1
00:00:20,440 --> 00:00:22,080
200 million years ago,
2
00:00:22,080 --> 00:00:23,960
our planet looked very different
3
00:00:23,960 --> 00:00:25,520
from what it does today.
4
00:00:25,520 --> 00:00:27,960
It was entirely covered by sea,
5
00:00:27,960 --> 00:00:32,640
which surrounded one single
supercontinent we call Pangea.
6
00:00:34,840 --> 00:00:37,480
And then Pangea began to break up.
7
00:00:39,640 --> 00:00:42,160
Life was cast adrift
8
00:00:42,160 --> 00:00:43,880
on fragments of land.
9
00:00:46,280 --> 00:00:50,600
And these fragments eventually
became our seven continents.
10
00:00:53,280 --> 00:00:56,760
We will see how life developed
on each continent,
11
00:00:56,760 --> 00:01:00,880
giving rise to the extraordinary
and wonderful diversity
12
00:01:00,880 --> 00:01:02,200
that we see today.
13
00:01:03,760 --> 00:01:09,120
We'll venture through the frozen
wilderness of Antarctica,
14
00:01:09,120 --> 00:01:11,920
where life thrives against the odds.
15
00:01:14,560 --> 00:01:18,000
And to the riches of South America,
16
00:01:18,000 --> 00:01:19,520
full of the unexpected.
17
00:01:23,920 --> 00:01:25,920
From the wilds of Africa.
18
00:01:28,840 --> 00:01:33,000
To the vast expanses of North
America
19
00:01:33,000 --> 00:01:35,360
and the searing heat of Australia.
20
00:01:38,200 --> 00:01:43,160
We'll explore
the remote reaches of Asia,
21
00:01:43,160 --> 00:01:45,120
home to rarely seen creatures.
22
00:01:47,720 --> 00:01:51,960
And Europe, a world transformed
by humanity.
23
00:01:57,600 --> 00:01:59,960
And we'll discover how this may be
24
00:01:59,960 --> 00:02:03,480
the most critical moment
for life on Earth
25
00:02:03,480 --> 00:02:05,000
since the continents formed.
26
00:02:06,640 --> 00:02:09,440
We are changing the world
so rapidly,
27
00:02:09,440 --> 00:02:14,040
that wildlife is now facing some of
its greatest challenges yet.
28
00:02:17,880 --> 00:02:20,920
Never has it been
a more important time
29
00:02:20,920 --> 00:02:24,120
to reveal the precious diversity
of life
30
00:02:24,120 --> 00:02:26,080
on our seven continents.
31
00:02:49,840 --> 00:02:53,160
This is Seven Worlds, One Planet.
32
00:03:20,120 --> 00:03:23,280
Of all the continents,
33
00:03:23,280 --> 00:03:27,520
one was first sighted by humans
just 200 years ago.
34
00:03:31,640 --> 00:03:32,960
And only now
35
00:03:32,960 --> 00:03:35,200
are we beginning to understand
36
00:03:35,200 --> 00:03:37,360
what it takes to survive here.
37
00:03:43,560 --> 00:03:46,160
It's the most hostile of them all.
38
00:04:00,720 --> 00:04:04,280
98% of mainland Antarctica,
39
00:04:04,280 --> 00:04:08,240
an area one-and-a-half times the
size of the United States,
40
00:04:08,240 --> 00:04:11,560
is covered in ice
41
00:04:11,560 --> 00:04:14,520
on which virtually
nothing can live.
42
00:04:21,760 --> 00:04:25,640
So life is dependent on the ocean
that surrounds it.
43
00:04:28,240 --> 00:04:30,240
But even the ocean freezes.
44
00:04:33,560 --> 00:04:37,320
Only one mammal can live
this far south.
45
00:04:40,840 --> 00:04:42,600
The Weddell seal.
46
00:04:45,320 --> 00:04:48,160
She has to keep her breathing hole
open
47
00:04:48,160 --> 00:04:51,360
by grinding back the ice
with her teeth.
48
00:05:04,600 --> 00:05:06,560
Out here on the sea ice,
49
00:05:06,560 --> 00:05:10,960
all these seals are far from the
predators of the open ocean.
50
00:05:12,440 --> 00:05:16,680
So, this is the safest place
for her to give birth.
51
00:05:19,040 --> 00:05:22,280
Leaving the warmth of the womb
and landing on ice
52
00:05:22,280 --> 00:05:26,760
is the sharpest drop in temperature
any animal ever faces.
53
00:05:36,280 --> 00:05:41,000
But her pup can't swim for the first
ten days of its life.
54
00:05:46,160 --> 00:05:48,040
It's trapped here
55
00:05:48,040 --> 00:05:49,360
out on the ice.
56
00:06:10,360 --> 00:06:12,360
She shields her pup from the wind.
