Because of what I'm about to say,
0
16160
2000
因为我等会谈论的议题的缘故
00:18
I really should establish my green credentials.
1
18160
3000
我想我必须首先讲述一下我的绿色情结
00:21
When I was a small boy, I took my pledge
2
21160
2000
当我还是一个小男孩,我承诺
00:23
as an American, to save and faithfully defend from waste
3
23160
3000
作为一名美国人,要保护和忠实地捍卫
00:26
the natural resources of my country,
4
26160
2000
我国的自然资源。
00:28
its air, soil and minerals, its forests, waters and wildlife.
5
28160
3000
这包括空气,土壤,矿物资源,森林,水资源和野生动物。
00:31
And I've stuck to that.
6
31160
2000
我还坚持这一承诺。
00:33
Stanford, I majored in ecology and evolution.
7
33160
4000
在斯坦福大学,我主修生态学和生物进化学。
00:37
1968, I put out the Whole Earth Catalog. Was "mister natural" for a while.
8
37160
4000
1968年我创办了《地球目录》 一段时间我成了 “环保先生”。
00:41
And then worked for the Jerry Brown administration.
9
41160
3000
然后就职于杰里布朗政府。
00:44
The Brown administration, and a bunch of my friends,
10
44160
3000
布朗政府期间,我和一些朋友们
00:47
basically leveled the energy efficiency of California,
11
47160
3000
主要使加州能源效率平衡。
00:50
so it's the same now, 30 years later,
12
50160
3000
因此到现在,30年后,
00:53
even though our economy has gone up 80 percent, per capita.
13
53160
4000
尽管我们的人均经济提高了百分之八十。
00:57
And we are putting out less greenhouse gasses than any other state.
14
57160
3000
但我们加州比任何其他州排放越来越少的温室气体。
01:00
California is basically the equivalent of Europe, in this.
15
60160
3000
在减少温室气体排放这点,加州基本上相当于欧洲。
01:03
This year, Whole Earth Catalog has a supplement that I'll preview today,
16
63160
5000
今年,地球目录有一个补充,今天,我将
01:08
called Whole Earth Discipline.
17
68160
3000
其称为“地球规则”。
01:11
The dominant demographic event of our time
18
71160
2000
现在主要人口事件
01:13
is this screamingly rapid urbanization
19
73160
3000
是我们已经经历过的这种令人讶异的快速城市化
01:16
that we have going on.
20
76160
2000
进程。
01:18
By mid-century we'll be about 80 percent urban,
21
78160
4000
到本世纪中叶将有大约80%要城市化。
01:22
and that's mostly in the developing world,
22
82160
3000
而这主要是在发展中世界
01:25
where that's happening.
23
85160
2000
要发生的事情。
01:27
It's interesting, because history is driven to a large degree
24
87160
3000
有趣的是,在很大程度上
01:30
by the size of cities.
25
90160
2000
城市的大小往往也决定了历史的发展
01:32
The developing world now has all of the biggest cities,
26
92160
3000
现在最大的城市都在发展中国家
01:35
and they are developing three times faster than the developed countries,
27
95160
3000
他们的发展比发达国家的发展快3倍。
01:38
and nine times bigger.
28
98160
2000
规模是我们的9倍
01:40
It's qualitatively different.
29
100160
3000
这是有质的不同。
01:43
They are the drivers of history, as we see by looking at history.
30
103160
2000
当我们回顾历史时,它们是历史转变的驱动力。
01:45
1,000 years ago this is what the world looked like.
31
105160
4000
一千年前的世界是什么样子。
01:49
Well we now have a distribution of urban power
32
109160
3000
那么,我们现在有一个城市发展分布
01:52
similar to what we had 1,000 years ago.
33
112160
3000
类似于我们在1000年前城市分布。
01:55
In other words, the rise of the West,
34
115160
2000
换言之,西方的崛起,
01:57
dramatic as it was, is over.
35
117160
4000
尽管有如一出戏剧,但它已经结束了。
02:01
The aggregate numbers are absolutely overwhelming:
36
121160
3000
总人口数有压倒性的优势。
02:04
1.3 million people a week coming to town,
37
124160
3000
每星期130万人来到城镇,
02:07
decade after decade.
38
127160
2000
年复一年。
02:09
What's really going on?
39
129160
2000
到底是怎么回事?
02:11
Well, what's going on is the villages of the world are emptying out.
40
131160
3000
如今全球各地的村庄正变得荒芜起来
02:14
Subsistence farming is drying up basically.
41
134160
3000
农田没人管,因为人都迁移到了城市
02:17
People are following opportunity into town.
42
137160
2000
城市就是机会
02:19
And this is why.
