Ocean acidification poses a very serious threat to the maintenance of species that rely on saturated calcium carbonate minerals to form their shells or skeletons. It will greatly impact molusc populations, for instance, and indirectly damage the coral reefs and arctic ecosystems. But the socio-economic consequences for humans will vary locally whereas carbon release is a non point-source phenomenon, and the link between this problem and our food chain is still poorly understood. Still, we know that the fight against acidification is a priority and it certainly involves economic interests. Under such circumstances, how can we mobilize stakeholders through economic incentives to increase the impact of countermeasures?
