Analysis: The chemistry of ocean pH and ‘acidification’ ‘There are reasons to assume that marine life will not be overly affected by an increase in ocean acidity due to atmospheric CO2’
'Ocean life evolved and survived far higher levels of CO2 for millions of years in the past. Marine organisms actively create carbonate shells (using energy) which means crustacea, corals and molluscs aren't automatically prey to pH changes in the same way that say a limestone rock would be'
