OK don't get this. BBC reports that the UN warns of a population surge. A recent UN report says that they expect the population of Earth to reach 9 billion in 300 years time. 300 years! By then we'll be across the solar system and probably across the stars. And we'll probbaly be post-human anyway. Seems a very pointless exercise. More interestingly they say that if fertility rates were to stay at current levels (rather than reducing to 2 children per female) then the population would be 134 trillion(!) in 30 years.