57
00:06:14,920 --> 00:06:18,680
Although in spring,
temperatures can drop
58
00:06:18,680 --> 00:06:21,200
to minus 40 degrees Celsius,
59
00:06:21,200 --> 00:06:23,520
and blizzards can rage for days.
60
00:06:47,080 --> 00:06:50,560
Three days on, and the storm
is still raging.
61
00:06:52,640 --> 00:06:55,560
She now faces the hardest
of decisions.
62
00:07:01,920 --> 00:07:03,480
Does she stay with her pup?
63
00:07:10,080 --> 00:07:11,840
Or shelter in the water?
64
00:07:34,840 --> 00:07:38,440
Now, her pup's best chance
of survival
65
00:07:38,440 --> 00:07:41,120
is for the storm to pass quickly.
66
00:08:04,520 --> 00:08:06,720
Some pups didn't make it.
67
00:08:19,200 --> 00:08:20,240
An answer.
68
00:08:36,120 --> 00:08:40,320
If this pup now joins its mother
in the water,
69
00:08:40,320 --> 00:08:42,000
it will be safe
70
00:08:42,000 --> 00:08:43,600
from any future storm.
71
00:08:52,160 --> 00:08:55,280
It's minus two degrees Celsius,
72
00:08:55,280 --> 00:08:57,760
but being in water is warmer
73
00:08:57,760 --> 00:08:59,440
than lying on the ice
74
00:08:59,440 --> 00:09:00,880
in the howling wind.
75
00:09:05,680 --> 00:09:10,200
Its chances of surviving
here are now extremely good.
76
00:09:22,000 --> 00:09:27,200
Only a few hardy animals can live
all year round as far south as this.
77
00:09:30,280 --> 00:09:31,760
Further from the pole,
78
00:09:31,760 --> 00:09:33,480
on the fringes of the continent,
79
00:09:33,480 --> 00:09:36,320
lie islands
that are free of sea ice.
80
00:09:42,200 --> 00:09:45,040
Here, there are other challenges.
81
00:09:50,480 --> 00:09:53,040
St Andrews Bay on South
Georgia
82
00:09:53,040 --> 00:09:56,320
is packed with half
a million king penguins.
83
00:10:04,760 --> 00:10:07,920
In spring, the chicks are left
for days,
84
00:10:07,920 --> 00:10:10,240
while their parents are away
85
00:10:10,240 --> 00:10:12,040
collecting food for them.
86
00:10:14,160 --> 00:10:17,240
There is a simple arrangement.
87
00:10:17,240 --> 00:10:20,360
The chicks must stay exactly
where their parents left them
88
00:10:20,360 --> 00:10:22,680
to be sure of being found again.
89
00:10:34,040 --> 00:10:37,480
But this chick has
decided to look around.
90
00:10:46,640 --> 00:10:49,120
There is a lot to be investigated.
91
00:11:33,280 --> 00:11:35,320
But it must not stray too far
92
00:11:35,320 --> 00:11:37,120
from its meeting place.
93
00:11:41,480 --> 00:11:42,960
This parent has returned
94
00:11:42,960 --> 00:11:44,280
with food in its crop.
95
00:11:45,720 --> 00:11:48,480
But its chick isn't where
it left it.
96
00:11:52,280 --> 00:11:53,520
It's hard to stay put
97
00:11:53,520 --> 00:11:55,640
when there's so much to play with.
98
00:11:59,920 --> 00:12:01,880
Elephant seals are here, too.
99
00:12:05,680 --> 00:12:07,040
Very mysterious.
100
00:12:33,000 --> 00:12:35,400
Finding it
in the crowd of youngsters
101
00:12:35,400 --> 00:12:37,080
is not going to be easy.
102
00:12:38,440 --> 00:12:40,960
They must recognise each other
by their calls.
103
00:12:47,160 --> 00:12:49,960
But to hear these in such
a noisy colony,
104
00:12:49,960 --> 00:12:52,480
then they must be within
15 metres of each other.
105
00:13:23,120 --> 00:13:24,560
Reunited.
106
00:13:35,680 --> 00:13:40,240
St Andrews Beach is one
of the most crowded on the planet,
107
00:13:40,240 --> 00:13:43,440
and so holding a territory
here is a constant battle.
108
00:13:48,320 --> 00:13:50,760
This bull elephant seal holds
109
00:13:50,760 --> 00:13:54,160
the mating rights to 60 females.
110
00:13:58,320 --> 00:14:02,200
For two months, he's guarded
this stretch of beach.
111
00:14:03,720 --> 00:14:04,960
Unable to feed,
112
00:14:04,960 --> 00:14:08,120
he's losing ten kilos a day,
113
00:14:08,120 --> 00:14:10,280
and he's exhausted.
114
00:14:14,200 --> 00:14:16,520
But other bulls are lying around,
115
00:14:16,520 --> 00:14:18,160
waiting their chance.
