my parents would tell me,
but you have to clean up after yourself."
後で自分でちゃんと片付けなさい」
to all these wonderful places,
素晴らしい世界ばかり
育ったのです
良いかもしれません
to protect us from the ugly truth.
ウソをつくからです
that adults make a mess,
大人達が散らかしておいて
at cleaning up after themselves.
気付くようになりました
私は香港ハーバースクールで
at the Hong Kong Harbour School.
科学と発明の仕方を教えています
and stumble upon piles of trash.
ゴミの山に出会いました
we clean up the beaches --
私たちは海岸の清掃をしました
and if he is, I did not give it to him.
飲んでたとしても私が渡したんじゃありません
of the oceans have plastic in them.
とても残念なことで
and those big nets,
大きな船を出して
that we look at under a microscope,
プロットしてきました
時間と費用がかかります
it's very expensive,
to take those big boats out.
リスクが高いのです
生徒達といっしょに
of inventing a better way.
考え出したいと思い
Hong Kong classroom into a workshop.
工作室に変えました
作業台づくりから始めました
this small workbench,
小さな子供も参加できるようにしてあります
so even really short kids can participate.
are awesome and safe.
まったくもって安全 —
to the size we find it in the ocean,
細かく砕きました
because it breaks down.
of my students run wild.
自由に羽ばたかせてもらいます
the best of each kid's idea
良い部分を取って組み合わせ
that hopefully would work.
まとめ上げることです
that instead of collecting plastic bits,
回収する代わりに
ロボットで把握しようというわけです
of the plastic with a robot --
子供達は夢中になります
we do what we call "rapid prototyping."
when we're hacking it.
まだ中身が残っています
into plumbing fixtures
配管に組み込んで
that will be slowly moving through water
ゆっくり動き回る
that we have there --
that we get in the robot.
ゆっくり通り過ぎています
floating slowly through the sensor,
画像処理して
will process this image,
大きさを測定し
総量を推計します
of how much plastic there is in the water.
this invention step by step
詳しく載せました
called Instructables,
would make it even better.
ことを期待しています
was that the students saw a local problem,
子供達が何か身近な問題を目にして
to immediately address it.
すぐに取り組んでいることです
ものすごく情報に通じています
are hyperconnected kids.
they watch the Internet,
よく見ています
cleaning up an oil spill bare-handed,

世界最大のマングローブ林がある場所です
this is the water they bathe in,
this is the place where they live.
生活の場だからです
the mud is brown and oil is brown,
茶色をしていて

that's rather simple,
良い方法があります
分かるようにしてくれます

a local problem,

and their sense of being creative
他の子供達のことを心配し
していることです
by doing the second experiments,
と思いました
and it's also closer to my heart.
思い入れの深い問題に向けてです
半分フランス人ですが
there was a massive earthquake in Japan.
皆さん覚えているでしょうか?
several giant waves --
on the eastern coast of Japan.
多大な被害をもたらしました

瞬く間に失われました

原子力発電所にも
into the Pacific Ocean.
流出しました

セシウム137による汚染の痕跡が見られます
you can measure Fukushima everywhere.
どこでも福島の影響を観察できます
it can look like most of the radioactivity
日本の沿岸から洗い流されており
from the Japanese coast,
it looks like it's safe, it's blue.
more complicated than this.
every year since the accident,
福島を訪れています
and with other scientists,
独自に測定しています
連れて行きたいと思いました
the parents wouldn't allow that to happen.
連れては行きませんでしたけど
to "Mission Control" --
報告を入れました
かぶっています
the work seriously, but they really did
子供達は本当に真剣に考えています
with radioactivity their whole life.
いかなければならないからです
we collected that day,
話し合いました
we should be going next --
a very rough topographical map
the nuclear power plant.
地形図を作成しました
顔料をふりまき
real-time data for radioactivity,
to simulate the rainfall.
霧吹きで吹きかけました
that the radioactive dust
放射性の塵が
into the river system,
さらに海へと
見て取れました
推定ということです
we organized this expedition,
調査旅行を計画し
原子力発電所の近くに行くことにしました
to the nuclear power plant.
from the nuclear power plant,
船で行ったんです
協力していただいて
標本採集器で
we've invented and built.
to hundreds of small bags
of the seabed radioactivity,

and of your favorite sushi.
願っています
見て取れると思います
to a remote problem to a global problem.
さらに地球規模の問題へと
to work at these different scales,
とてもワクワクします
open-source technologies.
it's been increasingly frustrating
感じるようにもなりました
the damage that we have done.
測定し始めただけで
to try to solve the problems.
いないからです
if we should just take a leap
to do all these things.
という思いを抱いていました
started to feel a little bit small,
ようになったので
site in Hong Kong,
the largest mega-space
フォーカスした
and environmental impact.
変えました
with wood, metal, chemistry,
光学まで使い
そこで作ることができます
pretty much everything there.
一緒になって遊べる場所です
adults and kids can play together.
kids' dreams can come true,
できる場所です
questions such as,
with renewable energy?
of the aging population
作り変えられないだろうかと
into cool, electric vehicles?
are horrible, horrible legacies,
大きな負の遺産ですが
それは「ウソ」だと思います
that we can leave our children is lies.
to shield the kids from the ugly truth
守っている余裕はありません
to invent the solutions.
子供達の想像力が必要だからです
夢を持つ者である私達は
the environment and people,
ならないのです
do something about it.
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.
