1
00:00:20,645 --> 00:00:22,772
Just 50 years ago,
2
00:00:23,440 --> 00:00:26,276
we finally ventured to the moon.
3
00:00:40,331 --> 00:00:45,795
For the very first time,
we looked back at our own planet.
4
00:00:53,344 --> 00:00:58,683
Since then, the human population
has more than doubled.
5
00:01:04,189 --> 00:01:08,610
This series will celebrate
the natural wonders that remain
6
00:01:09,569 --> 00:01:12,280
and reveal what we must preserve
7
00:01:12,655 --> 00:01:16,868
to ensure people and nature thrive.
8
00:01:34,552 --> 00:01:36,805
This is a tropical forest.
9
00:01:38,181 --> 00:01:39,599
A rain forest.
10
00:01:40,141 --> 00:01:42,310
The richest habitat on Earth.
11
00:01:44,938 --> 00:01:48,900
Exactly how many species
rain forests contain is unknown,
12
00:01:49,567 --> 00:01:51,528
but it runs into millions.
13
00:01:52,737 --> 00:01:54,948
And new ones are discovered every week.
14
00:02:00,578 --> 00:02:05,416
There are some, like this clouded leopard,
we still know virtually nothing about.
15
00:02:15,802 --> 00:02:19,222
Although they cover just seven percent
of the world's land area,
16
00:02:19,597 --> 00:02:23,726
jungles play a vital role
in the health of the planet.
17
00:02:42,203 --> 00:02:45,456
In the heart of Africa lies the Congo.
18
00:02:49,252 --> 00:02:53,923
It is our planet's youngest rain forest,
a mere 18,000 years old,
19
00:02:54,465 --> 00:02:58,261
and it's the jungle
with more big animals than any other.
20
00:03:17,322 --> 00:03:19,949
A family of lowland gorillas.
21
00:03:24,037 --> 00:03:27,165
They're led by this silverback,
the dominant male.
22
00:03:33,046 --> 00:03:36,049
He's as tall as a man,
but twice the weight.
23
00:03:37,634 --> 00:03:40,220
His family depend on him for survival.
24
00:03:44,224 --> 00:03:47,518
As their guardian,
he must keep a lookout for danger.
25
00:03:57,153 --> 00:04:01,115
A rival male might usurp him
and tear his family apart.
26
00:04:03,826 --> 00:04:07,705
But there is one threat
beyond his control.
27
00:04:10,166 --> 00:04:11,584
In the last 20 years,
28
00:04:11,834 --> 00:04:16,089
poaching for bushmeat has halved
the Congo's gorilla population.
29
00:04:29,060 --> 00:04:32,146
His kind are now critically endangered.
30
00:04:49,080 --> 00:04:53,167
It's only a forest elephant,
which needn't concern the silverback.
31
00:05:01,050 --> 00:05:04,887
But the elephant
has reason to be wary of poachers too.
32
00:05:08,474 --> 00:05:11,644
Their long straight tusks
are even more sought after
33
00:05:11,728 --> 00:05:14,022
than those of their grassland cousins.
34
00:05:22,113 --> 00:05:23,406
He follows paths
35
00:05:23,573 --> 00:05:26,326
made by generations of elephants
before him,
36
00:05:26,784 --> 00:05:28,119
searching for food.
37
00:05:34,375 --> 00:05:38,921
Like the elephant, the silverback's family
will travel several kilometers a day,
38
00:05:39,047 --> 00:05:41,007
looking for fruits and seeds.
39
00:05:45,970 --> 00:05:49,599
They and the elephants
are the gardeners of this jungle.
40
00:05:50,683 --> 00:05:52,268
The seed dispersers.
41
00:05:54,520 --> 00:05:56,272
And many of the trees here
42
00:05:56,356 --> 00:05:59,233
owe their existence
to these large animals.
43
00:06:05,948 --> 00:06:10,703
Here,
all paths eventually lead to Mbeli Bai.
44
00:06:18,586 --> 00:06:22,799
Open areas like this are a unique feature
of the Congo's jungles,
45
00:06:22,882 --> 00:06:26,552
and there are more than a hundred
dotted throughout the forest.
46
00:06:30,348 --> 00:06:35,269
Known as bais, these clearings attract
many of the jungle's inhabitants.
47
00:06:47,698 --> 00:06:50,743
The silverback
cautiously leads the way,
48
00:06:52,537 --> 00:06:54,539
but his family are close behind.
49
00:07:20,064 --> 00:07:24,235
The gorillas come to feed
on aquatic plants rich in salt,
50
00:07:24,694 --> 00:07:27,780
a mineral in short supply
inside the forest,
51
00:07:28,489 --> 00:07:30,324
but crucial to their survival.
52
00:07:43,588 --> 00:07:47,967
Elephants mine salts from the mud
using their trunks.
