Coral reef adventure
3
00:01:07,674 --> 00:01:10,721
the south Pacific
4
00:01:10,762 --> 00:01:15,073
lagoons that hint paradise
5
00:01:15,268 --> 00:01:17,146
magnificent coral reefs that
6
00:01:17,187 --> 00:01:22,097
light the dream in corners of minds
7
00:01:23,780 --> 00:01:28,453
this is the world as we wish and could always be
8
00:01:57,702 --> 00:02:00,039
in this great corner of life
9
00:02:00,122 --> 00:02:03,877
thousands of colorful characters coexist
10
00:02:03,919 --> 00:02:06,840
diversities strengthens coral reefs
11
00:02:06,881 --> 00:02:08,258
the more species
12
00:02:08,301 --> 00:02:11,113
the more survival systems
13
00:02:11,305 --> 00:02:16,889
coral reefs be going strong for sixty million years
14
00:02:17,689 --> 00:02:21,569
some corals wave like flowers in the breath
15
00:02:21,610 --> 00:02:25,199
others masquerade the stones
16
00:02:25,240 --> 00:02:29,130
but all corals are animals
17
00:02:32,792 --> 00:02:36,631
this under order playgrounds are built by hard corals
18
00:02:36,672 --> 00:02:40,876
which produce lime stone and turn it into homes
19
00:02:41,346 --> 00:02:43,766
stack one on top of the other
20
00:02:43,807 --> 00:02:45,227
millions of coral homes
21
00:02:45,268 --> 00:02:49,839
gradually form a gigantic reef
22
00:02:51,568 --> 00:02:55,073
how wonderful the largest living structures on earth
23
00:02:55,116 --> 00:03:01,332
are built by tiny animals
24
00:03:05,881 --> 00:03:09,051
coral reefs protect nearly all tropical coast
25
00:03:09,135 --> 00:03:13,758
standing between islander's homes and violent seas
26
00:03:27,827 --> 00:03:28,870
one may injured
27
00:03:28,913 --> 00:03:31,917
doctors use calcium carbonate from coral
28
00:03:31,958 --> 00:03:34,796
to mend our broken bones
29
00:03:34,837 --> 00:03:36,214
when we were sick
30
00:03:36,255 --> 00:03:38,008
chemical components from the reef
31
00:03:38,050 --> 00:03:41,471
may restore our health
32
00:03:41,513 --> 00:03:42,723
no place on earth
33
00:03:42,764 --> 00:03:46,677
holds greater potential for medical curers
34
00:03:49,148 --> 00:03:49,899
reefs
35
00:03:49,942 --> 00:03:51,151
feeders
36
00:03:51,194 --> 00:03:53,112
over three hundred million people
37
00:03:53,196 --> 00:03:56,216
rely on fish from reefs
38
00:03:57,159 --> 00:03:59,831
for Pacific islander like me
39
00:03:59,872 --> 00:04:04,648
our coral reefs are as necessary as the air we breath
40
00:04:14,100 --> 00:04:17,062
Russy coral a native of Fiji
41
00:04:17,105 --> 00:04:20,391
has always lived close to the sea
42
00:04:26,784 --> 00:04:27,995
for centuries
43
00:04:28,036 --> 00:04:30,915
my ancestors were careful not to overfish
44
00:04:30,956 --> 00:04:33,585
so our reef was healthy
45
00:04:33,628 --> 00:04:34,754
but this year
46
00:04:34,795 --> 00:04:37,090
something happened
47
00:04:37,132 --> 00:04:39,642
something terrible
48
00:04:43,849 --> 00:04:47,900
a blacker death set over the reef
49
00:04:51,360 --> 00:04:54,116
what was killing our reef?
50
00:05:00,540 --> 00:05:04,671
I made up my mind to find the answers
51
00:05:04,712 --> 00:05:06,255
I decide to reach up to
52
00:05:06,298 --> 00:05:09,916
some of my death partners around the world
53
00:05:10,637 --> 00:05:12,514
Howard and Micheal Hall
54
00:05:12,557 --> 00:05:16,312
has spent thirty years exploring and filming reefs
55
00:05:16,353 --> 00:05:20,108
their underwater photography is world known
56
00:05:20,150 --> 00:05:22,821
when Howard and Micheal got Russy's message
57
00:05:22,904 --> 00:05:24,239
they voyaged the mountains
58
00:05:24,280 --> 00:05:27,437
far from the reefs they loved
59
00:05:37,674 --> 00:05:39,636
I was drawing that flight I kept wondering
60
00:05:39,677 --> 00:05:42,306
what we could do to help Russy
61
00:05:42,348 --> 00:05:43,641
then I realized that
62
00:05:43,682 --> 00:05:45,894
our friend Richard Pile might know what to do
63
00:05:45,978 --> 00:05:48,350
he is a marine biologist
64
00:05:48,564 --> 00:05:50,692
across the world
65
00:05:50,735 --> 00:05:54,447
red sea east Africa, Maldives, Philippines
66
00:05:54,490 --> 00:05:57,244
we seeing this kind of problems showing up
67
00:05:57,285 --> 00:05:58,912
in unprecedented rate
68
00:05:58,954 --> 00:06:01,332
Richard showed us how coral reefs to die
69
00:06:01,375 --> 00:06:04,560
and the alarming rate all around the world
70
00:06:05,171 --> 00:06:08,450
ocean warming is the major cause
71
00:06:09,642 --> 00:06:11,889
Richard urged just document coral reefs
72
00:06:11,930 --> 00:06:13,223
on film for science
73
00:06:13,266 --> 00:06:15,379
before they disappear
74
00:06:16,603 --> 00:06:19,816
we knew the Max camera with a credible clarity
75
00:06:19,858 --> 00:06:22,317
was the best way to do this
76
