Well, geewhiz.  First time I've ever heard of this practice.  May be in
over my head on a newsgroup primarilly for botanists and biologists
(i'm neither), but have always thought that plants used mostly carbon
dioxide from the air and left the air higher (as a percentage of the
total) in oxygen.  Am I all wet here??  Chuck

I have known the time they removed flowers from patient rooms in Belgian
hospitals for the reason of "taking away oxygen". But things seem to have
changed know: most people know that's the amount of oxygen taken away by
the plants is neglectible, compared with what the patients themselves use
by breathing. Nevertheless I still hear from time to time from people the
undestroyable misbelief that it's necessary to take plant away from
sleeping rooms.