53
00:07:56,225 --> 00:07:58,936
Or just drink the mineral-enriched water.
54
00:08:06,444 --> 00:08:09,822
The silverback's family
are not the only gorillas here.
55
00:08:11,365 --> 00:08:14,577
Nearly 200 others also use this bai,
56
00:08:15,661 --> 00:08:18,748
as well as more than 530 elephants,
57
00:08:19,457 --> 00:08:22,126
a measure of Mbeli's importance.
58
00:08:29,175 --> 00:08:33,221
For the elephants,
the bais have another vital role.
59
00:08:37,141 --> 00:08:38,684
Most of their lives are spent
60
00:08:38,768 --> 00:08:41,979
roaming the vast forested interior
on their own,
61
00:08:43,064 --> 00:08:46,442
so it's only here
they get a chance to meet others.
62
00:08:55,284 --> 00:08:59,872
Unlike most of the Congo's other bais,
Mbeli is well protected,
63
00:09:00,081 --> 00:09:02,250
making it a refuge from poaching.
64
00:09:06,629 --> 00:09:10,132
It's only when they leave
that the danger returns.
65
00:09:14,011 --> 00:09:16,889
And as the Congo's main seed dispersers,
66
00:09:17,306 --> 00:09:21,352
the loss of its megafauna
could have a far-reaching impact
67
00:09:21,561 --> 00:09:26,232
on the future of our planet's
second-largest rain forest.
68
00:09:35,700 --> 00:09:37,326
Jungles may look the same,
69
00:09:37,660 --> 00:09:40,955
but each is home
to a unique cast of characters.
70
00:09:45,209 --> 00:09:48,754
New Guinea is the world's largest
jungle-covered island,
71
00:09:49,213 --> 00:09:51,716
and more than half
of its plants and animals
72
00:09:51,799 --> 00:09:54,176
are found nowhere else on Earth.
73
00:09:58,806 --> 00:10:02,810
Its turbulent geological past
has shaped this vast island
74
00:10:02,893 --> 00:10:06,981
into a dramatic landscape
of mountains and valleys.
75
00:10:11,527 --> 00:10:15,197
A process
that isolated one species from another.
76
00:10:19,076 --> 00:10:20,536
Separated in this way,
77
00:10:20,620 --> 00:10:24,123
New Guinea's animals
have become truly bizarre.
78
00:10:27,335 --> 00:10:29,879
The male twelve-wired bird-of-paradise
79
00:10:30,004 --> 00:10:33,924
is the only bird in the world
that has tail ornaments like this,
80
00:10:35,551 --> 00:10:39,138
used to tickle
the face of a prospective mate.
81
00:10:41,974 --> 00:10:43,934
From one crow-like ancestor,
82
00:10:44,060 --> 00:10:48,314
birds-of-paradise have evolved
into 40 different kinds.
83
00:10:50,524 --> 00:10:53,486
Every corner of this island
has its own version.
84
00:10:55,863 --> 00:10:59,659
Meet the black sicklebill
of New Guinea's highlands...
85
00:11:04,038 --> 00:11:07,875
...able to morph
into some very un-birdlike shapes.
86
00:11:16,050 --> 00:11:21,430
Each male bird-of-paradise
has a unique display for attracting mates,
87
00:11:22,431 --> 00:11:24,600
and none is more extraordinary
88
00:11:24,850 --> 00:11:28,062
than the one that takes place
on this stage.
89
00:11:33,359 --> 00:11:37,738
For the owner, a western parotia,
there's work to be done first.
90
00:11:41,242 --> 00:11:45,079
Every morning, he clears his court
of the night's fallen debris.
91
00:11:50,126 --> 00:11:53,879
It's a vital chore
if he wants to attract a mate.
92
00:11:56,882 --> 00:11:59,844
Females only visit the tidiest courts,
93
00:12:03,264 --> 00:12:06,559
so one rogue leaf might ruin his chances.
94
00:12:16,861 --> 00:12:17,861
Perfect.
95
00:12:19,238 --> 00:12:21,824
His obsessive housework pays off,
96
00:12:23,033 --> 00:12:25,536
and a female drops in for a closer look.
97
00:12:27,288 --> 00:12:29,832
Now is his chance to really impress,
98
00:12:30,916 --> 00:12:32,293
but it won't be easy.
99
00:12:34,170 --> 00:12:35,588
Females are very fussy,
100
00:12:36,130 --> 00:12:39,133
and she'll expect
his carefully choreographed routine
101
00:12:39,258 --> 00:12:40,258
to be faultless.
102
00:12:42,178 --> 00:12:44,138
He opens with a bow.
103
00:12:46,182 --> 00:12:48,851
Next, his blue eye must flash yellow.
104
00:12:52,521 --> 00:12:53,981
So far, so good.
