What's fascinating is the the Rat Utopia[0] experiment in overpopulation from the late 60's that Dr. John Calhoun ran.
As a result, more than fifty years ago, on tape, Dr. John Calhoun made some eerily accurate[1] extrapolations of where human population is going to be now, and how our TFR (total fertility rate) would collapse (which they basically are, particularly since Millennial & Gen Z generations).
