I would like to share with you this morning
0
1000
3000
00:19
some stories about the ocean
1
4000
2000
00:21
through my work as a still photographer
2
6000
2000
00:23
for National Geographic magazine.
3
8000
3000
00:26
I guess I became an underwater photographer
4
11000
2000
00:28
and a photojournalist
5
13000
2000
00:30
because I fell in love with the sea as a child.
6
15000
2000
00:32
And I wanted to tell stories
7
17000
2000
00:34
about all the amazing things I was seeing underwater,
8
19000
3000
00:37
incredible wildlife and interesting behaviors.
9
22000
3000
00:40
And after even 30 years of doing this,
10
25000
2000
00:42
after 30 years of exploring the ocean,
11
27000
2000
00:44
I never cease to be amazed
12
29000
2000
00:46
at the extraordinary encounters that I have while I'm at sea.
13
31000
3000
00:49
But more and more frequently these days
14
34000
2000
00:51
I'm seeing terrible things underwater as well,
15
36000
2000
00:53
things that I don't think most people realize.
16
38000
3000
00:56
And I've been compelled to turn my camera towards these issues
17
41000
3000
00:59
to tell a more complete story.
18
44000
2000
01:01
I want people to see what's happening underwater,
19
46000
2000
01:03
both the horror and the magic.
20
48000
3000
01:06
The first story that I did for National Geographic,
21
51000
2000
01:08
where I recognized the ability to include
22
53000
2000
01:10
environmental issues within a natural history coverage,
23
55000
3000
01:13
was a story I proposed on harp seals.
24
58000
3000
01:16
The story I wanted to do initially
25
61000
2000
01:18
was just a small focus to look at the few weeks each year
26
63000
3000
01:21
where these animals migrate down from the Canadian arctic
27
66000
3000
01:24
to the Gulf of St. Lawrence in Canada
28
69000
2000
01:26
to engage in courtship, mating and to have their pups.
29
71000
3000
01:29
And all of this is played out against
30
74000
2000
01:31
the backdrop of transient pack ice
31
76000
2000
01:33
that moves with wind and tide.
32
78000
2000
01:35
And because I'm an underwater photographer,
33
80000
2000
01:37
I wanted to do this story from both above and below,
34
82000
2000
01:39
to make pictures like this that show one of these little pups
35
84000
3000
01:42
making its very first swim in the icy 29-degree water.
36
87000
3000
01:45
But as I got more involved in the story,
37
90000
2000
01:47
I realized that there were two big environmental issues I couldn't ignore.
38
92000
3000
01:50
The first was that these animals continue to be hunted,
39
95000
3000
01:53
killed with hakapiks at about eight, 15 days old.
40
98000
3000
01:56
It actually is the largest marine mammal
41
101000
2000
01:58
slaughter on the planet,
42
103000
2000
02:00
with hundreds of thousands of these seals being killed every year.
43
105000
3000
02:03
But as disturbing as that is,
44
108000
2000
02:05
I think the bigger problem for harp seals
45
110000
2000
02:07
is the loss of sea ice due to global warming.
46
112000
2000
02:09
This is an aerial picture that I made that shows
47
114000
2000
02:11
the Gulf of St. Lawrence during harp seal season.
48
116000
3000
02:14
And even though we see a lot of ice in this picture,
49
119000
2000
02:16
there's a lot of water as well, which wasn't there historically.
50
121000
3000
02:19
And the ice that is there is quite thin.
51
124000
3000
02:22
The problem is that these pups need a stable platform of solid ice
52
127000
3000
02:25
in order to nurse from their moms.
53
130000
2000
02:27
They only need 12 days from the moment they're born until they're on their own.
54
132000
3000
02:30
But if they don't get 12 days,
55
135000
2000
02:32
they can fall into the ocean and die.
