles down the coast,
214
00:31:27,219 --> 00:31:30,473
an entire beach mouse population
was wiped out...
215
00:31:34,810 --> 00:31:36,733
and had to be reintroduced.
216
00:31:44,444 --> 00:31:49,666
At three weeks old, every young mouse
must leave the family nest...
217
00:31:50,867 --> 00:31:52,915
and establish their own territory.
218
00:31:57,958 --> 00:31:59,426
Starting with a burrow.
219
00:32:03,422 --> 00:32:06,221
There's little vegetation,
220
00:32:06,341 --> 00:32:07,684
barely any cover.
221
00:32:09,177 --> 00:32:11,521
A bolthole is essential.
222
00:32:22,607 --> 00:32:25,986
Like all real estate on this coastline,
223
00:32:26,111 --> 00:32:28,830
burrows are hot property.
224
00:32:39,082 --> 00:32:43,633
It might take several days
to find a place of his own.
225
00:32:46,673 --> 00:32:49,392
Every moment spent out here alone,
226
00:32:49,509 --> 00:32:51,557
he's vulnerable.
227
00:32:52,637 --> 00:32:54,935
And not just to predators.
228
00:32:57,642 --> 00:33:00,942
Over the dunes,
the skies are getting darker.
229
00:33:09,112 --> 00:33:11,661
Clouds are building.
230
00:33:14,242 --> 00:33:18,497
While cameras on the dunes
follow the weather as it changes...
231
00:33:20,749 --> 00:33:22,626
at the same time
232
00:33:22,751 --> 00:33:25,425
a satellite positioned
out over the Gulf...
233
00:33:28,757 --> 00:33:31,351
allows us to see what a mouse can't.
234
00:33:33,887 --> 00:33:37,562
800 kilometres away from the dunes,
235
00:33:37,682 --> 00:33:39,901
a hurricane has formed.
236
00:33:45,732 --> 00:33:48,736
Like all major storms,
it's given a name.
237
00:33:50,403 --> 00:33:51,575
Harvey.
238
00:33:57,202 --> 00:33:58,875
300 kilometres across...
239
00:34:00,205 --> 00:34:03,926
and with winds of
over 100 miles per hour,
240
00:34:04,042 --> 00:34:09,173
it's predicted that Harvey
will make land in just eight hours.
241
00:34:11,466 --> 00:34:12,934
To tell where it will hit,
242
00:34:13,051 --> 00:34:15,429
we can track its movement from satellite.
243
00:34:23,645 --> 00:34:27,366
As it reaches the coast,
it spins away from the dunes.
244
00:34:36,157 --> 00:34:38,080
The beach mice are safe.
245
00:34:44,249 --> 00:34:46,297
But where Harvey makes landfall...
246
00:34:47,544 --> 00:34:51,390
images reveal the aftermath
of devastating flooding...
247
00:34:54,134 --> 00:34:56,728
caused by
over 120 centimetres of rain.
248
00:35:01,600 --> 00:35:06,652
Harvey was the most powerful storm
to hit the US in 12 years.
249
00:35:14,696 --> 00:35:17,540
And the wettest in American history.
250
00:35:26,958 --> 00:35:30,007
But Harvey was just the beginning.
251
00:35:32,672 --> 00:35:35,300
Next came Irma,
252
00:35:35,383 --> 00:35:37,260
JOSQ
253
00:35:37,385 --> 00:35:38,682
and Katia...
254
00:35:40,388 --> 00:35:43,608
in one of the worst hurricane seasons
on record.
255
00:35:49,564 --> 00:35:52,033
It's predicted that
an ever-warming planet
256
00:35:52,150 --> 00:35:54,869
will produce more powerful storms.
257
00:35:56,404 --> 00:35:59,453
But with satellites
mapping the path of hurricanes,
258
00:35:59,574 --> 00:36:02,578
they can help us to prepare
for when they hit.
259
00:36:12,087 --> 00:36:14,806
It's not only hurricanes
that are increasing.
260
00:36:16,424 --> 00:36:20,019
Another weather event leaves
indelible marks on our planet.
261
00:36:22,931 --> 00:36:26,561
California. 2018.
262
00:36:30,105 --> 00:36:34,827
A huge burn mark covering
more than 1,400 square kilometres.
