In the summer of 2011,
as a tourist,
as a tourist,
1
9680
3487
2011年夏天，
我以旅行者的身份，
我以旅行者的身份，
00:25
I visited the rainforests of Borneo
for the very first time,
for the very first time,
2
13167
4426
第一次拜訪婆羅洲的雨林。
00:29
and as you might imagine,
3
17593
2048
你也許猜想到，
00:31
it was the overwhelming sounds
of the forest that struck me the most.
of the forest that struck me the most.
4
19641
5270
我印象最深刻的，
是鋪天蓋地的雨林之聲。
是鋪天蓋地的雨林之聲。
00:36
There's this constant cacophony of noise.
5
24911
2810
有一個持續不斷的雜音。
00:39
Some things actually do stick out.
6
27721
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.
a rhinoceros hornbill.
7
30136
4426
例如，這有一隻大鳥，
是一隻犀鳥
是一隻犀鳥
00:46
This buzzing is a cicada.
8
34562
4172
這是蟬的鳴叫聲；
00:51
This is a family of gibbons.
9
39434
2613
這是一個長臂猿家族，
00:54
It's actually singing to each other
over a great distance.
over a great distance.
10
42047
4114
牠正向遠處的家人歌唱。
據記載，這地方
是一個長臂猿的保護區，
是一個長臂猿的保護區，
00:59
The place where this was recorded
was in fact a gibbon reserve,
was in fact a gibbon reserve,
11
47341
2993
01:02
which is why you can hear so many of them,
12
50334
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
was coming out of the forest that time
13
52372
4930
但那時森林中最重要的聲音
01:09
was one that I didn't notice,
14
57302
1532
卻是我當時沒注意的聲音，
01:10
and in fact nobody there
had actually noticed it.
had actually noticed it.
15
58834
3109
事實上那裡沒有人
真的注意到那個聲音。
真的注意到那個聲音。
01:14
So, as I said, this was a gibbon reserve.
16
62373
1988
如我所說，這是長臂猿保護區。
01:16
They spend most of their time
rehabilitating gibbons,
rehabilitating gibbons,
17
64361
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
to spend a lot of their time
18
67170
2561
也花了大量時間
01:21
protecting their area from illegal logging
that takes place on the side.
that takes place on the side.
19
69731
3692
保護長臂猿的生長區域
不受邊境非法盜木所影響。
不受邊境非法盜木所影響。
01:25
And so if we take the sound of the forest
20
73423
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,
the insects, and the rest,
21
75466
3557
調降長臂猿、昆蟲
以及其他動物的聲音，
以及其他動物的聲音，
01:31
in the background, the entire time,
in recordings you heard,
in recordings you heard,
22
79023
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.
at great distance.
23
82689
3714
來自遠處的電鋸聲。
01:38
They had three full-time guards
who were posted around this sanctuary
who were posted around this sanctuary
24
86403
3994
當地有三位全職警衛
戍守這個避護所，
戍守這個避護所，
01:42
whose job was in fact
to guard against illegal logging,
to guard against illegal logging,
25
90397
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,
again as tourists, out into the forest,
26
94599
3459
而某天，
我們再次以旅者的身份走入雨林，
我們再次以旅者的身份走入雨林，
01:50
and within five minutes' walk,
27
98058
2253
5分鐘後，
01:52
we stumbled upon somebody
who was just sawing a tree down,
who was just sawing a tree down,
28
100311
3379
我們看見了
有人剛剛把一顆樹鋸下來。
有人剛剛把一顆樹鋸下來。
01:55
five minutes' walk, a few hundred meters
from the ranger station.
from the ranger station.
29
103690
3261
就在5分鐘路程內，
離警衛駐點數百公尺之外。
離警衛駐點數百公尺之外。
01:58
They hadn't been able
to hear the chainsaws,
to hear the chainsaws,
30
106951
2058
他們從未聽到電鋸聲，
02:01
because as you heard,
the forest is very, very loud.
the forest is very, very loud.
31
109009
3817
因為如你所聽，
森林聲音非常、非常大。
森林聲音非常、非常大。
02:04
It struck me as quite unacceptable
that in this modern time,
that in this modern time,
32
112826
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,
from a ranger station in a sanctuary,
33
116745
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.
someone who has a chainsaw gets fired up.
34
121217
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.
but in fact, it was quite true.
