Čovjek koji je pomogao rasprostranjenju ekološkog pokreta tijekom 1960ih i 1970ih godina ponovno promišljao o svom stavu o gradovima, nuklearnim centralama, genetičkim modifikacijama i geo-inženjeringu. Ovaj govor pred američkim Ministarstvom vanjskih poslova najava je njegove nove knjige koja će sigurno izazvati široku raspravu.

Because of what I'm about to say,
0
0
2000
Zbog onoga što namjeravam izreći,
00:18
I really should establish my green credentials.
1
2000
3000
stvarno vam moram dokazati svoja zelena uvjerenja.
00:21
When I was a small boy, I took my pledge
2
5000
2000
Kad sam bio maleni dječak, obavezao sam se
00:23
as an American, to save and faithfully defend from waste
3
7000
3000
kao Amerikanac čuvati i vjerno braniti od pustošenja
00:26
the natural resources of my country,
4
10000
2000
prirodne resurse svoje zemlje.
00:28
its air, soil and minerals, its forests, waters and wildlife.
5
12000
3000
Njen zrak, tlo i minerale, njene šume, vode i divljinu.
00:31
And I've stuck to that.
6
15000
2000
I na tome sam zaglavio.
00:33
Stanford, I majored in ecology and evolution.
7
17000
4000
Stanford, diplomirao sam ekologiju i evoluciju.
00:37
1968, I put out the Whole Earth Catalog. Was "mister natural" for a while.
8
21000
4000
1968. godine izdao sam "Katalog cijele Zemlje". Neko vrijeme bio sam "mister prirode".
00:41
And then worked for the Jerry Brown administration.
9
25000
3000
Onda sam radio za administraciju Jerryja Browna,
00:44
The Brown administration, and a bunch of my friends,
10
28000
3000
te sam s grupom prijatelja
00:47
basically leveled the energy efficiency of California,
11
31000
3000
zapravo ujednačio energetsku efikasnost Kalifornije.
00:50
so it's the same now, 30 years later,
12
34000
3000
Stoga je danas ista kao i prije trideset godina.
00:53
even though our economy has gone up 80 percent, per capita.
13
37000
4000
Iako je u međuvremenu naša ekonomija narasla za 80% po glavi stanovnika,
00:57
And we are putting out less greenhouse gasses than any other state.
14
41000
3000
Mi izbacujemo manje stakleničkih plinova nego ijedna druga država.
01:00
California is basically the equivalent of Europe, in this.
15
44000
3000
Kalifornija je u biti jednaka Europi, po tome.
01:03
This year, Whole Earth Catalog has a supplement that I'll preview today,
16
47000
5000
Ove godine, "Katalog cijele Zemlje" ima dodatak kojega danas prikazujem,
01:08
called Whole Earth Discipline.
17
52000
3000
nazvan "Disciplina cijele Zemlje".
01:11
The dominant demographic event of our time
18
55000
2000
Dominantni demografski događaj našega doba
01:13
is this screamingly rapid urbanization
19
57000
3000
je strahovito ubrzana urbanizacija
01:16
that we have going on.
20
60000
2000
u kojoj se sada nalazimo.
01:18
By mid-century we'll be about 80 percent urban,
21
62000
4000
Do sredine stoljeća biti ćemo oko 80% urbani.
01:22
and that's mostly in the developing world,
22
66000
3000
I to većinom u zemljama u razvoju,
01:25
where that's happening.
23
69000
2000
gdje se ovo događa.
01:27
It's interesting, because history is driven to a large degree
24
71000
3000
To je zanimljivo. Zato što u velikoj mjeri
01:30
by the size of cities.
25
74000
2000
veličina gradova pokreće povijest.
01:32
The developing world now has all of the biggest cities,
26
76000
3000
Zemlje u razvoju sada imaju sve najveće gradove.
01:35
and they are developing three times faster than the developed countries,
27
79000
3000
I one se razvijaju tri puta brže od razvijenih zemalja.
01:38
and nine times bigger.
28
82000
2000
I devet puta su veći.
01:40
It's qualitatively different.
29
84000
3000
To je kvalitativna razlika.
01:43
They are the drivers of history, as we see by looking at history.
30
87000
2000
One su pokretači povijesti, a to vidimo promatrajući povijest.
01:45
1,000 years ago this is what the world looked like.
31
89000
4000
Prije 1.000 godina svijet je izgledao ovako.
01:49
Well we now have a distribution of urban power
32
93000
3000
Sada imamo raspodjelu urbanih sila
01:52
similar to what we had 1,000 years ago.
33
96000
3000
sličnu onoj prije 1.000 godina.
01:55
In other words, the rise of the West,
34
99000
2000
Drugim riječima, uspon Zapada,
01:57
dramatic as it was, is over.
35
101000
4000
dramatičan kakav je bio, završen je.
02:01
The aggregate numbers are absolutely overwhelming:
36
105000
3000
Zbirne brojke apsolutno su moćne.
02:04
1.3 million people a week coming to town,
37
108000
3000
1.3 milijuna ljudi tjedno dolazilo je u grad,
02:07
decade after decade.
38
111000
2000
desetljeće za desetljećem.
02:09
What's really going on?
39
113000
2000
Što se ustvari događa?
02:11
Well, what's going on is the villages of the world are emptying out.
40
115000
3000
Dakle, događa se pražnjenje sela širom svijeta.
02:14
Subsistence farming is drying up basically.
