And once the population hits zero, there is no bouncing back. For your body, that species is now extinct. My worry is that some of these critical residential organisms — what I consider “contingency” species — may disappear altogether.

Why might it matter? Those puny species may not be so inconsequential. Microbes multiply. Any small population of, say, 50 cells can explode into a billion or more in one week.
