(雨林的聲音)
00:21
In the summer of 2011, as a tourist,
1
21680
3487
2011年夏天, 我以旅行者的身份,
00:25
I visited the rainforests of Borneo for the very first time,
2
25167
4426
第一次拜訪婆羅洲的雨林。
00:29
and as you might imagine,
3
29593
2048
你也許猜想到,
00:31
it was the overwhelming sounds of the forest that struck me the most.
4
31641
5270
我印象最深刻的, 是鋪天蓋地的雨林之聲。
00:36
There's this constant cacophony of noise.
5
36911
2810
有一個持續不斷的雜音。
00:39
Some things actually do stick out.
6
39721
2415
有一些聲音確實與眾不同。
00:42
For example, this here is a big bird, a rhinoceros hornbill.
7
42136
4426
例如,這有一隻大鳥, 是一隻犀鳥
00:46
This buzzing is a cicada.
8
46562
4172
這是蟬的鳴叫聲;
00:51
This is a family of gibbons.
9
51434
2613
這是一個長臂猿家族,
00:54
It's actually singing to each other over a great distance.
10
54047
4114
牠正向遠處的家人歌唱。
00:59
The place where this was recorded was in fact a gibbon reserve,
11
59341
2993
據記載,這地方 是一個長臂猿的保護區,
01:02
which is why you can hear so many of them,
12
62334
2037
因此可以聽到那麼多猿聲,
01:04
but in fact the most important noise that was coming out of the forest that time
13
64372
4930
但那時森林中最重要的聲音
01:09
was one that I didn't notice,
14
69302
1532
卻是我當時沒注意的聲音,
01:10
and in fact nobody there had actually noticed it.
15
70834
3109
事實上那裡沒有人 真的注意到那個聲音。
01:14
So, as I said, this was a gibbon reserve.
16
74373
1988
如我所說,這是長臂猿保護區。
01:16
They spend most of their time rehabilitating gibbons,
17
76361
2809
他們花了大部份時間復育長臂猿,
01:19
but they also have to spend a lot of their time
18
79170
2561
也花了大量時間
01:21
protecting their area from illegal logging that takes place on the side.
19
81731
3692
保護長臂猿的生長區域 不受邊境非法盜木所影響。
01:25
And so if we take the sound of the forest
20
85423
2043
如果我們收集森林的聲音,
01:27
and we actually turn down the gibbons, the insects, and the rest,
21
87466
3557
調降長臂猿、昆蟲 以及其他動物的聲音,
01:31
in the background, the entire time, in recordings you heard,
22
91023
3666
你可以在整段時間聽到背景中
01:34
was the sound of a chainsaw at great distance.
23
94689
3714
來自遠處的電鋸聲。
01:38
They had three full-time guards who were posted around this sanctuary
24
98403
3994
當地有三位全職警衛 戍守這個避護所,
01:42
whose job was in fact to guard against illegal logging,
25
102397
4202
面對面抵抗非法伐木。
01:46
and one day, we went walking, again as tourists, out into the forest,
26
106599
3459
而某天, 我們再次以旅者的身份走入雨林,
01:50
and within five minutes' walk,
27
110058
2253
5分鐘後,
01:52
we stumbled upon somebody who was just sawing a tree down,
28
112311
3379
我們看見了 有人剛剛把一顆樹鋸下來。
01:55
five minutes' walk, a few hundred meters from the ranger station.
29
115690
3261
就在5分鐘路程內, 離警衛駐點數百公尺之外。
01:58
They hadn't been able to hear the chainsaws,
30
118951
2058
他們從未聽到電鋸聲,
02:01
because as you heard, the forest is very, very loud.
31
121009
3817
因為如你所聽, 森林聲音非常、非常大。
02:04
It struck me as quite unacceptable that in this modern time,
32
124826
3919
這令我十分不解,在現代,
02:08
just a few hundred meters away from a ranger station in a sanctuary,
33
128745
4472
僅離警衛駐點數百公尺,
02:13
that in fact nobody could hear it when someone who has a chainsaw gets fired up.
34
133217
3805
竟然無人聽到有人在使用電鋸。
02:17
It sounds impossible, but in fact, it was quite true.
35
137022
4665
這聽來不可思議, 但事實上,這是十分真確的。
02:21
So how do we stop illegal logging?
36
141689
1834
那麼,我們如何停止非法伐木?
