Prior to the Agrarian Revolution, people then led nomadic lives, going around searching and gathering food and hunting wild animals. This is because at that time, they could obtain food easily from their surroundings and they were satisfied with their way of life. This was because people of that time lived in small groups, from 25 to 40 people. This method of survival is met easily with small groups, as the amount of food to be gathered is also not very large. Even though if the group increases to a number whereby they could not handle, they would break up into even smaller groups and continue with this kind of way of life. However, on a global scale, as all the small groups became bigger and split into smaller groups, and these smaller groups grew bigger too and split into smaller groups again, the total number of so-called small groups increase, as well as the number of people in the group. Hence, the total population was slowly increasing. Moreover, their kind of way of life was only suitable and efficient only with the abundance of land. Taking the situation from a mathematical perspective,
Amount of food µ Land area
Since amount of land does not change, thus the amount of food collected is fixed.
Amount of food collected
Amount of food per person = ---------------------------------------
Number of people in the group
As time passes, the number of people in the group would increase. From the equation, we can see that the amount of food one receives would decrease with time. Considering the fact that the group would split up into smaller groups if the number of people were too big to handle, on the global perspective, the population of the world grew rapidly.
Amount of land per group = ----------------------------
Number of groups
From the above equation, the amount of land available for each of these groups would decline without fail since the splitting of groups would result in the increase in number of groups, and when small groups are formed, people would feed that it is alright to increase the size of their own group, in a way for defence purposes as the saying goes "Safety in numbers". As a result of their narrow perspective, they repeated the mistake over and over again. This led to the formation of a vicious cycle. The people encountered the heavy burden of their own group facing famine. As a result, after serious considerations and thoughts, a new way of life, by agriculture was spearheaded, which ignited the Agrarian Revolution.Back to Top
