Urban Trees and Public Health

In a NPR interview transcript, a researcher who tries to quantify exactly how the loss of trees (particularly urban trees) affects public health.
That's a really unique opportunity. Imagine if you were trying to look at the effect of trees growing on someone's health and I got 100 people, I put them in 100 identical houses, and I planted trees in front of 50 of those houses and then waited. It would take 40 or 50 years before you found anything because trees grow really slowly. It's hard to see significant changes quickly. On the other hand, trees die really quickly. That's why you have this unique opportunity to see a big change in the natural environment in a short amount of time.
