““Last, but by no means least, the advance of technology has produced a human population that is far more helpless and dependent than any human population before, one that is unable to survive when exposed to the elements, or travel long distances on foot, make its own tools, construct its own shelter, clothe and feed itself without outside assistance, treat diseases with substances available from the environment, or teach its children to survive on their own … How will these people, who have been conditioned since birth to expect to be taken care of by a vast industrial machine, respond to suddenly being forced to rely on their own wits and physical strength to survive? How many of them will not even try and simply await a rescue that will never come?””
