It’s no secret that the health of our oceans is under extreme threat.
With dangers like overfishing, climate change and ocean acidification, keeping our oceans healthy is a complex problem that has proved difficult to address.
Scientists and policymakers now have a little help, however, with the recent creation of the Ocean Health Index. Developed by a multidisciplinary team of researchers, the index provides an overall score for global ocean health, using 10 different social, economic and ecological criteria such as water quality, habitat, livelihoods, and coastal protection.
The research findings, published in the journal Nature last week, gave our oceans a collective score of 60 out of a possible 100 points. Scores were calculated for 133 different regions located around the world, with marine waters from some countries ranking as low as 36 while others as high as 86. The United States scored only a little higher than the global average, with 63 points. Disturbingly, only 5 percent of these regions scored above 70 points.
