WebApr 6, 2016 · The formula used to calculate logistic growth adds the carrying capacity as a moderating force in the growth rate. The expression “ K – N ” is equal to the number of individuals that may be added to a population at a given time, and “ K – N ” divided by “ K ” is the fraction of the carrying capacity available for further growth. WebDespite its seeming scientific precision, the claim is old, not new – the latest iteration of the longstanding assertion that our population and consumption might soon exceed the Earth’s fixed ‘carrying capacity’. The concept, tellingly, owes its origin to 19th-century shipping, referring to the payload capacities of steam ships.
