Optimum population refers to the size of a population that produces the best results according to chosen end targets. One text from 1926 presented a single end target as being "...the largest per capital income of consumers' goods possible under the given conditions". Other potential end targets in favour of lower levels of population are cited, including: long term sustainability, efficient operation of democracy, the preservation of personal freedom and the preservation of biodiversity while potential end targets in favour of higher levels of population are cited, including the abilities: to preserve and foster cultural diversity, to stimulate intellectual, artistic, and technological creativity and to facilitate social infrastructure. ==Overview== Regarding the human population, end-targets for an optimum population include ecological sustainability, economic output〔On the Concept of Optimum Population'' P. S. Dasgupta The Review of Economic Studies Vol. 36, No. 3 (Jul., 1969), pp. 295-318 (article consists of 24 pages) Published by: Oxford University Press Stable URL: http://www.jstor.org/stable/2296429〕 and philosophical or ethical ends-in-themselves. Some commentators disagree with the concept of "optimum population", believing that the human population will always, in the long-term, be able to adapt to the requirements of a larger population. Any conception of an optimum population level must lie between a minimum viable population of the human species and the maximum level of population that can be sustained by the carrying capacity of the planet Earth. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Optimum population」の詳細全文を読む スポンサード リンク
