U školi "Harbor" u Hong Kongu, Cezar Harada predaje budućim generacijama ekologa građansku nauku i izume. Preselio je učionicu u industrijski mega prostor gde maštovita deca rade s drvetom, metalom, hemijom, biologijom, optikom i, povremeno, s moćnim alatima, kako bi stvorili rešenja za pretnje s kojima se suočavaju svetski okeani. Tu im prenosi univerzalnu lekciju koju je naučio od njegovih roditelja kao dete: "Možeš da praviš nered, ali moraš da počistiš za sobom."

When I was a kid,
my parents would tell me,
my parents would tell me,
0

2816
Kada sam bio dete,
roditelji su mi govorili:
roditelji su mi govorili:
00:16
"You can make a mess,
but you have to clean up after yourself."
but you have to clean up after yourself."

3399
"Možeš da praviš nered,
ali moraš da počistiš za sobom."
ali moraš da počistiš za sobom."
00:20
So freedom came with responsibility.
2
8440
3336
Dakle, uz slobodu je išla odgovornost.
00:23
But my imagination would take me
to all these wonderful places,
to all these wonderful places,
3
11800
3576
Ali mašta me je vodila
na sva ta divna mesta,
na sva ta divna mesta,
00:27
where everything was possible.
4
15400
2096
gde je sve bilo moguće.
00:29
So I grew up in a bubble of innocence --
5
17520
2896
Pa sam odrastao
pod zlatnim zvonom nevinosti -
pod zlatnim zvonom nevinosti -
00:32
or a bubble of ignorance, I should say,
6
20440
2336
ili, rekao bih,
pod zlatnim zvonom neznanja
pod zlatnim zvonom neznanja
00:34
because adults would lie to us
to protect us from the ugly truth.
to protect us from the ugly truth.
7
22800
5096
jer su nas odrasli lagali kako bi
nas zaštitili od neprijatne istine.
nas zaštitili od neprijatne istine.
00:39
And growing up, I found out
that adults make a mess,
that adults make a mess,
8
27920
3576
A odrastajući sam otkrio
da odrasli prave nered
da odrasli prave nered
00:43
and they're not very good
at cleaning up after themselves.
at cleaning up after themselves.
9
31520
2800
i da nisu naročito dobri
u čišćenju za sobom.
u čišćenju za sobom.
00:47
Fast forward, I am an adult now,
10
35360
2136
Premotaćemo, i ja sam sad odrastao
00:49
and I teach citizen science and invention
at the Hong Kong Harbour School.
at the Hong Kong Harbour School.
11
37520
4976
i predajem građansku nauku i izume
u školi "Harbor" u Hong Kongu.
u školi "Harbor" u Hong Kongu.
00:54
And it doesn't take too long
12
42520
1336
I ne prođe mnogo vremena
00:55
before my students walk on a beach
and stumble upon piles of trash.
and stumble upon piles of trash.
13
43880
4216
pre nego što moji đaci, šetajući po plaži,
nalete na hrpe smeća.
nalete na hrpe smeća.
01:00
So as good citizens,
we clean up the beaches --
we clean up the beaches --
14
48120
2656
Pa, kao uzorni građani, čistimo plaže -
01:02
and no, he is not drinking alcohol,
and if he is, I did not give it to him.
and if he is, I did not give it to him.
15
50800
4720
i ne, on ne pije alkohol,
a ako pije, ja mu to nisam dao.
a ako pije, ja mu to nisam dao.
01:07
(Laughter)
16
55880
1760
(Smeh)
01:09
And so it's sad to say,
17
57960
1216
I tužno je to reći,
01:11
but today more than 80 percent
of the oceans have plastic in them.
of the oceans have plastic in them.
18
59200
3776
ali danas više od 80 procenata
okeana sadrži plastiku.
okeana sadrži plastiku.
01:15
It's a horrifying fact.
19
63000
1280
To je jeziva činjenica.
