HYDROPONICS GOES MAINSTREAM

I first heard about hydroponics in the late 90's, when teachers I worked with at a couple of local schools told me it was an interesting way to get kids interested in science and make a few bucks as well. As the world urbanizes, farmland shrinks, water resources become precious, and people try to reduce the distances food needs to travel from soil to stomach, the motivation is there to do this at a much more sophisticated level, or so reports CNN: "Agriculture Goes Urban and High-Tech." If this really takes off, the whole urban-rural thing could get really interesting.