02:23
It's really tempting, as an engineer, always to come up with a high-tech,
37
143523
3429
這真令人技癢, 工程師總想要高科技,
想出超瘋狂高科技解決方案,
02:26
super-crazy high-tech solution,
38
146952
1761
02:28
but in fact, you're in the rainforest.
39
148713
1950
但事實上,你身處雨林,
02:30
It has to be simple, it has to be scalable,
40
150663
2377
這個方法必須簡單、易操作,
02:33
and so what we also noticed while were there was that
41
153040
3008
而我們注意到
02:36
everything we needed was already there.
42
156048
2326
我們所需的都已經在那裡了。
02:38
We could build a system that would allow us to stop this
43
158374
2751
我們可以構架一個系統,
02:41
using what's already there.
44
161125
2282
就地取材阻止盜伐。
02:43
Who was there? What was already in the forest?
45
163407
2232
誰在那?森林裡有什麼?
02:45
Well, we had people.
46
165639
1148
我們有人手,
02:46
We had this group there that was dedicated, three full-time guards,
47
166787
3285
我們有3位全職警衛,
02:50
that was dedicated to go and stop it,
48
170072
1774
其職責就是阻止盜木,
02:51
but they just needed to know what was happening out in the forest.
49
171846
3114
而他們需要的是 知道森林裡發生了什麼事。
02:54
The real surprise, this is the big one,
50
174960
1893
令人驚訝,超乎預期的是,
02:56
was that there was connectivity out in the forest.
51
176853
2383
森林裡有網路連結訊號!
02:59
There was cell phone service way out in the middle of nowhere.
52
179236
2914
手機服務訊號在雨林中無所不在,
03:02
We're talking hundreds of kilometers from the nearest road,
53
182150
2931
我們談的是距道路數百公里之遙,
03:05
there's certainly no electricity, but they had very good cell phone service,
54
185081
3572
當然沒有電力, 但卻有很好的手機訊號,
03:08
these people in the towns were on Facebook all the time,
55
188653
2623
城鎮中的人們 總是掛在Facebook,
03:11
they're surfing the web on their phones,
56
191276
1950
用他們的手機瀏覽網路,
03:13
and this sort of got me thinking that in fact it would be possible
57
193226
3109
而這讓我想到也許可以
03:16
to use the sounds of the forest,
58
196335
2159
利用森林裡的聲音,
03:18
pick up the sounds of chainsaws programmatically,
59
198494
2392
用程序擷取電鋸的音頻,
03:20
because people can't hear them,
60
200886
1648
因為人們無法聽到,
03:22
and send an alert.
61
202534
1687
並送出警示。
03:24
But you have to have a device to go up in the trees.
62
204221
2582
但必須把某個設備放在樹上;
03:26
So if we can use some device to listen to the sounds of the forest,
63
206803
3651
如果我們可以運用某些設備 來聽取森林的聲音,
03:30
connect to the cell phone network that's there,
64
210454
2233
連結到手機的網絡,
03:32
and send an alert to people on the ground,
65
212687
2034
將警示傳送給地面上的人們;
03:34
perhaps we could have a solution to this issue for them.
66
214721
3550
或許,我們可以 為他們找到解決方案。
03:38
But let's take a moment to talk about saving the rainforest,
67
218271
3280
但我們先來談談拯救雨林,
03:41
because it's something that we've definitely all heard about forever.
68
221551
3842
因為那是我們聽聞已久的事情。
03:45
People in my generation have heard about saving the rainforest
69
225393
2919
與我同輩的人都聽過拯救雨林,
03:48
since we were kids,
70
228312
1900
從我們還是孩子的時候,
03:50
and it seems that the message has never changed:
71
230212
2248
而這似乎未曾改變,
03:52
We've got to save the rainforest, it's super urgent,
72
232460
2522
我們要拯救雨林,這超級迫切,
03:54
this many football fields have been destroyed yesterday.
73
234982
2706
如此多足球場般大的雨林 昨日已被摧毀。
03:57
and yet here we are today, about half of the rainforest remains,
74
237688
3304
而今,仍有半數的雨林存在著,
04:00
and we have potentially more urgent problems like climate change.
