I am also interested in strip mining and "Mountain Top Removal" problems as this link describes:

"It's the dirty little secret that the U.S. government wants to keep hidden from the eyes of America, and the world. There is no better example of a human catastrophe linked to environmental destruction than life in the coal fields of Appalachia."

Well, HO once told me (personal communiction) that mountain top removal modified the environment in not necessarily a "bad" way. Needless to say, I disagreed and still do. It was the pollution stuff created after the mining that bothered me most--aside from screwing around with the Appalachians as if we humans were "God". On the other hand, most environments we live in on Earth are human modified now. What is actually "natural" is more and more scarce. And as climate science tells us, we have modified the Earth's atmosphere and oceans irrevocably--at least in any timeframe we care about.

Sorry, HO, had to speak to it.
Grin:
   Hmmm, I can see that this coal set may well extend for more than the originally planned couple of weekends.  Now I also have to go and find some photographs.
Yeah - it was at dinner in Denver.  I remember his impish grin as defended how Appalachia was much better for getting rid of all those pesky mountains and giving them lots of nice flat useable land.
