The job of uncovering the global food waste scandal
0

2758
我在15歲時就開始揭穿
00:19
started for me when I was 15 years old.
1
3717
3018
全球浪費食物的醜行
00:22
I bought some pigs. I was living in Sussex.
2
6735
2521
我買了幾頭豬，當時我住在英格蘭薩西克斯郡
00:25
And I started to feed them in the most traditional
3
9256
2383
而我用最傳統
00:27
and environmentally friendly way.
4
11639
1971
最環保的方式飼養牠們
00:29
I went to my school kitchen, and I said,
5
13610
2325
我去我們學校的廚房跟他們說：
00:31
"Give me the scraps that my school friends have turned
6
15935
1546
「給我一些同學們不屑吃的
00:33
their noses up at."
7
17481
866
連聞都不想聞的廚餘吧。」
00:34
I went to the local baker and took their stale bread.
8
18347
2664
我去附近的麵包店拿不新鮮的麵包
00:36
I went to the local greengrocer, and I went to a farmer
9
21011
2732
我去蔬果攤，我去找農夫
00:39
who was throwing away potatoes because they were
10
23743
1838
去拿他們要丟掉的馬鈴薯，因為這些馬鈴薯
00:41
the wrong shape or size for supermarkets.
11
25581
3186
不符合超市收購所要求的形狀或尺寸
00:44
This was great. My pigs turned that food waste
12
28767
3089
這方法棒極了。我的豬把那些本來會浪費掉的食物
00:47
into delicious pork. I sold that pork
13
31856
2657
轉變成好吃的豬肉。我把這些豬肉
00:50
to my school friends' parents, and I made
14
34513
1987
賣給同學的父母，而我因此
00:52
a good pocket money addition to my teenage allowance.
15
36500
4637
賺了一筆為數不錯的零用錢，口袋豐滿了不少
00:57
But I noticed that most of the food that I was giving my pigs
16
41137
2882
但我注意到我給豬吃的大多數食物
00:59
was in fact fit for human consumption,
17
44019
2383
事實上都還可以給人吃
01:02
and that I was only scratching the surface,
18
46402
2269
我還注意到我只是看到事實的表面
01:04
and that right the way up the food supply chain,
19
48671
2862
也注意到整條食物供給鏈
01:07
in supermarkets, greengrocers, bakers, in our homes,
20
51533
3218
從超市、蔬果攤、麵包店、我們的家
01:10
in factories and farms, we were hemorrhaging out food.
21
54751
3260
到工廠及農場，我們簡直是食物大出血
01:13
Supermarkets didn't even want to talk to me
22
58011
2597
超市根本就不想跟我談
01:16
about how much food they were wasting.
23
60608
1374
他們到底浪費了多少食物
01:17
I'd been round the back. I'd seen bins full of food
24
61982
2484
我曾繞到店家的後面，看著一桶又一桶滿滿的食物
01:20
being locked and then trucked off to landfill sites,
25
64466
2751
被鎖在那裡，然後被垃圾車載到掩埋場
01:23
and I thought, surely there is something more sensible
26
67217
3021
所以我想，應該還有更合理的方法
01:26
to do with food than waste it.
27
70238
3167
可以處理這些食物，而不是扔掉
01:29
One morning, when I was feeding my pigs,
28
73405
2305
有一天早上，我在餵豬的時候
01:31
I noticed a particularly tasty-looking sun-dried tomato loaf
29
75710
3687
注意到有一片看起來很好吃的蕃茄乾土司
01:35
that used to crop up from time to time.
30
79397
2075
這樣的土司偶爾會出現在廚餘裡
01:37
I grabbed hold of it,
31
81472
1402
我趕快把它撿起來
01:38
sat down, and ate my breakfast with my pigs. (Laughter)
32
82874
3546
坐下，與我的豬共進早餐（笑聲）
01:42
That was the first act of what I later learned to call freeganism,
33
86420
3120
這是我第一次實踐不消費主義（freeganism）
這是我後來學到的名詞
這是我後來學到的名詞
01:45
really an exhibition of the injustice of food waste,
34
89540
4255
這顯示了我們如何錯待廚餘
01:49
and the provision of the solution to food waste,
35
93795
2350
同時也爲如何處理廚餘提供解答
01:52
which is simply to sit down and eat food,
36
96145
2654
其實就是坐下來吃掉這些食物
01:54
rather than throwing it away.
