Dear EarthTalk: I know that some people abstain from meat on Fridays for religious reasons, but what’s the story behind “Meatless Mondays?”Sasha Burger, Ronkonkoma, NY

Meatless Monday—the modern version of it, at least—was born in 2003 with the goal of reducing meat consumption by 15 percent in the U.S. and beyond. The rationale? Livestock production accounts for one-fifth of all man-made greenhouse gas emissions worldwide and is also a major factor in global forest and habitat loss, freshwater depletion, pollution and human health problems. The average American eats some eight ounces of meat every day—45 percent more than the U.S. Department of Agriculture’s recommended amount.

An outgrowth of the Johns Hopkins Bloomberg School of Public Health’s Center for a Livable Future, the Meatless Monday project offers vegetarian recipes, interviews with experts, various resources for schools, organizations and municipalities that wish to promote the initiative—and regular updates on Facebook and Twitter. “Going meatless once a week can reduce your risk of chronic preventable conditions like cancer, cardiovascular disease, diabetes and obesity,” the group reports. “It can also help limit your carbon footprint and save resources like fresh water and fossil fuel.”

The Meatless Monday concept actually dates back to World War I, when the U.S. Food and Drug Administration (FDA) urged citizens to reduce their meat, wheat and sugar intakes, since such foods took more energy to produce than others. Americans willing to cut back—even just one day a week—would be supporting the troops and helping to feed starving Europeans. To encourage participation, the FDA coined the terms “Meatless Monday” and “Wheatless Wednesday” and published vegetarian cookbooks and informational pamphlets. The campaign was resurrected briefly during World War II, but then died down.