00:06:25,032 --> 00:06:27,383
our mission was clear
77
00:06:28,412 --> 00:06:31,416
bring back images of inside
78
00:06:31,458 --> 00:06:34,400
and why Russy's reef was dying
79
00:06:35,046 --> 00:06:36,799
we need to compare Russy's reef
80
00:06:36,840 --> 00:06:39,844
to other reefs all across the south Pacific
81
00:06:39,886 --> 00:06:42,473
starting with the largest of them all
82
00:06:42,514 --> 00:06:44,513
the Great Barrier Reef
83
00:07:04,169 --> 00:07:06,006
the prospect of diving coral reef
84
00:07:06,047 --> 00:07:08,134
all across the south Pacific
85
00:07:08,175 --> 00:07:11,358
was a bit like a dream come true
86
00:07:12,098 --> 00:07:14,226
we will make hundreds of dives
87
00:07:14,267 --> 00:07:16,812
and some of these would be deeper and more dangerous
88
00:07:16,854 --> 00:07:19,000
than anything we have done before
89
00:07:19,190 --> 00:07:21,611
it would be a most important expedition
90
00:07:21,652 --> 00:07:24,156
in our thirty years' diving together
91
00:07:29,413 --> 00:07:31,291
parts of the Great Barrier Reef
92
00:07:31,332 --> 00:07:35,350
had been protected from overfishing for two decades
93
00:07:35,463 --> 00:07:38,091
the first goal of this ten-month expedition
94
00:07:38,134 --> 00:07:42,250
is to see how well that protection really worked
95
00:07:57,744 --> 00:07:59,956
when I first dove here 22 years ago
96
00:07:59,997 --> 00:08:02,084
these giant clams were not here
97
00:08:02,125 --> 00:08:05,764
they had been fished up by commercial fishmen
98
00:08:06,506 --> 00:08:09,385
today we have seen 12 giant clams
99
00:08:09,428 --> 00:08:10,512
that's a great sign
100
00:08:10,554 --> 00:08:13,651
that means this reef spells its back
101
00:08:16,562 --> 00:08:19,441
a local marine biologist named Tracy Medway
102
00:08:19,483 --> 00:08:22,578
let us to the giant potatocut
103
00:08:23,739 --> 00:08:25,100
they were called potatocut
104
00:08:25,420 --> 00:08:27,077
because they had these patchy potato shape
105
00:08:27,118 --> 00:08:30,066
marking on the sides
106
00:08:33,669 --> 00:08:35,255
throughout most of the Pacific
107
00:08:35,296 --> 00:08:38,425
the really large fish had been wiped out by fishmen
108
00:08:38,468 --> 00:08:43,122
for life here under because of the laws that protect them
109
00:08:50,485 --> 00:08:53,697
this vegetarian protect the reef
110
00:08:53,739 --> 00:08:58,162
neighboring a wave seaweeds that smudged the coral
111
00:08:58,203 --> 00:09:00,874
if too many of this kind of fish are removed
112
00:09:00,915 --> 00:09:03,440
corals will die
113
00:09:03,669 --> 00:09:07,148
that's why overfishing destroy reefs
114
00:09:07,800 --> 00:09:09,427
we often realized
115
00:09:09,468 --> 00:09:11,555
how each species benefits each other
116
00:09:11,596 --> 00:09:14,701
until one of them disappeared
117
00:09:16,646 --> 00:09:18,899
just as the fish protect the reef
118
00:09:18,940 --> 00:09:22,779
the coral offers homes and hiding place for the fish
119
00:09:22,821 --> 00:09:24,990
anything from a simple shark
120
00:09:25,033 --> 00:09:27,870
to a custom dream home
121
00:09:45,393 --> 00:09:49,107
gobies often share a home with shrimp
122
00:09:49,149 --> 00:09:51,611
whenever he ventures out of the burrow
123
00:09:51,695 --> 00:09:55,783
the shrimp keeps at least one antenna on the goby
124
00:09:55,825 --> 00:09:58,204
the goby get a unpackable burrow to live in
125
00:09:58,245 --> 00:10:00,539
without lifting a fin
126
00:10:00,623 --> 00:10:04,504
and the very near sited shrimp gets a bodyguard
127
00:10:04,545 --> 00:10:06,047
with flicked its tale
128
00:10:06,090 --> 00:10:11,011
the goby warns the shrimp of approaching foes
129
00:10:43,182 --> 00:10:44,434
this hundred year old coral
130
00:10:44,476 --> 00:10:45,811
makes a nice dinner's office
131
00:10:45,852 --> 00:10:49,024
for potatocut
132
00:10:49,066 --> 00:10:51,068
a small fish
133
00:10:51,110 --> 00:10:52,070
a clean arrester
134
00:10:52,111 --> 00:10:54,156
swims right into the coral's mouth
135
00:10:54,198 --> 00:10:57,955
to feed and parasites
136
00:11:00,873 --> 00:11:03,502
the coral's gets grunt
137
00:11:03,545 --> 00:11:06,506
and arrester gets dinner
138
00:11:06,549 --> 00:11:11,055
partnerships like this seem to require mutual trust
139
00:11:11,096 --> 00:11:13,851
lots of trust
140
00:11:15,644 --> 00:11:18,106
Cart Hollerway, a coral researcher
141
00:11:18,147 --> 00:11:23,771
joined Michael to study interest species communication
142
00:11:56,034 --> 00:11:57,452
I was afraid I was going to heaven
143
00:11:57,495 --> 00:11:59,038
maybe swollen with
144
00:11:59,079 --> 00:12:00,248
but I didn't
145
00:12:00,290 --> 00:12:03,733
it just chin and a little bit
146
00:12:06,590 --> 00:12:09,870
I was studying animal behavior for so many years
