Benefits of Removing Livestock from Rangelands to Sequester Carbon

f623b855-d229-4a32-abb2-770f8b14a604George 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.

CSIRO, BOM research shows how climate change will affect Australia

GR:  The fires of our industry have changed our planet.  There is enough added carbon in the atmosphere to produce the changes CSIRO and BOM predict.  How much worse things get depends on when we stop adding carbon.

The following is by Harry Tucker:  “AUSTRALIA’s two biggest science and weather bodies, CSIRO and the Bureau of Meteorology have released new climate change data and information on how it will affect Australia.

“There is very high confidence that hot days will become more frequent and hotter,” CSIRO principal research scientist, Kevin Hennessy said.

“We also have very high confidence that sea levels will rise, oceans will become more acidic, and snow depths will decline.

“We expect that extreme rainfall events across the nation are likely to become more intense, even where annual-average rainfall is projected to decline.”

“The projections are the most comprehensive ever released for Australia, and renowned science expert Dr Karl Kruszelnicki says they’re only just the tip of the iceberg.”  Source: www.news.com.au.
