For the first time in history, humans are poised to harvest more fish and seafood from farms than they catch in the wild.
This milestone, expected within two years, would help keep the oceans from being overfished except for one issue: Those farmed fish eat wild fish.

They are attracting funding from major investors like BP PLC and Temasek, Singapore’s national investment vehicle.
