You may not be concerned with water, but globally we all should be. You may have cracked the code on a SHTF scenario for you. But in just the big picture, hydroponics (organic) and aquaponics (organic by default) will be huge pieces to the sustainable agriculture model. If you are in Southern California or Arizona, all of sudden the economics look allot better. Look at the yields produced per square foot in a greenhouse and the shrinking availability of arable land, plus the rising population... Well you see where this is going. Greenhouse food production is the future. Aquaponics can have the greatest impact in poor urban communities. Hydroponics may be a bit easier and actually have a higher ROI. That being said, aquaponics is not snake oil and it indeed has its place. Especially if you are concerned about mercury or radiation riddled fish. I'm not selling anything thing.
