"If, for the sake of illustration, the fertility of countries is kept constant at 1995-2000 levels, the world population soars to 244 billion by 2150 and 134 trillion in 2300 , a definitely impossible outcome. All of this increase occurs in the less developed regions, whose population rises from 4.9 billion today to 134 trillion in 2300. In sharp contrast, the population of the more developed regions declines from 1.2 billion in 2000 to 0.6 billion in 2300 were its fertility to remain constant at current levels. Among the less developed regions, Africa, with its very high current fertility levels, grows most rapidly, passing from 0.8 billion in 2000 to 115 trillion in 2300 in the illustrative constant-fertility scenario." http://www.un.org/esa/population/publications/longrange2/Long_range_report.pdf http://www.worldmapper.org/posters/worldmapper_map12_ver5.pdf If this unlikely scenario somehow came to pass (just use your imagination), it would mean that Europeans wou...