147
00:12:09,803 --> 00:12:10,888
this was
148
00:12:10,929 --> 00:12:11,806
this was different
149
00:12:11,847 --> 00:12:13,266
this was a chance for meet it
150
00:12:13,308 --> 00:12:16,242
actually be part of it
151
00:12:18,399 --> 00:12:22,571
cooperation between species sustained lives here
152
00:12:22,612 --> 00:12:26,326
but sometimes it is almost invisible
153
00:12:26,367 --> 00:12:28,913
the coral's most important partners
154
00:12:28,955 --> 00:12:31,333
are tiny microscope alga
155
00:12:31,417 --> 00:12:36,146
that actually live inside the coral and most tissues
156
00:12:37,382 --> 00:12:40,680
this help alga use sunlight to produce sugar
157
00:12:40,721 --> 00:12:42,098
the primary food source
158
00:12:42,139 --> 00:12:46,229
that give coral the energy to build reefs
159
00:12:46,270 --> 00:12:50,275
most corals cannot survive without helper alga
160
00:12:50,318 --> 00:12:51,652
but worldwide
161
00:12:51,695 --> 00:12:53,655
abnormally warm seawater
162
00:12:53,698 --> 00:12:56,647
threaten this partnership
163
00:12:57,578 --> 00:12:59,622
time-up photography can show us how
164
00:12:59,663 --> 00:13:01,249
and just one week
165
00:13:01,291 --> 00:13:06,394
that changed two centigrade drives the alga out
166
00:13:08,009 --> 00:13:10,012
without its main food source
167
00:13:10,053 --> 00:13:13,707
the coral bleaches as ghostly white
168
00:13:15,519 --> 00:13:17,313
if the alga don't return
169
00:13:17,356 --> 00:13:19,670
the corals starves
170
00:13:24,407 --> 00:13:26,535
here in Australia we went to some places that
171
00:13:26,576 --> 00:13:28,453
we have been to 22 years before
172
00:13:28,496 --> 00:13:29,914
and we are surprise to see that
173
00:13:29,956 --> 00:13:35,000
some of the reefs so damaged by ocean warming
174
00:13:38,927 --> 00:13:41,555
part Australian survey give us a baseline
175
00:13:41,597 --> 00:13:44,018
for understanding what was going wrong
176
00:13:44,059 --> 00:13:45,019
at Russy's reefs
177
00:13:45,060 --> 00:13:48,792
2000 miles away in Fiji
178
00:14:28,412 --> 00:14:29,706
when we got to Fuji
179
00:14:29,747 --> 00:14:34,296
it didn't take five minutes to reconnect with Russy
180
00:14:36,966 --> 00:14:40,801
Howard makes me smile again
181
00:14:42,140 --> 00:14:44,518
Micheal and I were eager to help Russy
182
00:14:44,559 --> 00:14:45,519
but first
183
00:14:45,561 --> 00:14:49,542
we have to pay our respect to local tradition
184
00:14:53,280 --> 00:14:56,535
before outsiders can direct my home island
185
00:14:56,576 --> 00:15:00,560
the elders must grant permission
186
00:15:02,502 --> 00:15:06,410
my people have always limited fishing
187
00:15:06,715 --> 00:15:08,802
this tradition of reef conservation
188
00:15:08,843 --> 00:15:11,096
has worked well for centuries
189
00:15:11,139 --> 00:15:13,724
till now
190
00:15:15,352 --> 00:15:18,065
first I wanted Howard to see village reef
191
00:15:18,106 --> 00:15:20,708
as it used to be
192
00:15:32,376 --> 00:15:35,255
the reef looks great with plenty of small fish
193
00:15:35,297 --> 00:15:38,468
but we didn't see many big fish
194
00:15:38,684 --> 00:15:40,207
as we did in Australia
195
00:15:40,907 --> 00:15:42,792
and that worried me
196
00:15:46,145 --> 00:15:48,732
but time had come
197
00:15:48,774 --> 00:15:52,746
I took Howard and Michael further down the reef
198
00:15:58,162 --> 00:16:00,950
I wonder where all the animals gone
199
00:16:04,838 --> 00:16:07,874
these reefs are dying
200
00:16:08,468 --> 00:16:12,020
and all just makes me very sad
201
00:16:16,918 --> 00:16:19,811
seeing so much of these reef destroyed
202
00:16:20,380 --> 00:16:21,626
we realized that
203
00:16:20,861 --> 00:16:25,277
Russy's reef may be what all coral reefs look like
204
00:16:25,681 --> 00:16:27,210
in thirty years
205
00:16:30,290 --> 00:16:34,045
our reef was to be home of so many creatures
206
00:16:34,086 --> 00:16:38,271
but now they almost all gone
207
00:16:44,146 --> 00:16:45,982
after seen all these destruction though
208
00:16:46,239 --> 00:16:48,243
I saw an octopus
209
00:16:52,768 --> 00:16:54,901
octopus is made like a tent with the body
210
00:16:54,920 --> 00:16:56,820
they put up their eight arms and
211
00:16:57,150 --> 00:17:01,181
actually traps shrimps and crabs live on the reef
212
00:17:07,175 --> 00:17:09,178
here octopus figure out
213
00:17:09,219 --> 00:17:12,020
how to survive
214
00:17:12,683 --> 00:17:17,312
not many reef to do that
215
00:17:22,822 --> 00:17:25,241
for islander survive by fishing
216
00:17:25,283 --> 00:17:28,455
the death of the reef is really hit us hard
217
00:17:28,496 --> 00:17:32,371
especially when you have children to feed
218
00:17:38,844 --> 00:17:41,680
but what kills Russy's reef?
