"This was nomad land. The High Plains—they were black with buffalo from here straight to Canada! The biggest migrating herds of animals ever seen in history. They killed the buffalo off with repeating rifles, in twenty years. It took another hundred fifty years to drain off all the water underground, and of course by then the atmosphere was wrecked too.... But see, it was all a really bad mistake. The people who settled out here—we destroyed this place. And we were destroyed for doing it."
