Urban farms are lovely but they aren’t actually green says environmentalist
New York doesn’t need more farms to be sustainable, it needs more apartments, more offices, more factories, more skyscrapers

Consider some iconic acre of Brooklyn vacant lot. You could grow food on it—or you could throw up a 30-story apartment complex housing 600 people. That’s 600 people who won’t be settling in low-density exurbs where they would be smeared across 60 acres of subdivision; in turn, those 60 acres of vacant exurb could remain farmland or forest. Using communal laundromats and lacking basements to put junk in, those new Brooklynites would lead lives of anti-consumerism. And because they would use mass transit instead of driving everywhere, their carbon footprints would be roughly a third as large as the average American’s.
That fundamental land-use equation is the key to understanding how cities promote global sustainability. By concentrating high-density housing, business and lifestyles inside its borders, New York lifts enormous burdens from the ecosystem outside its borders, but that potential is squandered when we consign pristine brownfields to low-density crop-growing. We may root for the community gardeners in their eternal battle with real-estate developers, but it’s the developers who are, despite themselves, the better environmentalists.