35
125022
4665
這聽來不可思議，
但事實上，這是十分真確的。
但事實上，這是十分真確的。
02:21
So how do we stop illegal logging?
36
129689
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,
always to come up with a high-tech,
37
131523
3429
這真令人技癢，
工程師總想要高科技，
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
134952
1761
02:28
but in fact, you're in the rainforest.
39
136713
1950
但事實上，你身處雨林，
02:30
It has to be simple,
it has to be scalable,
it has to be scalable,
40
138663
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
while were there was that
41
141040
3008
而我們注意到
02:36
everything we needed was already there.
42
144048
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
that would allow us to stop this
43
146374
2751
我們可以構架一個系統，
02:41
using what's already there.
44
149125
2282
就地取材阻止盜伐。
02:43
Who was there? What was
already in the forest?
already in the forest?
45
151407
2232
誰在那？森林裡有什麼？
02:45
Well, we had people.
46
153639
1148
我們有人手，
02:46
We had this group there that was
dedicated, three full-time guards,
dedicated, three full-time guards,
47
154787
3285
我們有3位全職警衛，
02:50
that was dedicated to go and stop it,
48
158072
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.
what was happening out in the forest.
49
159846
3114
而他們需要的是
知道森林裡發生了什麼事。
知道森林裡發生了什麼事。
02:54
The real surprise, this is the big one,
50
162960
1893
令人驚訝，超乎預期的是，
02:56
was that there was connectivity
out in the forest.
out in the forest.
51
164853
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.
way out in the middle of nowhere.
52
167236
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,
from the nearest road,
53
170150
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,
but they had very good cell phone service,
54
173081
3572
當然沒有電力，
但卻有很好的手機訊號，
但卻有很好的手機訊號，
03:08
these people in the towns
were on Facebook all the time,
were on Facebook all the time,
55
176653
2623
城鎮中的人們
總是掛在Facebook，
總是掛在Facebook，
用他們的手機瀏覽網路，
03:11
they're surfing the web on their phones,
56
179276
1950
03:13
and this sort of got me thinking
that in fact it would be possible
that in fact it would be possible
57
181226
3109
而這讓我想到也許可以
03:16
to use the sounds of the forest,
58
184335
2159
利用森林裡的聲音，
03:18
pick up the sounds
of chainsaws programmatically,
of chainsaws programmatically,
59
186494
2392
用程序擷取電鋸的音頻，
03:20
because people can't hear them,
60
188886
1648
因為人們無法聽到，
03:22
and send an alert.
61
190534
1687
並送出警示。
03:24
But you have to have a device
to go up in the trees.
to go up in the trees.
62
192221
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,
to listen to the sounds of the forest,
63
194803
3651
如果我們可以運用某些設備
來聽取森林的聲音，
來聽取森林的聲音，
03:30
connect to the cell phone
network that's there,
network that's there,
64
198454
2233
連結到手機的網絡，
03:32
and send an alert to people on the ground,
65
200687
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.
to this issue for them.
66
202721
3550
或許，我們可以
為他們找到解決方案。
為他們找到解決方案。
03:38
But let's take a moment
to talk about saving the rainforest,
to talk about saving the rainforest,
67
206271
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.
definitely all heard about forever.
68
209551
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
have heard about saving the rainforest
69
213393
2919
與我同輩的人都聽過拯救雨林，
03:48
since we were kids,
70
216312
1900
從我們還是孩子的時候，
03:50
and it seems that the message
has never changed:
has never changed:
71
218212
2248
而這似乎未曾改變，
03:52
We've got to save the rainforest,
it's super urgent,
it's super urgent,
72
220460
2522
我們要拯救雨林，這超級迫切，
03:54
this many football fields
have been destroyed yesterday.
have been destroyed yesterday.
73
222982
2706
如此多足球場般大的雨林
昨日已被摧毀。
昨日已被摧毀。
03:57
and yet here we are today,
about half of the rainforest remains,
about half of the rainforest remains,
74
225688
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.
problems like climate change.
75
228992
4327
我們已有潛在更迫切的問題，
例如氣候變遷。
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:
that I didn't realize at the time:
76
233319
3909
但，有一些少為人知的事實
我當時並不知道
我當時並不知道
04:09
Deforestation accounts

for more greenhouse gas

237228

78
240189
4040
比全世界的飛機、火車、汽車、
卡車、船運加總還要多，
卡車、船運加總還要多，
04:16
It's the second highest contributor
to climate change.
to climate change.
