Juxtapositioned

First look up and see the blue sky echoed in the windows of tall buildings and then look down to see where busy hands and trowels have just been. And while these two things, the skycrapers and the terrace, green with newly planted grasses and perennials, seem perhaps entirely at odds and of two different worlds, they are both really these modern, completely fabricated and fantastic creations. They are these ecosystems in the skyline, one filled workers and the business of the life of man in the city, the other a miniature manmade prairie. Perhaps in a way they could even be compared to the complicated systems only recently discovered that exist and carry out all the business of living up high in the canopy of old growth forests.
