I was reading in the news that air pollution is damaging our lungs more than they thought because the safe levels were based on American research that has different amounts of small particles than European traffic makes.
The latest research was telling them that the smaller particles were causing more damage as they go further into the lung and do not show up at the safe levels that we have now. The research done in Holland is what Europe will have to change the safe levels for everyones lungs sake.
I know from my own experience city traffic makes me fell awful and now I have begun to understand why with air pollution the elephant in the room damaging more lungs without a public outcry.