79
244229
2716
是造成氣候變遷的第二大起因。
04:18
Also, according to Interpol,
80
246945
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
that takes place in the rainforest
81
249778
3529
雨林區的伐木有高達90%
04:25
is illegal logging,
like the illegal logging that we saw.
like the illegal logging that we saw.
82
253307
3781
都是違法的，
就像我們所看到的盜伐。
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,
enforce the rules that are there,
83
257088
4044
若我們能幫助雨林的人們
執行當地的法律，
執行當地的法律，
04:33
then in fact we could eat heavily
into this 17 percent
into this 17 percent
84
261132
3924
我們可以減少
高達17%的溫室氣體，
高達17%的溫室氣體，
04:37
and potentially have a major impact
in the short term.
in the short term.
85
265056
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.
fastest way to fight climate change.
86
267667
5165
這也許是擊退氣候變遷
最便宜、最快速的方法。
最便宜、最快速的方法。
04:44
And so here's the system that we imagine.
87
272832
1998
這是我們構想的系統，
04:46
It looks super high tech.
88
274830
1194
看起來像超高端科技。
04:48
The moment a sound of a chainsaw
is heard in the forest,
is heard in the forest,
89
276024
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,
of the chainsaw,
90
278657
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
GSM network that's already there
91
280829
3607
透過現有的標準GSM網絡
發出警示
發出警示
04:56
to a ranger in the field
92
284436
2087
給當地的警衛，
04:58
who can in fact show up in real time
and stop the logging.
and stop the logging.
93
286523
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.
and finding a tree that's been cut.
94
289340
3909
這不需要走到外面，
才發現樹木被砍了。
才發現樹木被砍了。
05:05
It's not about seeing
a tree from a satellite
a tree from a satellite
95
293249
2176
也不必看區域衛星圖
05:07
in an area that's been clear cut,
96
295425
1636
看有沒有樹被砍倒，
05:09
it's about real-time intervention.
97
297061
2198
這是即時的干預。
05:11
So I said it was the cheapest
and fastest way to do it,
and fastest way to do it,
98
299669
2721
如我所說，
這是最便宜、最快速的方法，
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,
they weren't able to do it,
99
302390
2925
但事實上，如你所見，
他們無法做到，
他們無法做到，
05:17
so it may not be so cheap and fast.
100
305315
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,
were actually cell phones,
101
307199
3436
但如果樹上的設備是手機的話，
05:22
it could be pretty cheap.
102
310635
1556
那可以是非常便宜的。
05:24
Cell phones are thrown away
by the hundreds of millions every year,
by the hundreds of millions every year,
103
312191
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
316478
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,
which of course we should do,
105
318599
3181
這還沒算到世界其他地區，
當然我們應該算到；
當然我們應該算到；
05:33
but in fact, cell phones are great.
106
321780
2531
但事實上，手機是很棒的！
05:36
They're full of sensors.
107
324311
1333
手機充滿感測器
05:37
They can listen
to the sounds of the forest.
to the sounds of the forest.
108
325644
2152
可以聽取森林的聲音；
05:39
We do have to protect them.
109
327796
1382
我們需要保護手機，
05:41
We have to put them in this box
that you see here,
that you see here,
110
329178
2407
我們需要把手機放在盒子裡，
如你在此所見。
如你在此所見。
05:43
and we do have to power them.
111
331585
1567
我們需要替手機充電，
05:45
Powering them is one of the greater
engineering challenges
engineering challenges
112
333152
2763
替手機充電一項重大工程挑戰，
05:47
that we had to deal with,
113
335915
1300
我們必須面對，
05:49
because powering a cell phone
under a tree canopy,
under a tree canopy,
114
337215
2752
因為在樹蔭下替手機充電，
05:51
any sort of solar power
under a tree canopy,
under a tree canopy,
115
339967
2252
任何在樹蔭下的太陽能，
05:54
was an as-yet-unsolved problem,
116
342219
1810
都尚未做到；
05:56
and that's this unique
solar panel design that you see here,
solar panel design that you see here,
117
344029
2857
而這就是獨一無二的
太陽能面板設計，
太陽能面板設計，
05:58
which in fact is built also from recycled
byproducts of an industrial process.
byproducts of an industrial process.
118
346886
4319
這是由工廠製程中
回收的副產品所組成的，
回收的副產品所組成的，
06:03
These are strips that are cut down.
