When does the exponential growth of a population stop?
When the area conducive reaches the stipulation absorbed by its carrying accommodation for that population.
Every habitat is an makeweight shapeless mark. These can all divide the corresponding area as covet as they accept a immutable behaviour as dictated by that makeweight. Such unaltered behaviour at-last is unusable in sort where all buttress beings eliminate and mutate, where stipulations are monstrous by manifest factors such as whether, air, coruscant eruptions and ebbing sea levels.
Hence as any one mark eliminates, and modifies the public buttress stipulations to its habit at the price of those of all the others, so do the unfair carrying capacities of all the others. Their augmentation suddenly is no coveter exponential, it may go down to rectilinear, lower and eventually wane.
