Cesar Harada õpetab Hong Kongi Harbour Schoolis igamehe-teadust ja leiutamist uuele põlvkonnale keskkonnaaktivistidele. Oma klassiruumi on ta sisse seadnud suurde tööstushoonesse, kus elava kujutlusvõimega lapsed saavad tegutseda puidu, metalli, kemikaalide, aga ka elektriliste tööriistadega, et välja mõelda ja katsetada lahendusi maailma ookeane ähvardavatele ohtudega toimetulekuks. Sellise lähenemisega kinnistab ta oma vanematelt lapsepõlves kuuldud õpetust :"Toa võib küll segi ajada, aga pärast tuleb enda järelt ära koristada."

When I was a kid,
my parents would tell me,
my parents would tell me,
0
1800
2816
Kui ma olin väike,
ütlesid vanemad mulle:
ütlesid vanemad mulle:
00:16
"You can make a mess,
but you have to clean up after yourself."
but you have to clean up after yourself."

3399
"Võid oma toa segi ajada, aga pärast
pead enda järelt ära koristama."
pead enda järelt ära koristama."
00:20
So freedom came with responsibility.
2
8440
3336
Vabadus käis koos vastutusega.
00:23
But my imagination would take me
to all these wonderful places,
to all these wonderful places,
3
11800
3576
Kuid mu fantaasia viis mind
igasugu imelistesse kohtadesse,
igasugu imelistesse kohtadesse,
00:27
where everything was possible.
4
15400
2096
kus kõik oli võimalik.
00:29
So I grew up in a bubble of innocence --
5
17520
2896
Niisiis kasvasin ma üles süütus mullis
00:32
or a bubble of ignorance, I should say,
6
20440
2336
või teadmatuse mullis, õigemini,
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
sest täiskasvanud valetasid meile,
et kaitsta meid inetu tõe eest.
et kaitsta meid inetu tõe eest.
00:39
And growing up, I found out
that adults make a mess,
that adults make a mess,
8
27920
3576
Kui sain suureks, avastasin,
et täiskasvanud tekitavad ka segadust,
et täiskasvanud tekitavad ka segadust,
00:43
and they're not very good
at cleaning up after themselves.
at cleaning up after themselves.
9
31520
2800
aga enda järelt koristamine
pole nende tugevaim külg.
pole nende tugevaim külg.
Ajas edasi hüpates
olen saanud täiskasvanuks
olen saanud täiskasvanuks
00:47
Fast forward, I am an adult now,
10
35360
2136
00:49
and I teach citizen science and invention
at the Hong Kong Harbour School.
at the Hong Kong Harbour School.
11
37520
4976
ja õpetan vastutustundlikku teadust ja
leiutamist Hong Kong Harbour Schoolis.
leiutamist Hong Kong Harbour Schoolis.
Rannas jalutades komistavad
lapsed üsna kiiresti,
lapsed üsna kiiresti,
00:54
And it doesn't take too long
12
42520
1336
00:55
before my students walk on a beach
and stumble upon piles of trash.
and stumble upon piles of trash.
13
43880
4216
prügihunnikute otsa.
01:00
So as good citizens,
we clean up the beaches --
we clean up the beaches --
14
48120
2656
Korralike kodanikena
koristame prügi rannast ära -
koristame prügi rannast ära -
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
ja ei, ta ei joo alkoholi või kui joob,
siis mina seda talle ei andnud.
siis mina seda talle ei andnud.
01:07
(Laughter)
16
55880
1760
Ja on kurb tõdeda,
01:09
And so it's sad to say,
17
57960
1216
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
et tänaseks on rohkem, kui 80%
ookeanidest plastikuga reostatud.
ookeanidest plastikuga reostatud.
See on õõvastav tõsiasi.
01:15
It's a horrifying fact.
