Problematizing ecology, local, and grass-fed… again

March 30, 2011

I originally posted this as a comment, then thought, well, this is a lot of writing just to be a comment. So here goes:

Eighty percent of corn and soy crops are used for livestock feed, not for vegan food. The problems of grain, soy, and monocultures are simply not ones that can be pinned on the vegan movement. To paraphrase Gary Francione, the problem of designer foods is not inherent to veganism any more than the problem of designer clothes is inherent to wearing clothes. There are plenty of designer foods that meat-eaters eat, and there are plenty of vegans who eat mainly local and organic, plenty of vegans who don’t eat soy or tons of corn and wheat, etc. To claim that all vegans eat all grain and soy, or that a vegan diet only consists of grain and soy, is a disingenuous straw-man argument.

Veganic/stock free permaculture is a thriving practice all over the world. It seems many locavores are willfully ignorant of this fact, and I’m not entirely clear why. Veganic permaculture is by far the most sustainable farming practice. There are many books and internet resources on this if you need more information.

Grass fed livestock don’t partake in the problem of corn and soy feed. But pasture/grass fed animals require more than twice the land of factory farmed animals. Grazing is one of the worst environmental problems that exists. Overgrazing has trampled and compacted land and been the largest contributor to desertification. Two-thirds of the American West, for instance, is grazing land. Clearing land for pasture is the major reason for destruction of forests and biodiversity including the atrocity of rainforest destruction. This is simply not a problem with even the least sustainable plant diets. Even the most industrialized plant diets use exponentially less land per yield than meat diets, especially grazed meat diets. Grazing is one of the most ecologically absurd situations humans have ever created. One researcher, Vacliv Smil, who has done very careful math has estimated that by 2050, if we are to feed the world on a meat diet, we will need 67 percent more land on the earth. Again, there is no comparable number for even the least sustainable plant agriculture, as plant protein is much higher yield per energy input than meat, and is consumed directly instead of being turned into an animal first.

Cows emit massive amounts of methane, one of the worst greenhouse gasses, and it is well documented that this is a major cause of global warming, surpassing all forms of transportation combined.  Grass fed and free-range livestock emit many times more methane than industrial livestock, in fact, because they live much longer. Again, this problem is simply not comparable to the problems of plant agriculture. Plants are not farting and stomping us to extinction.

Raising livestock, even grass-fed, is also by far the world’s number one cause of water usage and water pollution. Again, not comparable to the water usage of plant agriculture.

Furthermore, the issue of transportation of food over long distances is often cited by locavores, but the truth is much more complicated. The simple equation of food miles does not account for whether or not irrigation is used, whether or not food is grown in hothouses, whether or not food is in season, how food is stored, how food is cooked, how much food was shipped where and how, whether or not it is animal or plant food, etc. In short, transportation is about ten percent of a food’s energy cost. To quote James McWilliams, who has many problematic ideas but is right-on when it comes to food miles, “To take an extreme example, a shipper sending a truck with 2,000 apples over 2,000 miles would consume the same amount of fuel per apple as a local farmer who takes a pickup 50 miles to sell 50 apples at his stall at the green market.” Furthermore, simplistic food mile equations do not account for people who live in regions where food is not available, which opens up a sizeable, incredibly complicated can of worms in terms of human rights and food access. The local ethic, despite its benefits, simply does not take responsibility for the problem of food access in a globalized world where food is an inherently global issue. I am not saying I have a perfect answer to this problem, but I am saying that food access in a globalized world is complicated, and it deserves to be dealt with in a complicated way, especially if people who have social and economic privilege are claiming to be concerned with human rights.

But I digress. I don’t at all mean to tear local agriculture a new asshole. There are many reasons to eat local, especially in places where, unlike the Arizona desert where local food–including all meat–is all sustained by irrigation, local makes sense. I support eating local for several reasons, and I eat local as much as I can (and I’m a vegan… gasp). The point, rather, is that just because something is local does not mean it is the most environmentally friendly option. A life-cycle assessment (LCA) is a much more honest and comprehensive way than food miles to figure which food is the most sustainable.

If you are going to eat animal food, grass-fed meat from permaculture farms is the most sustainable way to do it. But veganic permaculture is exponentially more sustainable due to the minimized effects it has on land, water, and greenhouse gas emissions. Many of the less sustainable techniques of plant agriculture are more sustainable than the most sustainable forms of animal agriculture.

