“All these issues have been raised before, on Mars. The whole matter of environmental ethics was raised to a new level by the experience on Mars, raised right into the heart of our actions. Now you want to protect this place as wilderness, and I can see why. But I’m a Martian, and so I understand. A lot of you are Martian, or your parents were. You start from that ethical position, and in the end wilderness is an ethical position. Terrans won’t understand you as well as I do. They’ll come out here and build a big casino right on this promontory. They’ll cover this rift from rim to rim, and try terraforming it like they have everywhere else. The Chinese are still jammed into their country like sardines, and they don’t give a damn about the intrinsic worth of China itself, much less a barren moonlet on the edge of the solar system. They need room and they see it’s out here, and they’ll come and build and look at you funny when you object, and what are you going to do? You can try sabotage like the Reds did on Mars, but they can blow you off the moons here just as easy as you can them, and they’ve got a million replacements for every colonist they lose. That’s what we’re talking about when we talk about Earth. We’re like the Lilliputians with Gulliver. We’ve got to work together, and tie him down with as many little lines as we can devise.”

No response from the others.

Zo sighed. “Well,” she said, “maybe it’s for the best. Spread people around out here, they won’t be pressuring Mars so hard. It might be possible to work out deals whereby the Chinese are free to settle out here all they want, and we on Mars are free to cut down immigration to nearly nothing. It might work rather well.”

Again no response from the others.

Finally Ann said, “Shut up. Let us concentrate on the land here.”

“Oh of course.”

Then, as they were approaching the very end of the buttress, the promontory standing out in a gap of air beyond all telling, under the bejeweled jade disk and the brilliant diamond chip beyond it, the whole solar system suddenly triangulated by these celestial objects, the true size of things revealed— they saw moving stars overhead. The rocket jets of their spacecraft.

“See?” Zo said. “It’s the Chinese, coming to have a look.”
