income inequality - trees from space

this is great article, you can see income inequality from Google earth, poor neighborhoods have fewer trees than wealthier.  So "greening of the neighborhood" is directly proportional to income inequality.  Above is example from chicago, top is hyde park, Obama's neighborhood at the Univ of Chicago ("the only neighborhood where whites and blacks join together against the poor....") and Englewood, a neighborhood currently under renovation with a humongous federal grant, but still remains economically challenged (or poor). notice the green difference?
