We had a bleaching event in 2010 in the Caribbean that took off big patches of skin on boulder corals like these.
加勒比海在2010年也經歷了白化事件，當時就像這樣大片大片的珊瑚礁表面被剝離了。
This coral lost half of its skin. But if you look at the side of this coral a few years later, this coral is actually healthy again.
一般的珊瑚表面沒有了。但是如果你在幾年之后觀察同一處珊瑚，珊瑚實際上重新恢復了健康。
It's doing what a healthy coral does. It's making copies of its polyps, it's fighting back the algae and it's reclaiming its territory.
它像正常的珊瑚礁一樣。它復制自己的息肉，它向藻類回擊，重新奪回自己的領地。
If a few polyps survive, a coral can regrow; it just needs time and protection and a reasonable temperature.
如果有少量息肉存活，一片珊瑚就可以再生；它僅僅需要時間、適當的保護以及合理的海水溫度。
Some corals can regrow in 10 years -- others take a lot longer. But the more stresses we take off them locally,
有些珊瑚可以在10年內再生——其它的會稍微長一點。但是我們在珊瑚礁周邊給珊瑚礁的壓力，
things like overfishing, sewage pollution, fertilizer pollution, dredging, coastal construction,
像是過度捕撈、生活污水和農業肥料污染等，清淤工程、海岸建設，
the better they can hang on as we stabilize the climate, and the faster they can regrow.
當我們將氣候穩定后這些問題處理的愈好，珊瑚的恢復速度就越快。
And as we go through the long, tough and necessary process of stabilizing the climate of planet Earth, some new corals will still be born.
在我們完成這個漫長、艱難而又必需的目標時也就是讓地球的氣候恢復穩定，一些新的珊瑚會繼續誕生。
This is what I study in my research. We try to understand how corals make babies, and how those babies find their way to the reef,
這是我的研究內容。我們嘗試理解珊瑚如何產生小珊瑚，以及這些小寶寶如何能夠尋找到珊瑚礁，
and we invent new methods to help them survive those early, fragile life stages.
然后我們發明新的方法幫助他們存活，挺過生命初期的脆弱階段。
