It might be said that the human race is incapable of withstanding the drastic changes that are taking place in today’s world. For those changes have been so terrible, so far-reaching and, above all, so swift that they make those that caused the disappearance of the dinosaurs pale into insignificance. Man has not had time to adopt to the sudden and powerful changes that his technology and society have produced around him, and it might safely be said that many of today’s illnesses are the means used by the cosmos to eliminate this proud human race. Man is the only animal to have created his own environment. Ironically, he is also the only one to have thus created his own means of self-destruction.
