What could be an effect of not clearing dust and flying materials in urban areas?

The correct answer identifies air quality deterioration as a significant effect of failing to clear dust and flying materials in urban areas. Urban environments are often congested with traffic, industrial activities, and construction work, all of which contribute to the accumulation of dust and airborne particles. If these materials are not regularly cleared, they can lead to a buildup of pollutants in the air.

Poor air quality can have several negative health effects on the community, including respiratory issues, allergies, and long-term health conditions such as asthma or other lung diseases. Additionally, dust accumulation can contribute to visibility issues and can have detrimental effects on the environment, such as harming vegetation and wildlife.

In contrast, enhanced community health, increased property value, and better sanitation practices are unlikely outcomes of neglecting to manage dust and airborne materials. Instead of improving these areas, an increase in dust and related pollution typically has the opposite effect, highlighting the importance of maintaining air quality through effective sanitation measures.
