In many respects, the figures for Africa represent the most disconcerting aspect of the United Nations report on population growth. Africa’s population today stands at 1 billion. According to the U.N., that number will increase to 2.2 billion by 2050 and 3.6 billion by 2100. It took humankind more than 50,000 years to reach 1 billion, and now Africa alone will be adding more than that number in just four decades… No other region will come close to having such a rapid rate of population growth in the coming decades (1.9 percent per year). Africa’s billion only represents 15 percent of world population today, but Africa will account for 49 percent of global population growth over the next four decades.
