Anuar Abdullah has always had a special feeling for the ocean. In the 1980s, he settled in Perhentian as a diving instructor and fell in love with corals. Twice daily, he went out to sea, staying underwater for as long as his oxygen supply allowed. He learned the shapes and textures(纹理) of coral reefs long before he knew their Latin names. He studied the living conditions—the water temperature, the sunshine, the diversity(多样性) of ocean life—and saw how just one of those factors could bring about large-scale death.

Abdullah spent two decades experimenting with how to grow coral reefs in the ocean. He didn't have a degree in marine (海洋的) biology or a research lab, but he had his own ways. Almost all the materials he used to grow corals came directly from the ocean. He didn't use steel pipes or bricks—which he couldn't afford—instead, he gathered rocks from the seafloor, piling them so they wouldn't be knocked down by tidal waves. While others might depend on a lab to break live coral into pieces that were in turn used for growing, he searched for broken pieces of coral in existing reefs and fixed them to the rocks using animal-friendly glue. When he needed other materials, he started by searching the beach for waste.

Every day, the locals saw him on his knees examining corals in the ocean. Sometimes, he picked up a rock to which he had fixed a piece of coral several weeks earlier, and said very quietly, "My little acropora (鹿角大珊瑚), how are you doing today?" The locals whispered about how he'd spent days in the water speaking to corals as if they were people. "Everyone thought I was stupid," said Abdullah, "But I knew I was doing the most important thing in the world."

Actually, Abdullah was right. Now, in a world rapidly losing its coral reefs to climate change and environmental damage, he has become an increasingly influential expert on how to bring them back to life. Thousands have traveled from around the world to learn from Abdullah how to grow corals, with some eventually leaving their jobs to join his projects full time. With his 700 active volunteers, he has already saved about 125 acres of coral reefs
