Researchers unveiled staggering new population preductions on Friday. According to the Harvard School of Public Health, the global population is expected to top 9 billion by 2050. Sometime this year, the world's population should hit 7 billion. Researchers said by 2100, there could be 10 billion people on the planet.
But scientists said that the population increase will be quite lopsided. In developed countries such as Germany and Japan, populations are expected to stay flat or even decline. As a result, those societies could face major economic crises because there will be fewer young adults to care for the elderly.
Conversely, growth in developing countries is expected to boil over. According to the figures, in Africa, the population could grow 1.1 billion, representing nearly 49 percent of the projected growth by 2050.
