PETER BERGEL: On the surface things look pretty grim. The chances for any kind of meaningful world peace seem remote. The environment is terribly degraded and seems to be retaliating with global climate change †probably the worst crisis the human race has ever confronted. The economic system is in the toilet and may not recover. People are hurting everywhere  from poverty, disease, war, racism, renewed threats to liberty and despair. And yet… amazing currents are flowing all over the planet, washing in a harvest of hope that so far has not captured the notice of the mainstream media.
