The Guardian's George Monbiot:
At first it seemed preposterous. The hypothesis was so exotic that I laughed. The rise and fall of violent crime during the second half of the 20th century and first years of the 21st were caused, it proposed, not by changes in policing or imprisonment, single parenthood, recession, crack cocaine or the legalisation of abortion, but mainly by … lead.... It's ridiculous – until you see the evidence.
He's talking about the recent cover story for
Mother Jones, "
America's Real Criminal Element: Lead," by Kevin Drum. The whole article is worth reading, but here are the highlights:
-Lead was added to gasoline in the 1920s to eliminate knocking and pinging in automobile engines.
-Following WWII, the boom in automobile sales resulted in increasing environmental lead levels from auto emissions, particularly in dense population areas.
-Children in these areas were exposed to increasing levels of lead.
-The rise and fall of environmental lead mirrors the rise and fall of violent crime 20 years later.
-The link between lead and crime holds true in different cities, states, and countries.
-Lead is now known to cause damage to the developing brains of children, particularly in areas involved in control of aggression, attention, emotional control, etc. It also lowers IQ. These effects can be seen at blood levels previously thought to be safe.
-In children followed from birth to adulthood, higher blood levels are associated with arrests for violent crime.
-Residual lead in soil and old paint (especially dust produced) continue to cause damage.
-Areas with the highest levels of residual lead also tend to be the areas of highest crime.
When you put the whole puzzle together you get a compelling picture. Drum:
Needless to say, not every child exposed to lead is destined for a life of crime. Everyone over the age of 40 was probably exposed to too much lead during childhood, and most of us suffered nothing more than a few points of IQ loss. But there were plenty of kids already on the margin, and millions of those kids were pushed over the edge from being merely slow or disruptive to becoming part of a nationwide epidemic of violent crime. Once you understand that, it all becomes blindingly obvious. Of course massive lead exposure among children of the postwar era led to larger numbers of violent criminals in the '60s and beyond. And of course when that lead was removed in the '70s and '80s, the children of that generation lost those artificially heightened violent tendencies.
In a follow-up
blog post, Drum is clear that lead was, and is not, the sole driver of crime. Without lead there would continue to be violent crime for a variety of reasons. However the evidence suggests that lead is largely responsible for the epidemic of crime.
Okay, so we have taken lead out of gasoline and paint. Existing environmental lead is still a problem, but at least it's not getting worse. Right? Back to
Monbiot:
There is only one remaining manufacturer of tetraethyl lead on earth. It's based in Ellesmere Port in Britain, and it's called Innospec. The product has long been banned from general sale in the UK, but the company admits on its website that it's still selling this poison to other countries. Innospec refuses to talk to me, but other reports claim that tetraethyl lead is being exported to Afghanistan, Algeria, Burma, Iraq, North Korea, Sierra Leone and Yemen, countries afflicted either by chaos or by governments who don't give a damn about their people.
In 2010 the company admitted that, under the name Associated Octel, it had paid millions of dollars in bribes to officials in Iraq and Indonesia to be allowed to continue, at immense profit, selling tetratethyl lead. Through an agreement with the British and American courts, Innospec was let off so lightly that Lord Justice Thomas complained that "no such arrangement should be made again". God knows how many lives this firm has ruined.
Is it just me, or does it seem like those countries don't need a lower violence threshold?
Back to Drum:
Not only would solving our lead problem do more than any prison to reduce our crime problem, it would produce smarter, better-adjusted kids in the bargain. There's nothing partisan about this, nothing that should appeal more to one group than another. It's just common sense. Cleaning up the rest of the lead that remains in our environment could turn out to be the cheapest, most effective crime prevention tool we have. And we could start doing it tomorrow.
I find the whole idea striking! To think that so much hand-wringing about the cause of crime has perhaps been entirely beside the point--it makes me wonder what other of our ills have been entirely misdiagnosed. It's also another example where industrial production of a product has real consequences for society. What makes this one especially interesting is that it affects behavior.
