To Pollute or Not to Pollute: A Common Pool Dilemma Game

In this activity, participants examine the thought processes they use to make decisions about the environment. They will be introduced to common pool resources or resources which are difficult to exclude people from using (like the lake in this game). Participants will also learn about free riders- people or groups that consume more than their fair share of a resource or shoulder less than their fair share of the costs of the shared resource.
