Ranchers dispute UN report that links cows to climate change

A major report from the United Nations focuses on the key role of our food and land use in fighting climate change. The Intergovernmental Panel on Climate Change says agriculture, forestry and other land uses produce nearly half of the world's methane emissions, a greenhouse gas that also comes from cows. But many ranchers argue the cow-climate change connection is overblown. One study says going vegan for a year reduces your carbon footprint by half as much as avoiding a single flight to Europe. Rancher Brandi Buzzard says the cattle she raises for beef are part of the solution to climate change, not the problem.  "When cattle graze on grass pastures, they are actually improving the grass and what they're grazing on," she said. "We are doing everything we can to improve our environmental footprint." Cow manure emits methane which can also come from cow burps, and yes, cow flatulence. Electricity generation and transportation like car emissions make up the majority of U.S.-produced greenhouse gases. But cows account for 2.6%. "So I think we can make more impactful changes in our lives through recycling, or walking to work, or using public transportation than we can by actually changing what we eat, because it will have such a minimal impact," Buzzard said. But changing what we eat, is what the report suggests. It argues, in part, that eating more plant-based foods and sustainably-produced meats can change land use and mitigate climate change. UC Davis professor Frank Mitloehner, who studies livestock and air quality, wants Americans to focus on the energy wasted on food they don't consume. "40% of all food produced in this country goes to waste and you know who the main culprit is? You and I," Mitloehner said. "So if you're really concerned about your personal environmental footprint around food, well, waste less."...MORE