01:16
And in past decades,
20
64800
1376
A proteklih decenija,
01:18
we've been taking those big ships out
and those big nets,
and those big nets,
21
66200
3456
isplovljavali smo velikim brodovima
i tim velikim mrežama
i tim velikim mrežama
01:21
and we collect those plastic bits
that we look at under a microscope,
that we look at under a microscope,
22
69680
3336
smo sakupljali te plastične deliće
koje smo posmatrali pod mikroskopom
koje smo posmatrali pod mikroskopom
01:25
and we sort them,
23
73040
1216
i sortirali,
01:26
and then we put this data onto a map.
24
74280
1762
a onda smo podatke upisivali na kartu.
01:28
But that takes forever,
it's very expensive,
it's very expensive,
25
76440
2336
Ali to traje večnost, veoma je skupo
01:30
and so it's quite risky
to take those big boats out.
to take those big boats out.
26
78800
3136
i prilično je rizično
isplovljavati tim velikim brodovima.
isplovljavati tim velikim brodovima.
01:33
So with my students, ages six to 15,
27
81960
2936
Pa sam sa svojim đacima,
uzrasta od šest do 15 godina,
uzrasta od šest do 15 godina,
01:36
we've been dreaming
of inventing a better way.
of inventing a better way.
28
84920
2216
sanjao o nalaženju boljeg načina.
01:39
So we've transformed our tiny
Hong Kong classroom into a workshop.
Hong Kong classroom into a workshop.
29
87160
4416
Zato smo pretvorili našu malenu
učionicu u Hong Kongu u radionicu.
učionicu u Hong Kongu u radionicu.
01:43
And so we started building
this small workbench,
this small workbench,
30
91600
2656
I počeli smo da pravimo
ovu malu radnu tezgu,
ovu malu radnu tezgu,
01:46
with different heights,
so even really short kids can participate.
so even really short kids can participate.
31
94280
3176
sa raznim nivoima, da čak
i veoma niska deca mogu da učestvuju.
i veoma niska deca mogu da učestvuju.
01:49
And let me tell you, kids with power tools
are awesome and safe.
are awesome and safe.
32
97480
4176
I dozvolite da vam kažem, deca sa
električnim alatima su strava i bezbedna.
električnim alatima su strava i bezbedna.
01:53
(Laughter)
33
101680
1336
(Smeh)
01:55
Not really.
34
103040
1896
Baš i nisu.
01:56
And so, back to plastic.
35
104960
1216
Vratimo se plastici.
01:58
We collect this plastic and we grind it
to the size we find it in the ocean,
to the size we find it in the ocean,
36
106200
3616
Sakupljamo plastiku i meljemo je
do razmera koje nalazimo u okeanu,
do razmera koje nalazimo u okeanu,
02:01
which is very small
because it breaks down.
because it breaks down.
37
109840
2176
a to je veoma sitno zbog razlaganja.
02:04
And so this is how we work.
38
112040
1376
Dakle, evo kako radimo.
02:05
I let the imaginations
of my students run wild.
of my students run wild.
39
113440
3136
Puštam da mašta mojih đaka podivlja.
02:08
And my job is to try to collect
the best of each kid's idea
the best of each kid's idea
40
116600
4256
A moj je posao da pokušam da sakupim
najbolje iz svake dečje ideje
najbolje iz svake dečje ideje
02:12
and try to combine it into something
that hopefully would work.
that hopefully would work.
41
120880
4280
i da pokušam to da uklopim u nešto
što će, nadam se, da funkcioniše.
što će, nadam se, da funkcioniše.
02:17
And so we have agreed
that instead of collecting plastic bits,
that instead of collecting plastic bits,
42
125920
3136
Pa smo se složili da ćemo
umesto sakupljanja plastičnih komadića,
umesto sakupljanja plastičnih komadića,
02:21
we are going to collect only the data.
43
129080
1976
samo sakupljati podatke.
02:23
So we're going to get an image
of the plastic with a robot --
of the plastic with a robot --
44
131080
2976
Robot će nam napraviti slike plastike -
02:26
so robots, kids get very excited.
