OPTIMUM LUDNOŚCIOWE JAKO REMEDIUM NA ZAGROŻENIA DEMOGRAFICZNE? KONFRONTACJA PERSPEKTYWY GLOBALNEJ I LOKALNEJ
POPULATION OPTIMUM AS A REMEDY FOR DEMOGRAPHIC THREATS? CONFRONTATION OF GLOBAL AND LOCAL PERSPECTIVES

Summary/Abstract: Studies on the threat of depopulation or overpopulation, as well as the searchfor a population optimum for the Earth, are almost without exception conducted inisolation. The first indicate that the population of certain areas should be increased forsocio-economic reasons. The second signal the need to drastically reduce the Earth'spopulation because it has exceeded its capacity. The third finally focus on the search foran answer about optimal population for the Earth, generally indicating a value muchlower than the current population of the planet. This paper juxtaposes the mainstreams of research on these three issues, in search of an answer to the question of theextent to which the population optimum is capable of ensuring the Earth's long-termstability in the context of the needs of ecological and geopolitical balance. It has beenproposed to come to terms with the irreversibility of demographic changesaccompanying social change, to appreciate the role of migration as a factor balancingand reconciling the demands of proponents of both extreme concepts.
