What if the solution begins with science?
Leaded gasoline was known to be problematic from day 1. The science was suppressed for years. Look up what happened immediately after that iconic tv stunt where the guy washed his hands in leaded gasoline (he had a psychotic break from lead exposure and was institutionalized)
Forever chemicals were known to be problematic and far more prevent than expected. 3M suppressed the science for literally decades. Senior leadership at 3M deliberately suppressed the data.
We should crush without mercy those who rob us of the right to protect ourselves when they suppress the science that is supposed to provide warning. Make penalties for suppressing science so severe that nobody attempts to do it. How specifically? If you hide information that your product kills, you get prosecuted for murder. If there are financial damages make them treble damages. Make it hurt so bad it’s not worth doing.
The answer is knowing. Individuals and institutions knowing the real dangers and acting appropriately. The place of governance is punishing those who knowingly hide the dangers and prevent us from taking appropriate proactive action.
