In the next forty years, the earth will need to accommodate nearly 3 billion more people. That's more than the current population of the whole of Europe, 1__________________________, North and South America combined.

How can we be so sure of this prediction? Well, we know that there are more than a billion teenagers alive today and most of those teenagers will have children of their own and live 2__________________________________ grandparents and that's all that needs to happen for there to be 9 billion humans alive in 2050.  It's not people having huge families.  It's just a lot of people doing 3_____________________________.

We also have a good idea of where these additional people will live.  There are likely to be 10 million more people in Britain.  A hundred million more in the United States of America.  4______________________________ to become the most populous country in the world.

  The population of some countries will shrink: Japan, Russia, Germany and much of Eastern Europe.  The places that will experience the most rapid growth are also the least developed 5_____________________ Afghanistan's population will double.  Most of sub-Saharan Africa will double.  Niger's population is predicted to more than triple.  I think everyone living through the next fifty years is going to be 6__________________________changes wherever they are.

    For most of human existence, our population size 7_______________________ by nature just as it is for other animals. If there's plenty of water, food and materials for shelter, a population will thrive. But when disease, famine or drought strike, life 8_________________________.

The history of humanity is one of overcoming these environmental limits but it took us a very long time to achieve.

 It's a very boring picture. But from about the year 1800 onwards, you have a major increase - a very large increase - in the world's population from about 1 billion up to 7 billion today.
