The problem is we're effectively using the public as a guinea pig. Then when lots of issues are detected, the specific chemicals used are banned. Then industry quickly replaces it with a very similar compound(see e.g Bisphenol A being replaced with Bisphenol S and F in "BPA free plastics" even though it's not known that they are safer) which is likely to have similar problems, but not proven to yet, kicking the can down the road.

Some possible regulations come to mind. For instance, maybe a ban or very strict regulations on the widespread use of compounds like PFAS that have no known biological or other natural path of degradation. Because it's become very clear that such compounds are inevitably going to end up spread all over global ecosystems.

Edit: So I did some more research. Not only are BPS and BPF not known to be safer, they are already known to have many of the same problems as BPA. To make things worse BPS and possibly BPF are even less degradable than BPA. So they may even be worse. This is not even a little surprising. Their structure is identical except for the linkage between the phenol groups. From pharmacology it's well known that highly similar structures tend to have similar pharmacodynamic properties. So they're not even remotely likely to have been good replacements before the growing mountain of evidence to the contrary appeared. Clearly this blatantly irresponsible behaviour from industry needs to be stopped.
