George Wuerthner: “Rangelands make up a large proportion of the Earth’s surface, and the soils hold a significant amount of sequestered carbon. Rangelands are estimated to contain more than one-third of the world’s above and below ground carbon reserves.[i] As a consequence, there is interest in determining the potential for soil carbon sequestration in rangeland soils, and whether livestock grazing helps or hinders this sequestration.
“Given the existing condition of many rangelands, the biggest concern is maintaining current carbon, and avoiding losses through soil erosion, degradation of plant productivity and other changes that lead to soil carbon losses. In other words, the best way to reduce CO2 emissions from rangelands globally is to reduce rangeland degradation. Since livestock grazing is frequently the major source of rangeland degradation, a reduction in grazing pressure, can in many ecosystems, potentially preserve more soil carbon” Source: www.thewildlifenews.com.
GR: Excellent article. Cites evidence showing that livestock grazing reduces soil CO2. Moreover, domestic grazers remove plants that wildlife need, and they damage soil microorganisms that enrich and stabilize the soil and help block weed invasions.
