2
00:00:20,794 --> 00:00:22,434
200 million years ago,

3
00:00:22,574 --> 00:00:24,413
our planet looked very different

4
00:00:24,414 --> 00:00:26,013
from what it does today.

5
00:00:26,014 --> 00:00:28,493
It was entirely covered by sea,

6
00:00:28,494 --> 00:00:33,134
which surrounded one single
supercontinent we call Pangea.

7
00:00:35,189 --> 00:00:37,829
And then Pangea began to break up.

8
00:00:39,989 --> 00:00:42,468
Life was cast adrift

9
00:00:42,469 --> 00:00:44,149
on fragments of land.

10
00:00:46,589 --> 00:00:50,989
And these fragments eventually
became our seven continents.

11
00:00:53,709 --> 00:00:57,148
We will see how life developed
on each continent,

12
00:00:57,149 --> 00:01:01,188
giving rise to the extraordinary
and wonderful diversity

13
00:01:01,189 --> 00:01:02,469
that we see today.

14
00:01:04,109 --> 00:01:09,468
We'll venture through the frozen
wilderness of Antarctica,

15
00:01:09,469 --> 00:01:12,189
where life thrives against the odds.

16
00:01:14,789 --> 00:01:18,348
And to the riches of South America,

17
00:01:18,349 --> 00:01:19,869
full of the unexpected.

18
00:01:24,229 --> 00:01:26,229
From the wilds of Africa.

19
00:01:29,189 --> 00:01:33,308
To the vast expanses of North
America

20
00:01:33,309 --> 00:01:35,709
and the searing heat of Australia.

21
00:01:38,589 --> 00:01:43,428
We'll explore
the remote reaches of Asia,

22
00:01:43,429 --> 00:01:45,469
home to rarely seen creatures.

23
00:01:48,149 --> 00:01:52,269
And Europe, a world transformed
by humanity.

24
00:01:57,869 --> 00:02:00,308
And we'll discover how this may be

25
00:02:00,309 --> 00:02:03,788
the most critical moment
for life on Earth

26
00:02:03,789 --> 00:02:05,309
since the continents formed.

27
00:02:07,029 --> 00:02:09,868
We are changing the world
so rapidly,

28
00:02:09,869 --> 00:02:14,309
that wildlife is now facing some of
its greatest challenges yet.

29
00:02:18,229 --> 00:02:21,228
Never has it been
a more important time

30
00:02:21,229 --> 00:02:24,468
to reveal the precious diversity
of life

31
00:02:24,469 --> 00:02:26,309
on our seven continents.

32
00:02:50,109 --> 00:02:53,509
This is Seven Worlds, One Planet.

33
00:03:20,429 --> 00:03:23,628
Of all the continents,

34
00:03:23,629 --> 00:03:27,829
one was first sighted by humans
just 200 years ago.

35
00:03:31,949 --> 00:03:33,268
And only now

36
00:03:33,269 --> 00:03:35,548
are we beginning to understand

37
00:03:35,549 --> 00:03:37,669
what it takes to survive here.

38
00:03:43,869 --> 00:03:46,509
It's the most hostile of them all.

39
00:04:00,949 --> 00:04:04,628
98% of mainland Antarctica,

40
00:04:04,629 --> 00:04:08,468
an area one-and-a-half times the
size of the United States,

41
00:04:08,469 --> 00:04:11,948
is covered in ice

42
00:04:11,949 --> 00:04:14,749
on which virtually
nothing can live.

43
00:04:22,109 --> 00:04:25,949
So life is dependent on the ocean
that surrounds it.

44
00:04:28,589 --> 00:04:30,509
But even the ocean freezes.

45
00:04:33,949 --> 00:04:37,709
Only one mammal can live
this far south.

46
00:04:41,149 --> 00:04:42,948
The Weddell seal.

47
00:04:45,669 --> 00:04:48,548
She has to keep her breathing hole
open

48
00:04:48,549 --> 00:04:51,709
by grinding back the ice
with her teeth.

49
00:05:04,949 --> 00:05:06,948
Out here on the sea ice,

50
00:05:06,949 --> 00:05:11,269
all these seals are far from the
predators of the open ocean.

51
00:05:12,869 --> 00:05:16,909
So, this is the safest place
for her to give birth.

52
00:05:19,389 --> 00:05:22,628
Leaving the warmth of the womb
and landing on ice

53
00:05:22,629 --> 00:05:27,109
is the sharpest drop in temperature
any animal ever faces.

54
00:05:36,669 --> 00:05:41,309
But her pup can't swim for the first
ten days of its life.

55
00:05:46,429 --> 00:05:48,388
It's trapped here

56
00:05:48,389 --> 00:05:49,629
out on the ice.

57
00:06:10,669 --> 00:06:12,709
She shields her pup from the wind.

