The number of individuals on Earth is constantly rising, a trend fueled by technological advancements, enhanced medical care, and readily available natural resources. Nevertheless, this ongoing population expansion carries the risk of culminating in a major catastrophe. This conclusion was reached by researchers at Flinders University. These experts assert that, given our present lifestyle pace, the world has already exhausted its capacity to supply humanity with essential materials.
For their calculations, the scientists utilized the ecological Ricker model. This mathematical approach enables the tracking of population fluctuations across numerous generations for any living species, taking into account inherent natural constraints. The resulting computations yielded two primary figures for our planet: its absolute maximum capacity and its sustainable carrying capacity.
The former figure denotes the utmost number of people possible if current trends persist. Under such a scenario, natural reserves would deplete even more rapidly, and the overall ecological situation would significantly deteriorate. The latter figure reflects the population level recorded during the period of the swiftest growth, specifically noted around 1929–1930. This value represents the population size that can subsist comfortably without causing harm to the natural environment.