105
00:12:55,941 --> 00:12:58,027
He has all the moves.
106
00:12:59,862 --> 00:13:01,155
Fancy footwork.
107
00:13:04,366 --> 00:13:05,910
The whirling dervish.
108
00:13:12,708 --> 00:13:15,836
The head plume shuffle, with spin.
109
00:13:18,923 --> 00:13:21,509
Her erect head feathers
and quivering wings
110
00:13:21,592 --> 00:13:23,511
are a very encouraging sign.
111
00:13:32,311 --> 00:13:35,689
His sidestep and head bob
look good from any angle,
112
00:13:37,233 --> 00:13:38,484
but his crowning glory
113
00:13:38,651 --> 00:13:41,987
can only be appreciated
from her perspective.
114
00:13:44,406 --> 00:13:45,406
Wait for it.
115
00:13:47,243 --> 00:13:50,454
There it is.
A flash of his iridescent throat patch.
116
00:13:53,624 --> 00:13:55,501
Her excitement grows.
117
00:14:12,685 --> 00:14:14,562
His performance has been a triumph,
118
00:14:17,523 --> 00:14:19,525
and he wins her approval.
119
00:14:27,908 --> 00:14:32,246
New Guinea's isolation
has created a unique variety of animals,
120
00:14:34,164 --> 00:14:37,543
but the age of a forest
has an even greater impact
121
00:14:37,626 --> 00:14:39,962
on the diversity of life it contains.
122
00:14:43,674 --> 00:14:46,385
The jungles of Borneo, in Southeast Asia,
123
00:14:46,677 --> 00:14:50,848
have grown here
for nearly 130 million years,
124
00:14:51,640 --> 00:14:54,059
making them the oldest on Earth.
125
00:14:59,648 --> 00:15:03,235
This limestone mountaintop
in Borneo's highlands
126
00:15:03,694 --> 00:15:05,654
was originally formed under the sea.
127
00:15:08,240 --> 00:15:12,036
Time and rain
has slowly shaped this jungle fortress
128
00:15:12,244 --> 00:15:14,747
into these 40-meter towers.
129
00:15:25,299 --> 00:15:29,261
The great age of this island's jungle
is best illustrated
130
00:15:29,511 --> 00:15:32,514
by one of the oldest predators on Earth.
131
00:15:43,067 --> 00:15:44,652
A velvet worm.
132
00:15:46,070 --> 00:15:49,323
Completely at home
on the humid forest floor.
133
00:15:53,035 --> 00:15:55,746
They've been here
since the age of the dinosaurs,
134
00:15:56,038 --> 00:15:58,999
and have remained virtually unchanged.
135
00:16:05,965 --> 00:16:10,052
It detects its insect prey
through vibration and touch.
136
00:16:11,804 --> 00:16:13,597
But with no turn of speed,
137
00:16:14,014 --> 00:16:17,017
how does it capture
these fleet-footed critters?
138
00:16:20,688 --> 00:16:22,898
The answer is stranger than fiction.
139
00:16:28,779 --> 00:16:30,072
Glue guns.
140
00:16:34,368 --> 00:16:36,412
The sticky slime hardens on impact,
141
00:16:38,247 --> 00:16:40,124
trapping the luckless insect.
142
00:16:41,542 --> 00:16:45,045
The velvet worm will inject the cockroach
with digestive saliva,
143
00:16:45,921 --> 00:16:48,507
and then suck out its insides.
144
00:16:55,556 --> 00:17:00,477
The high humidity of the forest floor
isn't just good for velvet worms.
145
00:17:06,400 --> 00:17:08,777
It's perfect for fungi, too,
146
00:17:10,654 --> 00:17:14,366
and Borneo's ancient jungles
are rich in species.
147
00:17:26,962 --> 00:17:28,797
By decomposing the dead,
148
00:17:29,423 --> 00:17:34,136
the slime molds and fungi
recycle scarce nutrients.
149
00:17:50,527 --> 00:17:55,949
Time has made Borneo's jungles
extraordinarily rich and diverse.
150
00:17:57,785 --> 00:18:00,454
Here, in just a few hectares of forest,
151
00:18:00,913 --> 00:18:04,917
there may be more kinds of plants
than in the whole of Europe,
152
00:18:08,629 --> 00:18:12,424
including
some of the most specialized on Earth.
153
00:18:18,847 --> 00:18:20,015
Over several weeks,
154
00:18:20,099 --> 00:18:25,145
these growing tips inflate
to form jugs or pitchers.
155
00:18:34,655 --> 00:18:38,075
There are 39 kinds of pitcher plant
in Borneo,
156
00:18:38,575 --> 00:18:41,078
and most are found nowhere else.