58
00:06:15,309 --> 00:06:18,988
Although in spring,
temperatures can drop

59
00:06:18,989 --> 00:06:21,548
to minus 40 degrees Celsius,

60
00:06:21,549 --> 00:06:23,749
and blizzards can rage for days.

61
00:06:47,469 --> 00:06:50,869
Three days on, and the storm
is still raging.

62
00:06:53,029 --> 00:06:55,829
She now faces the hardest
of decisions.

63
00:07:02,229 --> 00:07:03,748
Does she stay with her pup?

64
00:07:10,349 --> 00:07:12,069
Or shelter in the water?

65
00:07:35,189 --> 00:07:38,708
Now, her pup's best chance
of survival

66
00:07:38,709 --> 00:07:41,429
is for the storm to pass quickly.

67
00:08:04,845 --> 00:08:06,925
Some pups didn't make it.

68
00:08:19,485 --> 00:08:20,485
An answer.

69
00:08:36,365 --> 00:08:40,604
If this pup now joins its mother
in the water,

70
00:08:40,605 --> 00:08:42,244
it will be safe

71
00:08:42,245 --> 00:08:43,845
from any future storm.

72
00:08:52,365 --> 00:08:55,524
It's minus two degrees Celsius,

73
00:08:55,525 --> 00:08:58,004
but being in water is warmer

74
00:08:58,005 --> 00:08:59,684
than lying on the ice

75
00:08:59,685 --> 00:09:01,125
in the howling wind.

76
00:09:06,005 --> 00:09:10,445
Its chances of surviving
here are now extremely good.

77
00:09:22,285 --> 00:09:27,525
Only a few hardy animals can live
all year round as far south as this.

78
00:09:30,565 --> 00:09:31,964
Further from the pole,

79
00:09:31,965 --> 00:09:33,764
on the fringes of the continent,

80
00:09:33,765 --> 00:09:36,645
lie islands
that are free of sea ice.

81
00:09:42,405 --> 00:09:45,205
Here, there are other challenges.

82
00:09:50,765 --> 00:09:53,364
St Andrews Bay on South Georgia

83
00:09:53,365 --> 00:09:56,565
is packed with half
a million king penguins.

84
00:10:05,125 --> 00:10:08,124
In spring, the chicks are left
for days,

85
00:10:08,125 --> 00:10:10,444
while their parents are away

86
00:10:10,445 --> 00:10:12,285
collecting food for them.

87
00:10:14,445 --> 00:10:17,524
There is a simple arrangement.

88
00:10:17,525 --> 00:10:20,644
The chicks must stay exactly
where their parents left them

89
00:10:20,645 --> 00:10:22,925
to be sure of being found again.

90
00:10:34,365 --> 00:10:37,725
But this chick has
decided to look around.

91
00:10:46,885 --> 00:10:49,405
There is a lot to be investigated.

92
00:11:33,445 --> 00:11:35,524
But it must not stray too far

93
00:11:35,525 --> 00:11:37,325
from its meeting place.

94
00:11:41,765 --> 00:11:43,204
This parent has returned

95
00:11:43,205 --> 00:11:44,525
with food in its crop.

96
00:11:46,085 --> 00:11:48,685
But its chick isn't where
it left it.

97
00:11:52,525 --> 00:11:53,764
It's hard to stay put

98
00:11:53,765 --> 00:11:55,925
when there's so much to play with.

99
00:12:00,205 --> 00:12:02,085
Elephant seals are here, too.

100
00:12:05,965 --> 00:12:07,284
Very mysterious.

101
00:12:33,245 --> 00:12:35,604
Finding it
in the crowd of youngsters

102
00:12:35,605 --> 00:12:37,285
is not going to be easy.

103
00:12:38,765 --> 00:12:41,125
They must recognise each other
by their calls.

104
00:12:47,445 --> 00:12:50,284
But to hear these in such
a noisy colony,

105
00:12:50,285 --> 00:12:52,724
then they must be within
15 metres of each other.

106
00:13:23,365 --> 00:13:24,765
Reunited.

107
00:13:35,965 --> 00:13:40,524
St Andrews Beach is one
of the most crowded on the planet,

108
00:13:40,525 --> 00:13:43,685
and so holding a territory
here is a constant battle.

109
00:13:48,565 --> 00:13:51,004
This bull elephant seal holds

110
00:13:51,005 --> 00:13:54,445
the mating rights to 60 females.

111
00:13:58,565 --> 00:14:02,445
For two months, he's guarded
this stretch of beach.

112
00:14:03,965 --> 00:14:05,204
Unable to feed,

113
00:14:05,205 --> 00:14:08,324
he's losing ten kilos a day,

114
00:14:08,325 --> 00:14:10,525
and he's exhausted.

115
00:14:14,445 --> 00:14:16,764
But other bulls are lying around,

116
00:14:16,765 --> 00:14:18,405
waiting their chance.