219
00:17:41,764 --> 00:17:46,187
Foreign fishing fleets have overfished this water
220
00:17:46,229 --> 00:17:51,543
and thermometer tells us that
the ocean is two degrees warmer than normal
221
00:17:54,111 --> 00:17:56,994
I found more bleached coral and no big fish
222
00:17:57,036 --> 00:17:59,455
but I had a hunch that
223
00:17:59,498 --> 00:18:01,239
ocean warming and overfishing
224
00:18:01,331 --> 00:18:03,731
were not the only problems
225
00:18:10,721 --> 00:18:12,391
ten mile inland
226
00:18:12,432 --> 00:18:15,953
when tropical rain forest were cut down
227
00:18:16,000 --> 00:18:19,012
the river turn muddy with silt
228
00:18:26,786 --> 00:18:28,788
two rivers merged
229
00:18:28,830 --> 00:18:31,320
one with logging upstream
230
00:18:31,330 --> 00:18:34,087
one without
231
00:18:35,234 --> 00:18:40,346
there was only place for all that settlement to go
232
00:18:42,296 --> 00:18:43,512
at the mouth of the river
233
00:18:43,581 --> 00:18:46,237
silt block the sun light that the coral needs to growth
234
00:18:48,398 --> 00:18:53,421
Russy's reef had been hit
by a combination of stresses
235
00:18:54,948 --> 00:18:58,997
ocean warming overfishing and siltation
236
00:19:00,059 --> 00:19:01,842
corals may fight off one threat
237
00:19:00,916 --> 00:19:05,590
but three at once proved too much
238
00:19:06,698 --> 00:19:09,025
now I understand the problem better
239
00:19:07,968 --> 00:19:10,053
but what could I do
240
00:19:10,096 --> 00:19:12,815
Howard thought a healthier reef
241
00:19:11,764 --> 00:19:14,792
might give us some answers
242
00:19:14,184 --> 00:19:17,696
we set quest to another island
243
00:19:18,440 --> 00:19:21,937
there we joined up with John Michealgusto
244
00:19:21,236 --> 00:19:25,158
who is the son of the legendary explorer
245
00:19:26,284 --> 00:19:30,082
John Michealgusto comes to Fuji every year
to help marine biologists
246
00:19:29,247 --> 00:19:32,114
like marine's world read records
247
00:19:35,653 --> 00:19:38,553
we guild Howard and Michael to a nearby reef
248
00:19:38,823 --> 00:19:40,935
where siltation is not a problem
249
00:19:41,202 --> 00:19:43,550
thanks to mangrove trees
250
00:19:45,634 --> 00:19:47,412
their roots traps the silt
251
00:19:47,858 --> 00:19:49,675
protecting the reefs
252
00:19:53,089 --> 00:19:57,000
many fish sees mangroves as nursery
to protect the young
253
00:20:03,211 --> 00:20:04,847
my fellow Fijians
254
00:20:04,337 --> 00:20:08,034
have set aside this beneficial as mangroves
255
00:20:08,198 --> 00:20:10,254
as part of marine preserve
256
00:20:10,921 --> 00:20:13,449
making the reef offshore a wonder land
257
00:20:13,829 --> 00:20:16,650
healthy beautiful and strong
258
00:20:21,602 --> 00:20:24,350
this is the way I want my reef to be
259
00:20:28,782 --> 00:20:32,652
tropical coral reefs are found worldwide
260
00:20:33,182 --> 00:20:37,667
Fuji is the soft coral capital of the world
261
00:21:20,993 --> 00:21:22,662
corals are beautiful
262
00:21:22,704 --> 00:21:25,420
but they are also beneficial
263
00:21:25,624 --> 00:21:27,668
chemical components from coral reefs
264
00:21:27,711 --> 00:21:29,421
have been reproduced in the lab
265
00:21:29,463 --> 00:21:31,842
to provide relief from pain
266
00:21:32,465 --> 00:21:33,385
ease child birth
267
00:21:33,426 --> 00:21:37,156
and even extend the life of AIDS patients
268
00:21:38,809 --> 00:21:41,210
corals share their foods
269
00:21:41,396 --> 00:21:44,921
in fact many of them share the same stomach
270
00:22:04,428 --> 00:22:06,431
when the current fix up speed
271
00:22:06,472 --> 00:22:08,100
time lap photographs shows
272
00:22:08,142 --> 00:22:11,730
how these soft corals inflate like balloons
273
00:22:11,772 --> 00:22:14,000
to trap passing animals
274
00:22:19,616 --> 00:22:22,037
on a healthy reef like this
275
00:22:22,078 --> 00:22:25,618
you see so many different creatures
276
00:22:30,840 --> 00:22:33,469
we preferred not to approach these animals
277
00:22:33,510 --> 00:22:36,218
it's better of they come to us
278
00:22:38,016 --> 00:22:39,727
this distant cousin of the cobra
279
00:22:39,769 --> 00:22:43,357
can kill a person in a matter of minutes
280
00:22:43,399 --> 00:22:46,201
but they rarely bite humans
281
00:22:46,612 --> 00:22:49,055
