Based on the figures, the oceans of the world simply will not be able to sustainably produce enough food to feed the world's growing population, especially if overfishing, pollution and various other harmful practices continue unmitigated.

As relayed by Futurity.org, the new study looked at the progress of 10 different public goals for the world's oceans, which include things like the sustainable harvesting of seafood, the effectiveness of coastal protection programs and the general livelihood of coastal economies. Each category was rated on a scale of 0 to 100 using various criteria, and a final score was tabulated for overall ocean health, also known as a Global Index Score.