157
00:18:44,373 --> 00:18:49,753
To get the nutrients they need to survive,
pitcher plants rely on animals,
158
00:18:50,504 --> 00:18:52,548
often in surprising ways.
159
00:18:57,344 --> 00:19:02,266
This is the mountain treeshrew,
an animal found only in Borneo.
160
00:19:12,151 --> 00:19:15,779
Every morning, the treeshrew visits
his neighborhood pitchers.
161
00:19:17,114 --> 00:19:19,241
It depends on the sugary solution
162
00:19:19,366 --> 00:19:22,452
that exudes
from hairs on the pitcher's lid.
163
00:19:25,455 --> 00:19:28,750
When he's licked this lid dry,
he'll move to another.
164
00:19:31,712 --> 00:19:33,422
And then another.
165
00:19:38,635 --> 00:19:42,723
Eventually, all that sugar
can have only one result.
166
00:19:50,272 --> 00:19:54,568
In return for the free food,
the treeshrew leaves a gift.
167
00:19:56,069 --> 00:19:58,071
Fertilizer for the plant.
168
00:20:00,490 --> 00:20:03,368
All that's needed is an afternoon shower
169
00:20:03,452 --> 00:20:07,164
to flush the shrew poo
into the pitcher's bowl.
170
00:20:13,295 --> 00:20:17,090
Without these added nitrates,
the plant couldn't survive.
171
00:20:19,384 --> 00:20:24,431
And the quest for nutrients has led
some pitchers down a sinister path.
172
00:20:28,894 --> 00:20:30,854
A gracilis pitcher plant
173
00:20:31,230 --> 00:20:35,734
attracts ants to the underside of its lid
with drops of nectar.
174
00:20:37,819 --> 00:20:40,656
But what do the ants give in return?
175
00:20:43,909 --> 00:20:47,287
It's a story that also depends on rain.
176
00:20:50,082 --> 00:20:51,625
The force of the raindrops
177
00:20:51,708 --> 00:20:54,378
make it impossible
for the ants to hold on.
178
00:21:01,176 --> 00:21:05,222
It's the plant world's
only springboard trap.
179
00:21:06,890 --> 00:21:10,560
This pitcher plant
feeds on ant bodies.
180
00:21:18,443 --> 00:21:21,613
All pitcher plants
depend on animals for survival,
181
00:21:23,282 --> 00:21:26,868
and one has even gone into business
with a bat.
182
00:21:29,496 --> 00:21:32,624
The woolly bat finds hemsleyana pitchers
183
00:21:32,874 --> 00:21:38,338
because the plant's broad back wall
reflects the bat's ultrasound.
184
00:21:44,303 --> 00:21:48,348
The tube-like pitchers
are the perfect roosting site.
185
00:21:52,436 --> 00:21:55,230
The pitcher provides secure accommodation
186
00:21:55,689 --> 00:21:59,651
and the plant is enriched
by its guest's deposits.
187
00:22:04,072 --> 00:22:07,868
Relationships like these
have taken millions of years to evolve,
188
00:22:08,368 --> 00:22:11,246
but many could be gone in a decade.
189
00:22:14,916 --> 00:22:20,005
In the last 50 years,
Borneo has lost over half of its jungle.
190
00:22:23,550 --> 00:22:25,260
And it's even worse
191
00:22:25,344 --> 00:22:27,971
on the neighboring islands
of the Philippines.
192
00:22:30,307 --> 00:22:34,227
Here, 90 percent
of the primary rain forest has gone.
193
00:22:41,068 --> 00:22:46,490
What's left is the last refuge
for the world's rarest bird of prey.
194
00:22:47,616 --> 00:22:49,826
The mighty Philippines eagle.
195
00:22:56,958 --> 00:22:59,628
With just 400 pairs remaining,
196
00:22:59,920 --> 00:23:03,173
a chick on a nest is a very scarce sight.
197
00:23:07,344 --> 00:23:10,472
Scientists have tracked the mother
since she was a year old.
198
00:23:11,223 --> 00:23:14,643
Now aged ten, this is her first chick.
199
00:23:22,317 --> 00:23:26,029
It's four months old,
already nearly a meter tall,
200
00:23:26,822 --> 00:23:28,740
and increasingly confident.
201
00:23:31,493 --> 00:23:34,996
Although Mother still likes to give
a helping hand.
202
00:23:42,671 --> 00:23:45,215
The chick is very demanding.
203
00:23:48,802 --> 00:23:51,346
She expects regular food drops,
204
00:23:52,097 --> 00:23:56,935
but, like a toddler having a tantrum,
she doesn't want any help at mealtimes.
205
00:24:01,273 --> 00:24:04,025
Already, she's the same size as her father
206
00:24:04,484 --> 00:24:06,528
and too big to argue with.
