Tariki and Nanao talked about ecopoesis, which for them was terraforming redefined, subtilized, localized. Transmuted into something like Hiroko’s areoformation. No longer powered by heavy industrial global methods, but by the slow, steady, and intensely local process of working on individual patches of land. “Mars is all a garden. Earth too for that matter. This is what humans have become. So we have to think about gardening, about that level of responsibility to the land. A human-Mars interface that does justice to both.”

Sax waggled a hand uncertainly. “I’m used to thinking of Mars as a kind of wilderness,” he said, as he looked up the etymology of the word garden. French, Teutonic, Old Norse, gard, enclosure. Seemed to share origins with guard, or keeping. But who knew what the supposedly equivalent word in Japanese meant. Etymology was hard enough without translation thrown into the mix. “You know— get things started, let loose the seeds, then watch it all develop on its own. Self-organizing ecologies, you know.”

“Yes,” Tariki said, “but wilderness too is a garden now. A kind of garden. That’s what it means to be what we are.” He shrugged, his forehead wrinkled; he believed the idea was true, but did not seem to like it. “Anyway, ecopoesis is closer to your vision of wilderness than industrial terraforming ever was.”

“Maybe,” Sax said. “Maybe they’re just two stages of a process. Both necessary.”

Tariki nodded, willing to consider it. “And now?”

“It depends on how we want to deal with the possibility of an ice age,” Sax said. “If it’s bad enough, kills off enough plants, then ecopoesis won’t have a chance. The atmosphere could freeze back onto the surface, the whole process crash. Without the mirrors, I’m not confident that the biosphere is robust enough to continue growing. That’s why I want to see those soil labs you have. It may be that industrial work on the atmosphere remains to be done. We’ll have to try some modeling and see.”

Tariki nodded, and Nanao too. Their ecologies were being snowed under, right before their eyes; flakes drifted down through the transient bronze sunlight at this very moment, tumbling in the wind. They were open to suggestion.

Meanwhile, as throughout these drives, their young associates from Da Vinci and Sabishii were running over the massif together, and returning to Sabishii’s mound maze babbling through the night about geomancy and areomancy, ecopoetics, heat exchange, the five elements, greenhouse gases, and so on. A creative ferment that looked to Sax very promising. “Michel should be here,” he said to Nanao. “John should be here. How he would love a group like this.”

And then it occurred to him: “Ann should be here.”

So he went back to Pavonis, leaving the group in Sabishii talking things over.

Back on Pavonis everything was the same. More and more people, spurred on by Art Randolph, were proposing that they hold a constitutional congress. Write an at least provisional constitution, hold a vote on it, then establish the government described.
