Using system dynamics software or a computer program, model the predator-prey example, including crop consumption discussed in the Historical
Note about the Chinese Cultural Revolution.
Historical Note:
During the Cultural Revolution in China (1958–1960),
Chairman Mao Zedong decreed that all sparrows be killed because
they ate too much of the crops and they seemed to be only for pleasure anyway. With reduction in its main predator, the insect population increased dramatically. The insects destroyed much more of
the crops than the birds ever did. Consequently, the Chinese reversed the decision that caused the imbalance (PBS 2002).