41
118000
3000
U suštini presušuje poljodjelstvo namijenjeno prehrani vlastite obitelji.
02:17
People are following opportunity into town.
42
121000
2000
Ljudi slijede povoljne prilike u gradove.
02:19
And this is why.
43
123000
2000
A evo zašto.
02:21
I used to have a very romantic idea about villages,
44
125000
2000
Nekada sam imao vrlo romantične ideje o selu
02:23
and it's because I never lived in one.
45
127000
3000
a to je zato što nikad nisam živio u nekom.
02:26
(Laughter)
46
130000
1000
(Smijeh)
02:27
Because in town --
47
131000
2000
Zato što u gradu –
02:29
this is the bustling squatter city
48
133000
2000
ovo je bučni ilegalni grad
02:31
of Kibera, near Nairobi --
49
135000
4000
Kibera, u blizini Nairobia.
02:35
they see action. They see opportunity.
50
139000
2000
Oni vide akciju. Oni vide mogućnosti.
02:37
They see a cash economy that they were not able to participate in
51
141000
3000
Oni vide monetarnu ekonomiju u kojoj nisu bili sposobni sudjelovati
02:40
back in the subsistence farm.
52
144000
3000
iz pozadine samoprehranjujućih farmi.
02:43
As you go around these places there's plenty of aesthetics.
53
147000
2000
Kada se prošećete po tim mjestima evidentno je obilje estetike.
02:45
There is plenty going on.
54
149000
2000
Svašta se događa.
02:47
They are poor, but they are intensely urban. And they are intensely creative.
55
151000
4000
Oni su siromašni, ali su intenzivno urbani. I intenzivno su kreativni.
02:51
The aggregate numbers now
56
155000
2000
Zbirne brojke govore kako
02:53
are that basically squatters,
57
157000
3000
u osnovi ilegalci,
02:56
all one billion of them, are building the urban world,
58
160000
3000
milijarda njih, grade urbani svijet.
02:59
which means they're building the world --
59
163000
3000
Ovo znači da oni zidaju urbani svijet.
03:02
personally, one by one, family by family,
60
166000
2000
Osobno, jedan po jedan, obitelj po obitelj,
03:04
clan by clan, neighborhood by neighborhood.
61
168000
3000
klan za klanom, susjedstvo za susjedstvom.
03:07
They start flimsy and they get substantial as time goes by.
62
171000
4000
Započnu neprimjetno i postanu značajni kako vrijeme prolazi.
03:11
They even build their own infrastructure.
63
175000
2000
Oni čak grade vlastitu infrastrukturu.
03:13
Well, steal their own infrastructure, at first.
64
177000
3000
Ustvari, ukradu vlastitu infrastrukturu, u početku.
03:16
Cable TV, water, the whole gamut, all gets stolen.
65
180000
3000
Kablovsku TV, vodu, cijela skala, sve ukradeno.
03:19
And then gradually gentrifies.
66
183000
4000
A onda polako postaju srednja klasa.
03:23
It is not the case that slums undermine prosperity,
67
187000
3000
U stvari slamovi ne potkopavaju prosperitet.
03:26
not the working slums; they help create prosperity.
68
190000
4000
Neradnički slamovi, oni pomažu stvoriti ga.
03:30
So in a town like Mumbai, which is half slums,
69
194000
3000
Tako gradovi poput Mumbaia, čiju polovinu čine slamovi,
03:33
it's 1/6th of the GDP of India.
70
197000
3000
predstavlja 1/6 BDP-a Indije.
03:36
Social capital in the slums is at its most urban and dense.
71
200000
5000
Socijalni kapital tih slamova je najurbaniji i najgušći.
03:41
These people are valuable as a group.
72
205000
3000
Ti su ljudi dragocjeni kao grupa.
03:44
And that's how they work.
73
208000
2000
I tako oni djeluju.
03:46
There is a lot of people who think about all these poor people,
74
210000
3000
Mnogo je ljudi koji razmišljaju o svim tim siromašnim ljudima.
03:49
"Oh there's terrible things. We've got to fix their housing."
75
213000
2000
"O, to je strašno. Moramo srediti njihovo stanovanje."
03:51
It used to be, "Oh we've got to get them phone service."
76
215000
2000
Nekad je bilo: "O moramo im riješiti telefonske instalacije."
03:53
Now they're showing us how they do their phone service.
77
217000
3000
Sad oni pokazuju nama kako se rade telefonske usluge.
03:56
Famine mostly is a rural event now.
78
220000
2000
Oskudica je danas uglavnom ruralno događanje.
03:58
There are things they care about.
79
222000
2000
Postoje stvari do kojih im je stalo.
04:00
And this is where we can help.
80
224000
3000
I to je ono u čemu mi možemo pomoći.
04:03
And the nations they're in can help.
81
227000
2000
I nacije u kojima oni jesu mogu pomoći.
04:05
And they are helping each other solve these issues.
82
229000
3000
I oni pomažu jedni drugima riješiti ovu problematiku.
04:08
And you go to a nice dense place like this slum in Mumbai.
83
232000
4000
I onda odete u krasno gusto naseljeno mjesto kakav je ovaj slam u Mumbaiju.
04:12
You look at that lane on the right.
84
236000
2000
Pogledajte onaj red na desno.
04:14
And you can ask, "Okay what's going on there?"
85
238000
2000
I možete pitati: "No dobro što se tamo događa?“
04:16
The answer is, "Everything."
86
240000
3000
Odgovor je: "Sve."