75
240992
4327
我們已有潛在更迫切的問題, 例如氣候變遷。
04:05
But in fact, this is the little-known fact that I didn't realize at the time:
76
245319
3909
但,有一些少為人知的事實 我當時並不知道
04:09
Deforestation accounts for more greenhouse gas
77
249228
2961
[13%運輸;17%伐木] 伐木造成的溫室氣體
04:12
than all of the world's planes, trains, cars, trucks and ships combined.
78
252189
4040
比全世界的飛機、火車、汽車、 卡車、船運加總還要多,
04:16
It's the second highest contributor to climate change.
79
256229
2716
是造成氣候變遷的第二大起因。
04:18
Also, according to Interpol,
80
258945
2833
同時,根據國際刑警組織,
04:21
as much as 90 percent of the logging that takes place in the rainforest
81
261778
3529
雨林區的伐木有高達90%
04:25
is illegal logging, like the illegal logging that we saw.
82
265307
3781
都是違法的, 就像我們所看到的盜伐。
04:29
So if we can help people in the forest enforce the rules that are there,
83
269088
4044
若我們能幫助雨林的人們 執行當地的法律,
04:33
then in fact we could eat heavily into this 17 percent
84
273132
3924
我們可以減少 高達17%的溫室氣體,
04:37
and potentially have a major impact in the short term.
85
277056
2611
並可在短期產生重大影響。
04:39
It might just be the cheapest, fastest way to fight climate change.
86
279667
5165
這也許是擊退氣候變遷 最便宜、最快速的方法。
04:44
And so here's the system that we imagine.
87
284832
1998
這是我們構想的系統,
04:46
It looks super high tech.
88
286830
1194
看起來像超高端科技。
04:48
The moment a sound of a chainsaw is heard in the forest,
89
288024
2633
當電鋸的聲音在森林中被聽到,
04:50
the device picks up the sound of the chainsaw,
90
290657
2172
這個設備擷取電鋸的聲音,
04:52
it sends an alert through the standard GSM network that's already there
91
292829
3607
透過現有的標準GSM網絡 發出警示
04:56
to a ranger in the field
92
296436
2087
給當地的警衛,
04:58
who can in fact show up in real time and stop the logging.
93
298523
2817
他們就可以即時出現,阻止砍伐。
05:01
It's no more about going out and finding a tree that's been cut.
94
301340
3909
這不需要走到外面, 才發現樹木被砍了。
05:05
It's not about seeing a tree from a satellite
95
305249
2176
也不必看區域衛星圖
05:07
in an area that's been clear cut,
96
307425
1636
看有沒有樹被砍倒,
05:09
it's about real-time intervention.
97
309061
2198
這是即時的干預。
05:11
So I said it was the cheapest and fastest way to do it,
98
311669
2721
如我所說, 這是最便宜、最快速的方法,
05:14
but in fact, actually, as you saw, they weren't able to do it,
99
314390
2925
但事實上,如你所見, 他們無法做到,
05:17
so it may not be so cheap and fast.
100
317315
1884
所以它也許不是那麼便宜、快速。
05:19
But if the devices in the trees were actually cell phones,
101
319199
3436
但如果樹上的設備是手機的話,
05:22
it could be pretty cheap.
102
322635
1556
那可以是非常便宜的。
05:24
Cell phones are thrown away by the hundreds of millions every year,
103
324191
4287
每年有數以億計的手機被丟棄,
05:28
hundreds of millions in the U.S. alone,
104
328478
2121
僅在美國就有上億部,
05:30
not counting the rest of the world, which of course we should do,
105
330599
3181
這還沒算到世界其他地區, 當然我們應該算到;
05:33
but in fact, cell phones are great.
106
333780
2531
但事實上,手機是很棒的!
05:36
They're full of sensors.
107
336311
1333
手機充滿感測器
05:37
They can listen to the sounds of the forest.
108
337644
2152
可以聽取森林的聲音;
05:39
We do have to protect them.
109
339796
1382
我們需要保護手機,
05:41
We have to put them in this box that you see here,
110
341178
2407
我們需要把手機放在盒子裡, 如你在此所見。
05:43
and we do have to power them.