And this does not begin to get into the issue of the rights and interests of individual animals. I happen to believe that an egalitarian and ecologically friendly world is not possible when our personal and mass psychology is imbued with the idea that it is okay to unnecessarily use most of the world’s sentient creatures as mere instruments to our own ends. But that aside, I do understand the issue of animal rights lives in complicated philosophical, emotional, and spiritual territory. However, the issue of whether or not eating meat is good for the environment, especially in the long run, is quite simple: it isn’t. And there are viable, thriving alternatives. We might not like them because they challenge our deep-rooted food habits and assumptions, but within this generation there will be 10 billion people in the world, and save hitherto unknown technological interventions, there won’t even be any more land for meat-heavy diets.


The Humane Myth

March 6, 2011

From the Humane Myth project:

***

Aren’t “humane” animal products more sustainable?

Quite often, those promoting “humane” animal products suggest that these products are more sustainable than animal products from large industrialized operations. At first glance, this may seem to be true. When one pictures a traditional small-scale farm with large open pastures, and then, in contrast, a huge industrial facility surrounded by giant lagoons of waste products slowly leaching into the countryside, it seems clear that producing animal products on a small scale is better for the environment. However, the reality is far more complicated than these simple images may suggest. A more fundamental question to ask is whether any form of animal agriculture, if practiced on the scale needed to meet existing demand for animal products, is good for the environment, or sustainable.

As it is today, we know that humanity as a whole is living in a manner that is far from sustainable. In fact, it is estimated that our species is annually using resources at least 20% faster than the earth can renew or replenish. Those of us living in the wealthier countries are using up resources several hundred percent faster than the earth can sustain, with the extra load being absorbed by the extraction of resources from poorer countries. There are many signs that this imbalance is not only causing injustice and suffering on an unimaginable scale, but is also destabilizing our ecosystem. The most well known of these signs are global warming and the depletion of fresh water. Scientists worldwide are telling us the same story–if we don’t make major changes in the way we live, there are going to be drastic consequences, not in the distant future, but much sooner than most of us realize.

A recent study carried out by United Nations scientists demonstrated that animal agriculture is the number one source of greenhouse gas impact, making a greater contribution to global warming than all cars, trucks, buses, air planes, trains, and ships combined. This effect is based on the unavoidable biological realities of animal agriculture itself, realities that are present in all styles of animal farming. Regardless of the style of production, from the smallest scale farms to the largest industrial operations, the level of greenhouse gas impact per unit of animal products created is going to be in the same catastrophic range.

So as human population continues to spiral upward, and as more and more of the world’s people are convinced to adopt a western-style diet replete with animal products, the disastrous impact on the environment will expand regardless of the method being used to produce animal products. As it is, consumption of meat has gone up 500% in the past half century, and if present trends continue, will double in the next half century.

Further, the production of a diet based on on meat, milk, and eggs uses several times more energy and water, and creates more toxic pollution, than a diet based on grains, vegetables and fruits. We can already see that the fight for dwindling supplies of oil is causing armed conflict around the world. Many experts on geopolitics predict that it will not be long before wars are fought over water.

Lastly, there is the issue of available land. As it is, the rapidly expanding human population is constantly reducing the amount of land available for farming as well as rapidly deforesting the small percentage of wild lands that remain. Producing “humane” animal products requires at least double the amount of land required for the industrialized style of farming adopted in wealthy countries over the last several decades. In some cases, it takes several times more land to convert to “humane” methods.

So while the immediate surroundings of smaller scale pasture-based farm operations may have less concentrated pollution and less soil erosion than that produced by large-scale industrialized farms, the reality is that vastly more high quality farmland would be needed to convert existing production to “humane” farming. That amount of land is simply not available on the scale needed to meet the rapidly growing worldwide demand for animal products. It is also important to realize that as more wild lands are converted into “humane” farm land, more and more free-living animals will be displaced or killed, and more species will be driven to extinction.

So, when we step back and take a wider view of what is happening on our planet now, and what is projected to come to pass if we keep living the way we are, we’re obligated to consider our individual responsibility. Wouldn’t it be great if each took steps toward living in a way such that if everyone on the planet lived as we were, human civilization would be sustainable?

The reality is that moving toward consumption of “humane” animal products does not meet this standard. Instead, it is a time and resource-wasting distraction, one we can ill afford in the midst of an unprecedented ecological crisis.

