1
00:00:00,750 --> 00:00:04,059
I'm a very lucky person.

2
00:00:04,059 --> 00:00:08,537
I've been privileged to see so much of our beautiful Earth

3
00:00:08,537 --> 00:00:10,865
and the people and creatures that live on it.

4
00:00:10,865 --> 00:00:14,485
And my passion was inspired at the age of seven,

5
00:00:14,485 --> 00:00:16,820
when my parents first took me to Morocco,

6
00:00:16,820 --> 00:00:18,946
at the edge of the Sahara Desert.

7
00:00:18,946 --> 00:00:21,321
Now imagine a little Brit

8
00:00:21,321 --> 00:00:24,442
somewhere that wasn't cold and damp like home.

9
00:00:24,442 --> 00:00:26,718
What an amazing experience.

10
00:00:26,718 --> 00:00:29,211
And it made me want to explore more.

11
00:00:29,211 --> 00:00:31,814
So as a filmmaker,

12
00:00:31,814 --> 00:00:34,625
I've been from one end of the Earth to the other

13
00:00:34,625 --> 00:00:37,333
trying to get the perfect shot

14
00:00:37,333 --> 00:00:41,125
and to capture animal behavior never seen before.

15
00:00:41,125 --> 00:00:43,757
And what's more, I'm really lucky,

16
00:00:43,757 --> 00:00:46,875
because I get to share that with millions of people worldwide.

17
00:00:46,875 --> 00:00:52,125
Now the idea of having new perspectives of our planet

18
00:00:52,125 --> 00:00:55,958
and actually being able to get that message out

19
00:00:55,958 --> 00:00:58,816
gets me out of bed every day with a spring in my step.

20
00:00:58,816 --> 00:01:01,958
You might think that it's quite hard

21
00:01:01,958 --> 00:01:04,208
to find new stories and new subjects,

22
00:01:04,208 --> 00:01:08,539
but new technology is changing the way we can film.

23
00:01:08,539 --> 00:01:12,375
It's enabling us to get fresh, new images

24
00:01:12,375 --> 00:01:14,492
and tell brand new stories.

25
00:01:14,492 --> 00:01:17,375
In Nature's Great Events,

26
00:01:17,375 --> 00:01:20,917
a series for the BBC that I did with David Attenborough,

27
00:01:20,917 --> 00:01:23,167
we wanted to do just that.

28
00:01:23,167 --> 00:01:26,208
Images of grizzly bears are pretty familiar.

29
00:01:26,208 --> 00:01:29,458
You see them all the time, you think.

30
00:01:29,458 --> 00:01:33,542
But there's a whole side to their lives that we hardly ever see

31
00:01:33,542 --> 00:01:35,250
and had never been filmed.

32
00:01:35,250 --> 00:01:39,500
So what we did, we went to Alaska,

33
00:01:39,500 --> 00:01:41,868
which is where the grizzlies rely

34
00:01:41,868 --> 00:01:44,854
on really high, almost inaccessible, mountain slopes

35
00:01:44,854 --> 00:01:46,789
for their denning.

36
00:01:46,789 --> 00:01:52,137
And the only way to film that is a shoot from the air.

37
00:01:54,304 --> 00:01:58,917
(Video) David Attenborough: Throughout Alaska and British Columbia,

38
00:01:58,917 --> 00:02:04,129
thousands of bear families are emerging from their winter sleep.

39
00:02:04,129 --> 00:02:08,083
There is nothing to eat up here,

40
00:02:08,083 --> 00:02:11,583
but the conditions were ideal for hibernation.

41
00:02:11,583 --> 00:02:17,014
Lots of snow in which to dig a den.

42
00:02:19,450 --> 00:02:25,440
To find food, mothers must lead their cubs down to the coast,

43
00:02:25,440 --> 00:02:28,292
where the snow will already be melting.

44
00:02:32,502 --> 00:02:39,650
But getting down can be a challenge for small cubs.

