SWITZERLAND, JULY 12 – It took thousands of years for the global population to hit 5 billion, which happened in 1987. Some 32 years later, we’re closing in on 8 billion.

This explosive growth concerns leaders at the United Nations, who created World Population Day in 1989 to raise awareness about the problems caused by overpopulation. The holiday is observed annually on July 11.The planet’s population today is 7.7 billion.

How mind-bogglingly huge is that number? If you started now and ticked off 7.7 billion seconds, you wouldn’t be done until the year 2263.And by 2050, the world is projected to add another 2 billion people.If we have issues with overpopulation now, just image the future impact on the planet. Here’s a closer look at some global population trends.

According to the UN, 27 countries or areas have seen their populations shrink by 1 percent or more since 2010. This drop is caused by sustained lower levels of fertility, most notably in countries like China amd Japan.In fact the global fertility rate fell from 3.2 births per woman in 1990 to 2.5 in 2019 and is projected to decline further. But these shrinkages are dwarfed by population booms in other regions. The population of sub-Saharan Africa, for example, is projected to double by 2050.
