Tell you what..go get a paper or plastic bag, fill it with coal smoke, and take a big huff..then pass it around to your kids and grandkids..
Analysis of lung disease, greenhouse gas, acid rain, and NOx emissions has been accepted science for over 40 years.  
Coal is too expensive to burn not because of tax, but because of limits on carbon emissions. Homo sapiens require oxygen to live, like it or not.
