In 2017, I confided in a dear friend of mine
0
4292
4380
00:09
that my lifelong wish was to see the blue whales.
1
9381
3003
00:14
Before I knew it, I found myself with a bunch of researchers
2
14261
4296
00:18
in the Sea of Cortez studying the blue whales.
3
18598
3128
00:22
We used to be in a boat 25 foot long.
4
22978
3086
00:27
And next to us ...
5
27190
1251
00:30
is this majestic creature
6
30986
3753
00:35
feeding gracefully next to us.
7
35490
2169
00:39
Now you have to understand, at that point in time,
8
39327
2419
00:41
I knew nothing about blue whales, or whales in general.
9
41746
2586
00:44
I'm just a financial economist.
10
44374
1668
00:47
But I learned something from them, which was really incredible.
11
47168
3712
00:50
It was already known in the science that whales capture so much carbon
12
50922
6882
00:58
on their body and indirectly.
13
58972
3378
01:03
And that's, of course, very important for us
14
63727
2460
01:06
because we are all facing the climate calamity
15
66187
3671
01:09
and we are all talking about how to grab carbon dioxide
16
69858
3253
01:13
from the atmosphere.
17
73111
1835
01:14
Well, it turns out that the whales
18
74946
2753
01:17
grab so much carbon dioxide from the atmosphere --
19
77699
3045
01:20
by the way, they eat and they poop.
20
80744
2836
01:24
Yeah. It's all about food.
21
84623
1334
01:28
So how does the whale system work?
22
88335
2919
01:31
Well, it starts in the oceans.
23
91296
2252
01:34
There's these microscopic organisms called phytoplankton.
24
94507
3003
01:38
Those phytoplankton do something really incredible.
25
98470
2502
01:42
They grab so much carbon dioxide from the atmosphere,
26
102641
4212
01:46
and they return oxygen to all of us.
27
106895
3503
01:50
Now how much carbon dioxide do they grab from the atmosphere?
28
110398
3128
01:55
About 37 gigatons of carbon dioxide from the atmosphere.
29
115028
4880
02:00
Truly the lungs of the planet are in the ocean.
30
120825
3504
02:04
Now, if you want to visualize what 37 gigatons mean,
31
124329
3086
02:08
that's the equivalent of the carbon
32
128375
2585
02:11
that is grabbed by four Amazon forests per year.
33
131002
3420
02:15
That's how much is being sucked in by these photosynthetic organisms.
34
135382
4713
02:20
Now larger creatures called krill
35
140929
3837
02:24
love to eat phytoplankton directly or indirectly.
36
144808
3879
02:29
And the whales love to feed on the krill.
37
149688
3420
02:33
They feed so much on the krill that they grow bigger and bigger,
38
153108
3837
02:36
and they store carbon in their body.
39
156945
2210
02:39
How much carbon do they store in their body?
40
159948
2669
02:43
Roughly about seven to nine tons of carbon on their body.
41
163952
5005
02:49
If you want to convert that to carbon dioxide,
42
169916
2169
02:52
that's about 33 tons of carbon dioxide being kept out of the atmosphere
43
172085
4880
02:57
on the body of a single whale.
44
177006
1836
03:00
If you want to visualize that,
45
180343
1668
03:02
that’s the work of 1,500 trees
46
182053
3045
03:05
on the body of a single whale.
47
185140
1835
03:07
OK?
48
187892
1335
03:09
But those guys, because they eat a lot,
49
189269
3253
03:12
what do you do next?
50
192522
1293
03:13
You poop a lot.
51
193815
1251
03:15
And their poop turns out to be incredibly important
52
195900
2837
03:18
because it fertilizes the phyto.
53
198737
2210
03:21
So you have this wonderful cycle.
54
201740
2002
03:24
OK? The whale feeds on the krill, the krill feeds on the phyto,
55
204993
3795
03:28
and the phyto eats the poop of the whales to get more active.
56
208830
4046
03:32
And when the phyto gets more active,
57
212917
1752
03:34
it grabs more carbon dioxide from the atmosphere.
58
214711
3420
03:39
So just imagine: the whales, they capture carbon on their body.
59
219090
6090
03:45
Unfortunately, at some point they die,
60
225221
1877
03:47
and they're so heavy they sink to the bottom of the ocean.