Michael is counting on that
282
00:22:56,125 --> 00:22:58,713
we learned a lot of our reef from its animals
283
00:22:58,754 --> 00:23:01,048
and so do the children
284
00:23:01,091 --> 00:23:04,552
there is more to the reef than meets the eyes
285
00:23:29,338 --> 00:23:33,600
observation is the first step in science
286
00:23:36,640 --> 00:23:38,309
who would notice
287
00:23:38,350 --> 00:23:41,438
that yellow fish got their tiny eggs
288
00:23:41,479 --> 00:23:43,911
before they hatch
289
00:23:44,693 --> 00:23:47,363
all that the sea cucumber eat the waste
290
00:23:47,405 --> 00:23:50,934
leaving the reef clean up for all
291
00:23:54,456 --> 00:23:59,129
some of the finest marine biologists are Fijians
292
00:23:59,172 --> 00:24:02,986
we could expect scientists mixed
293
00:24:29,380 --> 00:24:32,008
we've learned that we don't inherit the earth
294
00:24:32,050 --> 00:24:33,761
from our parents
295
00:24:33,802 --> 00:24:37,106
we borrow it from our children
296
00:24:39,018 --> 00:24:43,149
children love this spot fish they've never seen before
297
00:24:43,190 --> 00:24:46,820
that same discovery drives many scientist
298
00:24:46,904 --> 00:24:49,170
like Richard Pile
299
00:24:52,829 --> 00:24:56,292
Richard Pile calls himself a fishman
300
00:24:56,334 --> 00:25:00,734
he study fish on the deepest parts of coral reefs
301
00:25:02,050 --> 00:25:03,386
the deeper down we go on the coral reef
302
00:25:03,427 --> 00:25:05,471
the less we know
303
00:25:05,514 --> 00:25:07,911
I want to find out who lives there
304
00:25:09,686 --> 00:25:11,814
you can't get a true picture of coral reef
305
00:25:11,855 --> 00:25:14,192
if you only look at part of it
306
00:25:14,233 --> 00:25:16,862
but deep dives could be really dangerous
307
00:25:16,905 --> 00:25:19,199
even using a special breathing devises
308
00:25:19,240 --> 00:25:21,703
we could still get a fatal disease
309
00:25:21,744 --> 00:25:23,456
called "the bangs"
310
00:25:26,919 --> 00:25:28,671
we nearly lost Howard on a deep dive
311
00:25:28,712 --> 00:25:30,965
only two months ago
312
00:25:31,007 --> 00:25:33,928
ha had a bad case of "the bangs"
313
00:25:33,970 --> 00:25:37,349
it could have killed him
314
00:25:37,391 --> 00:25:39,644
to stop the progression of the illness
315
00:25:39,686 --> 00:25:41,856
I began breathing pure oxygen
316
00:25:41,897 --> 00:25:43,733
but it didn't seen to help
317
00:25:43,774 --> 00:25:47,739
I was losing all the feelings in my right legs
318
00:25:47,780 --> 00:25:49,992
one of the terrify moment for me
319
00:25:50,033 --> 00:25:53,872
was actually seeing him stumble
320
00:25:53,914 --> 00:25:57,461
I just thought it can't be happening
321
00:25:57,502 --> 00:26:00,047
Michael rushed Howard to the hospital
322
00:26:00,090 --> 00:26:02,718
hoping the specially pressurized chamber
323
00:26:02,760 --> 00:26:04,888
might hold the illness
324
00:26:04,929 --> 00:26:08,383
and save his life
325
00:26:09,644 --> 00:26:11,313
thank god for the communication system
326
00:26:11,355 --> 00:26:14,414
because at least then I could talk to him
327
00:26:18,615 --> 00:26:20,826
Howard survived
328
00:26:20,869 --> 00:26:22,746
but his closest call was on my mind that
329
00:26:22,787 --> 00:26:27,251
we prepare for the dive to the 350 feet
330
00:26:28,671 --> 00:26:31,215
the next day on the deep dive
331
00:26:31,258 --> 00:26:33,302
Howard and Richard would face pressures
332
00:26:33,343 --> 00:26:36,557
nearly 12 times greater than the normal
333
00:26:36,598 --> 00:26:39,144
but they are expert divers
334
00:26:39,185 --> 00:26:41,730
and there is much to learn by exploring regions
335
00:26:41,773 --> 00:26:44,198
where so little was known
336
00:26:59,172 --> 00:27:02,384
support divers attached safety tanks to a life line
337
00:27:02,426 --> 00:27:07,612
every 50 feet
338
00:27:36,265 --> 00:27:37,933
as we descent
339
00:27:37,976 --> 00:27:40,646
too much oxygen is bad
340
00:27:40,687 --> 00:27:42,857
too little is worse
341
00:27:42,899 --> 00:27:45,390
both can kill you
342
00:27:52,120 --> 00:27:56,886
the safety divers go down as far as he can and stop
343
00:27:57,252 --> 00:27:58,420
after that
344
00:27:58,462 --> 00:28:00,975
we are on our own
345
00:28:06,473 --> 00:28:08,059
