Stop eating any kind of factory-processed or packaged food (with plastic packaging, canned packaging, etc, as these are coated), stop using any clothing/shoes/furniture not based on natural fibers or with water-resistant or stain-resistant properties, using any sort of coated cookware (return to cast iron), etc and that still won't do anything about commercial or industrial uses of those chemicals that contaminate your water supply/etc. Like firefighting foam, for example. The Air Force is going to keep using it regardless of what you do personally, despite them having less toxic alternatives available. simply banning it directly wouldn't help, companies will just move on to the next thing, legally it will be presumed to be safe until there is science to prove that it's not, and we will need another 75 years of epidemiological studies to build that proof. Rinse and repeat forever. The long term answer is that we need to reverse the legal model and have companies prove that any chemical they intend to introduce is safe, rather than the public having to (first learn what proprietary chemicals are being used, as this is not legally required to be disclosed, and then) prove that it's dangerous, but that won't happen under any conservative or liberal governments in the US, it will take a leftist government pushing heavy environmental regulations before there's any chance of phasing this sort of thing out. Until then, it's on to the next poison.
