There’s a wealth of plants in all sorts of unexpected places. (Not to even mention Central Park, one of the most glorious greenspaces ever.) NYC is the greenest city I’ve ever seen. Parks, rooftop gardens, tree-lined streets, window boxes.
And then there’s the unplanned greenery.
A deeply unsettling book came out a few years ago, called The World Without Us. The author, Alan Weisman, studied places where humans used to live but don’t anymore, like Chernobyl or the Korean DMZ. He describes what the planet would be like if humans were abruptly removed from it. Based on his research, he concludes that it would take only two to three days for changes to begin in a place like New York City.
Without pumping, the subways would flood. The foundations of the city would begin to erode.