45
134080
2376
zbog robota su deca veoma uzbuđena.
02:28
And the next thing we do --
we do what we call "rapid prototyping."
we do what we call "rapid prototyping."
46
136480
3143
A sledeće što radimo -
nazivamo to "brzim prototipom".
nazivamo to "brzim prototipom".
02:31
We are so rapid at prototyping
47
139647
1689
Toliko brzo pravimo prototipe
02:33
that the lunch is still in the lunchbox
when we're hacking it.
when we're hacking it.
48
141360
3176
da je ručak još uvek u kutiji
dok ga sastavljamo.
dok ga sastavljamo.
02:36
(Laughter)
49
144560
1296
(Smeh)
02:37
And we hack table lamps and webcams,
into plumbing fixtures
into plumbing fixtures
50
145880
4256
A mi prekucavamo stone lampe, vebkamere
u vodovodno instalacijska učvršćenja
u vodovodno instalacijska učvršćenja
02:42
and we assemble that into a floating robot
that will be slowly moving through water
that will be slowly moving through water
51
150160
5136
i to sklapamo u plutajućeg robota
koji će se sporo kretati po vodi
koji će se sporo kretati po vodi
02:47
and through the plastic
that we have there --
that we have there --
52
155320
2096
i po plastici koja se tamo nalazi -
02:49
and this is the image
that we get in the robot.
that we get in the robot.
53
157440
2191
a ovo je slika koju je napravio robot.
02:51
So we see the plastic pieces
floating slowly through the sensor,
floating slowly through the sensor,
54
159655
3721
Vidimo plastične delove
kako sporo plutaju kroz senzor,
kako sporo plutaju kroz senzor,
02:55
and the computer on board
will process this image,
will process this image,
55
163400
3296
a kompjuter na brodu
će da obradi ovu sliku
će da obradi ovu sliku
02:58
and measure the size of each particle,
56
166720
2096
i da izmeri veličinu svake čestice,
03:00
so we have a rough estimate
of how much plastic there is in the water.
of how much plastic there is in the water.
57
168840
4120
pa ćemo imati grubu procenu
o količini plastike u vodi.
o količini plastike u vodi.
03:05
So we documented
this invention step by step
this invention step by step
58
173520
3016
Pa smo svaki korak
izrade ovog izuma dokumentovali
izrade ovog izuma dokumentovali
03:08
on a website for inventors
called Instructables,
called Instructables,
59
176560
3376
na vebsajtu za pronalazače,
koji se zove Instructables,
koji se zove Instructables,
03:11
in the hope that somebody
would make it even better.
would make it even better.
60
179960
2800
u nadi da će ga neko čak i unaprediti.
03:15
What was really cool about this project
was that the students saw a local problem,
was that the students saw a local problem,
61
183838
3858
Sjajna stvar kod ovog projekta je to
što su đaci prepoznali lokalni problem
što su đaci prepoznali lokalni problem
03:19
and boom -- they are trying
to immediately address it.
to immediately address it.
62
187720
2667
i, hop! - odmah su pokušali da ga reše.
03:22
[I can investigate my local problem]
63
190411
2325
[Mogu da istražim lokalni problem]
03:24
But my students in Hong Kong
are hyperconnected kids.
are hyperconnected kids.
64
192760
3216
Ali moji đaci u Hong Kongu
su izuzetno umrežena deca.
su izuzetno umrežena deca.
03:28
And they watch the news,
they watch the Internet,
they watch the Internet,
65
196000
2296
Posmatraju vesti, prate internet sadržaje
03:30
and they came across this image.
66
198320
2240
i naleteli su na ovaj prizor.
03:33
This was a child, probably under 10,
cleaning up an oil spill bare-handed,
cleaning up an oil spill bare-handed,
67
201840
4736
Ovo dete, verovatno mlađe od 10 god,
čisti naftnu mrlju, golih ruku,
čisti naftnu mrlju, golih ruku,
03:38
in the Sundarbans, which is the world's
largest mangrove forest in Bangladesh.
largest mangrove forest in Bangladesh.
