This is fantastic. Why aren't we all doing this?

As most of you know, I am a California gal that moved to New York. I live in Manhattan and then Brooklyn, so you may see what I am beyond excited about this taking off. Not only do I think this system is way cool, but I think that it could also be used all over the world where soil is uncultivatable
"Aquaponics is a method of combined fish and vegetable farming that requires no soil," explains Roman Gaus from The Atlantic Cities
about the process. "The farmer cultivates freshwater fish (aquaculture)
and plants (hydroponics) in a recirculating water system that exchanges
nutrients between the two. Wastewater from the fish serves as organic
fertilizer for the plants, while the plants clean the water of fish
feces and urine."
Growing organic food in almost anywhere.
Because
aquaponics is essentially a closed system, with the exception of fish
food having to be cultivated or purchased separately, it can function
independently, and without many of the normal inputs required for
traditional farming. This means that a well-designed
aquaponics
system can be installed and operated virtually anywhere, including in
dense urban environments -- high-rise rooftops, the tops of parking
structures, and even basic parking lots are just a few examples of the
many locations where high-output aquaponics systems can work.
