human race heading for self-destruction ?

Into Eternity is a documentary about nuclear waste in Finland I saw a few weeks ago that really got me thinking… since then even more hell has broken loose in various parts of our world.. the way the human race are acting with all their conflicts, greed, religious disagreements, capitalism, hunger, war and hate we´ll  soon be heading for a self destruction – wondering if we´ll all be better to each other after a few ice-ages??
