The job of uncovering the global food waste scandal

这项揭露全球粮食浪费丑闻的任务
00:19
started for me when I was 15 years old.
1
3717
3018
从我15岁起便开始了。
00:22
I bought some pigs. I was living in Sussex.
2
6735
2521
我买了一些猪。当时我住在萨塞克斯郡。
00:25
And I started to feed them in the most traditional
3
9256
2383
我开始用最传统
00:27
and environmentally friendly way.
4
11639
1971
和环保的方式饲养它们。
00:29
I went to my school kitchen, and I said,
5
13610
2325
我去了学校的厨房，我说，
00:31
"Give me the scraps that my school friends have turned
6
15935
1546
“把那些我朋友们所看不上的
00:33
their noses up at."
7
17481
866
残羹剩饭都给我。”
00:34
I went to the local baker and took their stale bread.
8
18347
2664
我去了当地的面包店，向他们要了那些不新鲜的面包。
00:36
I went to the local greengrocer, and I went to a farmer
9
21011
2732
我去了当地的蔬菜水果店，还去找了一个
00:39
who was throwing away potatoes because they were
10
23743
1838
正在丢弃土豆的农民，
00:41
the wrong shape or size for supermarkets.
11
25581
3186
仅仅是因为它们形状和尺寸不符合超市的需求。
00:44
This was great. My pigs turned that food waste
12
28767
3089
一切都很顺利。我养的那些猪把食物残渣
00:47
into delicious pork. I sold that pork
13
31856
2657
都转变成了美味的猪肉。我把猪肉
00:50
to my school friends' parents, and I made
14
34513
1987
卖给学校里朋友们的家长，并且我也从中赚到
00:52
a good pocket money addition to my teenage allowance.
15
36500
4637
额外的零花钱。
00:57
But I noticed that most of the food that I was giving my pigs
16
41137
2882
但是后来我意识到，我喂猪所用的大部分食物
00:59
was in fact fit for human consumption,
17
44019
2383
都是人类可食用的，
01:02
and that I was only scratching the surface,
18
46402
2269
而我也只触到了问题表面，
01:04
and that right the way up the food supply chain,
19
48671
2862
在整条食物链的最上面，
01:07
in supermarkets, greengrocers, bakers, in our homes,
20
51533
3218
在超市里，在蔬菜水果店里，在面包店里，在我们的家里，
01:10
in factories and farms, we were hemorrhaging out food.
21
54751
3260
在工厂和农场里，我们都在大量地、疯狂地浪费着食物。
01:13
Supermarkets didn't even want to talk to me
22
58011
2597
那些超市的负责人甚至都不愿意跟我讨论
01:16
about how much food they were wasting.
23
60608
1374
那些他们到底浪费了多少粮食的话题。
01:17
I'd been round the back. I'd seen bins full of food
24
61982
2484
我曾经绕到超市的后面。我亲眼目睹了那些装满食物的垃圾桶
01:20
being locked and then trucked off to landfill sites,
25
64466
2751
被锁在卡车里，然后被送往垃圾场填埋，
01:23
and I thought, surely there is something more sensible
26
67217
3021
然后我就在想，肯定有更合理的处理食物的方法，
01:26
to do with food than waste it.
27
70238
3167
而不是浪费它们。
01:29
One morning, when I was feeding my pigs,
28
73405
2305
一天早上，当我正在喂我的猪时，
01:31
I noticed a particularly tasty-looking sun-dried tomato loaf
29
75710
3687
我看到一块看起来很美味的晒干的西红柿面包，
01:35
that used to crop up from time to time.
30
79397
2075
它们常常会出现。
01:37
I grabbed hold of it,
31
81472
1402
我抓起了它，
01:38
sat down, and ate my breakfast with my pigs. (Laughter)
32
82874
3546
坐了下来，跟我的那些猪共进早餐。（笑声）
01:42
That was the first act of what I later learned to call freeganism,
33
86420
3120
这就是我第一次做出这种后来被我称呼为“免费素食主义"的举动，
01:45
really an exhibition of the injustice of food waste,
34
89540
4255
实际上体现出的是对浪费食物的不满，
01:49
and the provision of the solution to food waste,
35
93795
2350
并且提供了浪费食物的解决方案，
01:52
which is simply to sit down and eat food,
36
96145
2654
那就是，坐下来，吃完它，
01:54
rather than throwing it away.
