Maybe a war, theres already a few wars happening right now, and its only building up with the middle east revolution. There could be another disaster on a larger scale, there has already been maybe 4 in 2011? from the top of my head.. brazil floods, australian floods, New Zealand earthqauke, and now Japan who got everything at once. There is certainly a buildup toward something. There has been a lot of death's already in 2011.