43
139160
2000
就这么简单
02:21
I used to have a very romantic idea about villages,
44
141160
2000
我曾经有一个关于村庄很浪漫的看法,
02:23
and it's because I never lived in one.
45
143160
3000
这是因为我从来没有在村庄居住过。
02:26
(Laughter)
46
146160
1000
(笑声)
02:27
Because in town --
47
147160
2000
因为在城市 -
02:29
this is the bustling squatter city
48
149160
2000
这是熙熙攘攘的,寮屋搭建的基贝拉城
02:31
of Kibera, near Nairobi --
49
151160
4000
它靠近内罗毕 -
02:35
they see action. They see opportunity.
50
155160
2000
在城市,有活动,有机会。
02:37
They see a cash economy that they were not able to participate in
51
157160
3000
有现金经济交易,使得人们不愿回归到
02:40
back in the subsistence farm.
52
160160
3000
仅能维持生计的农业耕作上
02:43
As you go around these places there's plenty of aesthetics.
53
163160
2000
去到那些地方,你会发现很多美丽的景象
02:45
There is plenty going on.
54
165160
2000
还有很多事情发生。
02:47
They are poor, but they are intensely urban. And they are intensely creative.
55
167160
4000
他们是穷人,但他们高度城市化,而且他们有很强的创造性。
02:51
The aggregate numbers now
56
171160
2000
现在总人口数
02:53
are that basically squatters,
57
173160
3000
基本是住寮屋的人,
02:56
all one billion of them, are building the urban world,
58
176160
3000
他们中10亿人口正在建设他们的城市世界,
02:59
which means they're building the world --
59
179160
3000
也意味着他们正在建设新世界。
03:02
personally, one by one, family by family,
60
182160
2000
那是一种人与人的连结,一个接一个,一个家庭接一个家庭,
03:04
clan by clan, neighborhood by neighborhood.
61
184160
3000
家族联系着家族,左邻右舍的。
03:07
They start flimsy and they get substantial as time goes by.
62
187160
4000
他们开始举步维艰,随着时间的推移,他们取得实质性进展。
03:11
They even build their own infrastructure.
63
191160
2000
他们甚至建立起他们自己的基础设施。
03:13
Well, steal their own infrastructure, at first.
64
193160
3000
当然开始的时候是偷盗他们的基础设施,
03:16
Cable TV, water, the whole gamut, all gets stolen.
65
196160
3000
有线电视,水,整个范围,所有都被侵占,
03:19
And then gradually gentrifies.
66
199160
4000
然后逐渐修复改善。
03:23
It is not the case that slums undermine prosperity,
67
203160
3000
贫民窟破坏繁荣,情况实际不是这样。
03:26
not the working slums; they help create prosperity.
68
206160
4000
贫民窟的工作反而帮助创造繁荣。
03:30
So in a town like Mumbai, which is half slums,
69
210160
3000
孟买,这个城市有一半的城市贫民区,
03:33
it's 1/6th of the GDP of India.
70
213160
3000
但那里却创造了印度国内生产总值的六分之一。
03:36
Social capital in the slums is at its most urban and dense.
71
216160
5000
贫民窟的社会资本是高度城市化和最密集的。
03:41
These people are valuable as a group.
72
221160
3000
贫民窟里的人作为一个整体是最有价值的
03:44
And that's how they work.
73
224160
2000
这也正是他们的组织形式
03:46
There is a lot of people who think about all these poor people,
74
226160
3000
谈及贫民窟,很多人会想到
03:49
"Oh there's terrible things. We've got to fix their housing."
75
229160
2000
“哦,那里太糟糕了。我们必须解决他们的住房问题。”
03:51
It used to be, "Oh we've got to get them phone service."
76
231160
2000
还有“哦,我们得让他们有电话服务。”
03:53
Now they're showing us how they do their phone service.
77
233160
3000
现在,他们向我们展示他们是如何做电话服务的。
03:56
Famine mostly is a rural event now.
78
236160
2000
现在饥荒大多是农村的事情。
03:58
There are things they care about.
79
238160
2000
贫民窟的居民关心的是这些事情。
04:00
And this is where we can help.
80
240160
3000
而这正是我们可以帮助的方面。
04:03
And the nations they're in can help.
81
243160
2000
政府也可以提供帮助。
04:05
And they are helping each other solve these issues.
82
245160
3000
这样互相帮助,就可以解决类似问题。
04:08
And you go to a nice dense place like this slum in Mumbai.
83
248160
4000
你去一个像孟买这样的密集贫民区。
04:12
You look at that lane on the right.
84
252160
2000
你看关于右边的道路。
04:14
And you can ask, "Okay what's going on there?"
85
254160
2000
你会问:“那会发生什么?”
04:16
The answer is, "Everything."
