One of the most important and deadly problems the world faces is failing power grids.  we have become dependant on referigeration on transportation for our food supplies.  If the power were to go out for two months many people would starve to death . Our Power Grids are ridiculously vulnerable.  A strong Eltro Magnetic Pulse from the Sun or a nuclear bomb exploded in the upper atmosphere would take out our power stations.

Supermarket shelves would empty within 48 hours, leaving people to fend for themselves.  We caught a frightening glimpse of how this scenario would look recently in Venezuela.
