I highly recommend the Neil DeGrasse Tyson Cosmos episode "The Clean Room" [1], which is about the prevalence of lead gasoline saturating our environment so thoroughly with lead that researcher Clair Patterson's research on the age of the Earth was rendered nearly impossible. Patterson made it his mission to get lead out of gasoline for the detrimental cognitive effects it would have on the populace, but corporations fought him (with the same tactics they use to fight climate scientists today) and lead was not phased out of gasoline until the mid-1970s [2]. It's unfortunate, research in recent years has shown a stronger and stronger positive correlation between lead in the environment during childhood and violent crime later in life [3][4][5]. This is why what happened in Flint Michigan is a crime against society. That community is going to suffer the consequences of the lead in their water supply for an entire generation.