56
137000
2000
02:34
This is a photo that I made showing
57
139000
2000
02:36
one of these pups that's only about five or seven days old --
58
141000
2000
02:38
still has a little bit of the umbilical cord on its belly --
59
143000
2000
02:40
that has fallen in because of the thin ice,
60
145000
2000
02:42
and the mother is frantically trying to push it up to breathe
61
147000
3000
02:45
and to get it back to stable purchase.
62
150000
2000
02:47
This problem has continued to grow each year since I was there.
63
152000
3000
02:50
I read that last year the pup mortality rate
64
155000
2000
02:52
was 100 percent in parts of the Gulf of St. Lawrence.
65
157000
3000
02:55
So, clearly, this species has a lot of problems going forward.
66
160000
3000
02:58
This ended up becoming a cover story at National Geographic.
67
163000
3000
03:01
And it received quite a bit of attention.
68
166000
2000
03:03
And with that, I saw the potential to begin
69
168000
2000
03:05
doing other stories about ocean problems.
70
170000
2000
03:07
So I proposed a story on the global fish crisis,
71
172000
3000
03:10
in part because I had personally witnessed
72
175000
3000
03:13
a lot of degradation in the ocean over the last 30 years,
73
178000
2000
03:15
but also because I read a scientific paper
74
180000
2000
03:17
that stated that 90 percent of the big fish in the ocean
75
182000
3000
03:20
have disappeared in the last 50 or 60 years.
76
185000
2000
03:22
These are the tuna, the billfish and the sharks.
77
187000
3000
03:25
When I read that, I was blown away by those numbers.
78
190000
2000
03:27
I thought this was going to be headline news in every media outlet,
79
192000
3000
03:30
but it really wasn't, so I wanted to do a story
80
195000
3000
03:33
that was a very different kind of underwater story.
81
198000
3000
03:36
I wanted it to be more like war photography,
82
201000
2000
03:38
where I was making harder-hitting pictures
83
203000
2000
03:40
that showed readers what was happening
84
205000
2000
03:42
to marine wildlife around the planet.
85
207000
2000
03:44
The first component of the story that I thought was essential, however,
86
209000
3000
03:47
was to give readers a sense of appreciation
87
212000
3000
03:50
for the ocean animals that they were eating.
88
215000
2000
03:52
You know, I think people go into a restaurant,
89
217000
2000
03:54
and somebody orders a steak, and we all know where steak comes from,
90
219000
3000
03:57
and somebody orders a chicken, and we know what a chicken is,
91
222000
3000
04:00
but when they're eating bluefin sushi,
92
225000
2000
04:02
do they have any sense of the magnificent animal that they're consuming?
93
227000
3000
04:05
These are the lions and tigers of the sea.
94
230000
3000
04:08
In reality, these animals have no terrestrial counterpart;
95
233000
2000
04:10
they're unique in the world.
96
235000
2000
04:12
These are animals that can practically swim
97
237000
2000
04:14
from the equator to the poles
98
239000
2000
04:16
and can crisscross entire oceans in the course of a year.
99
241000
3000
04:19
If we weren't so efficient at catching them, because they grow their entire life,
100
244000
3000
04:22
would have 30-year-old bluefin out there that weigh a ton.
101
247000
2000
04:24
But the truth is we're way too efficient at catching them,
102
249000
3000
04:27
and their stocks have collapsed worldwide.
103
252000
2000
04:29
This is the daily auction at the Tsukiji Fish Market
104
254000
2000
04:31
that I photographed a couple years ago.
105
256000
2000
04:33
And every single day these tuna, bluefin like this,
106
258000
3000
04:36
are stacked up like cordwood,
107
261000
2000
04:38
just warehouse after warehouse.
108
263000
2000
04:40
As I wandered around and made these pictures,
109
265000
2000
04:42
it sort of occurred to me that the ocean's not a grocery store, you know.
110
267000
3000
04:45
We can't keep taking without expecting
111
270000
2000
04:47
serious consequences as a result.