04:19
This is better than a mall. It's much denser.
87
243000
3000
To je bolje od šoping centra. Mnogo je gušće.
04:22
It's much more interactive.
88
246000
2000
Više je interaktivno.
04:24
And the scale is terrific.
89
248000
2000
A raspon je nevjerojatan.
04:26
The main event is, these are not people crushed by poverty.
90
250000
4000
Glavni događaj je, ovo nisu ljudi shrvani siromaštvom.
04:30
These are people busy getting out of poverty
91
254000
2000
Ovo su ljudi zaposleni izlaženjem iz siromaštva
04:32
just as fast as they can.
92
256000
2000
onoliko brzo koliko se može.
04:34
They're helping each other do it.
93
258000
2000
Oni pomažu jedni drugima učiniti to.
04:36
They're doing it through an outlaw thing,
94
260000
2000
Čine to protuzakonito,
04:38
the informal economy.
95
262000
2000
neformalnom ekonomijom.
04:40
The informal economy, it's sort of like dark energy in astrophysics:
96
264000
4000
neformalnoj ekonomiji je nešto kao tamna energija u astrofizici.
04:44
it's not supposed to be there, but it's huge.
97
268000
2000
Ne bi trebala biti tamo, ali je ogromna.
04:46
We don't understand how it works yet, but we have to.
98
270000
3000
Još ne razumijemo kako funkcionira. Ali morat ćemo.
04:49
Furthermore, people in the informal economy,
99
273000
2000
Nadalje, ljudi u neformalnoj ekonomiji,
04:51
the gray economy --
100
275000
2000
sivoj ekonomiji,
04:53
as time goes by,
101
277000
2000
kako vrijeme prolazi,
04:55
crime is happening around them. And they can join the criminal world,
102
279000
4000
kriminal se događa oko njih. I oni se mogu pridružiti svijetu kriminala.
04:59
or they can join the legitimate world.
103
283000
4000
Ili se mogu pridružiti legitimnom svijetu.
05:03
We should be able to make that choice
104
287000
2000
Mi bismo trebali biti u stanju učiniti im izbor
05:05
easier for them to get toward the legitimate world,
105
289000
2000
prema legitimnom svijetu lakšim.
05:07
because if we don't, they will go toward the criminal world.
106
291000
4000
Zato što će u suprotnom otići prema svijetu kriminala.
05:11
There's all kinds of activity.
107
295000
3000
Postoje sve moguće vrste aktivnosti.
05:14
In Dharavi the slum performs not only
108
298000
2000
U Dharavi slamovi rade ne samo
05:16
a lot of services for itself,
109
300000
2000
puno uslužnih djelatnosti sebi samima,
05:18
but it performs services for the city at large.
110
302000
3000
nego i gradu u cjelini.
05:21
And one of the main events are these ad-hoc schools.
111
305000
3000
A jedno od glavnih događanja su te ad hoc škole.
05:24
Parents pool their money to hire some local teachers
112
308000
4000
Roditelji sakupe svoj novac kako bi zaposlili lokalne učitelje
05:28
to a private, tiny, unofficial school.
113
312000
2000
za privatne, malene, neslužbene škole.
05:30
Education is more possible in the cities, and that changes the world.
114
314000
5000
Za edukaciju ima više mogućnosti u gradovima. A to mijenja svijet.
05:35
So you see some interesting, typical, urban things.
115
319000
3000
I sad vidite neke zanimljive, tipično urbane stvari.
05:38
So one thing slammed up against another,
116
322000
2000
I tako se stvari sudaraju jedna s drugom,
05:40
such as in Sao Paulo here.
117
324000
2000
kao što je to ovdje u Sao Paulu.
05:42
That's what cities do. That's how they create value,
118
326000
2000
To je ono što rade gradovi. Tako oni stvaraju dobit,
05:44
is by slamming things together.
119
328000
2000
sudaranjem stvari jednih o druge.
05:46
In this case, supply right next to demand.
120
330000
2000
U ovom slučaju, ponuda odmah pored potražnje.
05:48
So the maids and the gardeners and the guards
121
332000
2000
Kao i služavke i vrtlari i čuvari
05:50
that live in this lively part of town on the left
122
334000
3000
koji žive u ovom živopisnom dijelu grada na lijevoj
05:53
walk to work, in the boring, rich neighborhood.
123
337000
5000
stazi prema poslu, u dosadnom, bogatom susjedstvu.
05:58
Proximity is amazing.
124
342000
3000
Blizina je fantastična.
06:01
We are learning about how dense proximity can be.
125
345000
3000
Upravo učimo koliko gusta može biti blizina.
06:16
Connectivity between the city and the country
126
360000
3000
Povezanost između grada i pokrajine
06:19
is what's going to keep the country good,
127
363000
3000
je ono što će pokrajinu učiniti dobrom.
06:22
because the city has interesting ways of doing things.
128
366000
3000
Zato što grad ima zanimljive načine obavljanja stvari.
06:34
This is what makes cities --
129
378000
2000
To je ono što stvara gradove -
06:36
(Applause)
130
380000
4000
(Pljesak)
06:40
this is what makes cities so green in the developing world.
131
384000
3000
Ovo je to što gradove čini tako zelenima u zemljama u razvoju.
06:43
Because people leave the poverty trap, an ecological disaster
132
387000
3000
Zato što ljudi napuštaju zamku siromaštva, ekološku propast
06:46
of subsistence farms, and head to town.
133
390000
3000
poljodjelstva za vlastite potrebe i žure u grad.
