Earlier in the show we discussed what policies and approaches have been most successful in eliminating blight in cities like Baltimore. The work that Tom's next guest has done shows why eliminating blight is such an urgent problem. If you live in an area where blight is prevalent, it doesn’t just have a negative impact on your real estate values. It can have a very harmful impact on your health. Dr. Eugenia South has studied how blight impacts health and well-being in Philadelphia, a city with roughly 40,000 vacants. (That’s about 24,000 more vacants than we have in Baltimore.) Dr. South is a resident in the Department of Emergency Medicine at the Perelman School of Medicine at the University of Pennsylvania.
