In One Glance

Coral reefs are ecosystems formed by coral colonies. Corals build calcium carbonate skeletons that create complex reef structures over long time periods. Reefs provide habitat, shelter, and feeding grounds for many species and support biodiversity. They are sensitive to changes in temperature and water quality, so protecting reefs means protecting ocean health. The story presents reefs as peaceful underwater neighborhoods and emphasizes gentle care.
