Didn&#x27;t you just warn me about comparing countryside to cities in China?  In any case, the high levels in Kentucky are the legacy of coal country, which China would be wise to avoid.  It also doesn&#x27;t help that China&#x27;s rate is <i>increasing</i> year-over-year along with their population that&#x27;s already 5x the entire state of Kentucky. I literally can&#x27;t fathom why you&#x27;re trying to minimize the impact of dirty air in Beijing.
