Came across this a while ago, thought it may be of interest to some.

Industrial scale aquaponics.

Very, very possible. Maybe Geoff Wilsons roof top aquaponics is a likelyhood somewhere down the road.
It really makes you wonder just where the food will come from if population keeps expanding the way it is.
I don't think we will ever reach that kind of population anyway, mankind has a happy knack of getting into a fight or two and knocking a few million of each other over every few decades. Some of the mad hatters we have as leaders around the world at the moment are very capable of hitting the red nuke button in a fit of megalomania.

Incredible that however much has been learnt in the past and by that I mean wars and agriculture it seems as if everyone has to 'reinvent the wheel' over and over again. There will always be wars based on religion(s) and hasn't man been trying for years to get water to the desert in order to grow crops?
