Happens naturally too. The lake appears and drowns some of previously dry land? Ditto. Different species now populate the waters in that area? Ditto.

>Strip mining and tankers burning the worst sludge from refineries are polluting far more, but you don't hear much about that.

...yes and Trump wants those coal jobs back! (and actually thinks they're coming back) If he had his way every mountain in the national parks would have the tops strip mined off. But yes all of these things are bad, strip mining, takers burning, refineries, etc. Of course the direction to go is towards renewable energy but sadly we have the elected the wrong people in the USA at the moment and they refuse to accept this.