as we drop down the reef wall
346
00:28:08,100 --> 00:28:11,104
it gets darker and colder
347
00:28:11,147 --> 00:28:15,403
and in a way we are going back in time
348
00:28:15,444 --> 00:28:16,905
at 200 feet
349
00:28:16,946 --> 00:28:20,034
we pass lime stone deposited the lay down
350
00:28:20,075 --> 00:28:22,287
twenty thousand years ago
351
00:28:22,329 --> 00:28:25,616
back when this was the top of the reef
352
00:28:33,135 --> 00:28:34,805
at 350 feet
353
00:28:34,846 --> 00:28:37,883
we entered the twilight zones
354
00:28:39,477 --> 00:28:41,689
it's sort of spooky but wonderful
355
00:28:41,731 --> 00:28:43,233
to look around the reef that
356
00:28:43,317 --> 00:28:46,930
no one has ever lay eyes on for
357
00:28:58,754 --> 00:29:02,224
it's starting to get interesting
358
00:29:06,181 --> 00:29:12,398
it's that we could see fan corals and weed corals
359
00:29:13,149 --> 00:29:17,044
this community definitely appeared to be thriving
360
00:29:18,115 --> 00:29:20,744
in his quest to find out what lives down here
361
00:29:20,785 --> 00:29:24,456
Richard can only bring a few back to the surface
362
00:29:24,499 --> 00:29:27,710
to be documented for science
363
00:29:30,924 --> 00:29:33,678
looking around I see at least a dozen of new species
364
00:29:33,719 --> 00:29:35,722
I have never seen before
365
00:29:35,764 --> 00:29:38,886
I doubt that anyone has seen them before
366
00:29:45,444 --> 00:29:46,946
scientists like Richard
367
00:29:46,988 --> 00:29:48,865
are mapping the web of life that
368
00:29:48,908 --> 00:29:51,036
we are all part of
369
00:29:51,077 --> 00:29:53,497
each new fish Richard finds
370
00:29:53,539 --> 00:29:56,501
told millions of years of genetic engineering
371
00:29:56,953 --> 00:29:59,560
for medical research
372
00:30:10,222 --> 00:30:12,057
then the intense water pressure
373
00:30:12,099 --> 00:30:13,934
caused the primary camera
374
00:30:13,977 --> 00:30:16,014
to no function
375
00:30:17,983 --> 00:30:21,349
I was glad that Howard coordinate into the dive
376
00:30:22,864 --> 00:30:24,408
we hope that Howard's images
377
00:30:24,449 --> 00:30:26,452
would let scientist explore reefs
378
00:30:26,494 --> 00:30:29,893
that they might never be able to dive on the rope
379
00:30:31,417 --> 00:30:33,379
it's not everyday you can witness
380
00:30:33,420 --> 00:30:36,500
that a discovery of a new species of fish
381
00:30:36,591 --> 00:30:38,343
you see the red one with the long tale
382
00:30:38,386 --> 00:30:39,387
that's what I was really excited
383
00:30:39,429 --> 00:30:41,598
that's definitely live
384
00:30:41,640 --> 00:30:44,993
oh I see those all the time
385
00:31:10,972 --> 00:31:12,308
until quite recently
386
00:31:12,349 --> 00:31:14,977
the deep coral reef was
387
00:31:14,890 --> 00:31:18,033
the big dark boy on the map of life
388
00:31:18,358 --> 00:31:19,735
but each new discovery
389
00:31:19,776 --> 00:31:22,300
leads us to the new connection
390
00:31:23,574 --> 00:31:26,285
this may seen like just some magnificent red fish
391
00:31:26,328 --> 00:31:28,037
but it's very important piece
392
00:31:28,080 --> 00:31:29,915
to the biodiversity puzzle
393
00:31:29,958 --> 00:31:32,377
as soon as I saw I knew it's something different
394
00:31:32,418 --> 00:31:36,150
the months of hard work in Fiji paid off
395
00:31:38,051 --> 00:31:39,846
Russy have seen first time
396
00:31:39,888 --> 00:31:43,518
how corals can thrive when reefs are protected
397
00:31:43,559 --> 00:31:47,377
he is now ready to return to his home island
398
00:31:49,067 --> 00:31:50,819
my fellow Fijians have shown me
399
00:31:50,862 --> 00:31:53,115
how to set up a marine preserve
400
00:31:53,156 --> 00:31:54,783
protect the mangroves
401
00:31:54,825 --> 00:31:58,037
and even cut logging operations
402
00:31:58,288 --> 00:32:01,200
I really want to get started
403
00:32:02,794 --> 00:32:05,464
here in Fiji we have seen some amazing reefs
404
00:32:05,507 --> 00:32:08,719
but we have also seen a lot of coral damages
405
00:32:08,803 --> 00:32:11,181
the siltation we saw in Russy's reef
406
00:32:11,222 --> 00:32:13,917
let us to a next question
407
00:32:14,019 --> 00:32:15,478
is closeness to shore
408
00:32:15,521 --> 00:32:18,743
a major risk factor for corals?