86
256160
3000
答案是,“一切都在发生。”
04:19
This is better than a mall. It's much denser.
87
259160
3000
这比一个商场好得多。它的密度大的多。
04:22
It's much more interactive.
88
262160
2000
它更互动。
04:24
And the scale is terrific.
89
264160
2000
规模惊人。
04:26
The main event is, these are not people crushed by poverty.
90
266160
4000
关键是,人们不是被贫困折磨,
04:30
These are people busy getting out of poverty
91
270160
2000
而是人们忙于拼命要摆脱贫困
04:32
just as fast as they can.
92
272160
2000
尽他们所能,越快越好。
04:34
They're helping each other do it.
93
274160
2000
他们互相帮助做到这一点。
04:36
They're doing it through an outlaw thing,
94
276160
2000
他们通过非法去做的事情,
04:38
the informal economy.
95
278160
2000
称为非正规经济。
04:40
The informal economy, it's sort of like dark energy in astrophysics:
96
280160
4000
非正规经济,它好比在天体物理学里的暗能量。
04:44
it's not supposed to be there, but it's huge.
97
284160
2000
这本不应该有的,但它是巨大的。
04:46
We don't understand how it works yet, but we have to.
98
286160
3000
我们还不明白它是如何运作的。但我们必须理解。
04:49
Furthermore, people in the informal economy,
99
289160
2000
此外,非正规经济,
04:51
the gray economy --
100
291160
2000
或称灰色经济
04:53
as time goes by,
101
293160
2000
里头的人
04:55
crime is happening around them. And they can join the criminal world,
102
295160
4000
久而久之,也有可能走向犯罪。要么加入黑社会
04:59
or they can join the legitimate world.
103
299160
4000
要么进入正常的法治社会
05:03
We should be able to make that choice
104
303160
2000
我们应该可以帮助他们
05:05
easier for them to get toward the legitimate world,
105
305160
2000
使得她们更容易走进法治社会
05:07
because if we don't, they will go toward the criminal world.
106
307160
4000
因为如果我们不这样做,他们将成为黑社会的一员
05:11
There's all kinds of activity.
107
311160
3000
这会有多种活动影响。
05:14
In Dharavi the slum performs not only
108
314160
2000
在达拉维贫民窟不仅有
05:16
a lot of services for itself,
109
316160
2000
很多为自己的服务,
05:18
but it performs services for the city at large.
110
318160
3000
还为整个城市提供服务。
05:21
And one of the main events are these ad-hoc schools.
111
321160
3000
主要活动之一是这些特设学校。
05:24
Parents pool their money to hire some local teachers
112
324160
4000
家长集合钱去聘请一些地方教师
05:28
to a private, tiny, unofficial school.
113
328160
2000
到一所小的,私人的,非官方学校教书。
05:30
Education is more possible in the cities, and that changes the world.
114
330160
5000
在城市,教育是更有可能的,并改变了世界。
05:35
So you see some interesting, typical, urban things.
115
335160
3000
所以你看到一些有趣的,典型的,城市的东西。
05:38
So one thing slammed up against another,
116
338160
2000
贫民窟和富人区分别开来,
05:40
such as in Sao Paulo here.
117
340160
2000
例如在圣保罗这里。
05:42
That's what cities do. That's how they create value,
118
342160
2000
这就是城市所创造的价值,
05:44
is by slamming things together.
119
344160
2000
有机地融合起来。
05:46
In this case, supply right next to demand.
120
346160
2000
在这种情况下,供应需求紧密相连。
05:48
So the maids and the gardeners and the guards
121
348160
2000
就如,在这个城市左边,有着活生生的生活。
05:50
that live in this lively part of town on the left
122
350160
3000
这里生活的女佣、园丁和警卫人员
05:53
walk to work, in the boring, rich neighborhood.
123
353160
5000
步行到一个枯燥,富有的邻居家工作。
05:58
Proximity is amazing.
124
358160
3000
邻近性是惊人的。
06:01
We are learning about how dense proximity can be.
125
361160
3000
我们正在研究这密集邻近性。
06:16
Connectivity between the city and the country
126
376160
3000
城市和国家之间的邻近连接,
06:19
is what's going to keep the country good,
127
379160
3000
会使国家变好趋于完善。
06:22
because the city has interesting ways of doing things.
128
382160
3000
因为城市有很多有趣方法。
06:34
This is what makes cities --
129
394160
2000
这可以使城市--
06:36
(Applause)
130
396160
4000
(鼓掌)
06:40
this is what makes cities so green in the developing world.
131
400160
3000
这可以使发展中世界的城市变得更加绿色环保。
06:43
Because people leave the poverty trap, an ecological disaster
132
403160
3000
因为人们要摆脱贫困陷阱,一个赖以生存的农业生态灾难
06:46
of subsistence farms, and head to town.
