alarming story on Yahoo news yesterday that got lost in the Iowa rush. The New Years day 4.0 earthquake in Ohio appears to not have been a natural seismic event but rather something potentially caused by a side effect of the controversial practice of "fracking".
CBS News did a report on this as well which you can watch here. It's not conclusive but certainly alarming that this method of disposing water waste from fracking could be setting off fault lines. So if the world does actually end in 2012, humans may be the direct cause of it.