112
272000
3000
04:50
I also, with the story, wanted to show readers
113
275000
2000
04:52
how fish are caught, some of the methods that are used to catch fish,
114
277000
3000
04:55
like a bottom trawler, which is one of the most common methods in the world.
115
280000
3000
04:58
This was a small net that was being used in Mexico to catch shrimp,
116
283000
3000
05:01
but the way it works is essentially the same everywhere in the world.
117
286000
3000
05:04
You have a large net in the middle
118
289000
2000
05:06
with two steel doors on either end.
119
291000
2000
05:08
And as this assembly is towed through the water,
120
293000
2000
05:10
the doors meet resistance with the ocean,
121
295000
2000
05:12
and it opens the mouth of the net,
122
297000
2000
05:14
and they place floats at the top and a lead line on the bottom.
123
299000
3000
05:17
And this just drags over the bottom, in this case to catch shrimp.
124
302000
3000
05:20
But as you can imagine, it's catching everything else in its path as well.
125
305000
3000
05:23
And it's destroying that precious benthic community on the bottom,
126
308000
3000
05:26
things like sponges and corals,
127
311000
2000
05:28
that critical habitat for other animals.
128
313000
2000
05:30
This photograph I made of the fisherman
129
315000
3000
05:33
holding the shrimp that he caught after towing his nets for one hour.
130
318000
3000
05:36
So he had a handful of shrimp, maybe seven or eight shrimp,
131
321000
2000
05:38
and all those other animals on the deck of the boat are bycatch.
132
323000
3000
05:41
These are animals that died in the process,
133
326000
2000
05:43
but have no commercial value.
134
328000
2000
05:45
So this is the true cost of a shrimp dinner,
135
330000
2000
05:47
maybe seven or eight shrimp
136
332000
2000
05:49
and 10 pounds of other animals that had to die in the process.
137
334000
3000
05:52
And to make that point even more visual, I swam under the shrimp boat
138
337000
3000
05:55
and made this picture of the guy shoveling
139
340000
2000
05:57
this bycatch into the sea as trash
140
342000
2000
05:59
and photographed this cascade of death,
141
344000
2000
06:01
you know, animals like guitarfish, bat rays,
142
346000
3000
06:04
flounder, pufferfish, that only an hour before,
143
349000
3000
06:07
were on the bottom of the ocean, alive,
144
352000
2000
06:09
but now being thrown back as trash.
145
354000
2000
06:11
I also wanted to focus on the shark fishing industry
146
356000
3000
06:14
because, currently on planet Earth,
147
359000
2000
06:16
we're killing over 100 million sharks
148
361000
2000
06:18
every single year.
149
363000
2000
06:20
But before I went out to photograph this component,
150
365000
2000
06:22
I sort of wrestled with the notion of how do you make a picture of a dead shark
151
367000
3000
06:25
that will resonate with readers
152
370000
2000
06:27
You know, I think there's still a lot of people out there who think
153
372000
2000
06:29
the only good shark is a dead shark.
154
374000
2000
06:31
But this one morning I jumped in and found this thresher
155
376000
2000
06:33
that had just recently died in the gill net.
156
378000
2000
06:35
And with its huge pectoral fins and eyes still very visible,
157
380000
3000
06:38
it struck me as sort of a crucifixion, if you will.
158
383000
3000
06:41
This ended up being the lead picture
159
386000
2000
06:43
in the global fishery story in National Geographic.
160
388000
2000
06:45
And I hope that it helped readers to take notice
161
390000
2000
06:47
of this problem of 100 million sharks.
162
392000
3000
06:50
And because I love sharks -- I'm somewhat obsessed with sharks --
163
395000
3000
06:53
I wanted to do another, more celebratory, story about sharks,
164
398000
2000
06:55
as a way of talking about the need for shark conservation.
165
400000
3000
06:58
So I went to the Bahamas
166
403000
2000
07:00
because there're very few places in the world
167
405000
2000
07:02
where sharks are doing well these days,
168
407000
2000
07:04
but the Bahamas seem to be a place where stocks were reasonably healthy,
169
409000
3000
07:07
largely due to the fact that the government there
170
412000
3000
07:10
had outlawed longlining several years ago.
