"Trees along big city streets have a rough life. Between pollution, development, and vandalism, street trees die off at a pretty alarming rate. One New York artist thinks if people knew more about street trees, they’d appreciate them more -- and treat them better. ...[The] artist recruited arborists and neighbors to record messages about the city's trees. She placed markers in the cement listing numbers to call to hear the recordings."
