What If Every Human Vanished Tomorrow? Wolves Would Move Into Your Street.

What if every human vanished tomorrow? Under New York, pumps push about 13 million gallons of water out of the subway on a dry day. This episode follows the real nights when that protection failed, from Hurricane Sandy in 2012 to the 2003 blackout, and the two places where land already shows what happens when people leave, the Chernobyl zone and the Korean border strip. The second half imagines the grid going dark with nobody left to restart it, the subway flooding within two days, and centuries of forest swallowing the suburbs.
