|Dead tree in New York City|
Susan Phillips reports for StateImpact that the city of Philadelphia has an estimated 130,000 street trees and plants between 1000 and 3000 new trees each year--each one costing between four to six-hundred dollars.
So it would make good economic (as well as environmental) sense to find the culprit before a tree succumbs.
Susan took a walk with a guy from Boston named Bob Ackley who knows about another cause of tree deaths that you might not suspect--underground gas pipe leaks.
The outcome of that stroll is the interesting audio story below.
