Have you ever been scuba diving or snorkeling? Okinawa is famous for its coral reefs, which are made up of trillions and trillions of tiny animals. When one of these tiny animals dies, its skeleton joins with other skeletons, which build up little by little. It takes a long time, though, because coral only grows between 3 and 2 centimeters a year. When you think about how long it takes for them to grow, it’s no wonder that people are always advocating for more care so the reefs aren’t damaged. (by Prof. Carmella Lieske)