111
343585
1567
我們需要替手機充電,
05:45
Powering them is one of the greater engineering challenges
112
345152
2763
替手機充電一項重大工程挑戰,
05:47
that we had to deal with,
113
347915
1300
我們必須面對,
05:49
because powering a cell phone under a tree canopy,
114
349215
2752
因為在樹蔭下替手機充電,
05:51
any sort of solar power under a tree canopy,
115
351967
2252
任何在樹蔭下的太陽能,
05:54
was an as-yet-unsolved problem,
116
354219
1810
都尚未做到;
05:56
and that's this unique solar panel design that you see here,
117
356029
2857
而這就是獨一無二的 太陽能面板設計,
05:58
which in fact is built also from recycled byproducts of an industrial process.
118
358886
4319
這是由工廠製程中 回收的副產品所組成的,
06:03
These are strips that are cut down.
119
363205
2624
這些是剩下的腳料。
06:05
So this is me putting it all together
120
365829
3506
這是我, 正將所有東西組裝在一起,
06:09
in my parents' garage, actually.
121
369335
1881
在我父母的車庫中,
06:11
Thanks very much to them for allowing me to do that.
122
371216
2577
非常感謝他們允許我這麼作。
06:13
As you can see, this is a device up in a tree.
123
373793
4356
如你所見, 這套設備在樹上的樣子。
06:18
What you can see from here, perhaps, is that they are pretty well obscured
124
378149
3585
如你所見,樹上的這些設備,
06:21
up in the tree canopy at a distance.
125
381734
1802
從遠方看起來很不顯眼。
06:23
That's important, because although they are able to hear chainsaw noises
126
383536
3477
那很重要,雖然它們可以聽到
06:27
up to a kilometer in the distance,
127
387013
1770
遠至一公里之外的電鋸聲,
06:28
allowing them to cover about three square kilometers,
128
388783
2520
範圍可覆蓋約3平方公里,
06:31
if someone were to take them, it would make the area unprotected.
129
391303
3178
但如果有人把它拿走, 這個區域就不受保護了。
06:35
So does it actually work?
130
395281
2753
這真的行得通嗎?
06:38
Well, to test it, we took it back to Indonesia,
131
398034
2972
嗯,來試試看, 我們帶著它回到印尼,
06:41
not the same place, but another place,
132
401006
2113
不是同個地方,而是另一個地方,
06:43
to another gibbon reserve
133
403119
1671
去到另一個長臂猿保護區,
06:44
that was threatened daily by illegal logging.
134
404790
2845
天天被盜伐威脅的保護區。
06:48
On the very second day, it picked up illegal chainsaw noises.
135
408505
3919
就在第二天, 它擷取到非法的電鋸聲,
06:52
We were able to get a real-time alert.
136
412424
2199
我們能夠得到一個即時的警示,
06:54
I got an email on my phone.
137
414623
1347
我在手機上收到郵件。
06:55
Actually, we had just climbed the tree. Everyone had just gotten back down.
138
415970
3716
事實上,我們剛爬完樹, 大家才剛回到地面,
06:59
All these guys are smoking cigarettes,
139
419686
2240
大夥正在抽煙,
07:01
and then I get an email, and they all quiet down,
140
421926
2857
然後我收到郵件,他們都安靜下來,
07:04
and in fact you can hear the chainsaw
141
424783
2104
事實上你可以聽到電鋸聲,
07:06
really, really faint in the background,
142
426887
1929
在背景聲中非常非常模糊的聲音,
07:08
but no one had noticed it until that moment.
143
428816
2305
但直到警示響起時大家才注意到。
07:11
And so then we took off to actually stop these loggers.
144
431121
3274
接著,我們動身前去阻止伐木者;
07:14
I was pretty nervous.
145
434395
1509
我十分緊張,
07:15
This is the moment where we've actually arrived close to where the loggers are.
146
435904
4226
那時我們到達伐木人附近,
07:20
This is the moment where you can see where I'm actually regretting
147
440130
3114
這時我也許之前的所有努力 開始感到後悔,
07:23
perhaps the entire endeavor.

這時我也許對之前所有的努力 開始感到後悔,
07:25
I'm not really sure what's on the other side of this hill.
149
445245
2743
我不確定山坡另一邊的狀況。
07:27
That guy's much braver than I am.
150
447988
1963
那位老兄比我勇敢得多,
07:29
But he went, so I had to go, walking up,
151
449951
4180
但他去了,所以我必須去,
07:34
and in fact, he made it over the hill,
152
454131
2159
他登上山坡,
07:36
and interrupted the loggers in the act.
