Last question is about money.
Has the proportion of the world population that are desperately poor in extreme poverty during the last 20 years, has that doubled?
Has the proportion remained the same or has it halved?
Thank you.
So the last question, you were right.
The proportion of people in extreme poverty has halved over the last 20 years.
And the number of children in the world, you were wrong.
There's 2 billion children and it's not foreseen to be more children because they will indeed increase in Africa, but the number of children are decreasing in Europe and in Asia.
9 billion by mid-century, by end-century 11 billion.
But that is because of the fill-up effect.
We already now have 4 billion below age 30.
If they grow up and they have one child each, each couple two children on average, then you will have...
Four billions between 30 and 60 and four billions below.
Then you have eight.
And then you have the two older groups with two billions.
That's 10 billions.
That's where we will end up.
Perhaps 11 if we add one billion for longer life.
The breaking distance of a population growth is 70 years.
Today, there is about 2.4 children per woman in the world.
