Hold up there on recommending making oil out of the plants that have drawn contaminates out of the soil....and you know (as an afterthought of reading some information) you may have just solved why the bees are dying off. Those plants are now full of the contamination they withdrew from the soil and they therefore have to be disposed of in a similar manner as the actual contaminated soil. This would be particularly concerning in heavily contaminated nuclear sites like Fukushima and Chernobyl, those plants would have to be handled as radioactive material. Fukushima has not used hemp but of all things sunflowers....hence: how to they keep bees and birds away from such highly toxic plants?...what is the effect this is having on bees and birds?....maybe that's something they need to look into as I think I've read before there is a greater concern abroad as they've lost more bees then we have. Chernobyl has been using hemp but it has to be cultivated and destroyed just the same as the native plants on the property has because it's system is infiltrated with contaminated waste. I've heard they suspect it could be all these cell towers causing the decline in bees but what if it's some freak genetic mutation from radioactive plants?

Anyway...don't smoke, bake or shake any plants used to removed contaminates from the soil, unless of course your into heavy metals...and I am not talking music. lol.