19
63000
1280
01:16
And in past decades,
20
64800
1376
Me oleme aastakümneid
01:18
we've been taking those big ships out
and those big nets,
and those big nets,
21
66200
3456
käinud suurte laevade
ja suurte võrkudega merel
ja suurte võrkudega merel
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
ja kogunud neid plastjäätmeid,
mida uurime mikroskoobiga,
mida uurime mikroskoobiga,
01:25
and we sort them,
23
73040
1216
määrame nende koostise
01:26
and then we put this data onto a map.
24
74280
1762
ja kanname saadud andmed kaardile.
01:28
But that takes forever,
it's very expensive,
it's very expensive,
25
76440
2336
Aga see võtab tohutult aega
ja on väga kallis
ja on väga kallis
01:30
and so it's quite risky
to take those big boats out.
to take those big boats out.
26
78800
3136
ja suurte laevadega merel
käimine on küllalt riskantne.
käimine on küllalt riskantne.
Nii olen ma oma õpilastega,
kes on vanuses 6 kuni 15
kes on vanuses 6 kuni 15
01:33
So with my students, ages six to 15,
27
81960
2936
01:36
we've been dreaming
of inventing a better way.
of inventing a better way.
28
84920
2216
tahtnud leida mõnda paremat moodust.
01:39
So we've transformed our tiny
Hong Kong classroom into a workshop.
Hong Kong classroom into a workshop.
29
87160
4416
Oleme oma pisikesest Hong Kongi
klassiruumist teinud töökoja.
klassiruumist teinud töökoja.
Esmalt alustasime väikeste
tööpinkide ehitamisest,
tööpinkide ehitamisest,
01:43
And so we started building
this small workbench,
this small workbench,
30
91600
2656
01:46
with different heights,
so even really short kids can participate.
so even really short kids can participate.
31
94280
3176
tegime need eri kõrgustega, et ka
väiksemad lapsed saaksid osaleda.
väiksemad lapsed saaksid osaleda.
01:49
And let me tell you, kids with power tools
are awesome and safe.
are awesome and safe.
32
97480
4176
Ma ütlen - lapsed ja elektrilised
tööriistad on võimsad ja ohutud.
tööriistad on võimsad ja ohutud.
01:53
(Laughter)
33
101680
1336
Tegelikult mitte.
01:55
Not really.
34
103040
1896
01:56
And so, back to plastic.
35
104960
1216
Tagasi plastmassi juurde.
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
Me kogume plastmassi ja jahvatame
selle nii peeneks nagu ookeanis,
selle nii peeneks nagu ookeanis,
02:01
which is very small
because it breaks down.
because it breaks down.
37
109840
2176
See on väga peen puru,
sest see laguneb.
sest see laguneb.
02:04
And so this is how we work.
38
112040
1376
Ja me töötame nii:
02:05
I let the imaginations
of my students run wild.
of my students run wild.
39
113440
3136
Ma lasen oma õpilaste
kujutlusvõimel vabalt lennata.
kujutlusvõimel vabalt lennata.
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
Ja minu ülesanne on koguda
laste parimad ideed
laste parimad ideed
02:12
and try to combine it into something
that hopefully would work.
that hopefully would work.
41
120880
4280
ja püüda kombineerida sellest midagi,
mis loodetavasti töötab.
mis loodetavasti töötab.
02:17
And so we have agreed
that instead of collecting plastic bits,
that instead of collecting plastic bits,
42
125920
3136
Me leppisime kokku, et
plastmassi kogumise asemel
plastmassi kogumise asemel
02:21
we are going to collect only the data.
43
129080
1976
kogume me ainult andmeid.
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
Nii me saame roboti abil
pildi sellest plastmassist.
pildi sellest plastmassist.
02:26
so robots, kids get very excited.
45
134080
2376
Robotid on laste jaoks väga põnevad.
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
Järgmiseks teeme seda, mida
nimetame "kiireks prototüüpimiseks".
nimetame "kiireks prototüüpimiseks".
02:31
We are so rapid at prototyping
47
139647
1689
Suudame prototüüpe teha nii kiirelt,
02:33
that the lunch is still in the lunchbox
when we're hacking it.
when we're hacking it.
48
141360
3176
et lõunasöök on alles karbis,
kui me seda juba häkime.
kui me seda juba häkime.