37
98799
1488
而不是把它丢掉。
01:56
That became, as it were, a way of confronting
38
100287
3279
这种行为变成一种对大型产业
01:59
large businesses in the business of wasting food,
39
103566
2987
浪费食物行为的抵抗，
02:02
and exposing, most importantly, to the public,
40
106553
2521
更重要的是，去向大众揭露，
02:04
that when we're talking about food being thrown away,
41
109074
2170
当我们在说被丢弃的食品时，
02:07
we're not talking about rotten stuff, we're not talking about
42
111244
2139
我们说的不是腐烂的食品，我们说的不是
02:09
stuff that's beyond the pale.
43
113383
2712
那些难以下咽的食物。
02:11
We're talking about good, fresh food that is being wasted
44
116095
2116
我们说的是那些完好的，新鲜的食物
02:14
on a colossal scale.
45
118211
2538
在被大规模地浪费掉。
02:16
Eventually, I set about writing my book,
46
120749
1857
终于，我决定写一本书，
02:18
really to demonstrate the extent of this problem
47
122606
2054
来说明这个问题在国际上的广度。
02:20
on a global scale. What this shows is
48
124660
3396
这个显示出的是
02:23
a nation-by-nation breakdown of the likely level
49
128056
3479
世界上每个国家对食物可能的
02:27
of food waste in each country in the world.
50
131535
3102
浪费程度。
02:30
Unfortunately, empirical data, good, hard stats, don't exist,
51
134637
3888
但是很可惜，实际、确凿的数据很难统计，
02:34
and therefore to prove my point, I first of all had to find
52
138525
2482
因此，为了证明我的观点，我首先得通过
02:36
some proxy way of uncovering
53
141007
2153
一些替代的方式来揭露
02:39
how much food was being wasted.
54
143160
2245
有多少食物被浪费了。
02:41
So I took the food supply of every single country
55
145405
2556
于是，我把各国的食物供应量
02:43
and I compared it to what was actually likely
56
147961
3042
跟其自身的实际消耗量
02:46
to be being consumed in each country.
57
151003
2032
拿来做比较。
02:48
That's based on diet intake surveys, it's based on
58
153035
3887
这些数据是基于食物摄入量的调查问卷基础上，
02:52
levels of obesity, it's based on a range of factors
59
156922
2666
再加上肥胖程度和很多其他不同的因素，
02:55
that gives you an approximate guess
60
159588
1342
来得出一个大概的
02:56
as to how much food is actually going into people's mouths.
61
160930
3227
关于究竟有多少食物真正进入了人们的口中的推测。
03:00
That black line in the middle of that table
62
164157
2729
表格中间的黑线
03:02
is the likely level of consumption
63
166886
2996
是食物消耗量的大概数值
03:05
with an allowance for certain levels of inevitable waste.
64
169882
4362
当中包括了一定量的无法避免的浪费。
03:10
There will always be waste. I'm not that unrealistic
65
174244
1919
浪费永远都会存在。 我还不至于不切实际到去
03:12
that I think we can live in a waste-free world.
66
176163
1980
以为我们可以生活在一个毫无浪费的世界里。
03:14
But that black line shows what a food supply should be
67
178143
3873
但是那条黑线显示出
03:17
in a country if they allow for a good, stable, secure,
68
182016
4454
一个具备良好的，稳定的，安全的
03:22
nutritional diet for every person in that country.
69
186470
3749
有营养的食品的国家应该供应给每个人的食物量。
03:26
Any dot above that line, and you'll quickly notice that
70
190219
2407
你会发现，世界上绝大多数的国家
03:28
that includes most countries in the world,
71
192626
2701
都处于这条线的上方，
03:31
represents unnecessary surplus, and is likely to reflect
72
195327
4289
代表着不必要的盈余，也反映出
03:35
levels of waste in each country.
