Even Michel had to admit it. “Population pressures,” he said, trying to wave them away. “There are too many people down there, and more all the time. You saw what it was like during our visit. As long as Earth is in that situation, Mars is under threat. And so we fight up here too.”
Sax took the point. In a way it was comforting; human behavior not as irreducibly evil or stupid, but as responding, semirationally, to a given historical situation, a danger. Seizing what one could, with the notion that there might not be enough for all; doing everything possible to protect one’s offspring; which of course endangered all offspring, by the aggregate of individual selfish actions. But at least it could be called an attempt at reason, a first approximation.
“It’s not as bad as it was, anyway,” Michel was saying. “Even on Earth people are having far fewer children. And they’re reorganizing into collectives pretty well, considering the flood and all the trouble that preceded it. A lot of new social movements down there, a lot of them inspired by what we’re doing here. And by what Nirgal does. They’re still watching him and listening to him, even when he doesn’t speak. What he said during our visit there is still having a big effect.”
“I believe it.”
“Well, there you are! It’s getting better, you have to admit it. And when the longevity treatments stop working, there will come a balance of births and deaths.”
“We’ll hit that time soon,” Sax predicted glumly.
“Why do you say so?”
“Signs of it cropping up. People dying from one thing or other. Senescence is not a simple matter. Staying alive when senescence should have kicked in— it’s a wonder we’ve done as much as we have. There’s probably a purpose in senescence. Avoiding overpopulation, perhaps. Making room for new genetic material.”
“That bodes poorly for us.”
“We’re already over two hundred percent the old average lifetime.”
“Granted, but even so. One doesn’t want it to end just because of that.”
“No. But we have to focus on the moment. Speaking of which, why don’t you come out into the field with me? I’ll be as upbeat as you want out there. It’s very interesting.”
“I’ll try to free up some time. I’ve got a lot of clients.”
“You’ve got a lot of free time. You’ll see.”

In this particular moment, the sun was high. Rounded white clouds were piling up in the air overhead, forming great masses that would never come again, though at the moment they were as solid as marble, and darkening at their bottoms. Cumulonimbus. He was standing on Da Vinci Peninsula’s western cliff again, looking across Shalbatana Fjord to the cliff edging the east side of Lunae Planum. Behind him rose the flat-topped hill that was the rim of Da Vinci Crater. Home base. He had lived there a long time now. These days their co-op was making many of the satellites being put up into orbit, and the boosters as well, in collaboration with Spencer’s lab in Odessa, and a great number of other places. A Mondragon-style cooperative, operating the ring of labs and homes in the rim, and the fields and lake filling the crater floor. Some of them chafed at restrictions imposed by the courts on projects they had in mind, involving new power plants that would put out too much heat. In the last few years the GEC had been issuing K rations, as they were called, giving communities the right to add some fraction of a degree Kelvin to the global warming. Some Red communities were doing their best to get assigned K rations and then not use them. This action, along with ongoing incidences of ecotage, kept the global temperature from rising very fast no matter what other communities did. Or so the other communities argued. But the ecocourts were still parsimonious with the K rations. Cases were judged by a provincial ecocourt, then the judgment was approved by the GEC, and that was it: no appeals, unless you could get a petition signed by fifty other communities, and even then the appeal was only dropped into the morass of the global legislature, where its fate was up to the undisciplined crowd in the duma.
Slow progress. Just as well. With the global average temperatures above freezing, Sax was content. Without the constraint of the GEC, things could easily get too warm. No, he was in no further hurry. He had become an advocate of stabilization.
Now, out in the sun of a perihelion day, it was an invigorating 281 K, and he was walking along the sea-cliff edge of Da Vinci, looking at alpine flowers in the cracks of the rubble, then past them to the distant quantum sheen of the fjord’s sunny surface, when down the cliff edge walking his way came a tall woman, wearing a face mask and jumper, and big hiking boots: Ann. He recognized her instantly— that stride, no doubt about it— Ann Clayborne, in the flesh.