45
00:03:05,723 --> 00:03:09,458
These mountains are dangerous places,

46
00:03:09,458 --> 00:03:12,917
but ultimately the fate of these bear families,

47
00:03:12,917 --> 00:03:16,431
and indeed that of all bears around the North Pacific,

48
00:03:16,431 --> 00:03:21,048
depends on the salmon.

49
00:03:21,064 --> 00:03:23,625
KB: I love that shot.

50
00:03:23,625 --> 00:03:25,917
I always get goosebumps every time I see it.

51
00:03:25,917 --> 00:03:27,958
That was filmed from a helicopter

52
00:03:27,958 --> 00:03:30,750
using a gyro-stabilized camera.

53
00:03:30,750 --> 00:03:33,208
And it's a wonderful bit of gear,

54
00:03:33,208 --> 00:03:37,167
because it's like having a flying tripod, crane and dolly all rolled into one.

55
00:03:37,167 --> 00:03:40,375
But technology alone isn't enough.

56
00:03:40,375 --> 00:03:42,875
To really get the money shots,

57
00:03:42,875 --> 00:03:45,917
it's down to being in the right place at the right time.

58
00:03:45,917 --> 00:03:48,875
And that sequence was especially difficult.

59
00:03:48,875 --> 00:03:52,375
The first year we got nothing.

60
00:03:52,375 --> 00:03:55,958
We had to go back the following year,

61
00:03:55,958 --> 00:03:58,958
all the way back to the remote parts of Alaska.

62
00:03:58,958 --> 00:04:01,583
And we hung around with a helicopter for two whole weeks.

63
00:04:01,583 --> 00:04:04,625
And eventually we got lucky.

64
00:04:04,625 --> 00:04:08,958
The cloud lifted, the wind was still,

65
00:04:08,958 --> 00:04:10,708
and even the bear showed up.

66
00:04:10,708 --> 00:04:13,292
And we managed to get that magic moment.

67
00:04:13,292 --> 00:04:15,167
For a filmmaker,

68
00:04:15,167 --> 00:04:19,340
new technology is an amazing tool,

69
00:04:19,340 --> 00:04:22,546
but the other thing that really, really excites me

70
00:04:22,546 --> 00:04:25,500
is when new species are discovered.

71
00:04:25,500 --> 00:04:27,787
Now, when I heard about one animal,

72
00:04:27,787 --> 00:04:30,750
I knew we had to get it for my next series,

73
00:04:30,750 --> 00:04:33,500
Untamed Americas, for National Geographic.

74
00:04:33,500 --> 00:04:39,811
In 2005, a new species of bat was discovered

75
00:04:39,811 --> 00:04:42,083
in the cloud forests of Ecuador.

76
00:04:42,083 --> 00:04:44,167
And what was amazing about that discovery

77
00:04:44,167 --> 00:04:46,583
is that it also solved the mystery

78
00:04:46,583 --> 00:04:49,620
of what pollinated a unique flower.

79
00:04:49,620 --> 00:04:51,583
It depends solely on the bat.

80
00:04:51,583 --> 00:04:54,317
Now, the series hasn't even aired yet,

81
00:04:54,317 --> 00:04:56,744
so you're the very first to see this.

82
00:04:56,744 --> 00:04:57,859
See what you think.

83
00:05:01,590 --> 00:05:07,548
(Video) Narrator: The tube-lipped nectar bat.

84
00:05:10,536 --> 00:05:12,877
A pool of delicious nectar

85
00:05:12,877 --> 00:05:15,042
lies at the bottom of each flower's long flute.

86
00:05:15,042 --> 00:05:19,887
But how to reach it?

87
00:05:19,887 --> 00:05:25,083
Necessity is the mother of evolution.

88
00:05:25,083 --> 00:05:48,489
(Music)

89
00:05:48,489 --> 00:05:51,496
This two-and-a-half-inch bat

90
00:05:51,496 --> 00:05:58,221
has a three-and-a-half-inch tongue,

91
00:05:58,221 --> 00:06:02,119
the longest relative to body length

92
00:06:02,119 --> 00:06:04,438
of any mammal in the world.

