I thought I would start my actual research and try to establish a baseline that can be good to have in my future blogging. So my simple question was: How many people are we today? Answer: We are (roughly) 7,1 billion people sharing 1 Earth (May 2013, according to Worldometers web site, http://www.worldometers.info/world-population/ ).
Some historical perspective: We were about 1 billion people in the early 19th century, so in the last 200 years or so, we have gone from approximately 1 billion people to 7 billion people. I didn’t know that before…
Let’s look into the future! According to Worldometers, the population is still increasing but the rate that it’s increasing with has decreased since the late 1960s. Confusing? Well, it means that the population still grows, but not as fast as before. Some estimates of future population from the same web site:
- 2020: 7,7 billion
- 2050: 9,2 billion
- 2100: 10 billion (and Worldometers cite United Nations projections that say that the population will stabilize there. But maybe this is oversimplifying the projections. According to Wikipedia (search for World population) the UN 2010 highest projections suggest that we could be 16 billion and the lowest say that we could be 6 billion by 2100.)
