The world has lost 30 to 50 percent of its coral reefs already. Without significant intervention, tropical reef ecosystems could face global extinction by the end of the century. A Plan to Save Coral Reefs. Saving and restoring the world's coral reefs requires a multi-pronged approach that ranges from the local to the global level.

Biodiversity. Biodiversity refers to the variety of living species that can be found in a particular place. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all ...
8 de dic. de 2019 · Scientists estimate that at current rates of decline, most of the world's coral reefs will be completely destroyed in the next few decades. [4] Over 80% of the world's shallow coral reefs are overfished. [4] Tropical coral reefs border around 109 countries. However, dramatic reef degradation has occurred in 93 of these countries. [2]
24 de feb. de 2024 · Coral reefs play a crucial role in the formation of other ecosystems. For example, parrotfish graze on coral formations, leading to the creation of sandy areas. These sands, influenced by currents, contribute to the formation of islands, shallows, and eventually mangroves and coastal forests. 6. How do coral reefs protect coastal ecosystems and ...
37% of fish are associated with tropical reef environments. Recent estimates suggest that more than 90% of coral reef species have not been named and that total reef species numbers exceed 800,000. This level of diversity is particularly impressive given that reefs only cover about 285,000 km2, which is less than 0.1% of the surface area of the ocean. . . read more
Types of Coral Reef Formations. Scientists generally agree on four different coral reef classifications: fringing reefs, barrier reefs, atolls, and patch reefs. Fringing reefs grow near the coastline around islands and continents. They are separated from the shore by narrow, shallow lagoons. Fringing reefs are the most common type of reef.
