The United Nations' population division now says the world will reach 7 billion on Oct 31, 2011 (America's Census Bureau delays the date until Mar 2012). Once upon a time, the passing of population milestones might have been cause for celebration. Now it gives rise to jeremiads. For most people, the big questions about population are: can the world feed 9 billion mouths by 2050? Are so many people ruining the environment? And will those billions, living cheek-by-jowl, go to war more often? On all three counts, surprising as it seems, reducing population growth any more quickly than it is falling anyway may not make much difference. But the main impact comes from relative changes - the growth of one part of the population compared with another, for example, or shifts in the average age of the population - rather than the absolute number of people. Of these relative changes, falling fertility is most important.
