"A guiding principle will be to keep the world population as small as possible so as not to get into the same problems we face now," Geryl said, adding that the group is currently looking for sponsors and hopes to move to Africa in 2011. "There is too little oil, too little grain in the world now. Those are the kinds of problems we want to avoid."
One of the group's members, Jan, a 57-year-old carpenter from Amsterdam whose name has been changed because he doesn't want to be identified in the press, recently drove five hours to attend one of Geryl's meetings in Antwerp.
"I thought, if there's a chance that we can start a new civilization, I want to contribute," Jan told ABC News. "Because whether I make it or not, and there's only a small chance I will, this is important."
Jan, who has never been married and has no children, said he has lost friends over 2012.
"All the people I've ever told about this have declared me crazy," he said. "It makes people feel uncomfortable. Now I just keep it to myself."
Geryl said he found comfort in sharing his knowledge with others. Since "discovering" what the future holds, he has written three books on 2012 and maintains a Web site on the subject.
When asked what would happen if December 2012 were to come and go without the earthquakes and tsunamis of his predictions, Geryl fell silent.
"I don't really contemplate that possibility," he said. "[My predictions] are so spectacular, they can't possibly be wrong."