119
351205
2624
這些是剩下的腳料。
06:05
So this is me putting it all together
120
353829
3506
這是我，
正將所有東西組裝在一起，
正將所有東西組裝在一起，
06:09
in my parents' garage, actually.
121
357335
1881
在我父母的車庫中，
06:11
Thanks very much to them
for allowing me to do that.
for allowing me to do that.
122
359216
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.
this is a device up in a tree.
123
361793
4356
如你所見，
這套設備在樹上的樣子。
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
is that they are pretty well obscured
124
366149
3585
如你所見，樹上的這些設備，
06:21
up in the tree canopy at a distance.
125
369734
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
they are able to hear chainsaw noises
126
371536
3477
那很重要，雖然它們可以聽到
06:27
up to a kilometer in the distance,
127
375013
1770
遠至一公里之外的電鋸聲，
06:28
allowing them to cover
about three square kilometers,
about three square kilometers,
128
376783
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.
it would make the area unprotected.
129
379303
3178
但如果有人把它拿走，
這個區域就不受保護了。
這個區域就不受保護了。
06:35
So does it actually work?
130
383281
2753
這真的行得通嗎？
06:38
Well, to test it,
we took it back to Indonesia,
we took it back to Indonesia,
131
386034
2972
嗯，來試試看，
我們帶著它回到印尼，
我們帶著它回到印尼，
06:41
not the same place, but another place,
132
389006
2113
不是同個地方，而是另一個地方，
06:43
to another gibbon reserve
133
391119
1671
去到另一個長臂猿保護區，
06:44
that was threatened daily
by illegal logging.
by illegal logging.
134
392790
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.
illegal chainsaw noises.
135
396505
3919
就在第二天，
它擷取到非法的電鋸聲，
它擷取到非法的電鋸聲，
06:52
We were able to get a real-time alert.
136
400424
2199
我們能夠得到一個即時的警示，
06:54
I got an email on my phone.
137
402623
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.
Everyone had just gotten back down.
138
403970
3716
事實上，我們剛爬完樹，
大家才剛回到地面，
大家才剛回到地面，
06:59
All these guys are smoking cigarettes,
139
407686
2240
大夥正在抽煙，
07:01
and then I get an email,
and they all quiet down,
and they all quiet down,
140
409926
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
412783
2104
事實上你可以聽到電鋸聲，
07:06
really, really faint in the background,
142
414887
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.
until that moment.
143
416816
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.
to actually stop these loggers.
144
419121
3274
接著，我們動身前去阻止伐木者；
07:14
I was pretty nervous.
145
422395
1509
我十分緊張，
07:15
This is the moment where we've actually
arrived close to where the loggers are.
arrived close to where the loggers are.
146
423904
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
where I'm actually regretting
147
428130
3114
這時我也許之前的所有努力
開始感到後悔，
開始感到後悔，
07:23
perhaps the entire endeavor.
148
431244
2001
這時我也許對之前所有的努力
開始感到後悔，
開始感到後悔，
07:25
I'm not really sure what's on
the other side of this hill.
the other side of this hill.
149
433245
2743
我不確定山坡另一邊的狀況。
07:27
That guy's much braver than I am.
150
435988
1963
那位老兄比我勇敢得多，
07:29
But he went, so I had to go, walking up,
151
437951
4180
但他去了，所以我必須去，
07:34
and in fact, he made it over the hill,
152
442131
2159
他登上山坡，
07:36
and interrupted the loggers in the act.
153
444290
3237
中斷伐木者的行動。
07:39
For them, it was such a surprise --
154
447527
1662
對他們而言，這非常令人驚訝---
07:41
they had never, ever
been interrupted before --
been interrupted before --
155
449189
2380
他們之前從來沒有被中斷過---
07:43
that it was such an impressive
event for them,
event for them,
156
451569
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.
they have not been back since.
157
453734
3116
後來夥伴們告訴我們，
自此之後他們再也沒來。
自此之後他們再也沒來。
07:48
They were, in fact, great guys.
158
456850
1492
他們真的是很棒的人！
07:50
They showed us how
the entire operation works,
the entire operation works,
159
458342
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
on the spot was that
160
460522
2574
他們當場使我們相信：
07:55
if you can show up
in real time and stop people,
in real time and stop people,
161
463096
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.
they won't come back.