(Naer)
02:36
(Laughter)
49
144560
1296
Me häkime laualampe ja
veebikaameraid torujuppidesse
veebikaameraid torujuppidesse
02:37
And we hack table lamps and webcams,
into plumbing fixtures
into plumbing fixtures
50
145880
4256
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
ja ühendame need ujuk-robotiga,
mis hakkab aeglaselt vees liikuma
mis hakkab aeglaselt vees liikuma
02:47
and through the plastic
that we have there --
that we have there --
52
155320
2096
läbi plastiku, mis seal on
02:49
and this is the image
that we get in the robot.
that we get in the robot.
53
157440
2191
ja see on kujutis,
mille me robotiga saame.
mille me robotiga saame.
02:51
So we see the plastic pieces
floating slowly through the sensor,
floating slowly through the sensor,
54
159655
3721
Me näeme plasttükke
aeglaselt hõljumas sensorist mööda
aeglaselt hõljumas sensorist mööda
02:55
and the computer on board
will process this image,
will process this image,
55
163400
3296
ja pardakompuuter
töötleb seda kujutist
töötleb seda kujutist
02:58
and measure the size of each particle,
56
166720
2096
ja mõõdab iga osakese suurust,
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
seega saame ligikaudselt hinnata,
kui palju plastikut on vees.
kui palju plastikut on vees.
03:05
So we documented
this invention step by step
this invention step by step
58
173520
3016
Me dokumenteerisime
oma leiutise samm-sammult
oma leiutise samm-sammult
03:08
on a website for inventors
called Instructables,
called Instructables,
59
176560
3376
leiutajate veebilehel "Instructables"
03:11
in the hope that somebody
would make it even better.
would make it even better.
60
179960
2800
lootuses, et keegi teeb
seda veelgi paremaks.
seda veelgi paremaks.
Eriti äge selle projekti juures oli see,
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
et õpilased märkasid
oma kodukandis probleemi
oma kodukandis probleemi
03:19
and boom -- they are trying
to immediately address it.
to immediately address it.
62
187720
2667
ja plaksti! püüdsid seda
koheselt ka lahendada.
koheselt ka lahendada.
03:22
[I can investigate my local problem]
63
190411
2325
Minu õpilased Hong Kongis on
üli-informeeritud lapsed.
üli-informeeritud lapsed.
03:24
But my students in Hong Kong
are hyperconnected kids.
are hyperconnected kids.
64
192760
3216
03:28
And they watch the news,
they watch the Internet,
they watch the Internet,
65
196000
2296
Nad vaatavad uudiseid,
jälgivad internetti
jälgivad internetti
03:30
and they came across this image.
66
198320
2240
ja nad sattusid sellise pildi peale.
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
Seal oli laps, ilmselt alla 10-aastane,
puhastas paljakäsi naftaleket Sundarbansis
puhastas paljakäsi naftaleket Sundarbansis
03:38
in the Sundarbans, which is the world's
largest mangrove forest in Bangladesh.
largest mangrove forest in Bangladesh.
68
206600
4496
mis on maailma suurim
mangroovimets Bangladeshis.
mangroovimets Bangladeshis.
03:43
So they were very shocked,
69
211120
2456
Nad olid väga šokeeritud,
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
sest see on vesi, mida nad joovad,
vesi, milles nad end pesevad,
vesi, milles nad end pesevad,
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
see on vesi, millest nad püüavad kalu,
see on koht, kus nad elavad.
see on koht, kus nad elavad.
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
Ja te näete, et vesi on pruun,
muda on pruun ja nafta on pruun,
muda on pruun ja nafta on pruun,
seega, kui kõik on seal segunenud
03:56
so when everything is mixed up,
73
224240
1477
03:57
it's really hard to see
what's in the water.
what's in the water.
74
225741
2475
on raske näha, mis seal vees on.
04:00
But, there's a technology
that's rather simple,
that's rather simple,
75
228240
2256
Aga leidub üsna lihtne tehnoloogia,
04:02
that's called spectrometry,
76
230520
1536
mida nimetatakse spektromeetriaks,
04:04
that allows you see what's in the water.
