@KoiwiGal - I'm of two minds about that. I don't think it's the kind of thing that you can really ever put in black and white terms. Because I think that conservation should really matter, but in some cases the best way forward is by using new technology. I'd much rather that we have the most sustainable architecture in place to conserve energy and water, rather than keeping old designs around because they look nice.
The ideal solution is a compromise between the two, but if it comes to a conflict between conserving the traditional and attempting to make the future better, I would rather ensure the future of a city.
