Biosphere 2 is described in this Wiki article. It is, as far as I know, the first experiment to determine whether human beings could live in a closed system, dependent on plant life converting carbon dioxide into oxygen. The experiment was effectively terminated when the oxygen levels failed to reach those calculated, and the participants began to suffer the ill-effects of oxygen starvation. One theory for the failure was that the oxygen demand of the curing concrete using extensively in the new construction was not taken into account.
This should not be a factor when TV's favourite geologist, Iain Stewart, steps into a container at the Eden Project, as reported by the Indy.

Important experiment, especially if we are to colonise other worlds.
