Someone in the crowd stood and asked him about the possibility of a population explosion, and he nodded. “Yes of course. This is a real problem. You don’t have to be a demographer to see that if new ones continue being born while the elderly are not dying, population will quickly soar to incredible levels. Unsustainable levels, until there will be a crash. So. This has to be faced now. The birth rate simply has to be cut, at least for a while. It isn’t a situation that has to last forever. The longevity treatments are not immortality treatments. Eventually the first generations given the treatment will die. And therein lies the solution to the problem. Say the current population on the two worlds is fifteen billion. That means we’re already starting from a bad spot. Given the severity of the problem, as long as you get to be a parent at all, there is no reason to complain; it’s your own longevity causing the problem after all, and parenthood is parenthood, one child or ten. So say that each person partners, and the two parents have only a single child, so that there is one child for every two people in the previous generation. Say that means seven and a half billion children out of this present generation. And they are all given the longevity treatment too, of course, and cosseted until they are no doubt the insufferable royalty of the world. And they go on to have four billion children, the new royalty, and that generation has two, and so on. All of them are alive at once, and the population is rising all the time, but at a lower rate as time passes. And then at some point, maybe a hundred years from now, maybe a thousand years from now, that first generation will die. It may happen over a fairly short period of time, but fast or slow, when the process is done, the overall population will be almost halved. At that point people can look at the situation, the infrastructure, the environments of the two worlds— the carrying capacity of the entire solar system, whatever that might be. After the biggest generations are gone, people can start having two children each, perhaps, so that there is replacement, and a steady state. Or whatever. When they have that kind of choice, the population crisis will be over. It could take a thousand years.”
Nirgal stopped to look outside of himself, to stare around at the audience; people watching him rapt, silent. He gestured with a hand, to draw them all together. “In the meantime, we have to help each other. We have to regulate ourselves, we have to take care of the land. And it’s here, in this part of the project, that Mars can help Earth. First, we are an experiment in taking care of the land. Everyone learns from that, and some lessons can be applied here. Then, more importantly, though most of the population will always be located here on Earth, a goodly fraction of it can move to Mars. It will help ease the situation, and we’ll be happy to take them. We have an obligation to take on as many people as we possibly can, because we on Mars are Terrans still, and we are all in this together. Earth and Mars— and there are other habitable worlds in the solar system as well, none as big as our two, but there are a lot of them. And by using them all, and cooperating, we can get through the populated years. And walk out into a golden age.”

That day’s talk made quite an impression, as far as one could tell from within the eye of the media storm. Nirgal conversed for hours every day after that, with group after group, elaborating the ideas he had first expressed in that meeting. It was exhausting work, and after a few weeks of it without any letup, he looked out his bedroom window one cloudless morning, and went out and talked to his escort about making an expedition. And the escort agreed to tell the people in Bern he was touring privately; and they took a train up into the Alps.
The train ran south from Bern, past a long blue lake called the Thuner See, which was flanked by steep grassy alps, and ramparts and spires of gray granite. The lakeside towns were topped by slate roof tiles, dominated by ancient trees and an occasional castle, everything in perfect repair. The vast green pastures between the towns were dotted by big wooden farmhouses, with red carnations in flower boxes at every window and balcony. It was a style that had not changed in five hundred years, the escorts told him. Settling into the land, as if natural to it. The green alps had been cleared of trees and stones— in their original state they had been forests. So they were terraformed spaces, huge hilly lawns that had been created to provide forage for cattle. Such an agriculture had not made economic sense as capitalism defined it, but the Swiss had supported the high farms anyway, because they thought it was important, or beautiful, or both at once. It was Swiss. “There are values higher than economic values,” Vlad had insisted back in the congress on Mars, and Nirgal saw now how there were people on Earth who had always believed that, at least in part. Werteswandel, they were saying down in Bern, mutation of values; but it could as well be evolution of values, return of values; gradual change, rather than punctuated equilibrium; benevolent residual archaisms, which endured and endured, until slowly these high isolated mountain valleys had taught the world how to live, their big farmhouses floating by on green waves. A shaft of yellow sun split the clouds and struck the hill behind one such farm, and the alp gleamed in an emerald mass, so intensely green that Nirgal felt disoriented, then actually dizzy; it was hard to focus on such a radiant green!
The heraldic hill disappeared. Others appeared in the window, wave after green wave, luminous with their own reality. At the town of Interlaken the train turned and began to ascend a valley so steep that in places the tracks entered tunnels into the rocky sides of the valley, and spiraled a full 360 degrees inside the mountain before coming back out into the sun, the head of the train right above the tail. The train ran on tracks rather than pistes because the Swiss had not been convinced that the new technology was enough of an improvement to justify replacing what they already had. And so the train vibrated, and even rocked side to side, as it rumbled and squealed uphill, steel on steel.
They stopped in Grindelwald, and in the station Nirgal followed his escort onto a much smaller train, which led them up and under the immense north wall of the Eiger. Underneath this wall of stone it appeared only a few hundred meters tall; Nirgal had gotten a better sense of its great height fifty kilometers away, in Bern’s Monster. Now, here, he waited patiently as the little train hummed into a tunnel in the mountain itself, and began to make its spirals and switchbacks in the darkness, punctuated only by the interior lights of the train, and the brief light from a single side tunnel. His escort, about ten men strong, spoke among themselves in low guttural Swiss German.
