Latest Sustainability reports
Now let us look at the latest and previous reports on sustainable human population at various standards of living and living practices and morals.
The latest that I am aware of, take into account the rapid lowering of planetary human population sustainability. This lowering is from long term depletion of soil, and groundwater, along with rapidly increasing pollution effects from various sources and for various very long terms.
What had been 1.5 to 2 billion at Euro levels (generally, clean and 2,500 cal. per person per day) in 1972, 80, and 92 studies has become between .5 and 1 billion at Euro levels now. At a very poor 1,400 CPPPD level, it is 3 billion. The levels have fallen in half in less than two decades.
The trend is for this to continue to 0 by 2100 unless very drastic changes in numbers of people, and GHG pollution are made, along with massive water use reduction devices and programs, and massive soil rebuilding/composting programs are initiated. The time for actual implementation is being used up rapidly in ineffective and too few efforts. The closer we get or more time that is wasted, means the necessary changes have to be greater and greater. A point of logistic impossibility is reached, and the necessary changes almost as abhorrent as the population crash itself. The fact that most of humanity is not educated or intelligent enough shows it is time for a speciation event, however with planetary biosphere eco-failure cascading, this would be less and less likely. The trend is toward the completion of an E.L.E., that on a geologic scale, we are in the middle, or actually toward the end of.......it is like the stopping distance needed for a car heading toward a cliff edge. The car needs a parachute, or fold out wings and tail.<rockon>