116
00:15:27,480 --> 00:15:30,080
Blubber, 15 centimetres thick,
117
00:15:30,080 --> 00:15:32,720
is protection against the cold,
118
00:15:32,720 --> 00:15:34,320
but not from the impact
119
00:15:34,320 --> 00:15:36,200
of a four-tonne opponent.
120
00:16:05,360 --> 00:16:06,880
He holds his ground
121
00:16:06,880 --> 00:16:08,760
and forces the intruder
122
00:16:08,760 --> 00:16:10,000
back out to sea.
123
00:16:19,160 --> 00:16:21,920
Life in the Antarctic is harsh
indeed.
124
00:16:23,160 --> 00:16:25,320
But all these creatures come here
125
00:16:25,320 --> 00:16:27,080
because the Southern Ocean
126
00:16:27,080 --> 00:16:28,960
is one of the richest on Earth.
127
00:16:32,600 --> 00:16:34,480
When, 30 million years ago,
128
00:16:34,480 --> 00:16:36,240
the continent broke away
129
00:16:36,240 --> 00:16:39,040
from South America and drifted
south,
130
00:16:39,040 --> 00:16:41,840
currents began to swirl
right around it.
131
00:16:48,280 --> 00:16:49,880
They are now the strongest
132
00:16:49,880 --> 00:16:51,720
of any currents on the planet.
133
00:16:58,160 --> 00:17:00,800
They sweep up nutrients
from the depths,
134
00:17:00,800 --> 00:17:04,160
and so create one of
the richest feeding grounds
135
00:17:04,160 --> 00:17:06,080
in all the world's oceans.
136
00:17:10,520 --> 00:17:11,960
And some of the creatures
137
00:17:11,960 --> 00:17:13,280
that come here to feast
138
00:17:13,280 --> 00:17:16,000
do so in a most sophisticated way.
139
00:17:35,560 --> 00:17:37,240
Humpback whales.
140
00:17:41,520 --> 00:17:43,760
It's summer, and they've come here
141
00:17:43,760 --> 00:17:45,000
for a banquet.
142
00:18:01,360 --> 00:18:03,240
The cold waters contain
143
00:18:03,240 --> 00:18:05,440
great shoals of krill.
144
00:18:07,840 --> 00:18:12,000
It's estimated that there are 400
trillion of them
145
00:18:12,000 --> 00:18:15,480
and that their combined weight is
greater than that of any other
146
00:18:15,480 --> 00:18:17,640
animal species on the planet.
147
00:18:22,000 --> 00:18:25,840
To collect them, the humpbacks blow
curtains of bubbles,
148
00:18:25,840 --> 00:18:28,480
which the krill won't cross.
149
00:18:35,720 --> 00:18:41,120
The whales then rise, spiralling
inwards, to concentrate the swarm.
150
00:18:54,320 --> 00:18:58,320
Summer in Antarctica is a time of
plenty,
151
00:18:58,320 --> 00:19:02,000
when most humpbacks are able to put
on the reserves they need
152
00:19:02,000 --> 00:19:04,200
for the whole year.
153
00:19:07,200 --> 00:19:11,520
But the wildlife in these waters
faces an uncertain future.
154
00:19:16,520 --> 00:19:19,200
The Southern Ocean is warming.
155
00:19:25,320 --> 00:19:29,760
90% of the world's ice lies in
Antarctica
156
00:19:29,760 --> 00:19:32,680
and, in some parts, the rate at
which it's melting
157
00:19:32,680 --> 00:19:35,160
is doubling every decade.
158
00:19:37,920 --> 00:19:40,320
Sea levels are rising.
159
00:19:42,000 --> 00:19:44,920
But there is a more immediate
threat.
160
00:19:47,480 --> 00:19:52,000
The warming of the coldest region on
Earth is having a profound effect
161
00:19:52,000 --> 00:19:54,200
on global weather patterns.
162
00:19:55,720 --> 00:20:00,760
And this change in the climate is
already being felt right here.
163
00:20:05,440 --> 00:20:09,560
This grey-headed albatross chick is
four weeks old.
164
00:20:12,200 --> 00:20:16,520
So far, it has been sheltered from
the gales by its parents,
165
00:20:16,520 --> 00:20:19,920
who take turns to collect food for
it out at sea.
166
00:20:26,000 --> 00:20:30,480
It is the only chick that they
will have in two years.
167
00:20:38,320 --> 00:20:42,400
The delicate touching of beaks
strengthens their bond.
168
00:21:02,120 --> 00:21:05,920
But these tender moments cannot last
forever.
169
00:21:11,200 --> 00:21:15,120
As a chick grows, so does its
appetite.
170
00:21:15,120 --> 00:21:19,560
So one parent has to leave to find
food before the other returns.
171
00:21:23,680 --> 00:21:28,520
Parting is a big step
and they take time over it.
172
00:22:05,000 --> 00:22:09,320
For the first time in its life,
this chick is alone.