37
98799
1488
不要把它丟掉
01:56
That became, as it were, a way of confronting
38
100287
3279
這真的變成要面對面挑戰
01:59
large businesses in the business of wasting food,
39
103566
2987
那些浪費食物的大型企業
02:02
and exposing, most importantly, to the public,
40
106553
2521
更重要的，是對大眾揭露
02:04
that when we're talking about food being thrown away,
41
109074
2170
當我們談論被丟棄的食物
02:07
we're not talking about rotten stuff, we're not talking about
42
111244
2139
我們不是在說壞掉的食物，我們不是在說
02:09
stuff that's beyond the pale.
43
113383
2712
那些超過保存期限的東西
02:11
We're talking about good, fresh food that is being wasted
44
116095
2116
我們是在談那些還很好還很新鮮的食物
02:14
on a colossal scale.
45
118211
2538
就這樣被大量的浪費掉
02:16
Eventually, I set about writing my book,
46
120749
1857
我後來終於決定寫書
02:18
really to demonstrate the extent of this problem
47
122606
2054
來告訴大家這個問題的嚴重程度
02:20
on a global scale. What this shows is
48
124660
3396
已經到了全球化的規模。這裡顯示的是
02:23
a nation-by-nation breakdown of the likely level
49
128056
3479
以國家來細分，這世上每一個國家
02:27
of food waste in each country in the world.
50
131535
3102
浪費食物的可能程度
02:30
Unfortunately, empirical data, good, hard stats, don't exist,
51
134637
3888
不幸的是，實證數據，那些很好很紮實的統計數據並不存在
02:34
and therefore to prove my point, I first of all had to find
52
138525
2482
所以為了證明我的觀點，我首先必須找出
02:36
some proxy way of uncovering
53
141007
2153
一些能夠揭露
02:39
how much food was being wasted.
54
143160
2245
有多少食物已經被浪費掉的替代方法
02:41
So I took the food supply of every single country
55
145405
2556
所以我把每一個國家的食物供給量
02:43
and I compared it to what was actually likely
56
147961
3042
與那個國家的實際食物消費量
02:46
to be being consumed in each country.
57
151003
2032
拿來作比較
02:48
That's based on diet intake surveys, it's based on
58
153035
3887
這數據是以調查飲食攝入量及肥胖程度為基本
02:52
levels of obesity, it's based on a range of factors
59
156922
2666
以及一系列讓你能粗略地估算
02:55
that gives you an approximate guess
60
159588
1342
到底有多少食物
02:56
as to how much food is actually going into people's mouths.
61
160930
3227
真的被吃掉的因素為基準所得到的結果
03:00
That black line in the middle of that table
62
164157
2729
那條在圖中間的黑線
03:02
is the likely level of consumption
63
166886
2996
是大概能吃掉多少的量
03:05
with an allowance for certain levels of inevitable waste.
64
169882
4362
其中已經加了一些不可避免的浪費量
03:10
There will always be waste. I'm not that unrealistic
65
174244
1919
總是會有浪費，我沒有那麼不實際
03:12
that I think we can live in a waste-free world.
66
176163
1980
認為我們可以活在完全沒有浪費的世界
03:14
But that black line shows what a food supply should be
67
178143
3873
所以那條黑線顯示了一個國家的食物供給量
03:17
in a country if they allow for a good, stable, secure,
68
182016
4454
應該是多少，假設他們能提供良好、穩定又安全的
03:22
nutritional diet for every person in that country.
69
186470
3749
營養食物給國家裡的每一個人
03:26
Any dot above that line, and you'll quickly notice that
70
190219
2407
所以超過這條線的點，你很快就會注意到
03:28
that includes most countries in the world,
71
192626
2701
這世上大多數的國家都在此線之上
03:31
represents unnecessary surplus, and is likely to reflect
72
195327
4289
這代表著不必要的糧食過剩，而且大致能反映
03:35
levels of waste in each country.