77
232080
1905
ja mis võimaldab näha, mis vee sees on.
04:06
So we built a rough prototype
of a spectrometer,
of a spectrometer,
78
234009
3047
Niisiis tegime valmis lihtsa
spektromeetri prototüübi.
spektromeetri prototüübi.
04:09
and you can shine light
through different substances
through different substances
79
237080
2936
Sellega saab lasta valgust
läbi erinevate ainete,
läbi erinevate ainete,
04:12
that produce different spectrums,
80
240040
2416
mis tekitavad erinevaid spektreid,
04:14
so that can help you
identify what's in the water.
identify what's in the water.
81
242480
3856
ja sellega saab teha kindlaks,
mis seal vees sees leidub.
mis seal vees sees leidub.
04:18
So we packed this prototype of a sensor,
82
246360
2896
Pakkisime oma sensori prototüübi ära
04:21
and we shipped it to Bangladesh.
83
249280
2240
ja saatsime Bangladeshi.
04:23
So what was cool about this project
84
251989
1667
Selle projekti juures oli äge see,
04:25
was that beyond addressing
a local problem,
a local problem,
85
253680
3135
et lisaks kohaliku probleemi leidmisele
või kohaliku probleemiga tegelemisele,
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
kasutasid mu õpilased empaatiat ja loovust
04:34
to help, remotely, other kids.
88
262240
2256
et aidata lapsi, kes elasid palju kaugemal.
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
Ma tundsin edasisi eksperimente
tehes justkui kohustust
tehes justkui kohustust
04:40
and I wanted to take it even further --
91
268903
2513
asjaga veelgi põhjalikumalt tegeleda,
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
ja leida lahendus veelgi keerulisemale
probleemile, mis on mulle südamelähedane.
probleemile, mis on mulle südamelähedane.
04:48
So I'm half Japanese and half French,
93
276560
2616
Ma olen pool-jaapanlane, pool-prantslane,
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
ja kui te mäletate, siis aastal 2011
oli Jaapanis suur maavärin.
oli Jaapanis suur maavärin.
04:57
It was so violent that it triggered
several giant waves --
several giant waves --
95
285120
3816
See oli nii tugev, et tekitas
rea hiidlaineid,
rea hiidlaineid,
05:00
they are called tsunami --
96
288960
1416
mida nimetatakse tsunamiks -
05:02
and those tsunami destroyed many cities
on the eastern coast of Japan.
on the eastern coast of Japan.
97
290400
6960
ja need tsunamid hävitasid Jaapani
idarannikul mitmeid linnu.
idarannikul mitmeid linnu.
05:10
More than 14,000 people
died in an instant.
died in an instant.
98
298680
3360
Ühe hetkega hukkus üle 14 000 inimese.
05:15
Also, it damaged the nuclear
power plant of Fukushima,
power plant of Fukushima,
99
303600
3736
Lisaks sai kahjustusi
Fukushima aatomielektrijaam,
Fukushima aatomielektrijaam,
05:19
the nuclear power plant just by the water.
100
307360
2680
mis asub kohe mere ääres.
05:22
And today, I read the reports
101
310480
2416
Praegu loen ma raportitest,
05:24
and an average of 300 tons
102
312920
3056
et Vaiksesse ookeani
on tuumajaamast lekkinud
on tuumajaamast lekkinud
05:28
are leaking from the nuclear power plant
into the Pacific Ocean.
into the Pacific Ocean.
103
316000
3576
keskmiselt 300 tonni.
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
Terves Vaikses ookeanis on märke
tseesium-137 reostusest.
tseesium-137 reostusest.
05:38
If you go outside on the West Coast,
you can measure Fukushima everywhere.
you can measure Fukushima everywhere.
105
326000
4416
Kui minna läänerannikule,
siis on Fukushima tagajärjed
mõõdetavad kõikjal.
mõõdetavad kõikjal.
