Volume 22 • Issue 04 • 2018 and carbon cycling through 100% grass-fed ruminants, into nutrient-rich, flavoursome, high welfare, ethical meat and milk. Become a carbon-friendly omnivore. Vote with your fork to encourage more farmers to make the switch: support carbon sequestration by only eating meat or drinking milk from animals certified 100% grass-fed. To find such food go to the website of the Pasture Fed Livestock Association, which is the only UK organization to certify meat and dairy as 100% grass-fed. Eat your beef and drink your milk guilt-free. See our Courses page to learn more about grazing cattle for soil health and carbon sequestration as well as productivity, animal and human health.
