So are we as a society not supposed to take advantage of learning from past mistakes? 100 years ago we flushed raw sewage into rivers and streams. Then we learned that sewage wrecks our water supply and also our health so we started to treat the sewage. I'm struggling to understand your angry and bitter tone.

But that's not the reality we live in.
