Few sounds say American summer like a mower running somewhere down the street on a Saturday morning.<\/p>\n
The machine promised something simple and satisfying, a neat, even carpet<\/strong> of green the whole block would admire.<\/p>\n Pull the cord, walk the rows, and in half an hour the yard looks cared for.<\/p>\n It is one of the most ordinary chores in the country.<\/p>\n What almost no owner pictures is the invisible cloud<\/strong> the little engine leaves hanging in the air behind them.<\/p>\n The lawn is the largest thing Americans grow.<\/p>\n Turf covers more than 40 million acres<\/strong> of the country, more ground than any irrigated crop, from front yards to ball fields to golf courses.<\/p>\n Keeping all of it short takes a small army of engines.<\/p>\n By some counts more than 50 million Americans mow every week in season.<\/p>\n In some states, turf now covers more than a fifth of the available land.<\/p>\n Tens of millions of gas mowers run most weekends through the growing season.<\/p>\n Together they burn something like 800 million gallons<\/strong> of gasoline a year just cutting grass.<\/p>\n Keeping it green and short has become a national habit few ever question.<\/p>\n Your car has spent decades getting cleaner.<\/p>\n A small mower engine has not.<\/p>\n Most gas mowers still run without a catalytic converter<\/strong>, the part that has scrubbed car exhaust since the 1970s.<\/p>\n For decades these small engines were barely regulated at all.<\/p>\n So the engine burns its fuel messily, throwing out far more smog forming gas per drop than a modern car does.<\/p>\n The EPA estimates<\/a> that gas powered lawn and garden equipment makes up around 5 percent<\/strong> of the nation’s air pollution, and more than that in cities.<\/p>\n California air regulators have warned that landscaping engines could soon out pollute every car on the state’s roads.<\/p>\n An hour behind the mower can put out as much smog forming pollution as driving a new car dozens of miles, and an older machine far more.<\/p>\n The little engine works hard for its size, and burns dirty the whole time.<\/p>\n The exhaust is only half of it.<\/p>\n The other half never makes it into the engine at all.<\/p>\n Every summer, topping off mowers and gas cans, Americans spill fuel<\/strong> onto driveways and grass across the country.<\/p>\n The EPA puts that number at more than 17 million gallons<\/strong> a year, more than the Exxon Valdez leaked into the sea.<\/p>\n That gasoline soaks into soil, evaporates into the air, and washes toward storm drains.<\/p>\n Even small spills keep evaporating off the driveway and feed the summer smog.<\/p>\n And then there is the noise, since many mowers scream past 100 decibels, into the range that can damage hearing.<\/p>\n Neighbors a few doors down can hear it, and so can your own ears up close.<\/p>\n Here is the part the tidy look hides best.<\/p>\n A lawn kept short and uniform is close to a dead zone<\/strong> for the small life that used to fill it.<\/p>\n Cut every week, the clover and dandelions never flower, and the ground nesting insects never get a foothold.<\/p>\n A sharp weekly trim looks tidy and leaves those small pollinators shut out.<\/p>\n Then scientists at the USDA Forest Service<\/a> tried something almost lazy.<\/p>\n They mowed suburban yards less often, every two or three weeks instead of every week, and simply counted what came back.<\/p>\n The lawns cut every three weeks grew up to two and a half times more flowers than the ones cut weekly.<\/p>\n The yards filled with flowers, and the researchers logged 93 species of bees<\/strong> feeding in ordinary lawns that had been near silent before.<\/p>\n That was nearly a quarter of every bee species native to the region.<\/p>\n None of this means your yard is the enemy, or that you have to let it run wild.<\/p>\n The point is how little it takes to change the math.<\/p>\n Mowing a bit less often, even every other week<\/strong>, lets the lawn feed pollinators<\/a> without looking neglected.<\/p>\n Switching to an electric or battery mower erases the exhaust and most of the noise in one move.<\/p>\n It also skips the oil changes, the fouled plugs and the trips to the gas station.<\/p>\n Even leaving one corner of the yard to grow gives those bees somewhere to land.<\/p>\n Skipping the spill with a careful can, or shrinking the mown area even a little, does the rest, the same small awareness behind so much everyday yard care<\/a>.<\/p>\n The neat green lawn was never the whole story.<\/p>\n What lives in it, and what drifts off it, was the part no one was selling<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" Few sounds say American summer like a mower running somewhere down the street on a Saturday morning.
