They probably haven't thought through all the good chemicals have done. If we stopped all progress in chemicals 100 years ago our world would like a very different place.
A less wealthy place where more people died of starvation.
Great, so we're just going to need a few long term clinical trials assessing the impacts of each of ingestion, skin contact, inhalation, eye exposure, etc. separately for childhood exposure, adult exposure, exposure during pregnancy, acute exposure, chronic exposure, and so on. 100 billion dollars and thirty years later, maybe you can start provisionally selling your slightly better scotch tape.
That’s a little disingenuous. Something like an herbicide that’s broadly applied to fruits and vegetables that millions of people are eating should be under far higher scrutiny than a niche product that has limited human contact.
Things that don't have much human contact in the general population can have significant human contact during the manufacturing process of products containing or processed with them.
