In tourism-dependent Caribbean, efforts to restore mostly dead coral reefs increasing

ORACABESSA BAY, Jamaica –  Mats of algae and seaweed have shrouded the once thick coral in shallow reefs off Jamaica's north coast. Warm ocean waters have bleached out the coral, and in a cascade of ecological decline, the sea urchins and plant-eating reef fish have mostly vanished, replaced by snails and worms that bore through coral skeletons.

Now, off the shores of Jamaica, as well as in Caribbean islands from Bonaire to St. Croix, conservationists are planting fast-growing coral species to try and turn things around by "seeding" reefs.

The strategy has doubters, with one expert joking that prayer might be as effective, but conservationists say the problem is so catastrophic that inaction is not an option. According to the International Union for Conservation of Nature, live coral coverage on Caribbean reefs is down to an average of just 8 percent, from 50 percent in the 1970s.
