We live in a world of relentless change. Huge migrations of people to new mega-cities filling soaring skyscrapers and vast slums, ravenous appetites for fuel and food, unpredictable climate change... and all this in a world where the population is still growing. Should we be worried, should we be scared, and how to make sense of it all?
Seven billion people now live on this planet of ours. Isn't it beautiful? When some people think about the world and its future they panic, others prefer not to think about it at all, bit in this documentary Professor Hans Rosling will show you how things really are.
Rosling is statistician and he'll show you the world in a new way. He'll tell you how world's population is changing and what today's data tell us about the future of the world we live in. We undeniably face huge challenges, but the good news is that the future may not be quite as gloom and that mankind already is doing better than many of you think.
Many people think population growth is out of control, some even talk about the population bomb, but are they right? Most of the population growth in recent years has been in Asian countries, like in Bangladesh, where the population has tripled during Rosling's lifetime from 50 to more than a 150 million. It's now one of the most densely populated countries in the world.
However people in Bangladesh, whether in the city or the countryside, are intensely concerned about the size of families. There is a cultural shift away from big families and there is actual success in reducing the fertility rate, which is the number of babies born per woman. In just 40 years Bangladesh has gone from 7 to 2.2 children per family. But is it only in Bangladesh? According to the Rosling's stats the trend is worldwide. In 1963, the average number of babies born per woman in the world was 5... and today the average is 2.5.
