'Reef stars' promote new growth in Bali's dying coral ecosystem

Using a snorkel and protective gloves, Pariama Hutasoit dives down into the clear waters off the Indonesian island of Bali to pull away plastic from a "reef star" installed by her conservation group to encourage new coral growth. The Nusa Dua Foundation has installed almost 6,000 of the stars, hexagonal-shaped steel structures around a meter in diameter, in coral reefs across Bali. The stars bridge gaps in the reefs where coral has died, supporting regrowth.