73
199616
2622
每个国家的食物浪费量。
03:38
As a country gets richer, it invests more and more
74
202238
3269
当一个国家变富裕时，它会投入越来越多的资产
03:41
in getting more and more surplus
75
205507
1291
来购买大量的、额外的存货
03:42
into its shops and restaurants,
76
206798
2810
导致商店和餐馆里产生更多的浪费，
03:45
and as you can see, most European
77
209608
2056
同时你可以看到，大多数欧洲
03:47
and North American countries
78
211664
1412
和北美的国家
03:48
fall between 150 and 200 percent
79
213076
3140
消耗着150％到200％的
03:52
of the nutritional requirements of their populations.
80
216216
3380
国家总人口营养需求量。
03:55
So a country like America has twice as much food
81
219596
2408
所以一个像美国这样的国家
03:57
on its shop shelves and in its restaurants
82
222004
2604
在它商店货架上和餐馆里所拥有的食物
04:00
than is actually required to feed the American people.
83
224608
3568
比实际需要喂饱所有美国人的量还多出一倍。
04:04
But the thing that really struck me,
84
228176
1560
但是当我处理这些大量的数据时，
04:05
when I plotted all this data, and it was a lot of numbers,
85
229736
4215
一件深深震撼我的事就是，
04:09
was that you can see how it levels off.
86
233951
3666
如你所见，数据点逐渐趋于平缓。
04:13
Countries rapidly shoot towards that 150 mark,
87
237617
3068
各个国家的点很快升至150的标记，而在到达这个界限后
04:16
and then they level off, and they don't really go on rising
88
240685
3288
便趋于平稳，而非像你所预期的那样
04:19
as you might expect.
89
243973
1546
继续上升。
04:21
So I decided to unpack that data a little bit further
90
245519
2545
所以我决定更近一步的解读这些数据
04:23
to see if that was true or false.
91
248064
2285
来看这到底是准确的还是错误的。
04:26
And that's what I came up with.
92
250349
1494
这就是我所发现的。
04:27
If you include not just the food that ends up
93
251843
1927
如果不仅仅包括是那些最终
04:29
in shops and restaurants, but also the food
94
253770
2124
流向在商店和餐馆的食物，而且还包括
04:31
that people feed to livestock,
95
255894
2156
人们用来饲养牲畜的食物：
04:33
the maize, the soy, the wheat, that humans could eat
96
258050
3503
那些玉米、大豆、小麦，等等人类本可以食用
04:37
but choose to fatten livestock instead to produce
97
261553
2481
但是却选择给牲畜用来增肥
04:39
increasing amounts of meat and dairy products,
98
264034
1931
以便制造更多肉类和奶制品，
04:41
what you find is that most rich countries
99
265965
1667
你会发现，大多数富裕的国家
04:43
have between three and four times the amount of food
100
267632
4323
消耗着它人口所需要的
04:47
that their population needs to feed itself.
101
271955
3084
三到四倍多的食物。
04:50
A country like America has four times the amount of food
102
275039
3283
一个像美国这样的国家有着它人口所需要的
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
当人们在讨论着需要扩大全球
05:00
food production to feed those nine billion people
105
284246
2660
粮食产量来喂饱2050年之际
05:02
that are expected on the planet by 2050,
106
286906
2512
预计的全球90亿人口，
05:05
I always think of these graphs.
107
289418
1721
我总是会想起这些图表。
05:07
The fact is, we have an enormous buffer
108
291139
2951
实际上，富裕的国家为我们和饥饿之间
05:09
in rich countries between ourselves and hunger.
109
294090
3881
提供庞大的缓冲。
05:13
We've never had such gargantuan surpluses before.
110
297971
4676
我们之前从未有过如此庞大的盈余。
05:18
In many ways, this is a great success story
111
302647
2666
在很多方面，这是一个人类文明的成功的故事：
05:21
of human civilization, of the agricultural surpluses
112
305313
4139
在农业富余方面
05:25
that we set out to achieve 12,000 years ago.
113
309452
3353
我们达到了12,000年前所定的目标。
05:28
It is a success story. It has been a success story.