117
00:15:27,725 --> 00:15:30,324
Blubber, 15 centimetres thick,

118
00:15:30,325 --> 00:15:32,964
is protection against the cold,

119
00:15:32,965 --> 00:15:34,564
but not from the impact

120
00:15:34,565 --> 00:15:36,405
of a four-tonne opponent.

121
00:16:05,645 --> 00:16:07,044
He holds his ground

122
00:16:07,045 --> 00:16:09,044
and forces the intruder

123
00:16:09,045 --> 00:16:10,245
back out to sea.

124
00:16:19,485 --> 00:16:22,125
Life in the Antarctic is harsh
indeed.

125
00:16:23,365 --> 00:16:25,564
But all these creatures come here

126
00:16:25,565 --> 00:16:27,324
because the Southern Ocean

127
00:16:27,325 --> 00:16:29,205
is one of the richest on Earth.

128
00:16:32,885 --> 00:16:34,724
When, 30 million years ago,

129
00:16:34,725 --> 00:16:36,564
the continent broke away

130
00:16:36,565 --> 00:16:39,404
from South America and drifted
south,

131
00:16:39,405 --> 00:16:42,085
currents began to swirl
right around it.

132
00:16:48,525 --> 00:16:50,124
They are now the strongest

133
00:16:50,125 --> 00:16:51,965
of any currents on the planet.

134
00:16:58,485 --> 00:17:01,124
They sweep up nutrients
from the depths,

135
00:17:01,125 --> 00:17:04,364
and so create one of
the richest feeding grounds

136
00:17:04,365 --> 00:17:06,325
in all the world's oceans.

137
00:17:10,805 --> 00:17:12,244
And some of the creatures

138
00:17:12,245 --> 00:17:13,524
that come here to feast

139
00:17:13,525 --> 00:17:16,285
do so in a most sophisticated way.

140
00:17:35,845 --> 00:17:37,485
Humpback whales.

141
00:17:41,725 --> 00:17:43,964
It's summer, and they've come here

142
00:17:43,965 --> 00:17:45,205
for a banquet.

143
00:18:01,645 --> 00:18:03,484
The cold waters contain

144
00:18:03,485 --> 00:18:05,725
great shoals of krill.

145
00:18:08,165 --> 00:18:12,364
It's estimated that there are 400
trillion of them

146
00:18:12,365 --> 00:18:15,724
and that their combined weight is
greater than that of any other

147
00:18:15,725 --> 00:18:17,885
animal species on the planet.

148
00:18:22,325 --> 00:18:26,044
To collect them, the humpbacks blow
curtains of bubbles,

149
00:18:26,045 --> 00:18:28,645
which the krill won't cross.

150
00:18:36,005 --> 00:18:41,365
The whales then rise, spiralling
inwards, to concentrate the swarm.

151
00:18:54,645 --> 00:18:58,564
Summer in Antarctica is a time of
plenty,

152
00:18:58,565 --> 00:19:02,164
when most humpbacks are able to put
on the reserves they need

153
00:19:02,165 --> 00:19:04,445
for the whole year.

154
00:19:07,485 --> 00:19:11,725
But the wildlife in these waters
faces an uncertain future.

155
00:19:16,805 --> 00:19:19,445
The Southern Ocean is warming.

156
00:19:25,645 --> 00:19:30,044
90% of the world's ice lies in
Antarctica

157
00:19:30,045 --> 00:19:32,844
and, in some parts, the rate at
which it's melting

158
00:19:32,845 --> 00:19:35,485
is doubling every decade.

159
00:19:38,125 --> 00:19:40,565
Sea levels are rising.

160
00:19:42,245 --> 00:19:45,245
But there is a more immediate
threat.

161
00:19:47,765 --> 00:19:52,204
The warming of the coldest region on
Earth is having a profound effect

162
00:19:52,205 --> 00:19:54,445
on global weather patterns.

163
00:19:56,045 --> 00:20:01,045
And this change in the climate is
already being felt right here.

164
00:20:05,765 --> 00:20:09,805
This grey-headed albatross chick is
four weeks old.

165
00:20:12,485 --> 00:20:16,804
So far, it has been sheltered from
the gales by its parents,

166
00:20:16,805 --> 00:20:20,165
who take turns to collect food for
it out at sea.

167
00:20:26,285 --> 00:20:30,724
It is the only chick that they
will have in two years.

168
00:20:38,685 --> 00:20:42,565
The delicate touching of beaks
strengthens their bond.

169
00:21:02,445 --> 00:21:06,165
But these tender moments cannot last
forever.

170
00:21:11,565 --> 00:21:15,444
As a chick grows, so does its
appetite.

171
00:21:15,445 --> 00:21:19,885
So one parent has to leave to find
food before the other returns.

172
00:21:23,965 --> 00:21:28,724
Parting is a big step
and they take time over it.

