“Food Miles and the Relative Climate Impact of Food Choices in the United States”

April 20, 2011

This study is a must-read for anyone concerned with food politics. It’s one of the only studies done on the issue. Abstract and full text are available here: Food Miles and the Relative Climate Impact of Food Choices in the United States

For those not into the technical language of scientific articles, here are the basic findings:

1) Food miles are not an accurate way to measure a food’s ecological footprint. Transportation of food accounts for only about 15 percent of its ecological footprint.

2)Production, storage, whether a food is animal or plant, non-carbon greenhouse gas emissions, scale, and other factors account for about 83 percent.

3) An accurate picture of a food’s environmental impact needs to include all those aspects and that can be done much more throroughly with a life cycle assessment (LCA). Movements for ecological sustainability would fare much better if they used the LCA instead of the food miles model.

4) It is impossible to do an all-encompassing study on the climate impact of food. This study is based on the “average” US household. Unmeasurable factors might play a role in many situations. Despite, these findings point to critical issues regarding diet and ecology.

5.) For the average household, eating vegan food one day a week achieves more of a reduction in environmental degredation than eating local animal products every day. Or, more precisely: “The results of this analysis show that for the average American household, ‘buying local’ could achieve, at maximum, around a 4−5% reduction in GHG emissions due to large sources of both CO2 and non-CO2 emissions in the production of food. Shifting less than 1 day per week’s (i.e., 1/7 of total calories) consumption of red meat and/or dairy to other protein sources or a vegetable-based diet could have the same climate impact as buying all household food from local providers.”

I look forward to more work being done on this, and more conversation being had.


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.


Introducing the Carnism Awareness and Action Network

December 4, 2010

We are excited that CAAN: Carnism Awareness and Action Network has kickstarted. This is a great resource for vegan advocates and meat eaters alike, dedicated to naming the invisible paradigm that allows well-meaning people–people who have other choices–to choose to eat some animals and not others.

CAAN’s mission statement:

CAAN’s mission is to expose and transform carnism, the invisible belief system that conditions people to eat certain animals. CAAN empowers vegetarian and vegan advocates and concerned citizens through education and activism.

Accordingly, CAAN espouses the following beliefs and principles:

  • The production and consumption of animal products is the leading cause of animal exploitation and environmental degradation and a major contributor to human disease, human rights violations, and unjust taxation via animal agriculture subsidies. We therefore believe that carnism poses a direct threat to both animal and public welfare and must be addressed with urgency.
  • We believe that most people care about animals and do not want to cause them unnecessary harm; therefore, when people choose to eat animals they act against their own interests, as they must violate their core values.
  • Because it is impossible to objectively discuss the issue of eating animals as long as we are operating from within the system – unaware of the structure and effects of carnism – we believe that it is necessary to expose carnism in order to have a valid public dialogue about the legitimacy of animal agriculture.
  • Because carnism is organized around violence and deception, we believe that transforming the system is essential for creating a just, sustainable, and democratic society.
  • Carnism is a system of victimization that exploits carnists and pits carnists and vegetarians against one another. We believe that carnists and vegetarians must unite in order to transform the system.
  • We recognize that many people, such as those who are economically disadvantaged or geographically dependent on eating animals, do not have the luxury of reflecting on their food choices.
  • We acknowledge that carnism is one of many systems of interlocking oppressions and that social transformation requires a broad social analysis.
  • We are committed to total nonviolence, in action and attitude. CAAN does not endorse physical violence or degrading language.
  • We believe that the time is ripe to challenge carnism and that with enough public support we can, and will, transform the system.

Welcome to the Myths about “The Vegetarian Myth” blog

July 5, 2010

We’ve started this blog because we are concerned by what we consider to be an abundance of misinformation, sketchy research, and logical fallacy found in the somewhat popular book, The Vegetarian Myth by Lierre Keith.

The Vegetarian Myth was published on Derrick Jensen’s Flashpoint Press. Derrick Jensen is Keith’s guru/teacher, and a pretty well-regarded anti-civilization theorist who has a notable following. On the cover he has blurbed himself as saying, “This book saved my life.” In the publishing world, it is considered big-time intellectual dishonesty for a self-interested publisher to write a blurb– especially one like this– for his own book. This is not to be taken lightly, as he stands to gain in money and popularity if the books does well. So from the very front cover, this book is permeated with an instance of intellectual dishonesty of a type that is not to be taken lightly.

Throughout this blog, we will be deconstructing the book by chapters and themes, in order to give some perspective, as well as offer what we consider some vitally important alternatives to Keith’s ideas.

Please check back, as we will begin our postings soon. Thanks!
