Destroy the fish，and you destroy the fishermen's means of living．At least 60 [24] of the world's commercially important fish [25] are already over-fished，or fished to the limit．As a result, governments have had to close down some areas of sea to commercial fishing．
Big，high-tech fleets [26] that everything in their path is pulled out of water．Anything too small, or the wrong thing，is thrown back either dead or dying．That's an [27] of more than 20 million metric tons every year．
[28] .