133
406160
3000
而奔往城市。
06:49
And when they're gone the natural environment
134
409160
2000
而当他们离开农村后,自然环境
06:51
starts to come back very rapidly.
135
411160
2000
开始很快恢复。
06:53
And those who remain in the village can shift over to cash crops
136
413160
3000
而那些留在乡村的人则可以种植经济作物
06:56
to send food to the new growing markets in town.
137
416160
4000
并且将粮食卖到城市里去
07:00
So if you want to save a village, you do it with a good road,
138
420160
3000
所以,如果你想保留一个村庄,你得有良好的道路,
07:03
or with a good cell phone connection, and ideally some grid electrical power.
139
423160
4000
或有好的手机连接信号。最好配有一些电网电力。
07:07
So the event is: we're a city planet. That just happened.
140
427160
3000
我们都在地球城市生活。这情况转变
07:10
More than half.
141
430160
2000
已超过一半城市化。
07:12
The numbers are considerable. A billion live in the squatter cities now.
142
432160
3000
这些数字是相当大的。 现在10亿人生活在城市的寮屋。
07:15
Another billion is expected.
143
435160
3000
未来还将有10亿人要搬到城市
07:18
That's more than a sixth of humanity living a certain way.
144
438160
3000
这超过六分之一的人们以他们的方式生活着。
07:21
And that will determine a lot of how we function.
145
441160
4000
这将影响很大。
07:25
Now, for us environmentalists,
146
445160
2000
现在,对于我们这些环保主义者来说,
07:27
maybe the greenest thing about the cities is they diffuse the population bomb.
147
447160
3000
也许城市最环保的一点就是城市使得人口炸弹延迟引爆
07:30
People get into town.
148
450160
3000
人们进入城市。
07:33
The immediately have fewer children.
149
453160
2000
马上就想到不去生那么多孩子。
07:35
They don't even have to get rich yet. Just the opportunity of
150
455160
3000
他们甚至还没有富起来。要在城市求得生存
07:38
coming up in the world means they will have fewer, higher-quality kids,
151
458160
4000
就意味着少生优生
07:42
and the birthrate goes down radically.
152
462160
2000
出生率于是急剧下降
07:44
Very interesting side effect here,
153
464160
2000
还有其他有趣的副作用在发生
07:46
here's a slide from Phillip Longman.
154
466160
2000
这是菲利普朗曼的一个幻灯片,
07:48
Shows what is happening.
155
468160
2000
显示正在发生的事情。
07:50
As we have more and more old people, like me,
156
470160
2000
当我们有越来越多的老人和我一样,
07:52
and fewer and fewer babies.
157
472160
2000
越来越少的孩子出生。
07:54
And they are regionally separated.
158
474160
3000
它们是区域分开的。
07:57
What you're getting is a world which is
159
477160
2000
你会看到
07:59
old folks, and old cities, going around doing things the old way,
160
479160
5000
在北半球,都是些老人、老城市
08:04
in the north.
161
484160
2000
在按照传统的方式来生活
08:06
And young people in brand new cities they're inventing,
162
486160
3000
而在发展中世界的新兴城市,年轻人们在创新,
08:09
doing new things, in the south.
163
489160
2000
做些新鲜事情。
08:11
Where do you think the action is going to be?
164
491160
3000
你认为这些转变将在哪发生?
08:14
Shift of subject. Quickly drop by climate.
165
494160
3000
我要转移话题了。简单谈谈气候。
08:17
The climate news, I'm sorry to say, is going to keep getting worse
166
497160
2000
我很抱歉地说,气候的消息比我们想象的恶化得厉害,
08:19
than we think, faster than we think.
167
499160
3000
比我们所认为的变化快。
08:22
Climate is a profoundly complex, nonlinear system,
168
502160
2000
气候是深刻复杂的,非线性系统,
08:24
full of runaway positive feedbacks,
169
504160
3000
尽是失控的正反馈,
08:27
hidden thresholds and irrevocable tipping points.
170
507160
2000
隐藏的阈值和不可逆转的临界点。
08:29
Here's just a few samples.
171
509160
3000
这有些例子。
08:32
We're going to keep being surprised. And almost all
172
512160
2000
我们会很惊讶。几乎所有的
08:34
the surprises are going to be bad ones.
173
514160
2000
惊讶都是坏消息。
08:36
From your standpoint this means
174
516160
3000
从政府的立场来考虑,这意味着
08:39
a great increase in climate refugees
175
519160
2000
在未来几十年
08:41
over the coming decades,
176
521160
2000
气候移民将大幅增加
08:43
and what goes along with that, which is resource wars
177
523160
3000
随之而来的是资源的战争
08:46
and chaos wars,
178
526160
2000
和因为缺水而引发的战争
08:48
as we're seeing in Darfur.