173
00:22:05,365 --> 00:22:09,605
For the first time in its life,
this chick is alone.

174
00:22:19,165 --> 00:22:23,364
The Antarctic is the windiest
continent,

175
00:22:23,365 --> 00:22:27,364
and in recent years, climate change
has brought storms

176
00:22:27,365 --> 00:22:30,365
that are more frequent and even more
powerful.

177
00:22:40,005 --> 00:22:43,765
Winds now regularly reach 70mph.

178
00:22:51,005 --> 00:22:54,965
But the albatross chicks must try to
stay on their nests.

179
00:23:48,765 --> 00:23:51,525
Surviving the storm is one thing...

180
00:23:53,405 --> 00:23:57,324
..but now, off the nest in these
freezing temperatures,

181
00:23:57,325 --> 00:24:00,325
this chick has just hours to live.

182
00:24:12,245 --> 00:24:15,645
The brutal conditions have taken
their toll.

183
00:24:19,645 --> 00:24:23,005
Some chicks have already succumbed
to exposure.

184
00:24:34,405 --> 00:24:39,525
The bond is so strong, it can be
hard for a father to let go.

185
00:24:44,485 --> 00:24:47,644
The albatross population here has
more than halved

186
00:24:47,645 --> 00:24:50,245
in the last 15 years.

187
00:24:53,805 --> 00:24:57,285
These albatross are facing
extinction.

188
00:24:59,285 --> 00:25:02,524
They simply cannot keep pace with
the changes

189
00:25:02,525 --> 00:25:05,165
affecting their world.

190
00:25:26,325 --> 00:25:29,805
More parents are returning to the
colony.

191
00:25:40,285 --> 00:25:42,925
Something is not right.

192
00:25:46,005 --> 00:25:48,805
The nest should not be empty.

193
00:25:59,045 --> 00:26:03,084
The chick is actually right below
its parent,

194
00:26:03,085 --> 00:26:07,565
but because it's not on the nest,
the parent doesn't recognise it.

195
00:26:17,205 --> 00:26:19,525
And doesn't help it.

196
00:26:24,205 --> 00:26:29,244
Strangely, perhaps, these albatross
do not recognise their chicks

197
00:26:29,245 --> 00:26:32,005
by sight, sound or smell.

198
00:26:33,565 --> 00:26:37,205
They identify them by finding them
on the nest.

199
00:26:40,845 --> 00:26:44,644
So, these violent storms have
created a problem

200
00:26:44,645 --> 00:26:48,245
that the albatross are not equipped
to solve.

201
00:26:56,565 --> 00:27:01,124
If it is to survive, the chick will
have to get back on the nest

202
00:27:01,125 --> 00:27:03,805
by itself.

203
00:28:01,285 --> 00:28:03,525
The chick has made it.

204
00:28:05,885 --> 00:28:09,284
The bond is re-established
immediately

205
00:28:09,285 --> 00:28:13,524
and its parent, once again, provides
the warmth that the chick

206
00:28:13,525 --> 00:28:15,804
so desperately needs.

207
00:28:23,845 --> 00:28:26,845
It's safe... for now.

208
00:28:48,005 --> 00:28:52,045
Nowhere in Antarctica is
survival easy.

209
00:28:54,325 --> 00:28:58,164
Gentoo penguins travel up to 50
miles every day

210
00:28:58,165 --> 00:29:00,524
to find food.

211
00:29:00,525 --> 00:29:03,245
And they're now returning to their
chicks.

212
00:29:05,245 --> 00:29:07,884
They are the fastest penguin
in the sea

213
00:29:07,885 --> 00:29:10,725
and can swim at 22mph.

214
00:29:13,725 --> 00:29:16,965
But other animals can swim much
faster.

215
00:29:26,285 --> 00:29:28,685
Orca.

216
00:29:41,445 --> 00:29:44,885
This penguin must
rely on its agility.

217
00:31:06,365 --> 00:31:11,205
With four orcas chasing it, the
penguin stood little chance.

218
00:31:39,245 --> 00:31:43,285
Most gentoo parents do make it back
to the colony.

219
00:31:47,085 --> 00:31:50,525
Today, it's been a good hunt for
krill.

220
00:31:53,645 --> 00:31:56,165
Perhaps too good.

221
00:31:58,805 --> 00:32:02,764
The chicks grow and it seems that
the Mohawk style

222
00:32:02,765 --> 00:32:04,805
is back in fashion.

223
00:32:07,085 --> 00:32:09,284
It's just a phase.

224
00:32:09,285 --> 00:32:11,325
He'll grow out of it.

225
00:32:14,205 --> 00:32:18,284
He'll soon lose these remaining down
feathers and be ready to leave

226
00:32:18,285 --> 00:32:21,285
the colony and collect food for
himself.