153
456290
3237
中斷伐木者的行動。
07:39
For them, it was such a surprise --
154
459527
1662
對他們而言,這非常令人驚訝---
07:41
they had never, ever been interrupted before --
155
461189
2380
他們之前從來沒有被中斷過---
07:43
that it was such an impressive event for them,
156
463569
2165
這對他們來說相當印象深刻,
07:45
that we've heard from our partners they have not been back since.
157
465734
3116
後來夥伴們告訴我們, 自此之後他們再也沒來。
07:48
They were, in fact, great guys.
158
468850
1492
他們真的是很棒的人!
07:50
They showed us how the entire operation works,
159
470342
2180
他們展示這個運作是可行的,
07:52
and what they really convinced us on the spot was that
160
472522
2574
他們當場使我們相信:
07:55
if you can show up in real time and stop people,
161
475096
2245
如果你可以即時出現、阻止伐木者,
07:57
it's enough of a deterrent they won't come back.
162
477341
4182
那會有很足夠的嚇阻作用 讓他們不再回來。
08:01
So --
163
481529
1556
所以
08:03
Thank you. (Applause)
164
483085
4991
謝謝 (掌聲)
08:09
Word of this spread, possibly because we told a lot of people,
165
489586
3854
這件事情廣泛流傳了, 也許是因為我們跟很多人說過了,
08:13
and in fact, then some really amazing stuff started to happen.
166
493440
3437
而事實上, 後來有些令人驚喜的東西開始發生。
08:16
People from around the world started to send us emails, phone calls.
167
496877
3669
世界各地的人們 開始寄郵件和手機給我們,
08:20
What we saw was that people throughout Asia,
168
500546
2089
我們看到來自亞洲、
08:22
people throughout Africa, people throughout South America,
169
502635
2742
非洲、南美洲的人們,
08:25
they told us that they could use it too,
170
505377
1911
他們告訴我們, 他們也可以運用這個方法;
08:27
and what's most important,
171
507288
1280
而最重要的是,
08:28
what we'd found that we thought might be exceptional,
172
508568
2498
我們之前發現了不起的是
08:31
in the forest there was pretty good cell phone service.
173
511066
2582
雨林的手機服務相當不錯,
08:33
That was not exceptional, we were told,
174
513648
1877
人們告訴我們,那不是了不起,
08:35
and that particularly is on the periphery of the forests that are most under threat.
175
515525
3943
特別是在森林的邊陲地帶、 最深受威脅的地區。
08:39
And then something really amazing happened,
176
519468
2300
接著真正令人驚喜的東西發生了,
08:41
which was that people started sending us their own old cell phones.
177
521768
3483
人們開始寄給我們舊手機;
08:45
So in fact what we have now is a system
178
525251
1950
我們現在擁有一個系統,
08:47
where we can use people on the ground, people who are already there,
179
527201
3343
我們可以運用普羅大眾、四周的居民,
08:50
who can both improve and use the existing connectivity,
180
530544
3065
他們可以同時改善、 使用現有的網絡,
08:53
and we're using old cell phones that are being sent to us
181
533609
2677
並且我們利用 世界各地人們寄過來的舊手機,
08:56
by people from around the world
182
536286
1493
並且我們利用 世界各地人們寄過來的舊手機,
08:57
that want their phones to be doing something else in their afterlife,
183
537779
3293
他們希望舊手機 可以在丟棄後發揮功效,
或許可以這麼說。
09:01
so to speak.
184
541072
754
09:01
And if the rest of the device can be completely recycled,
185
541826
2929
假若剩餘的手機也可以完全作回收,
我們相信 那會是全然升級改造的手機。
09:04
then we believe it's an entirely upcycled device.
186
544755
2716
09:07
So again, this didn't come because of any sort of high-tech solution.
187
547471
3654
再次重申,這個項目的成功 不是因為任何高科技解決方案,
09:11
It just came from using what's already there,
188
551125
2313
這僅是就地取材,
09:13
and I'm thoroughly convinced that if it's not phones,
189
553438
2856
而我完全相信如果不是用手機,
09:16
that there's always going to be enough there
190
556294
2369
當地總會有足夠的東西
09:18
that you can build similar solutions
191
558663
1811
可以建構相似的解決方案,
09:20
that can be very effective in new contexts.
192
560474
2066
在新的環境中起到很好的作用。
09:22
Thank you very much.
193
562540
2136
謝謝!
(掌聲)
09:24