179
528160
2000
就如我们在达尔富尔所看到的。
08:55
That's what drought does.
180
535160
2000
这就是干旱造成的战争。
08:57
It brings carrying capacity down,
181
537160
2000
承载能力随之下降。
08:59
and there's not enough carrying capacity
182
539160
2000
没有足够的承载能力
09:01
to support the people. And then you're in trouble.
183
541160
2000
支持该国人民。然后人们就有麻烦了。
09:04
Shift to the power situation.
184
544160
3000
好,我们再谈谈能源问题。
09:07
Baseload electricity is what it takes to run a city,
185
547160
3000
基荷电力是使得一个城市
09:10
or a city planet.
186
550160
2000
或一个城市星球运转。
09:12
So far there is only three sources of baseload electricity:
187
552160
4000
到目前为止,只有三种基荷电力资源,
09:16
coal, some gas,
188
556160
3000
煤炭来源,一些石油,
09:19
nuclear and hydro.
189
559160
2000
核能和水力发电。
09:21
Of those, only nuclear and hydro are green.
190
561160
4000
其中,仅核能和水力发电是绿色环保的。
09:25
Coal is what is causing the climate problems.
191
565160
2000
煤炭是造成气候问题的原因。
09:27
And everyone will keep burning it
192
567160
2000
因为它是如此便宜,除非政府提高燃煤发电的价格
09:29
because it's so cheap, until governments make it expensive.
193
569160
3000
否则每个人都会继续使用煤炭燃烧生电。
09:32
Wind and solar can't help, because so far we don't have a way to store that energy.
194
572160
5000
风能和太阳能帮助不大,因为到目前为止,我们没有办法存储这些能量。
09:37
So with hydro maxed out,
195
577160
3000
于是水力发电不能成为主要考虑的途径
09:40
coal and lose the climate,
196
580160
3000
用煤电就会破坏气候,
09:43
or nuclear, which is the current operating low-carbon source,
197
583160
3000
或者核能,这是当前可操作的低碳源,
09:46
and maybe save the climate.
198
586160
2000
或许可以拯救气候。
09:48
And if we can eventually get good solar in space,
199
588160
3000
如果我们最终可以很好的应用太阳能,
09:51
that also could help.
200
591160
2000
这也可以帮助。
09:53
Because remember, this is what drives the prosperity in the developing world
201
593160
5000
请记住,这可以推动发展中世界的乡村和城市
09:58
in the villages and in the cities.
202
598160
3000
走向繁荣
10:01
So, between coal and nuclear,
203
601160
2000
那么,就煤炭和核能之间,
10:03
compare their waste products.
204
603160
2000
比较它们的废弃物。
10:05
If all of the electricity you used in your lifetime was nuclear,
205
605160
4000
如果你一直都使用核能发电,
10:09
the amount of waste that would be added up
206
609160
2000
废弃物的数量加起来
10:11
would fit in a Coke can.
207
611160
3000
将等同于一罐可乐。
10:14
Whereas a coal-burning plant,
208
614160
2000
而一个燃煤电厂,
10:16
a normal one gigawatt coal plant, burns 80 rail cars of coal a day,
209
616160
4000
一个普通的,1千兆瓦的燃煤发电厂,每天燃烧80节煤炭轨道车。
10:20
each car having 100 tons.
210
620160
3000
每节车厢有100吨。
10:23
And it puts 18 thousand tons
211
623160
2000
它向空气中排放1.8万吨
10:25
of carbon dioxide in the air.
212
625160
4000
二氧化碳。
10:29
So and then when you compare the lifetime emissions
213
629160
2000
因此,当你就这些不同能源形式一生的排放量
10:31
of these various energy forms,
214
631160
2000
比较一下
10:33
nuclear is about even with solar and wind,
215
633160
2000
核电和太阳能和风能大致一样,
10:35
and ahead of solar --
216
635160
2000
核能还领先于太阳能。
10:37
oh, I'm sorry -- with hydro and wind, and ahead of solar.
217
637160
3000
噢,对不起。还有水电能和风能,领先于太阳能。
10:40
And does nuclear really compete with coal?
218
640160
2000
核电能可以和煤电能竞争吗?
10:42
Just ask the coal miners in Australia.
219
642160
2000
仅问问澳大利亚的煤矿工人就知道了。
10:44
That's where you see some of the source,
220
644160
2000
这就是你们所看到的资源信息,
10:46
not from my fellow environmentalists,
221
646160
2000
而不是从我的环保同事,
10:48
but from people who feel threatened by nuclear power.