173
00:22:18,800 --> 00:22:23,080
The Antarctic is the windiest
continent,
174
00:22:23,080 --> 00:22:27,000
and in recent years, climate change
has brought storms
175
00:22:27,000 --> 00:22:30,120
that are more frequent and even more
powerful.
176
00:22:39,760 --> 00:22:43,480
Winds now regularly reach 70mph.
177
00:22:50,680 --> 00:22:54,720
But the albatross chicks must try to
stay on their nests.
178
00:23:48,520 --> 00:23:51,280
Surviving the storm is one thing...
179
00:23:53,120 --> 00:23:57,120
..but now, off the nest in these
freezing temperatures,
180
00:23:57,120 --> 00:24:00,080
this chick has just hours to live.
181
00:24:11,920 --> 00:24:15,400
The brutal conditions have taken
their toll.
182
00:24:19,280 --> 00:24:22,720
Some chicks have already succumbed
to exposure.
183
00:24:34,080 --> 00:24:39,240
The bond is so strong, it can be
hard for a father to let go.
184
00:24:44,200 --> 00:24:47,400
The albatross population here has
more than halved
185
00:24:47,400 --> 00:24:50,000
in the last 15 years.
186
00:24:53,480 --> 00:24:57,040
These albatross are facing
extinction.
187
00:24:58,960 --> 00:25:02,280
They simply cannot keep pace with
the changes
188
00:25:02,280 --> 00:25:04,920
affecting their world.
189
00:25:26,000 --> 00:25:29,560
More parents are returning to the
colony.
190
00:25:40,000 --> 00:25:42,720
Something is not right.
191
00:25:45,720 --> 00:25:48,600
The nest should not be empty.
192
00:25:58,800 --> 00:26:02,840
The chick is actually right below
its parent,
193
00:26:02,840 --> 00:26:07,320
but because it's not on the nest,
the parent doesn't recognise it.
194
00:26:16,960 --> 00:26:19,320
And doesn't help it.
195
00:26:23,920 --> 00:26:28,960
Strangely, perhaps, these albatross
do not recognise their chicks
196
00:26:28,960 --> 00:26:31,720
by sight, sound or smell.
197
00:26:33,240 --> 00:26:37,040
They identify them by finding them
on the nest.
198
00:26:40,560 --> 00:26:44,320
So, these violent storms have
created a problem
199
00:26:44,320 --> 00:26:47,960
that the albatross are not equipped
to solve.
200
00:26:56,280 --> 00:27:00,960
If it is to survive, the chick will
have to get back on the nest
201
00:27:00,960 --> 00:27:03,520
by itself.
202
00:28:01,040 --> 00:28:03,360
The chick has made it.
203
00:28:05,600 --> 00:28:09,000
The bond is re-established
immediately
204
00:28:09,000 --> 00:28:13,280
and its parent, once again, provides
the warmth that the chick
205
00:28:13,280 --> 00:28:15,560
so desperately needs.
206
00:28:23,640 --> 00:28:26,640
It's safe...for now.
207
00:28:47,760 --> 00:28:51,800
Nowhere in Antarctica is
survival easy.
208
00:28:54,000 --> 00:28:57,920
Gentoo penguins travel up to 50
miles every day
209
00:28:57,920 --> 00:29:00,200
to find food.
210
00:29:00,200 --> 00:29:03,000
And they're now returning to their
chicks.
211
00:29:04,880 --> 00:29:07,640
They are the fastest penguin
in the sea
212
00:29:07,640 --> 00:29:10,480
and can swim at 22mph.
213
00:29:13,360 --> 00:29:16,680
But other animals can swim much
faster.
214
00:29:26,000 --> 00:29:28,400
Orca.
215
00:29:41,040 --> 00:29:44,640
This penguin must
rely on its agility.
216
00:31:06,000 --> 00:31:10,960
With four orcas chasing it, the
penguin stood little chance.
217
00:31:38,880 --> 00:31:43,040
Most gentoo parents do make it back
to the colony.
218
00:31:46,760 --> 00:31:50,280
Today, it's been a good hunt for
krill.
219
00:31:53,360 --> 00:31:55,920
Perhaps too good.
220
00:31:58,520 --> 00:32:02,480
The chicks grow and it seems that
the Mohawk style
221
00:32:02,480 --> 00:32:04,520
is back in fashion.
222
00:32:06,840 --> 00:32:09,040
It's just a phase.
223
00:32:09,040 --> 00:32:11,080
He'll grow out of it.
224
00:32:13,840 --> 00:32:18,040
He'll soon lose these remaining down
feathers and be ready to leave
225
00:32:18,040 --> 00:32:21,000
the colony and collect food for
himself.
226
00:32:22,080 --> 00:32:27,360
But doing so is becoming harder
because of climate change.