171
415000
2000
07:12
And I wanted to show several species
172
417000
2000
07:14
that we hadn't shown much in the magazine and worked in a number of locations.
173
419000
3000
07:17
One of the locations was this place called Tiger Beach,
174
422000
3000
07:20
in the northern Bahamas where tiger sharks
175
425000
2000
07:22
aggregate in shallow water.
176
427000
2000
07:24
This is a low-altitude photograph that I made
177
429000
2000
07:26
showing our dive boat with about a dozen of these big old tiger sharks
178
431000
3000
07:29
sort of just swimming around behind.
179
434000
2000
07:31
But the one thing I definitely didn't want to do with this coverage
180
436000
3000
07:34
was to continue to portray sharks as something like monsters.
181
439000
3000
07:37
I didn't want them to be overly threatening or scary.
182
442000
3000
07:40
And with this photograph of a beautiful
183
445000
2000
07:42
15-feet, probably 14-feet, I guess,
184
447000
2000
07:44
female tiger shark,
185
449000
2000
07:46
I sort of think I got to that goal,
186
451000
3000
07:49
where she was swimming with these little barjacks off her nose,
187
454000
3000
07:52
and my strobe created a shadow on her face.
188
457000
2000
07:54
And I think it's a gentler picture, a little less threatening,
189
459000
2000
07:56
a little more respectful of the species.
190
461000
2000
07:58
I also searched on this story
191
463000
2000
08:00
for the elusive great hammerhead,
192
465000
2000
08:02
an animal that really hadn't been photographed much
193
467000
2000
08:04
until maybe about seven or 10 years ago.
194
469000
2000
08:06
It's a very solitary creature.
195
471000
2000
08:08
But this is an animal that's considered data deficient by science
196
473000
3000
08:11
in both Florida and in the Bahamas.
197
476000
2000
08:13
You know, we know almost nothing about them.
198
478000
2000
08:15
We don't know where they migrate to or from,
199
480000
2000
08:17
where they mate, where they have their pups,
200
482000
2000
08:19
and yet, hammerhead populations in the Atlantic
201
484000
2000
08:21
have declined about 80 percent in the last 20 to 30 years.
202
486000
3000
08:24
You know, we're losing them faster than we can possibly find them.
203
489000
3000
08:27
This is the oceanic whitetip shark,
204
492000
3000
08:30
an animal that is considered the fourth most dangerous species,
205
495000
2000
08:32
if you pay attention to such lists.
206
497000
2000
08:34
But it's an animal that's about 98 percent in decline
207
499000
3000
08:37
throughout most of its range.
208
502000
2000
08:39
Because this is a pelagic animal and it lives out in the deeper water,
209
504000
3000
08:42
and because we weren't working on the bottom,
210
507000
2000
08:44
I brought along a shark cage here,
211
509000
2000
08:46
and my friend, shark biologist Wes Pratt is inside the cage.
212
511000
3000
08:49
You'll see that the photographer, of course, was not inside the cage here,
213
514000
3000
08:52
so clearly the biologist is a little smarter than the photographer I guess.
214
517000
3000
08:55
And lastly with this story,
215
520000
2000
08:57
I also wanted to focus on baby sharks, shark nurseries.
216
522000
3000
09:00
And I went to the island of Bimini, in the Bahamas,
217
525000
3000
09:03
to work with lemon shark pups.
218
528000
2000
09:05
This is a photo of a lemon shark pup,
219
530000
2000
09:07
and it shows these animals where they live for the first two to three years of their lives
220
532000
3000
09:10
in these protective mangroves.
221
535000
2000
09:12
This is a very sort of un-shark-like photograph.
222
537000
3000
09:15
It's not what you typically might think of as a shark picture.
