Q&A: Will people naturally select themselves?

People have been concerned that humans might be the cause of their own extinction.  It has serious merit, considering the mass amounts of nuclear weapons in the world and the growing number of nuclear armed states in the world.  Humans have gotten to the point where our intelligence surpasses our wisdom on controlling weapons of mass destruction.  Humans have been able to control themselves when they developed chemical weapons and thus far have been able to control the use of nuclear weapons.  It is possible that a rouge, irrational state gets control of a nuclear weapon or weapons and sets off a violent chain of events.  It is even possible that humans will develop and master the use of biological weapons which could be a even graver threat to humanity’s survival than nuclear or chemical weapons have ever been.  I gave humanity the benefit of the doubt that they won’t kill themselves, just as they had done before.  Hopefully the next generation of rulers won’t be bothered with the small short-sightedness and prejudices that lead to the deployment of huge amounts of weapons of mass destruction.