114
312805
3557
这是一个成功的故事。这一直都是一个成功的故事。
05:32
But what we have to recognize now is that we are
115
316362
2537
但是我们现在要认识到的是我们已经
05:34
reaching the ecological limits that our planet can bear,
116
318899
3632
要达到地球所能承受的生态极限，
05:38
and when we chop down forests, as we are every day,
117
322531
2637
每天，当我们砍下一片片树林，
05:41
to grow more and more food,
118
325168
1348
来增加越来越多的食物，
05:42
when we extract water from depleting water reserves,
119
326516
3748
当我们从渐渐耗尽的水资源中提取水，
05:46
when we emit fossil fuel emissions in the quest
120
330264
3388
当我们排放着化石燃料的废气
05:49
to grow more and more food,
121
333652
1292
来增加越来越多的食物，
05:50
and then we throw away so much of it,
122
334944
2851
然后再把这么多的食物都丢弃，
05:53
we have to think about what we can start saving.
123
337795
2936
我们必须想一想我们能开始保存下些什么。
05:56
And yesterday, I went to one of the local supermarkets
124
340731
3725
昨天，我去了一家我常去的
06:00
that I often visit to
125
344456
2216
本地的超市
06:02
inspect, if you like, what they're throwing away.
126
346672
4181
去察看他们丢弃了些什么。
06:06
I found quite a few packets of biscuits amongst
127
350853
2403
我找到了很多包饼干
06:09
all the fruit and vegetables and everything else
128
353256
1627
还有很多水果蔬菜和其他的一些东西
06:10
that was in there.
129
354883
947
都在废弃物之列。
06:11
And I thought, well this could serve as a symbol for today.
130
355830
2440
然后我想到，这个可以作为今天的一个象征。
06:14
So I want you to imagine that these nine biscuits
131
358270
2435
所以我想让你们把这9块我在垃圾桶里找到的饼干
06:16
that I found in the bin represent the global food supply,
132
360705
3528
想象成全球粮食供应，
06:20
okay? We start out with nine.
133
364233
1601
好吗？我们最初有9块。
06:21
That's what's in fields around the world every single year.
134
365834
3483
这是全球每年的食物产量。
06:25
The first biscuit we're going to lose
135
369317
1761
第一块饼干在我们离开农场之前
06:26
before we even leave the farm.
136
371078
1759
就会失去。
06:28
That's a problem primarily associated with
137
372837
3265
这个问题主要与
06:32
developing work agriculture, whether it's
138
376102
1664
农业工作发展有关，不管它是
06:33
a lack of infrastructure, refrigeration, pasteurization,
139
377766
2505
缺乏基础设施，制冷设备，杀菌技术，
06:36
grain stores, even basic fruit crates, which means
140
380271
2913
以及粮油店，甚至基本的水果箱，这意味着
06:39
that food goes to waste before it even leaves the fields.
141
383184
3749
食物在离开产地之前就会被浪费掉。
06:42
The next three biscuits are the foods that we decide
142
386933
3496
下面三块饼干是在我们决定用来
06:46
to feed to livestock, the maize, the wheat and the soya.
143
390429
3740
饲养牲畜用的食物：玉米，小麦和大豆。
06:50
Unfortunately, our beasts are inefficient animals,
144
394169
4844
不幸的是，我们的野兽们是低效的动物们，
06:54
and they turn two-thirds of that into feces and heat,
145
399013
4175
它们把2/3都转换成粪便和热量，
06:59
so we've lost those two, and we've only kept this one
146
403188
2618
因此我们丢失了两块饼干，我们只保留下这一块
07:01
in meat and dairy products.
147
405806
2234
代表肉类和奶制品。
07:03
Two more we're going to throw away directly into bins.
148
408040
3584
还有两块我们会直接丢进垃圾桶里。
07:07
This is what most of us think of when we think
149
411624
1553
这就是我们大多数人所认为的
07:09
of food waste, what ends up in the garbage,
150
413177
2511
食物浪费，那些最终到了垃圾桶里的，
07:11
what ends up in supermarket bins,
151
415688
1848
最终到了超市的垃圾桶里的，
07:13
what ends up in restaurant bins. We've lost another two,
152
417536
2730
最终到了餐馆的垃圾桶里的。于是我们又失去了两块，
07:16
and we've left ourselves with just four biscuits to feed on.
