i do feel very bad for the people that grew up poor here and like you say, don't have the means to simply move somewhere else. I don't think they really know what the long-term effects of this actually is but there are other places in the world where the AQI is always bad and i suppose Chiang Mai could be a case study in where the air quality is really bad for 6 weeks but otherwise is pretty good.

Unfortunately we won't really know the results of that until it is already too late.
