"Overpopulation refers to when an organism’s numbers exceed the carrying capacity of its habitat."
I would love to see some hardcore numbers how many inhabitants our "habitat" can support in an sustainable way?
Our oil reserves won’t last much longer and within fifty years our petrol based lifestyle and food production will simply collapse, because the supply won’t last. At least it seems production rates already can’t keep up with demand.
But we all as a world community have to figure out how many people this planet can support - so we can plan and adjust. We will need to once again have to look seriously on family planing, productions numbers and available resources - but in a scientific way.
