Targeted neighborhoods for Greenness

EXPERIMENTAL

Using greenness as a therapeutic intervention, we will plant shrubs, grasses, young and mature trees (40-50 ft in height), so that we can evaluate changes in health and pollution, 2 years after planting.

Other: Greenness as a therapeutic intervention
