Of particular worry, decreasing population entails decreasing gene pool (as I understand it). Thus, with a lack of sufficient genetic diversity in a small population, the species enters a mutation-motivated extinction vortex [1]. Biology is a very existing field from the standpoint of mathematical formalism, which is lacking relative to the much older field of Physics. In this regard, I'm reminded of how the overly simple math of Mendelian inheritance motivated the bad policy of eugenics [2]. I welcome any proper Biologists to correct my remarks. I have but passing interest!
