The news you are about to read puts everything else in the category of "insignificant" by comparison. Concerned about the 2012 U.S. presidential election? Worried about GMOs? Fluoride? Vaccines?

None of that even matters if we don't solve the problem of Fukushima reactor No. 4, which is on the verge of a catastrophic failure that could unleash enough radiation to end human civilization on our planet.