06:49
And when they're gone the natural environment
134
393000
2000
A kada odu prirodni okoliš se jako
06:51
starts to come back very rapidly.
135
395000
2000
brzo oporavlja.
06:53
And those who remain in the village can shift over to cash crops
136
397000
3000
A oni koji su ostali u selu mogu se prebaciti na urode kojima se zarađuje
06:56
to send food to the new growing markets in town.
137
400000
4000
i slati hranu na nove, rastuće tržnice u gradu.
07:00
So if you want to save a village, you do it with a good road,
138
404000
3000
I zato ako želite spasiti sela, napravite to sa dobrim cestama
07:03
or with a good cell phone connection, and ideally some grid electrical power.
139
407000
4000
ili sa dobrim telefonskim vezama. A idealno bi bilo i nešto električne mreže.
07:07
So the event is: we're a city planet. That just happened.
140
411000
3000
I tako se događa, mi smo planet gradova. To se samo dogodilo.
07:10
More than half.
141
414000
2000
Više od polovice.
07:12
The numbers are considerable. A billion live in the squatter cities now.
142
416000
3000
Brojke su ogromne. Milijarda ljudi danas živi u ilegalnim gradovima.
07:15
Another billion is expected.
143
419000
3000
Druga se očekuje.
07:18
That's more than a sixth of humanity living a certain way.
144
422000
3000
Više od jedne šestine čovječanstva živi na ovaj način.
07:21
And that will determine a lot of how we function.
145
425000
4000
A ovo će odrediti većinu toga kako ćemo funkcionirati.
07:25
Now, for us environmentalists,
146
429000
2000
Sada, za nas zaštitare okoliša,
07:27
maybe the greenest thing about the cities is they diffuse the population bomb.
147
431000
3000
možda je najzelenija stvar oko gradova raspršenje populacijske bombe.
07:30
People get into town.
148
434000
3000
Ljudi dođu u grad.
07:33
The immediately have fewer children.
149
437000
2000
Odmah imaju manje djece.
07:35
They don't even have to get rich yet. Just the opportunity of
150
439000
3000
Čak se ne moraju još niti obogatiti. Sama prilika da se
07:38
coming up in the world means they will have fewer, higher-quality kids,
151
442000
4000
iziđe u svijet već znači da će imati manje visoko-kvalitetne djece,
07:42
and the birthrate goes down radically.
152
446000
2000
a natalitet drastično pada.
07:44
Very interesting side effect here,
153
448000
2000
Vrlo zanimljiva nuspojava,
07:46
here's a slide from Phillip Longman.
154
450000
2000
ovo je slajd Phillip Longmana.
07:48
Shows what is happening.
155
452000
2000
Pokazuje što se događa.
07:50
As we have more and more old people, like me,
156
454000
2000
Kako imamo sve više starih ljudi, poput mene,
07:52
and fewer and fewer babies.
157
456000
2000
i sve manje i manje djece.
07:54
And they are regionally separated.
158
458000
3000
A oni su i regionalno odijeljeni.
07:57
What you're getting is a world which is
159
461000
2000
Ono što sada vidite je svijet
07:59
old folks, and old cities, going around doing things the old way,
160
463000
5000
starih ljudi, i starih gradova, koji se šeću uokolo i rade stvari na stari način,
08:04
in the north.
161
468000
2000
na sjeveru.
08:06
And young people in brand new cities they're inventing,
162
470000
3000
I mladi ljudi u sasvim novim gradovima koji investiraju,
08:09
doing new things, in the south.
163
473000
2000
rade nove stvari, na jugu.
08:11
Where do you think the action is going to be?
164
475000
3000
Što vam se čini gdje će biti akcije?
08:14
Shift of subject. Quickly drop by climate.
165
478000
3000
Promijenimo temu. Brzo prijeđimo na klimu.
08:17
The climate news, I'm sorry to say, is going to keep getting worse
166
481000
2000
Vijesti će o klimi, žao mi je to reći, pogoršavati
08:19
than we think, faster than we think.
167
483000
3000
više nego što mislimo, brže nego što mislimo.
08:22
Climate is a profoundly complex, nonlinear system,
168
486000
2000
Klima je duboko kompleksan, nelinearni sustav,
08:24
full of runaway positive feedbacks,
169
488000
3000
pun povratnih veza koje ne podliježu kontroli,
08:27
hidden thresholds and irrevocable tipping points.
170
491000
2000
skrivenih graničnih i neopozivih točaka preokreta.
08:29
Here's just a few samples.
171
493000
3000
Evo samo nekoliko primjera.
08:32
We're going to keep being surprised. And almost all
172
496000
2000
Mi se nastavljamo iznenađivati. I gotovo sva ta
08:34
the surprises are going to be bad ones.
173
498000
2000
iznenađenja će biti loša.
08:36
From your standpoint this means
174
500000
3000
S vaše točke gledišta ovo znači
08:39
a great increase in climate refugees
175
503000
2000
veliko povećanje klimatskih izbjeglica
08:41
over the coming decades,
176
505000
2000
u narednim desetljećima.
08:43
and what goes along with that, which is resource wars
177
507000
3000
A ono što ide s tim, izvorište ratova i
08:46
and chaos wars,
178
510000
2000
kaosa ratova,
08:48
as we're seeing in Darfur.
179
512000
2000
kao što to vidimo u Darfuru.
08:55
That's what drought does.
180
519000
2000
To je ono što čini suša.