227
00:32:22,365 --> 00:32:27,605
But doing so is becoming harder
because of climate change.

228
00:32:34,165 --> 00:32:37,404
Glaciers in the region are now
calving faster

229
00:32:37,405 --> 00:32:40,805
than they have done since records
began.

230
00:32:47,685 --> 00:32:51,285
And this brash ice now fills the
bays.

231
00:33:01,925 --> 00:33:04,005
It's autumn.

232
00:33:06,205 --> 00:33:10,645
The chicks have lost their down
feathers and they're hungry.

233
00:33:11,965 --> 00:33:15,524
They must go to
sea for the first time.

234
00:33:18,965 --> 00:33:23,005
But now there's a risk of being
crushed between blocks of ice.

235
00:33:28,965 --> 00:33:32,125
They have to get to the distant
icebergs...

236
00:33:34,885 --> 00:33:38,445
..and so reach the open ocean that
lies beyond.

237
00:33:42,125 --> 00:33:44,965
And that is easier said than done.

238
00:33:54,485 --> 00:33:56,765
A leopard seal...

239
00:33:58,125 --> 00:34:00,285
..their main predator.

240
00:34:01,605 --> 00:34:04,565
It's a giant, three metres long.

241
00:34:06,925 --> 00:34:10,965
These icy conditions help
it to hunt.

242
00:34:19,205 --> 00:34:22,525
The penguins can neither
walk nor swim.

243
00:34:32,525 --> 00:34:36,564
They have no way of telling
where the seal will strike.

244
00:35:13,765 --> 00:35:16,605
These are easy pickings.

245
00:35:28,365 --> 00:35:31,205
For some, it's time to retreat.

246
00:36:07,205 --> 00:36:10,205
But now, it's back to square one.

247
00:36:14,525 --> 00:36:19,685
There's no alternative
but to run the gauntlet once again.

248
00:36:53,245 --> 00:36:57,045
The seal seems to be toying with
this penguin.

249
00:37:00,125 --> 00:37:02,885
But safety is in sight.

250
00:37:19,685 --> 00:37:22,565
The ice floe is near the open ocean.

251
00:37:26,165 --> 00:37:29,125
But this penguin is exhausted.

252
00:38:08,925 --> 00:38:11,885
Perhaps it's not worth it, after
all.

253
00:38:37,245 --> 00:38:39,645
Winter is coming.

254
00:38:43,605 --> 00:38:47,845
Antarctica now undergoes a major
transformation.

255
00:38:50,525 --> 00:38:55,365
Every day, 40,000 more square miles
of sea freeze over.

256
00:38:58,205 --> 00:39:02,245
By the end of winter, the continent
has doubled in size.

257
00:39:04,965 --> 00:39:09,045
This is by far the largest
desert in the world.

258
00:39:26,845 --> 00:39:31,285
But the frozen surface of the sea
hides a great secret.

259
00:39:39,845 --> 00:39:43,724
It may be hostile above the ice,
but below it,

260
00:39:43,725 --> 00:39:47,444
conditions are so stable that life
over millennia

261
00:39:47,445 --> 00:39:50,045
has had time to diversify.

262
00:39:54,925 --> 00:39:58,444
Creatures here grow to a great size.

263
00:39:58,445 --> 00:40:01,845
Predatory nemertean worms are three
metres long.

264
00:40:05,885 --> 00:40:09,685
These dramas only become visible
when speeded up.

265
00:40:14,525 --> 00:40:18,244
We're only just beginning to
discover the details of the lives

266
00:40:18,245 --> 00:40:20,845
of such strange creatures.

267
00:40:25,805 --> 00:40:28,645
Nudibranchs are hermaphrodites.

268
00:40:31,525 --> 00:40:36,924
Each individual possesses both male
and female reproductive organs.

269
00:40:36,925 --> 00:40:39,964
So, to mate, one nudibranch
just needs to find

270
00:40:39,965 --> 00:40:42,244
another nudibranch.

271
00:40:42,245 --> 00:40:44,645
And any one will do.

272
00:40:46,845 --> 00:40:51,325
But nonetheless, this is a challenge
when their tiny eyes can barely see.

273
00:41:04,725 --> 00:41:07,325
Some do get lucky.

274
00:41:15,525 --> 00:41:19,965
They're fertilising each other and
both will produce young.

275
00:41:27,325 --> 00:41:31,084
When it's hard to find a partner,
it pays not to have to worry

276
00:41:31,085 --> 00:41:33,405
about your gender.

277
00:41:43,365 --> 00:41:48,324
Sea anemones may look like plants,
but, actually, are animals

278
00:41:48,325 --> 00:41:52,084
and feed by catching edible
particles that drift within reach

279
00:41:52,085 --> 00:41:54,285
of their tentacles.

280
00:41:57,365 --> 00:42:02,285
But being rooted to the sea floor
makes them vulnerable to predators.