223
540000
3000
09:18
But, you know, here we see a shark that's maybe 10 or 11 inches long
224
543000
3000
09:21
swimming in about a foot of water.
225
546000
2000
09:23
But this is crucial habitat and it's where they spend the first two, three years of their lives,
226
548000
3000
09:26
until they're big enough to go out on the rest of the reef.
227
551000
3000
09:29
After I left Bimini, I actually learned
228
554000
2000
09:31
that this habitat was being bulldozed
229
556000
2000
09:33
to create a new golf course and resort.
230
558000
3000
09:36
And other recent stories have looked at
231
561000
2000
09:38
single, flagship species, if you will,
232
563000
2000
09:40
that are at risk in the ocean
233
565000
2000
09:42
as a way of talking about other threats.
234
567000
3000
09:45
One such story I did documented the leatherback sea turtle.
235
570000
3000
09:48
This is the largest, widest-ranging,
236
573000
2000
09:50
deepest-diving and oldest of all turtle species.
237
575000
3000
09:53
Here we see a female crawling
238
578000
2000
09:55
out of the ocean under moonlight
239
580000
2000
09:57
on the island of Trinidad.
240
582000
2000
09:59
These are animals whose lineage dates back about 100 million years.
241
584000
3000
10:02
And there was a time in their lifespan
242
587000
2000
10:04
where they were coming out of the water to nest
243
589000
2000
10:06
and saw Tyrannosaurus rex running by.
244
591000
2000
10:08
And today, they crawl out and see condominiums.
245
593000
3000
10:11
But despite this amazing longevity,
246
596000
2000
10:13
they're now considered critically endangered.
247
598000
3000
10:16
In the Pacific, where I made this photograph,
248
601000
2000
10:18
their stocks have declined about 90 percent
249
603000
2000
10:20
in the last 15 years.
250
605000
2000
10:22
This is a photograph that shows a hatchling
251
607000
3000
10:25
about to taste saltwater for the very first time
252
610000
2000
10:27
beginning this long and perilous journey.
253
612000
2000
10:29
Only one in a thousand
254
614000
2000
10:31
leatherback hatchlings will reach maturity.
255
616000
2000
10:33
But that's due to natural predators
256
618000
2000
10:35
like vultures that pick them off on a beach
257
620000
2000
10:37
or predatory fish that are waiting offshore.
258
622000
3000
10:40
Nature has learned to compensate with that,
259
625000
2000
10:42
and females have multiple clutches of eggs
260
627000
2000
10:44
to overcome those odds.
261
629000
2000
10:46
But what they can't deal with is anthropogenic stresses,
262
631000
3000
10:49
human things, like this picture that shows
263
634000
2000
10:51
a leatherback caught at night in a gill net.
264
636000
3000
10:54
I actually jumped in and photographed this,
265
639000
2000
10:56
and with the fisherman's permission,
266
641000
2000
10:58
I cut the turtle out, and it was able to swim free.
267
643000
2000
11:00
But, you know, thousands of other leatherbacks each year
268
645000
3000
11:03
are not so fortunate,
269
648000
2000
11:05
and the species' future is in great danger.
270
650000
2000
11:07
Another charismatic megafauna species that I worked with
271
652000
3000
11:10
is the story I did on the right whale.
272
655000
2000
11:12
And essentially, the story is this with right whales,
273
657000
2000
11:14
that about a million years ago, there was
274
659000
2000
11:16
one species of right whale on the planet,
275
661000
2000
11:18
but as land masses moved around and oceans became isolated,
276
663000
3000
11:21
the species sort of separated,
277
666000
2000
11:23
and today we have essentially two distinct stocks.
278
668000
2000
11:25
We have the Southern right whale that we see here
279
670000
2000
11:27
and the North Atlantic right whale that we see here
280
672000
3000
11:30
with a mom and calf off the coast of Florida.
