A new report by Oceana shows just how connected our oceans are to human well-being, and how even small changes in the ocean’s pH levels, coupled with climate change, can have profound consequences for security. According to the report, by the middle of this century climate change and ocean acidification may dramatically heighten food insecurity among nations and territories that are heavily dependent on the oceans for sustenance. The report gauges a country’s likely “vulnerability to food security threats from climate change and ocean acidification” by assessing the exposure of its fisheries to climate change and ocean acidification, its dependence on fisheries as a source of sustenance for its population, and its adaptive capacity.
