ONE OF MANY THINGS I DON’T UNDERSTAND

It’s kind of interesting.  A man who was part of President Obama’s EPA was interviewed on TV this evening.  He said Trump’s reversal of some of Obama’s environmental actions will make no difference because the coal industry is dead and is not going to make a comeback.  Then he decried Trump’s actions, saying they will threaten our environment.  What I don’t understand is this – if coal is not coming back i.e. nothing is going to change, how can the environment be negatively impacted? It’s a puzzlement.