281
00:42:05,725 --> 00:42:10,765
An ocean-going jellyfish, a metre
or so across, searching for food.

282
00:42:24,965 --> 00:42:27,525
The jellyfish senses prey.

283
00:42:49,285 --> 00:42:53,004
But it's the sea anemones that have
made the catch

284
00:42:53,005 --> 00:42:55,725
and they've grabbed a monster.

285
00:43:07,405 --> 00:43:10,845
A rare feast for these stationary
predators.

286
00:43:16,445 --> 00:43:20,445
They devour their catch over the
next four days.

287
00:43:33,205 --> 00:43:38,045
Life here under the ice has remained
unchanged for millennia.

288
00:43:39,445 --> 00:43:43,964
But in the last 200 years,
much of Antarctica's wildlife

289
00:43:43,965 --> 00:43:47,045
has had to face new predators...

290
00:43:50,685 --> 00:43:52,684
..human beings.

291
00:43:55,485 --> 00:43:59,884
We devised new hunting techniques
and used them so mercilessly

292
00:43:59,885 --> 00:44:03,285
that we almost exterminated the
great whales.

293
00:44:06,445 --> 00:44:10,244
These whaling stations on
South Georgia were at the centre

294
00:44:10,245 --> 00:44:12,525
of this industry.

295
00:44:22,805 --> 00:44:26,444
More than one-and-a-half million
whales were slaughtered

296
00:44:26,445 --> 00:44:29,085
in Antarctic waters.

297
00:44:32,165 --> 00:44:35,524
The blubber was stripped from
their massive bodies

298
00:44:35,525 --> 00:44:40,245
and boiled down in vats to make
margarine and soap.

299
00:44:43,365 --> 00:44:47,284
And the largest animal ever
recorded,

300
00:44:47,285 --> 00:44:53,084
a 33-metre blue whale, perhaps over
100 years old,

301
00:44:53,085 --> 00:44:57,005
was butchered on this ramp in just
two hours.

302
00:45:05,885 --> 00:45:10,484
This reckless slaughter marked a new
low in our relationship

303
00:45:10,485 --> 00:45:13,205
with the natural world.

304
00:45:42,245 --> 00:45:45,445
Southern right whales were hit the
hardest.

305
00:45:49,245 --> 00:45:52,284
They were so trusting and
inquisitive

306
00:45:52,285 --> 00:45:55,565
that they swam right up to the
whalers' boats.

307
00:45:57,885 --> 00:46:01,604
And the whalers called them right
whales

308
00:46:01,605 --> 00:46:04,925
because they were the right
whales to hunt.

309
00:46:13,925 --> 00:46:17,725
Mothers with calves were targeted
first.

310
00:46:20,645 --> 00:46:25,124
To give birth, females came to the
same sheltered bays

311
00:46:25,125 --> 00:46:28,885
and would not leave their calves
alone at the surface.

312
00:46:30,405 --> 00:46:35,484
In just decades,
a population of 35,000

313
00:46:35,485 --> 00:46:40,325
was so reduced that only 35 of the
females survived.

314
00:46:44,765 --> 00:46:47,524
But times have changed.

315
00:46:47,525 --> 00:46:53,124
A ban on the commercial hunting of
whales, introduced in 1986,

316
00:46:53,125 --> 00:46:57,565
has stopped all but Japan, Norway
and Iceland.

317
00:47:02,125 --> 00:47:05,444
Our relationship to these
remarkable creatures

318
00:47:05,445 --> 00:47:08,005
has undergone a huge shift.

319
00:47:10,805 --> 00:47:14,645
Scientists are now learning a great
deal about these whales.

320
00:47:18,925 --> 00:47:22,125
But we still don't know how long
they live.

321
00:47:25,525 --> 00:47:29,044
It's thought that some individuals
alive today

322
00:47:29,045 --> 00:47:32,325
were around at the time of the mass
slaughter.

323
00:47:33,645 --> 00:47:37,004
Yet these 60-tonne whales remain
gentle

324
00:47:37,005 --> 00:47:39,845
and inquisitive around humans.

325
00:47:47,885 --> 00:47:50,964
By putting a stop to commercial
hunting,

326
00:47:50,965 --> 00:47:55,325
this population of whales has now
grown to over 2,000.

327
00:48:18,285 --> 00:48:23,684
The recovery of life in Antarctic
waters may have a significance

328
00:48:23,685 --> 00:48:27,244
that extends far beyond the reaches
of the continent

329
00:48:27,245 --> 00:48:29,685
and will affect us all.

330
00:48:33,685 --> 00:48:37,124
Just off the coast of Elephant
Island,

331
00:48:37,125 --> 00:48:40,404
we have recently witnessed what
might be

332
00:48:40,405 --> 00:48:43,245
the greatest feeding spectacle on
Earth.

