Imagine a world in which all people enjoyed a decent modern lifestyle without unduly degrading the natural resources on which future generations will depend. In such a world, people would live healthy, safe, well-educated lives, with ample opportunity to do productive and rewarding work, in a democratic, egalitarian society. Scandinavian nations already come much closer than the United States to providing such a lifestyle, with far lower per capita natural resource consumption.
How can everyone — including residents of impoverished developing countries — enjoy such a lifestyle without wrecking the earth's land, water, and air? In fact, we already have — or can easily develop — the necessary technology. It requires far less input of natural resources but often more input of labor; in short, it creates more and better jobs.
To clarify the idea that real sustainability creates jobs, here are examples from farms, cities, and businesses.
FarmsBack in 1985, economists Yujiro Hayami and Vernon Ruttan estimated the agricultural land and labor productivity of 44 nations. Their findings are stunning. (While the numbers date to 1980, they remain the best international comparisons.) In the developed world, farms in densely populated countries produced far more per acre, and far less per worker. Farms in Taiwan averaged about 16 times the output per acre of US farms, using about 23 times as much labor. Closer to home, farms in the Netherlands produced about twelve times as much per acre as US farms, using about two and a half times as much labor. There's nothing "primitive," however, about Taiwanese or Dutch agriculture. The Taiwanese use tractors the size of lawn mowers, multiple and mixed crops, and heavy fertilizer — though far less per unit of output than in the United States.
Of course, the United States has abundant high-quality agricultural land, so US farmers use land extravagantly. They're further encouraged by subsidies. For example, consider the tomato harvester. In the 1950s, California growers worried about the scheduled 1964 end of the Bracero program, a so-called "guest" worker program to supply cheap farm labor from Mexico. In response, federally funded researchers at the University of California-Davis developed both the machine and the special tough-skinned processing tomatoes that go with it. (Processing tomatoes go into cans and ketchup.) The giant harvester itself rolls along wide-spaced rows, digging up whole plants and shaking the tomatoes onto a conveyor belt, where a small crew tosses out those that are green or smushed. The system saves labor, but uses much more land, water, fertilizer, pesticides, and fuel (it saves labor, in other words, by being heavily natural-resource intensive). Today, machines harvest over 95% of California's tomato crop. (Just imagine if some of that research funding had gone into making farmworkers' jobs safer and more pleasant: better protective clothing, safer methods of applying pesticides, or wearable air-conditioners like those developed for the U.S. Army!)
But even in the United States, alternatives are possible. An Iowa State University study compared the Midwestern standard alternation of corn and soy, with a corn-soy-oat cycle and a corn-soy-oat-alfalfa cycle with livestock. Without lowering profits, the longer cycles increased yields while dramatically reducing the need for fertilizer, herbicides, and pesticides — but required more labor. In Ohio, corn and soy farmer David Brandt uses even more unorthodox methods. Instead of plowing, he plants with a seed drill. He keeps down weeds with a diverse mixture of cover crops, which he then mows to mulch the soil for the winter. The approach takes more labor, especially intelligent supervision, as it requires Brandt to carefully monitor conditions on every part of his fields. His fields, however, yield harvests as good as or better than conventional fields — yet they require far less fertilizer and herbicide, absorb rain better, resist droughts, and, best of all, build up carbon-rich humus.
What about farms in developing countries? According to economists Hayami and Ruttan, such farms produce low output both per worker and per acre. Nonetheless, farms in densely-populated Bangladesh still produced three times as much per acre as farms in the United States! And Hayami and Ruttan just estimated averages; in general, small farms produce more per acre than large farms, even though they usually occupy inferior land. According to a new UN report, small peasant farmers could easily feed the entire populations of developing countries with existing labor-intensive, environmentally friendly agricultural technologies—were it not for corruption, extreme inequality, and misguided attempts to impose inappropriate "modern" crops and techniques.
CitiesCompare sprawl cities like Las Vegas (4,300 people/sq. mi.) to relatively compact cities like New York (27,500 people/sq. mi.). New York uses proportionally less land and capital to perform the essential urban function of connecting people via walking, bicycling, elevators, and mass transit. In some of the richest parts of New York, like my Upper West Side neighborhood, people pay top dollar to live in densities of over 200,000 people per square mile. (I can zip, through a hole in the ground, the two miles to work, walk four blocks to concerts or shopping, and step into Central Park next door! Who needs a car?)
Moreover, the better a city connects people, the more jobs it creates by facilitating what Adam Smith, and Henry George, called "the division of labor." Such specialization allows enormous gains in productivity, and encourages development of new products and new technology. Smith observed that innovation and economic growth start in cities; pioneering urban critic Jane Jacobs developed this theme at length in The Economy of Cities (1969) and Cities and the Wealth of Nations (1984). She especially noted how in cities people of vastly different skill sets bump into each other — sparking the "aha!" that your technology can solve my problem.
