Green mars (10 page)

Sam and Max nodded as if this were the usual way to start a meeting.

“Can I take notes?” Art asked.

“Please,” Fort said. He gestured at the coffee table in the middle of the square of couches, which was covered with papers and lecterns. “I want to play some games later, so there’s lecterns and workpads, whatever you like.”

Most of them had brought their own lecterns, and there was a short silent scramble as they got them out and running. While they were at it Fort stood up and began walking in a circle behind their couches, making a revolution every few sentences.

“We now use about eighty percent of the net primary product of land-based photosynthesis,” he said. “One hundred percent is probably impossible to reach, and our long-range carrying capacity has been estimated to be thirty percent, so we are massively overshot, as they say. We have been liquidating our natural capital as if it were disposable income, and are nearing depletion of certain capital stocks, like oil, wood, soil, metals, fresh water, fish, and animals. This makes continued economic expansion difficult.”

Difficult! Art wrote. Continued?

“We have to continue,” Fort said, with a piercing glance at Art, who unobtrusively sheltered his lectern with his arm. “Continuous expansion is a fundamental tenet of economics. Therefore one of the fundamentals of the universe itself. Because everything is economics. Physics is cosmic economics, biology is cellular economics, the humanities are social economics, psychology is mental economics, and so on.”

His listeners nodded unhappily.

“So everything is expanding. But it can’t happen in contradiction to the law of conservation of matter-energy. No matter how efficient your throughput is, you can’t get an output larger than the input.”

Art wrote on his note page, Output larger than input—everything economics—natural capital—Massively Overshot.

“In response to this situation, a group here in Praxis has been working on what we call full-world economics.”

“Shouldn’t that be overfull-world?” Art asked.

Fort didn’t appear to hear him. “Now as Daly said, man-made capital and natural capital are not substitutable. This is obvious, but since most economists still say they are substitutable, it has to be insisted on. Put simply, you can’t substitute more sawmills for fewer forests. If you’re building a house you can juggle the number of power saws and carpenters, which means they’re substitutable, but you can’t build it with half the amount of lumber, no matter how many saws or carpenters you have. Try it and you have a house of air. And that’s where we live now.”

Art shook his head and looked down at his lectern page, which he had filled again. Resources and capital nonsubstitutable—power saws/carpenters— house of air.

“Excuse me?” Sam said. “-Did you say natural capital?”

Fort jerked, turned around to look at Sam. “Yes?”

“I thought capital was by definition man-made. The produced means of production, we were taught to define it.”

“Yes. But in a capitalist world, the word capital has taken on more and more uses. People talk about human capital, for instance, which is what labor accumulates through education and work experience. Human capital differs from the classic kind in that you can’t inherit it, and it can only be rented, not bought or sold.”

“Unless you count slavery,” Art said.

Fort’s forehead wrinkled. “This concept of natural capital actually resembles the traditional definition more than human capital. It can be owned and bequeathed, and divided into renewable and nonrenewable, marketed and nonmarketed.”

“But if everything is capital of one sort or another,” Amy said, “you can see why people would think that one kind was substi-tutable for another kind. If you improve your man-made capital to use less natural capital, isn’t that a substitution?”

Fort shook his head. “That’s efficiency. .Capital is a quantity of input, and efficiency is a ratio of output to input. No matter how efficient capital is, it can’t make something out of nothing.”

“New energy sources ...” Max suggested.

“But we can’t make soil out of electricity. Fusion power and self-replicating machinery have given us enormous amounts of power, but we have to have basic stocks to apply that power to. And that’s where we run into a limit for which there are no substitutions possible.”

Fort stared at them all, still displaying that primate calm that Art had noted at the beginning. Art glanced at his lectern screen. Natural capital—human capital—traditional capital—energy vs. matter—electric soil—no substitutes please—He grimaced and clicked to a new page.

Fort said, “Unfortunately, most economists are still working within the empty world model of economics.”

“The full-world model seems obvious,” Sally said. “It’s just common sense. Why would any economist ignore it?”

Fort shrugged, made another silent circumnavigation of the room. Art’s neck was getting tired.

“We understand the world through paradigms. The change from empty-world economics to full-world economics is a major paradigm shift. Max Planck once said that a new paradigm takes over not when it convinces its opponents, but when its opponents eventually die.”

“And now they aren’t dying,” Art said.

Fort nodded. “The treatments are keeping people around. And a lot of them have tenure.”

Sally looked disgusted. “Then they’ll have to learn to change their minds, won’t they.”

Fort stared at her. “We’ll try that right now. In theory at least. I want you to invent full-world economic strategies. It’s a game I play. If you plug your lecterns into the table, I can give you the starting data.”

They all leaned forward and plugged into the table.

The first game Fort wanted to play involved estimating maximum sustainable human populations. “Doesn’t that depend on assumptions about lifestyle?” Sam asked.

“We’ll make a whole range of assumptions.”

He wasn’t kidding. They went from scenarios in which Earth’s every acre of arable land was farmed with maximum efficiency, to scenarios involving a return to hunting and gathering; from universal conspicuous consumption, to universal subsistence diets. Their lecterns set the initial conditions and then they tapped away, looking bored or nervous or impatient or absorbed, using formulas provided by the table, or else supplying some of their own.

It occupied them until lunch, and then all afternoon. Art enjoyed games, and he and Amy always finished well ahead of the others. Their results for a maximum sustainable population ranged from a hundred million (the “immortal tiger” model, as Fort called it) to thirty billion (the “ant farm” model).

“That’s a big range,” Sam noted.

Fort nodded, and eyed them patiently.

