			== Various Problems Encountered ==
			Biosphere suffered from a number of problems. In no particular order:

			--- Oxygen levels dropped quickly from curing concrete and from oxygen breathing bacteria. This made physical labour challenging.

			--- There were insect species which grew out of control. These included ants and cockroaches.

			--- Air conditioning was inadequate. It got very hot inside.

			--- The team split into two factions, those who wished to continue as planned, and those who wanted to bring in materials from outside to make things better. This division grew more acrimonious as time went on and eventually ended the mission early.

			There were a number of planning failures. The concrete had not fully cured, which reduced the oxygen content of the air. Air conditioning was inadequate for a huge greenhouse in the desert which caused over heating.

			Biosphere 2 was in essence a model of a [[Settlement\|martian]] or moon [[settlement]]. The failure of the experiment shows that these types of systems are much more complex than expected.

	It seems that the main original difficulty was underestimating the problem of establishing a stable recycling system of plants and animals in imitation of the wild recycling system on Earth. More regular study of the various animals and plants to be put into such a system is required to learn all of their specific needs and products. Proper research should be done in smaller scale enclosures with regular records being kept. Just how difficult it is produce a closed recycling life support system as originally planned for Biosphere 2 will be learned when the goal is accomplished.