If we wish to preserve our environment, avoid endless wars over energy and water, and if we do not wish to obtain our prosperity at the expense of the exploitation of others, if we wish to do right by those of future generations, the time has come to re-evaluate the role animal-agriculture plays not just in our own personal lives, but as a root cause of a number of planetary ills.

***

The ecological problems of meat production don’t just stem from factory farms. They stem from animal agriculture in general. The demand for meat products in a world of 7 billion humans generally cannot be met in a “sustainable” way. Likewise, the mass exploitation of animals does not just stem from factory farms. There is no animal agriculture that does not, at worst, massively abuse animals and, at best, manipulate their bodies and reproductive systems as instruments and unnecessarily kill them.

Vegetarian Myth corrections from Vegans for Sustainable Agriculture

July 25, 2010

Vegans for Sustainable Agriculture are doing great work and have put out this useful pdf. You can download it here and pass it out if you want. Thanks, Vegans for Sustainable Agriculture!

The Vegetarian Myth by Lierre Keith Corrections to Some of the Many Errors and Misconceptions

The Claim: Lierre claims that grazed animal farming/polyculture can feed nine people per ten acres. (P. 101)

In Reality: Lierre lists the food produced on a 10 acre perennial polyculture. Her numbers are based on Michael Pollan’s exposition of Joel Salatin’s Polyface Farm in The Omnivore’s Dilemma, and are arrived at by dividing the numbers for Salatin’s 100 acres of grass by 10. But Pollan explains at great length (P. 222-225) that the 100 acres of grass is really 550 acres because the adjacent 450 acres of forest are essential to the health of the farm. Accordingly, ten acres of land actually feed about two people rather than her estimate of nine. Lierre says that if you live in New England you should eat what grows there. However, with this level of productivity, you couldn’t feed all of New England on all the land in New England.

The Claim: “I built my whole identity on the idea that my life did not require death…Did the lives of nematodes and fungi matter? Why not? Because they were too small for me to see?” (P. 18, discussed throughout the book)

In Reality: This is a straw man argument. These views are not held by most vegans. The goal of veganism is to eliminate direct, unnecessary suffering at the hands of humans — not to magically end all death. Why shouldn’t the cow with its undeniable ability to suffer take precedence over plants and organisms with limited or non-existent nervous systems such as the nematodes Keith frets about in this book?

The Claim: Lierre claims that sustainable farming is not possible without domesticated livestock. “I would need domesticated animals—their labor and the products of their bodies—to farm sustainably. I needed their manure and their unspeakable bones, their inconceivable blood.” (P. 58)

In Reality: How then does she explain the success of vegan organic agriculture in the UK and US, where no animal inputs are used? How does she explain that the most successful organic CSA in the country actually uses no animal products on their fields (Honey Brook Farm in New Jersey)?

The Claim: “Understand: agriculture was the beginning of global warming. Ten thousand years of destroying the carbon sinks of perennial polycultures has added almost as much carbon to the atmosphere as industrialization, an indictment that you, vegetarians, need to answer. No one has told you this before, but that is what your food—those oh so eco-peaceful grains and beans—has done.” (P. 250)

The Reality: Much of Lierre’s book is borrowed from Richard Manning, a well-respected environmentalist and author. Manning understands that human dependence on grain monoculture is not a result of the small percentage of concerned people who decide to be vegetarian, but is rather a historical mistake of which we all share the burden of repairing. Despite Lierre’s insistence, vegans do not need to eat grains nor any sort of annual crop. Why did she target vegans when compared to average corn-fed Americans, vegans consume much less grain? On the topic of climate change, Lierre fails to address that regardless of type of feed or forage, ruminant animals emit an abundance of methane. She, along with other grass-fed proponents, point out that growing pasture sequesters carbon in the subsoil and claim that farms like Polyface are carbon-neutral. However, she ignores the fact that soil only retains a limited quantity of carbon—once pasture is healthy, it is carbon stable. Any pasture-based livestock production contributes, pound-for-pound of meat, to climate change as much (if not more) than conventional livestock production—an indictment that you, Lierre, need to answer.

The Claim: “We’ve been doing what we’ve been endlessly badgered to do since the 1960s. We’ve eaten, according to the USDA, less fat, less meat, fewer eggs. Our dietary fat has fallen 10 percent, hypertension has dropped 40 percent and the number of us with chronically high cholesterol has declined 28 percent.” (P. 203)

In Reality: Americans eat more meat now than in the 1960s according to the USDA (http://tinyurl.com/USDAstats1). While the average percentage of calories from dietary fat consumption has decreased, dietary fat intake increased from 135 g to 178 g from 1960 to 2006 (http://tinyurl.com/USDAstats2).

