     They could have taken some pointers from George O. Smith's _Venus   
   Equilateral_ in which a space station's "air plant" comprised many trays of   
   "Martian sawgrass", an especially hardy plant bred to produce oxygen, also   
   capable of handling cigar smoke and    
   solder fumes as well as human exhalations.   
      
     Unlike the algae used in some SF as combination air regenerator/food source,   
   Smith's sawgrass was not intended to be eaten.