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
Vaadates seda kaarti võib paista
et enamik radioaktiivsusest
et enamik radioaktiivsusest
05:45
has been washed away
from the Japanese coast,
from the Japanese coast,
107
333760
2096
on Jaapani rannikult minema uhutud
ja suurem osa on nüüd -
paistab nüüd ohutu, see on sinine.
paistab nüüd ohutu, see on sinine.
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
05:50
Well, reality is a bit
more complicated than this.
more complicated than this.
109
338720
3416
Tegelikkus on veidi keerulisem.
05:54
So I've been going to Fukushima
every year since the accident,
every year since the accident,
110
342160
3656
Peale õnnetust olen ma
Fukushimas käinud igal aastal
Fukushimas käinud igal aastal
05:57
and I measure independently
and with other scientists,
and with other scientists,
111
345840
2536
ja mõõtnud nii sõltumatult
kui ka koos teiste teadlastega,
kui ka koos teiste teadlastega,
06:00
on land, in the river --
112
348400
1856
nii maismaal, kui ka jões -
06:02
and this time we wanted to take the kids.
113
350280
2736
ja seekord tahtsime lapsed kaasa võtta.
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
Loomulikult ei me lapsi kaasa ei võtnud,
vanemad poleks seda lubanud.
vanemad poleks seda lubanud.
(Naer)
06:08
(Laughter)
115
356840
1336
06:10
But every night we would report
to "Mission Control" --
to "Mission Control" --
116
358200
3936
Kuid igal õhtul me raporteerisime
juhtimiskeskusele -
juhtimiskeskusele -
06:14
different masks they're wearing.
117
362160
2176
nad kannavad erinevaid 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
Võib tunduda, et nad ei võtnud
seda tööd tõsiselt,
seda tööd tõsiselt,
aga tegelikult nad võtsid,
06:20
because they're going to have to live
with radioactivity their whole life.
with radioactivity their whole life.
119
368760
4200
sest neil tuleb selle radioaktiivsusega
elada kogu ülejäänud elu.
elada kogu ülejäänud elu.
06:25
And so what we did with them
120
373640
2056
Me tegime nendega seda,
et arutasime nendega andmeid,
mida päeva jooksul olime kogunud
mida päeva jooksul olime kogunud
06:27
is that we'd discuss the data
we collected that day,
we collected that day,
121
375720
2616
06:30
and talk about where
we should be going next --
we should be going next --
122
378360
2191
ja arutasime, kuhu
me peaksime edasi minema -
me peaksime edasi minema -
06:32
strategy, itinerary, etc...
123
380575
2121
strateegia, marsruut jne.
06:34
And to do this, we built
a very rough topographical map
a very rough topographical map
124
382720
3616
Ja selleks panime kokku
tuumajaama ümbruse
lihtstustatud topograafilise kaardi
lihtstustatud topograafilise kaardi
06:38
of the region around
the nuclear power plant.
the nuclear power plant.
125
386360
2856
06:41
And so we built the elevation map,
126
389240
2016
Ehitasime pinnavormidega mudeli,
06:43
we sprinkled pigments to represent
real-time data for radioactivity,
real-time data for radioactivity,
127
391280
4616
puistasime sellele värvainet,
et markeerida antud hetke
radioaktiivsuse taset
radioaktiivsuse taset
06:47
and we sprayed water
to simulate the rainfall.
to simulate the rainfall.
128
395920
4336
ja me pihutasime peale vett,
et imiteerida vihmasadu.
et imiteerida vihmasadu.
06:52
And with this we could see
that the radioactive dust
that the radioactive dust
129
400280
2976
Selle abil nägime, et radioaktiivne tolm
06:55
was washing from the top of the mountain
into the river system,
into the river system,
130
403280
3056
uhuti mäe otsast alla jõestikku,
06:58
and leaking into the ocean.
131
406360
1536
ja sealt lekkis ta ookeani.
06:59
So it was a rough estimate.
132
407920
1600
See oli esialgne hinnang.
07:02
But with this in mind,
we organized this expedition,
we organized this expedition,
133
410680
2936
Aga sellele mudelile tuginedes
korraldasime ekspeditsiooni,
korraldasime ekspeditsiooni,
07:05
which was the closest civilians have been
to the nuclear power plant.
to the nuclear power plant.
