Household residents are affected by animal overpopulation because they are the ones who have to watch stray animals roam around and fear of getting bitten by a rabies-infested animal.
Businesses could potentially lose money over animals roaming around and getting into trashcans and whatnot. This is very unsanitary, especially for patrons dining at restaurants.
Citizens of the United States pay the government taxes to fix problems and care for people, so they must get rid of the problem.
Worldly, stray animals need somewhere to go; whether it an animal shelter or a home. Even Shanghai, China now limits the number of domestic animals a household is allowed to keep to prevent rabies.
Resources, goods and services, and finances are affected because we end up using our own money to get rid of the problem by providing animal shelters or even euthanizing some of the animals.
