The threat eating away at museum treasures

Idea: For long-term storage & preservation of rare "treasures" (whether they be museums pieces, library books, national archive documents, or whoever), invest in oxygen-depleted facilities. At low-enough O2, nothing aerobic - be it bacteria, mold, bug, rodent, or whatever - can grow. Most can't even live. Gradual oxidation damage (paper turning yellow then brown, etc.) ceases. And disastrous fires can't happen.