134
413640
3616
mis viis tsiviilisikud tuumajaamale
lähemale kui kunagi varem.
lähemale kui kunagi varem.
07:09
We are sailing 1.5 kilometers away
from the nuclear power plant,
from the nuclear power plant,
135
417280
4336
Olime merel 1.5 km tuumajaamast eemal
07:13
and with the help of the local fisherman,
136
421640
1953
ja kohalike kalurite abiga
07:15
we are collecting sediment from the seabed
137
423617
2239
kogusime merepõhjast setteid
spetsiaalse instrumendiga
spetsiaalse instrumendiga
07:17
with a custom sediment sampler
we've invented and built.
we've invented and built.
138
425880
3456
mille olime ise leiutanud
ja valmis teinud.
ja valmis teinud.
07:21
We pack the sediment into small bags,
139
429360
3256
Pakkisime setted väikestesse kottidesse,
07:24
we then dispatch them
to hundreds of small bags
to hundreds of small bags
140
432640
2256
jagasime need omakorda sadadesse
väiksematesse kotikestesse,
väiksematesse kotikestesse,
07:26
that we send to different universities,
141
434920
1936
ja saatsime erinevatele ülikoolidele.
07:28
and we produce the map
of the seabed radioactivity,
of the seabed radioactivity,
142
436880
2976
Panime kokku merepõhja
radioaktiivsuse kaardi,
radioaktiivsuse kaardi,
07:31
especially in estuaries
where the fish will reproduce,
where the fish will reproduce,
143
439880
2536
eriti jõesuudmete osas,
kus on kalade paljunemiskoht
kus on kalade paljunemiskoht
07:34
and I will hope that we will have improved
144
442440
2056
ja ma loodan, et tänu sellele
on paranenud
on paranenud
07:36
the safety of the local fishermen
and of your favorite sushi.
and of your favorite sushi.
145
444520
3096
nii kohalike kalurite
kui ka teie lemmiksushi ohutus.
kui ka teie lemmiksushi ohutus.
(Naer)
07:39
(Laughter)
146
447640
1296
Näete siin arengut -
07:40
You can see a progression here --
147
448960
1576
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
läksime kohaliku probleemi juurest edasi
ja jõudsime globaalse probleemini.
ja jõudsime globaalse probleemini.
07:47
And it's been super exciting
to work at these different scales,
to work at these different scales,
149
455120
2953
On olnud ülipõnev töötada
erinevates mastaapides projektidega,
erinevates mastaapides projektidega,
07:50
with also very simple,
open-source technologies.
open-source technologies.
150
458097
3559
tehes seda väga lihtsate,
vabavaraliste tehnoloogiatega.
vabavaraliste tehnoloogiatega.
07:53
But at the same time,
it's been increasingly frustrating
it's been increasingly frustrating
151
461680
3336
Kuid samal ajal on see olnud
järjest masendavam
järjest masendavam
07:57
because we have only started to measure
the damage that we have done.
the damage that we have done.
152
465040
3696
sest oleme tekitatud kahju
tuvastamisega alles päris alguses.
tuvastamisega alles päris alguses.
08:00
We haven't even started
to try to solve the problems.
to try to solve the problems.
153
468760
4080
Me pole probleemide
lahendamisega veel alustanudki.
lahendamisega veel alustanudki.
08:05
And so I wonder
if we should just take a leap
if we should just take a leap
154
473640
2776
Ja nii ma mõtlen, et kas ei tuleks
võtta asja ette hoopis suuremalt
võtta asja ette hoopis suuremalt
08:08
and try to invent better ways
to do all these things.
to do all these things.
155
476440
4640
ja püüda välja mõelda paremaid meetodeid,
kuidas seda kõike teha.
kuidas seda kõike teha.
