Vitality grows on trees
Urban foliage has surprising health, economic benefits
New research suggests that trees are hard at work in cities. A single tree, one study found, can help deter crime in its immediate vicinity. Babies born to mothers with a tree close to their house are less likely to be underweight. And trees raise the property value of nearby homes by nearly $13,000, according to one analysis. Trees should be counted among those urban dwellers who make important contributions to the life of the city.
