In the present paper, the author builds simple ¡°mind sized¡± world models designed to convey to readers the main qualitative features of world modeling. These models turn out to provide results comparable to real-world historical cases and are similar to those generated by the more complex ¡°World3¡± model used for the ¡°Limits to Growth¡± study. %K Limits to Growth %K System Dynamics %K world modeling %U http://www.mdpi.com/2071-1050/5/3/896
