Have they ever used that technique in the UK? I don't think the UK has mountains suitable for mountaintop removal - they are famous for their underground operations.

I've always filed mountaintop removal mining as one of those "weird things Americans do" approaches. Probably associated with unusual geology or something.

I think the UK had the none-mountainous version of strip mining - open pit mines. I think there aren't any in operation currently, and I'm unsure if they were for coal or just other commodities.

Even if not, the collieries in Wales, built on top of coal shafts, were quite industrial-looking/landscape-runining. https://museum.wales/articles/1260/Nantgarw-Colliery---once-...

We used the technique until we ran out of mountains, hence current lack of mountains.

Haha, I'm sorry but it's hilarious that you guys are arguing with the person who had firsthand knowledge. It's ironic, really. You're talking about strip mining. There are other types of mines (drift, slope, shaft, etc).

and all of them are horrendously bad for the environment, the end.

As are the wind turbines with there non-recyclable blades and bird kills.
