Study: Just 13% of ocean can be considered wilderness, and less than 5% of it in PAs
Humans have wiped out most of the pristine parts of the world’s oceans, a new study has found.
In the first global mapping of human impacts on marine environments, a team of scientists from Australia, Canada and the United States demonstrated that few corners of the globe have been left untouched by shipping, mining and commercial fishing. Just 13 percent of the world’s oceans hold intact ecosystems and are free of these impacts — the team’s definition of marine wilderness. And of the remaining underwater wilderness, less than 5 percent is protected.