281
675000
2000
11:32
Now, both species were hunted to the brink of extinction
282
677000
2000
11:34
by the early whalers,
283
679000
2000
11:36
but the Southern right whales have rebounded a lot better
284
681000
2000
11:38
because they're located in places
285
683000
2000
11:40
farther away from human activity.
286
685000
2000
11:42
The North Atlantic right whale is listed as
287
687000
2000
11:44
the most endangered species on the planet today
288
689000
2000
11:46
because they are urban whales; they live along the east coast
289
691000
3000
11:49
of North America, United States and Canada,
290
694000
2000
11:51
and they have to deal with all these urban ills.
291
696000
3000
11:54
This photo shows an animal popping its head out at sunset off the coast of Florida.
292
699000
3000
11:57
You can see the coal burning plant in the background.
293
702000
3000
12:00
They have to deal with things like toxins and pharmaceuticals
294
705000
2000
12:02
that are flushed out into the ocean,
295
707000
2000
12:04
and maybe even affecting their reproduction.
296
709000
2000
12:06
They also get entangled in fishing gear.
297
711000
2000
12:08
This is a picture that shows the tail of a right whale.
298
713000
3000
12:11
And those white markings are not natural markings.
299
716000
2000
12:13
These are entanglement scars.
300
718000
2000
12:15
72 percent of the population has such scars,
301
720000
3000
12:18
but most don't shed the gear, things like lobster traps and crab pots.
302
723000
3000
12:21
They hold on to them, and it eventually kills them.
303
726000
3000
12:24
And the other problem is they get hit by ships.
304
729000
2000
12:26
And this was an animal that was struck by a ship
305
731000
2000
12:28
in Nova Scotia, Canada
306
733000
2000
12:30
being towed in, where they did a necropsy
307
735000
2000
12:32
to confirm the cause of death,
308
737000
2000
12:34
which was indeed a ship strike.
309
739000
2000
12:36
So all of these ills are stacking up against these animals
310
741000
3000
12:39
and keeping their numbers very low.
311
744000
2000
12:41
And to draw a contrast with that beleaguered North Atlantic population,
312
746000
3000
12:44
I went to a new pristine population of Southern right whales
313
749000
3000
12:47
that had only been discovered about 10 years ago
314
752000
2000
12:49
in the sub-Antarctic of New Zealand, a place called the Auckland Islands.
315
754000
3000
12:52
I went down there in the winter time.
316
757000
2000
12:54
And these are animals that had never seen humans before,
317
759000
2000
12:56
and I was one of the first people they probably had ever seen.
318
761000
2000
12:58
And I got in the water with them,
319
763000
2000
13:00
and I was amazed at how curious they were.
320
765000
2000
13:02
This photograph shows my assistant standing on the bottom at about 70 feet
321
767000
3000
13:05
and one of these amazingly beautiful, 45-foot,
322
770000
3000
13:08
70-ton whales,
323
773000
2000
13:10
like a city bus just swimming up, you know.
324
775000
2000
13:12
They were in perfect condition,
325
777000
2000
13:14
very fat and healthy, robust, no entanglement scars,
326
779000
3000
13:17
the way they're supposed to look.
327
782000
2000
13:19
You know, I read that the pilgrims, when they landed at Plymouth Rock
328
784000
2000
13:21
in Massachusetts in 1620,
329
786000
2000
13:23
wrote that you could walk across Cape Cod Bay
330
788000
2000
13:25
on the backs of right whales.
331
790000
2000
13:27
And we can't go back and see that today,
332
792000
2000
13:29
but maybe we can preserve what we have left.
333
794000
2000
13:31
And I wanted to close this program with a story of hope,
334
796000
3000
13:34
a story I did on marine reserves
335
799000
2000
13:36
as sort of a solution
336
801000
2000
13:38
to the problem of overfishing, the global fish crisis story.
337
803000
3000
13:41
I settled on working in the country of New Zealand
338
806000
2000
13:43
because New Zealand was rather progressive,
339
808000
2000
13:45
and is rather progressive in terms of protecting their ocean.