73
199616
2622
每一個國家的浪費程度
03:38
As a country gets richer, it invests more and more
74
202238
3269
當國家變得更富有，商店及餐廳的
03:41
in getting more and more surplus
75
205507
1291
食物過剩現象
03:42
into its shops and restaurants,
76
206798
2810
也愈來愈明顯
03:45
and as you can see, most European
77
209608
2056
正如你所見，大部分的歐洲
03:47
and North American countries
78
211664
1412
及北美洲國家
03:48
fall between 150 and 200 percent
79
213076
3140
都落在人口營養需求量的
03:52
of the nutritional requirements of their populations.
80
216216
3380
百分之一百五到二百之間
03:55
So a country like America has twice as much food
81
219596
2408
意思是像美國這樣的國家，有超過兩倍以上
03:57
on its shop shelves and in its restaurants
82
222004
2604
美國人實際所需的食物
04:00
than is actually required to feed the American people.
83
224608
3568
擺在店架及餐廳裡
04:04
But the thing that really struck me,
84
228176
1560
但是真正讓我震驚的是
04:05
when I plotted all this data, and it was a lot of numbers,
85
229736
4215
當我把這些資料畫成圖時，這是很大一批數據
04:09
was that you can see how it levels off.
86
233951
3666
你可以看到它趨緩的走勢
04:13
Countries rapidly shoot towards that 150 mark,
87
237617
3068
這些國家迅速達到150這個點
04:16
and then they level off, and they don't really go on rising
88
240685
3288
然後持平，不再完全如你所預期的
04:19
as you might expect.
89
243973
1546
繼續上升
04:21
So I decided to unpack that data a little bit further
90
245519
2545
所以我決定進一步研究這些數據
04:23
to see if that was true or false.
91
248064
2285
看看到底這種走勢是反應事實還是假象
04:26
And that's what I came up with.
92
250349
1494
而這是我得到的結果
04:27
If you include not just the food that ends up
93
251843
1927
如果你把商店及餐廳的食物
04:29
in shops and restaurants, but also the food
94
253770
2124
以及人們拿去餵牲畜的食物
04:31
that people feed to livestock,
95
255894
2156
都包括在裡面
04:33
the maize, the soy, the wheat, that humans could eat
96
258050
3503
也就是你把玉米、黃豆、麥子
這些本來是人類可以吃的食物
這些本來是人類可以吃的食物
04:37
but choose to fatten livestock instead to produce
97
261553
2481
拿去養肥牲畜以生產
04:39
increasing amounts of meat and dairy products,
98
264034
1931
更多量的肉品及奶製品
04:41
what you find is that most rich countries
99
265965
1667
那麼你會發現大部分的富裕國家
04:43
have between three and four times the amount of food
100
267632
4323
有三到四倍那麼多
04:47
that their population needs to feed itself.
101
271955
3084
餵飽他們的人口所需的食物
04:50
A country like America has four times the amount of food
102
275039
3283
而像美國這個國家有著它所需
04:54
that it needs.
103
278322
2962
四倍的食物
04:57
When people talk about the need to increase global
104
281284
2962
當大家在討論是否需要增加全球
05:00
food production to feed those nine billion people
105
284246
2660
糧食生產以餵飽預計到2050年
05:02
that are expected on the planet by 2050,
106
286906
2512
會增長到九十億的全球人口
05:05
I always think of these graphs.
107
289418
1721
我總是想到我的這些圖表
05:07
The fact is, we have an enormous buffer
108
291139
2951
事實上，在富裕的國家
05:09
in rich countries between ourselves and hunger.
109
294090
3881
我們有足以因應飢荒的食物
05:13
We've never had such gargantuan surpluses before.
110
297971
4676
這麼龐大數量的多餘糧食是前所未見的
05:18
In many ways, this is a great success story
111
302647
2666
從很多角度來看這是個成功的人類文明發展故事
05:21
of human civilization, of the agricultural surpluses
112
305313
4139
是個在一萬兩千年前人類就想要達到的
05:25
that we set out to achieve 12,000 years ago.
113
309452
3353
農業盈餘目標
05:28
It is a success story. It has been a success story.
