International ecologists and economists believe "the world will run out of seafood by 2048" if current fishing rates continue.

 

A journal Science study "conclude(d) that overfishing, pollution and other environmental factors are wiping out important species" globally. They're also impeding world oceans' ability to produce seafood, filter nutrients, and resist disease.

Marine biologist Boris Worm warned:

"We really see the end of the line now. It's within our lifetime. Our children will see a world without seafood if we don't change things."

Researchers studied fish populations, catch records, and ocean ecosystems for four years. By 2003, 29% of all species collapsed. It means they're at least "90% below their historic maximum catch levels."