68
206600
4496
u Sundarbansu, u Bangladešu u kome se
nalazi najveća šuma mangrovine na svetu.
nalazi najveća šuma mangrovine na svetu.
03:43
So they were very shocked,
69
211120
2456
Pa su bili izuzetno potreseni,
03:45
because this is the water they drink,
this is the water they bathe in,
this is the water they bathe in,
70
213600
3296
jer je ovo voda koju piju,
voda u kojoj se kupaju,
voda u kojoj se kupaju,
03:48
this is the water they fish in --
this is the place where they live.
this is the place where they live.
71
216920
3376
ovo je voda u kojoj pecaju -
ovo je mesto na kome žive.
ovo je mesto na kome žive.
03:52
And also you can see the water is brown,
the mud is brown and oil is brown,
the mud is brown and oil is brown,
72
220320
3896
Takođe, možete da vidite da je voda smeđa,
mulj je smeđ i nafta je smeđa,
mulj je smeđ i nafta je smeđa,
03:56
so when everything is mixed up,
73
224240
1477
kada je sve izmešano,
03:57
it's really hard to see
what's in the water.
what's in the water.
74
225741
2475
veoma je teško videti šta je u vodi.
04:00
But, there's a technology
that's rather simple,
that's rather simple,
75
228240
2256
Ali, postoji
veoma jednostavna tehnologija,
veoma jednostavna tehnologija,
04:02
that's called spectrometry,
76
230520
1536
koja se zove spektometrija
04:04
that allows you see what's in the water.
77
232080
1905
i omogućuje vam da vidite šta je u vodi.
04:06
So we built a rough prototype
of a spectrometer,
of a spectrometer,
78
234009
3047
Pa smo napravili
grubi prototip spektometra,
grubi prototip spektometra,
04:09
and you can shine light
through different substances
through different substances
79
237080
2936
možete da obasjavate različite supstance
04:12
that produce different spectrums,
80
240040
2416
i tako proizvodite različite spektre,
04:14
so that can help you
identify what's in the water.
identify what's in the water.
81
242480
3856
i to vam može pomoći
da otkrijete šta je u vodi.
da otkrijete šta je u vodi.
04:18
So we packed this prototype of a sensor,
82
246360
2896
Pa smo spakovali ovaj prototip senzora
04:21
and we shipped it to Bangladesh.
83
249280
2240
i poslali smo ga u Bangladeš.
04:23
So what was cool about this project
84
251989
1667
Kod ovog projekta je sjajno
04:25
was that beyond addressing
a local problem,
a local problem,
85
253680
3135
to što su mimo
bavljenja lokalnim problemom
bavljenja lokalnim problemom
ili posmatranja lokalnog problema,
04:28
or looking at a local problem,
86
256839
1430
04:30
my students used their empathy
and their sense of being creative
and their sense of being creative
87
258293
3923
moji đaci, vođeni svojom empatijom
i osećajem kreativnosti,
i osećajem kreativnosti,
04:34
to help, remotely, other kids.
88
262240
2256
pomogli drugoj udaljenoj deci.
[Mogu da istražujem udaljeni problem]
04:36
[I can investigate a remote problem]
89
264520
1715
04:38
So I was very compelled
by doing the second experiments,
by doing the second experiments,
90
266259
2620
Pa sam bio primoran
da izvodim nove eksperimente
da izvodim nove eksperimente
04:40
and I wanted to take it even further --
91
268903
2513
i želeo sam da odem još dalje -
04:43
maybe addressing an even harder problem,
and it's also closer to my heart.
and it's also closer to my heart.
92
271440
4600
da se bavimo čak i težim problemom,
koji je pritom meni blizak.
koji je pritom meni blizak.
04:48
So I'm half Japanese and half French,
93
276560
2616
Ja sam polu-Japanac i polu-Francuz
04:51
and maybe you remember in 2011
there was a massive earthquake in Japan.
there was a massive earthquake in Japan.