207
00:24:08,530 --> 00:24:11,283
But if his youngster
is to take her next steps,
208
00:24:11,533 --> 00:24:14,744
he knows it's time for some tough love.
209
00:24:16,204 --> 00:24:19,249
From now on,
visits will be less frequent.
210
00:24:30,927 --> 00:24:34,764
The parents drop by
with an occasional food parcel,
211
00:24:37,642 --> 00:24:41,104
but a small fruit bat
isn't much to get excited about.
212
00:24:48,695 --> 00:24:49,779
It's confusing
213
00:24:49,863 --> 00:24:53,950
when your parents don't visit
as frequently as they once did.
214
00:25:04,920 --> 00:25:06,630
Every day, she calls,
215
00:25:08,298 --> 00:25:10,383
but no one is paying any attention.
216
00:25:15,639 --> 00:25:16,639
She's hungry,
217
00:25:17,974 --> 00:25:20,352
and all that's left are scraps.
218
00:25:26,274 --> 00:25:29,236
It's time to become a proper eagle.
219
00:25:34,241 --> 00:25:38,453
Flapping strengthens flight muscles
in two-meter wings.
220
00:25:43,124 --> 00:25:46,586
Wings that will be used
to carry off her hefty prey.
221
00:25:51,841 --> 00:25:54,803
Though that skill is still some time off.
222
00:25:59,975 --> 00:26:03,728
So far, she's never ventured
beyond the security of her nest.
223
00:26:08,984 --> 00:26:10,485
And with good reason.
224
00:26:15,532 --> 00:26:18,868
There's a 70-meter drop
to the forest floor.
225
00:26:24,082 --> 00:26:25,667
A fall would be fatal.
226
00:26:32,966 --> 00:26:37,053
It's a nervous moment,
but she must persevere.
227
00:26:39,556 --> 00:26:42,350
Right now, she's all toes and talons.
228
00:26:52,569 --> 00:26:58,325
Sudden gusts of wind are not helpful
when balancing over a death-defying drop,
229
00:27:00,952 --> 00:27:03,705
and the daily downpours
don't make it any easier.
230
00:27:14,257 --> 00:27:18,845
Every day, she gets a little stronger
and more confident.
231
00:27:25,101 --> 00:27:30,398
Then, the day comes when confidence
finally matches know-how.
232
00:27:48,249 --> 00:27:51,503
Now is the moment to reach for the sky.
233
00:28:00,470 --> 00:28:03,515
Her first ever flight from her nest tree.
234
00:28:07,227 --> 00:28:10,980
It'll be nearly a year
before she's fully independent.
235
00:28:13,066 --> 00:28:16,319
Then, her survival
will depend on finding a territory
236
00:28:16,903 --> 00:28:19,781
with large stretches of unspoilt jungle.
237
00:28:26,496 --> 00:28:28,456
In the Philippines' fragmented forest,
238
00:28:28,665 --> 00:28:32,669
there's just too little prey
for a supersized eagle.
239
00:28:36,756 --> 00:28:40,719
But there is one jungle
whose size is still legendary.
240
00:28:45,098 --> 00:28:49,144
The Amazon basin
is over 3,000 kilometers across
241
00:28:49,477 --> 00:28:53,732
and home to half of our planet's
remaining rain forest.
242
00:29:00,697 --> 00:29:04,743
But there are challenges for those
living in the Amazon's deep interior.
243
00:29:14,377 --> 00:29:16,087
Black spider monkeys,
244
00:29:17,630 --> 00:29:19,841
with eyes on a salt lick.
245
00:29:23,887 --> 00:29:27,932
Being so far from the sea,
salt is in short supply here,
246
00:29:28,683 --> 00:29:31,352
so a visit to a lick is essential.
247
00:29:36,191 --> 00:29:40,236
But first, they must be sure
there are no predators lurking below.
248
00:29:42,864 --> 00:29:45,450
A harmless agouti is a good sign.
249
00:29:54,334 --> 00:29:58,338
This is the only time a spider monkey
ever sets foot on the ground.
250
00:30:04,052 --> 00:30:05,887
And if you have your head in a hole,
251
00:30:07,597 --> 00:30:08,973
best to have a lookout.
252
00:30:11,726 --> 00:30:14,604
Monkeys can't survive
without these minerals,
253
00:30:15,855 --> 00:30:17,524
and predators know it.
254
00:30:22,946 --> 00:30:24,864
A warning from the lookout.
255
00:30:35,500 --> 00:30:37,168
It's not a false alarm.
256
00:30:41,548 --> 00:30:42,548
A jaguar.
257
00:30:44,676 --> 00:30:47,846
Rarely seen,
but the Amazon's top predator.
258
00:30:56,104 --> 00:30:59,607
With the jaguar gone, the monkeys return,
259
00:31:01,025 --> 00:31:02,527
but it's a risk.