08:57
It brings carrying capacity down,
181
521000
2000
Spušta kapacitet opstanka.
08:59
and there's not enough carrying capacity
182
523000
2000
A ovdje nema dovoljno kapaciteta opstanka
09:01
to support the people. And then you're in trouble.
183
525000
2000
da bi podržao te ljude. I onda ste u nevolji.
09:04
Shift to the power situation.
184
528000
3000
Prijeđimo na situaciju s energijom.
09:07
Baseload electricity is what it takes to run a city,
185
531000
3000
Pogon osnovnog opterećenje električnog sustava pokreće gradove,
09:10
or a city planet.
186
534000
2000
odnosno planet gradova.
09:12
So far there is only three sources of baseload electricity:
187
536000
4000
Za sada postoje samo tri izvora pogona električnog sustava –
09:16
coal, some gas,
188
540000
3000
ugljen, neki plinovi,
09:19
nuclear and hydro.
189
543000
2000
nuklearna i hidroenergija.
09:21
Of those, only nuclear and hydro are green.
190
545000
4000
Od ovih, samo su nuklearna i hidroenergija zelene.
09:25
Coal is what is causing the climate problems.
191
549000
2000
Ugljen je ono što izaziva klimatološke probleme.
09:27
And everyone will keep burning it
192
551000
2000
I svi će ga nastaviti sagorijevati
09:29
because it's so cheap, until governments make it expensive.
193
553000
3000
jer je tako jeftin, sve dok ga vlade ne učine skupim.
09:32
Wind and solar can't help, because so far we don't have a way to store that energy.
194
556000
5000
Vjetar i solarna energija ne mogu pomoći jer za sada nemamo načina da uskladištimo tu energiju.
09:37
So with hydro maxed out,
195
561000
3000
Tako možemo s hidroenergijom podignutom do maksimuma
09:40
coal and lose the climate,
196
564000
3000
i ugljenom, izgubiti klimu,
09:43
or nuclear, which is the current operating low-carbon source,
197
567000
3000
ili nuklearnom, što je trenutačni operativni nisko-ugljični izvor,
09:46
and maybe save the climate.
198
570000
2000
možda spasiti klimu.
09:48
And if we can eventually get good solar in space,
199
572000
3000
I ako bi smo na kraju dobili dobar solarni pogon,
09:51
that also could help.
200
575000
2000
to bi moglo pomoći.
09:53
Because remember, this is what drives the prosperity in the developing world
201
577000
5000
Zato što, sjetite se, to je ono što pokreće prosperitet u zemljama u razvoju,
09:58
in the villages and in the cities.
202
582000
3000
u selima i gradovima.
10:01
So, between coal and nuclear,
203
585000
2000
Tako, između ugljena i nuklearne energije,
10:03
compare their waste products.
204
587000
2000
usporedimo njihove otpadne produkte.
10:05
If all of the electricity you used in your lifetime was nuclear,
205
589000
4000
Da je sva struja koju ste koristili u svom životu proizvedena u nuklearki,
10:09
the amount of waste that would be added up
206
593000
2000
količina smeća koju bi pridonijeli
10:11
would fit in a Coke can.
207
595000
3000
stala bi u limenku Cole.
10:14
Whereas a coal-burning plant,
208
598000
2000
Dok centrala na ugljen,
10:16
a normal one gigawatt coal plant, burns 80 rail cars of coal a day,
209
600000
4000
jedna normalna od elektrana od gigawata, sagorijeva 80 vagona ugljena dnevno.
10:20
each car having 100 tons.
210
604000
3000
Svaki vagon teži 100 tona.
10:23
And it puts 18 thousand tons
211
607000
2000
A izbacuje 18 tisuća tona
10:25
of carbon dioxide in the air.
212
609000
4000
ugljičnog dioksida u zrak.
10:29
So and then when you compare the lifetime emissions
213
613000
2000
I tako kad usporedite emisiju
10:31
of these various energy forms,
214
615000
2000
iz različitih formi energije tijekom vijeka trajanja,
10:33
nuclear is about even with solar and wind,
215
617000
2000
nuklearna je otprilike jednaka vjetru i solarnoj.
10:35
and ahead of solar --
216
619000
2000
I ispred solarne.
10:37
oh, I'm sorry -- with hydro and wind, and ahead of solar.
217
621000
3000
O, oprostite. S vodom i vjetrom, a ispred solarne.
10:40
And does nuclear really compete with coal?
218
624000
2000
Konkurira li nuklearna energija ugljenu?
10:42
Just ask the coal miners in Australia.
219
626000
2000
Samo pitajte rudare u Australiji.
10:44
That's where you see some of the source,
220
628000
2000
Tamo ćete biti na izvorištu,
10:46
not from my fellow environmentalists,
221
630000
2000
ne kod mojih kolega ekologa,
10:48
but from people who feel threatened by nuclear power.
222
632000
3000
nego kod ljudi koji se osjećaju ugroženi nuklearnom energijom.
10:51
Well the good news is that
223
635000
2000
No dobra je vijest da
10:53
the developing world, but frankly, the whole world,
224
637000
2000
su zemlje u razvoju, ma ustvari cijeli svijet,
10:55
is busy building, and starting to build, nuclear reactors.
225
639000
4000
zaposleni gradnjom ili počinju graditi, nuklearne reaktore.
10:59
This is good for the atmosphere.
226
643000
2000
To je dobro za atmosferu.
11:01
It's good for their prosperity.
