My point was that population growth (ignoring immigration) is
approximately zero in the most developed nations. It's exponential
growth with an exponent of 1, if you want to put it that way. In other
words: I find the idea that humans will continue to breed and increase
the population ad-infinitum, outstripping all available resources,
somewhat unlikely.
