In recent centuries, the world's population has risen dramatically to more than seven billion people. Between 1900 and 2000, the increase was three times higher than in all of human history before - an increase of 1,5 to 6,1 billion people in just 100 years. But even here there are positive developments to note. Thus, the annual growth rate (graph) of 2,1 percent has already fallen to 1,2 percent (2015). The forecasts speak of a significant drop to 0,1 percent until the year 2100. For the last half century, we live in a world where population growth is declining. Even so, the global population, even though it is weaker, will see its 2100 billion population shrinking, after which the world's population is likely to decline.
