DALLAS – The far-left Humane Society for the United States is peddling meatless lunch menus to schools across the country and two in the heart of beef country just took a bite.

Two Dallas-area school districts – Highland Park Independent School District and Dallas Independent School District – will hold an all veggie Lean & Green Day lunch as a way to celebrate Earth Day, Dallas Culture Map reports.

“It’s exciting to see Dallas and Highland Park ISDs’ child nutrition departments providing healthy, delicious and sustainable school lunches in honor of Earth Day,” HSUS’ food policy manager Eddie Garza told the news site.

Highland Park ISD will hold its Lean & Green Day today with a mucho beef and bean burrito, made with fake meat “crumbles,” spinach and cheese lasagna, and steamed rice and edamame. Dallas ISD’s event is April 30, and will feature baked ziti with fake meat, enchiladas, salad, and chicken salad with fake meat.

The Lean & Green Days are part of a broader effort by HSUS to root meat out of school cafeterias across the country, most notably through its “Meatless Mondays” campaign. Last fall, the Philadelphia School Reform Commission passed a resolution “in support of Meatless Monday” after HSUS “worked to build support or meatless menus in Philadelphia schools,” The Philadelphia Tribune reports.

“They’re really looking forward to expand meat-free options in the future,” said Kristil Smith, another HSUS food policy manager.

“We support it because it’s a great way to reduce the number of animals suffering on factory farms,” she said.

Schools in Buffalo, Detroit, Houston, Los Angeles, and Boston have also reportedly signed on.

Boston students are “filling their trays with black bean burrito bowls, garden fresh salads topped with chickpeas, protein-packed chili, and more,” according to HSUS.

Boston Public Schools’ food nutrition deputy director is totally on board.

“Offering students nutritious meals as part of the Meatless Monday programs allows us to meet the diverse needs of the families in our district while getting the week off to a healthy start,” she said.

“Now, every Monday, our students know they can look forward to a high-quality meatless option in addition to the choices they already have.”

In Dallas, the Lean & Green Days are really hitting locals where it hurts.

HSUS’ anti-meat crusade is taking its toll on the beef industry and convincing local kids to go green will only make matters worse.

From the New York Times:

The Texas cattle inventory has dropped by more than 22 percent since 2011, mostly because grazing land has been lost to drought and suburban development. Three years ago, more than five million female cows in Texas were bearing calves. Today, that number is about 3.9 million …

Rising prices, more health-conscious consumers and the rise of efforts like Meatless Mondays, aimed at convincing people that paring down on meat is good for them and the planet, have dampened consumption.

Americans eat the equivalent of about 54 pounds of beef a person each year, down from about 65 pounds a year in 2007.