153
420266
3758
而我们只为自己留下四块能食用的饼干。
07:19
That is not a superlatively efficient use of global resources,
154
424024
3799
这种利用全球资源的方式并不高效，
07:23
especially when you think of the billion hungry people
155
427823
2460
特别是当你想起这个世界上有多少亿的人们
07:26
that exist already in the world.
156
430283
2140
正在挨饿着。
07:28
Having gone through the data, I then needed
157
432423
1983
研究过这些数据，我还需要
07:30
to demonstrate where that food ends up.
158
434406
3678
演示这些食物最终去了那里。
07:33
Where does it end up? We're used to seeing the stuff
159
438084
1619
它去了哪里呢？我们习惯于看到那些在我们盘子上的
07:35
on our plates, but what about all the stuff
160
439703
1903
食物，但是那些在这之前不见的
07:37
that goes missing in between?
161
441606
1940
食物去了哪里呢？
07:39
Supermarkets are an easy place to start.
162
443546
2412
超市是个容易开始着手的地方。
07:41
This is the result of my hobby,
163
445958
2591
而这是我爱好的结果，
07:44
which is unofficial bin inspections. (Laughter)
164
448549
4476
就是非官方的垃圾桶检查。（笑声）
07:48
Strange you might think, but if we could rely on corporations
165
453025
2597
你会想这很奇怪，但是如果我们能靠企业
07:51
to tell us what they were doing in the back of their stores,
166
455622
3108
来告诉我们他们在店里都在做些什么，
07:54
we wouldn't need to go sneaking around the back,
167
458730
2484
我们就不必要偷偷摸摸的跑到店后面，
07:57
opening up bins and having a look at what's inside.
168
461214
2556
打开垃圾桶去看里面有什么。
07:59
But this is what you can see more or less on
169
463770
1960
但是这就是你或多或少
08:01
every street corner in Britain, in Europe, in North America.
170
465730
3512
能在英国，欧洲和北美的大街小巷里看到的。
08:05
It represents a colossal waste of food,
171
469242
3066
这表明了庞大的食物浪费，
08:08
but what I discovered whilst I was writing my book
172
472308
2502
但是在写书期间我发现
08:10
was that this very evident abundance of waste
173
474810
3344
这些显而易见的大量浪费
08:14
was actually the tip of the iceberg.
174
478154
2944
其实只是冰山一角。
08:16
When you start going up the supply chain,
175
481098
2056
当你开始从食物供应链往上，
08:19
you find where the real food waste is happening
176
483154
2986
你就会发现庞大规模的食物浪费
08:22
on a gargantuan scale.
177
486140
1987
正在发生
08:24
Can I have a show of hands
178
488127
1473
我想让在座的各位来次举手投票：
08:25
if you have a loaf of sliced bread in your house?
179
489600
4458
如果你的家里有一条切片面包，
08:29
Who lives in a household where that crust --
180
494058
1919
谁会把那些面包皮——
08:31
that slice at the first and last end of each loaf --
181
495977
3193
就是那第一片和最后一片面包片——
08:35
who lives in a household where it does get eaten?
182
499170
2444
哪些家庭会把这些吃掉？
08:37
Okay, most people, not everyone, but most people,
183
501614
2367
好的，大部分人，不是所有人，但是绝大多数人，
08:39
and this is, I'm glad to say, what I see across the world,
184
503981
2456
而这也是，我很高兴地说，全球都是这样，
08:42
and yet has anyone seen a supermarket or sandwich shop
185
506437
2789
但是有没有人看到超市或者三明治店里
08:45
anywhere in the world that serves sandwiches
186
509226
2236
世上任何地方卖的三明治
08:47
with crusts on it? (Laughter)
187
511462
1774
上面有面包皮？（笑声）
08:49
I certainly haven't.
188
513236
1583
至少我没见过。
08:50
So I kept on thinking, where do those crusts go? (Laughter)
189
514819
5168
所以我继续想，这些面包皮都去了哪里？（笑声）
08:55
This is the answer, unfortunately:
190
519987
2215
这就是答案，很不幸：
08:58
13,000 slices of fresh bread coming out of
191
522202
1912
每天都有13,000块新鲜面包
09:00
this one single factory every single day, day-fresh bread.
