Food
Life support systems could include a plant cultivation system which allows food to be grown within buildings and/or vessels. However, no such system has flown in space as yet. Such a system could be designed so that it reuses most (otherwise lost) nutrients. This is done, for example, by composting toilets which reintegrate waste material (excrement) back into the system, allowing the nutrients to be taken up by the food crops. The food coming from the crops is then consumed again by the system's users and the cycle continues.

Famous quotes containing the word food:
“This is the only “wet” community in a wide area, and is the rendezvous of cow hands seeking to break the monotony of chuck wagon food and range life. Friday night is the “big time” for local cowboys, and consequently the calaboose is called the “Friday night jail.””
—Administration in the State of Texa, U.S. public relief program (1935-1943)
“There is such a thing as food and such a thing as poison. But the damage done by those who pass off poison as food is far less than that done by those who generation after generation convince people that food is poison.”
—Paul Goodman (1911–1972)
“It is the mark of a mean, vulgar and ignoble spirit to dwell on the thought of food before meal times or worse to dwell on it afterwards, to discuss it and wallow in the remembered pleasures of every mouthful. Those whose minds dwell before dinner on the spit, and after on the dishes, are fit only to be scullions.”
—Francis De Sales, Saint (1567–1622)
