Air pollution has always affected health.The only reason it is mentioned more and more because it is out of hand.As usual politicians are making decisions after the event.Our streets and towns are clogged up with cars ,no adequate public transport.The irony is that so many busses spew out poison and are poorly maintained in the U.K We are way out beyond the curve.Many towns and city's are taking drastic measures.Never mind we will catch up eventually after many more children deaths.