227
00:32:33,920 --> 00:32:37,120
Glaciers in the region are now
calving faster
228
00:32:37,120 --> 00:32:40,560
than they have done since records
began.
229
00:32:47,360 --> 00:32:51,000
And this brash ice now fills the
bays.
230
00:33:01,720 --> 00:33:03,800
It's autumn.
231
00:33:05,960 --> 00:33:10,400
The chicks have lost their down
feathers and they're hungry.
232
00:33:11,680 --> 00:33:15,200
They must go to
sea for the first time.
233
00:33:18,560 --> 00:33:22,800
But now there's a risk of being
crushed between blocks of ice.
234
00:33:28,720 --> 00:33:31,880
They have to get to the distant
icebergs...
235
00:33:34,560 --> 00:33:38,160
..and so reach the open ocean that
lies beyond.
236
00:33:41,840 --> 00:33:44,760
And that is easier said than done.
237
00:33:54,240 --> 00:33:56,480
A leopard seal...
238
00:33:57,840 --> 00:34:00,080
..their main predator.
239
00:34:01,360 --> 00:34:04,320
It's a giant, three metres long.
240
00:34:06,600 --> 00:34:10,640
These icy conditions help
it to hunt.
241
00:34:18,920 --> 00:34:22,280
The penguins can neither
walk nor swim.
242
00:34:32,240 --> 00:34:36,240
They have no way of telling
where the seal will strike.
243
00:35:13,440 --> 00:35:16,320
These are easy pickings.
244
00:35:28,160 --> 00:35:31,000
For some, it's time to retreat.
245
00:36:07,000 --> 00:36:10,000
But now, it's back to square one.
246
00:36:14,280 --> 00:36:19,440
There's no alternative
but to run the gauntlet once again.
247
00:36:52,880 --> 00:36:56,800
The seal seems to be toying with
this penguin.
248
00:36:59,880 --> 00:37:02,680
But safety is in sight.
249
00:37:19,440 --> 00:37:22,320
The ice floe is near the open ocean.
250
00:37:26,000 --> 00:37:28,840
But this penguin is exhausted.
251
00:38:08,640 --> 00:38:11,600
Perhaps it's not worth it, after
all.
252
00:38:37,000 --> 00:38:39,400
Winter is coming.
253
00:38:43,280 --> 00:38:47,560
Antarctica now undergoes a major
transformation.
254
00:38:50,240 --> 00:38:55,080
Every day, 40,000 more square miles
of sea freeze over.
255
00:38:57,840 --> 00:39:02,040
By the end of winter, the continent
has doubled in size.
256
00:39:04,680 --> 00:39:08,800
This is by far the largest
desert in the world.
257
00:39:26,520 --> 00:39:31,000
But the frozen surface of the sea
hides a great secret.
258
00:39:39,600 --> 00:39:43,480
It may be hostile above the ice,
but below it,
259
00:39:43,480 --> 00:39:47,240
conditions are so stable that life
over millennia
260
00:39:47,240 --> 00:39:49,840
has had time to diversify.
261
00:39:54,720 --> 00:39:58,160
Creatures here grow to a great size.
262
00:39:58,160 --> 00:40:01,600
Predatory nemertean worms are three
metres long.
263
00:40:05,600 --> 00:40:09,440
These dramas only become visible
when speeded up.
264
00:40:14,200 --> 00:40:18,000
We're only just beginning to
discover the details of the lives
265
00:40:18,000 --> 00:40:20,600
of such strange creatures.
266
00:40:25,600 --> 00:40:28,400
Nudibranchs are hermaphrodites.
267
00:40:31,240 --> 00:40:36,640
Each individual possesses both male
and female reproductive organs.
268
00:40:36,640 --> 00:40:39,760
So, to mate, one nudibranch
just needs to find
269
00:40:39,760 --> 00:40:42,000
another nudibranch.
270
00:40:42,000 --> 00:40:44,360
And any one will do.
271
00:40:46,480 --> 00:40:51,080
But nonetheless, this is a challenge
when their tiny eyes can barely see.
272
00:41:04,400 --> 00:41:07,080
Some do get lucky.
273
00:41:15,280 --> 00:41:19,760
They're fertilising each other and
both will produce young.
274
00:41:27,000 --> 00:41:30,840
When it's hard to find a partner,
it pays not to have to worry
275
00:41:30,840 --> 00:41:33,120
about your gender.
276
00:41:43,000 --> 00:41:48,000
Sea anemones may look like plants,
but, actually, are animals
277
00:41:48,000 --> 00:41:51,840
and feed by catching edible
particles that drift within reach
278
00:41:51,840 --> 00:41:54,000
of their tentacles.
279
00:41:57,000 --> 00:42:02,040
But being rooted to the sea floor
makes them vulnerable to predators.
280
00:42:05,320 --> 00:42:10,480
An ocean-going jellyfish, a metre
or so across, searching for food.
