Marginalized communities are often more vulnerable to poor air quality primarily because they typically have less access to healthcare and other critical resources. This limited access means that individuals in these communities may not receive timely medical attention for respiratory issues or other health problems related to air pollution. Furthermore, these communities frequently lack the financial means to mitigate their exposure to pollutants, such as by relocating or investing in air filtration systems.

Additionally, marginalized populations are often situated near industrial sites or transportation corridors that are significant sources of pollution. This proximity amplifies their exposure to harmful air contaminants while their reduced access to information and advocacy can diminish their ability to address these environmental issues. Consequently, when air quality declines, the health impacts are disproportionately felt in these communities because they are left with fewer tools and resources to combat the consequences of poor air quality.
