There is exactly one in the South Atlantic. It sits 266 kilometers northeast of Natal, a coral ring drawn on the flat summit of a drowned volcano, rising from nearly a kilometer of water to within three meters of the surface. Ships passing too close in the age of sail did not always see it in time. Now, almost no ship passes close at all. Atol das Rocas is Brazil's first marine biological reserve, a place where scientists go only with permission, where tourists never go at all, and where roughly 143,000 seabirds make their nests in a silence almost unbroken by humans.

As the summit subsided, coral grew upward to stay in the sunlight near the surface, layer on layer, unt...

Standing beside it at dawn, you see the ring of reef catch the first light before the rest of the ...
