I personally think that it's OK to view human development as separate from nature. I don't really care if the land within city limits is polluted or overexploited, so long as it's just the that city and the area outside of it is well preserved, and the city doesn't sprawl out like they do in the USA (suburbs...). Ultra dense city centers like Hong Kong are far more preferable to preserving the environment to sparse, but enormous settlements like Los Angeles, which are far more wasteful and harmful to the environment per-capita. While I agree it would be nice to have greener cities as a resident of a major city (Tokyo), it's not a requirement for a high quality of urban life, nor is it a requirement for preserving the environment.