260
00:31:03,194 --> 00:31:06,155
Nobody knows
when the predator will be back.
261
00:31:13,705 --> 00:31:18,126
It's not just spider monkeys
for whom fear must give way to need.
262
00:31:19,794 --> 00:31:23,965
In the Amazon, salt licks are as vital
as an oasis in a desert.
263
00:31:31,097 --> 00:31:33,182
Noises could be friend or foe,
264
00:31:33,266 --> 00:31:36,936
so every visitor
must remain poised for flight.
265
00:32:00,460 --> 00:32:01,961
It's a false alarm.
266
00:32:02,337 --> 00:32:04,505
Just the harmless agouti again.
267
00:32:10,094 --> 00:32:14,557
In the Amazon, every animal group
has more species than anywhere else.
268
00:32:17,644 --> 00:32:19,479
And that includes frogs.
269
00:32:22,941 --> 00:32:26,611
There are thought to be over a thousand
different kinds of them here,
270
00:32:30,615 --> 00:32:33,493
and new ones are still being discovered.
271
00:32:49,801 --> 00:32:52,971
Frogs are an indicator
of a healthy forest,
272
00:32:54,347 --> 00:32:59,727
but its most important residents
are the jungle's smallest inhabitants.
273
00:33:16,953 --> 00:33:21,833
There are thought to be over two million
kinds of insect in the Amazon.
274
00:33:23,501 --> 00:33:25,670
These are the most numerous.
275
00:33:30,842 --> 00:33:35,054
A colony of leafcutter ants
can run into the millions.
276
00:33:41,310 --> 00:33:45,356
Each colony is a superorganism
with a collective function...
277
00:33:46,607 --> 00:33:51,070
to gather leaves and carry them back
to their underground nests.
278
00:34:13,176 --> 00:34:15,595
Within the territory
of a leafcutter colony,
279
00:34:15,678 --> 00:34:21,684
as much as a fifth of all new plant growth
will be harvested by the ants.
280
00:34:23,519 --> 00:34:26,564
Slicing through leaves
with specialized mandibles,
281
00:34:26,856 --> 00:34:32,070
they produce high frequency vibrations,
which stiffens the leaf,
282
00:34:32,904 --> 00:34:34,280
making it easier to cut.
283
00:34:36,491 --> 00:34:41,162
Working together,
they can strip a tree bare in 24 hours.
284
00:34:52,090 --> 00:34:56,385
The trick is holding on to your leaf
as you fall.
285
00:35:01,140 --> 00:35:02,892
Easier said than done.
286
00:35:04,644 --> 00:35:08,022
But best not to return to the nest
empty-handed.
287
00:35:15,655 --> 00:35:19,075
A leafcutter colony
is like a mega-herbivore,
288
00:35:19,325 --> 00:35:21,828
not dissimilar
to an elephant in the Congo,
289
00:35:21,911 --> 00:35:25,998
and their impact on the ecosystem
is just as important.
290
00:35:28,709 --> 00:35:32,046
The ants follow scent trails
back to the nest,
291
00:35:35,383 --> 00:35:37,552
dodging unexpected obstacles.
292
00:35:42,056 --> 00:35:47,061
But to increase efficiency,
the ants keep their paths clear of debris.
293
00:36:04,495 --> 00:36:08,082
A leafcutter nest
can be up to eight meters deep
294
00:36:08,291 --> 00:36:11,419
and have thousands
of interconnected chambers.
295
00:36:15,089 --> 00:36:18,134
The workers
carry the freshly harvested leaves
296
00:36:18,342 --> 00:36:20,845
to special rooms for processing.
297
00:36:23,848 --> 00:36:28,686
The leaves are not food,
but used to create gardens of fungus,
298
00:36:28,769 --> 00:36:30,646
which they feed to their larvae.
299
00:36:35,693 --> 00:36:40,823
The success of the colony depends on
keeping their gardens disease-free.
300
00:36:42,033 --> 00:36:46,787
So, the ants have teamed up
with bacteria to help control pathogens,
301
00:36:46,954 --> 00:36:49,248
which would destroy their precious fungi.
302
00:36:53,377 --> 00:36:54,837
Scientists now believe
303
00:36:54,921 --> 00:36:59,300
these bacteria could provide
new solutions to human diseases.
304
00:37:03,221 --> 00:37:05,473
But as successful as these ants are,
305
00:37:05,681 --> 00:37:11,604
the rain forest's diversity depends on
no one species gaining the upper hand.
306
00:37:18,903 --> 00:37:21,572
Here,
ants don't have it all their own way.
307
00:37:25,034 --> 00:37:27,245
This one is behaving oddly.
308
00:37:32,708 --> 00:37:35,336
It seems compelled to climb upwards,
309
00:37:35,753 --> 00:37:39,048
and is already
several meters above the forest floor.
