Beyond 2050 the world population may start to decrease if women across the world will have, on average, less than 2 children. But that decrease will be slow.
The number of children is not growing any longer in the world. We are still debating peak oil, but we have definitely reached peak child.
If your economy grows [by] 4 percent, you ought to reduce child mortality 4 percent.
You don't have to get rich to have [fewer] children. It has happened across the world.
I meet so many that think population growth is a major problem in regard to climate change. But the number of children born per year in the world has stopped growing since 1990. The total number of children below 15 years of age in the world are now relatively stable around 2 billion.