“But if you look only at models with the most realistic conditions,” Art said, “you usually get between three and eight billion.”

“And the current population is about twelve billion,” Fort said. “So, say we’re overshot. Now what do we do about that? We’ve got companies to run, after all. Business isn’t going to stop because there’s too many people. Full-wo rid economics isn’t the end of economics, it’s just the end of business as usual. I want Praxis to be ahead of the curve on this. So. It’s low tide, and I’m going back out. You’re welcome to join me. Tomorrow we’ll play a game called Overfull.”

With that he left the room, and they were on their own. They went back to their rooms, and then, as it was close to dinnertime, to the dining hall. Fort was not there, but several of his elderly associates from the night before were; and joining them tonight was a crowd of young men and women, all of them lean, bright-faced, healthy-looking. They looked like a track club or a swim team, and more than half were women. Sam’s and Max’s eyebrows shot up and down in a simple Morse code, spelling “Ah ha! Ah ha!” The young men and women ignored that and served them dinner, then returned to the kitchen. Art ate quickly, wondering if Sam and Max were correct in their suppositions. Then he took his plate into the kitchen and started to help at the dishwasher, and said to one of the young women, “What brings you here?”

“It’s a kind of scholarship program,” she said. Her name was Joyce. “We’re all apprentices who joined Praxis last year, and we were selected to come here for classes.”

“Were you by chance working on full-world economics today?”

“No, volleyball.”

Art went back outside, wishing he had gotten selected to their program rather than his. He wondered if there was some big hot-tub facility, down there overlooking the ocean. It did not seem impossible; the ocean here was cool, and if everything was economics, it could be seen as an investment. Maintaining the human infrastructure, so to speak.

Back in the residence, his fellow guests were talking the day over. “I hate this kind of stuff,” said Sam.

“We’re stuck with it,” Max said gloomily. “It’s join a cult or lose your job.”

The others were not so pessimistic. “Maybe he’s just lonely,” Amy suggested.

Sam and Max rolled their eyes and glanced toward the kitchen.

“Maybe he always wanted to be a teacher,” Sally said.

“Maybe he wants to keep Praxis growing ten percent per year,” George said, “full world or not.”

Sam and Max nodded at this, and Elizabeth looked annoyed. “Maybe he wants to save the world!” she said.

“Right,” Sam said, and Max and George snickered.

“Maybe he’s got this room bugged,” Art said, which cut short the conversation like a guillotine.

The days that followed were much like the first one. They sat in the conference room, and Fort circled them and talked through the mornings, sometimes coherently, sometimes not. One morning he spent three hours talking about feudalism—how it was the clearest political expression of primate dominance dynamics, how it had never really gone away, how transnational capitalism was feudalism writ large, how the aristocracy of the world had to figure out how to subsume capitalist growth within the steady-state stability of the feudal model. Another morning he talked about a caloric theory of value called eco-economics, apparently first worked out by early settlers on Mars; Sam and Max rolled their eyes at that news, while Fort droned on about Taneev and Tokareva equations, scribbling illegibly on a drawing board in the corner.

But this pattern didn’t last, because a few days after their arrival a big swell came in from the south, and Fort canceled their meetings and spent all his time surfing or skimming over the, waves in a birdsuit, which was a light broad-winged bodysuit, a flexible fly-by-wire hang glider that translated the flyer’s muscle movements into the proper semi-rigid configurations for successful flight. Most of the young scholarship winners joined him in the air, swooping around like Icaruses, and then dropping in and planing swiftly over the cushions of air pushed up by every breaking wave, air surfing just like the pelicans that had invented the sport.

Art went out and thrashed around on a body board, enjoying the water, which was chill, but not so much as to absolutely require a wetsuit. He hung out near the break that Joyce surfed, and chatted with her between sets, and found out that the other ancient kitchen workers were good friends of Fort’s, veterans of the first years of Praxis’s rise to prominence. The young scholars referred to them as the Eighteen Immortals. Some of the Eighteen were based at the camp, while others dropped by for a kind of ongoing reunion, conferring about problems, advising the current Praxis leadership on policy, running seminars and classes, and playing in the waves. Those who didn’t care for the water worked in the gardens.

Art inspected the gardeners closely as he hiked back up to the compound. They worked in something resembling slow motion, talking to each other all the while. Currently the main task appeared to be harvesting the tortured apple bushes.

The south swell subsided, and Fort reconvened Art’s group. One day the topic was Full-World Business Opportunities, and Art began to see why he and his six fellows might have been chosen to attend: Amy and George worked in contraception, Sam and Max in industrial design, Sally and Elizabeth in agricultural technology, and he himself in resource recovery. They all worked in full-world businesses already, and in the afternoon’s games they proved fairly good at designing new ones.

Another day Fort proposed a game in which they solved the full-world problem by returning to an empty world. They were to suppose the release of a plague vector that would kill- everyone in the world who had not had the gerontological treatment. What would the pros and cons of such an action be?

The group stared at their lecterns, nonplussed. Elizabeth declared that she wouldn’t play a game based on such a monstrous idea.

“It is a monstrous idea,” Fort agreed. “But that doesn’t make it impossible. I hear things, you see. Conversations at certain levels. Among the leadership of the big transnationals, for instance, there are discussions. Arguments. You hear all kinds of ideas put out quite seriously, including some like this one. Everyone deplores them, and the subject changes. But no one claims that they are technically impossible. And some seem to think that they would solve certain problems that otherwise are unsolvable.”

The group considered this thought unhappily. Art suggested that agricultural workers would be in short supply.