94
279200
5320
i možda se sećate da se 2011.
desio razoran zemljotres u Japanu.
desio razoran zemljotres u Japanu.
04:57
It was so violent that it triggered
several giant waves --
several giant waves --
95
285120
3816
Toliko je bio žestok da je pokrenuo
nekoliko ogromnih talasa -
nekoliko ogromnih talasa -
05:00
they are called tsunami --
96
288960
1416
koji se nazivaju cunamijima -
05:02
and those tsunami destroyed many cities
on the eastern coast of Japan.
on the eastern coast of Japan.
97
290400
6960
a ti cunamiji su uništili mnoge gradove
na istočnoj obali Japana.
na istočnoj obali Japana.
05:10
More than 14,000 people
died in an instant.
died in an instant.
98
298680
3360
Preko 14 000 ljudi je stradalo u momentu.
05:15
Also, it damaged the nuclear
power plant of Fukushima,
power plant of Fukushima,
99
303600
3736
Takođe je oštetilo
nuklearnu elektranu u Fukušimi,
nuklearnu elektranu u Fukušimi,
05:19
the nuclear power plant just by the water.
100
307360
2680
nuklearnu elektranu tik pored vode.
05:22
And today, I read the reports
101
310480
2416
I danas čitam izveštaje
05:24
and an average of 300 tons
102
312920
3056
da prosečno 300 tona
05:28
are leaking from the nuclear power plant
into the Pacific Ocean.
into the Pacific Ocean.
103
316000
3576
curi iz nuklearne elektrane u Tihi okean.
05:31
And today the whole Pacific Ocean
has traces of contamination of cesium-137.
has traces of contamination of cesium-137.
104
319600
6376
A danas u čitavom Tihom okeanu
imamo tragove zagađenosti cezijumom-137.
imamo tragove zagađenosti cezijumom-137.
05:38
If you go outside on the West Coast,
you can measure Fukushima everywhere.
you can measure Fukushima everywhere.
105
326000
4416
Ako izađete na Zapadnu obalu,
možete svuda da izmerite Fukušimu.
možete svuda da izmerite Fukušimu.
05:42
But if you look at the map,
it can look like most of the radioactivity
it can look like most of the radioactivity
106
330440
3296
No, ako posmatrate kartu, može se činiti
da je radioaktivnost uglavnom
da je radioaktivnost uglavnom
05:45
has been washed away
from the Japanese coast,
from the Japanese coast,
107
333760
2096
sprana sa japanske obale
05:47
and most of it is now --
it looks like it's safe, it's blue.
it looks like it's safe, it's blue.
108
335880
2816
i uglavnom i jeste -
izgleda bezbedno, plavo.
izgleda bezbedno, plavo.
05:50
Well, reality is a bit
more complicated than this.
more complicated than this.
109
338720
3416
Pa, stvarnost je
malčice složenija od toga.
malčice složenija od toga.
05:54
So I've been going to Fukushima
every year since the accident,
every year since the accident,
110
342160
3656
Ja posećujem Fukušimu
svake godine od nesreće
svake godine od nesreće
05:57
and I measure independently
and with other scientists,
and with other scientists,
111
345840
2536
i merim nezavisno i sa drugim naučnicima,
06:00
on land, in the river --
112
348400
1856
na kopnu, u rekama -
06:02
and this time we wanted to take the kids.
113
350280
2736
a ovaj put smo želeli da povedemo decu.
06:05
So of course we didn't take the kids,
the parents wouldn't allow that to happen.
the parents wouldn't allow that to happen.
114
353040
3776
Naravno da nismo poveli decu,
roditelji to ne bi dozvolili.
roditelji to ne bi dozvolili.
06:08
(Laughter)
115
356840
1336
(Smeh)
06:10
But every night we would report
to "Mission Control" --
to "Mission Control" --
116
358200
3936
Ali svako veče smo slali izveštaj
"Kontrolnoj misiji" -
"Kontrolnoj misiji" -
06:14
different masks they're wearing.
