When the phenomenon OCEAN ACIDIFICATION It will result in many kinds of marine animals such as corals that rely on carbonate ion (CO32-) and calcium ions. (Ca2 +) to create a hard shell and structure (skeletons) higher acidity of the water will reduce the amount of carbonate ions are used to. Skeletons of coral growth. The acidity of seawater rises, it melts the skeletons. The weathering of the layout of the solid calcium carbonate. Coral, structural integrity, as well, and when this happens area. Coastal reefs are destroyed will be severely eroded by the rough sea in the monsoon season due to lack of coastal and coral reef wall. Help prevent coastal erosion from waves and tides, resulting in a direct line. Coral, which is a source of food for humans and is also the habitat of animals and plant species that live only in coral reefs, such as sea turtles and invertebrates such as squid, mussels, shrimp, jellyfish and sea cucumbers and so on plankton or sea monster size. Small residential and propagated. No reefs, coral reefs are the species that will result in the food chain. It may make sea creatures in the sea with a large starvation and the death. The direct impact on humans, which is about a food fishery.
