Never has the planet had as many people as now and the more people there are the more competition there is for resources. More countries seek nuclear devices than ever before and with advancements in technology this is a much easier process than anytime before. Biological and chemical weapons are also much easier to manufacture because of leaps of technology in regards to computers. Oil markets are much tighter because of the countries of China and India and their increasing need of energy to fuel their booming economies, and new finds of oil fields cannot keep up with the demand. The debacle of the world economies needs no introduction.
