It is my position that we as a species are negligently out of balance and thus the reason for the cancer, I.e., wars, famines, economic calamities, uprisings whether they be caused by contrived conspiracies or natural progression. I tend to view it as growing pains, transitional manifestations of a living organism. Again I will be the first to tell you that I am not a social engineer, nor a scientist, but in my defense I do posses common sense which in these days appears to be no longer common nor make much sense.
Understand that we live in an ordered world, where there are cycles, systems of natural law that exist; that attribute to the establishment of balance & harmony on a consistent basis. It would seem to reason that man would follow in this model of harmony.
