Just the mining of coal is polluting the environment - especially air and water. Mountaintop mining is an atrocity.
Yes we know. You want them to lose their jobs and live off the government. It's not shocking they didn't support that
The coal miners are all for living off the gummit. Trump explicitly or implicitly said he'd continue handouts. That's the issue.
As to coal v. natl gas, it's not a black white issue. Even before Obama coal's outlook was not so hot because natl gas was CLEANER, so when gas prices came down, it's hardly surprising that energy companies don't want to invest in coal, with it's higher costs for complying with even W regulations. And breathing is good.
However, Obama increased regulations to combat global warming. And THAT caused many coal energy plants to close, because bringing them into compliance was not cost effective. So, while the plants would probably have closed anyway due to obsolescence, they closed sooner than they might have.
