A Note To Rachel Carson On The 50th Anniversary Of “Silent Spring”

What looks like it might be an original copy from 1962
Dear Ms. Carson,

On this, the 50th anniversary of the publication of your book, “Silent Spring” I’d like to tell you about the remarkable legacy of your book.  Many things have transpired over the last five decades that would give you considerable satisfaction. Unfortunately, I must also explain to you why many people today don’t understand how profound those changes have been.

Your Positive Legacy

The biggest change since 1962 has been in our societal appreciation of the need to carefully evaluate the environmental and health attributes of chemicals that we use for the control of agricultural pests or the vectors of human disease.  Whole new fields of science have developed to understand such risks (environmental toxicology, environmental science to name two).  Whole new regulatory bodies (Environmental Protection Agency, EPA) and processes (chemical registration) have been instituted to translate those risk assessments into sound policy.  DDT, which was central to your 1962 warning, is long-gone, as are scores of other, old pesticides that cannot meet high, modern, safety standards.  Billions of dollars have been invested in the discovery, testing, and introduction of new, low-risk pest control methods and practices. The net effect of all of this is that not only are our springs well-accompanied with bird songs, we also enjoy a safe, affordable and diverse food supply beyond anything one could have imagined in 1962.  I’m sure that when you took the risk of publishing your book, you hoped that it would initiate this sort of positive change, and that is certainly what has happened.

Your Legacy Obscured

Unfortunately, there are some today who seem to have a vested interest in convincing us that your legacy has not been this positive. Whether it is to sell certain products or to garner attention or contributions, these voices continue to promote a “sky is falling” narrative. When you wrote 'Silent Spring,' you employed highly emotive language, vivid mental images, and a good degree of hyperbole.  Such over-the-top prose was justifiable because you had to overcome the deep-seated complacency of your age. Today, many groups continue to employ that same literary style when talking about food and agriculture issues.  By doing so, and by engendering unnecessary fear among consumers, they effectively deny people the confident enjoyment of life and food that would otherwise have been another part of your legacy. I am confident that you hoped to initiate change, not to inaugurate a perennial state of alarm.

A Prime Example of Your Positive Legacy

Each year the USDA conducts an extensive sampling and testing program for the American food supply.  It essentially serves as a “report card” for agricultural pesticide safety, both in the US and in countries from which we import foods.  What the report clearly shows is that consumers have no need to be concerned about pesticide residues on their food.  The extremely low levels detected are virtually all well below even the conservative tolerances set by the EPA and mostly millions of times below toxic doses.  These results speak volumes about the positive impact of your book. 

A Prime Example of Your Positive Legacy Denied

There is an organization called the Environmental Working Group (EWG), which takes that same set of data and quite effectively uses it to frighten consumers.  They do so by ignoring almost all the actual information in the USDA report.  They ignore that differences between chemicals as if we had learned nothing about what to look for in 50 years.  They ignore the actual levels detected as if we have forgotten the ancient Greek understanding that "the dose makes the poison."  Finally, they ignore the carefully set EPA tolerances as if over all these years, we have learned nothing about how to evaluate risk.  Unfortunately, their message is widely disseminated by a credulous press and believed by a great many consumers.

Real Environmentalism

Your book is widely credited as a major contribution to the development of the modern Environmental Movement.  That is, indeed, a very positive result of your influence. A strong segment of that environmental movement continues to make significant contributions to society.  That part of the movement acknowledges that there has been positive change that you helped to initiate and to which many entities have contributed over the years.  The segment of the Environmental Movement that effectively denies positive change does no service to your legacy.

Consumers Should Get To Try The First Biotech Apples

There are some unique apples that could be coming to the market in the near future.  They will taste exactly like some familiar varieties, but their distinguishing feature will be that they won’t turn brown after they are sliced.  Scientists employed by a grower-owned fruit cooperative in British Columbia used genetic engineering techniques to turn off the genes for the enzymes that cause cut apples to turn brown (polyphenol oxidases).  These non-browning apples will be offered under the "Arctic Apple" brand.  Unfortunately, there are some groups who are actively trying to block this effort.  Let’s consider why consumers should get the chance to try these new apples.

