Air Pollution Sources: Factories, Vehicles, and Urban Emissions #3350272 (License: Personal Use)

This flat-design illustration highlights primary human-caused air pollution sources: industrial facilities with smokestacks (some marked with radiation symbols), fuel tanker trucks, high-rise buildings, and gasoline-powered cars-all releasing dense black and blue plumes. One cloud explicitly labels CO₂, emphasizing greenhouse gas contributions. The scene conveys the cumulative effect of urban and industrial activity on atmospheric quality.

Used on environmental education pages, climate change reports, or public health articles to visually summarize anthropogenic emission sources; matches user intent for understanding pollution origins or supporting policy advocacy.
