When dive centre OK Divers posted photos of a coral that has been intentionally defaced with words and names etched into it, people were absolutely outraged. As the post went viral, the divers used the opportunity to send an important message: "Like many of you, we believe that their dive guide should have known better than to let them do this," OK Divers said. "Nonetheless, the diver has come forward, they are truly sorry. Even though it won't help the coral, we appreciate their honesty and believe they have learned a lesson they will never forget ... [we ask you to] think of what we all can do to prevent such things from happening and how we can protect the precious underwater world."
