want to know why a large portion of the us doesn't trust big ag or government findings?
There are 60,000 unregulated chemicals in use by chemical companies right now and the EPA/FDA/USDA aren't regulating. This is a frightening David-vs-Goliath New York Times piece which is well worth the read. Here are a couple snippets:
Bilott learned from the documents that 3M and DuPont had been conducting secret medical studies on PFOA for more than four decades. In 1961, DuPont researchers found that the chemical could increase the size of the liver in rats and rabbits. A year later, they replicated these results in studies with dogs. PFOA’s peculiar chemical structure made it uncannily resistant to degradation. It also bound to plasma proteins in the blood, circulating through each organ in the body. In the 1970s, DuPont discovered that there were high concentrations of PFOA in the blood of factory workers at Washington Works. They did not tell their workers this. In 1981, 3M — which continued to serve as the supplier of PFOA to DuPont and other corporations — found that ingestion of the substance caused birth defects in rats. After 3M shared this information, DuPont tested the children of pregnant employees in their Teflon division. Of seven births, two had eye defects. DuPont did not make this information public...
...But Bilott faced a vexing legal problem. PFOA was not a regulated substance. It appeared on no federal or state list of contaminants. How could Bilott claim that 70,000 people had been poisoned if the government didn’t recognize PFOA as a toxin — if PFOA, legally speaking, was no different than water itself?
