I read this and my best guess is that the "scientists" did not know that land vegetation consumes more oxygen when it decays than it ever gave off during life. The reason we have a surplus of oxygen in our atmosphere is the plankton in the water mostly gets covered up and decays anaerobically without consuming oxygen so the oxygen it produced is not used up through decay. This seldom happens with land vegetation. They should have concentrated more on a bigger ocean that was truly alive and functioning in a way that when the plankton died it was removed/covered up it might have worked.
But, ... their ocean seems way to small. weedmic 17:02, Dec 7, 2011 (UTC)
In reply to the above, this website
[1] suggests that the CO2 levels rose significantly due to too much soil in the tropical rainforest section, and I remember reading an article that said the O2 levels also went down because freshly-laid concrete has a tendency to absorb air for up to ten years after it has set, and this threw out the balance (the link above aludes to this but doesn't go into detail). Should there be a section of the article dedicated to the reasons behind the problems and issues that arose in the Bioshpere 2 project?

The real reason for this issue was because of the complete lack of phytoplankton in the water, which produce 80% of the worlds oxygen through photosynthesis. From my viewpoint, that the 'scientists' at the bioshpphere did not know this, and simply relied on trees and other vegetation to do all the photosynthesis, shows a real lack of scientific knowledge. every 'scientist' should know this.

22 photos of the interior of Biosphere 2 in its current state. http://www.odditycentral.com/pics/true-horse-power-vehicle.html Amazingly, some of the plants are still alive, mostly the desert types that can exist with little water. The potential for good science experiments still exists there, if the place could be completely cleaned of all living things, sealed even better then restocked very carefully so unwanted pests like roaches don't get put in. —Preceding unsigned comment added by 66.232.94.33 ( talk) 10:17, 11 April 2010 (UTC)
Would someone add some notes on the Min-A-Max system used to build the structure? There's a very informative article here: http://radio-weblogs.com/0119080/stories/2003/02/04/galleryMinamaxAndOtherSpac.html

I can't believe this author is being allowed to perpetuate so many long-debunked mistruths and to avoid all the very real criticism of this joke of an endeavor. Please read Marc Coopers's 1991 Village Voice article "Take This Terrarium and Shove It" then scrap this entire Wikipedia entry, plus the equally bogus entries for John P. Allen and Ed Bass. I'm aware that more legitimate scientists are now in charge, but that doesn't mean we can accept lies about how it began. 173.228.14.148 ( talk) 04:35, 31 December 2014 (UTC)

barely seem relevant and almost like a dialogue (i.e., "the location suggests it was not legitimate", "actually, yes, it is located in such a location and its really quite great"). I propose removing these parts. 23.91.141.9 ( talk) 23:26, 6 April 2015 (UTC)
This article avoids mentioning some of the other problems in the second (failed) experiment. (It also claims the expt. was 'incomplete' rather than failed. It was, of course, both.) The most egregious problem was that it was NOT closed. Personnel were allowed to enter and leave regularly. And various materials were added over time. 71.29.173.173 ( talk) 20:52, 16 July 2016 (UTC)
