Our oceans simply cannot yield sufficient quantities of fresh fish and seafood to produce enough viable protein for the Earth's population.

That poses a dilemna for Fishermen, however, for a large majority of the world, without underwater agriculture, they would simply go hungry...or die.

I wonder what can be done to speed up the Aquaculture then, since it is vital to so many people? What are the world's governments doing to contribute to safe, clean aquaculture to feed our people? If nothing...why NOT?