263
00:36:40,407 --> 00:36:43,877
These scars are found across America
every summer.
264
00:36:52,794 --> 00:36:54,671
And the view from space
265
00:36:54,796 --> 00:36:58,141
gives us a brand-new perspective
on one of their causes.
266
00:37:05,348 --> 00:37:08,101
Look down on the planet at night...
267
00:37:11,146 --> 00:37:14,366
and the globe crackles and sparks...
268
00:37:19,237 --> 00:37:23,208
each bright spot a strike of lightning.
269
00:37:28,163 --> 00:37:32,839
Our world is struck
up to 5O times every second.
270
00:37:43,261 --> 00:37:47,016
As the energy of each strike
hits the Earth's surface...
271
00:37:49,559 --> 00:37:51,106
they create deadly sparks.
272
00:38:02,071 --> 00:38:05,666
In North America,
more than 10,000 wildfires a year
273
00:38:05,742 --> 00:38:07,585
are caused by lightning.
274
00:38:15,210 --> 00:38:19,181
This number is increasing
as the climate changes,
275
00:38:19,297 --> 00:38:22,551
so these fires must be monitored.
276
00:38:47,700 --> 00:38:51,375
Usually I get up
at about six o'clock in the morning.
277
00:38:52,831 --> 00:38:55,425
I get up, have a cup of coffee...
278
00:38:58,419 --> 00:39:00,296
and then I'm ready to go.
279
00:39:07,095 --> 00:39:09,223
Every day of each summer,
280
00:39:09,347 --> 00:39:15,775
85-year-old Billy Ellis
climbs the 143 steps to his office.
281
00:39:29,325 --> 00:39:33,330
I get to the radio about 9.25.
282
00:39:34,497 --> 00:39:37,501
Hello, Dispatch,
this is Devil's Head Tower, in service.
283
00:39:39,586 --> 00:39:44,308
I'm a fire lookout, and I've been
doing it now for 33 summers.
284
00:39:55,268 --> 00:40:00,365
After a long hot summer,
the forest is tinder dry.
285
00:40:01,399 --> 00:40:04,573
Perfect conditions for a fire.
286
00:40:08,573 --> 00:40:11,998
I look... About every 15 minutes,
I take a look around.
287
00:40:13,953 --> 00:40:17,457
You can look for days
and never see anything.
288
00:40:19,709 --> 00:40:21,928
Then, all of a sudden, there it is.
289
00:40:23,129 --> 00:40:26,633
Hello, Dispatch, this is
Devil's Head Tower. We have a smoke.
290
00:40:38,061 --> 00:40:42,612
Within minutes, a smoke plume
can stretch across the horizon.
291
00:40:44,525 --> 00:40:48,075
Now the most effective way to track it...
292
00:40:49,781 --> 00:40:51,249
is from space.
293
00:40:53,910 --> 00:40:57,835
Cameras can follow a fire's path
in almost real time...
294
00:41:00,500 --> 00:41:06,257
observing the smoke to predict
its direction, size and speed...
295
00:41:09,550 --> 00:41:12,679
guiding those fighting it
to the heart of the blaze.
296
00:41:32,699 --> 00:41:34,793
Using satellite positioning,
297
00:41:34,909 --> 00:41:39,415
smoke jumpers can be on the ground
within seven minutes of a call.
298
00:41:44,877 --> 00:41:48,973
Wildfire can burn
at 1,200 degrees Celsius.
299
00:41:55,388 --> 00:41:58,642
To stop it, they create breaks
in the forest...
300
00:42:01,769 --> 00:42:03,863
taking away its fuel.
301
00:42:24,834 --> 00:42:28,054
As human actions
continue to warm the planet...
302
00:42:29,797 --> 00:42:33,392
more wildfires
tear across the Earth's surface.
303
00:42:37,180 --> 00:42:43,358
In 2018, California had one of the worst
wildfire seasons in history.
304
00:42:46,647 --> 00:42:52,825
Satellites followed as more than
5,000 fires raged across the state...
305
00:42:55,114 --> 00:42:58,243
including the Mendocino Complex Fire...
306
00:43:00,036 --> 00:43:02,880
one of California's
la rgest-ever wildfires.
307
00:43:10,088 --> 00:43:12,716
But even in the most devastated
landscapes...