117
362160
2176
nose različite maske.
06:16
It could look like they didn't take
the work seriously, but they really did
the work seriously, but they really did
118
364360
4376
Može vam se činiti da nisu
ozbiljno shvatili posao, ali zaista jesu
ozbiljno shvatili posao, ali zaista jesu
06:20
because they're going to have to live
with radioactivity their whole life.
with radioactivity their whole life.
119
368760
4200
jer će morati da žive s radioaktivnošću
čitav svoj život.
čitav svoj život.
06:25
And so what we did with them
120
373640
2056
A sa njima
06:27
is that we'd discuss the data
we collected that day,
we collected that day,
121
375720
2616
smo raspravljali podatke
koje smo tog dana sakupili
koje smo tog dana sakupili
06:30
and talk about where
we should be going next --
we should be going next --
122
378360
2191
i razgovarali smo o sledećim koracima -
06:32
strategy, itinerary, etc...
123
380575
2121
strategijama, maršrutama itd...
06:34
And to do this, we built
a very rough topographical map
a very rough topographical map
124
382720
3616
A kako bismo to uradili,
napravili smo grubu topografsku kartu
napravili smo grubu topografsku kartu
06:38
of the region around
the nuclear power plant.
the nuclear power plant.
125
386360
2856
područja oko nuklearne elektrane.
06:41
And so we built the elevation map,
126
389240
2016
Pa smo napravili kartu nadmorske visine,
06:43
we sprinkled pigments to represent
real-time data for radioactivity,
real-time data for radioactivity,
127
391280
4616
naprskali je pigmentima koji predstavljaju
realne podatke o radioaktivnosti
realne podatke o radioaktivnosti
06:47
and we sprayed water
to simulate the rainfall.
to simulate the rainfall.
128
395920
4336
i poprskali smo je vodom
da bi simulirali kišu.
da bi simulirali kišu.
06:52
And with this we could see
that the radioactive dust
that the radioactive dust
129
400280
2976
Tako smo mogli da vidimo
kako se radioaktivna prašina
kako se radioaktivna prašina
06:55
was washing from the top of the mountain
into the river system,
into the river system,
130
403280
3056
spira s vrha planine u rečni sistem
06:58
and leaking into the ocean.
131
406360
1536
i curi u okean.
06:59
So it was a rough estimate.
132
407920
1600
Dakle, to je bila gruba procena.
07:02
But with this in mind,
we organized this expedition,
we organized this expedition,
133
410680
2936
Ali imajući ovo na umu,
organizovali smo ekspediciju,
organizovali smo ekspediciju,
07:05
which was the closest civilians have been
to the nuclear power plant.
to the nuclear power plant.
134
413640
3616
koja se primakla nuklearnoj elektrani
najbliže što je ijedan civil ikad bio.
najbliže što je ijedan civil ikad bio.
07:09
We are sailing 1.5 kilometers away
from the nuclear power plant,
from the nuclear power plant,
135
417280
4336
Plovimo 1,5 km daleko
od nuklearne elektrane
od nuklearne elektrane
07:13
and with the help of the local fisherman,
136
421640
1953
i uz pomoć lokalnih ribolovaca,
07:15
we are collecting sediment from the seabed
137
423617
2239
sakupljamo talog sa morskog dna
07:17
with a custom sediment sampler
we've invented and built.
we've invented and built.
138
425880
3456
prilagođenim priborom za uzorke
koji smo izumili i sagradili.
koji smo izumili i sagradili.
