Indeed all those fire pits have Injured many..I see a strong disincentive to ever deal with the toxic chemical aspect of our health issue (and others as well).
Like see the Gulf War syndrome where clearly they had known immune disruptors and known toxins and known exposures and its over thirty years later. They still poison the troops.
Pesticides. The 50,000 extra chemicals allegedly put into the environment 1980. Radiation from phones. Poisonous pharmaceuticals etc etc.
It's truly amazing we're still here as a species!.
Imagine the insurance company pay outs, the law suits against the system that would ge needed to clean tgis system up. Too many vested interests.