281
00:42:24,680 --> 00:42:27,240
The jellyfish senses prey.
282
00:42:49,000 --> 00:42:52,800
But it's the sea anemones that have
made the catch
283
00:42:52,800 --> 00:42:55,520
and they've grabbed a monster.
284
00:43:07,040 --> 00:43:10,600
A rare feast for these stationary
predators.
285
00:43:16,120 --> 00:43:20,200
They devour their catch over the
next four days.
286
00:43:32,880 --> 00:43:37,760
Life here under the ice has remained
unchanged for millennia.
287
00:43:39,120 --> 00:43:43,760
But in the last 200 years,
much of Antarctica's wildlife
288
00:43:43,760 --> 00:43:46,720
has had to face new predators...
289
00:43:50,440 --> 00:43:52,400
..human beings.
290
00:43:55,200 --> 00:43:59,600
We devised new hunting techniques
and used them so mercilessly
291
00:43:59,600 --> 00:44:03,000
that we almost exterminated the
great whales.
292
00:44:06,160 --> 00:44:10,000
These whaling stations on
South Georgia were at the centre
293
00:44:10,000 --> 00:44:12,280
of this industry.
294
00:44:22,520 --> 00:44:26,120
More than one-and-a-half million
whales were slaughtered
295
00:44:26,120 --> 00:44:28,880
in Antarctic waters.
296
00:44:31,840 --> 00:44:35,200
The blubber was stripped from
their massive bodies
297
00:44:35,200 --> 00:44:40,000
and boiled down in vats to make
margarine and soap.
298
00:44:43,000 --> 00:44:46,960
And the largest animal ever
recorded,
299
00:44:46,960 --> 00:44:52,720
a 33-metre blue whale, perhaps over
100 years old,
300
00:44:52,720 --> 00:44:56,760
was butchered on this ramp in just
two hours.
301
00:45:05,560 --> 00:45:10,200
This reckless slaughter marked a new
low in our relationship
302
00:45:10,200 --> 00:45:12,960
with the natural world.
303
00:45:41,880 --> 00:45:45,200
Southern right whales were hit the
hardest.
304
00:45:48,960 --> 00:45:52,000
They were so trusting and
inquisitive
305
00:45:52,000 --> 00:45:55,320
that they swam right up to the
whalers' boats.
306
00:45:57,640 --> 00:46:01,280
And the whalers called them right
whales
307
00:46:01,280 --> 00:46:04,600
because they were the right
whales to hunt.
308
00:46:13,640 --> 00:46:17,400
Mothers with calves were targeted
first.
309
00:46:20,320 --> 00:46:24,880
To give birth, females came to the
same sheltered bays
310
00:46:24,880 --> 00:46:28,640
and would not leave their calves
alone at the surface.
311
00:46:30,160 --> 00:46:35,200
In just decades,
a population of 35,000
312
00:46:35,200 --> 00:46:40,080
was so reduced that only 35 of the
females survived.
313
00:46:44,560 --> 00:46:47,200
But times have changed.
314
00:46:47,200 --> 00:46:52,880
A ban on the commercial hunting of
whales, introduced in 1986,
315
00:46:52,880 --> 00:46:57,320
has stopped all but Japan, Norway
and Iceland.
316
00:47:01,840 --> 00:47:05,200
Our relationship to these
remarkable creatures
317
00:47:05,200 --> 00:47:07,800
has undergone a huge shift.
318
00:47:10,480 --> 00:47:14,440
Scientists are now learning a great
deal about these whales.
319
00:47:18,640 --> 00:47:21,840
But we still don't know how long
they live.
320
00:47:25,240 --> 00:47:28,720
It's thought that some individuals
alive today
321
00:47:28,720 --> 00:47:32,080
were around at the time of the mass
slaughter.
322
00:47:33,360 --> 00:47:36,800
Yet these 60-tonne whales remain
gentle
323
00:47:36,800 --> 00:47:39,640
and inquisitive around humans.
324
00:47:47,600 --> 00:47:50,640
By putting a stop to commercial
hunting,
325
00:47:50,640 --> 00:47:55,040
this population of whales has now
grown to over 2,000.
326
00:48:18,000 --> 00:48:23,320
The recovery of life in Antarctic
waters may have a significance
327
00:48:23,320 --> 00:48:27,000
that extends far beyond the reaches
of the continent
328
00:48:27,000 --> 00:48:29,440
and will affect us all.
329
00:48:33,320 --> 00:48:36,800
Just off the coast of Elephant
Island,
330
00:48:36,800 --> 00:48:40,040
we have recently witnessed what
might be
331
00:48:40,040 --> 00:48:43,040
the greatest feeding spectacle on
Earth.
332
00:48:47,400 --> 00:48:51,960
On the horizon, over 150 whales
have gathered
333
00:48:51,960 --> 00:48:54,760
to feast on krill.
