Ocean acidification is a global issue, which is affecting all ocean regions. It is important as it may have severe impacts on marine organisms and ecosystems. Loss of biodiversity is a likely result, accompanied by a reduction of harvestable resources, including those associated with human food resources. If CO2 emissions continue at the same rate, ocean acidification will have a considerable influence on marine-based diets for billions of people worldwide. The only way to stop ocean acidification is to curb emissions of CO2.