308
00:43:15,384 --> 00:43:16,806
lies opportunity.
309
00:43:28,564 --> 00:43:31,989
Billy isn't the only lookout
in the forest.
310
00:43:33,986 --> 00:43:38,082
This wood-boring beetle
is also searching for smoke.
311
00:43:42,787 --> 00:43:48,169
Special sensors in his body detect it
from many kilometres away.
312
00:44:07,436 --> 00:44:11,657
This blackened branch is weaker -
313
00:44:11,774 --> 00:44:14,493
easier to bore into and feed on.
314
00:44:23,578 --> 00:44:25,296
And where insects go...
315
00:44:25,413 --> 00:44:27,211
birds follow.
316
00:44:30,293 --> 00:44:32,091
A black-backed woodpecker.
317
00:44:34,088 --> 00:44:38,264
Perfectly camouflaged
in burned forests.
318
00:44:41,888 --> 00:44:44,516
Beetle grubs are full of fat.
319
00:44:50,938 --> 00:44:53,282
Food for hungry chicks.
320
00:45:04,160 --> 00:45:06,333
Within six months of the fire,
321
00:45:06,454 --> 00:45:11,506
the woodpecker holes have new residents.
322
00:45:30,019 --> 00:45:32,989
And new trees take root.
323
00:45:41,781 --> 00:45:46,878
Infrared satellite images of this forest
show it turn from brown...
324
00:45:48,871 --> 00:45:49,997
to green...
325
00:45:51,207 --> 00:45:52,925
in just three years.
326
00:45:55,586 --> 00:46:01,264
Wildfire is essential
for healthy forest habitat.
327
00:46:02,551 --> 00:46:04,895
It has regenerated the trees
328
00:46:05,012 --> 00:46:08,562
and supported the species
that live in them for millennia.
329
00:46:10,559 --> 00:46:13,062
But as we continue to warm our planet,
330
00:46:13,187 --> 00:46:16,987
increasing the size
and severity of these fires,
331
00:46:17,108 --> 00:46:21,033
it becomes our responsibility
to keep them under control.
332
00:46:34,834 --> 00:46:40,261
Cameras in space are a powerful tool
with which to monitor our planet...
333
00:46:47,471 --> 00:46:49,769
revealing landscapes under threat.
334
00:46:51,976 --> 00:46:54,525
But satellites also capture images
335
00:46:54,645 --> 00:46:59,947
in parts of the world where we are trying
to restore the balance.
336
00:47:08,284 --> 00:47:10,378
Just off the east coast of England...
337
00:47:13,998 --> 00:47:16,501
white dots appear in the sea.
338
00:47:19,628 --> 00:47:23,929
One of the world's largest
offshore wind-farms,
339
00:47:24,050 --> 00:47:28,351
generating enough power a year
for half a million homes.
340
00:47:34,477 --> 00:47:38,198
In China, two giant pandas.
341
00:47:39,690 --> 00:47:45,288
Solar panels creating electricity
as a greener alternative to burning coal.
342
00:47:51,702 --> 00:47:54,376
And in Tanzania, Africa...
343
00:48:05,716 --> 00:48:08,310
this land was cleared for farming.
344
00:48:15,267 --> 00:48:18,146
But now the view has changed.
345
00:48:19,313 --> 00:48:20,314
Completely.
346
00:48:24,568 --> 00:48:26,787
Forest has regrown...
347
00:48:30,157 --> 00:48:35,755
a transformation helping
one of our most iconic species.
348
00:48:48,717 --> 00:48:50,765
Gombe Stream National Park.
349
00:49:00,354 --> 00:49:02,356
This is Salama...
350
00:49:05,025 --> 00:49:06,948
and her mother, Schweini.
351
00:49:10,197 --> 00:49:14,168
They're members of
the Kasakela community -
352
00:49:14,285 --> 00:49:16,708
a troop of over 90 chimpanzees...
353
00:49:19,957 --> 00:49:24,303
first studied by primatologist
Jane Goodall back in 1960.
354
00:49:30,885 --> 00:49:36,858
The family have been followed
almost every single day for 58 years.
355
00:49:41,562 --> 00:49:45,908
It's the longest-running study
of any animal on Earth.
356
00:49:50,821 --> 00:49:55,076
Their protected forest
is near the village of Kigalye.
