There is a lot of confusion and disinformation circulating today about seeds and the ethics of their commercial sale.  Actually a healthy, commercial seed industry is critical for agricultural sustainability.  Because seeds are such a fundamental component of the sustainability of our food supply, this area deserves careful thought and accurate information even if you are never going to farm or even garden. I’ll try to address some of the modern “myths” about this.  I’ll talk about “farmer-saved seed,” and “hybrid seed.” In a later post I’ll talk about “GMO seed,” and the mythical “Terminator Technology.”  But first a little history.

Seed-bearing plants start showing up in the fossil record ~350 million years ago, first as gymnosperms like cycads, conifers… and eventually, flowering plants (angiosperms) like most of the living plants today.  Other than pine nuts and sea weed, I can’t think of any crops that are not angiosperms (Contest! - 5 virtual sustainability points to someone who can come up with another non-angiosperm crop plant)

Jarrod Diamond’s wonderful book, “Guns, Germs and Steel” talks about how the initially accidental and later intentional collection and planting of seeds is what made human civilization possible - the move beyond the hunter/gatherer state that happened about 10,000 years ago in the “fertile crescent.”

Have trouble getting up early on Saturday morning to get to the farmers market? Yeah, me too. And while more supermarkets are featuring more selections of local food on their shelves and in their stalls, there’s nothing quite like that straight-from-the-farm produce. What’s a late sleeper to do?

A new web service, Local Dirt, is out to make the connection between the local farmer and buyer more convenient. Say you’re looking for local peaches during the season. Local Dirt’s interface allows you to set search criteria based on location, product, and even venue (if you choose), and find a farmer from whom you can buy online. Sleep in on Saturday, get to the market late, and your peaches are still there… the service provides you with a purchase order to take to the vendor. Some of the farmers may even deliver…

From the comment streams and emails I’ve been getting about recent posts, it is clear that many people believe things that are not actually true about the environmental profile of organic fertilizers.  I don’t mean to minimize the challenge we face when it comes to fertilizers, particularly nitrogen fertilizers.  They take energy to make, have the potential to generate the potent greenhouse gas, nitrous oxide, and can lead to the pollution of ground and surface waters.  With a “rap-sheet” like that I understand why people are concerned, but there is a catch - without fertilizers we don’t eat much.

Still, there is a widespread belief that “Organic” fertilizers are the solution.  I’ve already blogged about why organic fertilizers are dramatically worse from a greenhouse gas point of view.  Today I want to talk about the water pollution issues and why “Organic” fertilizers are actually a much worse problem from that perspective as well.

Why Nitrogen Fertilizers Can Pollute

The reason that ALL nitrogen fertilizers (synthetic and Organic) are a water pollution threat is that they at some point convert to the nitrate ion (NO3-).  That particular form of nitrogen is very water soluble so the nitrate can move down into ground water or sideways into surface water.  The “Dead Zone” or “Hypoxia zone” in the Gulf of Mexico is driven in some large part by nitrate coming from farms.   There are ways to manage this issue, but first I need to talk about the fundemental challenge of crop fertilization.

I’m probably going to irritate some people with this post.  I apologize in advance because that is not at all my intention.  For those readers that don’t think climate change is a real problem, I respect the fact that there is uncertainty in that science, but if the majority position of climate scientists is true, the stakes in terms of human suffering among the poor are too high not to act.  For those who think Organic farming is the answer, I’m not trying to argue the whole issue here - I just want to talk about the science associated with climate change and farming.  I have spent months reading the scientific literature on this topic.  That science points to some very specific changes in how we need to farm.  If those changes were compatible with Organic I’d be a big promoter.  The short answer is “Organic farming is not the best option from a climate change point of view.”

I know this sounds like heresy in the “Green Blogosphere,” but before you react, please read on.  I agree in advance that the Organic/non-Organic discussion is much broader than climate change.  In fairness, climate change was never something that “Organic” was designed to address either during its origins in the early 20th century or during the development of the USDA Organic rules between 1990 and 2000.  I have no desire to get in the way of Organic growers making a living (including my good friends who grow Organic of the old school category) or get in the way of Organic customers getting what they want.    I simply believe that it is critical that we, the declining subset of people who take climate change seriously, be accurately informed about this issue.  If we believe we “have the answer” for farming when that answer is wrong, that keeps us from continuing to find the real answer.

Focusing on the Major Crops

Because it would be far too complex to discuss this question for all crops,  I’ll only be talking about the “carbon footprint” of the major row crops (see the pie chart above) - the wheat, corn, hay, barley, oats, corn, soybeans, hay, oats, dry beans, lentils… that make up the bulk of our calorie intake, our vegetable protein intake, and our animal feeds for meat and dairy.  Those crops also make up the vast majority of farmed land, so they are what matters for climate change.  Fruit and vegetable crops are extremely important for health and food enjoyment, but not much for climate change.  Organic today is heavily weighted to the fruit and vegetable segment and beyond that, it is extremely small. Actually, all of Organic only represents 2.6MM acres ( ~0.7%  of US cropland), so it has almost no effect on climate either way. This is only a discussion about the widely held opinion that Organic would help in a climate change sense.

