I think that's a question for the ecologists.
My guess, though, would be that part of the concern is people visiting the site on an ongoing basis as a tourist location, which won't happen with a buried power line.

Now ask the ecologists if bulldozing and paving over hundreds of square miles of forest to make a city is ecologically sound. You might be shocked to learn that your entire so-called "civilization" is a pox on the planet.
