Study this definition of public good.

"Public Good
A public good is a product that one individual can consume without reducing its availability to another individual, and from which no one is excluded. Economists refer to public goods as "nonrivalrous" and "nonexcludable." National defense, sewer systems, public parks and other basic societal goods can all be considered public goods."
