We’re now farming more fish than cattle... wtf???

"China, which accounts for 62% of the world’s aquaculture, raises fish like silver carp, which can survive on cheaper inputs like grass and plankton. But farmed shrimp and salmon survive on fishmeal and fish oil from anchovies, sardines, and herring, which are greatly over-harvested from the seas. Our rising consumption of fish can’t continue, then, unless we find more sustainable ways to farm them.