340
810000
3000
13:48
And I really wanted this story to be about three things:
341
813000
2000
13:50
I wanted it to be about abundance,
342
815000
2000
13:52
about diversity and about resilience.
343
817000
2000
13:54
And one of the first places I worked
344
819000
2000
13:56
was a reserve called Goat Island
345
821000
2000
13:58
in Leigh of New Zealand.
346
823000
2000
14:00
What the scientists there told me was that
347
825000
2000
14:02
when protected this first marine reserve in 1975,
348
827000
3000
14:05
they hoped and expected that certain things might happen.
349
830000
3000
14:08
For example, they hoped that certain species of fish
350
833000
2000
14:10
like the New Zealand snapper would return
351
835000
2000
14:12
because they had been fished to the brink of commercial extinction.
352
837000
3000
14:15
And they did come back. What they couldn't predict was that other things would happen.
353
840000
3000
14:18
For example, these fish
354
843000
2000
14:20
predate on sea urchins,
355
845000
2000
14:22
and when the fish were all gone,
356
847000
2000
14:24
all anyone ever saw underwater
357
849000
2000
14:26
was just acres and acres of sea urchins.
358
851000
3000
14:29
But when the fish came back
359
854000
2000
14:31
and began predating and controlling the urchin population,
360
856000
2000
14:33
low and behold, kelp forests emerged in shallow water.
361
858000
3000
14:36
And that's because the urchins eat kelp.
362
861000
3000
14:39
So when the fish control the urchin population,
363
864000
3000
14:42
the ocean was restored to its natural equilibrium.
364
867000
2000
14:44
You know, this is probably how the ocean looked here
365
869000
2000
14:46
one or 200 years ago, but nobody was around to tell us.
366
871000
3000
14:49
I worked in other parts of New Zealand as well,
367
874000
2000
14:51
in beautiful, fragile, protected areas
368
876000
3000
14:54
like in Fiordland, where this sea pen colony was found.
369
879000
3000
14:57
Little blue cod swimming in for a dash of color.
370
882000
3000
15:00
In the northern part of New Zealand,
371
885000
2000
15:02
I dove in the blue water, where the water's a little warmer,
372
887000
3000
15:05
and photographed animals like this giant sting ray
373
890000
2000
15:07
swimming through an underwater canyon.
374
892000
2000
15:09
Every part of the ecosystem in this place
375
894000
2000
15:11
seems very healthy,
376
896000
2000
15:13
from tiny, little animals like a nudibrank
377
898000
2000
15:15
crawling over encrusting sponge
378
900000
2000
15:17
or a leatherjacket
379
902000
2000
15:19
that is a very important animal in this ecosystem
380
904000
2000
15:21
because it grazes on the bottom and allows new life to take hold.
381
906000
3000

And I wanted to finish with this photograph,
382
910000
2000
15:27
a picture I made on a very stormy day in New Zealand
383
912000
3000
15:30
when I just laid on the bottom
384
915000
2000
15:32
amidst a school of fish swirling around me.
385
917000
2000
15:34
And I was in a place that had only been protected
386
919000
2000
15:36
about 20 years ago.
387
921000
2000
15:38
And I talked to divers that had been diving there for many years,
388
923000
3000
15:41
and they said that the marine life was better here today
389
926000
2000
15:43
than it was in the 1960s.
390
928000
2000
15:45
And that's because it's been protected,
391
930000
2000
15:47
that it has come back.
392
932000
2000
15:49
So I think the message is clear.
393
934000
2000
15:51
The ocean is, indeed, resilient and tolerant to a point,
394
936000
3000
15:54
but we must be good custodians.
395
939000
2000
15:56
I became an underwater photographer
396
941000
2000
15:58
because I fell in love with the sea,
397
943000
2000
16:00
and I make pictures of it today because I want to protect it,
398
945000
3000
16:03
and I don't think it's too late.
399
948000
2000
16:05
Thank you very much.
