A large part of the carbon dioxide (CO2) emissions released by human activities is absorbed by the oceans, just like other natural carbon reservoirs such as forests, which are referred to as “carbon sinks”. « . This CO2 retention capacity plays a fundamental role in climate regulation. The very significant increase in CO2 of anthropogenic origin results in the acidification of the oceans and is at the origin of a very significant loss of marine biodiversity due to the degradation of coral reefs.