334
00:49:03,360 --> 00:49:08,080
This is the largest congregation of
great whales ever filmed.
335
00:49:20,840 --> 00:49:25,120
These are mostly fin whales,
up to 26 metres long.
336
00:49:28,080 --> 00:49:31,360
Humpback whales are dwarfed in
comparison.
337
00:49:34,880 --> 00:49:38,760
Thousands of animals from all over
Antarctic waters
338
00:49:38,760 --> 00:49:41,360
are making their way here.
339
00:49:53,240 --> 00:49:57,800
These seas are, once again,
beginning to brim with life.
340
00:50:02,280 --> 00:50:06,480
And scientists have discovered that
the Southern Ocean,
341
00:50:06,480 --> 00:50:10,160
and the life within it, soaks up
more than twice as much
342
00:50:10,160 --> 00:50:14,480
carbon from the atmosphere as the
Amazon rainforest.
343
00:50:23,800 --> 00:50:28,400
By protecting Antarctica, we don't
just protect the life here...
344
00:50:29,560 --> 00:50:33,320
..we are helping to restore the
natural balance
345
00:50:33,320 --> 00:50:35,960
of the entire planet.
346
00:50:58,960 --> 00:51:02,960
St Andrews Bay provides one of the
most spectacular sights
347
00:51:02,960 --> 00:51:05,360
in the whole of the Antarctic.
348
00:51:05,360 --> 00:51:08,080
But to get there, the team will have
to cross
349
00:51:08,080 --> 00:51:12,640
the roughest seas in the world,
and nerves are starting to show.
350
00:51:12,640 --> 00:51:14,680
The wind is picking up already!
351
00:51:17,560 --> 00:51:21,640
It'll take ten days at sea to reach
this remote location.
352
00:51:23,240 --> 00:51:27,080
And it's not long before they start
to feel a bit green.
353
00:51:30,760 --> 00:51:32,920
There's some big waves coming now.
354
00:51:32,920 --> 00:51:38,520
With these conditions lasting days,
all who can take shifts at the helm.
355
00:51:40,200 --> 00:51:43,760
And you get given a talk, to say if
you fall in the water here,
356
00:51:43,760 --> 00:51:47,160
there's nothing anyone can do -
they can't save you.
357
00:51:47,160 --> 00:51:50,840
It's so cold, you'll die in under
a couple of minutes.
358
00:51:50,840 --> 00:51:52,560
Wow!
359
00:51:57,000 --> 00:52:01,000
Below deck,
Rolf hasn't yet found his sea legs.
360
00:52:02,960 --> 00:52:04,880
Oh!
361
00:52:04,880 --> 00:52:08,040
For me, this is like punishment or
prisoner-ship or whatever.
362
00:52:08,040 --> 00:52:12,000
I mean, I can't understand at all
how people do this voluntarily,
363
00:52:12,000 --> 00:52:15,840
people dream of being on a boat or
sailing or anything.
364
00:52:15,840 --> 00:52:17,320
Look at that.
365
00:52:17,320 --> 00:52:19,480
I mean, look how much the boat is
moving.
366
00:52:19,480 --> 00:52:22,440
I feel like in a washing machine.
367
00:52:22,440 --> 00:52:25,960
The island of South Georgia finally
appears.
368
00:52:30,000 --> 00:52:33,480
It's a relief to step onto solid
land.
369
00:52:37,520 --> 00:52:40,440
Yeah, the seasickness is already
forgotten, to be honest!
370
00:52:40,440 --> 00:52:42,240
But it's all forgotten.
371
00:52:43,280 --> 00:52:46,400
It's just out of this world.
372
00:52:46,400 --> 00:52:49,240
It's so wonderful that these places
still exist.
373
00:52:54,960 --> 00:52:58,720
They will spend the next three weeks
in St Andrews Bay.
374
00:53:00,520 --> 00:53:05,160
Rolf is here to film the king
penguins in this enormous colony.
375
00:53:06,680 --> 00:53:11,920
And Mark must capture the elephant
seals' intense mating season.
376
00:53:15,680 --> 00:53:19,400
On such a crowded beach,
fights can break out anywhere.
377
00:53:24,640 --> 00:53:27,960
Males are up to six metres long
and they are pumped
378
00:53:27,960 --> 00:53:30,040
full of testosterone.
379
00:53:32,040 --> 00:53:37,400
The bulls take little notice of the
crew and will stop at nothing.
380
00:53:37,400 --> 00:53:39,400
Oh, my God!
381
00:54:04,280 --> 00:54:06,880
That went from nothing to being
nearly steam-rollered
382
00:54:06,880 --> 00:54:09,400
by four huge males.
383
00:54:15,760 --> 00:54:20,840
Beyond the chaos of the beach, Rolf
has king penguins in front of him,
384
00:54:20,840 --> 00:54:23,800
and, thankfully, he's smiling again.
