It's a good discussion to be having today as hopefully The Lake District is about to be given World Heritage status.
Incidentally, one sentence in the Bath article stood out for me: "Enthusiasts for the scheme attack those who would keep Bath as "a city in aspic"". Aspic's impossible of course, but I don't like people who are trying to make hundreds of millions of pounds out of developments being contemptuous of conservation, as if it's somehow a bad thing.
