8.7.5: Air Quality
Air pollution also tends to be higher and is associated with higher rates of childhood asthma in poorer communities. Due to historic redlining practices and discriminatory residential zoning, communities of color are more likely to be near air pollution sources like factories or hazardous waste sites ( Environmental Conditions - Healthy People 2030 , n.d.). City design and lack of investment in poorer urban communities means they tend to have higher automobile traffic and fewer trees planted - both of which affect air quality and ambient temperature. See Fig. \(\PageIndex{1}\) below for more sources of air pollution.