333
00:48:47,685 --> 00:48:52,124
On the horizon, over 150 whales
have gathered

334
00:48:52,125 --> 00:48:54,965
to feast on krill.

335
00:49:03,685 --> 00:49:08,325
This is the largest congregation of
great whales ever filmed.

336
00:49:21,165 --> 00:49:25,325
These are mostly fin whales,
up to 26 metres long.

337
00:49:28,445 --> 00:49:31,565
Humpback whales are dwarfed in
comparison.

338
00:49:35,245 --> 00:49:39,004
Thousands of animals from all over
Antarctic waters

339
00:49:39,005 --> 00:49:41,645
are making their way here.

340
00:49:53,525 --> 00:49:58,125
These seas are, once again,
beginning to brim with life.

341
00:50:02,605 --> 00:50:06,764
And scientists have discovered that
the Southern Ocean,

342
00:50:06,765 --> 00:50:10,484
and the life within it, soaks up
more than twice as much

343
00:50:10,485 --> 00:50:14,725
carbon from the atmosphere as the
Amazon rainforest.

344
00:50:24,125 --> 00:50:28,645
By protecting Antarctica, we don't
just protect the life here...

345
00:50:29,885 --> 00:50:33,564
..we are helping to restore the
natural balance

346
00:50:33,565 --> 00:50:36,205
of the entire planet.

347
00:50:59,325 --> 00:51:03,124
St Andrews Bay provides one of the
most spectacular sights

348
00:51:03,125 --> 00:51:05,644
in the whole of the Antarctic.

349
00:51:05,645 --> 00:51:08,404
But to get there, the team will have
to cross

350
00:51:08,405 --> 00:51:12,884
the roughest seas in the world,
and nerves are starting to show.

351
00:51:12,885 --> 00:51:14,924
The wind is picking up already!

352
00:51:17,805 --> 00:51:21,845
It'll take ten days at sea to reach
this remote location.

353
00:51:23,485 --> 00:51:27,325
And it's not long before they start
to feel a bit green.

354
00:51:31,005 --> 00:51:33,244
There's some big waves coming now.

355
00:51:33,245 --> 00:51:38,725
With these conditions lasting days,
all who can take shifts at the helm.

356
00:51:40,525 --> 00:51:44,004
And you get given a talk, to say if
you fall in the water here,

357
00:51:44,005 --> 00:51:47,484
there's nothing anyone can do -
they can't save you.

358
00:51:47,485 --> 00:51:51,084
It's so cold, you'll die in under
a couple of minutes.

359
00:51:51,085 --> 00:51:52,885
Wow!

360
00:51:57,245 --> 00:52:01,244
Below deck,
Rolf hasn't yet found his sea legs.

361
00:52:05,125 --> 00:52:08,404
For me, this is like punishment or
prisoner-ship or whatever.

362
00:52:08,405 --> 00:52:12,244
I mean, I can't understand at all
how people do this voluntarily,

363
00:52:12,245 --> 00:52:16,084
people dream of being on a boat or
sailing or anything.

364
00:52:16,085 --> 00:52:17,644
Look at that.

365
00:52:17,645 --> 00:52:19,724
I mean, look how much the boat is
moving.

366
00:52:19,725 --> 00:52:22,764
I feel like in a washing machine.

367
00:52:22,765 --> 00:52:26,245
The island of South Georgia finally
appears.

368
00:52:30,325 --> 00:52:33,765
It's a relief to step onto solid
land.

369
00:52:37,845 --> 00:52:40,644
Yeah, the seasickness is already
forgotten, to be honest!

370
00:52:40,645 --> 00:52:42,485
But it's all forgotten.

371
00:52:43,485 --> 00:52:46,764
It's just out of this world.

372
00:52:46,765 --> 00:52:49,445
It's so wonderful that these places
still exist.

373
00:52:55,325 --> 00:52:58,925
They will spend the next three weeks
in St Andrews Bay.

374
00:53:00,805 --> 00:53:05,445
Rolf is here to film the king
penguins in this enormous colony.

375
00:53:07,045 --> 00:53:12,124
And Mark must capture the elephant
seals' intense mating season.

376
00:53:16,045 --> 00:53:19,684
On such a crowded beach,
fights can break out anywhere.

377
00:53:24,965 --> 00:53:28,204
Males are up to six metres long
and they are pumped

378
00:53:28,205 --> 00:53:30,205
full of testosterone.

379
00:53:32,325 --> 00:53:37,684
The bulls take little notice of the
crew and will stop at nothing.

380
00:53:37,685 --> 00:53:39,645
Oh, my God!

381
00:54:04,605 --> 00:54:07,164
That went from nothing to being
nearly steam-rollered

382
00:54:07,165 --> 00:54:09,645
by four huge males.

