Hydroponic farming is missing one very important ingredient -- soil -- and a whole way of thinking that goes along with it.
Judy Blackshear's insight:
I am of two minds on this. It has long bothered me that hydroponic farming relies on a lot of synthetic fertilizer to feed the plants, and that aquaponic farming gets only nitrogen (from the fish poop). I wonder where the rest of the nutrition comes from, especially the minerals that come from the soil.
But urban hydroponic/aquaponic farms, both large-scale and small, probably do still play an important role in bringing fresh food closer to the people who need it.
I'm afraid I do not have an informed opinion on this - so I will wait as the scientists and farmers and nutritionists work it out. I would like to see a well-constructed study comparing the nutrition of aquaponically-grown foods with organically (in soil) grown.
We live in an era of accelerating change, when scientific and technological advancements are arriving rapidly. As a result, we are developing a new language to describe our civilization as it evolves. Here are 20 terms and concepts that you'll need to navigate our future.

Doesn't really fit anywhere, but I wanted to keep this somewhere so I could look it over later. My first glance revealed some interesting concepts.
