Alan Moore talks about Crossed +100

Excerpt from an interview published on BleedingCool site (here) 

How did you come up with the “future” of Crossed and extrapolate what things would be like 100 years after the outbreak?
Alan Moore:  To start with, it would make a huge impact if all human industry were to stop dead in 2008. I’ve tried to think all this through. I’ve tried to come up with an estimate of around 7 billion people on the planet, and I followed Garth’s estimate in one of his “Fatal Englishman” stories, where he outlined the numbers that had been infected and the numbers that had survived, and extrapolated that across the planet. There would be a massive depopulation and a lot people would just be killed. The majority of survivors would be infected and there would be just tiny groups of uninfected human beings, however, given time, those trends would start to reverse.

The main thing is that the Crossed are extraordinarily stupid. And do not have any survival instincts. Humans do have survival instincts, and those who have survived might have done so because they’ve gotten to a place of relative safety, somewhere that can be defended, somewhere that was isolated enough not to be a problem. They would have presumably gotten better at surviving if they’ve managed to survive. The Crossed, on the other hand, would start dying off in extraordinary numbers. Mind you, there are extraordinary numbers of them, so that wouldn’t be as much of a consolation for the human survivors for a considerable time. But the first bad winter would kill an awful lot of the Crossed who hadn’t already died from starvation, stupidity, or their own colleagues.

the problem with the Crossed, they can’t really have children. They are not going to survive. We allowed that there might be a tiny, tiny percentage that might select for not killing their own children. That you might get small, isolated outposts of inbred Crossed, that this was a possibility. But the others would be dying off in extraordinary numbers. And we worked out that certain tipping points would come.

There’d be a time when the population of humans was starting to expand, the population of Crossed was receding dramatically, and also that a lot of the Crossed children that somehow managed to survive—if it happened in 2008—are going to be by 2060 relatively old Crossed. And they are not going to have been looking after themselves. So they are going to be easier to deal with, they are going to be less numerous, and I can see that from around that time, that you are going to start to get humans being able to have relatively defended settlements and would possibly start concerted efforts to “clean” various cities of what remaining Crossed there were.

Now there are still not many remaining people, and they are scattered in settlements across the world. But this was the basic premise. Vegetation would have altered. Most cities, as far as I understand it, would have been colonized by Buddleia, within 4 or 5 years. That would colonize most of our urban centers, and that brings in the butterflies, and most of the insects, which brings in the birds, which brings in other predators. And with the species that had escaped from botanical gardens and zoos, a lot of our western cities would be pretty tropical.