222
648160
3000
而是从那些感受到核电威胁的矿工那得知。
10:51
Well the good news is that
223
651160
2000
那么好消息是,
10:53
the developing world, but frankly, the whole world,
224
653160
2000
发展中世界,坦率地说,整个世界,
10:55
is busy building, and starting to build, nuclear reactors.
225
655160
4000
是忙于建设,并开始建造核反应堆。
10:59
This is good for the atmosphere.
226
659160
2000
这利于大气,
11:01
It's good for their prosperity.
227
661160
2000
也利于繁荣。
11:03
I want to point out one interesting thing,
228
663160
2000
我想指出一个有趣的事情,
11:05
which is that environmentalists like the thing we call micropower.
229
665160
3000
那就是环保人士喜欢称之为微型反应堆的东西。
11:08
It's supposed to be, I don't know, local solar and wind and cogeneration,
230
668160
3000
我不太确定,据说是当地太阳能和风能和热电联供发电
11:11
and good things like that.
231
671160
2000
之类的东西。
11:13
But frankly micro-reactors which are just now coming on,
232
673160
2000
但坦率地说现在刚开始有的微型反应堆
11:15
might serve even better.
233
675160
2000
可能被更好地应用。
11:17
The Russians, who started this, are building floating reactors,
234
677160
2000
在俄国北部,那里的冰融化,有了新通道
11:19
for their new passage, where the ice is melting, north of Russia.
235
679160
4000
俄罗斯人开始在那建设浮动核反应堆
11:23
And they're selling these floating reactors,
236
683160
3000
他们向发展中国家卖这些
11:26
only 35 megawatts, to developing countries.
237
686160
4000
只有35兆瓦浮动核反应堆
11:30
Here's the design of an early one from Toshiba.
238
690160
2000
下面是东芝早期的设计。
11:32
It's interesting, say, to take a 25-megawatt,
239
692160
3000
这个很有趣,比如,它采取了25兆瓦,
11:35
25 million watts,
240
695160
2000
2千5百万瓦特,
11:37
and you compare it to the standard big iron
241
697160
2000
拿它和一般威斯汀豪斯或Ariva派的标准大铁块反应堆
11:39
of an ordinary Westinghouse or Ariva,
242
699160
4000
比较一下
11:43
which is 1.2, 1.6 billion watts.
243
703160
3000
它们通常是12亿到16亿瓦特
11:46
These things are way smaller. They're much more adaptable.
244
706160
4000
这些就小得多,并且非常容易安装
11:50
Here's an American design from Lawrence Livermore Lab.
245
710160
3000
这是美国劳伦斯利弗莫尔实验室的设计。
11:53
Here's another American design that came out
246
713160
2000
这还有美国洛斯阿拉莫斯国家实验室开始研制另一款设计,
11:55
of Los Alamos, and is now commercial.
247
715160
3000
现在它已经商业化。
11:58
Almost all of these are not only small, they are proliferation-proof.
248
718160
2000
几乎所有这些不仅仅是小,并且可以避免核扩散的发生
12:00
They're typically buried in the ground.
249
720160
3000
他们通常被埋在地下。
12:03
And the innovation is moving very rapidly.
250
723160
2000
创新发展非常迅速。
12:05
So I think microreactors is going to be important for the future.
251
725160
3000
所以我认为在未来微反应堆变得重要。
12:08
In terms of proliferation,
252
728160
2000
在核扩散方面,
12:10
nuclear energy has done more
253
730160
2000
核能发电事实上有助于核武器的消解
12:12
to dismantle nuclear weapons than any other activity.
254
732160
3000
其他办法都比不上这个
12:15
And that's why 10 percent of the electricity in this room,
255
735160
4000
这就是在这个会议室有百分之十
12:19
20 percent of electricity
256
739160
2000
甚至百分之二十的电力
12:21
in this room is probably nuclear.
257
741160
2000
可能是核电。
12:23
Half of that is coming from dismantled warheads from Russia,
258
743160
4000
其中一半是来自俄罗斯拆除的核弹头。
12:27
soon to be joined by our dismantled warheads.
259
747160
3000
不久也会有我们拆除的核弹头。
12:30
And so I would like to see the GNEP program,
260
750160
3000
我想看到布什政府积极推进的
12:33
that was developed in the Bush administration, go forward aggressively.
261
753160
3000
全球核能源合作计划能够继续推进
12:36
And I was glad to see that president Obama
262
756160
2000
我也很高兴看到奥巴马总统前几周
12:38
supported the nuclear fuel bank strategy
263
758160
3000
在布拉格讲到
12:41
when he spoke in Prague the other week.