A Real, Consumer-oriented Trait

Many have complained that biotech crops only benefit farmers, not consumers.  That is a false dichotomy.  When crops are more productive, easier to grow, or entail less risk for farmers that produce them, consumers get the benefits of a low cost, dependable food supply.  Still, it is refreshing to see a trait that is designed completely with consumers in mind.
Folks like Andrew Kimball of the Center for Food Safety, who routinely oppose all biotech crops,  have used their standard approach of coining a catchy, disparaging term.  They call these, "Botox Apples" with the implication that this is something with only a cosmetic purpose.  This entirely misses the point.  The appearance of food is extremely important to the enjoyable, multi-sense experience of eating (taste, smell, mouth feel and appearance).  Browning apples are not appealing. They also don’t taste so great.  Yes, you can treat cut apples with lemon juice, but that changes the flavor.  An apple that can be sliced and not quickly brown could be used in packaged salads, on salad bars, in packed lunches and in many other settings where this popular fruit is not used today.  It would be nice to be able to eat part of an apple and then finish it later.  Browning is not a "cosmetic”  issue. It is a consumer convenience and eating experience issue.  We should get to see if we like it.

How These Apples Stand Vs Other Standard GMO Crop Objections

Big Companies: This apple was developed without any involvement from “big companies.”  A private company mostly owned by fruit growers very frugally and patiently funded this research for many years.
"Foreign Genes:" There are no "foreign genes" in Arctic Apples.  All that is different about them is that certain apple genes are "turned off."  Most genes in cells of an apple or any other organism are turned off most of the time.  The genes to grow roots or leaves are turned off in apple fruits just as our genes to develop the features of an eye are turned off in all the other parts of our body.  The scientists that developed the Arctic Apple simply used a natural mechanism to turn off the genes that make the enzymes that turn apples brown when they are cut.
Labeling: Some people are concerned about unlabeled GMOs.  It is actually quite easy to know and even to avoid GMO foods if someone is so inclined, but in this case, the apples will be explicitly branded as GMO. In an industry like apples, "identity preservation" is a completely feasible and normal practice (there is a PLU sticker on every fruit or at least on every clamshell).  Those who want to try the Arctic apples can easily do so, and those who don't can easily make other choices.
What About Organic Growers? Could these apples “contaminate” organic apples and threaten their certification?  Not unless someone works really hard to do that.  Apple trees are not grown from seeds (like virtually all fruits).  If you plant the seed from your favorite apple (say a 'Fuji'), the tree you will grow will not be a Fuji.  It probably won't even have decent eating apples.  For thousand of years, people have known that if you find a fruit that is good, you need to propagate it from cuttings or buds, not seeds.  These are grafted onto rootstocks that have been selected for pest resistance and in most cases for dwarfing so the trees don't get too tall to safely pick.  Actually, to get a good crop, growers need to make sure that the bees that visit each tree have typically gotten pollen from some other variety of apples, even crab apples, because otherwise fruit set is less likely.
There is a small chance that a bee will carry pollen from a GMO apple to a few flowers in an organic block.  A few of the seeds in those organic apples might be pollinated with the GMO pollen.  Only a small part of the seeds (the embryo) in those apples will have that extremely minor change.  Apple seeds shouldn't be eaten.  They contain compounds that can generate cyanide - a rather potent poison.  Consumers routinely discard them.  Only if someone really, really wanted to, could they even document the "contamination."
Organic has always had the rule that if unapproved pesticide residues were found on organic crops, they would still be certified organic as long as it was unintentional on the part of the grower (e.g. spray drift).  The organic certification system never actually tests for this, but the precedent is clear.  If it is minor and unintentional is isn’t an issue even for produce you eat after paying the organic premium.  Why would this be different for a silenced gene that only has a context in ripe fruit, that is present in a rare apple seed embryo in a seed that is logically discarded?

Who Is Opposed To The Commercialization of the Arctic Apple?

A predictable list of anti-GMO groups like the Center for Food Safety are opposed to these apples. This time they have had to reach for objections, but their stance is no surprise.  What is not entirely surprising, but disturbing, is that there is opposition from groups of regular apple growers.  I've worked with the apple industry on many occasions over the past two decades, and I have a great deal of respect for these folks.  I can understand what is behind their reaction, but I would like to challenge these friends to step back and think about the ramifications of their swift, negative reaction.

Brand Protection

Technology opponents have long known that they have the most leverage if they can threaten an entity with a valuable consumer brand with potential, controversial attention.  The apple industry is concerned that even though the Arctic apples would be clearly labeled as such, activists could smear the entire apple industry “brand” and make consumers afraid that they might be eating something the don’t want.  (Would activists seek to threaten the livelihood of uninvolved farmers to achieve their goals?  Absolutely.)

Remembering the "Alar Controversy"

There is certainly history behind “brand” concern by apple growers and marketers.  Back in 1989, an edition of the popular news show, "60 Minutes" raised concerns about a purported carcinogen that was being sprayed on apples and which was disproportionately represented in children's diets because they drink lots of apple juice.  The science behind the carcinogen issue turned out to be completely bogus, but that didn't prevent a huge decline in consumer consumption of apples.  I'm sure there are plenty of folks left in the apple industry who remember the lesson that truth isn't any sort of certain protection against "brand damage" by disinformation.

