UNEP Emerging Issues: Environmental Consequences of Ocean Acidification: A Threat to Food Security

Carbon dioxide is altering the chemistry of the surface oceans and causing them to become more acidic. From scientists and marine resource managers, to policy and decision-makers, there is growing concern that the process called ocean acidification could have significant consequences on marine organisms which may alter species composition, disrupt marine food webs and ecosystems and potentially damage fishing, tourism and other human activities connected to the seas.