310
00:37:40,800 --> 00:37:43,844
Something has taken control
of its movements,
311
00:37:44,178 --> 00:37:47,431
like a puppeteer
pulling at the strings of a marionette.
312
00:37:54,063 --> 00:37:58,943
There's just one final act,
for which the ant has no choice.
313
00:38:03,656 --> 00:38:08,995
It must find a place to bite down,
tethering it to the vegetation.
314
00:38:24,343 --> 00:38:26,762
With the ant in its death grip,
315
00:38:27,179 --> 00:38:31,517
a parasitic fungus, Cordyceps,
erupts from its body.
316
00:38:41,485 --> 00:38:46,240
Finally, the fruiting body of the fungus
bursts from its head.
317
00:39:01,172 --> 00:39:05,843
From this bulbous container,
spores will be cast into the air currents,
318
00:39:05,926 --> 00:39:09,055
where they will claim more ant victims.
319
00:39:13,476 --> 00:39:15,061
But it's not just ants.
320
00:39:15,853 --> 00:39:19,315
Many others are infected
by the Cordyceps fungus.
321
00:39:38,459 --> 00:39:40,544
The more numerous a species is,
322
00:39:40,628 --> 00:39:44,965
the more likely it is to fall victim
to the killer fungus.
323
00:39:52,390 --> 00:39:57,269
Checks and balances like these
means no one species can ever dominate,
324
00:39:58,270 --> 00:40:01,482
so protecting
the jungle's incredible diversity.
325
00:40:15,121 --> 00:40:19,417
But today,
the diversity of the world's rain forests
326
00:40:19,625 --> 00:40:22,253
is falling at an alarming rate,
327
00:40:23,129 --> 00:40:25,005
and that is because of us.
328
00:40:29,093 --> 00:40:34,974
We have now replaced
up to 27 million hectares of virgin jungle
329
00:40:35,349 --> 00:40:37,810
with a single species of tree.
330
00:40:42,398 --> 00:40:44,233
This is oil palm,
331
00:40:44,900 --> 00:40:47,194
one of the world's most productive crops.
332
00:40:48,571 --> 00:40:49,864
But these monocultures
333
00:40:49,947 --> 00:40:55,494
support only a fraction of the diversity
found in primary rain forests,
334
00:40:56,370 --> 00:40:59,540
and it is pushing many animals
to extinction.
335
00:41:04,003 --> 00:41:07,506
In the swamp forests of northern Sumatra,
in Indonesia,
336
00:41:07,882 --> 00:41:11,760
time is running out
for one of our closest ancestors.
337
00:41:14,305 --> 00:41:15,598
The orangutan.
338
00:41:21,061 --> 00:41:25,858
A baby orangutan takes more than ten years
to become independent.
339
00:41:28,319 --> 00:41:30,654
Everything must be learned
from its mother.
340
00:41:31,739 --> 00:41:34,992
Like how to bridge the gaps between trees.
341
00:41:40,831 --> 00:41:43,292
Survival depends on each orang
342
00:41:43,375 --> 00:41:46,462
understanding its patch of forest
perfectly.
343
00:41:49,381 --> 00:41:53,636
Watching scientists
have named this pair Ellie and Eden.
344
00:41:56,347 --> 00:41:57,973
Ellie is 18 years old,
345
00:41:59,975 --> 00:42:02,770
and Eden, her first baby, is three.
346
00:42:07,608 --> 00:42:11,403
Right now,
he needs a little bit of encouragement.
347
00:42:20,829 --> 00:42:22,373
Like all orangutans,
348
00:42:22,831 --> 00:42:25,584
Ellie has a mental map
of her surroundings,
349
00:42:26,377 --> 00:42:29,838
including the location
of every fruiting tree.
350
00:42:34,969 --> 00:42:37,137
Eden needs to learn this, too,
351
00:42:37,721 --> 00:42:41,517
but for now,
he must watch everything his mother does,
352
00:42:42,977 --> 00:42:47,690
learning not just what's edible
but also how to eat it.
353
00:42:58,659 --> 00:43:02,037
Every day is a new lesson for Eden.
354
00:43:06,125 --> 00:43:11,130
Here, ants are a big part of their diet,
and there's a knack to gathering them.
355
00:43:15,718 --> 00:43:19,471
Once tangled in Ellie's fur,
they're easy to pick off.
356
00:43:23,976 --> 00:43:28,314
For little Eden,
it's all about watching and learning.
357
00:43:35,029 --> 00:43:38,741
Eden's cousin, Louis, is more experienced.
358
00:43:40,200 --> 00:43:41,577
Four years older than Eden,
359
00:43:42,119 --> 00:43:44,455
he can move through the branches
with ease.
