“Take two walks and call me in the morning,” might be among future prescriptions. Pediatrician Dr. Robert Zarr has created a database of 350 parks and green spaces in Washington, DC, integrating data into Unity Health Care’s system; doctors can enter a patient’s zip code and create an exercise plan.