264
761160
2000
他支持核燃料银行的战略
12:43
One more subject. Genetically engineered food crops,
265
763160
3000
再说另一个话题,就是转基因食品
12:46
in my view, as a biologist,
266
766160
2000
作为一个生物学家,以我的观点,
12:48
have no reason to be controversial.
267
768160
2000
转基因食品作物不会引起争议。
12:50
My fellow environmentalists, on this subject,
268
770160
2000
我的环保同行在这个问题上,
12:52
have been irrational, anti-scientific, and very harmful.
269
772160
4000
变得非理性,反科学的,那是十分有害的
12:56
Despite their best efforts,
270
776160
2000
尽管他们尽了最大努力,
12:58
genetically engineered crops are the most
271
778160
2000
转基因农作物是历史上
13:00
rapidly successful agricultural innovation in history.
272
780160
4000
最迅速发展成功的农业创新。
13:04
They're good for the environment because they enable no-till farming,
273
784160
3000
他们有利于环境的保护,因为它们免去了翻土的耕作
13:07
which leaves the soil in place,
274
787160
2000
使得土壤年复一年
13:09
getting healthier from year to year --
275
789160
2000
变得更加肥沃。
13:11
slso keeps less carbon dioxide going from the soil
276
791160
2000
也不断减少二氧化碳从土壤中排放
13:13
into the atmosphere.
277
793160
2000
到大气。
13:15
They reduce pesticide use.
278
795160
2000
它们减少了农药的使用,
13:17
And they increase yield, which allows you to have your
279
797160
2000
还增加产量
13:19
agricultural area be smaller,
280
799160
3000
在面积比较小的土地上就收获很多的粮食。
13:22
and therefore more wild area is freed up.
281
802160
3000
以致于让更多野外土地回归自然。
13:25
By the way, this map from 2006
282
805160
2000
顺便说一下,2006年这张地图
13:27
is out of date because it shows Africa
283
807160
2000
已经过时。但它显示
13:29
still under the thumb of Greenpeace,
284
809160
2000
受绿色和平组织
13:31
and Friends of the Earth from Europe,
285
811160
3000
和欧洲地球之友控制下的非洲。
13:34
and they're finally getting out from under that.
286
814160
2000
他们最终摆脱那些控制。
13:36
And biotech is moving rapidly in Africa, at last.
287
816160
3000
最后,生物技术正快速在非洲发展。
13:39
This is a moral issue.
288
819160
2000
这是一个道德问题。
13:41
The Nuffield Council on Bioethics
289
821160
2000
纳菲尔德生物伦理会议
13:43
met on this issue twice in great detail
290
823160
2000
就这个问题详细讨论,并召开两次会议,
13:45
and said it is a moral imperative
291
825160
2000
并表示这是一个道德责任,
13:47
to make genetically engineered crops readily available.
292
827160
3000
并使转基因作物随时可应用。
13:50
Speaking of imperatives, geoengineering is taboo now,
293
830160
3000
要讲到紧要事情,人工气候改造是一个禁忌话题
13:53
especially in government circles,
294
833160
2000
特别是在政府内部
13:55
though I think there was a DARPA meeting on it a couple of weeks ago,
295
835160
2000
但我知道就在几个星期前,美国国防高级研究规划局还为此开了一个会
13:57
but it will be on your plate --
296
837160
2000
但地球工程是事关你的事情,
13:59
not this year but pretty soon,
297
839160
3000
不是今年,但很快就会发生。
14:02
because some harsh realizations are coming along.
298
842160
3000
因为一些严峻的事实随之显现出来。
14:05
This is a list of them.
299
845160
2000
这是其中的一个清单。
14:07
Basically the news is going to keep getting more scary.
300
847160
3000
事实上所知的会越来越可怕。
14:10
There will be events,
301
850160
2000
将有一系列事件,
14:12
like 35,000 people dying of a heat wave,
302
852160
3000
如前阵子发生
14:15
which happened a while back.
303
855160
2000
35000人死于热浪
14:17
Like cyclones coming up toward Bangladesh.
304
857160
3000
又如袭击孟加拉国的龙卷风。
14:20
Like wars over water,
305
860160
2000
还有因为争夺水源而引发的战争
14:22
such as in the Indus.
306
862160
2000
例如印度河水患。
14:24
And as those events keep happening
307
864160
2000
由于这些事件不断发生,
14:26
we're going to say, "Okay, what can we do about that really?"
308
866160
2000
我们可能会说,“好吧,我们到底能做些什么呢?”
14:28
But there's this little problem with geoengineering:
309
868160
5000
但这是地球工程的小问题。
14:33
what body is going to decide
310
873160
4000
哪一个机构来做出决定
14:37
who gets to engineer? How much they do? Where they do it?
