Coral reefs are dying around the world. [1] Human activities have substantial impact on coral reefs, contributing to their worldwide decline. [2] Damaging activities encompass coral mining, pollution (both organic and non-organic), overfishing, blast fishing, as well as the excavation of canals and access points to islands and bays.
One-fifth of coral reefs have also been destroyed, and another fifth has been severely degraded by overfishing, pollution, and invasive species; 90% of the Philippines' coral reefs alone have been destroyed. [16] Finally, over 35% of the mangrove ecosystems worldwide have been destroyed. [16]
A science dive on coral reefs in Karimunjawa. Coral reef restoration strategies use natural and anthropogenic processes to restore damaged coral reefs. [1] Reefs suffer damage from a number of natural and man-made causes, and efforts are being made to rectify the damage and restore the reefs.
Southeast Asia's coral reefs make up over a third of the world's coral reefs and are part of the ‘Coral Triangle', a richly biodiverse marine area that generally stretches from the Philippines to Indonesia to the Solomon Islands. But most of these are now at risk of being destroyed.
Coral reefs are home to roughly a quarter of all marine life, and they provide a natural barrier against storms. But they’re sensitive to temperature, and scientists have long worried they’d ...
Coral reefs cover less than one percent of the ocean floor, but have out-sized benefits for marine ecosystems and economies. A quarter of marine life will depend on reefs for shelter, finding food ...
Coral reefs flourish in ocean waters that provide few nutrients. They are most commonly found at shallow depths in tropical waters, but deep water and cold water coral reefs exist on smaller scales in other areas. Shallow tropical coral reefs have declined by 50% since 1950, partly because they are sensitive to water conditions. [9]
While the Caribbean coral reefs were devastated during the record high water temperatures last year, “2023 wasn't as bad as we feared in the rest of the world,” Eakin said.