08:13
And so the classroom
started to feel a little bit small,
started to feel a little bit small,
156
481520
3576
Nii jäigi klassiruum natuke väikseks
08:17
so we found an industrial
site in Hong Kong,
site in Hong Kong,
157
485120
2696
ja leidsime ühe tööstushoone Hong Kongis
08:19
and we turned it into
the largest mega-space
the largest mega-space
158
487840
3256
ning muutsime selle
suurimaks töökojaks,
suurimaks töökojaks,
08:23
focused on social
and environmental impact.
and environmental impact.
159
491120
3176
mis on keskendunud
sotsiaalsele ja keskkonnamõjule.
sotsiaalsele ja keskkonnamõjule.
See asub Hong Kongi kesklinnas,
08:26
It's in central Hong Kong,
160
494320
1296
08:27
and it's a place we can work
with wood, metal, chemistry,
with wood, metal, chemistry,
161
495640
3216
ja seal saame töötada
puidu, metalli ja kemikaalidega,
puidu, metalli ja kemikaalidega,
08:30
a bit of biology, a bit of optics,
162
498880
1626
natuke bioloogiat, natuke optikat,
08:32
basically you can build
pretty much everything there.
pretty much everything there.
163
500530
2492
põhimõtteliselt on seal võimalik
ehitada kõike, mis pähe tuleb.
ehitada kõike, mis pähe tuleb.
See on koht, kus täiskasvanud
ja lapsed saavad koos mängida.
ja lapsed saavad koos mängida.
08:35
And its a place where
adults and kids can play together.
adults and kids can play together.
164
503047
2969
08:38
It's a place where
kids' dreams can come true,
kids' dreams can come true,
165
506040
3576
Koht, kus laste unistused saavad tõeks,
08:41
with the help of adults,
166
509640
1336
täiskasvanute abiga,
08:43
and where adults can be kids again.
167
511000
1816
ja kus täiskasvanud saavad
olla jälle lapsed.
olla jälle lapsed.
08:44
Student: Acceleration! Acceleration!
168
512840
3136
Uurime igasuguseid küsimusi:
08:48
Cesar Harada: We're asking
questions such as,
questions such as,
169
516000
2135
kas saab leiutada liikluse tulevikku
taaskasutatava energiaga,
taaskasutatava energiaga,
08:50
can we invent the future of mobility
with renewable energy?
with renewable energy?
170
518159
2817
näiteks.
08:53
For example.
171
521000
1200
Või, kas me suudame aidata
vananevat rahvastikku liikumise osas
vananevat rahvastikku liikumise osas
08:55
Or, can we help the mobility
of the aging population
of the aging population
172
523320
4296
08:59
by transforming very standard wheelchairs
into cool, electric vehicles?
into cool, electric vehicles?
173
527640
4400
muutes tüüpilised ratastoolid
ägedateks elektrisõidukiteks?
ägedateks elektrisõidukiteks?
09:05
So plastic, oil and radioactivity
are horrible, horrible legacies,
are horrible, horrible legacies,
174
533240
6536
Plastmass, nafta ja radioaktiivsus
on hirmsad pärandid,
on hirmsad pärandid,
aga kõige hirmsam pärand, mida saame
lastele jätta, on valed.
lastele jätta, on valed.
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
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
Meil pole enam võimalik
varjata laste eest inetut tõde,
varjata laste eest inetut tõde,
09:22
because we need their imagination
to invent the solutions.
to invent the solutions.
177
550000
3920
sest meil on vaja nende kujutlusvõimet,
et leiutada lahendusi.
et leiutada lahendusi.
09:26
So citizen scientists, makers, dreamers --
178
554720
4976
Vastutustundlikud leiutajad,
loojad, unistajad -
loojad, unistajad -
09:31
we must prepare the next generation
179
559720
2696
me peame ette valmistama
järgmise põlvkonna,
järgmise põlvkonna,
09:34
that cares about
the environment and people,
the environment and people,
180
562440
3056
kes hoolib keskkonnast ja inimestest,
09:37
and that can actually
do something about it.
do something about it.
181
565520
2200
ja kes suudab selle heaks
ka midagi ära teha.
ka midagi ära teha.
09:40
Thank you.

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.
