A very nice and well written article. You indeed clarified a lot of issues that have lingered for long...
In summary we cant exceed the worlds population cap, but what of the population effect on the available resources?
A hungry world with people starving, would that be nice?
Do you think reduction in population size would make more resources available? I don't think so. Presently, A large percentage of the world's wealth is in the hand of few. Millions of humans die daily from hunger while some humans have food their tenth generation cannot finish. The problem of the world is not inadequate resources but hoarding of resources. A reduction in population size would not reverse the trend.