227
645000
2000
To je dobro za njihov prosperitet.
11:03
I want to point out one interesting thing,
228
647000
2000
Želim naglasiti jednu zanimljivu stvar,
11:05
which is that environmentalists like the thing we call micropower.
229
649000
3000
a to je da ekolozi vole stvar koju nazivamo mikrocentrala.
11:08
It's supposed to be, I don't know, local solar and wind and cogeneration,
230
652000
3000
To bi trebala biti, ne znam, lokalna solarna energija plus vjetar i kogeneracija
11:11
and good things like that.
231
655000
2000
to dvoje i druge dobre stvari poput toga.
11:13
But frankly micro-reactors which are just now coming on,
232
657000
2000
No iskreno mikro-reaktori koji upravo dolaze,
11:15
might serve even better.
233
659000
2000
mogu poslužiti još bolje.
11:17
The Russians, who started this, are building floating reactors,
234
661000
2000
Rusi, koji su krenuli s tim, grade ploveće reaktore
11:19
for their new passage, where the ice is melting, north of Russia.
235
663000
4000
za svoje nove prolaze tamo gdje se topi led, sjeverno od Rusije.
11:23
And they're selling these floating reactors,
236
667000
3000
A oni i prodaju te ploveće reaktore,
11:26
only 35 megawatts, to developing countries.
237
670000
4000
samo 35 megavata, zemljama u razvoju.
11:30
Here's the design of an early one from Toshiba.
238
674000
2000
Ovo je dizajn jedne rane od Toshibe.
11:32
It's interesting, say, to take a 25-megawatt,
239
676000
3000
Zanimljivo, uzmimo recimo 25 megavata,
11:35
25 million watts,
240
679000
2000
25 milijuna vata,
11:37
and you compare it to the standard big iron
241
681000
2000
i usporedimo to sa standardnim velikim željeznim reaktorom
11:39
of an ordinary Westinghouse or Ariva,
242
683000
4000
obično od Westinghouse ili Ariva,
11:43
which is 1.2, 1.6 billion watts.
243
687000
3000
koji je 1.2, 1.6 milijardi vata.
11:46
These things are way smaller. They're much more adaptable.
244
690000
4000
Te su stvari red veličine manje. One su mnogo prilagodljivije.
11:50
Here's an American design from Lawrence Livermore Lab.
245
694000
3000
Ovdje je jedan američki dizajn od Lawrence Livermore Lab.
11:53
Here's another American design that came out
246
697000
2000
Ovdje je još jedan američki dizajn koji dolazi
11:55
of Los Alamos, and is now commercial.
247
699000
3000
iz Los Alamosa, i sada je komercijalan.
11:58
Almost all of these are not only small, they are proliferation-proof.
248
702000
2000
Gotovo svi oni nisu samo mali, nego su i zaštićeni od širenja.
12:00
They're typically buried in the ground.
249
704000
3000
Obično su ukopani u zemlju.
12:03
And the innovation is moving very rapidly.
250
707000
2000
A inovacije brzo napreduju.
12:05
So I think microreactors is going to be important for the future.
251
709000
3000
Tako ja mislim kako će mikroreaktori biti važni za budućnost.
12:08
In terms of proliferation,
252
712000
2000
U smislu širenja,
12:10
nuclear energy has done more
253
714000
2000
nuklearna energija je učinila više
12:12
to dismantle nuclear weapons than any other activity.
254
716000
3000
na razmontiravanju nuklearnog oružja od bilo koje druge aktivnosti.
12:15
And that's why 10 percent of the electricity in this room,
255
719000
4000
I baš zato 10% struje u ovoj prostoriji,
12:19
20 percent of electricity
256
723000
2000
20% struje
12:21
in this room is probably nuclear.
257
725000
2000
u ovoj prostoriji vjerojatno dolazi od nuklearki.
12:23
Half of that is coming from dismantled warheads from Russia,
258
727000
4000
Polovina ovoga dolazi iz razmontiranih bojevih glava iz Rusije.
12:27
soon to be joined by our dismantled warheads.
259
731000
3000
Uskoro će biti pridružene našim bojevim glavama.
12:30
And so I would like to see the GNEP program,
260
734000
3000
I ja bih volio vidjeti GNEP program,
12:33
that was developed in the Bush administration, go forward aggressively.
261
737000
3000
koji je bio razvijen za vrijeme Bushove administracije, kako agresivno napreduje.
12:36
And I was glad to see that president Obama
262
740000
2000
I bio sam presretan kad sam vidio kako predsjednik Obama
12:38
supported the nuclear fuel bank strategy
263
742000
3000
podržava strategiju banke nuklearnog goriva
12:41
when he spoke in Prague the other week.
264
745000
2000
u svom govoru u Pragu prošloga tjedna.
12:43
One more subject. Genetically engineered food crops,
265
747000
3000
Još jedna stvar. Genetički modificirane prehrambene biljke,
12:46
in my view, as a biologist,
266
750000
2000
s mog gledišta, kao biologa,
12:48
have no reason to be controversial.
267
752000
2000
nemaju razloga biti kontroverzne.
12:50
My fellow environmentalists, on this subject,
268
754000
2000
Moji kolege ekolozi, po ovom pitanju,
12:52
have been irrational, anti-scientific, and very harmful.
269
756000
4000
bili su iracionalni, ne-znanstveni i vrlo štetni.
