In all my reading about sustainability and peak oil I often find that overpopulation is also one of the causes (or scapegoats) commonly mentioned. It is true that there is more people than ever and that means we are having more babies than ever, even when many cultures are limiting the number of their children to 1 or 2. In fact, the world average is 2.65, while in the 1950's it was 5. People also live longer though, so even though we have about 6.7 billion people, by 2050 there is projected to be 11 billion.