114
312805
3557
這是個成功的故事，一直以來都是
05:32
But what we have to recognize now is that we are
115
316362
2537
但是現在我們必須承認，我們
05:34
reaching the ecological limits that our planet can bear,
116
318899
3632
正朝著地球所能容忍的生態發展限制邁進
05:38
and when we chop down forests, as we are every day,
117
322531
2637
當我們砍下森林來種植更多的糧食
05:41
to grow more and more food,
118
325168
1348
現在我們每天都這麼做
05:42
when we extract water from depleting water reserves,
119
326516
3748
當我們從日漸乾涸的水庫取水
05:46
when we emit fossil fuel emissions in the quest
120
330264
3388
當我們排放石化燃料廢氣以尋求
05:49
to grow more and more food,
121
333652
1292
能種植更多的糧食的同時
05:50
and then we throw away so much of it,
122
334944
2851
我們卻丟掉這麼多的糧食
05:53
we have to think about what we can start saving.
123
337795
2936
我們必須思考該如何開始節約糧食
05:56
And yesterday, I went to one of the local supermarkets
124
340731
3725
昨天我去一家附近的超市
06:00
that I often visit to
125
344456
2216
我常常去那裡查看 --
06:02
inspect, if you like, what they're throwing away.
126
346672
4181
你可以這麼說 -- 他們丟了哪些食物
06:06
I found quite a few packets of biscuits amongst
127
350853
2403
我找到了好幾包餅乾，混在
06:09
all the fruit and vegetables and everything else
128
353256
1627
那些被丟棄的水果蔬菜
06:10
that was in there.
129
354883
947
及其他的東西裡
06:11
And I thought, well this could serve as a symbol for today.
130
355830
2440
我就在想，嗯，這可以當我今天的教材
06:14
So I want you to imagine that these nine biscuits
131
358270
2435
所以我現在要你想像一下這九片
06:16
that I found in the bin represent the global food supply,
132
360705
3528
我在垃圾桶裡找到的餅乾，代表着全球糧食供給
06:20
okay? We start out with nine.
133
364233
1601
可以嗎？我們從九片開始
06:21
That's what's in fields around the world every single year.
134
365834
3483
這代表全球的全年作物種植量
06:25
The first biscuit we're going to lose
135
369317
1761
在作物還沒離開農場出貨前
06:26
before we even leave the farm.
136
371078
1759
我們就要先拿掉一片餅乾
06:28
That's a problem primarily associated with
137
372837
3265
這問題的主因與
06:32
developing work agriculture, whether it's
138
376102
1664
農工發展有關。可能是因為
06:33
a lack of infrastructure, refrigeration, pasteurization,
139
377766
2505
缺乏基礎設施，沒有冰箱，沒有殺菌設備
06:36
grain stores, even basic fruit crates, which means
140
380271
2913
穀物保存不當，甚至是缺乏最基本的水果箱
06:39
that food goes to waste before it even leaves the fields.
141
383184
3749
所以這部分的作物在從農場出貨前就已經浪費掉了
06:42
The next three biscuits are the foods that we decide
142
386933
3496
接下來的三片餅乾代表著那些我們決定
06:46
to feed to livestock, the maize, the wheat and the soya.
143
390429
3740
拿來餵牲畜的糧食，玉米、麥子、黃豆
06:50
Unfortunately, our beasts are inefficient animals,
144
394169
4844
不幸的是這些牲畜是效率很低的動物
06:54
and they turn two-thirds of that into feces and heat,
145
399013
4175
牠們把三分之二的糧食轉成糞便及熱能
06:59
so we've lost those two, and we've only kept this one
146
403188
2618
所以我們要拿掉兩片，只留下一片在這
07:01
in meat and dairy products.
147
405806
2234
代表着肉品及乳製品
07:03
Two more we're going to throw away directly into bins.
148
408040
3584
接下來我們要直接丟掉兩片到垃圾桶裡
07:07
This is what most of us think of when we think
149
411624
1553
這就是我們所認知的
07:09
of food waste, what ends up in the garbage,
150

糧食浪費，即那些被丟到垃圾桶裡的
07:11
what ends up in supermarket bins,
151
415688
1848
那些被超市丟棄的
07:13
what ends up in restaurant bins. We've lost another two,
152
417536
2730
還有那些被餐廳丟棄的食物，我們為此丟掉兩片餅乾
07:16
and we've left ourselves with just four biscuits to feed on.
153
420266
3758
所以現在我們只剩下四片餅乾能拿來吃
07:19
That is not a superlatively efficient use of global resources,
154
424024
3799
這真的不是利用全球資源最有效的方法
07:23
especially when you think of the billion hungry people
155
427823
2460
尤其是當你想到全球已經有上億的人口
07:26
that exist already in the world.
