Mankind

Its my constant crib that the problem of the universe is yours truly - the human being. Imagine a world without that one species - can guarantee there would be now problems at all - No pollution, no population growth, no resource crunch, no inflation, employment, unemployment, nukes, global warming, absolutely no issues at all. It would have been perfect. We human beings are the only type that causes problems and then take pride in solving them. Hurrah.
