I think this coming famine is self-engineered, like most famines.
There is no reason for the price of oil to be that high outside of human subjective perceptions. There is no reason for there to be a famine outside of human-initiated choices in the marketplace.
Like most declining societies, what happens out there just reflects what is happening up inside the minds of the people living in that society. Most citizens of the West are just not the people their ancestors were.
"The average age of the world's greatest civilizations has been two hundred years. These nations have progressed through this sequence: From bondage to spiritual faith; from spiritual faith to great courage; from courage to liberty; from liberty to abundance; from abundance to selfishness; from selfishness to complacency; from complacence to apathy; from apathy to dependence; from dependency back again into bondage."
