Overfishing is threatening food security for hundreds of millions of people and destroying ocean ecosystems worldwide. In fact, the fishing industry can’t even sell everything it catches.

Just 1.6% of the world's oceans have been declared marine protected areas (MPAs) and fishing is allowed in 90% of them.
