Strengthening the Environmental Argument about Green Spaces

A recent environmental report asserted that cities with more green spaces experience lower levels of air pollution. In an effort to support this claim, the report referenced a study that included data from ten cities, noting that the three cities with the highest amount of public parks had significantly lower metrics for particulate matter in the air.

While the report suggests that increasing green spaces may lead to cleaner air, critics argue that the report does not account for other potential factors influencing air pollution levels. To strengthen the argument, further evidence is needed that directly connects the presence of green spaces to cleaner air outcomes.