156
430283
2140
處在飢餓下
07:28
Having gone through the data, I then needed
157
432423
1983
我已經解釋過了我的數據，現在我要
07:30
to demonstrate where that food ends up.
158
434406
3678
告訴你們那些被浪費的食物去了哪裡
07:33
Where does it end up? We're used to seeing the stuff
159
438084
1619
你知道那些食物去了哪裡？我們看慣了
07:35
on our plates, but what about all the stuff
160
439703
1903
食物裝在盤子裡，但是那些
07:37
that goes missing in between?
161
441606
1940
沒有出現在盤子裡的食物呢？
07:39
Supermarkets are an easy place to start.
162
443546
2412
超市是個很容易舉的例子
07:41
This is the result of my hobby,
163
445958
2591
這是我的好習慣的結果
07:44
which is unofficial bin inspections. (Laughter)
164
448549
4476
就是非正式的垃圾桶檢查（笑聲）
07:48
Strange you might think, but if we could rely on corporations
165
453025
2597
你可能覺得奇怪，但是如果你真能相信企業
07:51
to tell us what they were doing in the back of their stores,
166
455622
3108
所宣稱他們在店後面所做的事
07:54
we wouldn't need to go sneaking around the back,
167
458730
2484
我們就不需要偷偷摸摸地繞到後面去
07:57
opening up bins and having a look at what's inside.
168
461214
2556
打開垃圾桶，然後看看裡面到底有什麼
07:59
But this is what you can see more or less on
169
463770
1960
但這就是你在英國、歐洲、北美洲的
08:01
every street corner in Britain, in Europe, in North America.
170
465730
3512
街角或多或少會看見的景象
08:05
It represents a colossal waste of food,
171
469242
3066
這代表著龐大的糧食浪費
08:08
but what I discovered whilst I was writing my book
172
472308
2502
但在我寫書時我發現到
08:10
was that this very evident abundance of waste
173
474810
3344
這罪證確鑿的浪費景象
08:14
was actually the tip of the iceberg.
174
478154
2944
其實只是冰山的一角
08:16
When you start going up the supply chain,
175
481098
2056
當你循著供應鏈向源頭走
08:19
you find where the real food waste is happening
176
483154
2986
你就會發現我們正以
08:22
on a gargantuan scale.
177
486140
1987
龐大的規模浪費食物
08:24
Can I have a show of hands
178
488127
1473
請舉一下手
08:25
if you have a loaf of sliced bread in your house?
179
489600
4458
如果你家裡有一條切好的土司麵包
08:29
Who lives in a household where that crust --
180
494058
1919
誰會把土司麵包皮 --
08:31
that slice at the first and last end of each loaf --
181
495977
3193
就是土司的第一片及最後那一片硬皮 --
08:35
who lives in a household where it does get eaten?
182
499170
2444
誰會把土司麵包皮吃掉？
08:37
Okay, most people, not everyone, but most people,
183
501614
2367
很好，大多數都會，雖然不是每一個人，但大多數都會
08:39
and this is, I'm glad to say, what I see across the world,
184
503981
2456
我很高興地說這也是我在全球看到的現象
08:42
and yet has anyone seen a supermarket or sandwich shop
185
506437
2789
但是在這世界上，誰在超市或三明治店裡
08:45
anywhere in the world that serves sandwiches
186
509226
2236
看過他們拿麵包皮來做三明治？
08:47
with crusts on it? (Laughter)
187
511462
1774
（笑聲）
08:49
I certainly haven't.
188
513236
1583
我可從來沒看過
08:50
So I kept on thinking, where do those crusts go? (Laughter)
189
514819
5168
所以我老在想，到底那些皮去了哪裡？（笑聲）
08:55
This is the answer, unfortunately:
190
519987
2215
很不幸的，這就是答案
08:58
13,000 slices of fresh bread coming out of
191
522202
1912
光是這家工廠每一天就要丟掉一萬三千片
09:00
this one single factory every single day, day-fresh bread.
192
524114
5601
新鮮的麵包皮。剛做好的麵包
09:05
In the same year that I visited this factory,
193
529715
1509
我去參觀這家工廠的同一年
09:07
I went to Pakistan, where people in 2008 were going hungry
194
531224
4450
我也去了巴基斯坦。2008年時那裡的人正餓著肚子
09:11
as a result of a squeeze on global food supplies.
