GMOs

Are genetically modified organisms (GMOs) a threat to organic agriculture? Are they dangerous when consumed? Do they lead to higher use of chemical herbicides and pesticides? And why aren’t GMOs labeled so we know which foods are made with them? We find and discuss the latest news on this critical issue.

Is Monsanto’s Roundup Killing Our Soil?

Roundup HerbicideWe’ve often argued against “biotech” or genetically modified crops and the accompanying use of glyphosate herbicide — trade name Roundup — because of its effects on human health, sustainability, and its culpability in creating a new class of glyphosate-resistant “superweeds” that are spreading across America’s farm country. Now comes word that Roundup is killing not just weeds but the very soil in which we grow our crops.

This article in The New York Times  explains the negative effects glyphosate has on soil, effects that include compaction and resultant runoff, the killing of beneficial microbes and bacteria, and the exhaustion of necessary minerals and other nutrients that plants require.

The article also shows how nearby use of Roundup affects farmers not using the “Roundup Ready” system of growing GMO crops coupled with the spraying of glyphosate. One farmer describes how he loses corn every time his neighbor sprays Roundup and the herbicide drifts onto his conventionally grown corn. Worse, his neighbor’s fields have become so compacted that every time it rains, Roundup-laden runoff floods his conventional crops. “Anything you put on the land affects the chemistry and biology of the land, and that’s a powerful pesticide,” the farmer is quoted as saying.

Scientific American On GMOs: Not So Scientific

GMO ArticleScientific American, the mass-market monthly magazine, has created a stir with its full-out recommendation that food products containing ingredients with genetically-modified plant sources NOT be labeled (really?).  An earlier article from this summer’s food issue (subscription required, brief only) argued that GMOs have been proven safe; end of discussion. Let’s ask again . . . really?

Both articles call into question Scientific American‘s supposed objectivity. Narrowly focused on just bits and pieces of the issues, the magazine seems to have bought in fully to the corporate, pro-GMO arguments while ignoring the impacts raising genetically-modified plants have on plant diversity, the parallel uses of pesticides and herbicides required by GMO plants, and the threats posed to the freedom of independent, small American farms. Worse, its seems to white wash recent scientific evidence that some GMOs have proven harmful to the health of livestock and humans. What gives?

We can only hope that somewhere a motivated and brave investigative journalist is looking into any connection the author of the article or “the editors” who wrote the opinion piece masquerading as fact about labeling GMOs to the corporations who champion and profit from the spread of GMOs. The pieces sure take the company line in support of the questionable technology to heart, sometimes even word for word. We can’t help but be suspicious. (more…)

Sustainable Farming, Soil, and Big Agriculture

Sustainable AgricultureCorporate farming has disrupted an independent economic model and a way of life that was common just a few generations ago. Things were different when America’s farming economy was based on countless small, independent producers who then sold their products at rural cooperatives or directly to markets. Today, a few large food producers including Cargill, Archer Daniels Midland, and Tyson, and a few large (mostly) chemical companies, including Dow Agro Sciences, Cargill and, yes, Monsanto, have a corner not only on our food supplies but the products used to raise them. This consolidation of our farm and food supplies creates huge problems, not just in this country, but world wide.

In the last few years, we’ve seen a reversal of this trend with independent, often organic farmers not only raising healthy food but being good stewards of the land. Yet the acreage involved is still miniscule compared to the vast miles of commercial farmland in the midwest, the south, and in California, where big corporate agriculture has a grip. (more…)

Why You’ll Always Have To Grow Tomatoes . . .

Homegrown Tomatoes. . . or buy them from your small, local organic farmer. This article on efforts to produce a tastier commercial tomato is, frankly, sad. We all know the problem with grocery store tomatoes (PDF): they’re bland if not completely tasteless. Compare them to the most mediocre tomato grown in someone’s back yard and that mediocre tomato shines by comparison. Compare them to any decent, heirloom tomato from your garden or a small, local, organic farmer and, well, there’s no comparison.

Not only do homegrown and small farm organic tomatoes taste better than commercial tomatoes, they have more nutrition.

So you have to feel bemused if not sorry for professor Harry Klee at the University of Florida’s Institute for Plant Innovation program. Sure, his goals are admirable: he’s trying to “build” a better supermarket tomato. That means more flavor. (more…)

Orange Disease: GMOS To the Rescue (Not)

GMO Orange TreeThe plague that’s sweeping orange groves across the world — it’s known as “citrus greening” — was discovered in Florida in 2005. With millions of trees at stake and huge amounts of money, big growers responded as they often do: spray more pesticides. It was thought that killing the insect that spreads the bacterium coupled with burning all the diseased citrus trees might solve the problem. You already know the answer to that one.