Besides bringing people together, cities save materials and energy. A study in Atlanta found that average households in multifamily units used only 60% as much energy as in single family detached houses. Average residents of New York City produce less than a third as much greenhouse gases as average Americans. And while New York apartments seem cramped by United States standards, a 500 square foot New York one-bedroom would seem palatial to a Japanese family! (How do the Japanese manage? Simple. Every morning they roll up their futons and stuff them in a closet!)
Yet these days, while new development sprawls into farmland and woodland, large areas of older central cities decay and empty out. Urban sustainability means reversing this process. It means renovating urban infrastructure, revitalizing urban services, repairing or upgrading old buildings, filling in vacant lots. What do these activities have in common? Jobs. Lots of jobs. Especially: skilled, interesting jobs. Nonetheless, viewed from Google Earth, New York City looks moth-eaten. The city classifies 6% of its land as vacant — not including those with surface parking lots, or abandoned buildings.
Like Japanese manufacturers or Taiwanese farmers, small to medium businesses in the United States and elsewhere suffer from a shortage of natural resources and capital relative to labor — including the owners' labor. They make do by operating in cramped spaces with used equipment. They concentrate in fields like recycling and renovation, or services like health care, laundry, or repair of autos and computers. They are the true "job creators"; they generate many times big businesses' jobs per dollar of assets or sales. For major innovations, we depend on entrepreneurs who start small — like Hamdi Ulukaya, who founded Chobani yogurt in an abandoned Kraft plant in upstate New York, scrounging second-hand equipment off the Internet. Yet, as documented by journalist and New America Foundation senior fellow Barry Lynn, successful innovators are disappearing, due both to growing patent monopolization and the unavailability of finance. Small businesses could rely on small banks, back in the days of It's a Wonderful Life (1946) — and in fact they could until Congress repealed restrictions on interstate banking in 1994. Bank officers served the community (at least the white community), making loans based on personal histories and an intimate knowledge of the local economy. No more. Today's giant banks lend — if they lend at all — according to formulas dictated by headquarters, formulas that do not favor a Turkish immigrant with a new recipe for yogurt, let alone Madge's storefront bakery. Retail banking jobs have become mindless paper-pushing.
Putting It TogetherIn farming, in cities, and in businesses, there's a common theme: we already have the technology to produce and live and work in ways that vastly reduce stress on natural resources — and simultaneously create more jobs. The obstacles are political. In the United States, we're up against a system that engenders waste of agricultural land, suburban sprawl, hollowed-out cities, and failing small businesses. First and foremost, our tax system encourages the underuse of valuable urban land and the proliferation of urban sprawl. The fossil-fuel industry enjoys tax and other subsidies, including the implicit subsidy of free carbon-dioxide dumping. These misincentives and subsidies artificially lower the cost of transportation and other energy-intensive activities, such as the manufacture of steel, cement, and nitrogen fertilizer. Federal and state governments also subsidize uneconomical water development in dry regions, notably California. Cities themselves feed sprawl by extending roads and utilities, below cost, to well-connected developers in the boonies. Older cities withdraw services from poorer neighborhoods while granting tax favors to richer ones. Meanwhile, after President Reagan's election in 1980, the US federal government stopped enforcing anti-trust laws, setting off a merger frenzy among corporations. As Barry Lynn writes in Cornered: The New Monopoly Capitalism and the Economics of Destruction (2010), "Even as we were reassured on a daily, sometimes hourly, basis that America was the greatest 'free market' economy in the world, a tiny elite engineered the most phenomenal roll-up of political economic power in our history." During the financial crisis of 2008, US Treasury Secretary Henry Paulson, previously CEO of Goldman Sachs, oversaw the subsidized shotgun marriages among the too-big-to-fail banks, making the survivors (including Goldman) even too bigger to fail—or to lend to small business.
Suppose that, by waving a magic wand, we could simply undo this rigged system. Yes, there would be disruptions and hardships. Many coal miners would need new jobs, perhaps restoring devastated landscapes. But with skyrocketing fossil-fuel prices, farmers would turn to those energy and land-saving, labor-using advanced technologies. Many of us would desert the suburbs for the cities, setting off a wave of urban renovation. In place of resource-wasting and labor-squeezing giant corporations, a fleet of smaller firms would compete for employees, driving up wages. With tax loopholes plugged — and tax penalties removed from productive enterprise — government agencies could provide excellent infrastructure, high-quality health and education services, and generous safety nets. That's what sustainability squared means. We can have it all; we can save the environment using existing technology to create decent jobs and better lives for everyone.