385
00:54:23,800 --> 00:54:26,320
I would really call them
the gentleman penguins
386
00:54:26,320 --> 00:54:29,400
because they are very polite,
they're charming,
387
00:54:29,400 --> 00:54:31,080
they have humour.
388
00:54:31,080 --> 00:54:34,400
There's so many funny, lovely
moments.
389
00:54:34,400 --> 00:54:38,040
I absolutely adore these penguins
for that!
390
00:54:38,040 --> 00:54:42,600
But as weeks go by, the reality of
living amongst penguins
391
00:54:42,600 --> 00:54:44,840
comes to the fore.
392
00:54:46,040 --> 00:54:50,720
Every morning, I think,
"Wow, it's stinky!"
393
00:54:50,720 --> 00:54:55,240
But then I realise, these smells
come out of my shoes
394
00:54:55,240 --> 00:54:57,440
and it's myself.
395
00:54:57,440 --> 00:54:58,920
Oh!
396
00:55:05,080 --> 00:55:09,880
Back on the beach, the team is using
a stabilised camera rig.
397
00:55:11,040 --> 00:55:13,520
They can now react faster to fights.
398
00:55:14,640 --> 00:55:17,040
So far in the shoot, we've seen a
lot of quick fights,
399
00:55:17,040 --> 00:55:19,240
but we haven't
seen some extended fights,
400
00:55:19,240 --> 00:55:22,880
where you see one bull paired
401
00:55:22,880 --> 00:55:25,000
equally against another bull.
402
00:55:26,480 --> 00:55:28,280
These sights are rare.
403
00:55:28,280 --> 00:55:30,520
The team will need to be at the
ready.
404
00:55:30,520 --> 00:55:32,720
Mark, Mark, Mark!
405
00:55:32,720 --> 00:55:34,920
Let's get running.
406
00:55:39,360 --> 00:55:41,440
Oh, hello!
407
00:55:58,720 --> 00:56:01,000
These are two huge, evenly matched
boys.
408
00:56:01,000 --> 00:56:02,240
I know.
409
00:56:02,240 --> 00:56:04,880
Wow, I never thought we'd be this
close to it. I know, nor did I.
410
00:56:04,880 --> 00:56:07,600
This is really tense, we've just got
to watch out.
411
00:56:12,960 --> 00:56:14,960
We got there.
412
00:56:18,120 --> 00:56:20,800
I never thought I'd see it that
close
413
00:56:20,800 --> 00:56:24,000
and be able to move around it, as
this kind of
414
00:56:24,000 --> 00:56:26,160
aggressive ballet is happening.
415
00:56:26,160 --> 00:56:27,600
Oh!
416
00:56:28,800 --> 00:56:30,960
And it does make you quite tense.
417
00:56:32,760 --> 00:56:37,240
The shoot is going well, but the
crew are noticing worrying signs.
418
00:56:39,480 --> 00:56:41,960
It's a really hot day today.
419
00:56:43,320 --> 00:56:46,960
30 years ago, the front of that
glacier
420
00:56:46,960 --> 00:56:49,680
was right down on the beach.
421
00:56:49,680 --> 00:56:52,600
It's retreated a huge amount.
422
00:56:52,600 --> 00:56:56,480
I don't really know what climate
change is going to mean
423
00:56:56,480 --> 00:56:59,800
for all the wildlife that's living
here.
424
00:56:59,800 --> 00:57:03,200
Parts of the Antarctic are warming
five times faster
425
00:57:03,200 --> 00:57:05,480
than the rest of the world.
426
00:57:06,800 --> 00:57:10,680
If this trend continues, it will
threaten the very existence
427
00:57:10,680 --> 00:57:12,960
of these polar creatures.
428
00:57:15,800 --> 00:57:19,640
On the last day of filming, the team
can't help but reflect
429
00:57:19,640 --> 00:57:22,760
on the future of the wildlife here.
430
00:57:22,760 --> 00:57:26,400
For me, it's emotional because I
know this might have been
431
00:57:26,400 --> 00:57:28,720
a once-in-a-lifetime experience.
432
00:57:29,840 --> 00:57:33,440
I will definitely take big memories
with me and I will be sad.
433
00:57:35,600 --> 00:57:38,480
It's a really special place,
you know? So...
434
00:57:40,200 --> 00:57:42,320
I don't know.
435
00:57:44,880 --> 00:57:48,560
I just hope we can keep these
places.
436
00:57:49,720 --> 00:57:51,840
And protect them.
437
00:58:07,880 --> 00:58:10,080
Next time...
438
00:58:10,080 --> 00:58:12,640
..the largest continent on Earth.
439
00:58:16,160 --> 00:58:18,880
A world of extremes...
440
00:58:18,880 --> 00:58:22,600
..where rarely seen animals roam the
land...
441
00:58:29,400 --> 00:58:31,640
..Asia.