409
00:32:22,071 --> 00:32:23,782
French Polynesia is a perfect place
410
00:32:23,824 --> 00:32:27,259
for answering this question
411
00:32:47,398 --> 00:32:48,858
in French Polynesia
412
00:32:48,900 --> 00:32:50,652
Howard and Michael started with
413
00:32:50,695 --> 00:32:54,074
the heavily populated islands of Tahiti and Maria
414
00:32:54,116 --> 00:32:58,014
where the reefs are close to shore
415
00:32:58,163 --> 00:33:01,000
but with only six weeks left in the whole expedition
416
00:33:01,042 --> 00:33:04,894
Howard had to get the big picture fast
417
00:33:17,565 --> 00:33:18,942
I’m used to hang gliders
418
00:33:19,025 --> 00:33:22,364
I’m used to fly around like this
419
00:33:22,446 --> 00:33:24,742
but there is still something not quite right
420
00:33:24,783 --> 00:33:27,846
about the engine that was fit in my back pack
421
00:33:36,841 --> 00:33:40,096
Maria is sort of like Russy's island
422
00:33:40,139 --> 00:33:41,891
the coral here is very sensitive
423
00:33:41,932 --> 00:33:43,769
to siltation and pollution
424
00:33:43,810 --> 00:33:47,605
because the corals are great close to the shore
425
00:33:48,275 --> 00:33:51,571
after checking out the north side of Maria
426
00:33:51,612 --> 00:33:55,448
we crossed the mountain to survey the south coast
427
00:34:32,712 --> 00:34:34,255
even near towns
428
00:34:34,296 --> 00:34:37,500
we didn't spot much reef damages
429
00:34:37,760 --> 00:34:40,889
coastal development put reef in jeopardy
430
00:34:40,931 --> 00:34:44,269
siltation pollution and the lose of mangroves
431
00:34:44,310 --> 00:34:46,856
are all serious risks
432
00:34:46,898 --> 00:34:48,734
but resource like this proved that
433
00:34:48,775 --> 00:34:51,654
respecting the environment is a good business
434
00:34:51,695 --> 00:34:56,780
because tourists avoided damaged reefs
435
00:35:06,090 --> 00:35:07,551
our flight over Maria
436
00:35:07,593 --> 00:35:09,554
just gave us a first impression
437
00:35:09,595 --> 00:35:11,140
so was time running out
438
00:35:11,181 --> 00:35:13,726
I turned to recheck board survey boat
439
00:35:13,769 --> 00:35:16,063
the Quicksilver Crossing
440
00:35:16,104 --> 00:35:20,528
reef check has over 4000 sport divers in 60 countries
441
00:35:20,569 --> 00:35:24,441
the health of coral reef
442
00:35:24,741 --> 00:35:26,369
we ask three check voluntaries
443
00:35:26,411 --> 00:35:28,164
to check the coral damage here in Maria
444
00:35:28,205 --> 00:35:30,750
to find out if the reefs close to shore
445
00:35:30,792 --> 00:35:33,700
are the most severely damaged
446
00:35:45,771 --> 00:35:46,772
from the air
447
00:35:46,815 --> 00:35:49,819
it's clear how these volcano islands formed
448
00:35:49,860 --> 00:35:54,120
and how coral reefs formed around them
449
00:35:57,120 --> 00:36:00,208
the steepest youngest islands Tahiti and Maria
450
00:36:00,250 --> 00:36:02,336
stands tall
451
00:36:02,377 --> 00:36:05,757
these islands have not eroded and subsided much
452
00:36:05,841 --> 00:36:10,209
so the coral reefs ringing them is not far offshore
453
00:36:17,815 --> 00:36:21,070
the volcano has subsided and eroded somewhat
454
00:36:21,112 --> 00:36:24,995
and the reefs are farther from shore
455
00:36:27,078 --> 00:36:28,289
the final stage
456
00:36:28,330 --> 00:36:32,795
is this flat and the island called and atop
457
00:36:32,836 --> 00:36:36,550
the volcano has completely subsided back into the sea
458
00:36:36,591 --> 00:36:42,145
leaving a ring coral which one circled a top mountain
459
00:36:45,062 --> 00:36:48,942
the team headed for the second largest in the world
460
00:36:48,984 --> 00:36:50,569
Rangeroa
461
00:36:50,611 --> 00:36:55,151
to survey the remotest reef in French Polynesia
462
00:36:57,579 --> 00:36:59,498
10 years ago
463
00:36:59,541 --> 00:37:02,795
a cyclone wiped out most Rangeroa's coral
464
00:37:02,837 --> 00:37:04,505
but storms are natural events
465
00:37:04,548 --> 00:37:07,176
and coral reef still recovered from them
466
00:37:07,218 --> 00:37:11,119
as long as human impacts don't interfere
467
00:37:12,308 --> 00:37:16,605
here the coral seems small but healthy
468
00:37:20,069 --> 00:37:22,280
right away we saw two male fish
469
00:37:22,322 --> 00:37:25,616
fighting over territory
470
00:37:26,285 --> 00:37:31,605
this was a sign of large thriving fish population
471
00:37:34,881 --> 00:37:37,176
but why haven't we seen the huge sharks
472
00:37:37,218 --> 00:37:41,796
in great reef shores Rangeroa so famous for
473
00:37:43,017 --> 00:37:46,731
their absence is not necessarily a danger sign for corals
474
00:37:46,773 --> 00:37:50,653
but it could single and balance the whole reef eco system
475
00:37:50,694 --> 00:37:54,867
so finding the shark became our main goal
476
00:37:56,787 --> 00:37:59,290
we search the shark's favorite hangouts
477
00:37:59,331 --> 00:38:02,377
but they didn't see to be home
478
00:38:08,469 --> 00:38:09,679
we use caution because
479
00:38:09,721 --> 00:38:11,307
one thing you don't want to do
480
00:38:11,348 --> 00:38:15,603
is catch a great reef shark by surprise
481
00:38:19,527 --> 00:38:22,238
if the shark louse around the water
482
00:38:22,281 --> 00:38:23,865
