Clean air becomes polluted because

Question

Quizplus · Accepted Answer

Air pollution occurs because there is no ownership or property rights associated with the air. Therefore, no one is held responsible for polluting the air, and no one has an incentive to maintain clean air. If clean air were a private good, it would be owned by someone, who could then charge a price for its use and maintain it. If it were a club good, it would be owned by a group of people who agree to maintain it and regulate its use. However, because it is a public good, it is subject to "the tragedy of the commons," where individuals each act in their own self-interest and overuse or pollute the resource.