360
00:43:55,215 --> 00:43:57,885
It's taken a few years to master,
361
00:43:58,802 --> 00:44:02,473
and it's clearly a skill
he feels is worth showing off.
362
00:44:13,275 --> 00:44:18,697
Conquering the treetops is just stage one
in an orangutan's education.
363
00:44:19,198 --> 00:44:22,159
To survive, Louis must learn more.
364
00:44:24,870 --> 00:44:26,038
Much more.
365
00:44:29,416 --> 00:44:32,336
His mother, Lisa,
has found a rotten tree trunk
366
00:44:32,920 --> 00:44:34,630
with lots of ants.
367
00:44:35,839 --> 00:44:40,052
But this anting opportunity
requires more know-how.
368
00:44:41,512 --> 00:44:44,973
To get them, Lisa must break sections off.
369
00:44:50,979 --> 00:44:53,899
At his age, Louis must do more than watch.
370
00:44:56,860 --> 00:44:57,945
He must copy.
371
00:45:16,004 --> 00:45:17,005
Not a bad effort.
372
00:45:21,885 --> 00:45:26,974
But even at the age of seven,
he's yet to master the art of ant capture.
373
00:45:33,105 --> 00:45:35,107
Louis has much to learn.
374
00:45:39,653 --> 00:45:44,074
Pluto, on the other hand,
graduated a long time ago.
375
00:45:46,118 --> 00:45:48,829
Thirty years old
and nearly a hundred kilograms,
376
00:45:49,163 --> 00:45:51,123
he is king of this jungle.
377
00:45:54,042 --> 00:45:57,129
His cheek flanges are a sign of power,
378
00:45:58,172 --> 00:46:00,257
something for Louis to aspire to.
379
00:46:06,013 --> 00:46:08,974
Pluto is constantly
on the lookout for food,
380
00:46:10,726 --> 00:46:13,729
and he's just spotted
a promising opportunity.
381
00:46:16,774 --> 00:46:19,860
These wasps mean one thing to him.
382
00:46:21,653 --> 00:46:23,155
Tasty grubs.
383
00:46:28,410 --> 00:46:33,123
To get at them,
he favors a smash-and-grab technique.
384
00:46:39,254 --> 00:46:43,300
His thick fur protects him
from most of the angry wasps,
385
00:46:43,801 --> 00:46:46,762
but the rewards
are worth risking a few stings.
386
00:46:52,434 --> 00:46:54,353
Louis keeps his distance.
387
00:46:57,981 --> 00:47:00,609
He would need to be
a lot bigger and hairier
388
00:47:00,776 --> 00:47:02,820
before he could do battle with wasps.
389
00:47:10,327 --> 00:47:15,123
But here, there's one trick that can take
half a lifetime to get to grips with.
390
00:47:22,464 --> 00:47:27,094
Louis' mother, Lisa, has learned
how to make tools from sticks,
391
00:47:27,469 --> 00:47:29,388
to winkle out insects.
392
00:47:31,598 --> 00:47:33,141
The orangutans living here
393
00:47:33,308 --> 00:47:36,728
are the only ones in the world
to have discovered this skill.
394
00:47:40,357 --> 00:47:42,359
Louis must try and learn it too,
395
00:47:42,442 --> 00:47:46,113
but it may be another eight years
before he's as good as his mother.
396
00:47:49,366 --> 00:47:52,369
This long education has made orangutans
397
00:47:52,452 --> 00:47:56,206
particularly vulnerable
to changes taking place in their forest.
398
00:48:01,420 --> 00:48:06,341
It's now estimated that we lose
100 orangutans every week
399
00:48:06,800 --> 00:48:08,468
from human activity.
400
00:48:17,728 --> 00:48:23,400
Louis and Eden's generation
could be the last wild orangutan.
401
00:48:28,530 --> 00:48:33,744
When Pluto was their age,
his jungle home stretched to the horizon.
402
00:48:39,625 --> 00:48:41,084
Not anymore.
403
00:48:44,338 --> 00:48:46,256
In the last four decades,
404
00:48:46,673 --> 00:48:50,636
the pristine lowland jungle
that orangutans depend on
405
00:48:51,219 --> 00:48:55,474
has declined by a staggering 75 percent.
406
00:48:58,727 --> 00:49:02,189
Across the world,
we are losing tropical forest
407
00:49:02,439 --> 00:49:07,110
at the rate
of nearly 15 million hectares every year,
408
00:49:08,362 --> 00:49:12,574
and with it,
the planet's treasure trove of diversity.
409
00:49:15,535 --> 00:49:21,917
Jungles store and capture more carbon
than any other habitat on land.
410
00:49:23,168 --> 00:49:24,920
They cool our planet,
411
00:49:25,837 --> 00:49:27,798
provide food and medicines.
412
00:49:29,633 --> 00:49:32,052
We lose them at our peril.
