Tim De Chant at Per Square Mile has noted that rich urban areas have way, way more trees than poor areas in the same city. In fact, the difference is so stark that income inequality can be seen from space. The satellite images above are low-income West Oakland and high-income Piedmont, and I probably don’t have to tell you which is which.

De Chant has collected images from four U.S. cities and two international cities, and in every one, the wealthier areas are conspicuously more leafy. Since trees increase property values, this is a classic case of the rich being given whatever they need to get richer. And considering the other things trees do for us, it’s also a case of the rich getting to be smarter, cooler, and have fewer allergies.