195
535674
3777
說是因為全球糧食供給短缺
09:15
We contribute to that squeeze
196
539451
2184
我們也在這短缺上有份
09:17
by depositing food in bins here in Britain
197
541635
2992
因為無論是在英國這裡或在世界其他地方
09:20
and elsewhere in the world. We take food
198
544627
2207
我們都把食物丟到垃圾桶裡，我們把
09:22
off the market shelves that hungry people depend on.
199
546834
3106
那些飢餓的人所仰賴的食物從貨架上取走！
09:25
Go one step up, and you get to farmers,
200
549940
2550
再沿供給鏈向上走一步，去看看那些農夫
09:28
who throw away sometimes a third or even more
201
552490
2160
有時候他們丟掉三分之一或更多的
09:30
of their harvest because of cosmetic standards.
202
554650
2045
收成，只因為外表不符收購標準
09:32
This farmer, for example, has invested 16,000 pounds
203
556695
2923
舉個例子，這位農夫投資了一萬六千英磅
09:35
in growing spinach, not one leaf of which he harvested,
204
559618
3424
來種植波菜，但是他一片也沒收成
09:38
because there was a little bit of grass growing in amongst it.
205
563042
2454
因為有一些野草長在其中
09:41
Potatoes that are cosmetically imperfect,
206
565496
2480
這些長相不完美的馬鈴薯
09:43
all going for pigs.
207
567976
1533
通通拿來餵豬
09:45
Parsnips that are too small for supermarket specifications,
208
569509
4038
而這些長的太小，不合超市規格的歐洲防風草根（類似蘿蔔）
09:49
tomatoes in Tenerife,
209
573547
2016
西班牙特內里夫的番茄
09:51
oranges in Florida,
210
575563
1805
佛羅里達州的柳橙
09:53
bananas in Ecuador, where I visited last year,
211
577368
3004
還有厄瓜多爾產的香蕉，都是如此。去年我還去過那裡
09:56
all being discarded. This is one day's waste
212
580372
2415
這是厄瓜多爾一處香蕉農園
09:58
from one banana plantation in Ecuador.
213
582787
2537
一天所丟掉的香蕉量
10:01
All being discarded, perfectly edible,
214
585324
2208
這些通通被丟掉，完全可食用
10:03
because they're the wrong shape or size.
215
587532
2488
只因為它們的形狀或尺寸不對
10:05
If we do that to fruit and vegetables,
216
590020
1580
如果我們可以這樣處理水果蔬菜
10:07
you bet we can do it to animals too.
217
591600
2815
沒錯我們也可以這樣處理動物
10:10
Liver, lungs, heads, tails,
218
594415
2739
肝臟、肺部、頭、尾巴
10:13
kidneys, testicles,
219
597154
1978
腎臟、睪丸
10:15
all of these things which are traditional,
220
599132
1713
這些東西在烹飪學裡
10:16
delicious and nutritious parts of our gastronomy
221
600845
2815
都是既傳統又美味營養的東西
10:19
go to waste. Offal consumption has halved
222
603660
3496
我們卻把它丟掉。過去30年英國及美國
10:23
in Britain and America in the last 30 years.
223
607156
2535
內臟食用量少了一半
10:25
As a result, this stuff gets fed to dogs at best,
224
609691
2640
結果就是，最好的情況是拿去餵狗
10:28
or is incinerated.
225
612331
1769
要不然就只好燒掉了
10:30
This man, in Kashgar, Xinjiang province, in Western China,
226
614100
3847
這位仁兄在中國西部新疆省的喀什噶爾
10:33
is serving up his national dish.
227
617947
1915
賣一種國民飲食
10:35
It's called sheep's organs.
228
619862
1715
叫做「麵肺子和米腸子」的羊內臟食品
10:37
It's delicious, it's nutritious,
229
621577
1667
這很美味很營養
10:39
and as I learned when I went to Kashgar,
230
623244
2408
而且我去喀什噶爾時學到
10:41
it symbolizes their taboo against food waste.
231
625652
3069
這象徵著他們對浪費食物的禁忌
10:44
I was sitting in a roadside cafe.
