Let’s move this conversation forward; or, (another) study: pasture-raised cows produce four times more methane emissions than feedlot cows

January 23, 2012

A new study confirms higher rates of methane emission from grazed cows over feedlot cows. Abstract and full study available here:

Direct measurements of methane emissions from grazing and feedlot cattle

This study, citing and building on studies which already demonstrate that cattle farming represents a mass contribution to the emission of methane–one of the most consequential greenhouse gasses–examined and measured output from large samples of cattle in undisturbed (non-laboratory/non-constructed) settings.

Its main conclusion: “These measurements clearly document higher CH4 production (about four times) for cattle receiving low-quality, high-fiber diets than for cattle fed high-grain diets.”

To advocates of pasture-raised beef and dairy: Please start discussing this kind of information and please stop spreading the myth that pasture-raised beef is good for the environment. That there are a lot of problems with agriculture-in-general, including plant agriculture and monocultures, is not in dispute. But from the mass destruction caused by grazing, to the mass methane emissions, raising animals on┬ápasture is not simply detrimental; it’s more detrimental than on feedlots, in terms of land/habitat destruction and greenhouse gas emissions.

This article by Mike Tidwell was recently brought to my attention, and impressed me as a very good, simple overview of the environmental impact of carnism, on humans as well as ecosystems and individual animals. Tidwell points out that even many folks’ beloved fall-back, “free range” and “sustainable” chicken and egg farming, produces far more greenhouse gas emissions than its terrible factory-farming sibling– 14 percent more!

This is to say nothing of the myth of “humane” meat that we have discussed elsewhere.

We’ve listened to the “humane” meat-ers. We’ve listened to the Weston A. Price Foundation’s non-scientists and non-nutritionists misconstrue information about teeth, soy, cholesterol, and raw meat. We’ve listened to Lierre Keith straight-up hate on vegans and paint caricatures of health and sustainable agriculture. We’ve listened to Michael Pollan and Joe Salatin’s carefully (and conveniently) constructed happy-meat, return-to-pasture narratives. We’ve listened to people who don’t come from gatherer-hunter cultures say, “let’s hunt, then!” and we’ve tried not to be dicks when we’ve pointed out that, if even a fraction of billions of today’s non-tribal humans started hunting for their meat, ecosystems would almost immediately shatter. We’ve listened to Barabara Kingslover as she drives 3,000 miles in her car to eat another location’s local food. We’ve listened to really excited ex-vegan bloggers talk about how they literally feel the energy of nutrients x, y, and z rushing through their body the minute they eat meat again for the first time (something which isn’t physiologically possible.) We’ve gotten a good share of what anti-vegans–both the subtle and the not-so-subtle ones–have to say. For all our faults and snark, we’ve tried to listen–we actually really have.

And for all of this, there’s one thing they all seem to say some version of, and I agree with it: We need better, more diverse, more creative, less mono-culture based farming methods. Nobody here is saying otherwise.

But it’s time to move the conversation forward: the ethics of, and cognitive dissonance that is necessary for, “humane meat”, grass-fed meat, and pasture farming are highly questionable; and we have to contend with those questions now if we want to deal with the crises of ecology, psychology, and ethics that are literally destroying the earth.

There is, at this point, simply too much available information to ignore regarding the destructiveness of animal farming and the unnecessary suffering of animals. There is too much information to ignore regarding the existence of viable, healthful, plant-based alternatives to meat diets and animal farming. We can’t continue to ignore this information if we want to have conversations about diet that aren’t disingenuous. We can’t refuse to discuss the fallacy, the gaping logical inconsistency, of “humane” captivity and slaughter, and the environmental destruction of animal farming–the latter of which is an issue for both entire species and their individual bodies. We can’t keep falling back on the simplistic vegan straw man of “but monocultures–but soy–but the paleocene–but protein”. These straw-men have been debunked to death. Healthful, animal-friendly plant-based alternatives to this mess of meat agriculture and carnism exist, right now, today. Just because these plant-based alternatives are inconvenient to a Western culture that is steeped in the ideologies and practices of meat, doesn’t mean they don’t exist. Our refusal to look at them does not erase their reality.

If you need more information about any of these issues or about striving towards sustainable plant-based lives, we’ve discussed it a lot in this blog. Please refer to other posts such as those here and here, do a quick google or JSTOR search, or refer to our resources page or our sustainable vegan agriculture page.
