Researchers performed a population-based study of 27,372 children who live in Metro Vancouver, Canada and found that natural green spaces (parks, gardens, lawns, etc.) promote early development by reducing nitrogen dioxide (NO2), a traffic-related pollutant. Nitrogen dioxide and noise exposure are harmful to children as they could lead to increased stress, sleep disruption and adverse effects to brain function. To measure the effects on children, researchers used teacher ratings from the total Early Development Instrument (EDI) as the primary outcome variable. To measure the green spaces near the residential areas, researchers used percent vegetation from Landsat images. The results illustrate that green space exposure limits pollution from traffic and reduces the exposure to noise, which overall benefits behavioral and psychomotor development. These findings can be used to conduct further research as well as infrastructure planning in urban neighborhoods to maximize the number of green spaces. In Pittsburgh specifically, a new parks tax has been implemented, where property owners must pay an extra $50 for every $100,000 of property value. With this tax, it is predicted that $10 million will be raised each year for park improvements in city neighborhoods throughout Pittsburgh. Likewise, throughout the nation, the Trust for Public Land is working to make a park accessible within a 10-min walk to every person. Although this will take time, it will provide social, health, economical and developmental benefits to all Americans.

Is Pittsburgh meeting that goal?
