They should draft dwarfs and downsize everything. 1/3 the food ,fuel ,oxygen and most everything else. They are intelligent and with excellent dexterity. Whats the downside?
WARNING! WARNING! I don’t believe we’re allowed to say dwarfs or midgets any longer. Little people is the “acceptable” term now. Kinds changes things up for “Snow White and the Seven ‘Little People’” doesn’t it. No more midget tossing. :>}