61
227140
3837
03:51
And anything below a thousand meters is sequestered almost forever.
62
231019
4629
03:55
And through their poop they also fertilize phyto,
63
235648
2920
03:58
making phyto even more active,
64
238568
1752
04:00
grabbing more carbon dioxide from the atmosphere.
65
240320
2586
04:04
So in a sense, the whales are incredible allies
66
244199
3378
04:07
in the fight against climate change.
67
247577
2085
04:10
Now that's good news, right? Yeah.
68
250371
2253
04:13
Except that whales are dying.
69
253500
1668
04:16
They're dying from ship strikes.
70
256461
2210
04:18
They're dying from pollution, they're dying from entanglements.
71
258713
3921
04:24
In fact, they're dying because our current economic system
72
264552
4046
04:29
puts a zero value on a living whale.
73
269808
2961
04:33
But chop a whale, sell it for its meat, it acquires a value.
74
273561
4255
04:40
The value of a living whale is zero, zero dollars,
75
280443
4129
04:44
zero in any currency.
76
284572
1585
04:47
I'm a financial economist.
77
287325
1668
04:50
And I'm listening to these scientists bemoaning what's happening to the whales.
78
290286
4255
04:54
And I wanted to help. I didn't know how to help.
79
294582
2253
04:56
And I thought, wait a minute.
80
296876
1961
04:58
Maybe I can bring your message to the audiences around the world.
81
298878
5255
05:04
Maybe I can translate all of that value, those services they do for us
82
304175
5547
05:09
in a language that we can all understand.
83
309764
2669
05:12
Unfortunately, it's a language of dollars and cents.
84
312475
2628
05:16
So I set out with my team to value the services of a whale
85
316062
5547
05:21
but one service -- because the whales do a whole host of things.
86
321609
3587
05:25
But I just wanted to value one thing,
87
325196
1835
05:27
which is what is the value
88
327031
1710
05:28
of their carbon sequestration service to us?
89
328741
3587
05:32
Now how would you do something like that? After all, the whale is a living system.
90
332328
3921
05:36
The whale captures carbon on her body,
91
336291
2961
05:39
and she gives birth to baby whales
92
339294
1960
05:41
who also grow up to capture carbon on their body.
93
341296
2877
05:44
And they give birth to whales and so forth,
94
344215
3337
05:47
and indirectly through the fertilization of phyto.
95
347594
2377
05:50
So how would you do something like this?
96
350013
2502
05:52
Well, to do that,
97
352557
1501
05:54
I had to resort to what I do best, which is valuation.
98
354100
5255
05:59
I looked at it, I said, wait a minute.
99
359355
2294
06:01
This looks like a share of stock that pays dividends.
100
361649
3379
06:06
Except those dividends are live dividends. They give birth to more dividends.
101
366070
4380
06:11
So if I were to track the whale over her lifetime
102
371117
4505
06:15
and keep track of all these dividends
103
375622
2627
06:18
into the future,
104
378291
1251
06:20
and then multiply that by the price of carbon,
105
380585
3462
06:24
and discount that all the way to the present,
106
384088
4296
06:28
I can figure out what is the present value,
107
388426
2544
06:31
discounted present value,
108
391012
1376
06:32
of the lifetime earnings of a single whale.
109
392430
3128
06:36
Would you like to know how much?
110
396059
1543
06:37
(Applause)
111
397644
1418
06:40
Would you like to know how much?
112
400313
1627
06:41
Audience: Yes!
113
401940
1418
06:43
RC: At least three million dollars.
114
403816
2002
06:46
At least.
115
406694
1252
06:48
Because I'm leaving so much out of this.
116
408738
2794
06:51
But I just wanted to tell the good news that I heard on that boat.
117
411532
3421
06:54
I didn't know what to do. I was trying to help them out.
118
414953
2627
06:58
But there's more good news. Would you like to hear it?
119
418873
2544
07:01
Audience: Yes!
120
421459
1668
07:03
RC: Their cousins on land, the elephants in the forests of Africa,
121
423169
4713
07:07
in the Congo Basin,
122
427924
1251
07:09
they do the same thing.
123
429217
1334
07:11
Turns out the way they walk and they eat and they poop,
124
431511
4087
07:16
they increase carbon sequestration in the trees, in the forests
125
436432
4713
07:21
between seven and 14 percent.