The usual cross-breeding of orange trees with disease resistant varieties couldn’t work because no one could find an orange tree that was resistant to the disease. So they came up with what they thought was the next best thing. Find another living thing that was resistant, or even immune, and graft its genes into the orange. Voila!, a genetically-modified solution. Considered donors, so far for this modification? Other kinds of trees, a couple vegetables, a virus and … wait for it… pigs! (more…)

Pesticides and Unintended Consequences

Pesticide DriftWe’ve already mentioned the fine documentary released early this summer More Than Honey, a film that looks at the behavior of bees as well as issues and consequences behind colony collapse disorder that’s sweeping the world. As the movie states, bee activity is responsible for a third of the food we eat. Losing them would have impacts well beyond the loss of some fruit. It could mean a complete change in the way we live. The movie shows us an example of a place where bees have already vanished and the consequences that followed.

The place is China. Seems that Mao Tzedog before his death in 1976 decided that a plague of sparrows was putting a large dent in grain production. So in the kind of short-sighted, ill-conceived wisdom that’s apparently shared by Chinese dictators and American corporate agricultural CEOs, Mao called for the elimination of sparrows. The killing of the sparrows released a swarm of insects, a problem that affected agriculture much more than the damage done by the birds. So massive spraying programs were instituted. The spraying not only killed harmful insects, it killed beneficial ones as well, including pollinators. Without bees, Chinese crops blossomed but didn’t produce. The solution? Hand pollination.

GMOs and European Trade Talks

GMO Trade TalksThe growing and use of genetically engineered crops are a big issue. Yet little has been done, despite consumer efforts, to label those products in the USA or ban their growth and use all together.

Europe has long been a beacon of sanity when it comes to banning the use of GMOs in processed food as well as the raising of GMO crops. The European Union prohibits or restricts the import of food products from the U.S. that contain ingredients from genetically modified crops. While GMO crops make up over 80% of the corn and over 90% of the soy raised in the U.S., those figures are closer to 1% in Europe. In the U.S. some 80% of the processed foods contain GMOs.

Now the corporate powers who profit from GMOs have found an opening into European markets. The TransAtlantic Trade and Investment Partnership (TTIP) talks that opened in June will consider the GMO restrictions among dozens if not hundreds of other disputes involving the U.S. and its European Trading Partners. Those talks are secret. (more…)

Composting GMOs

GMO Kitchen WasteYour friendly and equally inquisitive Planet Natural Blogger gets questions. Sometimes they’re real stumpers. Here’s one:

If you are composting GMOs without knowing it does it mean you are growing them by using the compost?

We had to think about this awhile. We know that the composting process is capable of great things. We know that it can help “repair” contaminated soils and prevent toxic runoff into our watercourses; that it can reduce to some degree the toxicity of soils contaminated with chemicial substances such as creosote; that it can even reduce the toxicity of explosive residues of the sort found in dumps on military reservations (but that it leaves behind another problem: mutigenicity).

But what happens when genetic plants are composted? Will the genetically-mutated materials break down? And will any of the components that the mutation generates — say the Bt (Bacillus thuringiensis) that acts as a pesticide in GMO corn — will those be broken down as well? (more…)

Weeds vs Herbicides: Weeds Win!

Applying HerbicidesAn article in The New York Times seems to celebrate weeds: their hardiness, their adaptability, their ability to quickly evolve. It’s overall theme? In the battle between weeds and chemical herbicides, weeds eventually and always win. And while it takes some reading between the lines, the article also draws conclusions that organic gardeners have known all along. One… herbicides can be dangerous. Two… a variety of techniques, many of them organic, are needed to actually reduce crop losses caused by weeds.

So why use herbicides? Their development (PDF) was thought to be a tremendous breakthrough. As far back as Roman times farmers spread salt on their fields to destroy their enemies’ crops. Modern weed killers were introduced during World War II and their use skyrocketed after that. Chemical companies soon learned that herbicides meant big money. But almost as quickly, weeds began to develop resistance to the chemicals. Today, it’s estimated that at least 217 varieties of weeds have developed resistance (follow the link to see a frightening photo of giant ragweed taking over a field of Roundup resistant corn).

Hybrid Broccoli Controversy

BroccoliThat so-good-for-you vegetable — broccoli — is in the news. A “dream team” of botanists, agrarians, and marketers has come together at Cornell University to create a broccoli that will grow in areas where the heat-sensitive cruciferous won’t normally grow. And therein lies the problem. Since nearly all commercial broccoli is grown in California, the plant suffers days of transportation before its delivered to midwestern, southern and eastern markets, a time that saps the broccoli of its fresh taste and snap. The new hybridized broccoli can withstand the relative evening warmth and humidity that has made successful commercial farming of broccoli east of the Rocky Mountains difficult. The New York Times  has the story.

The piece is actually a double profile of both broccoli and the plant physiologist who fronts the broccoli effort, Dr. Thomas Bjorkman. Bjorkman, himself a vegetarian, has envisioned making broccoli more readily available in American markets. He’s also sought to make it more palatable and nutritious. Apparently he’s succeeded. The new hybrid broccoli contains more glucoraphanin, a compound that’s been found to prevent cancer. (more…)