The Claim: “We owe our bodies what we owe the world; we must inhabit both and, in the act of inhabiting, nourish both. This food must also be an apology for what my kind has done, and part of the repair. It must protect this land, and extract from me the promise of more. My food is those things, all of them. It’s based on the forests and grasses that nestle this planet in soil and air.” (P. 271)

In Reality: Lierre’s own blog posts demonstrate that she can’t stick to her own ideals. She has posted entries where she raves about the perfection of grain-fed pork and happily offers a bucket of mass-produced, processed chocolate laden with factory-farmed dairy to trick-or-treaters last Halloween. If this is what she’ll post on her own blog, what other unsustainable foods is she eating? (http://tinyurl.com/lierre1, http://tinyurl.com/lierre2)

The Claim: “…there are no good plant sources of tryptophan. On top of that, all the tryptophan in the world won’t do you any good without saturated fat.” And later Keith blames the lack of tryptophan in vegetarian diets for depression, insomnia, panic, anger, bulimia and chemical dependency. (P. 10)

In Reality: A cup of roasted soybeans contains nearly three times the adult RDA of tryptophan and a cup of pretty much any other bean will get you between 50-60% of the RDA. Two tablespoons of coconut oil more than meet the adult saturated fat RDA. Nuts, dark chocolate and avocado are all rich in saturated fat.

The Claim: “Sixty grams of soy protein—that’s one cup of soy milk—contains 45 mg of isoflavones.” (P. 215)

In Reality: The soy milks available in supermarkets have about 6 to 11 grams of soy protein per cup. According to Lierre’s often-cited Weston A. Price Foundation, a cup of soy milk contains only 20 mg of isoflavones.

The Claim: “I am of this world, carbon and breath like my parents, my siblings, the creatures great and small, single-celled or green, that create the miracle the rest of us consume. They gave me this body and the air it needs, the food it eats. All they ask is that I take my place, a predator, dependent and beholden, until I am prey.” (p. 271)

In Reality: The animals humans consume are quite literally prey, but unless Keith intends to be eaten by a wild animal, her claim of being “prey” is a specious one based on her decomposition. She considers this a repayment to the biosphere for its kindness in feeding her, but that same repayment is unacceptable from edible animals.

The Claim: Lierre claims that “Researchers from Cornell showed that E. Coli 0157:H7 could be stopped by a very simple action: feeding cows hay for the last five days of their lives.” (P. 99)

In Reality: In the study Lierre refers to, the researchers showed that overall E. Coli levels (i.e. including strains other than 0157:H7) in three cows were decreased by feeding the cows hay for five days. They conjectured that 0157:H7 levels would be similar. However, subsequent research suggests that grass-fed beef does not have lower levels of 0157:H7 (http://www.slate.com/id/2242290/pagenum/all/).

The Claim: “The pursuit of a just, sustainable, and local economy will eventually lead us to the grim conclusion that there are simply too many of us. The world population is supposed to reach 8.9 billion by 2050. Meanwhile the oceans will be fished empty by 2050, the aquifers and water tables will be well out of reach, and the last trace of topsoil rendered dust. We are already living on fossil fuel and this—right now—is the historical moment when oil will peak. It will never be this cheap or accessible again. What then?” (P. 120)

Counterpoint: Keith has no answer to “What then?” The only answer one can deduce from the book is that she advocates nothing short of the elimination of agriculture and civilization and a drastic reduction of population to some level that she considers sustainable. Simultaneously, she believes that civilization’s doom (and consequently, an enormous loss of human life) will soon be upon us, so maybe it makes sense that her ideas are not solutions. The only thing worth taking from The Vegetarian Myth is the idea that the simple act of going vegan automatically solves all problems with our food production. That said, it is still the easiest and most substantial immediate action a person can take on the path to a sustainable lifestyle. True, some vegans and organizations do exaggerate the ecological benefits of eating highly processed, conventionally-grown vegan food; however, a balanced plant-based diet of mixed perennial and annual fruits, vegetables, nuts and legumes is far more sustainable than any diet based on ruminant, energy-hungry, greenhouse-gas emitting livestock.
