What was the real issue here?
This was an interesting film, and quite educational. I believe that Robert Bilott was acting with good intentions, attempting to inform the public of what goes on in the shadows with corporations that furnish our lives, figuratively and literally.
After watching this film, I think it's important to understand the issue here (arguably) is not with the end-product of Teflon. Teflon is a brand of products that is created with PTFE (polytetrafluoroethylene). PTFE is essentially a plastic, and it's ubiquitous in everyday life, for better or worse (think bottled water).
PFOA or C8, as shown in the film, is the chemical and precursor used in the production of these products. By and large, these products have been demonstrated to be safe. The area of concern starts to apply when Teflon pans or bottled-water is warmed up to a certain temperature, allowing the fumes to be absorbed into the lungs. This is difficult to do, as the temperature has to be around 622F for the pan to begin degrading and releasing the fumes. When this does happen, fume fever can occur, assuming you breathe in large enough quantities, which is unlikely from only one pan.
And so what is the real issue here? The issue is around the safety of the production of these products. DuPont concealed the dangers around the production of its brand products, namely with the use of PFOA and the implications of leaking it into the water supply.
As usual, there will be a portion of people who watch this film, don't look beyond the surface level, and induce themselves into a fueled paranoia thinking everything and everyone is out to get them. I'm not saying the food we eat isn't bad for us or the air we breathe is optimal. Yes, the world is an unscrupulous and dangerous place. Yes, we live in a state of unbridled capitalism, where greed runs rampant and power corrupts.
It is impossible to make the world 100% fool-proof. In today's world, our living conditions are predicated on the production of the everyday items (sustenance, shelter, entertainment, transportation) corporations furnish us with.
Are they 100% safe? No, of course not. Nothing is 100% safe.
