My initial response to the graphic below was “Right On!”  However, on reflection, there is a huge caveat that must be appended to it.

2500 years ago, mankind’s greatest threats were communicable disease and large predatory animals.  Those were the conditions mankind lived under.  NOW, we no longer worry about many of the diseases that once ravaged continents, and most large predators are on the brink of endangered status or extinction.  The greatest threats humanity faces today are ENTIRELY of mankind’s own creation.  Poisons, toxins, weapons of war, surveillance states . . . welcome to the Brave New World.