232
628721
2196
有一天我坐在路邊攤
10:46
A chef came to talk to me, I finished my bowl,
233
630917
2604
廚師走過來跟我聊天，我已經吃完了
10:49
and halfway through the conversation, he stopped talking
234
633521
1765
聊到一半的時候他突然停止說話
10:51
and he started frowning into my bowl.
235
635286
2566
然後對著我的碗皺皺眉
10:53
I thought, "My goodness, what taboo have I broken?
236
637852
1879
我心想，我的天我犯了什麼禁忌？
10:55
How have I insulted my host?"
237
639731
1594
我做了什麼得罪了我的店東？
10:57
He pointed at three grains of rice
238
641325
1738
他指著碗底的三粒飯
10:58
at the bottom of my bowl, and he said, "Clean." (Laughter)
239
643063
4284
說：「吃完！」（笑聲）
11:03
I thought, "My God, you know, I go around the world
240
647347
1912
我心想，天啊，你知道嗎，我走遍全世界
11:05
telling people to stop wasting food.
241
649259
1416
告訴大家不要再浪費食物
11:06
This guy has thrashed me at my own game." (Laughter)
242
650675
5049
這傢伙簡直是狠狠地甩了我一巴掌（笑聲）
11:11
But it gave me faith. It gave me faith that we, the people,
243
655724
3223
但這也給了我信心，我相信我們大家
11:14
do have the power to stop this tragic waste of resources
244
658947
5036
的確有能力來停止這樣的浪費資源悲劇
11:19
if we regard it as socially unacceptable
245
663983
2200
如果我們都認為這樣大規模的浪費食物
11:22
to waste food on a colossal scale,
246
666183
1504
是社會不能接受的事
11:23
if we make noise about it, tell corporations about it,
247
667687
2553
如果我們大聲疾呼告訴企業不能再這樣做
11:26
tell governments we want to see an end to food waste,
248
670255
2620
告訴政府我們要看到糧食浪費停止
11:28
we do have the power to bring about that change.
249
672875
2496
我們的確有能力帶來那樣的改變
11:31
Fish, 40 to 60 percent of European fish
250
675371
2712
譬如魚類，百分之40到60的歐洲魚類
11:33
are discarded at sea, they don't even get landed.
251
678083
3081
在海裡捕到就丟了，甚至根本上不了岸
11:37
In our homes, we've lost touch with food.
252
681164
2692
在家裡我們已經跟食物完全脫了節
11:39
This is an experiment I did on three lettuces.
253
683856
2917
我拿了三棵萵苣來做這個實驗
11:42
Who keeps lettuces in their fridge?
254
686773
2638
這裡有誰把萵苣冰在冰箱理？
11:45
Most people. The one on the left
255
689411
3576
大部分人都這麼做。左邊這棵
11:48
was kept in a fridge for 10 days.
256
692987
1453
在冰箱裡冰了10天
11:50
The one in the middle, on my kitchen table. Not much difference.
257
694440
2219
中間這棵放在我的廚房桌子上，兩者沒有什麼不同
11:52
The one on the right I treated like cut flowers.
258
696659
2575
右邊這棵我把它當切花對待
11:55
It's a living organism, cut the slice off,
259
699234
2182
這是棵活的生物，我把它橫切
11:57
stuck it in a vase of water,
260
701416
1443
插在水瓶裡
11:58
it was all right for another two weeks after this.
261
702859
3548
兩個星期後看起來還是很好
12:02
Some food waste, as I said at the beginning,
262
706407
1959
就像我一開場就提到的，浪費糧食的現象
12:04
will inevitably arise, so the question is,
263
708366
1832
必然會增加。所以問題是
12:06
what is the best thing to do with it?
264
710198
2198
要怎麼做才是最好的因應方法？
12:08
I answered that question when I was 15.
265
712396
1506
我在15歲時就回答了這個問題
12:09
In fact, humans answered that question 6,000 years ago:
266
713902
5410
事實上人類早在六千年前就回答了這個問題
12:15
We domesticated pigs
267
719312
2212
我們馴養豬
12:17
to turn food waste back into food.
268
721524
2772
把廚餘再轉變成食物
12:20
And yet, in Europe, that practice has become illegal
269
724296
3731
但是在歐洲自2001年起，因為口蹄疫爆發的關係
12:23
since 2001 as a result of the foot-and-mouth outbreak.