What is The Apple "Brand?"

The apple industries of various states, provinces and regions have spent a fair amount on "brand building", but a general rule in the industry is that produce brands are really difficult to build. Think about apples and all the history behind that name!  The forbidden fruit in the Adam and Eve story has been, inaccurately, pictured as an apple.  The witch in the classic, Disney-enshrined story of Snow White used a poison apple.  This fruit has been commandeered as the symbol of a rather successful computing technology brand.  We have common sayings like "one bad apple spoils the whole bunch, " or "an apple a day keeps the doctor away."  The nature of the apple “brand” is something far beyond the marketing power of some farmers in BC.

A Marketing Lesson Not To Be Forgotten

There was a time, before the Alar scare, when the apple industry believed that it was competing with bananas and oranges for "share of stomach."  Apples were one of the few crops that were available in fresh form year-round.  The industry tried to define the "apple brand" as a Red Delicious of a given shape.  That whole strategy crashed in the Alar scare. Grower/shippers then broke out of that mold and market different apple varieties by name (Granny's, Fujis, Pink Lady's, Jazz, Jonagolds…).  What the industry and the retailers learned is that consumers are perfectly capable of deciding what they like and don’t like, and selecting it by name.  I would argue that this is the same thing that could happen with the Arctic apple if consumers are given the chance to try it.

A Plea To My Friends In The Apple Business

I almost never oppose grower opinion.  I remember Alar as vividly as many of you do.  I've seen what anti-GMO activists have been able to achieve in many instances.  I know it is a burden to be the first US/Canada crop where a new biotech option could be launched for consumers by growers.  It is never fun to be the pioneers.  But if you step back and think about how much of your industry depends on technology that consumers might not understand, is it good idea to give anti-science activists an easy win?

You Can Voice Your Opinion

The public comment period is now open to let the USDA know what you think.  They are already getting lots of comments from people who understand very little about these apples.  It would be great to balance that with more informed responses.  You can read more about this topic over on Biofortified.

Full disclosure.  I have no economic connections with the folks behind the Arctic apple.  I’d just like to see their product reach the consumer market.

Limited Encouragement In The Latest Release of the FAO, Global Food Price Index

Today, the Food and Agriculture Organization (FAO) of the United Nations released it's monthly update on global food trade pricing.  The overall "Food Price Index" that combines all categories did decline slightly, but less than the previous month.  The index is still substantially higher than it was at a comparable period during the last cycle.

During June, the Cereal price index remained essentially flat, mirroring the trend from the previous cycle but at a new higher level.  There had been hopes that record grain planting for the 2012, US growing season would help to increase stores this fall and lead to significant price drops.  A troubling and spreading drought is developing in the American Midwest.  Without some timely rainfall during the key period of corn pollination there could be significant crop loss.  This possibility is  already leading to price increases for current and future US grains.  It is impossible to know yet whether this drought, and all the other weather extremes of this year, are the result of Climate Change.  Many climate experts believe that it is.

Meat prices increased dramatically in this cycle compared to the last one.  This is driven by increased demand from the huge new middle class populations in countries like China and India.  Meat prices are also linked to grain prices so it is no surprise that they remain unusually high.

Dairy prices, which had shown two months of significant decline, continued to drop, but at a slower rate.

Oils were down for June, but that has only just now reversed an upward trend that began seven months ago.

Sugar prices are not really linked to the same trends as the other commodities because tropical sugarcane production is less seasonal and much less tied to yearly planting decisions.

The Data Still Suggests That We Are In A New Food Supply Paradigm

Last year at this time, I began pondering whether this second, unprecedented spike meant that the global food supply has entered a new paradigm.  For decades price cycles fit that old saying: "The best remedy for high food commodity prices is high food commodity prices."  That meant that when prices went up, farmers would farm more or more intensively and inevitably produce enough new supply to bring the prices back down.  Farmers still respond the same way, but the effect of their efforts to produce more is having less impact.  Part of that is that global demand is higher than ever based both on population and standard of living.  Biofuels are a new part of the equation.  I also believe that we will be able to look back in a decade or two and say that Climate Change is indeed behind the heat, droughts, floods and pest increases that keep limiting production.  That is why I have argued that the "face of climate change" should not be polar bears.  It should be the poor families around the world that depend on global food trade and for whom these stubbornly high prices are a serious burden.
