Highly regional really.Our soil is depleted, our water is compromised with pesticides, herbicides and pharmaceuticals. Our air is clean fortunately, thanks to de-industrialization. You go to buy leafy vegetables and they have never seen sunlight in the hydroponic existence while everything else has been harvested unripe and ripened in a warehouse.
Prognosis negative...
That said I believe almost nothing from any entity selling/telling me something - with the premise it is safe to ingest any substance. I mean they may even not be lying at the time. It's just at the that point in time maybe no one knows. From that level it just goes downhill to some very inefficient protector even being in on it. I hardly trust "organic" labeling. I kinda trust the local person at the farmers market telling me they don't spray, with anything.
My mind and body were duped by the food pyramid.
