Which of the following is an example of visual pollution?

Visual pollution (also called aesthetic pollution) refers to anything that negatively affects the visual appearance of an environment, making it unpleasant or unattractive to look at. Litter scattered across public parks is a clear example because it degrades the natural beauty and aesthetic quality of an outdoor space, creating an eyesore for visitors.

The other options represent different types of environmental pollution:

• High-pitched sounds from traffic horns are an example of noise pollution (or sound pollution), which affects the auditory environment.
• Oil leakage into rivers is an example of water pollution, which contaminates aquatic ecosystems and water sources.
• Excessive carbon emissions from factories are an example of air pollution, which degrades air quality and contributes to respiratory problems and climate change.

Visual pollution includes litter, graffiti, abandoned buildings, poorly placed billboards, and uncontrolled dumping. The key distinction is that visual pollution is identified by its impact on what people see in their environment, rather than what they hear, breathe, or drink.
