Kevin Drums research about a strong correlation between lead and crime seems to impact the Caribbean as well:
“When I read The New York Times writing about a 40 percent fall in Jamaica’s murder rate (it’s still very high) I naturally wondered about Kevin Drum’s lead angle. And he says it fits the pattern: From 1990 to 2000, Jamaica started phasing out leaded gasoline. From 2009 to 2013, the crime rate has fallen forty percent. In other words, Jamaica is likely starting to see the beneficial impact of a youth cohort with lower levels of lead poisoning. And just based on the lead channel alone you’d expect to see meaningful further improvements over the next 5-10 years as the kids who were born after the complete eradication of leaded gasoline grow up.”

If this is true, lead removal should become the number one priority of governments worldwide, and communities across the US.
Additionally, it goes to show you the impact that being pollution free has. We could have avoided a lot of this. And what other heavy metals in the air are affecting society right now?
