푹 빠지신 분 계신가요?
of an individual raising a hand
in a social network
공통적으로 우선시하는 것이 있습니다.
이득이라는 것이죠.
like the cool kids made you "cool."
옷을 입으면 "멋져" 보인다고 믿었죠.

흔히 관찰할 수 있습니다.
copy the alarm calls of other birds
다가올 때 경고하는 울음을 냅니다.
about approaching predators.
위험하다는 정보를 퍼뜨리죠.
that we humans depend on?
영향을 줄 수 있을까요?
while studying coral reefs,
이런 의문이 들었습니다.
through fisheries and tourism
수백만 명의 삶을 지탱합니다.
by eating algae.
and take over entire coral reefs,
산호초 군락을 차지해버립니다.
or impossible to reverse.
큰 손실이 발생합니다.
how fish may prevent this,
보호하는 법을 알고 싶었습니다.
어류의 행동을 조용히 관찰했죠.
exposed to predators,
먹기란 어려웠을 겁니다.
눈치챈 녀석도 있었죠.
how these fish do their job
어떻게 움직이는지 궁금했습니다.

비디오 카메라 설치대를 두고
원격으로 관찰했습니다.
and precise movements
정확한 움직임을 볼 수 있었습니다.
thousands of fish movements
from different species

and ate more algae
섭취하는 물고기가 많을수록
by more feeding fish.
더 많은 해조류를 먹었습니다.
by individual fish
vital information.
전달되고 있었던 거죠.

can show others that the coast is clear.
무사히 들어왔다면,
these fish are different species,
안전하다고 느끼죠.
사회적 관계로 연결되어 있어서
on when it's safe to eat.
정보를 주고받습니다.
copying other fish in their social network
섭취하는 해조류의 양은
of the algae eaten by the fish community,
60% 이상을 차지합니다.

에너지 및 자원의 흐름에
that overfishing,
the social network of remaining fish,
파괴한다는 점을 시사합니다.
해조류를 덜 섭취하게 되죠.
critical information.
교환하지 못했기 때문입니다.
more vulnerable than we currently predict.
산호초가 더 취약해질 수 있습니다.
다수에게 전파하고
인류에게 식량을 제공하고,
points us towards better ways
지속 가능한 산호초 관리를 향한

영향을 받는 것이 아니라
by the actions of individual fish

Why you should listen
Marine biologist, National Geographic Explorer and TED Fellow Mike Gil conducts field experiments and builds mathematical models to understand how marine ecosystems function. This understanding, he says, is crucial for humankind to build a sustainable future. Gil has led research around the world: from coral reefs in the Caribbean, French Polynesia and Southeast Asia, to "microislands" of plastic garbage, teeming with life, in the middle of the Pacific. Currently, Gil uses novel multi-camera systems in the field combined with computer vision technology to explore, at an unprecedented scale and resolution, how coral reef fish behave, socialize and affect entire coral reef ecosystems. Gil's scientific discoveries and his often unorthodox approaches have garnered significant national and international media attention.
In addition to being a National Science Foundation Postdoctoral Research Fellow at the University of California, Davis, Gil is also an avid and award-winning science communicator. As a self-described "science-hater turned scientist" from humble beginnings, he is passionate about diversity and inclusion in STEM fields. To this end, Gil founded and runs the nonprofit SciAll.org, which uses free online videos to bring mass public audiences along for the adventures that come with a career in science. Through his research and outreach, Gil aims to deliver a timely message to humanity: science is exhilarating, accessible and in the service of all.
