Negative externalities : Pollution :: Positive externalities : ?

Negative externalities, like pollution, occur when a company's actions harm others without compensating them. In contrast, positive externalities benefit others without the provider receiving payment. A good example of a positive externality is a well-kept garden in a neighborhood. When someone invests time and money into their garden, the surrounding community enjoys beautiful scenery and increased property values without having to pay for it. So, just as pollution negatively affects people nearby, a beautiful garden positively impacts everyone around it.
