Arenāt Vegetarian and Vegan Diets Better for the Environment?
Some people choose vegetarian or vegan diets because they believe they are better for the environment. But while thereās no doubt that CAFO meat is harmful for the environment, the same canāt be said for animals that are raised on pasture. In fact, several scientists have made the argument that grazing animals are critical for healthy ecosystems and preventing desertification, a growing problem around the world. via Chris Kresser

Stanley 2018 ā This paper conducts a life-cycle assessment, including a direct measure of carbon flux, on various livestock finishing systems and shows that properly managed livestock create an ecosystem that is a net carbon sink instead of net carbon emitter.
Teague 2017 ā This paper is an overarching discussion on various types of grazing management and the potential for proper (holistic) management to regenerate ecosystem function and grazing land livelihoods. It also dives into the shortcomings of most grazing research that reduces whole ecosystem complexities into individual factors.
Teague 2016 ā Properly managed grazing, if applied to 25 percent of our crop and grasslands, would mitigate the entire carbon footprint of North American agriculture.
Rowntree 2016 ā āFrom this data, we conclude that well-managed grazing and grass-ļ¬nishing systems in environmentally appropriate settings can positively contribute to reducing the carbon footprint of beef cattle, while lowering overall atmospheric CO2 concentrations.ā
Peters 2016 ā This study modeled human carrying capacity under 10 diet scenarios. Even though carrying capacity was generally higher for diets with less meat (likely due to modeling being based on feedlot stats and the cropland needed to grow the feed), āthe carrying capacity of the vegan diet was lower than two of the healthy omnivore diet scenarios.ā
Machmuller 2015 ā āFarms accumulated carbon at 8.0āMgāhaā1āyrā1, increasing cation exchange and water holding capacity by 95% and 34%, respectively. Thus, within a decade of management-intensive grazing practices, soil carbon levels returned to those of native forest soils and likely decreased fertilizer and irrigation demands. Emerging land uses, such as management-intensive grazing, may offer a rare win-win strategy combining profitable food production with rapid improvement of soil quality and short-term climate mitigation through soil carbon-accumulation.ā
Herrero 2011 ā This paper specifically calls out the often quoted but incorrect stat that 51 percent of greenhouse gas emissions are from livestock. The actual number is closer to 15 percent, but itās important to remember that these numbers are derived from industrial livestock production methods. Papers above from Richard Teague and Paige Stanley show an alternative approach whereby properly managed livestock can regenerate grassland ecosystems and sequester carbon.
