end of earth: 2012?

Tweet

i have read a site which named as "web bot". and as my eyes go everywhere around the site, all i can see is that there will be a "doomsday" (they call it) when the time is up for the eaRTH TO SURVIVE. my question is: do you believe that 2012 will be the end of the world?? are we already realizing the signs that if we further go to 2012 "WE" won't be able to survive??