When they emerged into the light again they were in a little station called the Jungfraujoch, “the highest train station in Europe” as a sign in six languages said— and no wonder, as it was located in an icy pass between the two great peaks the Monch and the Jungfrau, at 3,454 meters above sea level, with no point or destination but its own.
Nirgal got off the train, trailed by his escort, and went out of the station onto a narrow terrace outside the building. The air was thin, clean, crisp, about 270 K— the best air Nirgal had breathed since he left Mars, it brought tears to his eyes it felt so familiar! Ah, now this was a place!
Even with sunglasses on the light was extremely bright. The sky was a dark cobalt. Snow covere d most of the mountainsides, but granite thrust through the snow everywhere, especially on the north sides of the great masses, where the cliffs were too steep to hold snow. Up here the Alps no longer resembled an escarpment at all; each mass of rock had its own look and presence, separated from the rest by deep expanses of empty air, including glacial valleys that were enormously deep U gaps. To the north these macrotrenches were very far below, and green, or even filled with lakes. To the south, however, they were high, and filled only with snow and ice and rock. On this day the wind was pouring up from this south side, bringing the chill of the ice with it.
Down the ice valley directly south of the pass, Nirgal could see a huge crumpled white plateau, where glaciers poured in from the surrounding high basins to meet in a great confluence. This was Concordiaplatz, they told him. Four big glaciers met, then poured south in the Grosser Aletschgletscher,
the longest glacier in Switzerland.
Nirgal moved down the terrace to its end, to see farther into this wilderness of ice. At the far end he found that there was a staircase trail, hacked into the hard snow of the south wall where it rose to the pass. It was a path down to the glacier below them, and from there to Concordiaplatz.
Nirgal asked his escorts to stay in the station and wait for him; he wanted to hike alone. They protested, but the glacier in summer was free of snow, the crevasses all obvious, and the trail well clear of them. And no one else was down there on this cold summer day. Nevertheless the members of the escort were uncertain, and two insisted on coming with him, at least part way, and at a distance behind—”just in case.”
Finally Nirgal nodded at the compromise, and pulled on his hood, and hiked down the ice stairs, thumping down painfully until he was on the flatter expanse of the Jungfraufirn. The ridges that walled this snow valley ran south from the Jungfrau and the Monch respectively, then after a few high kilometers dropped abruptly to Concordiaplatz. From the trail their rock looked black, perhaps in contrast to the whiteness of the snow. Here and there were patches of faint pinkness in the white snow— algae. Life even here— but barely. It was for the most part a pure expanse of white and black, and the overarching dome of Prussian blue, with a cold wind funneling up the canyon from Concordiaplatz. He wanted to make it down to Concordiaplatz and have a look around, but he couldn’t tell whether the day would give him enough time or not; it was very difficult to judge how far away things were, it could easily have been farther than it looked. But he could go until the sun was halfway to the western horizon, and then turn back; and so he hiked swiftly downhill over the firn, from orange wand to orange wand, feeling the extra person inside him, feeling also the two members of the escort who were tagging along some two hundred meters behind.
For a long time he just walked. It wasn’t so hard. The crenellated ice surface crunched under his brown boots. The sun had softened the top layer, despite the cool wind. The surface was too bright to see properly, even with sunglasses; the ice joggled as he walked, and glowed blackly.
The ridges to left and right began their drop. He came out into Concordiaplatz. He could see up glaciers into other high canyons, as if up ice fingers of a hand held up to the sun. The wrist ran down to the south, the Grosser Aletschgletscher. He was standing in the white palm, offered to the sun, next to a lifeline of rubble. The ice out here was pitted and gnarly and bluish in tone.
A wind picked at him, and swirled through his heart; he turned around slowly, like a little planet, like a top about to fall, trying to take it in, to face it. So big, so bright, so windy and vast, so crushingly heavy— the sheer mass of the white world!— and yet with a kind of darkness behind it, as of space’s vacuum, there visible behind the sky. He took off his sunglasses to see what it really looked like, and the glare was so immediate and violent that he had to close his eyes, to cover his face in the crook of his arm; still great white bars pulsed in his vision, and even the afterimage hurt in its blinding intensity. “Wow!” he shouted, and laughed, determined to try it again as soon as the afterimages lessened, but before his pupils had again expanded. So he did, but the second attempt was as bad as the first. How dare you try to look on me as I really am! the world shouted silently. “My God.” With feeling. “Ka wow.”
He put his sunglasses back on his closed eyes, looked out through the bounding afterimages; gradually the primeval landscape of ice and rock restabilized out of the pulsing bars of black and white and neon green. The white and the green; and this was the white. The blank world of the inanimate universe. This place had precisely the same import as the primal Martian landscape. Just as big as it was on Mars, yes, and even bigger, because of the distant horizons, and the crushing gravity; and steeper; and whiter; and windier, ka, it pierced so chill through his parka, even windier, even colder— ah God, like a wind lancing through his heart: the sudden knowledge that Earth was so vast that in its variety it had regions that even out-Marsed Mars itself— that among all the ways that it was greater, it was greater even at being Martian.
