Carol responds:

I can't answer the main question, but I can tell you what a biosphere
(bio = life = sphere) is. Biosphere 1 is the earth itself. Biosphere 2
is an enclosed, self-sustaining ecosystem twenty miles down Oracle
Road from my apartment. Here's a link:

Carol, who doubts that a person living in an apartment could create
her own biosphere!
