Coral Reefs: Why They Matter Beyond Tourism

Coral reefs protect shorelines, support fisheries, and sustain biodiversity, far beyond their postcard beauty.

Coral reefs are often called the rainforests of the sea because they host extraordinary biodiversity. Even though they cover a small part of the ocean floor, they provide shelter, breeding grounds, and food for countless species.

Their value is not only ecological. Reefs act as natural breakwaters that reduce wave energy, helping protect coasts from erosion and storm damage. In many regions, they reduce disaster costs and protect homes, roads, and ports.

Reefs are under stress from warming waters, acidification, and pollution. Conservation is most effective when local action and global policy work together: reducing runoff, improving wastewater treatment, and cutting greenhouse gas emissions at scale.