93
00:06:04,438 --> 00:06:11,577
If human, he'd have a nine-foot tongue.

94
00:06:16,122 --> 00:06:18,612
(Applause)

95
00:06:18,612 --> 00:06:20,677
KB: What a tongue.

96
00:06:20,677 --> 00:06:25,542
We filmed it by cutting a tiny little hole in the base of the flower

97
00:06:25,542 --> 00:06:30,167
and using a camera that could slow the action by 40 times.

98
00:06:30,167 --> 00:06:33,250
So imagine how quick that thing is in real life.

99
00:06:33,250 --> 00:06:38,462
Now people often ask me, "Where's your favorite place on the planet?"

100
00:06:38,462 --> 00:06:40,995
And the truth is I just don't have one.

101
00:06:40,995 --> 00:06:43,542
There are so many wonderful places.

102
00:06:43,542 --> 00:06:47,042
But some locations draw you back time and time again.

103
00:06:47,042 --> 00:06:49,790
And one remote location --

104
00:06:49,790 --> 00:06:51,810
I first went there as a backpacker;

105
00:06:51,810 --> 00:06:54,125
I've been back several times for filming,

106
00:06:54,125 --> 00:06:55,875
most recently for Untamed Americas --

107
00:06:55,875 --> 00:07:00,625
it's the Altiplano in the high Andes of South America,

108
00:07:00,625 --> 00:07:05,792
and it's the most otherworldly place I know.

109
00:07:05,792 --> 00:07:08,894
But at 15,000 feet, it's tough.

110
00:07:08,894 --> 00:07:10,417
It's freezing cold,

111
00:07:10,417 --> 00:07:15,083
and that thin air really gets you.

112
00:07:15,083 --> 00:07:17,394
Sometimes it's hard to breathe,

113
00:07:17,394 --> 00:07:20,437
especially carrying all the heavy filming equipment.

114
00:07:20,437 --> 00:07:25,042
And that pounding head just feels like a constant hangover.

115
00:07:25,042 --> 00:07:29,333
But the advantage of that wonderful thin atmosphere

116
00:07:29,333 --> 00:07:33,271
is that it enables you to see the stars in the heavens

117
00:07:33,271 --> 00:07:35,710
with amazing clarity.

118
00:07:35,710 --> 00:07:39,896
Have a look.

119
00:07:39,896 --> 00:07:43,552
(Video) Narrator: Some 1,500 miles south of the tropics,

120
00:07:43,552 --> 00:07:45,237
between Chile and Bolivia,

121
00:07:45,237 --> 00:07:50,413
the Andes completely change.

122
00:07:50,413 --> 00:07:55,042
It's called the Altiplano, or "high plains" --

123
00:07:55,042 --> 00:07:58,925
a place of extremes

124
00:07:58,925 --> 00:08:02,614
and extreme contrasts.

125
00:08:02,614 --> 00:08:07,125
Where deserts freeze

126
00:08:07,125 --> 00:08:10,958
and waters boil.

127
00:08:10,958 --> 00:08:14,458
More like Mars than Earth,

128
00:08:14,458 --> 00:08:16,881
it seems just as hostile to life.

129
00:08:25,196 --> 00:08:28,865
The stars themselves --

130
00:08:35,065 --> 00:08:38,786
at 12,000 feet, the dry, thin air

131
00:08:38,786 --> 00:08:46,929
makes for perfect stargazing.

132
00:08:46,929 --> 00:08:52,813
Some of the world's astronomers have telescopes nearby.

133
00:08:52,813 --> 00:08:56,885
But just looking up with the naked eye,

134
00:08:56,885 --> 00:09:00,130
you really don't need one.

135
00:09:00,130 --> 00:09:47,140

136
00:09:47,140 --> 00:09:53,167
