The man grimaced. "We tried it once for three months. We holed up at the South Pole and waited. They didn't notice it. Some drafting-room people were missing, some chief nurses didn't show up, minor government people on the non-policy level couldn't be located. It didn't seem to matter.
"In a week there was hunger. In two weeks there were famine and plague, in three weeks war and anarchy. We called off the experiment; it took us most of the next generation to get things squared away again."
"But why didn't you let them kill each other off?"
"Five billion corpses mean about five hundred million tons of rotting flesh."
Barlow had another idea. "Why don't you sterilize them?"
"Two and one-half billion operations is a lot of operations. Because they breed continuously, the job would never be done."
"I see. Like the marching Chinese!"
"Who the devil are they?"
"It was a—uh—paradox of my time. Somebody figured out that if all the Chinese in the world were to line up four abreast, I think it was, and start marching past a given point, they'd never stop because of the babies that would be born and grow up before they passed the point."
"That's right. Only instead of 'a given point,' make it 'the largest conceivable number of operating rooms that we could build and staff.' There could never be enough."
