Coral reefs are dying worldwide, and we’re losing some of the world’s richest habitats. But the Associated Press reports that one team of scientists have discovered a way to bring them back.

What Goreau’s Bali project has done is to construct metal frames, often in the shape of domes or greenhouses, and submerge them in the bay. When hooked up to a low-voltage energy source on the shore, limestone — a building block of reefs — naturally gathers on the metal. Workers then salvage coral that has broken from damaged reefs and affix it to the structure.

The project is still small, but shows promise to help us rebuild our coral reefs.

Scientists care.
