Visual pollution refers to impacts that impair one's ability to enjoy a vista and includes billboards, trash, buildings, and other forms that create negative changes to the environment. It disturbs people visually and adds clutter. Billboards specifically are alleged to be distracting for drivers and promote overconsumption, while also clearing trees and intruding on landscapes per complaints from groups like Scenic America. Advertising is said to shape social behaviors and contribute negatively to culture by promoting products as solutions to incompleteness.