270
728027
3287
餵豬廚餘已經變成不合法
12:27
It's unscientific. It's unnecessary.
271
731314
1901
這個決定既沒有科學根據，也沒有必要
12:29
If you cook food for pigs, just as if
272
733215
2683
如果你把食物煮過再給豬吃，就像
12:31
you cook food for humans, it is rendered safe.
273
735898
2969
你把食物煮過才給人吃，它可證明是安全的
12:34
It's also a massive saving of resources.
274
738867
2560
同時這也大量節省了資源
12:37
At the moment, Europe depends on importing
275
741427
2895
目前歐洲仰賴上百萬噸的
12:40
millions of tons of soy from South America,
276
744322
1666
進口南非黃豆來餵豬
12:41
where its production contributes to global warming,
277
745988
2886
但在南非這項生產
12:44
to deforestation, to biodiversity loss,
278
748874
2600
已造成全球暖化、森林砍伐
12:47
to feed livestock here in Europe.
279
751474
2447
及生物多樣化消失
12:49
At the same time we throw away millions of tons
280
753921
2302
與此同時我們也丟棄了上百萬噸
12:52
of food waste which we could and should be feeding them.
281
756223
3219
可以也應該拿來餵豬的廚餘
12:55
If we did that, and fed it to pigs, we would save
282
759442
2862
如果我們拿廚餘餵豬，我們可以減少
12:58
that amount of carbon.
283
762304
2351
圖上顯示的碳排放量
13:00
If we feed our food waste which is the current
284
764655
3092
如果我們把食品廢棄物
13:03
government favorite way of getting rid of food waste,
285
767747
2295
拿去無氧發酵，這樣會把食品廢棄物
13:05
to anaerobic digestion, which turns food waste
286
770042
2801
轉變成氣體來發電
13:08
into gas to produce electricity,
287
772843
2304
這是目前政府最愛的方法
13:11
you save a paltry 448 kilograms of carbon dioxide
288
775147
3733
但每噸廚餘你只能減少448公斤二氧化碳排放
13:14
per ton of food waste. It's much better to feed it to pigs.
289
778880
2482
多麼微不足道。拿去餵豬比較好
13:17
We knew that during the war. (Laughter)
290
781362
3260
我們在二次大戰時就知道了。（笑聲）
13:20
A silver lining: It has kicked off globally,
291
784622
4274
不過我已看到一線曙光。全球已開始
13:24
the quest to tackle food waste.
292
788896
1770
尋求打擊糧食浪費的方法
13:26
Feeding the 5,000 is an event I first organized in 2009.
293
790666
3854
「餵飽五千人」是我在2009年首次舉辦的活動
13:30
We fed 5,000 people all on food that otherwise
294
794520
2256
我們用原本要被丟棄的食物
13:32
would have been wasted.
295
796776
1398
餵飽了五千人
13:34
Since then, it's happened again in London,
296
798174
2300
之後倫敦也舉辦了一次
13:36
it's happening internationally, and across the country.
297
800474
2133
現在這項活動在國際間舉行，也在全國各地舉行
13:38
It's a way of organizations coming together
298
802607
2343
這是各組織聯合起來
13:40
to celebrate food, to say the best thing to do with food
299
804950
3742
頌讚食物，同時宣告對待食物最好的方法就是
13:44
is to eat and enjoy it, and to stop wasting it.

ABOUT THE SPEAKER
Tristram Stuart - Author and ActivistTristram Stuart sounds the warning bell on global food waste, calling for us to change the systems whereby large quantities of produce and other foods end up in trash heaps.
Why you should listen
Western countries waste up to half of their food. This is an injustice Tristram Stuart has dedicated his career to fixing. In his newest book, Waste: Uncovering the Global Food Scandal, Tristram shows how changing the systems that result in food waste could be one of the simplest ways to reduce pressure on the environment.
The winner of the international environmental award The Sophie Prize in 2011, Tristram is the founder of Feeding the 5000, a consciousness raising campaign where 5000 members of the public are given a free lunch using only ingredients that otherwise would have been wasted. Held in Trafalgar Square in 2009 and 2011, the event has also been held internationally.
In addition, Tristram works with a range of NGOs, governments, and private enterprises to tackle the global food waste scandal.
