Keith,
      I admire your tenacity and occasionally the eloquence of your argument. However the very act of living is a case study of risk and the management of risk.
      Without a continuous search for new sources of oil the price would rise alarmingly and the knock on effects would be horrific.
As yet there is no substitute and the modern world requires abundant energy. I think recent events have demonstrated that the nuclear option
also has significant risk of a far higher magnitude than a periodic oil spill and can have a multi-generational impact.
      If all the treehuggers had to walk to find a tree then I suspect their protests would diminish to insignificance.
