Huh? We stopped using lead in petrol about 40 years ago. You do have to make a tradeoff between keeping the economy going and unknown risks. We continued to use concrete despite early fears about the danger of cement dust. We still use social media despite fears about psychological problems. We still drive cars despite the high danger of death. Nothing's perfectly safe. We even still have babies knowing that all of them will die, and worse males will probably die sooner than females. Abort male foetuses for their own safety? You have to draw a line somewhere.
