A public good is a good that is non-excludable, meaning that it is difficult or impossible to prevent someone from using it, and non-rivalrous, meaning that one person's use of the good does not diminish the amount available for others to use. Clean air resulting from laws reducing pollution is an example of a public good because everyone benefits from it and no one can be excluded from using it. The other choices are not public goods because they are either excludable or rivalrous.
