ScienceIndia’s disappearing islands turn to seagrass to fight rising seas

Kariyachalli, one of 21 islands off India’s Tamil Nadu coast, has lost more than 80 percent of its land over the past 50 years because of coral mining, bleaching and rising seas. Scientists warn it could disappear by 2036 without action. Residents and marine researchers are restoring seagrass and coral reefs to build natural barriers that protect the island and the coastal economy.
