"From the Ted Talk by Kristen Marhaver: Why I still have hope for coral reefs"

Unscramble the Blue Letters

Let's consult a graph. Since the invention of scuba, scientists have measured the anumot of coral on the sloaefor, and how it's changed through time. And after centuries of ratcheting human pressure, Caribbean reefs met one of three fteas. Some reefs lost their calors very quickly. Some refes lost their corals more slowly, but kind of ended up in the same place. OK, so far this is not going very well. But some reefs in the Caribbean — the ones best protected and the ones a little further from humans — they managed to hold onto their corals. Give us a challenge. And, we almost never saw a reef hit zero.

Original Text

Let's consult a graph. Since the invention of scuba, scientists have measured the amount of coral on the seafloor, and how it's changed through time. And after centuries of ratcheting human pressure, Caribbean reefs met one of three fates. Some reefs lost their corals very quickly. Some reefs lost their corals more slowly, but kind of ended up in the same place. OK, so far this is not going very well. But some reefs in the Caribbean — the ones best protected and the ones a little further from humans — they managed to hold onto their corals. Give us a challenge. And, we almost never saw a reef hit zero.