311
877160
2000
工程师是谁?他们做什么?他们在哪做?
14:39
Because everybody is downstream,
312
879160
2000
因为不管这一气候改造工程结果如何
14:41
downwind of whatever is done.
313
881160
3000
我们每个人到都将深受其影响
14:44
And if we just taboo it completely
314
884160
2000
如果我们要完全将此作为禁忌话题的话
14:46
we could lose civilization.
315
886160
2000
人类文明也有可能走向灭亡
14:48
But if we just say "OK,
316
888160
3000
但假如我们说,“好吧
14:51
China, you're worried, you go ahead.
317
891160
2000
中国,你要是担心的话,你先行动。
14:53
You geoengineer your way. We'll geoengineer our way."
318
893160
4000
你们的地球工程有你们的方式。我们有我们自己的。
14:57
That would be considered an act of war by both nations.
319
897160
3000
这就好比两国间的战争行为。
15:00
So this is very interesting diplomacy coming along.
320
900160
4000
接下来是非常有趣的外交对话。
15:04
I should say, it is more practical than people think.
321
904160
3000
但实际上要实现这样的工程比人们想象的要容易得多
15:07
Here is an example that climatologists like a lot,
322
907160
3000
气候学家很关注下面的例子。
15:10
one of the dozens of geoengineering ideas.
323
910160
2000
许多地球工程点子中的一个,
15:12
This one came from the sulfur dioxide
324
912160
2000
1991年,皮纳图博火山喷发,
15:14
from Mount Pinatubo in 1991 --
325
914160
3000
所喷出的二氧化硫
15:17
cooled the earth by half a degree.
326
917160
4000
使得地球的温度降低了摄氏半度。
15:21
There was so much ice in 1992, the following year,
327
921160
2000
第二年1992年,很多的冰
15:23
that there was a bumper crop of polar bear cubs
328
923160
3000
才使北极熊幼仔丰产,
15:26
who were known as the Pinatubo cubs.
329
926160
2000
它们取名皮纳图博北极熊宝宝。
15:28
To put sulfur dioxide in the stratosphere
330
928160
2000
向平流层中排放二氧化硫
15:30
would cost on the order of a billion dollars a year.
331
930160
3000
每年将花费10亿美元成本
15:33
That's nothing, compared to all of the other
332
933160
3000
相对于我们有关能源可能要做的所有事情,
15:36
things we may be trying to do about energy.
333
936160
2000
这真不算什么。
15:38
Just to run by another one:
334
938160
3000
另一个应用的例子
15:41
this is a plan to brighten the reflectance of ocean clouds,
335
941160
3000
计划是靠雾化海水
15:44
by atomizing seawater;
336
944160
2000
使海洋云层反射更加活跃
15:46
that would brighten the albedo of the whole planet.
337
946160
2000
这将影响整个地球的反照率。
15:48
A nice one, because it can happen
338
948160
2000
因为它可以
15:50
lots of little ways in lots of little places,
339
950160
2000
在许多很小的地方以很多不同方式发生
15:52
is by copying the ancient Amazon Indians
340
952160
2000
一个好例子是仿照古代亚马逊印第安人
15:54
who made good agricultural soil
341
954160
2000
通过热分解,不完全燃烧,植物废料
15:56
by pyrolizing, smoldering, plant waste,
342
956160
4000
使农业土壤更肥沃
16:00
and biochar fixes large quantities of carbon
343
960160
3000
生物炭替代大量的碳
16:03
while it's improving the soil.
344
963160
2000
从而改善土壤。
16:05
So here is where we are.
345
965160
3000
这是我们的准则。
16:08
Nobel Prize-winning climatologist Paul Crutzen
346
968160
3000
诺贝尔奖得主气候学家保罗·克鲁岑
16:11
calls our geological era the Anthropocene,
347
971160
3000
把我们现今这个地质时代称为人类世
16:14
the human-dominated era. We are stuck
348
974160
3000
也就是说现在人类活动正在改变着地球的面貌
16:17
with its obligations.
349
977160
3000
并且我们还将不得不继续完成这样的任务
16:20
In the Whole Earth Catalog, my first words were,
350
980160
2000
在《地球目录》的第一句话是
16:22
"We are as Gods, and might as well get good at it."
351
982160
2000
“我们就像上帝一样,也许我们可以做好这个角色。”
16:24
The first words of Whole Earth Discipline
352
984160
3000
而《地球的法则》的第一句话是:
16:27
are, "We are as Gods, and have to get good at it."
353
987160
4000
“我们就是上帝,我们必须做好这个角色。”
16:31
Thank you.
354
991160
2000
谢谢。
16:33
(Applause)
355
993160
4000
(鼓掌)