12:56
Despite their best efforts,
270
760000
2000
Uprkos njihovim najboljim naporima,
12:58
genetically engineered crops are the most
271
762000
2000
genetički modificirane biljke su najuspješnija
13:00
rapidly successful agricultural innovation in history.
272
764000
4000
agrikulturna inovacija u povijesti.
13:04
They're good for the environment because they enable no-till farming,
273
768000
3000
One su dobre za okoliš zato što omogućavaju poljodjelstvo bez kopanja,
13:07
which leaves the soil in place,
274
771000
2000
koje tlo ostavlja na mjestu,
13:09
getting healthier from year to year --
275
773000
2000
što ga čini zdravijim iz godine u godinu.
13:11
slso keeps less carbon dioxide going from the soil
276
775000
2000
Osim toga smanjuju količinu ugljičnog dioksida koji iz tla
13:13
into the atmosphere.
277
777000
2000
dospijeva u atmosferu.
13:15
They reduce pesticide use.
278
779000
2000
Smanjuju korištenje pesticida.
13:17
And they increase yield, which allows you to have your
279
781000
2000
I povećavaju urod, što vam omogućuje da smanjite
13:19
agricultural area be smaller,
280
783000
3000
poljodjelsku površinu.
13:22
and therefore more wild area is freed up.
281
786000
3000
I tako se oslobađa prostor za divljinu.
13:25
By the way, this map from 2006
282
789000
2000
Na primjer, ova karta iz 2006. godine
13:27
is out of date because it shows Africa
283
791000
2000
je zastarjela jer još uvijek prikazuje Afriku
13:29
still under the thumb of Greenpeace,
284
793000
2000
pod palcem Greenpeace-a
13:31
and Friends of the Earth from Europe,
285
795000
3000
i Prijatelja prirode iz Europe.
13:34
and they're finally getting out from under that.
286
798000
2000
I oni konačno izlaze iz toga.
13:36
And biotech is moving rapidly in Africa, at last.
287
800000
3000
A biotehnologija ubrzano ulazi u Afriku, konačno.
13:39
This is a moral issue.
288
803000
2000
To je moralno pitanje.
13:41
The Nuffield Council on Bioethics
289
805000
2000
Nuffieldski sabor bioetike
13:43
met on this issue twice in great detail
290
807000
2000
sastao se zbog tog problema dva puta i detaljno raspravljao
13:45
and said it is a moral imperative
291
809000
2000
te zaključio kako je moralni imperativ
13:47
to make genetically engineered crops readily available.
292
811000
3000
učiniti genetički modificirane usjeve ubrzano dostupnima.
13:50
Speaking of imperatives, geoengineering is taboo now,
293
814000
3000
Govoreći o imperativima, geoinženjering je sada tabu,
13:53
especially in government circles,
294
817000
2000
posebno u krugovima vlasti,
13:55
though I think there was a DARPA meeting on it a couple of weeks ago,
295
819000
2000
mada ja mislim da je bio DARPA sastanak prije par tjedana na tu temu.
13:57
but it will be on your plate --
296
821000
2000
Ali to će vam biti predstavljeno,
13:59
not this year but pretty soon,
297
823000
3000
ne ove godine, ali prilično skoro.
14:02
because some harsh realizations are coming along.
298
826000
3000
Zato što neke surove realizacije dolaze s tim.
14:05
This is a list of them.
299
829000
2000
Ovo je njihov popis.
14:07
Basically the news is going to keep getting more scary.
300
831000
3000
U osnovi vijesti nastavljaju biti sve više zastrašujuće.
14:10
There will be events,
301
834000
2000
Događat će se stvari,
14:12
like 35,000 people dying of a heat wave,
302
836000
3000
poput 35.000 mrtvih u toplotnom udaru,
14:15
which happened a while back.
303
839000
2000
kakav se nedavno dogodio.
14:17
Like cyclones coming up toward Bangladesh.
304
841000
3000
Kao cikloni koji idu prema Bangladešu.
14:20
Like wars over water,
305
844000
2000
Kao ratovi oko vode,
14:22
such as in the Indus.
306
846000
2000
kao oni oko rijeke Indus.
14:24
And as those events keep happening
307
848000
2000
I kako se te stvari događaju
14:26
we're going to say, "Okay, what can we do about that really?"
308
850000
2000
mi ćemo reći: "U redu, što se stvarno može s tim napraviti?"
14:28
But there's this little problem with geoengineering:
309
852000
5000
Ali postoji taj mali problem s geoinženjeringom.
14:33
what body is going to decide
310
857000
4000
Što će tijelo odlučiti?
14:37
who gets to engineer? How much they do? Where they do it?
311
861000
2000
Čiji će biti inženjeri? Koliko će napraviti? Gdje će to napraviti?
14:39
Because everybody is downstream,
312
863000
2000
Zato što su svi nizvodno,
14:41
downwind of whatever is done.
313
865000
3000
nizvodno od svega što je učinjeno.
14:44
And if we just taboo it completely
314
868000
2000
I ako to samo potpuno tabuiziramo
14:46
we could lose civilization.
315
870000
2000
mogli bismo izgubiti civilizaciju.
14:48
But if we just say "OK,
316
872000
3000
No, ako samo kažemo OK,
14:51
China, you're worried, you go ahead.
317
875000
2000
Kina, vi ste zabrinuti, vi vodite.
14:53
You geoengineer your way. We'll geoengineer our way."
318
877000
4000
Vi napravite geoinženjering na svoj način. Mi ćemo napraviti svoj geoinženjering.
14:57
That would be considered an act of war by both nations.
