<snip> Is it also possible that, with the proper application of innovation/technology, our planet could actually support a population of 100 billion or more?
Back in the '70s as I remember, R. Buckminster Fuller and students made a model of the earth with population, food, energy, resources, etc. mapped out on it. With it he showed where (with total co-operation between nations) every man, woman, and child on earth at that time could have a home, clothing, shelter, and the energy, food and clean water required to maintain the human population. Certain areas away from the coast had a slight deficit in protein, and there may have been other minor needs totally unfulfilled.
One of the requirements of the model was a grid system that circled the globe. In this manner, high energy need times (morning and evening) would circle the globe hourly (think time zones) while the low energy times could supply the additional energy needed. It fairly meant the dropping of borders. If the model was correct it appears to have been possible to provide all of humanity with it's needs with the technology and populations of the 70's.
Mark Victor Hansen (Chicken Soup for the Soul) claims to have been one of his students during the time the model was created.
So the problem (at that time) doesn't seem to have been one of a lack of resources or of to many people, but of humanities inability to co-operate. Required would have been a decrease in the living standards (at least temporarily) of the industrialized nations to bring the developing populations up to a minimal par for survival. This would imply if the population growth began to strain the sustainability of the system, a cap would be needed on the standard of living for all.
This brings to light the problem. What nations of people would be willing to take a decrease or have a cap placed on their standards of living for the sake of the rest of humanity??? Does this boil the problem down to one of a cultural/belief system? A system of identity and belief called Nationalism? Or are we just greedy monkeys who like shiny things, social status and don't like to share?
I stop here as I don't care to process this any further.
