Why do humans have such a yearning to see ourselves killed off only to save ourselves at the last minute? "Unless action is taken now," as the study claims.
It would be interesting if anyone ever actually acted on studies like this one. Until then, yes, I guess the disasters will just go on piling up.
However, I have fixed the Mayan calendar problem: It's the end of the 13th Baktun, which started in 1618. So, no more Mayan problem.
