Citizen Science is approaching the mysteries of coral, and this summer, “Find out what coral likes! EXPO EDITION” is a special program that allows everyone to become a researcher. “What do corals like to eat?” “Do they accidentally eat microplastics?” Come up with a hypothesis and try to answer such questions. You can actually feed corals, carefully observe their feeding behavior, and even collect data, giving you a full-fledged researcher experience. Your discoveries will become valuable data that will be published as the world’s first citizen science paper, and may contribute to the problem of marine pollution, becoming a big step towards protecting the future of our oceans.