the quickest way to spot them
483
00:38:23,908 --> 00:38:26,354
is from the outer light
484
00:38:27,120 --> 00:38:28,246
throughout the Pacific
485
00:38:28,330 --> 00:38:30,750
whole population of sharks had been wiped out
486
00:38:30,793 --> 00:38:32,920
by commercial fishermen
487
00:38:32,962 --> 00:38:35,632
great reef shark are especially vulnerable
488
00:38:35,674 --> 00:38:38,567
and that's what worry me
489
00:38:39,387 --> 00:38:42,350
the airy search for sharks turns out nothing
490
00:38:42,391 --> 00:38:44,144
and we are running out of time
491
00:38:44,186 --> 00:38:46,397
but there is one last place to look
492
00:38:46,439 --> 00:38:48,609
to Puta Pass
493
00:38:48,650 --> 00:38:52,054
here the current just screams
494
00:39:28,164 --> 00:39:30,626
hundreds of starve sharks are hang out
495
00:39:30,667 --> 00:39:33,337
like street gang in the canyon
496
00:39:33,380 --> 00:39:35,132
we were being swept into them
497
00:39:35,173 --> 00:39:40,522
and there is nothing we can do about it
498
00:39:59,707 --> 00:40:02,712
could they be mating
499
00:40:02,753 --> 00:40:04,088
this is when you try very hard
500
00:40:04,130 --> 00:40:07,482
not to look like a shark
501
00:40:07,635 --> 00:40:13,198
I have two friends badly bitten by great reef sharks
502
00:40:14,603 --> 00:40:16,397
the most social of all sharks
503
00:40:16,439 --> 00:40:20,855
graze tender swimming tight groups
504
00:40:31,961 --> 00:40:34,005
I’ve been diving for 35 years
505
00:40:34,046 --> 00:40:37,635
but I’ve never seen the life like this
506
00:40:37,676 --> 00:40:40,055
there must be 300 sharks in this school
507
00:40:40,097 --> 00:40:43,304
and that's a healthy number
508
00:40:45,355 --> 00:40:47,774
this big school doesn't close the book
509
00:40:47,815 --> 00:40:50,027
but it is a favorable sign
510
00:40:50,069 --> 00:40:53,849
for the health of this reef ego-system
511
00:40:57,663 --> 00:40:59,957
we party with the sharks for nearly an hour
512
00:41:00,000 --> 00:41:01,710
knowing that on our way home
513
00:41:01,752 --> 00:41:03,171
we have a current on our backs
514
00:41:03,212 --> 00:41:06,987
so we can go with the float
515
00:42:03,921 --> 00:42:07,051
for ten exhausting but magical months
516
00:42:07,093 --> 00:42:08,345
Michael and I explored
517
00:42:08,386 --> 00:42:13,894
some of the most magnificent coral reefs on earth
518
00:42:13,935 --> 00:42:14,854
during that time
519
00:42:14,895 --> 00:42:20,226
our concern for coral grew into a share passion
520
00:42:25,410 --> 00:42:27,246
my people look at the reef
521
00:42:27,288 --> 00:42:29,541
and we don't want to believe such a place
522
00:42:29,582 --> 00:42:32,723
could be gone forever
523
00:42:33,755 --> 00:42:35,715
my friends Howard and Michael
524
00:42:35,758 --> 00:42:41,200
have given me new tools to heal my village reef
525
00:42:41,808 --> 00:42:46,564
Howard's love to the reefs nearly cost his life
526
00:42:46,606 --> 00:42:48,817
but after making more than 500 dives
527
00:42:48,859 --> 00:42:52,614
we came back with some really powerful images
528
00:42:52,657 --> 00:42:54,409
one image I can't get out of my mind
529
00:42:54,450 --> 00:42:58,289
is that alone octopus crawling to the rubble
530
00:42:58,331 --> 00:43:02,444
soon it may not have a home
531
00:43:05,257 --> 00:43:07,885
no one set out to kill a beautiful thing
532
00:43:07,928 --> 00:43:09,596
but when a reef dies
533
00:43:09,638 --> 00:43:14,228
billions of living things die
534
00:43:14,269 --> 00:43:17,107
corals appears to be dying faster than normal
535
00:43:17,148 --> 00:43:21,780
and the trend is rapidly accelerating
536
00:43:22,489 --> 00:43:25,368
most living coral reefs as we know today
537
00:43:25,410 --> 00:43:28,832
could be gone in 30 years
538
00:43:28,873 --> 00:43:30,542
if that happens
539
00:43:30,584 --> 00:43:35,707
then something inside of me will die too
540
00:43:40,806 --> 00:43:43,435
after all the coral reefs have given to us
541
00:43:43,477 --> 00:43:47,023
more and more people are now returning the favor
542
00:43:47,107 --> 00:43:50,028
their supporting leaders who fight global warming
543
00:43:50,069 --> 00:43:52,490
joining teams like "Reef Check"
544
00:43:52,531 --> 00:43:56,317
getting involved
545
00:43:56,996 --> 00:43:58,539
we may have great potential
546
00:43:58,581 --> 00:43:59,750
of finding new medicines on
547
00:43:59,791 --> 00:44:03,713
coral reefs than any other environment on earth
548
00:44:03,755 --> 00:44:08,438
to save them is really saving ourselves
549
00:44:21,487 --> 00:44:23,658
it take a long long time to build a coral reef
550
00:44:23,699 --> 00:44:26,161
step by step
551
00:44:26,203 --> 00:44:28,873
the reef survive on partnerships
552
00:44:28,915 --> 00:44:30,876
and the most important partners
553
00:44:30,918 --> 00:44:36,097
that the corals have are you and I
554
00:44:59,624 --> 00:45:01,627
what we must to do is
555
00:45:01,668 --> 00:45:03,379
encourage a sea change in attitude
556
00:45:03,421 --> 00:45:05,048
one that acknowledges
557
00:45:05,091 --> 00:45:06,593
we are a part of the living world
558
00:45:06,634 --> 00:45:09,891
not apart from it
559
00:45:10,000 --> 00:45:13,116
