5Question prompt in the survey included the following definition of “tragedy of the commons”: Garrett Hardin’s classic dilemma, the “tragedy of the commons,” arises when multiple individuals, acting solely out of their own self-interest, ultimately exhaust a limited shared resource despite the fact that it is in no one’s long-term interest for this to happen. A well-known example of this situation involves a group of individuals grazing cattle on a tract of common land. Each individual will seek to maximize his/her gains, and each individual will benefit from grazing additional cattle on the land.
This continued increased use will eventually deplete or even destroy the utility of the common land, and these negative effects will be felt by everyone. Since the negative effects of grazing additional cattle are shared by the group, but the benefits of additional cattle reside with the individual, each rational individual will continue to graze additional cattle despite the ultimate detriment to the group.
