Urban gardens clean city air naturally

Urban gardens are powerful natural filters, significantly improving air quality in crowded cities. Plants absorb harmful pollutants like carbon dioxide and release oxygen through photosynthesis, directly countering emissions from vehicles and industries. Trees and shrubs trap particulate matter such as dust and soot, preventing it from entering our lungs. The U.S. Forest Service estimates urban trees remove 711,000 tons of air pollution annually, including smog-forming gases.
