The Plan To Literally Expand New York City

What if we added the equivalent of over 1300 football fields to the tip of Manhattan? This was the proposal of a recent op-ed in The New York Times - increasing the size of the borough by about 12% in order to mitigate two of its most pressing problems. There’s evidence from all over the world that doing this can be a useful technique for crowded ocean-side cities. But the process to do so - reclaiming land from the ocean - is rife with potential downsides. So is this a proportional response to gigantic problems? Or a zany harebrained scheme that’ll do more harm than good?