383
00:54:16,045 --> 00:54:21,004
Beyond the chaos of the beach, Rolf
has king penguins in front of him,

384
00:54:21,005 --> 00:54:24,084
and, thankfully, he's smiling again.

385
00:54:24,085 --> 00:54:26,644
I would really call them
the gentleman penguins

386
00:54:26,645 --> 00:54:29,604
because they are very polite,
they're charming,

387
00:54:29,605 --> 00:54:31,404
they have humour.

388
00:54:31,405 --> 00:54:34,724
There's so many funny, lovely
moments.

389
00:54:34,725 --> 00:54:38,404
I absolutely adore these penguins
for that!

390
00:54:38,405 --> 00:54:42,804
But as weeks go by, the reality of
living amongst penguins

391
00:54:42,805 --> 00:54:45,045
comes to the fore.

392
00:54:46,365 --> 00:54:51,044
Every morning, I think,
"Wow, it's stinky!"

393
00:54:51,045 --> 00:54:55,524
But then I realise, these smells
come out of my shoes

394
00:54:55,525 --> 00:54:57,764
and it's myself.

395
00:55:05,445 --> 00:55:10,165
Back on the beach, the team is using
a stabilised camera rig.

396
00:55:11,325 --> 00:55:13,805
They can now react faster to fights.

397
00:55:14,965 --> 00:55:17,284
So far in the shoot, we've seen a
lot of quick fights,

398
00:55:17,285 --> 00:55:19,484
but we haven't
seen some extended fights,

399
00:55:19,485 --> 00:55:23,164
where you see one bull paired

400
00:55:23,165 --> 00:55:25,245
equally against another bull.

401
00:55:26,725 --> 00:55:28,644
These sights are rare.

402
00:55:28,645 --> 00:55:30,844
The team will need to be at the
ready.

403
00:55:30,845 --> 00:55:33,004
Mark, Mark, Mark!

404
00:55:33,005 --> 00:55:35,165
Let's get running.

405
00:55:39,605 --> 00:55:41,645
Oh, hello!

406
00:55:58,925 --> 00:56:01,244
These are two huge, evenly matched
boys.

407
00:56:01,245 --> 00:56:02,604
I know.

408
00:56:02,605 --> 00:56:05,244
Wow, I never thought we'd be this
close to it. I know, nor did I.

409
00:56:05,245 --> 00:56:07,845
This is really tense, we've just got
to watch out.

410
00:56:13,205 --> 00:56:15,165
We got there.

411
00:56:18,445 --> 00:56:21,084
I never thought I'd see it that
close

412
00:56:21,085 --> 00:56:24,204
and be able to move around it, as
this kind of

413
00:56:24,205 --> 00:56:26,444
aggressive ballet is happening.

414
00:56:29,125 --> 00:56:31,205
And it does make you quite tense.

415
00:56:33,085 --> 00:56:37,485
The shoot is going well, but the
crew are noticing worrying signs.

416
00:56:39,725 --> 00:56:42,205
It's a really hot day today.

417
00:56:43,645 --> 00:56:47,244
30 years ago, the front of that
glacier

418
00:56:47,245 --> 00:56:49,884
was right down on the beach.

419
00:56:49,885 --> 00:56:52,964
It's retreated a huge amount.

420
00:56:52,965 --> 00:56:56,804
I don't really know what climate
change is going to mean

421
00:56:56,805 --> 00:57:00,084
for all the wildlife that's living
here.

422
00:57:00,085 --> 00:57:03,444
Parts of the Antarctic are warming
five times faster

423
00:57:03,445 --> 00:57:05,725
than the rest of the world.

424
00:57:07,125 --> 00:57:10,884
If this trend continues, it will
threaten the very existence

425
00:57:10,885 --> 00:57:13,205
of these polar creatures.

426
00:57:16,125 --> 00:57:19,924
On the last day of filming, the team
can't help but reflect

427
00:57:19,925 --> 00:57:23,084
on the future of the wildlife here.

428
00:57:23,085 --> 00:57:26,644
For me, it's emotional because I
know this might have been

429
00:57:26,645 --> 00:57:28,965
a once-in-a-lifetime experience.

430
00:57:30,165 --> 00:57:33,725
I will definitely take big memories
with me and I will be sad.

431
00:57:35,885 --> 00:57:38,725
It's a really special place,
you know? So...

432
00:57:40,485 --> 00:57:42,565
I don't know.

433
00:57:45,165 --> 00:57:48,805
I just hope we can keep these
places.

434
00:57:50,005 --> 00:57:52,085
And protect them.

435
00:58:08,125 --> 00:58:10,364
Next time...

436
00:58:10,365 --> 00:58:12,925
..the largest continent on Earth.

437
00:58:16,405 --> 00:58:19,164
A world of extremes...

438
00:58:19,165 --> 00:58:22,885
..where rarely seen animals roam the
land...

439
00:58:29,645 --> 00:58:31,845
..Asia.