07:21
We pack the sediment into small bags,
139
429360
3256
Popakovali smo talog u male kese,
07:24
we then dispatch them
to hundreds of small bags
to hundreds of small bags
140
432640
2256
potom smo ih otpremili u stotine kesica
07:26
that we send to different universities,
141
434920
1936
koje smo poslali različitim fakultetima
07:28
and we produce the map
of the seabed radioactivity,
of the seabed radioactivity,
142
436880
2976
i tako smo napravili mapu
radioaktivnosti morskog dna,
radioaktivnosti morskog dna,
07:31
especially in estuaries
where the fish will reproduce,
where the fish will reproduce,
143
439880
2536
naročito u estuarima
gde se ribe razmnožavaju
gde se ribe razmnožavaju
07:34
and I will hope that we will have improved
144
442440
2056
i nadam se da smo unapredili
07:36
the safety of the local fishermen
and of your favorite sushi.
and of your favorite sushi.
145
444520
3096
bezbednost lokalnih ribolovaca
i vašeg omiljenog sušija.
i vašeg omiljenog sušija.
07:39
(Laughter)
146
447640
1296
(Smeh)
07:40
You can see a progression here --
147
448960
1576
Ovde vidite napredak -
07:42
we've gone from a local problem
to a remote problem to a global problem.
to a remote problem to a global problem.
148
450560
4536
krenuli smo od lokalnog problema,
preko udaljenog problema do globalnog.
preko udaljenog problema do globalnog.
07:47
And it's been super exciting
to work at these different scales,
to work at these different scales,
149
455120
2953
I bilo je veoma uzbudljivo
raditi na ovim različitim razmerama,
raditi na ovim različitim razmerama,
07:50
with also very simple,
open-source technologies.
open-source technologies.
150
458097
3559
takođe, uz pomoć jednostavne tehnologije
dostupne svima.
dostupne svima.
07:53
But at the same time,
it's been increasingly frustrating
it's been increasingly frustrating
151
461680
3336
Ali istovremeno nas je
sve više uznemiravalo
sve više uznemiravalo
07:57
because we have only started to measure
the damage that we have done.
the damage that we have done.
152
465040
3696
to što smo tek počeli da merimo
štetu koju smo uzrokovali.
štetu koju smo uzrokovali.
08:00
We haven't even started
to try to solve the problems.
to try to solve the problems.
153
468760
4080
Nismo još ni počeli
da pokušavamo da rešimo probleme.
da pokušavamo da rešimo probleme.
08:05
And so I wonder
if we should just take a leap
if we should just take a leap
154
473640
2776
Pa se pitam da li bismo
prosto trebali da se hitnemo
prosto trebali da se hitnemo
08:08
and try to invent better ways
to do all these things.
to do all these things.
155
476440
4640
i pokušamo da pronađemo bolje načine
da radimo sve ovo.
da radimo sve ovo.
08:13
And so the classroom
started to feel a little bit small,
started to feel a little bit small,
156
481520
3576
Stoga nam je učionica
postajala sve tešnja,
postajala sve tešnja,
08:17
so we found an industrial
site in Hong Kong,
site in Hong Kong,
157
485120
2696
pa smo pronašli
industrijsko gradilište u Hong Kongu
industrijsko gradilište u Hong Kongu
08:19
and we turned it into
the largest mega-space
the largest mega-space
158
487840
3256
i pretvorili smo ga u najveći mega prostor
08:23
focused on social
and environmental impact.
and environmental impact.
159
491120
3176
usredsređen na društveni
i ekološki uticaj.
i ekološki uticaj.
08:26
It's in central Hong Kong,
160
494320
1296
U centru je Hong Konga
08:27
and it's a place we can work
with wood, metal, chemistry,
with wood, metal, chemistry,
161
495640
3216
i to je mesto na kom možemo
da radimo s drvetom, metalom, hemijom,
da radimo s drvetom, metalom, hemijom,
08:30
a bit of biology, a bit of optics,
162
498880
1626
nešto biologije, nešto optike,
08:32
basically you can build
pretty much everything there.
pretty much everything there.
163
500530
2492
u suštini, ovde
možete da napravite skoro sve.
možete da napravite skoro sve.
08:35
And its a place where
adults and kids can play together.
adults and kids can play together.
164
503047
2969
I to je mesto na kom se odrasli
i deca mogu zajedno da igraju.
i deca mogu zajedno da igraju.
