Aquaponics

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.
