Don’t Let the Green Grass Fool You

As a suburban environmentalist, Mike Tidwell, 45, of Takoma Park, Md., always felt like a walking contradiction.

Though he had quit his job as a journalist to work for environmental nonprofit organizations, Mr. Tidwell viewed suburbs (his own hometown is just outside of Washington) as places built “to defy nature,” he said, giving everyone “their own little kingdom of grass and space” — not to mention 3,000-square-foot houses, heated swimming pools and hulking S.U.V.’s.

For years, Mr. Tidwell led an environmental campaign, one with few followers. In 2002, he started a neighborhood cooperative to buy and distribute organically fertilized corn kernels to burn in pellet stoves (a lower-emissions alternative to traditional fuel-oil boilers). At first, the cooperative consisted of just him and three other residents.

But lately, after the release of Al Gore's “Inconvenient Truth” and last summer’s Live Earth concerts, his corn collective has ballooned to more than 70 members, some coming from more distant Maryland suburbs like Bethesda and Silver Spring. The group even built a 25-foot-tall cylindrical granary, holding 22 tons of corn, in a small lot belonging to Takoma Park.

Attitudes, Mr. Tidwell said, changed, too.

“In the American suburbs, people are suddenly literate in the language of carbon emissions and carbon footprints,” he said. “I’m hearing it in most mainstream places.”

But the problem with suburbs, many environmentalists say, is not an issue of light bulbs. In the end, the very things that make suburban life attractive — the lush lawns, spacious houses and three-car garages — also disproportionally contribute to global warming. Suburban life, these environmentalists argue, is simply not sustainable.

“The very essence of the post-Second World War America suburb militates against ‘greening,’ ” said Thomas J. Sugrue, a professor of history and sociology at the University of Pennsylvania. “Given the almost complete dependency of suburbanites on the car, it’s an uphill battle.”
