Like everyone else, I am looking into ways of providing healthier food for my family. To this end, I've been considering auqaponics, but I am concerned about the toxic chemicals from the various petroleum products required for this (pond liners, plastic tanks, PVC piping and glue). I was hoping we could talk about ranking the different sources. Maybe auqaponics isn't perfect, but better than some alternatives? Or maybe it should be avoided all together, and other methods should be looked at.
Here is a quick list to rank, and add any other sources I have forgotten.
typical supermarket fair
home garden (best? not feasable 8 months of the year in my area)
Long time listern