192
524114
5601
从这一个工厂里产出，这是非常新鲜的、刚出炉的面包。
09:05
In the same year that I visited this factory,
193
529715
1509
在我访问这个工厂的同一年，
09:07
I went to Pakistan, where people in 2008 were going hungry
194
531224
4450
我去了巴基斯坦，那儿2008年时还有很多人还在挨饿。
09:11
as a result of a squeeze on global food supplies.
195
535674
3777
这是全球粮食供应紧张造成的。
09:15
We contribute to that squeeze
196
539451
2184
是我们导致了供给紧张，
09:17
by depositing food in bins here in Britain
197
541635
2992
我们把食物丢进英国垃圾桶里
09:20
and elsewhere in the world. We take food
198
544627
2207
还有世界各处。我们把
09:22
off the market shelves that hungry people depend on.
199
546834
3106
那些饥饿的人赖以生存的食物从商店货架上拿了下来。
09:25
Go one step up, and you get to farmers,
200
549940
2550
往上走一步，你就能找到农民，
09:28
who throw away sometimes a third or even more
201
552490
2160
他们把三分之一或者更多的
09:30
of their harvest because of cosmetic standards.
202
554650
2045
收成都丢掉，只因为外形标准。
09:32
This farmer, for example, has invested 16,000 pounds
203
556695
2923
举例说，这个农民投资了16,000英镑
09:35
in growing spinach, not one leaf of which he harvested,
204
559618
3424
来种菠菜，但是没有收割一片叶子，
09:38
because there was a little bit of grass growing in amongst it.
205
563042
2454
因为菠菜之间长了一些草。
09:41
Potatoes that are cosmetically imperfect,
206
565496
2480
那些外形不完美的土豆
09:43
all going for pigs.
207
567976
1533
都归猪所有。
09:45
Parsnips that are too small for supermarket specifications,
208
569509
4038
对超市来说太小的欧洲萝卜，
09:49
tomatoes in Tenerife,
209
573547
2016
特内里费的西红柿，
09:51
oranges in Florida,
210
575563
1805
佛罗里达的橙子，
09:53
bananas in Ecuador, where I visited last year,
211
577368
3004
厄瓜多尔的香蕉，那是我去年去过的地方，
09:56
all being discarded. This is one day's waste
212
580372
2415
都被丢弃了。这是厄瓜多尔的
09:58
from one banana plantation in Ecuador.
213
582787
2537
一个香蕉种植园一天之内的废弃量。
10:01
All being discarded, perfectly edible,
214
585324
2208
全部被丢弃了，明明完全都能食用，
10:03
because they're the wrong shape or size.
215
587532
2488
只因为它们的形状或者大小不对。
10:05
If we do that to fruit and vegetables,
216
590020
1580
如果我们对水果和蔬菜这样做，
10:07
you bet we can do it to animals too.
217
591600
2815
我们肯定也会这样对待动物。
10:10
Liver, lungs, heads, tails,
218
594415
2739
肝脏，肺脏，头部，尾部，
10:13
kidneys, testicles,
219
597154
1978
肾脏，睾丸，
10:15
all of these things which are traditional,
220
599132
1713
所有这些被丢弃的脏器都是传统意义上
10:16
delicious and nutritious parts of our gastronomy
221
600845
2815
可口又营养的美食部分。
10:19
go to waste. Offal consumption has halved
222
603660
3496
最近30年，内脏消费量在
10:23
in Britain and America in the last 30 years.
223
607156
2535
英国和美国减少了一半。
10:25
As a result, this stuff gets fed to dogs at best,
224
609691
2640
结果是，这些东西最好的下场是喂狗吃了，
10:28
or is incinerated.
225
612331
1769
或者被焚烧。
10:30
This man, in Kashgar, Xinjiang province, in Western China,
226
614100
3847
这个男人，在中国西部的新疆省喀什市，
10:33
is serving up his national dish.
227
617947
1915
正在做他的民族佳肴。
10:35
It's called sheep's organs.
