Parkeson scolded on. “I know the question that’s foremost in your minds,” his voice continued, “but you’d better forget it. Let me tell you what happens if this line isn’t finished by sundown. (But by God, it will be finished!) Listen, you wanted women. All right, now you’ve all been over to visit the uh—‘affectionate institution’—and you got what you wanted; and now the work is behind schedule. Who gives a damn about the project, eh? I know what you’re thinking. ‘That’s Parkeson’s worry.’ OK, so let’s talk about what you’re going to breathe for the next couple of periods. Let’s talk about how many men will wind up in the psycho-respiratory ward, about the overload on the algae tanks. That’s not your responsibility either, is it? You don’t have to breathe and eat. Hell, let Nature take care of air and water, eh? Sure. Now look around. Take a good look. All that’s between you and that hungry vacuum out there is ten pounds of man-made air and a little reinforced plastic. All that keeps you eating and drinking and breathing is that precarious life-cycle of ours at Copernicus. That plant-animal feedback loop is so delicately balanced that the biology team gets the cold shakes every time somebody sneezes or passes gas. It has to be constantly nursed. It has to be planned and kept on schedule. On Earth, Nature’s a plenum. You can chop down her forests, kill of} her deer and buffalo, and fill her air with smog and hot isotopes; the worst you can do is cause a few new deserts and dust bowls, and make things a little unpleasant for a while.
“Up here, we’ve got a little, bit of Nature cooped up in a bottle, and we’re in the bottle too. We’re cultured like mold on agar. The biology team has to chart the ecology for months in advance. It has to know the construction and survey teams are going to deliver exactly what they promise to deliver, and do it on schedule. If you don’t deliver, the ecology gets sick. If the ecology gets sick, you get sick.
“Do you want another epidemic of the chokers like we had three years back? That’s what’ll happen if there’s a work slowdown while everybody goes off on a sex binge at that ship. If the line isn’t finished before sundown, the ecology gets bled for another two weeks to keep that mine colony going, and the colony can’t return wastes to our cycle. Think it over, but think fast. There’s not much time. ‘We all breathe the same air’—on Earth, that’s just a political slogan. Here, we all breathe it or we all choke in it. How do you want it, men?”
