We have tossed a lot of chemicals into the environment without really understanding what they might do. I’m not sure how we could have done it differently. Some effects don’t show up until you have mass exposure. The best we can do is ban things once we discover there is a problem. The problem then becomes you have entrenched interests manufacturing those chemicals, which makes them hard to ban. Somewhere back in common law we made the mistake of allowing private parties to pollute the commons. And now we have centuries of case law that are impossible to overturn.
