Starting in June 2012, the Rockefeller Foundation began investigating the pressing problem of the declining health of the oceans due to climate change, overfishing, pollution and habitat destruction, and the effects of this decline on poor and vulnerable people who depend on marine ecosystems for food and livelihoods. The goal was to better understand the nature of the problem and the potential impact of interventions in the fields of fisheries, aquaculture, poverty, and food security.