He was brought still by this thought. He only stood and stared, tried to face it. The wind died for the moment. The world too was still. No movement, no sound.
When he noticed the silence he began paying attention to it, listening for something, hearing nothing, so that the silence itself somehow became more and more palpable. It was unlike anything he had ever heard before. He thought about it; on Mars he had always been in tents or in suits— always in machinery, except for during the rare walks on the surface he had made in recent years. But then there had always been the wind, or machines nearby. Or he simply hadn’t noticed. Now there was only the great silence, the silence of the universe itself. No dream could imagine it.
And then he began to hear sounds again. The blood in his ears. His breath in his nose. The quiet whir of his thinking— it seemed to have a sound. His own support system this time, his body, with its organic pumps and ventilators and generators. The mechanisms were all still there, provided inside him, making their noises. But now he was free of anything more, in a great silence where he could actually hear himself quite well, just himself on this world alone, a free body standing on its mother earth, free in the rock and ice where it had all begun. Mother Earth— he thought of Hiroko— and this time without the tearing grief that he had felt in Trinidad. When he returned to Mars, he could live like this. He could walk out in the silence a free being, live outdoors in the wind, in something like this pure vast lifeless whiteness, with something like this dark blue dome overhead, the blue a visible exhalation of life itself— oxygen, life’s own color. Up there doming the whiteness. A sign, somehow. The white and the green, except here the green was blue.
With shadows. Among the faint lingering afterimages lay long shadows, running from the west. He was a long way from Jungfraujoch, and considerably lower as well. He turned and began hiking up the Jungfraufirn. In the distance, up the trail, his two companions nodded and turned uphill themselves, hiking fast.
Soon enough they were in the shadow of the ridge to the west, the sun now out of sight for good on this day, and the wind swirling over his back, helping on. Cold indeed. But it was his kind of temperature, after all, and his kind of air, just a nice touch of extra thickness to it; and so despite the weight inside him he began to trudge on up the crunchy hardpack in a little jog, leaning into it, feeling his thigh muscles respond to the challenge, fall into their old lung-gom-pa rhythm, with his lungs pumping hard and his heart as well, to handle the extra weight. But he was strong, strong, and this was one of Earth’s little high regions of Marsness; and so he crunched up the firn feeling stronger by the minute, also appalled, exhilarated— awed— it was a most astonishing planet, that could have so much of the white and so much of the green as well, its orbit so exquisitely situated that at sea level the green burst out and at three thousand meters the white blanketed it utterly— the natural zone of life just that three thousand meters wide, more or less. And Earth rolled right in the middle of that filmy bubble biosphere, in the right few thousand meters out of an orbit 150 million kilometers wide. It was too lucky to be believed.
His skin began to tingle with the effort, he was warm all over, even his toes. Beginning to sweat. The cold air was deliciously invigorating, he felt he was in a pace that he could sustain for hours; but alas, he would not need to; ahead and a bit above lay the snow staircase, with its rope-and-stanchion railing. His guides were making good time ahead of him, hurrying up the final slope. Soon he too would be there, in the little train station/space station. These Swiss, what they thought to build! To be able to visit the stupendous Concordiaplatz, on a day trip from the nation’s capital! No wonder they were so sympathetic to Mars— they were Earth’s closest thing to Martians, truly— builders, terraformers, inhabitants of the thin cold air.
So he was feeling very benevolent toward them when he stepped onto the terrace and then burst into the st
ation, where he began immediately steaming; and when he walked over to his group of escorts and the other passengers who were waiting next to the little train, he was beaming so completely, he was so high, that the impatient frowns of the group (he saw that they had been kept waiting) cracked, and they looked at each other and laughed, shaking their heads as if to say to each other, What can you do? You could only grin and let it happen— they had all been young in the high Alps for the first time, one sunny summer day, and had felt that same enthusiasm— they remembered what it was like. And so they shook his hand, they embraced him— they led him onto the little train and got going, for no matter the event, it was not good to keep a train waiting— and once under way they remarked on his hot hands and face, and asked him where he had gone, and told him how many kilometers that was, and how many vertical meters. They passed him a little hip flask of schnapps. And then as the train went by the little side tunnel that ran out onto the north face of the Eiger, they told him the story of the failed rescue attempt of the doomed Nazi climbers, excited, moved that he was so impressed. And after that they settled into the lit compartments of the train, squealing down through its rough granite tunnel.
Nirgal stood at the end of one car, looking out at the dynamited rock as it flashed past, and then as they burst back into sunlight, up at the looming wall of the Eiger overhead. A passenger walked by him on the way to the next car, then stopped and stared: “Amazing to see you here, I must say.” He had a British accent of some kind. “I just ran into your mother last week.”
Confused, Nirgal said, “My mother?”
“Yes, Hiroko Ai. Isn’t that right? She was in England, working with people at the mouth of the Thames. I saw her on my way here. Quite a coincidence running into you too, I must say. Makes me think I’ll start seeing little red men any second now.”
