I think the only reason people wonder is because it does seem like world events are reaching a critical melt down. Major natural disasters happen more frequently. Earthquakes (Haiti, Japan, Brazil to name a few) hurricanes (Katrina) and human disasters (Gulf Oil Spill, Japanese nuclear plant). Financial melt down across the globe, (US, Greece again, Italy) and political corruption (the whole world).
Personally, I think everything is fine.
