“...the supply of uranium in the planet is very limited, and it is feared that it may be used up before the human race is exterminated, but if the practically unlimited supply of hydrogen in the sea could be utilized there would be considerable reason to hope that homo sapiens might put an end to himself, to the great advantage of the other less ferocious animals.”

“Jimmy, look at it realistically. You can't couple a minimum access to food with an expanding population indefinitely. Homo sapiens doesn't seem to be able to cut himself off at the supply end. He's one of the few species that doesn't limit reproduction in the face of dwindling resources. In other words - and up to a point, of course - the less we eat, the more we fuck.""How to do you account for that?" said Jimmy"Imagination," said Crake.
