By Anna VodickaOn Peleliu, the roads are paved with coral—a once-living thing, a hardy animal. The coral came from the inland ridges and valleys of this two-by-six-mile speck among specks in the island nation of Palau, in western Micronesia, an almost invisible scene in the shadow of bigger acts in the Pacific, where land itself is a kind of debris, cast from the ocean by tectonic clashes and shifts that left things topsy-turvy, bottom-up, fish-out-of-water. Before: an underwater reef, an ecosystem of competitive individuals. After: a coral atoll bleaching into a future island paradise. Something new under the sun.
