But population doesn't follow rationality, it follows the Logistic function: http://en.wikipedia.org/wiki/Logistic_function http://en.wikipedia.org/wiki/Logistic_function The Logistic function's left-hand side looks as flat as it does because there are too few organisms to support a larger growth rate. The Logistic function's right-hand side looks as flat as it does because there are too many starving organisms to support a larger growth rate. Welcome to natural selection. :)