162
465341
4182
那會有很足夠的嚇阻作用
讓他們不再回來。
讓他們不再回來。
08:01
So --
163
469529
1556
所以
08:03
Thank you. (Applause)
164
471085
4991
謝謝 (掌聲)
08:09
Word of this spread, possibly
because we told a lot of people,
because we told a lot of people,
165
477586
3854
這件事情廣泛流傳了，
也許是因為我們跟很多人說過了，
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.
amazing stuff started to happen.
166
481440
3437
而事實上，
後來有些令人驚喜的東西開始發生。
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.
started to send us emails, phone calls.
167
484877
3669
世界各地的人們
開始寄郵件和手機給我們，
開始寄郵件和手機給我們，
08:20
What we saw was that people
throughout Asia,
throughout Asia,
168
488546
2089
我們看到來自亞洲、
08:22
people throughout Africa,
people throughout South America,
people throughout South America,
169
490635
2742
非洲、南美洲的人們，
08:25
they told us that they could use it too,
170
493377
1911
他們告訴我們，
他們也可以運用這個方法；
他們也可以運用這個方法；
08:27
and what's most important,
171
495288
1280
而最重要的是，
08:28
what we'd found that
we thought might be exceptional,
we thought might be exceptional,
172
496568
2498
我們之前發現了不起的是
08:31
in the forest there was
pretty good cell phone service.
pretty good cell phone service.
173
499066
2582
雨林的手機服務相當不錯，
08:33
That was not exceptional, we were told,
174
501648
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.
of the forests that are most under threat.
175
503525
3943
特別是在森林的邊陲地帶、
最深受威脅的地區。
最深受威脅的地區。
08:39
And then something
really amazing happened,
really amazing happened,
176
507468
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.
their own old cell phones.
177
509768
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
513251
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,
people who are already there,
179
515201
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,
and use the existing connectivity,
180
518544
3065
他們可以同時改善、
使用現有的網絡，
使用現有的網絡，
08:53
and we're using old cell phones
that are being sent to us
that are being sent to us
181
521609
2677
並且我們利用
世界各地人們寄過來的舊手機，
世界各地人們寄過來的舊手機，
08:56
by people from around the world
182
524286
1493
並且我們利用
世界各地人們寄過來的舊手機，
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,
something else in their afterlife,
183
525779
3293
他們希望舊手機
可以在丟棄後發揮功效，
可以在丟棄後發揮功效，
或許可以這麼說。
09:01
so to speak.
184
529072
754
假若剩餘的手機也可以完全作回收，
09:01
And if the rest of the device
can be completely recycled,
can be completely recycled,
185
529826
2929
我們相信
那會是全然升級改造的手機。
那會是全然升級改造的手機。
09:04
then we believe it's
an entirely upcycled device.
an entirely upcycled device.
186
532755
2716
09:07
So again, this didn't come
because of any sort of high-tech solution.
because of any sort of high-tech solution.
187
535471
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，
不是因為任何高科技解決方案，
09:11
It just came from using
what's already there,
what's already there,
188
539125
2313
這僅是就地取材，
09:13
and I'm thoroughly convinced
that if it's not phones,
that if it's not phones,
189
541438
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
going to be enough there
190
544294
2369
當地總會有足夠的東西
09:18
that you can build similar solutions
191
546663
1811
可以建構相似的解決方案，
09:20
that can be very effective
in new contexts.
in new contexts.
192
548474
2066
在新的環境中起到很好的作用。
09:22
Thank you very much.
193
550540
2136
謝謝！

ABOUT THE SPEAKER
Topher White - Conservation technologistThrough his startup Rainforest Connection, Topher White transforms used cell phones into guardians of the rainforest.
Why you should listen
In 2012, Topher White founded Rainforest Connection, a startup which converts recycled cell-phones into solar-powered listening devices to monitor and protect remote areas of the rainforest. Now an established NGO, Rainforest Connection has helped stop illegal logging and poaching operations in Sumatra, and the system is being expanded to three more rainforest reserves in Indonesia, the Amazon and Africa.
With a background in physics and engineering, White worked as web chief of ITER and co-founded Enthuse, a sports engagement and mobile rewards platform. For Rainforest Connection, he’s fashioned a simple device made of discarded cell phones and solar panels that detects and sends alerts when it picks up the sound of chainsaws in protected rainforests, allowing for intervention in real time.
