I'd say the chemical companies care more for corporate profits than they care about human life ... they have a pretty good idea what this chemical does, and they have been using it more and more as the years go on.
I think you make a broad and incorrect assumption here. Like it or not, our society is full of chemicals. We cannot enjoy the quality of life we have today without chemicals. And guess what. Every single chemical and artificial material we use has some sort of health impact. Should we turn our back on technology and go back to the stone age just to avoid it? You seem to preach on and on about how chemical companies and our government are evil and care nothing about human life. I call BS. You just have a narrow focused agenda and are unwilling/incapable of seeing the bigger picture.
If you want to hide from everything in the world that can harm you, fine. You can try it. But it ain't possible. Heck, a lot of the plants God put on this earth are dangerous too. You gonna sue him too? He didn't provide a warning label either. If you eat a poisonous plant, does make Him criminally negligible? If you spend time under the sun that He hung in the sky and get skin cancer, do you think you have a case?
