Worry warriors need a reality check

 The unecessary negative effect of misapplied worry by non scientists and a desperate media is something readers should resist. Ignorance driven stuff  by the noisy and nosy reduces our children's faith in science and technology and therefore our ability to manage risk and build real resilience .

Its wrong too when people who are not practical  try to speak for those that are .A sound knowledge of chemistry and geology will limit the extent to which you worry about real disasters and work towards preventing another.
