Around the world, the population is expected to hit seven billion this year according to the UN. That is more than twice the number of people that lived on the earth just 50 years ago! The population is expected to exceed nine billion by 2050 and 10 billion by 2100 (few of us will be around). For the next forty years, an estimated 2.3 billion more people will be added with 97% of the growth will be in developing regions. In Africa alone, the population is expected to grow 1.1 billion, or 49% of the global projected growth, by 2050. But in some developed countries like Japan and Germany, the growth rate is expected to stay flat or even decline. In the coming decades, these countries could face a crisis as society fails to produce enough adults to care for the elderly.