08:38
It's a place where
kids' dreams can come true,
kids' dreams can come true,
165
506040
3576
To je mesto na kom se
dečji snovi ostvaruju,
dečji snovi ostvaruju,
08:41
with the help of adults,
166
509640
1336
uz pomoć odraslih
08:43
and where adults can be kids again.
167
511000
1816
i gde odrasli mogu opet da budu deca.
08:44
Student: Acceleration! Acceleration!
168
512840
3136
Đak: Ubrzanje! Ubrzanje!
08:48
Cesar Harada: We're asking
questions such as,
questions such as,
169
516000
2135
Cezar Harada: Postavljamo pitanja, poput:
možemo li da izumimo prevoz budućnosti
na obnovljivu energiju?
na obnovljivu energiju?
08:50
can we invent the future of mobility
with renewable energy?
with renewable energy?
170
518159
2817
08:53
For example.
171
521000
1200
Na primer.
08:55
Or, can we help the mobility
of the aging population
of the aging population
172
523320
4296
Ili: možemo li da pospešimo
kretanje starijih ljudi,
kretanje starijih ljudi,
08:59
by transforming very standard wheelchairs
into cool, electric vehicles?
into cool, electric vehicles?
173
527640
4400
pretvarajući standardna kolica
u strava, električna vozila?
u strava, električna vozila?
09:05
So plastic, oil and radioactivity
are horrible, horrible legacies,
are horrible, horrible legacies,
174
533240
6536
Dakle, plastika, nafta i radioaktivnost
su grozna, grozna zaveštanja,
su grozna, grozna zaveštanja,
09:11
but the very worst legacy
that we can leave our children is lies.
that we can leave our children is lies.
175
539800
4520
ali najgore zaveštanje koje možemo
da ostavimo našoj deci su laži.
da ostavimo našoj deci su laži.
09:16
We can no longer afford
to shield the kids from the ugly truth
to shield the kids from the ugly truth
176
544760
5216
Ne možemo više priuštiti sebi
da štitimo decu od neprijatne istine
da štitimo decu od neprijatne istine
09:22
because we need their imagination
to invent the solutions.
to invent the solutions.
177
550000
3920
jer nam je potrebna njihova mašta
da izumimo rešenja.
da izumimo rešenja.
09:26
So citizen scientists, makers, dreamers --
178
554720
4976
Zato, građani naučnici, tvorci, sanjari,
09:31
we must prepare the next generation
179
559720
2696
moramo pripremiti nove generacije
09:34
that cares about
the environment and people,
the environment and people,
180
562440
3056
koje brinu za okolinu i za ljude
09:37
and that can actually
do something about it.
do something about it.
181
565520
2200
i koje zapravo mogu
da nešto urade povodom toga.
da nešto urade povodom toga.
09:40
Thank you.
182
568200
1216
Hvala vam.

ABOUT THE SPEAKER
Cesar Harada - Inventor, environmentalist, educatorTED Senior Fellow Cesar Harada aims to harness the forces of nature as he invents innovative remedies for man-made problems like oil spills and radioactive leaks.
Why you should listen
Cesar Harada believes that ocean currents, the wind and other naturally occuring phenomenon can provide unique inspiration and novel solutions to mankind’s worst disasters, like oil spills and radioactive leaks. A French-Japanese inventor and TED senior fellow, he is the creator of Protei, a revolutionary sailing technology -- featuring a front rudder, flexible hull and open-soure hardware -- that allows for efficient clean up of both oil and plastics from the sea. Currently based in London, Harada recently traveled to Japan and is designing Protei to measure radioactivity along the country's coast.
The general coordinator of the future International Ocean Station, Harada teaches at Goldsmiths University London. A former project leader at MIT, he graduated form the Royal College of Arts Design Interactions in London and worked at the Southampton University Hydrodynamics laboratory on wave energy. Harada has also studied animantion, and his films and installations have been seen at festivals and events across the world, from the United States to Japan.
