Mars city question

Sad The Biosphere projects failed for many different reasons, including the build-up of toxins, for example.

Certainly the creation of a truly closed, self-sustaining biosphere ala the Biosphere 2 attempt some years back is beyond our current or (most likely) near term abilities. But getting a Mars base to the point where it can grow its own food (at least in principle), source its water from the planet, and produce its own air should be doable with tech that is less advanced than what a full on 'Biosphere Mars' would require. Also producing its own rocket fuel/reaction mass is something that Zubrin has discussed a good bit IIRC.

Working to minimize (or even eventually eliminate) the need for shipments from Earth seems like a worthwhile goal. Along with developing tech to reduce the cost and travel time of getting to/from the planets.
