Ocean acidification is an indicator of climate change and it is the one aspect of global climate change. Human activities have led to the emission of large amounts of carbon dioxide into the atmosphere and with high carbon dioxide levels, the oceans develop low levels of aragonite saturation levels, making it difficult for some organisms to build and maintain their shells or skeletons. Extinction has been linked to the present rate of change in ocean water chemistry. Ocean acidification has a lasting impact on ecosystem services such as food security through endangering aquaculture and fisheries; it impairs the ocean's capacity to absorb and store greenhouse gas and regulate climate change.
