"I know the signs, David. The pollution's catching up to us faster than anyone knows. There's more radiation in the atmosphere than there's been since Hiroshima— French tests, China's tests. Leaks. God knows where all of it's coming from. We reached zero population growth a couple of years ago, but, David, we were trying, and other nations are getting there too, and they aren't trying. There's famine in one-fourth of the world right now. Not ten years from now, not six months from now. The famines are here and they've been here for three, four years already, and they're getting worse. There're more diseases than there's ever been since the good Lord sent the plagues to visit the Egyptians. And they're plagues that we don't know anything about.

"There's more drought and more flooding than there's ever been. England's changing into a desert, the bogs and moors are drying up. Entire species of fish are gone, just damn gone, and in only a year or two. The anchovies are gone. The codfish industry is gone. The cod they are catching are diseased, unfit to use. There's no fishing off the west coast of the Americas.

"Every damn protein crop on earth has some sort of blight that gets worse and worse. Corn blight. Wheat rust. Soybean blight. We're restricting our exports of food now, and next year we'll stop them altogether. We're having shortages no one ever dreamed of. Tin, copper, aluminum, paper. Chlorine, by God! And what do you think will happen in the world when we suddenly can't even purify our drinking water?"

His face was darkening as he spoke, and he was getting angrier and angrier, directing his unanswerable questions to David, who stared at him with nothing at all to say.

"And they don't know what to do about any of it," his grandfather went on. "No more than the dinosaurs knew how to stop their own extinction. We've changed the photochemical reactions of our own atmosphere, and we can't adapt to the new radiations fast enough to survive! There have been hints here and there that this is a major concern, but who listens? The damn fools will lay each and every catastrophe at the foot of a local condition and turn their backs on the fact that this is global, until it's too late to do anything."

"But if it's what you think, what could they do?" David asked, looking to Dr. Walt for support and finding none.

"Turn off the factories, ground the airplanes, stop the mining, junk the cars. But they won't, and even if they did, it would still be a catastrophe. It's going to break wide open. Within the next couple of years, David, it's going to break." He drank his eggnog then and put the crystal cup down hard. David jumped at the noise.
