Thomas Malthus (1700s) researched the human population growth and tried to predict the future about mankind survival on earth. He said that the population growth is geometric, so if we plot a graph of the number of people through time, we will see exponential growth. The big question is: is it going to grow forever? How does the graph looks in the far future? The malthusian theory is that in a specific stage, the population cannot grow anymore, as several factors will limit this grow, like lack of food for everyone, epidemies, wars. The outcome of reaching this point where there is no more food for everyone is catastrophe. However, when we look at what happens today, mankind is flourishing. No catastrophe yet. Malthus was wrong with his prediction, as he didn’t know how big will be the progress of mankind is so many areas, like agriculture, technology, production, medicine, social, etc… This progress helped mankind to populate earth more and more without delays. Therefore the more reasonable graph to predict the future population growth, would be some kind of a slow down in the growth of population, which eventually follows the limitation of earth resources (not only food, but more factors which limit the population growth in the future, like natural resources, global warming?).
