So yes to that extent I think that it is a load of crap. HOWEVER that doesn’t mean that I don’t believe we should be doing everything we can to clean up the planet we live on so we have clean water to drink, clean air to breathe and live a non-wasteful lifestyle that our planet can sustain. Vehicle emissions cause a large part in that. Violent crime in the UK and other first world nations is a lot lower than it was 25 years ago because we removed lead, which is a nerve toxin, from paint and importantly, petrol so we were no longer giving ourselves lead poisoning.
^^^^^^^^^^^^^
ok,il bite basically becaise im driving here and cant be bothered waiting on google to tell me…
what has removing lead from paint got to do with violent crime or the lack of it in the uk?
im sure theres several others pondering this dilemma so itl save them a sleepless night if you just spill the beans before you start your trunk.

And I think that has been cited over 200 times in peer reviewed papers.
Or if you prefer there are articles in
The Express
The Independent
BBC
Guardian
Telegraph
Times
Is it a proven cause and effect? No. Difficult to do that without finding groups of people to be guinea pigs.
EDIT, sorry I messed up the quotes, but I hope it`s still clear.