126
441187
2669
07:24
Just imagine, just by frolicking around,
127
444774
2961
07:27
they're helping us to grab carbon dioxide from the atmosphere and fix it.
128
447735
5130
07:34
So I thought, hey, maybe, maybe we can value their services to.
129
454283
4964
07:40
Right? Same thing.
130
460206
2628
07:42
But again, use the same model of valuation.
131
462875
3838
07:46
You follow the same methodology,
132
466754
2253
07:49
and you discount all of that to the present.
133
469048
2086
07:51
And you ask yourself, what is the value
134
471134
2711
07:53
of a single elephant's carbon sequestration service?
135
473886
3754
07:58
Would you like to know how much?
136
478474
1585
08:00
Audience: Yes!
137
480101
1251
08:01
RC: Here we go.
138
481394
1460
08:02
2.6 million dollars.
139
482895
2419
08:07
Would you like to hear some more good news?
140
487358
2169
08:09
Audience: Yes!
141
489527
1293
08:10
RC: Aside from forests --
142
490820
1293
08:12
because we are land people, we just think of forests --
143
492113
2878
08:14
go a little bit into the water.
144
494991
2544
08:17
Seagrass, saltmarsh mangroves, kelp forests, peatlands, wetlands --
145
497535
5339
08:22
these are living systems that suck in so much carbon dioxide
146
502915
3671
08:26
beyond your imagination,
147
506627
1919
08:28
and they keep it forever in their roots
148
508588
2377
08:31
as long as you leave them alone and you look after them.
149
511007
2627
08:35
So ...
150
515094
1251
08:36
If you think these numbers are big,
151
516971
2211
08:39
wait till you see what I'm about to tell you next.
152
519974
3087
08:43
In seagrass alone,
153
523102
1794
08:44
seagrass alone, carbon sequestration.
154
524937
2211
08:47
How much do you think is the value of the global --
155
527857
3253
08:51
If you look at globally the seagrass
156
531110
1961
08:53
and you value their carbon sequestration service,
157
533071
3420
08:56
how much you think it's worth?
158
536491
1876
08:58
You ready?
159
538367
1252
09:00
2.3 trillion dollars.
160
540411
3003
09:03
That's the size of the German stock market.
161
543456
3670
09:10
Now.
162
550379
1544
09:11
What does this tell us?
163
551964
1836
09:13
This tells us that a living and thriving nature
164
553841
4630
09:18
is not only valuable intrinsically,
165
558513
3086
09:21
it's also financially valuable to us.
166
561641
3920
09:27
Question is, what do you do with this?
167
567438
2086
09:29
So the science tells us what a wondrous Earth we are on.
168
569524
3670
09:33
We can value it in dollars and cents.
169
573194
1793
09:34
Question is, what are you going to do with it?
170
574987
2253
09:37
Well, guess what? We can build a whole economy
171
577240
2252
09:39
around a living and thriving nature,
172
579492
2586
09:42
not an extractive view of nature,
173
582078
2210
09:44
but a regenerative view of nature.
174
584288
2294
09:47
And that economy --
175
587583
1335
09:48
(Applause)
176
588960
1168
09:50
Thank you.
177
590169
1251
09:51
That economy is going to deliver for us sustainable and shared prosperity
178
591462
6757
09:58
for all, big and small, all creatures on this planet.
179
598261
5422
10:03
It does not have to be I win, you lose.
180
603724
2795
10:06
It is a win-win.
181
606561
2294
10:08
I'm going to show you how.
182
608855
1376
10:11
From there we can build --
183
611315
2628
10:13
In order to build that economy, we need three things.
184
613943
2920
10:16
We need the science, the accounting, the scientific accounting.
185
616863
3336
10:20
What is it that you have? How much of it do you have?
186
620199
3963
10:24
Then people like me, financial economists, come around and they say,
187
624162
3211
10:27
"What is the value of what you have?"
188
627415
1793
10:29
The reason we value it is just to basically translate it
189
629250
2669
10:31
into the language that policymakers can understand
190
631961
2544
10:34
so they can make decisions.
191
634547
1710
10:36
That's all. It's a translation.
192
636299
2294
10:39
But then the third pillar is very important,
193
639427
2377
10:41
which is the legal framing.
