Not sure if you've seen this series: http://www.youtube.com/watch?v=F-QA2rkpBSY (despite looking/sounding boring at the start, stick with it; it's really captivating and interesting), but it is amazing just how much 'small' growth (even 2-3% p/a) can cause things to double in much less time than you'd imagine.
Or if you haven't got the time to watch the whole thing (is close to an hour all in all), this touches on a couple of the topics the video covers: http://www.worldpopulationbalance.org/exponential-growth-tut... (naturally doubling every minute is on a much faster scale to the Human population!)
