how does ocean acidification affect the community?
189454
Ocean acidification will affect humans too! It will affect the food we eat since most of our shellfish requires calcium carbonate to form or to fortify their shells. ... The presence of healthy coral reefs is imperative to our survival because we rely on them for food, coastal protection, medicines and tourism dollars.

Rising ocean temperatures and ocean acidification are radically altering marine aquatic ecosystems, while freshwater ecosystems are being impacted by changes in water temperature, water flow, and fish habitat loss. Climate change is modifying fish distribution and the productivity of marine and freshwater species.

Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water's pH, making the ocean more acidic. Many factors contribute to rising carbon dioxide levels.
263408
The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. ... In the center of the ocean, wind-driven currents bring cool waters and fresh carbonate to the surface.
1081162
As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance. But this absorption has a price: these reactions lower the water's pH, meaning it's more acidic.
309979
The rising concentration of carbon dioxide in the atmosphere is driving up ocean surface temperatures and causing ocean acidification. ... The rate at which water absorbs CO2 decreases as water temperature increases.
372979
Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. ... Oceans are becoming more acidic.
211557
Climate change dramatically affects coral reef ecosystems Climate change leads to: A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. ... Ocean acidification (a result of increased CO2): causes a reduction in pH levels which decreases coral growth and structural integrity.
1078899
The increase of carbonic acid in the oceans inhibits growth and development of marine life. ... Rising oceanic acidification can inhibit growth of sea-urchins and other organisms like them that require calcium to maintain their exoskeleton. Increase of carbonic acid in water can lead to low levels of calcium in water.
59436
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
403644
All phytoplankton and higher plants perform photosynthesis, where carbon dioxide is incorporated into biomass during cell growth. Ocean acidification (OA) has the potential to affect photosynthetic kinetics due to increasing seawater pCO2 levels and lower pH.
351453
Ocean acidification threatens the Great Barrier Reef by reducing the viability and strength of coral reefs. ... Ocean acidification results from a rise in atmospheric carbon dioxide, which is taken up by the ocean. This process can increase sea surface temperature, decrease aragonite, and lower the pH of the ocean.
649361
To get the energy algae need to survive, they use carbon dioxide for photosynthesis. Yet, too much carbon dioxide in the ocean causes the water to become acidic, a process called ocean acidification. ... Algae can release enzymes into the water that can help quickly break down carbon dioxide into bicarbonate ions.
261340
Increasing ocean acidity interferes with the metabolism and reproduction of marine organisms that have calcium carbonate shells such as corals and sea urchins, threatening both ocean food chains and the shellfish industries and economies of West Coast states.
1063857
Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. ... Deforestation results in fewer trees to absorb the gas. Also, when plants are cut down and burnt or left to rot, the carbon that makes up their organic tissue is released as carbon dioxide.

Effects of Climate Change on Marine Life. Marine life faces challenges from warming waters and ocean acidification. Warming waters alter the latitude and depth at which certain species are able to survive, so many species are moving deeper or father north in the Atlantic to find cold water.
484983
Oceans absorb about one-fourth of the CO2 that the world emits into the atmosphere, changing seawater chemistry and, in turn, some marine ecosystems and organisms. ... Ocean acidification makes it harder for clams and mussels to find the material they need to build and maintain their calcium carbonate shells.
