It's believed it wasn't until 1814 that mankind first reached a billion strong. When I was born that had reached 2.5-billion. This year our numbers swelled to 7-billion.
We had been told that we might actually reach 9-billion people by 2050 after which our numbers would begin to decline. Now the UN has rejigged its calculations to warn that we'll probably hit 10.1-billion by the end of the century. Its worst-case scenario would see that reaching 15.8-billion by 2100.
The projection has ''serious implications'' for the ability to provide food, water, energy, education and employment for millions of people in the poorest nations, said Hania Zlotnik, director of the population division of the UN Department of Economic and Social Affairs, which released the report yesterday.
''Much of this increase is projected to come from high-fertility countries, which comprise 39 countries in Africa, nine in Asia, six in Oceania and four in Latin America,'' the report said.