228
619862
1715
它叫做羊内脏。
10:37
It's delicious, it's nutritious,
229
621577
1667
既美味又有营养，
10:39
and as I learned when I went to Kashgar,
230
623244
2408
还有我去喀什的时候学到，
10:41
it symbolizes their taboo against food waste.
231
625652
3069
它代表食物浪费的禁忌。
10:44
I was sitting in a roadside cafe.
232
628721
2196
当我坐在路边的咖啡馆里，
10:46
A chef came to talk to me, I finished my bowl,
233
630917
2604
一个厨师来跟我说话，我刚吃完了我碗里的饭，
10:49
and halfway through the conversation, he stopped talking
234
633521
1765
而话谈到一半，他不说话了
10:51
and he started frowning into my bowl.
235
635286
2566
然后开始对着我的碗皱眉头。
10:53
I thought, "My goodness, what taboo have I broken?
236
637852
1879
我想，“天啊，我打破了哪些禁忌？
10:55
How have I insulted my host?"
237
639731
1594
我如何侮辱了这个厨师？“
10:57
He pointed at three grains of rice
238
641325
1738
他指着我碗底的三粒米，
10:58
at the bottom of my bowl, and he said, "Clean." (Laughter)
239
643063
4284
然后说"吃干净。" (笑声）
11:03
I thought, "My God, you know, I go around the world
240
647347
1912
我想，”天啊，你知道，我到世界各地
11:05
telling people to stop wasting food.
241
649259
1416
告诉大家停止浪费食物。
11:06
This guy has thrashed me at my own game." (Laughter)
242
650675
5049
这个人居然在我的游戏里让我输得一败涂地。”(笑声）
11:11
But it gave me faith. It gave me faith that we, the people,
243
655724
3223
但是这给了我信心。它给了我信心，我们人类
11:14
do have the power to stop this tragic waste of resources
244
658947
5036
有力量来停止这种悲剧般的资源浪费
11:19
if we regard it as socially unacceptable
245
663983
2200
如果我们把大规模的食物浪费视作
11:22
to waste food on a colossal scale,
246
666183
1504
不被社会接受的，
11:23
if we make noise about it, tell corporations about it,
247
667687
2553
如果我们发出声音，告诉企业，
11:26
tell governments we want to see an end to food waste,
248
670255
2620
告诉政府我们不想再看到食物被浪费，
11:28
we do have the power to bring about that change.
249
672875
2496
我们有能力来带来变化。
11:31
Fish, 40 to 60 percent of European fish
250
675371
2712
鱼，40%到60%的欧洲的鱼
11:33
are discarded at sea, they don't even get landed.
251
678083
3081
被丢弃在海里，他们甚至都没上过岸。
11:37
In our homes, we've lost touch with food.
252
681164
2692
在我们的家里，我们已经失去了与食品的接触。
11:39
This is an experiment I did on three lettuces.
253
683856
2917
这是一个我在三棵生菜上做的实验。
11:42
Who keeps lettuces in their fridge?
254
686773
2638
谁把生菜放在冰箱里？
11:45
Most people. The one on the left
255
689411
3576
大部分人。左边的
11:48
was kept in a fridge for 10 days.
256
692987
1453
是在冰箱放了10天的。
11:50
The one in the middle, on my kitchen table. Not much difference.
257
694440
2219
中间的那棵，是放在我厨房桌上的。没什么区别。
11:52
The one on the right I treated like cut flowers.
258
696659
2575
右边的这棵我把它视为精心修剪的花。
11:55
It's a living organism, cut the slice off,
259
699234
2182
它是一个有生命的机体，我把它一片一片切下来，
11:57
stuck it in a vase of water,
260
701416
1443
放在一个有水的花瓶里，
11:58
it was all right for another two weeks after this.
261
702859
3548
它在两周后都是好的。
12:02
Some food waste, as I said at the beginning,
262
706407
1959
有些食物浪费，像我在一开始说的那样，
12:04
will inevitably arise, so the question is,
263
708366
1832
是不可避免的，所以问题是，
12:06
what is the best thing to do with it?
