Report warns coral reefs covering 1% of oceans face irreversible decline

Coral reefs, covering only about one percent of the world’s ocean surface, support an estimated 25 percent of marine species, according to recent ecological assessments. This disproportionate concentration of biodiversity makes reefs a critical component of oceanic ecosystems, providing habitat, feeding grounds, and breeding sites for a wide array of fish, invertebrates, and other marine organisms.

Scientists emphasize that the ecological value of reefs extends beyond wildlife, influencing fisheries, tourism, and coastal protection for millions of people. Ongoing pressures such as climate‑induced bleaching, ocean acidification, overfishing, and pollution threaten the resilience of these habitats. International conservation initiatives are therefore focusing on reducing stressors and enhancing reef restoration to preserve their biological richness and the services they deliver to both marine life and human communities.
