Ocean Health Suffers From Overfishing
The health of the world's oceans are inextricably linked to human health and well-being; more than one-third of people worldwide depend on seafood for 20 percent of their animal protein, according to the United Nations.
To gauge how well the oceans are doing, a large team of researchers created a wide-ranging measure of the oceans' health. On Tuesday, the second annual edition of the Ocean Health Index was released, which shows that unsustainable fishing has taken a toll on fish populations around the world, putting many people's food security at risk, said Ben Halpern, a marine biologist at the University of California, Santa Barbara, and the project's lead scientist.
The index ranks the health of the oceans in 10 different categories, including subjects such as purity of water and levels of tourism, on a country-by-country basis. This year the world's oceans scored a 65 out of 100 possible points, unchanged from when it was first released last year, Halpern told LiveScience. While it could be worse, the score suggests there's "definite room for improvement," he said.
