Have you seen this Veritasium video about the man who came up with adding tetraethyllead to gasonline and it's negative impact on humanity?

Given how dangerous lead is in even the tiniest quantities it is really surprising that there has not been more pressure to change that.

Don't have time for the video, but if that was Thomas Midgley, he was quite the one-man environmental catastrophe.

It is indeed. The video (which I just happened upon yesterday) does a great job of describing his impact on humanity and it was interesting to learn that prop planes were still allowed to use leaded gasoline--I had no idea. Ironic he died by strangulating himself in one of his own inventions.