264
710198
2198
最好的解决方法是什么？
12:08
I answered that question when I was 15.
265
712396
1506
我15岁就回答了那个问题。
12:09
In fact, humans answered that question 6,000 years ago:
266
713902
5410
实际上，人类在6,000年前就回答了这个问题：
12:15
We domesticated pigs
267
719312
2212
我们驯化了猪，
12:17
to turn food waste back into food.
268
721524
2772
把食物残渣转换成食物。
12:20
And yet, in Europe, that practice has become illegal
269
724296
3731
然而，在欧洲，这种做法已成为非法行为
12:23
since 2001 as a result of the foot-and-mouth outbreak.
270
728027
3287
自从2001年口蹄疫爆发后。
12:27
It's unscientific. It's unnecessary.
271
731314
1901
这不科学，也毫无必要。
12:29
If you cook food for pigs, just as if
272
733215
2683
如果你做饭给猪，就像
12:31
you cook food for humans, it is rendered safe.
273
735898
2969
你做饭给人类一样，就是安全的。
12:34
It's also a massive saving of resources.
274
738867
2560
同时也能减少很多资源利用。
12:37
At the moment, Europe depends on importing
275
741427
2895
现在，欧洲依赖着从南美进口
12:40
millions of tons of soy from South America,
276
744322
1666
几百万吨黄豆，
12:41
where its production contributes to global warming,
277
745988
2886
其生产导致全球气候变暖，
12:44
to deforestation, to biodiversity loss,
278
748874
2600
大片森林遭砍伐以及生物多样性的丧失，
12:47
to feed livestock here in Europe.
279
751474
2447
来饲养在欧洲的牲畜。
12:49
At the same time we throw away millions of tons
280
753921
2302
同时我们扔掉几百万吨
12:52
of food waste which we could and should be feeding them.
281
756223
3219
可以饲养这些牲畜的食物。
12:55
If we did that, and fed it to pigs, we would save
282
759442
2862
如果我们那样做了，把它喂给猪，我们可以减少
12:58
that amount of carbon.
283
762304
2351
那么多的二氧化碳。
13:00
If we feed our food waste which is the current
284
764655
3092
如果我们浪费的食物，
13:03
government favorite way of getting rid of food waste,
285
767747
2295
这是现在政府最喜欢用的处理剩余的食物的方法，
13:05
to anaerobic digestion, which turns food waste
286
770042
2801
进行厌氧消化，将食物渣滓
13:08
into gas to produce electricity,
287
772843
2304
转换成汽油来生产电，
13:11
you save a paltry 448 kilograms of carbon dioxide
288
775147
3733
你能省下微不足道的448公斤的二氧化碳
13:14
per ton of food waste. It's much better to feed it to pigs.
289
778880
2482
在每吨食物残渣里。把这些食物残渣喂给猪更好。
13:17
We knew that during the war. (Laughter)
290
781362
3260
在战争时期我们就懂得。（笑声）
13:20
A silver lining: It has kicked off globally,
291
784622
4274
有一线希望：它在全球已经拉开序幕，
13:24
the quest to tackle food waste.
292
788896
1770
就是寻求解决粮食的浪费的方法。
13:26
Feeding the 5,000 is an event I first organized in 2009.
293
790666
3854
Feeding the 5000是一个我在2009年第一次组织的活动。
13:30
We fed 5,000 people all on food that otherwise
294
794520
2256
我们用本会被丢弃的食物
13:32
would have been wasted.
295
796776
1398
喂饱了5000个人。
13:34
Since then, it's happened again in London,
296
798174
2300
从那以后，在伦敦又进行过一次，
13:36
it's happening internationally, and across the country.
297
800474
2133
全国各地以及国际上也在进行着。
13:38
It's a way of organizations coming together
298
802607
2343
这是所有组织在一起
13:40
to celebrate food, to say the best thing to do with food
299
804950
3742
赞美食物，并同意处理食物的最好方法
13:44
is to eat and enjoy it, and to stop wasting it.
300
808692
2807
就是吃它和享受它，而不要去浪费。
13:47
For the sake of the planet we live on,
301
811499
2593
为了我们所赖以生存在的地球，

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.
