With its white sand beaches and its waves that are popular among the surfers, but also its Great Barrier Reef, Australia has all of heaven on Earth. Its inhabitants have well understood that and have built their lives facing the ocean they cherish. But extreme climate phenomena undermine the balance of the country. The Great Barrier Reef is affected by another episode of severe bleaching. In thirty years, almost half of this heritage has been lost, and the reefs could disappear forever.
