UN 'concerned' by world population growth trends
BBC - UK
The UN Population Division have produced six projections of potential future population change based on different changes to fertility level and other factors. In the medium scenario, world population peaks at 9.4 billion in 2070 and then starts to decline. However for this to happen, fertility needs to decline significantly in most developing countries. In recent years, there has been widespread acceptance of the medium scenario as almost a certainty. However Hania Zlotnik, the Director of the UN Population Division says there is "no guarantee that this scenario will become a reality because high-fertility countries may not reduce their fertility fast enough and countries with intermediate fertility levels may see them stagnate above replacement level".…(3 February 2011)
