Old Manhattan Had a Farm
5th October 2008
Read it.
At first sight, the idea seems plausible. True, vertical farming would be a non-starter if urban rents were higher than rural rents. But we all know that land is just as cheap in downtown Manhattan as it is in rural Nebraska, right? One wonders, though, why farming moved off the island a more than a century ago.
Professor Despommier claims that food grown indoors would be pesticide-free, unlike that dirty outdoor produce. Once again, totally plausible. Big American cities are as free of rats and roaches as Ireland is of snakes. The Museum of Natural History has a glass case containing the last rat found in New York City, way back before World War I. (Just don’t look down at the tracks when you are waiting for a subway).
But then if we admit there are millions of rats and billions of roaches, then the crops growing in vertical farms would have to be protected by enough rat and roach poison to kill Xerxes’ army. Fortunately, in rat- and roach-free urban America, that is not a consideration. And even if it were, we would not need to worry that health inspectors would be bribed to overlook the rodent droppings and roach eggs in our tenth-story grown arugula. The civil servants in New York City, Chicago and Philadelphia are known worldwide for their incorruptibility.