194
641846
2252
10:44
The legal framing is very important
195
644140
2919
10:47
because we need to protect the rights of nature,
196
647101
2753
10:49
a living and thriving nature.
197
649896
2544
10:52
Three things. Once you do these three things,
198
652440

you can create markets around nature.

10:58
When I say markets around nature,
200
658654
1710
11:00
not an extractive view of nature, but a regenerative view of nature.
201
660364
4755
11:05
And I'm going to show you how.
202
665119
1752
11:06
I'm going to show you how.
203
666871

11:10
Gabon has 57,000 elephants.
204
670333
3670
11:15
If you leave them alone, they can grow to 195,000 elephants.
205
675213
4254
11:20
Gabon can sell the carbon offsets of its elephants.
206
680301
4630
11:24
Imagine -- because those elephants are grabbing carbon in the trees --
207
684972
3837
11:28
they can sell the carbon offsets of their elephants.
208
688851
3879
11:32
To whom?
209
692730
1710
11:34
To us because we're all enamored
210
694440
1710
11:36
with going carbon zero, carbon negative, carbon neutral.
211
696150
3420
11:40
And our money will come in to look after these elephants in perpetuity.
212
700947
4379
11:46
OK? So how much revenue can Gabon get out of it?
213
706744
4671
11:51
One billion dollars a year from allowing these elephants to frolic freely,
214
711457
6048
11:57
not be tied to anything,
215
717546
2253
11:59
just by leaving them alone.
216
719840
1919
12:01
Those elephants, by the way, they walk, they poop,
217
721801
2752
12:04
just being, having babies, doing whatever they do,
218
724595
3253
12:07
they help carbon sequestration in the forests.
219
727890
3212
12:11
A forest without animals is dead.
220
731143
2753
12:13
It's not about flora. It's about flora and fauna.
221
733896
3629
12:17
It's about nature itself.
222
737525
2169
12:19
That's what the message is.
223
739694
1334
12:21
Who would buy these carbon offsets?
224
741988
3336
12:25
All these companies and countries
225
745324
1669
12:26
that made commitments to carbon zero, carbon negative, carbon neutral.
226
746993
3712
12:31
They would buy the carbon offsets, or carbon credits if you like.
227
751622
4088
12:35
The money would flow in from these ecosystem services --
228
755751
4964
12:40
be it the whales, be it the elephants, be it mangrove, seagrass, saltmarsh --
229
760756
4338
12:45
and the money goes in by contract,
230
765136
2502
12:47
using blockchain technology to look after nature in perpetuity --
231
767680
5213
12:52
very important --
232
772935
1251
12:54
and to look after the stewards of nature in perpetuity.
233
774228
3504
12:57
And the stewards of nature are the local and the indigenous population.
234
777732
4713
13:02
They're the ones who are doing the conservation, not you and me.
235
782445
4379
13:06
(Applause)
236
786824
1919
13:12
Once we do that --
237
792288
2627
13:16
Notice what it is.
238
796000
1376
13:17
It's a win for nature.
239
797418
2794
13:20
It's a win for the economy.
240
800254
2461
13:22
The government will make money
241
802757
1459
13:24
because the government is going to get all that revenue.
242
804258
2628
13:26
It will change its fiscal stance.
243
806927
1627
13:28
It will diversify its economy. It will grow in a sustainable way.
244
808596
4004
13:34
It's a win for the environment.
245
814226
2128
13:36
It's a win for all of these creatures that have suffered so much at our hands.
246
816395
4672
13:42
It’s a win for this beautiful Earth of ours.
247
822902
3253
13:46
As Carl Sagan once said,
248
826989
1335
13:49
“The only Earth we’ll ever know.
249
829367
2419
13:52
The only home we'll ever know."
250
832745
1501
13:55
It's a win for us.
251
835873
1251
13:58
We are taking this work
252
838209
2335
14:00
in Africa to Liberia, Cameroon, Kenya, South Africa.
253
840586
4963
14:05
We're taking this work to the Americas, Chile, Argentina.
254
845591
3462
14:09
We're doing it in the US and in the UK.
255
849095
2961
14:15
Imagine, it just started with just a wish of mine to see a blue whale.
256
855142
5923
14:21
Little did I know it's going to end up with a vision
257
861065
3420
14:24
of how we ought to live for tomorrow.
258
864485
2628
14:28
Thank you.
