EXCERPT...
I once asked the famous astronomer Carl Sagan who was a friend of mine, if he thought there was other life in the universe, and he paused and thought for some minutes before he said no, and when asked why he said if any other life forms had reached our stage of evolution they would have destroyed themselves.
It seems that we need to surmount a rapid evolutionary hurdle before the human race wakes up and decides to stop killing each other, to alter the way we live, to value the wonder of nature and evolution and to decide once and for all that we are indeed capable of such actions and that we will do it.

I don't agree with Sagan here, but I do share his analysis of mankind.
