NASA scientists have produced a map of the first "observation-based estimate of lawn surface area in the United States," which displays "fractional turf grass area" in varying shades, from white to deepest green. The result is a verdant constellation spreading from sea to shining sea. The scientists who produced the map say that more surface area in the U.S. is devoted to lawns than to any other single irrigated crop in the country, and that lanws appear to cover more than three times the number of acres that irrigated corn covers!