357
00:50:00,789 --> 00:50:05,465
Here, local people cut down trees
to make space for farmland.
358
00:50:12,384 --> 00:50:15,228
But without the trees
holding the earth together,
359
00:50:15,304 --> 00:50:16,931
there were landslides...
360
00:50:23,187 --> 00:50:25,030
and flash floods...
361
00:50:29,527 --> 00:50:33,828
threatening the village,
and their neighbours.
362
00:50:42,081 --> 00:50:46,552
To survive, female chimpanzees
363
00:50:46,669 --> 00:50:49,263
need to mix with other troops,
364
00:50:49,380 --> 00:50:51,382
moving territory to find a mate.
365
00:50:57,513 --> 00:51:00,858
But deforestation isolated the community.
366
00:51:03,852 --> 00:51:07,482
Their forest had become an island.
367
00:51:19,159 --> 00:51:22,379
With both people and chimps suffering,
368
00:51:22,496 --> 00:51:26,296
the jane Goodall Institute
began to work with the village
369
00:51:26,417 --> 00:51:28,294
to replant the trees...
370
00:51:32,131 --> 00:51:36,682
and provide the locals with
sustainable ways to use the land.
371
00:51:41,932 --> 00:51:47,530
Emmanuel Mtiti and Lilian Pintea
372
00:51:47,646 --> 00:51:50,741
have been working on the project
for 18 years.
373
00:51:52,943 --> 00:51:54,820
And they've had a little help...
374
00:51:56,530 --> 00:51:58,407
from satellites.
375
00:52:06,248 --> 00:52:09,172
This is a recent image of the area.
376
00:52:12,588 --> 00:52:15,967
Even the finest details are visible.
377
00:52:31,690 --> 00:52:35,991
So let's go back to this.
378
00:52:36,111 --> 00:52:38,614
By comparing satellite images,
379
00:52:38,739 --> 00:52:42,539
the villagers can see
what a difference they've made.
380
00:53:07,976 --> 00:53:10,525
The forests have been regenerated.
381
00:53:15,901 --> 00:53:19,701
Land that was infertile
has been brought back to life.
382
00:53:26,704 --> 00:53:28,798
The landslides have stopped...
383
00:53:32,668 --> 00:53:35,387
and flash floods
are no longer a problem.
384
00:54:02,239 --> 00:54:05,368
And it's not just the people
who have benefitted.
385
00:54:16,462 --> 00:54:19,056
For the first time in decades...
386
00:54:20,716 --> 00:54:25,392
new chimpanzees have been seen
using the surrounding forests...
387
00:54:28,015 --> 00:54:29,767
to travel into the reserve.
388
00:54:34,271 --> 00:54:36,444
Potential new mates...
389
00:54:41,945 --> 00:54:46,667
and a bright future
for this iconic species.
390
00:54:51,538 --> 00:54:54,382
Here in this small corner
of the planet...
391
00:54:58,086 --> 00:55:01,636
conservationists and local people
392
00:55:01,757 --> 00:55:04,727
have shown just what a difference
can be made
393
00:55:04,843 --> 00:55:06,720
when we work together.
394
00:55:11,058 --> 00:55:15,029
A change so important
and so dramatic...
395
00:55:17,481 --> 00:55:20,781
that it can be seen from space.
396
00:55:39,086 --> 00:55:44,889
This perspective allows us
to see our home in a whole new way.
397
00:55:49,596 --> 00:55:55,148
Satellite cameras now help us
to health-check our planet...
398
00:55:58,981 --> 00:56:00,574
see where it is thriving...
399
00:56:06,029 --> 00:56:12,378
but, crucially, where we
are upsetting its fragile balance.
400
00:56:15,873 --> 00:56:21,380
We can find and follow
our most vulnerable species...
401
00:56:30,178 --> 00:56:31,771
and make new discoveries...
402
00:56:34,558 --> 00:56:38,233
in extraordinary landscapes...
403
00:56:43,901 --> 00:56:48,327
transforming our understanding
of the way Earth works...
404
00:56:51,658 --> 00:56:55,162
and our place within it.
405
00:56:59,041 --> 00:57:01,715
This powerful new tool
406
00:57:01,835 --> 00:57:04,964
helps us protect our unique
407
00:57:05,088 --> 00:57:07,136
and fragile planet.
