The team claimed the only new supplies brought in were plastic bags, but others accused them of bringing food and other items. More criticism was raised when it was learned that, likewise, the project injected oxygen in January 1993 to make up for a failure in the balance of the system that resulted in the amount of oxygen steadily declining.</span><sup id="gmail-cite_ref-56" class="gmail-reference" style="line-height:1;unicode-bidi:isolate;font-size:11.2px;color:rgb(32,33,34);font-family:sans-serif"><a href="https://en.wikipedia.org/wiki/Biosphere_2#cite_note-56" style="text-decoration-line:none;color:rgb(51,102,204);background:none">[56]</a></sup><span style="color:rgb(32,33,34);font-family:sans-serif;font-size:14px"> Some thought that these criticisms ignored that Biosphere 2 was an experiment where the unexpected would occur, adding to knowledge of how complex ecologies develop and interact, not a demonstration where everything was known in advance.</span><sup id="gmail-cite_ref-57" class="gmail-reference" style="line-height:1;unicode-bidi:isolate;font-size:11.2px;color:rgb(32,33,34);font-family:sans-serif"><a href="https://en.wikipedia.org/wiki/Biosphere_2#cite_note-57" style="text-decoration-line:none;color:rgb(51,102,204);background:none">[57]</a></sup><span style="color:rgb(32,33,34);font-family:sans-serif;font-size:14px"> </span><a href="https://en.wikipedia.org/wiki/Howard_T._Odum" title="Howard T.
