This week the world’s population will hit 7 billion people. Actually it may have already occurred, or may occur in the next few months, but more on that later.
Put simply 7 billion mouths are a lot to feed, and given some 13 million of us are currently facing starvation in the famine devastating the Horn of Africa it is a daunting prospect. Another 1 billion of we people live in hunger and poverty every day.

And to make matters more complicated our population is projected to grow by another 2 billion people in the next forty years.
To put some perspective to that, in 1900 the world’s population was an estimated 1.6 billion. In 2000 it was 6 billion. It has taken just over a decade to add the next billion souls.
Which raises a couple of questions:
- Are the estimates of an extra 2 billion people over the next forty years right (after all that is adding to our population at half the rate of the past decade)?
- And how exactly will we feed these people, given most of the new additions will be in developing countries?
