starship-design: Re:Food in space

[thing@xtra.co.nz]

Everyone seems to be focusing on the finanial aspect of food and 
only at the consumption of the final product. The benifits of growing 
produce in space environments would be high, surely. The 
production and cleaning of air would rank up there. 

It is my belief that the proposed manned Mars mission is planned 
using hydroponically grown products to sustain air and oxygen 
levels as much as for the nutrition aspect.

Correct me if I'm wrong ( which I know you will).
My new ambition in life:- A 12 second fart which changes
note 4 times and forces the dog to leave the room.
