The specter of hunger, famine, and malnutrition have been the legacy of
mankind since recorded time. Overpopulation in the old world in the late
nineteenth century resulting in depletion of available resources coupled
with famine and pestilence led to a series of massive emigrations from the
European and Asian continents to the Americas, to the African subconti￾nent, and to Australia. These emigrants brought with them newly devel￾oped technologies of the European industrialized nations and the time￾honored agricultural methods of the Orient. The skills and knowledge of
these emigrants helped develop the virgin resources of the newly discov￾ered and undeveloped continents. As we enter the twenty-first century the
regular cycles of overpopulation, famine, and political instability are again
with us. However, this time there are no new continents left to be discov￾ered and no new colonies left to be developed to feed their respective
mother countries. Every available inhabitable room in our Spaceship Earth
has been claimed and populated and is rapidly reaching its capacity. The
only real option left to cope with this dilemma is to become better stewards
of our renewable and nonrenewable resources.