319
881000
3000
Ovo bi se smatralo objavom rata od strane obje nacije.
15:00
So this is very interesting diplomacy coming along.
320
884000
4000
I tako neka vrlo zanimljiva diplomacija dolazi s tim.
15:04
I should say, it is more practical than people think.
321
888000
3000
Ja bih rekao, ovo je praktičnije nego što ljudi misle.
15:07
Here is an example that climatologists like a lot,
322
891000
3000
Ovo je primjer koji se jako sviđa klimatolozima.
15:10
one of the dozens of geoengineering ideas.
323
894000
2000
Jedna od brojnih geoinžinjerskih ideja.
15:12
This one came from the sulfur dioxide
324
896000
2000
Ona dolazi od sumpornog dioksida
15:14
from Mount Pinatubo in 1991 --
325
898000
3000
iz Mount Pinatubo iz 1991. godine.
15:17
cooled the earth by half a degree.
326
901000
4000
Ohladila je Zemlju za pola stupnja.
15:21
There was so much ice in 1992, the following year,
327
905000
2000
Ovoliko je bilo leda 1992. godine, naredne godine,
15:23
that there was a bumper crop of polar bear cubs
328
907000
3000
došlo je do neočekivanog porasta broja mladunčadi polarnog medvjeda
15:26
who were known as the Pinatubo cubs.
329
910000
2000
koja su prozvana Pinatubo mladunčad.
15:28
To put sulfur dioxide in the stratosphere
330
912000
2000
Staviti sumporni dioksid u stratosferu
15:30
would cost on the order of a billion dollars a year.
331
914000
3000
koštalo bi otprilike milijardu dolara godišnje.
15:33
That's nothing, compared to all of the other
332
917000
3000
To je ništa u usporedbi sa svim ostalim stvarima
15:36
things we may be trying to do about energy.
333
920000
2000
koje pokušavamo učiniti oko energije.
15:38
Just to run by another one:
334
922000
3000
Samo da prođemo kroz drugu ideju,
15:41
this is a plan to brighten the reflectance of ocean clouds,
335
925000
3000
ovo je plan kako posvijetliti refleksiju oceanskih oblaka
15:44
by atomizing seawater;
336
928000
2000
atomiziranjem morske vode.
15:46
that would brighten the albedo of the whole planet.
337
930000
2000
Ovo bi posvijetlilo, povećalo koeficijent refleksije cijeloga planeta.
15:48
A nice one, because it can happen
338
932000
2000
Vrlo lijepo, jer bi se to moglo napraviti
15:50
lots of little ways in lots of little places,
339
934000
2000
na mnogo različitih načina, na mnogo malih mjesta,
15:52
is by copying the ancient Amazon Indians
340
936000
2000
kopiranjem amazonskih indijanaca
15:54
who made good agricultural soil
341
938000
2000
koji su proizvodili dobro poljoprivredno tlo
15:56
by pyrolizing, smoldering, plant waste,
342
940000
4000
pirolizom, paljenjem biljnog otpada.
16:00
and biochar fixes large quantities of carbon
343
944000
3000
I biougljen (ugljen nastao pirolizom biomase) fiksira velike količine ugljika
16:03
while it's improving the soil.
344
947000
2000
i pri tome poboljšava kvalitetu tla.
16:05
So here is where we are.
345
949000
3000
I evo gdje smo sada.
16:08
Nobel Prize-winning climatologist Paul Crutzen
346
952000
3000
Nobelovac, klimatolog Paul Crutzen
16:11
calls our geological era the Anthropocene,
347
955000
3000
zove našu geološku eru Antropocen –
16:14
the human-dominated era. We are stuck
348
958000
3000
era dominacije ljudi. Mi smo zaglavili
16:17
with its obligations.
349
961000
3000
s tom obavezom.
16:20
In the Whole Earth Catalog, my first words were,
350
964000
2000
U "Katalogu cijele Zemlje", moj su prve riječi bile:
16:22
"We are as Gods, and might as well get good at it."
351
966000
2000
"Mi smo poput bogova, i mogli bismo postati dobri u tome."
16:24
The first words of Whole Earth Discipline
352
968000
3000
Prve riječi u "Disciplini cijele Zemlje"
16:27
are, "We are as Gods, and have to get good at it."
353
971000
4000
su: "Mi smo poput bogova i moramo postati dobri u tome."
16:31
Thank you.
354
975000
2000
Hvala vam.
16:33

ABOUT THE SPEAKER
Stewart Brand - Environmentalist, futuristSince the counterculture '60s, Stewart Brand has been creating our internet-worked world. Now, with biotech accelerating four times faster than digital technology, Stewart Brand has a bold new plan ...
Why you should listen
With biotech accelerating four times faster than digital technology, the revival of extinct species is becoming possible. Stewart Brand plans to not only bring species back but restore them to the wild.
Brand is already a legend in the tech industry for things he’s created: the Whole Earth Catalog, The WELL, the Global Business Network, the Long Now Foundation, and the notion that “information wants to be free.” Now Brand, a lifelong environmentalist, wants to re-create -- or “de-extinct” -- a few animals that’ve disappeared from the planet.
Granted, resurrecting the woolly mammoth using ancient DNA may sound like mad science. But Brand’s Revive and Restore project has an entirely rational goal: to learn what causes extinctions so we can protect currently endangered species, preserve genetic and biological diversity, repair depleted ecosystems, and essentially “undo harm that humans have caused in the past.”