Editor’s note: This review is part of the Green Books campaign. Today 100 bloggers are reviewing 100 great books printed in an environmentally-friendly way. Our goal is to encourage publishers to get greener and readers to take the environment into consideration when purchasing books. This campaign is organized by Eco-Libris, a a green company working to green up the book industry by promoting the adoption of green practices, balancing out books by planting trees, and supporting green books. A full list of participating blogs and links to their reviews is available on the Eco-Libris website.

Thinking about giving gardening a try? While the traditional growing season has ended in most parts of the US for this year, it’s not too early to start planning for next Spring. You may want to check out books on starting a backyard garden, and there are plenty of them out there. You may also want to find some of the books that offer suggestions and recipes for the produce you grow. And, if you need encouragement to grow organically, there are still more books on that subject.

If you want a book that covers all three of those areas, though, your choices get much more limited. Janette Haase’s From Seed to Table: A Practical Guide to Eating and Growing Green* not only provides readers with gardening instructions and tips, recipes and menus, and essays on the environmental issues surrounding agriculture and food production, but does so in a month-by-month structure that gives you the information you need when you need it.

In the comment streams on my blog posts there is a recurrent theme from one segment of the respondents - they have a deep distrust in the large companies that are involved in modern agricultural technology.  They don’t believe these companies will behave ethically because they are for profit entities “only answerable to their shareholders.”   

I’d like to speak directly to this as a long-time Ag industry insider whose experience does not support these suspicions. I know that some will dismiss this perspective assuming I am biased, but one has to balance potential for bias with actually having first-hand experience from which to speak.  Over the last 32 years I’ve work for or with most of the companies, large and small, that provide agricultural technologies.  Fourteen of those years have been as an independent consultant so I get to know what is going on inside of many companies in a given year.  I have still only had direct knowledge of a subset of what happens, but in all of that exposure I’ve never witnessed an unethical decision or action - not even the consideration of one.  I’ve seen certain decisions that were short-sighted.  I’ve sometimes seen decision-making processes that are more driven by fear than by opportunity.  I’ve seen missed opportunities because vision was lacking.  I’ve occasionally seen failures to take advantage of synergies that could have been realized between divisions of large organizations. I’ve seen problems, but I believe that some level of dysfunction is inevitable in any organization involving people.  Still, unethical behavior isn’t something I’ve seen so I disagree that it is automatically likely just because of the characteristics of the company.  

On balance I’ve also seen these organizations, large and small, frequently make important contributions to society in terms of the productivity and safety of our food supply.  I’ve seen these companies continue to do that in an environment of constant activist attack and very limited public understanding because so few people farm.

Last Monday the popular show “CSI: Miami” ran a segment in which a young woman dies and it turns out to be because of a GMO corn developed by a rogue company called “Bixton Organic Foods.”  In the plot, the company willingly puts people at risk.  This fictional scenario bears no plausible tie to reality, but it fits well with the simplistic, good guys/bad guys image in the Myth that many people believe about farming.  To see how it feels to be the brunt of a distortion like this, I recommend you read a post from a real corn farmer.  

So why is it possible for CBS writers to generate fictional “drama” about the “danger of GMO” when in fact GMO technology has been used with complete safety for more than a decade on a gigantic scale?  (Having witnessed first-hand the thought and care that went into developing this technology over the past 30 years, I’m not surprised by that safety record).  There is an abundance of good information available about this technology including many confirmations of its safety by panel after panel of highly qualified, science and medical experts around the world.  I think the reason that the fear of GMO persists in certain extreme circles is the same reason that there are still “birthers” and people who are sure that health reform will lead to “death panels.”  Its not that there is much overlap between these demographics but rather that the same mechanism of “selective knowing” is involved.

Around 1300 c.e. the Yao and Zhuang people of Guangdong Province in Southern China faced a serious problem.  In the Longsheng area there was a growing population, but their mountainous surroundings gave them very little land that could be used for farming.  They needed more food and so they turned to technology for the solution.  What they did was to terrace their mountainsides even up to slopes of 45%. I’m sure that the method was perfected over the 400 years of building.  What they were able to do is still an impressive example of civil engineering, even today.  Using stones and mud they built terrace walls that stand firm even with the torrential downpours that are common in the area.  They used bamboo piping to distribute water to each paddy - some so narrow that they only have room for two rows of rice.  This production system has remained productive for centuries when many other contemporary farming societies around the world simply depleted one area and moved on to the next.  These terraces are called Longji, or the ”Dragon’s Spine” and they now extend over 66 square kilometers.  They are both beautiful and inspiring.

School lunches are a social justice issue for children in our country today. Sugar is our nation’s biggest addiction, after oil.

And sugar, coupled with poor nutrition, is just as debilitating. A poor diet, one that is preservative rich and nutrient poor, causes kids to feel sluggish, perform poorly and addles their brains. This is referred to as the “achievement gap” because it generally affects children of lower-income households.
