What strategies can communities implement to improve local air quality?

Enhancing public transport and increasing green spaces are effective strategies for communities to improve local air quality. By investing in public transport systems, communities can reduce the number of private vehicles on the roads. Fewer cars lead to decreased emissions of pollutants and particulate matter that contribute to poor air quality. Moreover, enhancing public transport makes it a more attractive option for residents, encouraging them to use it for their daily commutes, which further helps in reducing traffic congestion and the associated emissions.

Increasing green spaces, such as parks and community gardens, can also play a crucial role in air quality improvement. Plants and trees absorb carbon dioxide and other pollutants, releasing oxygen in the process. They act as natural air filters, reducing levels of harmful substances in the air. Additionally, green spaces can help mitigate the urban heat island effect, which can cause higher air temperatures and exacerbate air quality issues.

In contrast, increasing litter disposal areas while reducing green spaces, encouraging more private vehicle use, and limiting urban development do not support effective air quality improvement. The former would not address air pollution directly, while promoting private vehicle use would lead to more emissions. Limiting urban development, while it may have some benefits, could also hinder growth and the potential for improving public transport and green infrastructure
