True or False: Ozone at ground level is considered a harmful pollutant.

Ground-level ozone is indeed considered a harmful pollutant. Unlike the ozone found in the upper atmosphere, which protects us from harmful ultraviolet radiation, ground-level ozone forms when pollutants emitted by vehicles, industrial facilities, and other sources react in the presence of sunlight. This ground-level ozone poses significant health risks, particularly to vulnerable populations such as children, the elderly, and individuals with respiratory issues. It can cause or exacerbate conditions like asthma and other lung diseases, while also harming crops and other vegetation.

The option stating that ground-level ozone is a harmful pollutant is correct and aligns with regulations and classifications set by environmental agencies. Understanding the effects of ground-level ozone is crucial for awareness regarding air quality and public health.
