Earlier
this month a handful of scientists and doctors hailing primarily from Stanford
University published an article about the health benefits of organically grown
food. What they found was quite controversial: that organically grown foods are
not any safer or healthier than conventionally grown foods.
The
response to this article has been substantial. Organic interests have quickly
replied that the study fails to address many issues that make organic
agriculture so necessary and important. Some of these arguments are thoughtful.
Others are simply ridiculous – and amusing. All of them that I have read,
however, fail to take a broader look at the organic movement and appreciate the
reality of the world we currently inhabit.
Take
the pesticide issue as a case in point. This is the main issue (of any
credibility) that the organic apologists make against the Stanford study. It is
argued that conventionally grown crops contain pesticide residues that are not
found on organically grown crops. This is true for the most part. But this
claim needs to be considered along with the fact that the residues occurring on
non-organic produce fall below the danger zone established by EPA and FDA. They
have to. It’s the law.
Well
yes, argues the organic lobby, but what about the long-term effects of these pesticide
residues? Certainly they can’t be healthy.
And
the answer to this troubling question is that we don’t know for sure? And this
is my point. Arguing about the dangers of miniscule amounts of chemicals on
food makes about as much sense as arguing about the quality of the air we
breathe. And I don’t mean this as an analogy. The air we breathe is probably just
as dangerous to our long-term health as anything on the skin of unwashed apples.
It may be more dangerous in some instances.
I
don’t mean to poke fun at the organic movement. I would be a hypocrite to do
so. But for a long time now, the purveyors of the organic gospel have been pushing
an agenda that is quite different from the way their own movement got started. Special
interests in recent years have focused on the evils of big business – the big chemical
business in particular – whereas originally, the organic movement focused on
the health of the soil.
Sir
Albert Howard is generally recognized as the father of organic agriculture. His
book, An Agricultural Testament,
published in 1943, is a clear statement on the importance of composting to good
health. Howard was an agricultural adviser in India during the early part of
the 20th Century and faced the challenging problem of low soil
fertility in a land that did not use cow manure in agriculture (manure was/is
used as a fuel for cooking and heating homes). His solution was to use
so-called “green manure” or decomposing plant material to add fertility to impoverished
soils.
Howard
named his composting method the Indore Process, after the village where he worked.
It was a great success and became the basis for many books and articles
published by J.I. Rodale (via Rodale Books and the Rodale Press).
Some
of this early literature does address the importance of limiting the inputs of
chemical fertilizers and pesticides, but these issues seem to be mere tangents.
The clear message is that healthy soils produce healthy food; which, in turn,
produces healthy people.
Then
the environmental movement came along. And after Rachel Carson’s Silent Spring, many things changed
within the organic movement. Pesticides became the causa belli. During the decades following the 1960’s many
pesticides were banned and the Environmental Protection Agency became a
powerful organization deciding what could and could not be used to protect the
nation’s food from pests. The widely active biocides and pesticides with long
residual activity were the first to be taken off the market. Many others have
since followed in their wake.
This
has been a positive thing for the most part. Growers are better educated on how
to manage pests, and they generally have more products to choose from than they
used to. Of course, it’s more expensive now to kill pests and the long-established
problems of pesticide resistance continue to plague us. But the future of
agriculture is promising – in spite of the many more mouths we have to feed.
And
through all of this the organic movement has felt the need to adapt its
message. From healthy soils it now focuses on pesticide-free food.
Unfortunately (for them) this will turn out to be a poor course to follow. The
credibility of the organic movement (already limited) will become even more
limited. Claims to better health and living can hardly be justified anymore. The Stanford Study is a clear case of this.
But
there have been hints of this for some time now. You may have been part of
taste tests that used to be popular. Two plates of carrots (or apples, grapes,
or other food) would be placed side-by-side. One plate would hold organic
carrots, the other would hold conventional carrots. The challenge was to taste a
difference between them. If you could taste a difference, then you had to rank
them by preference. In the tests I participated in, there were often
differences detected, and conventional produce tasted best. You may have
experienced the same thing. The reason for this is that food tastes best when
it is kept from spoiling. And the truth of the matter is that organically grown
foods spoil quicker than conventionally grown food.
Another
popular series of studies have looked at the productivity of conventional
farming compared to organic farming. In many of these studies, organic farms
produced less in acre-by-acre comparisons than conventional farms.
So
the question becomes, if conventionally grown food is tastier, is just as
healthy, and is less expensive than organically grown food, why should we
bother with organic foods at all?
The
answer may not be what you expect. We need organically produced food because it
is old fashioned. Or rather, the answer lies with old fashioned organic agriculture.
It lies with the soil. Organic farms that fail to compare favorably with
conventional farms do so because they are trying to copy conventional markets.
A dedicated organic grower that focuses on Albert Howard’s organic method of
composting can out-compete conventional growers in both the quantity and
quality of food produced. But this almost always happens on a small scale.
The
farm that focuses on organic soil fertility can harvest fresh produce over a
long growing season. If this is supplemented with modern pesticides (if they
are needed) a farm will out-compete conventional growers.
You
may say that this does not count as “organic” and you would be right. The rules
of the organic movement (having started in California) are now official
nationally (and are expanding globally). Using un-certified pesticides
disqualifies a product as “organic”.
My
response to all of this may seem harsh: Who Cares? If “organic” produce is not
healthier, is less tasty, and costs more than my grocery store produce, I’m not
going to buy the organic food. It doesn’t bother me to wash my vegetables.
But
there is still a big need to improve the soil. And I still keep my own vegetable
garden (and compost pile) because I much prefer the taste of fresh garden
produce. I promise you that my fresh garden salad tastes better than conventionally
grown salads (which taste better than flagging organic salads).
This
is because I use tastier varieties (that aren’t “tough” enough for shipping) that
come straight from plants that have been fed from rich compost. We may have a
lot of sandy soil here in Fresno but my garden is full of organic matter and my
plants love it. And they taste really good.
I
think it’s time to give Sir Albert Howard a closer look. We’ve learned our
lesson from Silent Spring. It’s time
to move on. If we’re really serious about our health, let’s go outside and
start a real organic garden. Let’s build up our soils.
