Today, there’s just over 7 billion people across the world. Now, throw 4 billion more people in the mix by 2100. According to a new prediction, there’s an 80% chance of that happening over the next 90 years.
Where is this population growth expected to happen? In areas that still have low population density such as Africa. Birth rates in sub-Saharan Africa have not been falling as fast as predicted. Sub-Saharan Africa are the countries south of Algeria, Libya and Egypt.
