Last month, the New York Times reported on the identification of the largest cluster of advanced black lung 
cases ever reported. (And lest you think that this is fake news, the Times contains a link to the article, which was a Research Letter published by the Journal of the American Medical Association, that known collection of left-wing zealots.) Here’s the sobering summary from one of the authors:
There’s an unacceptably large number of younger miners who have end-stage disease and the only choice is to get a lung transplant or wait it out and die.
Apparently, the increase stems from changes in mining operations that have led to increased exposures to Silica dust. We’ll see if this study has any impact on the Trump administration’s review of the 2014 coal dust rule promulgated by the Obama Administration.
It may be necessary to destroy all the miners in order to save coal mining.
